A High-Performance and Noise-Robust Classifier from K-Dimensional tree-based Dual kNNSwe Swe Aung, Itaru Nagayama, Shiro TamakiSOPEJ_OctoberPattern Recognition, Robustness, KNN, Machine Learning, Facility DiagnosisDownload

The k-NN algorithm is a highly effective method for many application areas. Conceptually the other good properties are its simplicity and easy to understand. However, according to the measurement of the performance of an algorithm based on three considerations (simplicity, processing time, and prediction power), the k-NN algorithm lacks the high-speed computation and maintenance of high accuracy for different k values. The k-NN algorithm is still under the influence of varying k values. Besides, the prediction accuracy fades away whenever k approaches larger values. To overcome these issues, this paper introduces a kd-tree based dual-kNN approach that concentrates on two properties to keep up the classification accuracy at different k values and upgrade processing time performance. By conducting experiments on real data sets and comparing this algorithm with two other algorithms (dual-kNN and k-NN), it was experimentally confirmed that the kd-tree based dual-kNN is a more effective and robust approach for classification than dual-kNN and k-NN.

An Adaptive Morphological Operation for High-Performance Weather Image ProcessingSwe Swe Aung, Itaru Nagayama, Shiro TamakiIEIE_December_30, Adaptive morphological operation, Dilation, ErosionDownload

Morphological operations have been an integral part of the enhancement of digital imaging programs, especially for filtering noise to improve the quality of images by utilizing the two most basic morphological operations: erosion and dilation. The main role of dilation is to fill the defined region in an image with pixels, whereas erosion removes pixels from the region. As we know, the methods of erosion followed by dilation, or dilation followed by erosion, are indeed attractive approaches amongst researchers who deal with filtering noise problems. However, these approaches need more computational time and have a high-percentage chance of losing essential pixel area. To cover these issues, this paper introduces a new approach called an adaptive
morphological operation to boost the performance of image enhancement. Based on 2011, 2013, 2015, and 2016 weather image datasets collected from the WITH radar installed on the rooftop of the Information Engineering building, University of the Ryukyus, the experimental results confirm
that the proposed approach is more efficient than the conventional approaches.

Investigation into Tolerance of Mislabeling when Classifying Patterns with Dual-kNNSwe Swe Aung, Itaru Nagayama, Shiro TamakiIEIE_December_30Dual-kNN, Density-based kNN, k-NN, Mislabeled noiseDownload

As we know, machine learning algorithms are powerful tools for a variety of application domains, giving widely divergent dimensions, such as reliability, precision, robustness, high-speed solutions, etc. Likewise, the other critical dimension that a well-designed learning algorithm should occupy is strength against unpredictable and phenomenal noise. For this critical dimension, we
introduce a new approach, dual k-nearest neighbors (dual-kNN), to investigate the tolerance level for mislabeling based on different injected-noise levels. Literally, dual-kNN is a reborn algorithm of k-nearest neighbors (k-NN) aiming to reduce the influence of a steady decrease in prediction accuracy over increasing k values. What is more, dual-kNN is proven to have higher classification accuracy in many application domains. For the primary goal of this paper, we mainly emphasize investigating dual-kNN’s resistance level to mislabeled classes. Provably, our empirical experimentations describe how dual-kNN has a higher resistance level to mislabeling than normal
k-NN, density-based kNN, and logistic regression, for noise levels of up to 50%. The practical datasets applied within this paper are medical data files from the University of California, Irvine (UCI) Machine Learning Repository.

Noise-tolerance Investigation into Dual-kNN Pattern ClassificationSwe Swe Aung, Itaru Nagayama, Shiro TamakiIEIE_June _30k-NN, Dual-kNN, Logistic regression, Neural network, RobustnessDownload

The performance of an algorithm is usually measured in three dimensions (simplicity, processing time, and prediction power). In addition, we should take into account the noise resistance level in those measures. For this reason, this paper focuses on investigating the noise-tolerance level of dual k-nearest neighbors (dual-kNN) primarily based on five noisy medical diagnosis problems. Literally, dual-kNN is a reborn version of the k-nearest neighbors (k-NN) algorithm with a new observation idea in the classification process with a collaborative effort between the first and second nearest neighbors of an observed instance. It was recently proven that dual-kNN has high prediction accuracy for a variety of real-world data sets, especially so in unbiased data sets. Thus, in this report, not only the prediction accuracy of dual-kNN is compared with normal k-NN, logistic regression, and the neural network, but we additionally investigate the noise tolerance in the aforementioned approaches. The practical data sets applied in this paper are medical data files from the University of California, Irvine, Machine Learning Repository. In this report, the new approach to dual-kNN commences with better prediction accuracy, and higher noise resistance is presented, in comparison with normal k-NN, logistic regression, and neural networks.

Regional Distance-based k-NN ClassificationSwe Swe Aung, Itaru Nagayama, Shiro TamakiJICE_April_5k-NN, RD-kNNDownload

The k-Nearest Neighbor (k-NN) is very simple and powerful approach to conceptually approximate real-valued or discrete-valued target function. Many researchers have recently approved that K-NN is a high-prediction accuracy algorithm for a variety of real-world systems using many different types of datasets. However, as we know, k-NN is a type of lazy learning algorithms as it has to compare to each of stored training examples for each observed instance. Besides, the prediction accuracy of k-NN is under the influence of K values. Mostly, the higher K values make the algorithm yield lower prediction accuracy according to our experiments. For these issues, this paper focuses on two properties that are to upgrade the classification accuracy by introducing Regional Distance-based k-NN (RD-kNN) and to speed up the processing time performance of k-NN by applying multi-threading approach. For the experiments, we used the real data sets (wine, iris, heart stalog, breast cancer, and breast tissue) from UCI machine learning repository. According to our test cases and simulations carried out, it was also experimentally confirmed that the new approach, RD-kNN, has a better performance than classical kNN.

Dual-kNN for a Pattern Classification ApproachSwe Swe Aung, Itaru Nagayama, Shiro TamakiIEIE_October_30Dual-kNN, kNN, Robustness, Pattern classificationDownload

Classification is a process of discovering and categorizing objects from large data storage that have similar characteristics, properties, and patterns. One of the most widely used classification methods in machine learning is the k-nearest neighbors (k-NN) algorithm. The unique property of k-NN that appeals to researchers is its simplicity, so it can be applied successfully over a wide field. However, according to measurement of the performance of an algorithm based on three considerations (simplicity, processing time, and prediction power), the k-NN algorithm lacks highspeed computation and maintenance of high accuracy for different K values. In other words, k-NN is a heuristic classification approach. Besides, the prediction accuracy fades away whenever K approaches larger values. To overcome these issues, this paper presents a dual-kNN that concentrates on two properties to keep up the accuracy at different K values and upgrade processing time performance. By conducting experiments on real datasets and comparing this algorithm with k-NN, it was also confirmed that the new dual-kNN is an effective and robust
approach to classification.

Traffic Flow Estimation System using a Hybrid ApproachSwe Swe Aung, Itaru Nagayama, Shiro TamakiIEIE_May_31, Decision tree, Logistic regression, Support vector machineDownload

Nowadays, as traffic jams are a daily elementary problem in both developed and developing countries, systems to monitor, predict, and detect traffic conditions are playing an important role in research fields. Comparing them, researchers have been trying to solve problems by applying many kinds of technologies, especially roadside sensors, which still have some issues,
and for that reason, any one particular method by itself could not generate sufficient traffic prediction results. However, these sensors have some issues that are not useful for research. Therefore, it may not be best to use them as stand-alone methods for a traffic prediction system. On that note, this paper mainly focuses on predicting traffic conditions based on a hybrid prediction
approach, which stands on accuracy comparison of three prediction models: multinomial logistic regression, decision trees, and support vector machine (SVM) classifiers. This is aimed at selecting the most suitable approach by means of integrating proficiencies from these approaches. It was also
experimentally confirmed, with test cases and simulations that showed the performance of this hybrid method is more effective than individual methods.

Plurality Rule–based Density and Correlation Coefficient–based Clustering for K-NNSwe Swe Aung, Itaru Nagayama, Shiro TamakiIEIE_June 30, Classification, Density-based, K-NN, DPC-KNN-PCA, Processing timeDownload

k-nearest neighbor (K-NN) is a well-known classification algorithm, being feature space–based on nearest-neighbor training examples in machine learning. However, K-NN, as we know, is a lazy learning method. Therefore, if a K-NN–based system very much depends on a huge amount of history data to achieve an accurate prediction result for a particular task, it gradually faces a processing-time performance-degradation problem. We have noticed that many researchers usually contemplate only classification accuracy. But estimation speed also plays an essential role in realtime prediction systems. To compensate for this weakness, this paper proposes correlation coefficient–based clustering (CCC) aimed at upgrading the performance of K-NN by leveraging processing-time speed and plurality rule–based density (PRD) to improve estimation accuracy. For experiments, we used real datasets (on breast cancer, breast tissue, heart, and the iris) from the University of California, Irvine (UCI) machine learning repository. Moreover, real traffic data
collected from Ojana Junction, Route 58, Okinawa, Japan, was also utilized to lay bare the efficiency of this method. By using these datasets, we proved better processing-time performance with the new approach by comparing it with classical K-NN. Besides, via experiments on real-world datasets, we compared the prediction accuracy of our approach with density peaks clustering based on K-NN and principal component analysis (DPC-KNN-PCA).

Intelligent Traffic Prediction by Multi-sensor Fusion using Multi-threaded Machine LearningSwe Swe Aung, Itaru Nagayama, Shiro TamakiIEIE_December_23, Intelligent transportation system, K-nearest neighbor, Naïve bayesDownload

Estimation and analysis of traffic jams plays a vital role in an intelligent transportation system and advances safety in the transportation system as well as mobility and optimization of environmental impact. For these reasons, many researchers currently mainly focus on the brilliant machine learning–based prediction approaches for traffic prediction systems. This paper primarily addresses the analysis and comparison of prediction accuracy between two machine learning algorithms: Naïve Bayes and K-Nearest Neighbor (K-NN). Based on the fact that optimized estimation accuracy of these methods mainly depends on a large amount of recounted data and that
they require much time to compute the same function heuristically for each action, we propose an approach that applies multi-threading to these heuristic methods. It is obvious that the greater the amount of historical data, the more processing time is necessary. For a real-time system, operational response time is vital, and the proposed system also focuses on the time complexity
cost as well as computational complexity. It is experimentally confirmed that K-NN does much better than Naïve Bayes, not only in prediction accuracy but also in processing time. Multithreading-based K-NN could compute four times faster than classical K-NN, whereas multithreading-based Naïve Bayes could process only twice as fast as classical Bayes.

Mining Data for Traffic Detection System Using GPS_enable Mobile Phone in Mobile Cloud InfrastructureSwe Swe Aung, Thinn Thu NaingIJCCSA_June_1, GPS-enable Mobile Phone, traffic detection,Download

The increasing need for traffic detection system has become a vital area in both developing and developed countries. However, it is more important to get the accurate and valuable data to give the better result about traffic condition. For this reason, this paper proposes an approach of tracking traffic data as cheap as possible in terms of communication, computation and energy efficient ways by using mobile phone network. This system gives the  information of which vehicles are running on which location and how much
speed for the Traffic Detection System. The GPS sensor of mobile device will be mainly utilized to guess a user’s transportation mode, then it integrates cloud environment to enhance the limitation of mobile device, such as storage, energy and computing power. This system includes three main components: Client Interface, Server process and Cloud Storage. Some tasks are carried out on the Client. Therefore, it greatly reduces the bottleneck situation on Server side in efficient way. Most of tasks are executed on the Server
and history data are stored on the Cloud Storage. Moreover, the paper mainly uses the distance based clustering algorithm in grouping mobile devices on the same bus to get the accurate data.

Blockchain-based Cross-Border Educational Transaction SystemSwe Swe Aung, Hus Mon Kyi, Yuzana, Thinn Thu Naing11-15, NovemberBlock-based cross-border educational transaction system, block-chain, cross-border educaltionDownload

Cross-border education can be termed as the movement of student, research, academic exchange programs and institutions across national borders with the provision of international education programs. In this case, the secure and speedy education credit transfer and exchange of student records are the important factors for the cross-border education system. Thus, this paper proposes a system called “Blockchain-based Cross-Border Educational Transaction System” for the higher education industry. Blockchain technology is one of the megatrends for recent years. It is potentially a revolutionary means of secure and transparent data sharing and processing in a wide variety of sectors including the education sector. The important concept of blockchain technology is a combination of secured distributed ledger, cryptocurrency and smart contract system. That concept is very appropriate at creating trusted and secured information processing for large and heterogeneous sets. Therefore, the blockchain-based cross-border educational transaction system enables the education industry to transfer and exchange the secure education credit and academic records for students, and other stakeholders such as government organizations, companies, and other institutions. Besides, maintaining educational records in the blockchain can protect from an unexpected natural disaster. This paper will propose and discuss the system framework that consists of three layers. The first layer would be an interface layer for application development. The second layer provides smart contract service, core service of blockchain, for generating trusted education credit, grading and certificate transaction, as well as for secure agreements of exchange and collaborative educational processes. The last layer is a data storage layer including database methodologies and distributed computing methods. The proposed system would overcome the barrier of traditional cross-border transaction system by allowing the globally secure, transparent, and reliable education transaction services and collaborative processes among universities in different regions.

An Attempt to Forecast All Different Rainfall Series by Dynamic Programming ApproachSwe Swe Aung, Itaru Nagayama, Shiro Tamaki13-14 November 2018, , Forecast All Different Rainfall Series, Dynamic Programming Approach, Polynomial RegressionDownload

Unexpected heavy rainfall has been seriously occurred in most parts of the world, especially during monsoon season. As a serious consequence of heavy rainfall, the people in those areas battered by heavy rainfall faced many hardship lives. Without exception, prevention is the best way of minimizing these negative effects. In spite of all, we developed a rainfall series prediction system for different series patterns by applying the dynamic programming approach aiming to acquire the rainfall level of the whole rainfall cycle. The simple idea behind the proposed dynamic programming approach is to find the similarity of two rainfall sequences upon the maximum match of the rainfall level of those sequences. Based on 2011 and 2013 real data sets collected from WITH radar, which is installed on the rooftop of Information Engineering, University of the Ryukyus, the comparison between the conventional approach (Polynomial Regression) and the proposed approach is investigated. These correlation experiments confirm that the dynamic programming approach is more efficient for predicting different rainfall series.

It is the most important part that getting and performing the accurate traffic data in all Traffic Prediction System.  This paper introduces an approach  of tracking traffic data using the cheapest way and it was computed the traffic data in terms of communication, computation and energy efficient ways. Mobile devices are becoming an important role not only for personal contact, but also for business and environmental sensing application. The GPS sensor of mobile device will be mainly utilized to guess a user’s transportation mode, then it integrates cloud environment to enhance the limitation of mobile device, such as storage, energy and computing power.  This system includes three main components: Client Interface, Server process and Cloud Storage.

Most of tasks are executed on the Server and history data are stored on the Cloud Storage. Firstly, the user’s transportation mode, motorize or non-motorized, is analyzed on the client side using raw GPS data, instead of submitting frequently raw data to data center. If it is only the motorize mode, some useful traffic data are offloaded to cloud.  On the server side, all motorize mode are not taken into account as traffic data. In this case, the mobile data that comes from the same location are recognized as one proves. Later, these data are used as history data for future prediction to perform more accurate traffic information.

Communities among users play the popular role for
days of Social Network and the presence of groups of nodes that

connected to nodes of different groups. So community detection
algorithms are come to be the key to detect the user who are
interact with each other in social media. However, there are still
challenges in considering of some nodes have no any common
node within the same group as well as some nodes have no any
link to the other node. It can be used similarity measure based on
neighborhood overlapping of nodes to organize communities and
to identify outliers which cannot be grouped into any of the
communities. In this paper, we detect communities and outliers
from Edge Structure with neighborhood overlap by using nodes
similarity. The result implies the best quality with modularity
measurement which leads to more accurate communities as well
as improved their density after removing outliers in the network
structure.

Challenges of detecting communities among users’ interactions play

Considering the community detection is motivating from the similarity

Community Detection in Social Network with Outlier RecognitionHtwe Nu Win, Khin Thidar LynnMarchSocial Network, Community Outlier Edge Structure Overlapped Neighbor NodeDownload

Exploring communities and outliers in Social Network is based on considering of some nodes have overlapped neighbor node within the same group as well as some nodes have no any link to the other node or have no any overlapped value. The existing approaches are based on the overlapping community detection method were only defined the overlap nodes or group of overlap nodes without thinking of which nodes might have individual communities or which nodes are outliers. Detecting communities can be used the similarity measure based on neighborhood overlapping of nodes and identified nodes so called outliers which cannot be grouped into any of the communities. This paper proposed method to detect communities and outliers from Edge Structure with neighborhood overlap by using nodes similarity. The result implies the best quality with modularity measurement which leads to more accurate communities as well as improved their density after removing outliers in the network structure.

Organizations in both public and private sectors
have become increasingly dependent on electronic
data processing. It is essential to protect the
communication channels and the interfaces of any
system that handles information that could be the
subject of attacks e.g. personal mail, electronic
commerce and other financial transactions.
Protecting the important data is of utmost concern to
the organizations and cryptography is one of the
primary ways to do the job. Public Key
Cryptography is used to protect digital data going
through an insecure channel from one place to
another. This paper will implement a secured
architecture for the various medical records by using
RSA public key encryption algorithm and different
authentication levels with the help of Agent
Technology. RSA algorithm, asymmetric public key
algorithm, is used to encrypt and decrypt the data.
Agent Technology is used to retrieve required data
efficiently and effectively. Since, medical records are
confidential; it needs to be secured over the
communication channel. So that security agent
encrypts the requested data before sending to the
target user. Personal agent is responsible for
requesting data, carrying user preferences and user
authentication to the remote server and bringing
data back to the user. Data agents are used for
generating the relevant data to the user (Personal)

A PSO-GA based hybrid Algorithm for the composite SaaS Placement Problem in the CloudYin Nyein Aye, Thinn Thu NaingMay_5Cloud computing, Software as a Service, PSO-GA, StorageDownload

Cloud computing is an emerging computing paradigm in which applications, data and IT resources are provided as a service to users over the Internet. One kind of services that can be offered through the cloud is Software as a Service or (SaaS). For SaaS placement in the Cloud, the problem relates to how a composite SaaS should be placed in a Cloud by the Cloud’s providers such that its performance is optimal based on its estimated execution time. The challenges in the SaaS placement process rely on several factors, including the size of the Cloud network, SaaS competing resource requirements, SaaS interactions between its components and SaaS interactions with its data components. This paper proposes a PSO-GA (Particle Swarm Optimizing-Genetic Algorithm) based hybrid algorithm to the composite SaaS placement problem in the Cloud storage for minimizing the execution time and execution cost of applications on the resources provided by cloud.

Minimizing Essential Set Based Feature Selection for Cancer ClassificationKhin May Win, Nang Saing Moon KhamFebruary_14DNA microarray, feature selection, cancer classification ,recursive feature elimination, support vector machinesDownload

Many methods for classification and gene
selection with microarray data have been developed.
Some methods usually give a ranking of genes.
Relevant gene rank criteria is derived from SVM and
based on generalization error bounds with respect to
genes variable .We address feature selection problem
for classification because of small samples with high
dimensionality of genes. The best choice of gene
subset means selection of relevant features that is a
key for building a more accurate classifier. We
propose a new method using minimizing essential
set (MES) generated based on the nearest neighbor
rule. It is related to structural risk minimization and
thus leads to good generalization. The proposed
method is compared to some standard feature
selection methods with three real datasets. Our
approach is computationally efficient with better
classification performance.

Feature Subset Selection for Cancer Classification using Maximized Margin of Support Vector MachinesKhin May Win, Nang Saing Moon KhamJuly_24DNA microarray, feature selection, cancer classification, embedded method, support vector machinesDownload

Nowadays, microarray datasets are characterized by a large number of gene expression levels for each patient and a relatively small number of patients. Data can grow along two dimensions of fields (called attributes) and the number of cases, abnormal functionalities. Early detection for possible cancer cannot get by large scale data. The problem become feature selection with classification accuracy because of small samples with high dimensionality of genes .The best choice of gene subset means selection of relevant features that is a key for building a more accurate classifier.
The traditional statistical methods with linear function are not capable of discovering nonlinear relationships in microarray data. Data overfitting arises when the number of features is very large. Identifying relevant variables give more insight into the nature of corresponding classification problem and tend to be better predictive performance. Incorporating feature selection is a fairly straightforward procedure for linear or nonlinear support vector machine (SVM) classifiers.

We propose a new method that uses support vector machines with features ranking technique based on recursive feature elimination (RFE).Among various feature selection methods, embedded approach of feature ranking is particularly attractive. A fixed number of top ranked features are selected for design of classifier; a threshold can be set on the ranking criterion. The feature with the smallest ranking criterion is eliminated at each step. The ranking criterion is obtained from the weights of SVM that trained on the subset of features. SVM composes the transformation function and the dot product in the higher dimensional space into a single kernel function. The goal of maximum margin classification in binary SVM is to separate the two classes by a hyperplane. We can decide the optimal hyperplane which reduces the generalization error. The main objectives are to obtain profiles of relevant genes tend to predict the cancer class of unknown patient, prediction accuracy may improve by discarding irrelevant variables and apply the proposed method into an interface that can easily be used by clinicians.
This work is to be optimized which SVM model selection will be particularly important and scalable in microarray data analysis. From our work, experiments on real data sets from UCI machine learning repository can indicate that new method outperforms other feature selection method in terms of classification accuracy. On the other hand, machine learning methods may be able to objectively interpret all available results for the same patient and increase the diagnostic accuracy for each disease.

This paper has presented different approach for variables of feature selection algorithm. This criterion is derived from generalization error bounds of the SVM theory: weight vector norm ||w||2 and upper bounds of the leave-one-out error. In addition ,it implements a criterion similar to the SVM-RFE measures the sensitivity of ||w||2 to a variable by computing the change in ||w||2 when this given variable has been removed. Lastly, as it has the lowest time complexity, it may be support for practical applications. Intuitively, one may justify the behavior by the over fitting effects occurring due to the small number of data and the large number of variables. We may improve the performance of our algorithms by using an alternate search strategy combining the feature selection process into an overall optimization problem. Though the data set is related to cancer, the method is generic and can be applied on other large data sets that require feature selection.

Data preprocessing needs to make data cleaning which routines work to clean the data by filling in missing values, smoothing noisy data, identifying, removing outliers, and resolving inconsistencies. Data transformation operations are additional data preprocessing procedures that would contribute towards the success of the mining process. Data normalization transforms data values for different database attributes into a uniform set of units or into a uniform scale range. Classification is the process of finding the common properties among different entities and classifying them into classes. A decision tree is built from a set of training data having attribute values and a class name. In this paper, the original dataset is transformed using three different normalization methods such as min-max, z-score and decimal scaling normalization. The normalized dataset is evaluated using decision tree and analyses number of leaf nodes and accuracy. Comparisons between the three normalization methods were discussed in this paper.

Fingerprints were one of the first forms of
biometric authentication to be used for law
enforcement and civilian applications. Contrary to
popular belief, despite decades of research in
fingerprints, reliable fingerprint recognition is an
open problem. Extracting features out of poor
quality prints is the most challenging problem
faced in this area. So it is essential to enhance the
prints prior to feature extraction. This paper
proposes an approach for fingerprint image
enhancement based on the Gabor Filter. Ridge
orientation, one of the important parameters of the
filter, is estimated using the Sobel operator. But,
the estimation of ridge frequency, which is another
important parameter, is eliminated by giving a
fixed value that leads to a fast enhancement

The main goal of this project is to develop and implement a
prototype of two-axis solar tracking system based on a PIC
microcontroller. The parabolic reflector or parabolic dish is
constructed around two feed diameter to capture the sun’s energy.
The focus of the parabolic reflector is theoretically calculated
down to an infinitesimally small point to get extremely high
temperature. This two axis auto-tracking system has also been
constructed using PIC 16F84A microcontroller. The assembly
programming language is used to interface the PIC with two-axis
solar tracking system. The temperature at the focus of the
parabolic reflector is measured with temperature probes. This
auto-tracking system is controlled with two 12V, 6W DC gear
box motors. The five light sensors (LDR) are used to track the sun
and to start the operation (Day/Night operation). Time Delays are
used for stepping the motor and reaching the original position of
the reflector. The two-axis solar tracking system is constructed
with both hardware and software implementations. The designs of
the gear and the parabolic reflector are carefully considered and
precisely calculated.

Enhanced Battery Life of Mobile Device by Computation Offloading Decision AlgorithmMi Swe Zar Thu, Hsu Mon KyiFebruaryMobile Cloud Computing, Computation Offload-ing, Wireless Network Bandwidth, Energy, Computation Offloading DecisionDownload

Functionality on mobile device is ever richer in daily life. Mobile devices have limited resources like battery life, storage and processor, etc. Nowadays, Mobile Cloud Computing (MCC) bridges the gap be-tween the limited capabilities of mobile devices and the increasing user demand of mobile applications by of-floading the computational workloads from local de-vices to the remote cloud. Deciding to offload some computing tasks or not is a way to solve the limitations of battery life and computing capability of mobile de-vices. Application offloading is energy efficient only under various conditions for determining where/which code should be executed. This paper presents a Com-putational Offloading Decision Algorithm (CODA) , to save the battery life of mobile devices, taking into ac-count the CPU load, state of charge, network band-width and transmission data size. The system can take decision which method should be offloaded or not based on different context of the mobile device to ob-tain minimum processing cost. Numerical study is carried out to evaluate the performance of system. Exper-imental result will demonstrate that the proposed algo-rithm can significantly reduce energy consumption of mobile device as well as execution time of application.

ICTDownload

Educational prospects for the regions
which are the outside of the main capital in Myanmar are
reluctant to reach to the goal. The educational,
socioeconomic developments of the local people in the Shan
state has been encountered as a lot of challenges in everyday
life and the vast areas are beyond the opportunities.
According to 2014 official census statistics, the percentage of
illiterate in the urban area is only 15% of the population of
the Shan state whereas 42.1% are illiterate in the rural area.
It is only about 19.75% of primary school students in Shan
State reach high school. And also 3.43% of the total
population of Shan state who completed the highest level of
education such as College and University. This is our main
contribution of the research for the ethnic students weak in
Myanmar language and English language consequently they
have rare chances to connect to the science and technology.
As lends a hand of ICT, this paper describes the preliminary
approach for the creation of the machine readable
dictionary, can provide the meaning of Myanmar, English
and Pa-O language words vice versa. In this paper we
proposed dictionary building design process model and the
framework for the development of the multilingual
dictionary that used the traditional building method, such as
theory driven process. As Pa-O language is such a kind of an
under-resourced language, the data resources are rarely
hard to find. Hitherto, there is no officially printed dictionary
for Pa-O language to Myanmar language and also English
language as well. As a preliminary approach we performed
the data collection, the data identification stairs of the
proposed design process model in this paper. We collected
26174 Pa-O words with related meaning of Myanmar words
and analyzed these words, we discovered the four inference
observations presented in this paper. We noticed that Pa-O
language have 33 consonants same as Myanmar language
whereas the phonetics, some vowels, medial are dissimilar.
The Pa-O language words started with the consonant of [A,
အ] are observed as the most widely used word about 4782
words and the second most are started with the consonant of
[Ta, တ] about 2612 words. Our purpose is being the
University of Computer Studies (Taunggyi) in the Shan state,
we craft with the support of Information technology
innovation to this region. It enforces not only widen the ICT
sectors but also for arising homogeneous developing and the
enormous prosperity of the economic, education and social
sectors in all areas of mountain and land in Myanmar.

scheduling on private cloud infrastructure and
(ii) real time scheduling that is invoked for
multimedia applications running on virtual
machines. First is resource level scheduling and
second is application level scheduling. This
system analyzes first level scheduling steps by
applying an analytical performance model using
Stochastic Markov chain. Moreover, a real time
scheduling algorithm is presented for
application level to analyze real time
multimedia applications running on
virtualized servers. According to performance
evaluation, this system describes the detail
analysis of virtual resources and allocation steps
based on the criteria such as user request
completion probability, mean response time.

A Matching Process of Handwriting between Exhibit and SpecimenSoe Hae Mar, Nan Saw KalayarMarch_9preprocessing, texture analysisDownload

In this paper we present a matching process of handwriting between exhibits and specimen of Myanmar handwriting documents. This is also a method to identify the writer of Myanmar handwriting documents. Many methods have been reported for handwriting-based writer identification. Most such techniques assume that the written text is fixed. There are many methods for writer identification or signature verification. They are the kinds of content dependent identification methods. But our method is a content independent method. In our method, we take the handwriting as an image containing some special texture, and writer identification is regarded as texture identification. We apply the well-established multi-channel Gabor filtering technique to extract features and a Weighted Euclidean Distance classifier to fulfill identification task. The result of this paper will confirm whether handwriting of specimen is the true writer of the exhibit.

Blockchain-based Cross-Border Educational Transaction SystemSwe Swe Aung, Hsu Mon Kyi , Yuzana, Thinn Thu NaingNovember_14Blockchain, Cross-border transaction, Blockchain-based cross-border educational transaction, Cross-border educationDownload

Cross-border education can be termed as the movement of student, research, academic exchange programs and institutions across national borders with the provision of international education programs. In this case, the secure and speedy education credit transfer and exchange of student records are the important factors for the cross-border education system. Thus, this paper proposes a system called “Blockchain-based Cross-Border Educational Transaction System” for the higher education industry.
Blockchain technology is one of the megatrends for recent years. It is potentially a
revolutionary means of secure and transparent data sharing and processing in a wide variety of sectors including the education sector. The important concept of blockchain technology is a combination of secured distributed ledger, cryptocurrency and smart contract system. That concept is very appropriate at creating trusted and secured information processing for large and heterogeneous sets. Therefore, the blockchain-based cross-border educational transaction system
enables the education industry to transfer and exchange the secure education credit and academic records for students, and other stakeholders such as government organizations, companies, and other institutions. Besides, maintaining educational records in the blockchain can protect from an unexpected natural disaster.

This paper will propose and discuss the system framework that consists of three layers. The first layer would be an interface layer for application development. The second layer provides smart contract service, core service of blockchain, for generating trusted education credit, grading and certificate transaction, as well as for secure agreements of exchange and collaborative educational processes. The last layer is a data storage layer including database methodologies and distributed computing methods.
The proposed system would overcome the barrier of traditional cross-border transaction system by allowing the globally secure, transparent, and reliable education transaction services and collaborative processes among universities in different regions.

This study aimed to reveal that the internship program is important in
employability of engineering graduates in Myanmar. In Myanmar, an internship program is the best approach to explore career opportunities in the technological industry but most of engineering students do not have opportunities to take internship program. In our neighboring countries such as Singapore, Malaysia, India, Vietnam, etc., information technology and computer studies are very much in demand among businesses; the internship is likely to be very good compensated. But in our country, Myanmar, we have many challenges for the successful implementation of internship program of engineering institutes as well as other kinds of universities. Moreover, the engineering institutes in Myanmar are reformed their curriculum that internship program is a part of the curriculum. So, the final
year engineering students cannot pass their final examination without finishing their
internship program successfully. In this study, the major challenges of internship program, especially in engineering institutes, are discussed as well as it proposed the feasible solution for the problem of getting rare opportunities to be the interns.
This study also analyzed the employability of engineering graduates of a public
university in computer studies and it show that employability is improved for the graduates who have chances of internship program. This study also accessed the performance of interns evaluated by the manager or supervisor of different companies where interns deployed. Qualitative type of research methodology is used to analyze primarily and required data are collected also qualitatively from the University of Computer Studies (Taunggyi), which is one the IT engineering institute in Myanmar. The results proved that the capabilities of IT engineering graduates are drastically improved after attending internship program and the employability of engineering graduates are in progress.

Outcome-based Education System using Blockchain TechnologyHsu Mon Kyi, Swe Swe Aung, Yuzana, Thinn Thu NaingNovember_14OBE, blockchain, cryptocurrency, smart contractDownload

Outcome-Based Education (OBE) is a student-centric teaching and learning methodology in which the course delivery, assessments are planned to achieve stated objectives and outcomes.   Outcome-based education focuses on: (i) Student assessments are designed to measure the learners’ achievement of the learning outcomes (ii) Backward design of curriculum where courses and learning experiences are designed to help learners to achieve the learning outcomes (iii) Constructive alignment of learning outcomes, curriculum, teaching and learning methods, and student assessments. In OBE system, the student evaluation result is decided by educational stakeholders. Thus, the important problem of traditional OBE system can be absent to evaluate the student learning, abilities and states by educational stakeholders. As a next problem, society is unable to effectively evaluate the teachers and students as well as student evaluation results. Moreover, traditional document records can be destroyed in the case of natural disasters or wars.

            To fulfill those requirements, this paper designs a system, entitled “Outcome-based Education System using Blockchain Technology”. The important concept of Blockchain technology is a combination of secured distributed ledger, cryptocurrency and smart contract system. Blockchain is a reliable mechanism, and the development of blockchain brings significant benefits to education including providing a secure data processing platform, cost-saving, immutable and enhancing trust and transparency. Therefore, blockchain technology is applied to the traditional OBE system for higher education. In this case, this research focuses on the university curriculum and student credit system specialized in computer science and technology as a case study. The intended outcomes of this system would be (i) ensure the secure, reliable and robustness services for credit transfer and industry relationship (ii) support unique standardization for student data between all institutions and universities linkage.

Student-Centered Course Design: Reinforcing English as a Foreign Language (EFL) Students' Four Skills towards Student-Centered Learning through Classroom ActivitiesWin Theingi Myint, Nayzar Aye, Phyu Phyu Kyaing2020_Mayclassroom activities, student-centered learning, educational goal, facilitators, competencyDownload

This research paper focuses on the use of classroom
activities to reinforce EFL students’ four skills in the
student-centered course. Students play the center role in
the student-centered learning process. They actively
engage in classwork activities and collaborate with
their peers under the guidance of the teachers in the
student-centered classrooms. Moreover, students are
active participants for their educational goal, while
teachers are educators and they acts as facilitators or
activators in the student-centered learning. Eventually,
a student-centered classroom is a place for students to
create a positive environment for learning, where they
can choose and do classroom activities effectively.
Thus, student-centered learning environment is one of
the most effective ways to help students develop their
four skills independently. The competency in four skills
is also vital for EFL (English as a Foreign Language)
students and the integration of the four skills in their
learning process helps them to be active learners.
Therefore, developing students’ competency in four
skills means reinforcing their communicative
competence so that they can communicate in real life
situations.

The main concern of this study is to examine the
theoretical knowledge of Third year and Fourth year
English specialization students of Mandalay University
of Foreign Languages by exploring the translation
methods commonly employed in “The Choice”, the
translation of the Myanmar Short Story, “Yway-Chal-
Paing-Khwint” of SoeHlaing Tint translated by Zaw
Tun. The research methods used in this study are both
qualitative and quantitative. The data for this study
were collected from 48 Third year English
specialization students and 61 Fourth year English
specialization students from Mandalay University of
Foreign Languages. The translation methods were
investigated based on the theory of Newmark (1988).
The research found that both Third year and Fourth
year English specialization students were weak in the
knowledge of semantic translation method and
idiomatic translation methods because their study and
practice of translation methods do not go beyond the
classroom. They need to make more practice in the outof-
the- classroom situations. The translator used 5 out
of 8 translation methods in the translation of the short
story. The most frequently used translation method is
semantic translation. It was found that using semantic
translation method has a positive effect on the
translation text because it can give the readers the
aesthetic pleasure with the atmosphere of the original

The more useful and understand classifiers are needed to get the high accuracy of classification result on the large amount of text document due to the increasing number of complex documents and text documents. The main expected goal of classification on text documents is to exactly categorize the text piece into the various predefined categories. Because of rapidly improvement of using information technology, the automatically classification task on the online text document is become a main role for the discovery and collection information among the large amount documents. Moreover, the various methods of classification and algorithms for classification are improved by previous researchers however these methods and algorithms needed to filter the documents data before classification of these documents. Keeping these requirements, this system implements the idea problem of classifiers on unseen data classification for text documents that are not homogenous. In this proposed system, the filtering step is used before classification step on the text documents to get the better performance of text documents classification. C4.5, Support Vector Machine and Naïve Bayes from the machine learning approaches are used in the classification step of the system, the text documents the structure of the filter is based on dataset (training and testing) then these dataset are processed by the filters without changing behavior of the document structure. Data Discretization is a popular and useful step in the process, since it is easier for classifiers with discrete attributes value rather than continuous attributes value. In the preprocessing step of this system, data discretization is used to discretize the value of numerical attributes in the text document dataset into nominal attributes. Newsgroup data are employed to test the unseen test data and the performance efficiency of classification used filters are analyzed.

Overlapping Community Detection Using Centrality Measure and Local Seed InformationNyunt Nyunt SeinMay 30, seed expansion, overlapping community detection, community detectionDownload

Social Network Analysis (SNA)is the process of investigative social structures through the use of networks and graph theory. One of the most applicable features of graphs representing the real-world datasets is their community structure. Community detection is an important task in social network analysis. Communities are intuitively characterized as “unusually densely knit” subsets of a social network. When in real datasets, many vertexes belong to many communities, therefore overlapping community detection becomes a prominence topic in social analytic research fields. In this paper, we present a new overlapping community detection method based on local seed selection and local seed expansion approach. In our proposed method, we first partitioned the graph into disjoint clusters, and then select the node with highest eigenvector centrality value as seed node for each cluster and then expand these seed node to obtain the overlapping communities. We test our algorithm on small scale real-world datasets. Experimental results show that our presented algorithm outperforms in accuracy than other two popular overlapping community detection methods.

The first part is to create simple website using mostly HTML, CSS and also bootstrap, front-end framework for web design in the demonstration of the proposed system. The second part is to make the line number extractor using simple web crawler to get the required information for proposed PageRank Algorithm. Then, the PageRank algorithm is executed by using the data from web crawler. Finally, the convergence value is taken to specify the iteration count during the operation of PageRank Algorithm. The main point of proposed system is faster execution time than the original PageRank Algorithm with reduction in iteration steps.

Understanding customers helps business to provide tailored services. Clustering analysis help all business owner to gain a coherent understanding of their customers. In order to maximize the value of each customer to the business, cluster customers into segments based on their income and spending score. For this purpose, K-means is used. K-means clustering is an unsupervised learning technique which mainly deals with identifying the structure or pattern of the data. In this type of algorithms, labeled data is absent (or the dependent variable is absent). Clustering in Customer data is the process of dividing a company’s customers into groups that reflect similarity among customers in each group. A different number of clusters is tested with k-means classifier. In this experiment, up to 30 clusters is tested with the algorithm. This paper aims to improve the performance of the clustering results by measuring clustering quality with Silhouette scores. The best number of clusters is determined with Silhouette scores: the higher the better.

Analysis and Validation of Software Development In Distributed EnvironmentYin Nyein Aye, Hsu Mon Kyi, Chan Myae AyeMay 30, Software Development, CSCW, Complexity, Petri NetDownload

Software development is a collaborative process where teams of developers work together in order to complete tasks. Developers have to make decisions based on data which can be modified by other developers. To prevent wrong decisions, the system has to make sure that the data is consistent between developers and modifications on one developer are propagated to other developers. Developers can download the source code files that are stored in cloud storage server. And then they modify their source code and upload these update source code file to the cloud storage server to see others developers. However, they can read others developers’ source code file but they can’t write or modify it. Petri Net Model has been presented to compute control flow complexity for this system. The result can be shown that the nine metric values are upward trends when the number of developers increases in CSCW. This paper focuses on the complexity of proposed consistency control model by using Petri net-based representation. Moreover, an effort has been made to evaluate the control flow complexity measure in terms of Weyuker’s properties that is fulfilled by any complexity measure to be suitable for this system.

Syntax Errors Investigation System for PHP Program using Top-Down Parsing ApproachSu Su Win, Zar Zar TunMay 30, Top-Down Parsing, Predictive Parser, Left recursionDownload

Parsing is a necessary mechanism for many natural language processing applications, such as machine translation, question answering, knowledge extraction and information retrieval. In this paper, we propose the syntax investigation system which can investigate the syntax errors in the PHP program. This system takes each string from a PHP program as input and determines it as a correct message or error message by using the top down parsing approach. The predictive parser is used to construct the parse table, which determines the action of the input string based on the grammar production rules. These grammar rules were reconstructed if the left recursion rules are occurred to avoid the left recursion problem in the top down parsing approach. As a result, our system can reproduce the correct messages, error messages, and location errors. It was confirmed that our system can be useful to investigate the syntax effectively in PHP programming language.

The intention of this paper is to understand the student how to work disk scheduling policies in operating system. Nowadays, modern technology and high performance computing processors are rapidly evolved. Moreover, the speed of processor and main memory are also increased rapidly but secondary memory is still relatively slow. Thus the performances of disk I/O are also vital and many researchers are interested in schemes for improving that performance. Disk scheduling is crucial because multiple I/O requests may be by different operations and only one I/O request can be run at a time by the disk controller. It is hoped that this paper may provide an opportunity for all computer students to learn theories and pratical experience of allocating I/O device for various processes. In this research, the C programming language is used for practical interface and calculates total head movement performance of FIFO, SSTF, SCAN, and C-SCAN in disk scheduling algorithms.

Using the stochastic processes called Markov Chains are usually used in modelling many practical problems. In this paper, to predict the immediate future, the data sets for Computer University (Mandalay) are sought. The moving averages for the data are found and grouped them into five different states for the grades. Then Markov chains calculations are applied to the data to create a 5*5 transitional probability matrix. Using this transition matrix, a system of equations are solved by using Chapman-Kolmogorov Equations and found five steady states that will be the same in every row of the matrix. They are variables that represented the probability that a grade for a given year would fall into one of the five states. When this information is used, the actual data to these equations can be applied and the next grade for the near future be predicted. Near future grades using this method are able to be successfully predicted.

Memory Access Scheduling for Improving performanceYee Yee SoeSeptember 29Bandwidth, latency, memory access, DRAM and performanceDownload

The bandwidth and latency of a memory system are strongly dependent on the manner in which accesses interact with the “3-D” structure of banks, rows, and columns characteristic of contemporary DRAM chips. There is nearly an order of magnitude difference in bandwidth between successive references to different columns within a row and different rows within a bank. This paper introduces memory access scheduling, a technique that improves the performance of a memory system by reordering memory references to exploit locality within the 3-D memory structure. Conservative reordering, in which the first ready reference in a sequence is performed, improves bandwidth by 40% for traces from five media benchmarks. Aggressive reordering, in which operations are scheduled to optimize memory bandwidth, improves bandwidth by 93% for the same set of applications. Memory access scheduling is particularly important for media processors where it enables the processor to make the most efficient use of scarce memory bandwidth.

Gas leakage is a major problem with industrial sector, residential premises, and gas powered vehicles like CNG Compressed Natural Gas buses, LPG, Liquefied Petroleum Gas cars etc. One of the preventive methods to stop accidents associated with the gas leakage is to install a gas leakage detection device at vulnerable places. The primary aim of this paper is to present such a device that can automatically detect and stop gas leakage in vulnerable premises. In particular gas sensor has been used which has high sensitivity for propane (C3H8) and butane (C4H10). The system detects the leakage of the LPG using a gas sensor and uses the GSM to alert the person about the gas leakage via SMS. When the LPG concentration in the air exceeds a certain level, the gas sensor senses the gas leakage and the output of the sensor goes LOW. The detection is done by ATmega328 microcontroller and the buzzer is turned ON. The system then alerts the user by sending an SMS (Short Message Service) to the programmed mobile number.

This paper presents a new text to text data hiding steganography using arbitrary two bits including least significant bits. It also presents a novel algorithm to hide a large amount of text in cover text file without affecting the cover format, meaning and font types, by using position file in which all indexes are stored according to the secret message with respect to the cover text file. The size of secret message and cover text file can vary the processing time, while extracting secret message back from cover files using position file. Unlimited amount of secret message can be hidden in a cover text file because the indexes are used as much time as we want with round loop function. But the more the size of secret message, the more the size of position file. In this research work, various secret message and cover files are used to analysis of extracting time. This proposed system is implemented by using MatLab Programming Language.

Initiation of Blockchain Technology based Open Framework for e-Government Development in MyanmarThinn Thu NaingJune-24Blockchain Technology, e-Government services, Smart Contract system, Cryptocurrency, Secured Distributed Ledger SystemDownload

In Myanmar, necessary e-government services are not fully implementing yet. Several challenges and issues are still facing in e-government developments such as the new trend of technology, legal enforcement, and individual awareness. Currently, some ministries and institutions in Myanmar are implementing their own systems independently. In the last decade, infrastructure and software development for the e-government system has invested. However, the dedicated open framework for e-government services still needs to consider. The author proposes an open framework called “Blockchain-based Open Framework for e-Government Services” in this paper. That will be helpful for the standard implementation of Myanmar e-government services efficiently and effectively. Blockchain technology is one of the megatrends for recent years. It is potentially a revolutionary means of secure and transparent data sharing and processing in a wide variety of sectors. The important concept of Blockchain technology is a combination of secured distributed ledger, cryptocurrency (or) bitcoin and smart contract system. That concept is very appropriate at: (i) creating trusted and secured information processing for large and heterogeneous sets of stakeholders; (ii) creating trusted audit trails of information; (iii) creating robustness and cost-saving data processing platform. The government agencies around the world are looking forward to Blockchain technology for secured e-government services efficiently and effectively. The proposed framework would consist of five layers. Development platform Layer (Layer 1) is the interface layer for application development. There are several e-Government applications depends on the services categories of G2G, G2C, G2B, and G2EservicesThe most e-government services activate depends on the legal law and regulations of individual government. Blockchain-based Services Layer (Layer 2) provides core services of cryptocurrency, blocker service, shared distributed ledger, smart contract, auditing, identification, verification, cybersecurity, payment, authentication, and authorization. Data standardization is the most important part of the e-government system. All data of ministries are storing in heterogeneous and distributed forms. AI-based machine learning algorithms, database methodologies, and standardization methods are involved in Data Standardization and Distribution Layer (Layer 3). Data Storage Service Layer (Layer 4) and Secure and Distributed Infrastructure Layer (Layer 5) are underlying layers for data center services, storage service, distributed computing services, and secure protocol services. The intended outcomes of the proposed framework would be (i) ensure the secure, reliable, and robustness services (ii) support unique standardization for data between all institutions and ministries (iii) provide interoperability and efficiency for collaborative processes between sub-systems.

Intelligent Traffic Prediction by Multi-sensor Fusion using Multi-threaded Machine LearningSwe Swe Aung, Itaru Nagayama, Shiro TamakiDecemberIntelligent transportation system, K-nearest neighbor, Naïve bayesDownload

Estimation and analysis of traffic jams play a vital role in an intelligent transportation system and advances safety in the transportation system as well as mobility and optimization of environmental impact. For these reasons, many researchers currently mainly focus on the brilliant machine learning-based prediction approaches for traffic prediction systems. This paper primarily addresses the analysis and comparison of prediction accuracy between two machine learning algorithms: Naïve Bayes and K-Nearest Neighbor (K-NN). Based on the fact that optimized estimation accuracy of these methods mainly depends on a large amount of recounted data and that they require much time to compute the same function heuristically for each action, we propose an approach that applies multi-threading to these heuristic methods. It is obvious that the greater the amount of historical data, the more processing time is necessary. For a real-time system, operational response time is vital, and the proposed system also focuses on the time complexity cost as well as computational complexity. It is experimentally confirmed that K-NN does much better than Naïve Bayes, not only in prediction accuracy but also in processing time. Multithreading- based K-NN could compute four times faster than classical K-NN, whereas multithreading – based Naïve Bayes could process only twice as fast as classical Bayes.
