Massive Open Online Courses (MOOC) is a trending phenomenon in online education. Number of participants in a MOOC and the number of MOOCs by platforms and courses are appearing to be increasing at a tremendous level. Although MOOC found to be the “buzz” word, latest reports claim that the hype of the MOOC is fading. One reason to this is because many MOOCs offered and created despite of evaluating the effectiveness of it. Therefore the qualities of MOOCs are under criticism. It is essential to seek possible solutions to balance the learner goal while offering a quality service. Working towards the direction, this literature review focuses on past researches carried out in identifying the success factors, best practices, and effectiveness of a MOOC. We focused literature published between 2012 and 2015 and found significantly less number of empirical evidence in discovering MOOC quality factors. Out of 4745 peer reviewed publications which met with the search terms, only 26 literatures found to produce highly relevant in deciding a quality of a MOOC. Out the 26 literatures, only 3 provided a quality dimensions with empirical evidence and 7 provided with proposal frameworks based on past literature. We discuss the concerns arising from the review and identify issues including lack of evidence in identifying the critical success factors, absence of social interactions, networking, anthropological and ethnographic view in determining a quality MOOC.

Among many available types of robots, bilateral systems are widely applicable and famous. There are so many master designs that are readily available to support bilateral systems. Among them, the Joystick (Remote Control), Electromyography, Voice Control, Haptic (Mechanical and Touch Sensitive), Gesture (Hand Gesture, Body Gesture and Eye Gaze) and BCI (Brain Control Interface) are available. This study is to reveal the competitiveness of available master designs for assessing the applicability in bilateral system design for an epidemic environment. A literature survey of International research publications for bilateral medical systems for last few decades was performed to reveal the applicability, controllability (in operation), complexity (of the device), response, reliability and safety of the available master designs. Remote Controlling and Electromyography based technologies are found to be the oldest and established techniques and Haptic is in the middle stage. These conventional systems consist their own disadvantages and control issues. To overcome those issues with the emerging of vision attentive systems the gesture based designs were invented and today it has become widely applicable and well known in research. Also BCI and Voice Control based techniques are in research level and rapidly developing. The assessment of these systems is performed towards a designing of a bilateral system for an epidemic environment which is cost effective, reliable, repetitive and operator skill independent. It is found with the present technology, Gesture based controlling systems are more likely to satisfy the design requirements than other conventional and modern systems and will be widely applicable within next few decades by overcoming its minor issues.

Music ensemble is a must in either music learning or music performance. The experience trying to play with others well helps learner a lot. However, players do not often have other players to play with together when they practice on their own. Time and distance restrict musicians to have much practice. With the advent of Web 2.0, Internet has been the best way of sharing and interchanging multimedia content. If music ensemble and network can be integrated in a platform which supports information sharing and collaborating through easy manipulation and technology of synchronization, it will be a wonderful system. Our research focuses on the issue of video synchronization on music ensemble. There are two kinds of music scores which beginning is tutti or not. If the score is tutti at the beginning, sound detection provided by Firefox Audio API is used to find the onset time automatically and a music ensemble is created. If the score is non-tutti at the beginning, automatic sound detection is not enough and users' manipulation is required. Then the system will calculate the correct initial time of every video and music can be synchronized well. We hope the system can enhance the fun of music ensemble for music players. The novel application can solve the restriction of time and remote distance and make music ensemble more flexible and practical.

The results of this paper based on analysis of design patch antenna with minimum dimensions and permittivity acquirable that produces a maximum power output. Since RF (Radio Frequency) energy harvesting is a recurring theme which enormously effective and applicable in occasions where remote charging and wireless power transmission take place. The potential use of RF energy was investigated experimentally. The aim of this work is to investigate the power levels that can be harvested from the air and processed to achieve the energy levels that are sufficient to charge low power electronic circuits. An RF collection system has been specifically designed, constructed, and shown to successfully collect enough energy to power circuits. For an equivalent incident signal the circuit can produce required voltage across load. This voltage can be used to power low power sensors in sensor networks ultimately to replace the batteries.

In order to minimize the processing time and maintain the color palette, simplify the processing of, our research category the available colors into primary color the colors from the photographic processing by Error Diffusion, the research will use the color space HSL as color model to build the error diffusion application which designed for available and limited colors to making fine arts such as tile mosaic art or cross-stitch art. Those commonly used image formats: BMP, JPG, GIF, PNG; are raster images which data are saved in pixel. If we reduce colors from those four image format using the error diffusion, the system will consume lots of running time and generate too many colors. In order to reduce processing time and colors, the research will use HSL. HSL were widely adopted as a standard alternative to RGB due to the low processing running time, and their close to artist's color theory and better image edge detection. This research will compare those result images generated by Floyd and Steinberg error diffusion with two color spaces HSL and RGB.

In this paper, we propose a skeleton and gesture-based user authentication system using depth cameras. When a user would like to register, our system will capture a user's skeleton and gesture information and store it into the database. When authenticating a user, our system will capture the user's skeleton and gesture information and compare it with the data stored in the database. Experimental results show that the combined use of skeleton and behavioral information is able to improve the accuracy of user authentication.

In the last decades, along with the continuously evolving of the Internet Protocol-based network, numerous Internet programs that have played critical roles in the current technological era are being developed inclusive of interactive applications. Nevertheless, the transmission performance and user experience of these instant services that require high bandwidth or low latency may suffer when serious traffic congestion occurs. In this paper, a QoS management system with a dynamic routing algorithm, based on a software-defined networking architecture, is implemented. The purpose of the system is to generate an optimal route with minimum cost based on real-time monitored statistics and the cost model. The system is also integrated with a flow classification engine based on machine learning algorithms to enable the application identification thus providing a bandwidth management mechanism that can enforce rate-limit policies for each application with different priorities under traffic congestion. Experimental results show that the proposed algorithm can provide excellent QoS with little overhead, where the rate-limit policies can be implemented in one to several seconds for different applications through the bandwidth management mechanism.

Effectiveness in eLearning is identified as meeting the users' learning goals. It has been the subject of many researches which have led to a variety of dimensions and factors affecting it. However with the latest disruption of educational technology, MOOC has changed the perceptions of eLearning by taking eLearning to a new direction. Hence effectiveness dimensions & factors revealed before the introduction of MOOC required revising in order to cater to the new demands of eLearning in MOOC. At the same time there are many MOOC platforms introduced to the market leading to a potential issue of quality as not all the MOOCs provide effective results. Users are required to identify the effectiveness of MOOC. In searching for the solution to above problem, our research revealed a 10 dimensional framework for analyzing the effectiveness of eLearning in MOOC. Those are namely interactivity, pedagogy, collaboration, usability, network of opportunity, motivation, technology, content, support for learner and assessment. The framework was built using an instrument and tested with a sample size of 121 MOOC participants. Empirical results demonstrated that the instrument is within the acceptable range of verification and validation values. Therefore the 10 dimensional effectiveness framework assists as a benchmark for MOOC stakeholders.

Automatic text extraction from number plates is used in most of the countries in present. In this paper a semiautomatic text extraction from Sri Lankan vehicle number plates is presented. There are several number plate types currently available in Sri Lanka. First a set of template was created based on the font used in the number plates for all the English letters and numbers. Number plate first corrected as can be seen from a camera situated in front of the camera. Then the area of the numbers is extracted. Texts and numbers are then separated in to separate images. Finally separated texts and numbers are matched with the original template created using template matching. A data set consisted of 93 number plates is used to demonstrate the usability of the proposed method.

Currently, people obtained housing information from relatives, friends, sale representatives from model home, Realty networks, or government. It is difficult to get the housing-related information from these resources and hard to compare. Therefore, we proposed a public inquiry website called Housing Price Analysis using information from public websites to do statistical analyses based on the total ratio of "average value" and "standard deviation". People can use this website to get better understanding of price trend in certain area. This website will compare all records on public realty websites and government system based on same area with similar size of houses, number of rooms, age of house, etc. By using this system, users can get better understanding the trend of housing prices.
