this paper proposes a simple message passing detector with QR-decomposition for multi-input multi-output ( MIMO) systems. Our message passing algorithm exploits the structure of QR-decomposed received signals and achieves optimum maximum likelihood ( ML) detection with less complexity. computer simulations confirm the superior performance of our proposed approach to conventional message passing techniques such as belief propagation ( BP).

It is the need of an era to store and process big data and its applications. To process these applications, it is inevitable to use heterogeneous distributed computing systems (HeDCS). the heterogeneous distributed systems facilitate scalability, an essential characteristic for big data processing. However, to implement the scalable model, it is essential to handle performance, efficiency, optimal resource utilization and several other key constraints. Scheduling algorithms play a vital role in achieving better performance and high throughput in heterogeneous distributed computing systems. Hence, selection of a proper scheduling algorithm, for the specific application, becomes a critical task. Selection of an appropriate scheduling algorithm in heterogeneous distributed computing systems require the consideration of various parameters like scheduling type, multi-core processors, and heterogeneity. the paper discusses broadly the hierarchical classification of scheduling algorithms implemented in heterogeneous distributed computing systems and presents a comparative study of these algorithms, thus providing an insight into the significance of various parameters that play a role in the selection of a scheduling algorithm.

Photovoltaic (PV) systems are growing in demand due to the recent drop in prices of the solid state components. However, the quality of the output of the PV systems are still lacking behind and this is a major problem while connecting the system to the grid. Inverters being the brains of a solar PV system need to be made smarter and better. Multi-level inverters are one of the most popular types of inverters for grid-connected PV systems due to the higher quality output they can produce than other inverters. One of the key features they provide is the minimization of total harmonic distortion (thD) and electromagnetic interference which tackles leakage current issue. So, in this paper a new five-level inverter topology for grid-tie PV is proposed which is controlled using a new voltage controller that ensures higher efficiency while enhancing the stability of the system. the suggested closed loop voltage controller method additionally provides the ability to provide constant or adjustable voltage to the grid. In this proposed topology the voltage controller enables the PV system to provide high quality power to the grid which is vastly important. To validate the accuracy of the theoretical analysis, the control technique was applied to the existing multi-level inverter topology and then has been simulated in MATLAB/Simulink software. Moreover the five-level output provides a much better output and better PF then other existing topologies. © 2018 IEEE.

In the walk of Advanced Driving Assistance systems (ADAS), Intelligent Driving and Traffic safety, Object detection plays a crucial role in the upcoming genesis of self-governing vehicles. Traditional computer vision and machine learning advances for object detection confront challenges against the difficult image backgrounds and environment conditions like sunlight effects, barricades and occlusions. In this paper, Single Shot Detector (SSD), Faster Region Convolutional Neural Network (Faster RCNN) and You Only Look Once (YOLOv2) deep learning architectures are compared by applying distinct pretrained Convolutional Neural Network (CNN) models. Experiments have been organized in a wide range to attain distinct models of Faster RCNN, SSD and YOLOv2 through appropriate modification in algorithms and parameters tuning. In this work, SSD, Faster RCNN and YOLOv2 are trained for 5 different object classes of traffic signs and their outcomes are evaluated. Traditional Evaluation parameters: mAp(mean Average precision-Precision, Recall and IoU) and FPS(Frames per second) are run-down to analyze the accuracy and speed of the algorithms. On analyzing, the accuracy of YOLOv2 outperforms Faster RCNN and SSD by 3.5% and 21% respectively. Also, YOLOv2 learned 3 times speedy than Faster RCNN with increased accuracy.

In this paper we propose the practical application of multimodal conversational interfaces to develop advanced mobile learning applications. Our proposal integrates features of Android APIs on a modular architecture that emphasizes interaction management and context-awareness to build user-adapted, robust and maintainable (mobile learning) m-learning applications. We have applied the proposed framework to develop a mobile learning application that improves users' interaction to solve practical educative exercises, promotes autonomous learning and self-assessment, personalizes the selection of recommended learning activities considering the student's preferences and their previous uses, and allows the provision of immediate feedback by means of the automatic assessment.

In recent years, Virtual Learning has gained wide popularity among the Higher Education Institutions (HEIs) to promote holistic education. Reviews have proven that Virtual Learning has proliferated over the years and it has created a dynamic learning culture among the 21st Century learners. these young learners from the digital age have different learning styles and vernaculars as they are much more diverse. It is also noted that it is challenging to keep these learners engaged in learning due to those differences. therefore, it is vital to identify a learning tool that caters to these young learners from a diverse background and simultaneously optimize their learning satisfaction. To address these momentous issues, this research study aims to identify the design factors or specifications of a Virtual Agent (VA) deployed in the Virtual Learning Environment (VLE) to maximize learner’s satisfaction. In this exploratory study, the researchers have adapted Kansei Engineering (KE) approach that uses the quantitative analysis to identify the design factors of Virtual Agent. the respondents are undergraduate students from a HEI in Malaysia (N=107). the findings suggest that KE modus operandi had successfully paved the way for an effective design of VA that has high aesthetic value and identified attractiveness and expertness as key factors in VA design. © Springer Nature Singapore Pte Ltd. 2018.

the ASEAN Economic Community (AEC) encourages Micro, Small and Medium Enterprises (MSMEs) to heighten their competitiveness by applying information and technology (ICT) solutions. However, MSMEs are faced with challenges, specifically, the lack of ability to be globally competitive, to develop market driven product based on customer needs, and their inability to fully leverage the benefits provided by the digital and internet economy. Today, cloud computing can be a promising alternative for MSMEs to exploit the benefits of technology. Cloud computing, particularly cloud ERP (or software as a service) has created positive impact to the operations of global enterprises. For us to better understand the factors that will influence the adoption/rejection of Cloud ERP for MSMEs, it will be grounded on Technological, Organizational, Environmental Framework and Salim’s Process-View Approach for the technology adoption process. While majority of research are descriptive studies of Cloud ERP and is viewed from a vendor’s perspective, this study will investigate the factors that influence the acceptance/rejection of Cloud ERP for MSMEs, particularly the key decision makers. this research study will use both quantitative and qualitative approach in the analysis of data. this mixed-method approach has gained popularity among IS researchers to develop novel theoretical perspective in information research. © PACIS 2017.
