Cost-effective large-scale real-time video broadcasting technology has remained out of reach despite tremendous efforts and technical innovations over the past two decades. Introduction of Internet Protocol (IP) Multicast and Unicast architecture were earlier attempts to tackle this problem. But serious complications regarding scalability and difficult deployment have dogged these attempts. In recent years peer-to-peer (P2P) based broadcast has emerged as a promising technique because this paradigm brings many unique advantages such as cost-effectiveness, easy deployment, scalability, resilience. While P2P applications such as file download and voice-over-IP have gained much popularity, video conferencing is still in its early stages. The aim of this paper is to introduce P2P VIDEO CONFERENCING SYSTEM BASED ON Web Real Time Communication (WebRTC). WebRTC provides the opportunity of establishing P2P connections within web, without additional plugins and third party software. This paper presents a scalable live video conferencing architecture designed based on WebRTC. Our experiments show that WebRTC is a capable building block for scalable live video conferencing within a web browser.

In this paper, single CZTSe layer and stacked layer of CZTS and CZTSe have been optimized as absorber layers in thin film solar cell and the variation of cell performance was observed. CZTSe layer was optimized by varying thickness, carrier density and defect density and obtained Jsc of 27.87 mAcm-2, Voc of 0.702V, fill factor of 65.41% and efficiency of 12.79%. By varying the thickness and carrier density of both CZTS and CZTSe together, solar cell was optimized with stacked layer of CZTS and CZTSe. Solar cell with the stacked absorber layer was found to have better cell performance among different CZTS-based solar cells with Jsc of 29.23 mAcm−2, Voc of 1.1188 V, FF of 71.70% and efficiency of 23.45%.

In this paper, a nonlinear adaptive controller for regulating the grid of a current source inverter (CSI) based three-phase grid-connected photovoltaic (PV) system is proposed. The proposed control structure is composed with an outer control loop-responsible for controlling the DC-side inductor current and the inner current control loop-responsible for controlling injected current into the utility grid. The proposed adaptive controller is designed recursively by considering external disturbances within the system and these unknown external disturbances are estimated through the adaption laws. The overall stability of the whole CSI based three-phase grid-connected PV system is verified by formulating the control Lyapunov functions (CLFs) at different stages throughout the design process of the proposed controller. Finally, the performance of the designed controller is tested on a similar CSI based three-phase grid-connected PV system under different atmospheric conditions. Simulation results demonstrate that the proposed control scheme can effectively meet the desired control objectives as compared to the existing controller in terms of settling time and power quality.

The vector representation of Bengali words using word2vec model (Mikolov et al. (2013)) plays an important role in Bengali sentiment classification. It is observed that the words that are from same context stay closer in the vector space of word2vec model and they are more similar than other words. In this article, a new approach of sentiment classification of Bengali comments with word2vec and Sentiment extraction of words are presented. Combining the results of word2vec word co-occurrence score with the sentiment polarity score of the words, the accuracy obtained is 75.5%.

This paper introduces a detailed study of minority carrier lifetime dependence into switching power loss calculation of Non-Punch through (NPT) Insulated Gate Bipolar Transistor (IGBT). Parabolic approximation has been used for modeling the minority carrier concentration within the base. In virtue of this new expression an analytical model has been developed for transient turn-off voltage and current of IGBT in all minority carrier lifetime conditions. Better consistency with the practical results has been found for this parabolic model compared to the previously used linear model. Finally, the implications of carrier lifetime dependence on the calculation of switching power loss have been discussed.

Document processing implies processing of documents in a way that the information of the documents can be rendered, retrieved or presented in an understandable way. Survey document processing is the task of analyzing survey documents to obtain people's opinion about product or services. Nowadays, survey is conducted in two different forms. One is online survey and another is using printed documents. The survey that is conducted using printed documents is difficult to process due to the lack of automated processing tools for such types of documents. Considering this fact, in this paper we present a framework for efficient processing of survey documents. Our system works in two major steps. First, we recognize the answers of the users' in each document. Then, we analyze the answers considering all the documents to produce final survey results. We have evaluated our system with sufficient number of survey documents and found that our system can perform almost accurate analysis of survey documents.

This work reports on developing an analytical pinch-off voltage model for the pocket implanted nano scale n-MOSFETs based on an asymmetric linear pocket profile at the source side under the gate of the device. Straight line approximated equation is used to simulate the pocket profile from the source towards the drain along the gate length at the surface of the MOS device. The effective doping concentration is derived for the whole gate length and is incorporated in the pinch-off voltage model that is obtained from the strong inversion charge expression at the surface. Then the pinch-off voltage is simulated for various drain and gate biases as well as for various device parameters. To observe the model validity, inversion charge profile, surface potential at various points along the channel, drain current vs. drain voltage curve is plotted for various gate biases by incorporating this effective channel doping concentration as well as the developed pinch-off voltage model. The simulation results show that the developed pinch-off voltage model can be used to study, simulate and characterize the pocket implanted ULSI devices.

This paper proposes a grid connected PV-Ocean wave hybrid renewable energy (RE) power generation system with battery as an energy storage device. Ocean wave conversion system is designed by combining an oscillating wave column (OWC) converter based wave chamber, which fed power to a wave turbine that is coupled to a permanent magnet synchronous generator to generate ocean wave power. In order to build PV array, total five KOYCERA KC85T-87W PV model is designed in MATLAB and all the models are connected in series in combination with one another. To maintain constant voltage at DC link capacitor storage device battery is used. A proportional integral (PI) controller based Buck-Boost converter is used to control the charging and discharging state of battery to maintain constant DC link voltage. A three-phase voltage source inverter (VSI) is designed to integrate the proposed hybrid system with the grid. Simulation using MATLAB/Simulink has been conducted to evaluate the performance of the system.

The ubiquitous services of wireless communication networks are growing rapidly by the development of wireless communication technologies. While a user is roaming from one cell to another cell, an intelligent decision mechanism and network selection is extremely crucial to maintain the quality of service (QoS) during handover. Handover decision must be made precisely to avoid any unnecessary phenomenon like ping-pong, corner effect, call blocking, and call dropping etc. This work considered service types like voice, video, and data and their QoS requirements for handover decision using fuzzy logic in heterogeneous network environment. Service is an important factor for the users and particular service requires respective QoS. This paper provides all the cases of handover decisions between macrocell and femtocell networks considering service type. The proposed system models regarding these handover decisions using fuzzy logic considering several input parameters e.g. received signal strength indicator (RSSI), data rate, user's velocity, and interference level (signal-to-noise plus interference ratio) to make handover from femtocell to macrocell, macrocell to femtocell or femtocell to femtocell. The performance of different parameters are shown based on service type are analyzed.
