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%.

Data mining is also known as knowledge discovery from huge data sets. Potential useful information also comes out from data set through data mining. This outcome is important for existing data sets and for further analysis, development and planning. This paper put a light on performance evaluation, based on the correct and incorrect instances of data classification using different classification algorithm. The paper sets out to make comparative evaluation of classifiers Naive Bayes, Multilayer Perception, J48 Decision Tree and IBK in the context of household datasets to maximize true positive rate and minimize false positive rate of defaulters rather than achieving only higher classification accuracy using WEKA tool. This paper also investigates and analyzes the existing raw data improved cook stoves (ICS) from different household information in Bangladesh; and also expedites Association Rule to extract some important information that can be helpful for future deployment, analysis and planning for sustaining efficient improve cook stove (ICS) program.

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.

In modern power systems, long transmission lines coupled with fast-growing load demand factor have resulted in a more stressed system than ever before. This paper is aimed at static voltage stability analysis(VSA) of IEEE-14 bus standard test case for weakest region exploration using conventional P-V and Q-V curve methods for investigating voltage unstable regions, predicting and preventing system blackouts. Furthermore, the static capacitor, synchronous condenser and STATCOM have been used for effective voltage restoration and regulation purposes. Hence the power grid can effectively manage and provide electricity reliably, safely and economically to consumers. Power World Simulator environment has been used for performance analysis.

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%.

Now a days lightning performance of telecommunication tower is an important issue of major interest for wireless communication service provider utility companies. Lightning is the most important and severe external transient phenomenon that can cause dangerous over voltages on transmission line, damages of sophisticated electronic equipment, terrible induced high voltages as well as electromagnetic compatibility problems on power transmission and telecommunication system. Telecommunication tower suited on the roof of multistoried building can be easily hit by direct lightning strike and telecommunication tower can cause dangerous overvoltages, which can result in malfunction of the sensitive equipment as well as dangerous step and touch voltages then finally hampered the communication system connected to the tower. This paper demonstrates the lightning surge response and effect of direct stroke for typical mobile phone tower suited on multistoried building roof. The simulation of the electromagnetic transient process, caused from the lightning stroke on the different portion of the tower and building have been carried out over the usage of the ATP Draw (Alternative Transient Program) software tool. ATP Draw is a mouse-driven, graphical preprocessor to the ATP version of the Electromagnetic Transients Program (EMTP) on the Microsoft Windows platform. The Alternative Transients Program (ATP) is considered to be one of the most widely used universal program in electric power systems for digital simulation of transient phenomena of electromagnetic as well as electromechanical nature. The key focus of the study has been the assessment of the surge characteristics of the different portion of the structure under the effect of a lightning sources. Surge impedance, Voltage and currents at different portion of this tower are evaluated to observe lightning phenomena for designing of protective equipment to save the sensitive electronic parts and equipment contains tower and building.

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.

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.

In modern civilization, the solar energy as renewable energy is chosen for the generation of the clean and green energy which is very reliable in response of sustainable development. The SnS is a binary semiconductor compound which has very favourable optoelectronic properties for lost cost thin film solar cell. Therefore, the researchers have great attention to investigate the ultra-thin SnS solar cell. In this research work, the deep level defects on the performance of SnS solar cells with Bismuth Sulfide (Bi2S3) as window layer material was carried out by numerical analysis using SCAPS 2802 simulator. In the proposed cell, the SnS absorber layer was reduced that minimized the cost, saving process time and energy required for fabrication. In this study, it was found that the feasibility of this proposed ultra thin SnS solar cells and showed higher efficiency of 20.05 % (Jsc = 36.61 mA/cm2, FF = 0.614, Voc = 0.89 V). Consequently, it has been investigated the thermal stability of the SnS solar cell to explore the hidden potentiality of absorber layer.

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.
