The main objective of the paper is that it deals with the designing of a Photovoltaic array connected to a Brushless DC (BLDC) motor using an easy and feasible Maximum Power Point Tracking (MPPT) algorithm. At present, Photovoltaic energy is one of the most vital energy resources in electrical power applications around the world. It is essential to operate the Photovoltaic (PV) system at the Maximum Power Point (MPP) so that maximum power can be secured from the solar panel because the output power from the PV arrays is sensitive to temperature changes and solar irradiance. In this paper, the Perturb and Observe (P&O) algorithm, a buck converter and a three phase inverter are used which are modelled in Simulink tool of MATLAB.

A novel structure meander line antenna is investigated in this paper for anatomically realistic human head phantom of implantable Brain Machine Interference (BMI) applications. Head phantoms imitating electrical properties of brain tissues and their anatomical configuration are highly requisited for verification of numerous biomedical devices. To approve the analysis of implantable antennas more accurately, simulation is examined using anatomical realistic human head phantom. The main integrity of this antenna specifies to its subtle dimension, flexibility and subordinate thickness that makes it perfectly applicable for implementing inside human head phantom operating ultra-wideband frequency spectrum. Meander line technique is imposed in implantable scenarios. Dimension of the antenna structure is (15.2 * 8.8 * 0.8) mm3, where Roger RO3035 is selected as the substrate material. Copper is selected for Patch material. And the antenna is encapsulated by silicon material for maintaining biocompatibility. Crucial parameters are analyzed such as S11 parameter, Radiation pattern, VSWR, Gain, Efficiency, Directivity, SAR values of the proposed antenna for anatomical realistic human head phantom. This improved design of MLA configuration reducing Specific absorption rate for safety concerns.

This project focused on installing of lightning protection system and its equipment’s. This project was implanted for both shade building and full building with a rooftop. The objective of replacing air-terminal is to catch the strike of lightning and conveyed the current through the down conductor to earth pit. The whole process was followed by BNBC-2006 to make sure a structure or building safe from lightning. As it is essential for factories and industries to take protective action to make ensure the industrial electrical equipment’s, as well as the life of the workers, do work there. To monitor the working process, the Lightning counter device was used to detect how many strikes it caught. The risk assessment of lightning protection system has been done considering 7 index factor (A, B, C, D, E, F, and G), which recommended LPS is essential by calculating total index figure. The diameter of air-terminal was selected as 8 mm and air terminal height was varied 500 mm, 700 mm, 800 mm, 2 meters and 2.5 meters. Therefore, adopting the meshing technology following the BNBC-2006 can be the challenging and easily adaptable for the perspective of Bangladesh.

The Integrated Smart Parking System (ISPS) incorporates detection of empty parking spot and inappropriate parking, finds the available and different kind of parking spaces in various zones and suggest the most shortest way to reach the location. The ISPS mainly focuses on minimizing the time and maintaining a strategic distance from unnecessary traveling. There are lots of smart parking systems and a greater part of the solutions are following the conventional design approach focusing on a single parking center. However, existing single parking concentrating approached framework can’t satisfy the prerequisites of the incorporated smart parking system. In this study, for ISPS the structure has been defined with the utilization of best innovations. The ISPS can help the users to search the unoccupied spaces in the user-specific area within a very short time and also can suggest the nearest location from user destination. Additionally, ISPS supports the users with automated management of parking spaces and cares about fuel utilization.

IEC 61850 standard has been used in recent years for modern sub-station automation system (SAS) which enabled the interoperability among communication devices from different vendors. However, it is not specified in the IEC standard for any certain type of communication architecture for a certain type of substation. Certainly, it demands zero points of failure with a particular time limit of transferring the message. So, it is very important to find a comprehensive analysis of reliability and availability of the communication architectures for modern digital SASs. In this paper, a mathematical approach is used to analyze the reliability and availability in detail and finally propose a suitable design for efficient operation. For simulation, an Optimized Network Engineering Tool (OPNET) has been used.

This paper describes a new window function which is adjustable as well as enriched with linear phase response. Using a simple regulator, the new window can be altered according to need. The proposed window function is a combination of a sine and cosine function. The window function has been compared with Kaiser, Gaussian, Tukey and a window proposed by Rakshit et el. and their filters. The simulation results show that the output of the designed FIR low-pass filters reflects higher SNR value for the presented filter which is 3.4227. Moreover, the presented window is showing 2.78 dB higher sidelobe roll-off ratio than the Kaiser window, 2.18 dB more than the Tukey window and 1.84 dB greater than the Gaussian window-based FIR filter.

Epileptic seizure is a neurological disorder characterized by abnormal synchronous discharge of the neuronal activities in the brain structures. These abnormal electrical activities can be recorded via multi-channel electroencephalography (EEG) signals placed on the scalp of the brain. Usually, these signals, recorded from this EEG device, are interpreted by the neurologist which require their availability and it is very time consuming especially for long duration signals. This study presents a fully automatic system for the detection of seizure from non-seizure signals. Firstly, it pre-processes the signal to remove noise and artefacts from the raw-EEG signals and then extracts features. Features are extracted from time-domain, spectral domain, wavelet domain. In addition, connectivity and entropy based feature have also been extracted. After that, prominent features have been selected from this large feature set by a multi-objective evolutionary algorithm and finally, Support Vector Machine (SVM) classifier has been used for classification. A Bayesian optimization algorithm has been used to optimize the hyper-parameters of SVM. Linear Discriminant Analysis (LDA) and Quadratic Linear Discriminant Analysis (QLDA) have also been used for comparison. The proposed system is tested on a publicly available CHB-MIT database and results show the significance of the proposed system. The distinguished accuracy of the classifier is 76.41%, 80.79% and 97.05% in LDA, QLDA and SVM, respectively.

In this paper the performance of Microcells was analyzed using MATLAB simulation to create a real-life scenario of radio-waves signals propagating in three different environments: urban, suburban and rural area to find out the signal loss, and from that it is understood which areas are best suited for Microcells. This was achieved using several propagation models of both empirical and deterministic types for comparison purposes like Winner II model, Stanford University Interim (SUI) model, and Ericsson 9999. 1800 MHZ frequency band is considered, as Micro cell works best at this frequency range. For corresponding models, their mathematical model is used to find the Estimated maximum allowable path loss and model loss for 4G LTE process. The results are compared, and it is concluded based on simulation results that Microcells give the best result for Winner II model and poor result for Ericsson 9999 model, while real life results may differ. Mobile phone system like PHS and DECT are using Microcell which covers limited area like mall, hotel or transportation hub.
本文利用MATLAB仿真对Microcells的性能进行了分析，模拟了无线电波信号在城市、郊区和农村三种不同环境下传播的真实场景，找出了信号的损耗，从而了解了哪些区域最适合Microcells。为了进行比较，我们使用了几个经验和确定性类型的传播模型，如Winner II模型、Stanford University Interim (SUI)模型和Ericsson 9999。考虑1800兆赫频带，因为Micro cell在这个频率范围内工作得最好。对于相应的模型，利用其数学模型求出4G LTE过程的估计最大允许路径损耗和模型损耗。仿真结果表明，Microcells在Winner II模型中效果最好，在Ericsson 9999模型中效果较差，但实际结果可能存在差异。移动电话系统，如小灵通和DECT使用Microcell，覆盖有限的区域，如商场，酒店或交通枢纽。
