This article treats the gate driver system for IGBT modules in Medium-Voltage (MV) applications. The study focuses principally on two functions of an IGBT gate driver: an impulse signal transmission and a power transmission. For each function, the suitable topology is proposed. Then, for safety and device's protection reason, all gate driver functions must sustain the high and very high galvanic insulation voltage capabilities. For low-cost design, the insulation system can be achieved with the help of the insulating material in a pot core planar transformer. Therefore, for each function, the optimized design of a pot-core transformer and its associated electronics components is performed with the help of a virtual prototyping tool (a genetic algorithm: GA code in MATLABTM). The first section focuses on optimization design of a selected topology for an impulse signal transmission function. A bi-objective (maximize the output voltage vout and minimize the input current imos) problem of this function that leads to a Pareto front is presented. Several Pareto fronts’ results are obtained assuming different insulation layers thickness. The second part focuses on optimization design of a selected topology for a power transmission function. Maximize the converter efficiency (ηcon) and minimize the output power (Pout) are considered as a bi-objective. Thus, numerous Pareto fronts’ results are achieved for a few different insulation thicknesses. Finally, the prototype of a single channel IGBT gate driver is invented to validate the proposed design.

The demand for electricity in remote rural areas is a major obstacle to their development. The extension of the grid network to remote rural areas has been identified as a difficult topography for complex constructions and enormous investments. The development of off-grid renewable energy generation technologies offers the opportunity for tackling these challenges. This study provides a techno-economic feasibility analysis of an off-grid hybrid renewable energy system for a rural village of district Kech, Balochistan, Pakistan. The proposed hybrid system integrates the different combinations of the wind turbine, solar PV modules, and battery backups to meet the required electric load demand. The hybrid system is modeled and optimized through a powerful simulation software Hybrid Optimized Model for Electric Renewable (HOMER-Pro). The optimized configuration of the hybrid system consists of wind turbines (12kW), solar PV (103kW), 224 lead-acid batteries (72.4Ah each), and 29.1 kW converters. The simulation results show that the proposed system can meet the power requirements of 197.74kWh/day primary demand load with 27.87kW peak load. This system configuration has the Net Present Cost (NPC) of $127,345 and Cost of Energy (COE) of 0.137$/kWh with a 100% renewable fraction. Furthermore, the results of the present study are compared with the literature and have resulted in a cost-effective hybrid renewable energy system with a low COE.

In this fast-changing world, Academic library users seem to have less time for accumulating reading and learning materials. Reading the whole book, articles, and sourcing information traditionally has become a problem. It has become essential for library professionals to provide information to the users within the shortest possible time through electronic resources using the appropriate information and communication technologies [ICTs]. Electronic publishing has become common in knowledge acquisition and it is complimenting printed versions. Besides the web-based resources, there is also much non-network electronic publishing such as Encyclopedias/ Dictionaries/ Directories in CD Rom and DVD, technical and reference publications accessible through mobile phones and other electronic devices. This paper discusses the impact of electronic publishing on academic library services to its users. It conceptualizes the term electronic publishing, identifies the impact of electronic publishing on library services as user satisfaction, mobility and flexibility of information sources, encouraging collaborative work, maintenance and accuracy of publishing works, increased information sources in the library collection, adds value to library services, etc. The paper outlined some benefits and problems of electronic publishing in today's library services. It also discussed the findings observed. The paper is an opinion paper; it investigates the topic using observation research method and available library resources. The significance of this study shows that electronic publishing has come to stay. It will continue to complement the traditional method of library services even become more preferred and relevant in information resources and services rendered in academic libraries.

This study aims to analyze the effect of embedding HVDC (High Voltage Direct Current) on the voltage stability and power losses of the system. Sequential power flow is used to execute the combined AC-DC power flow by adjusting the estimation of DC slack bus injection to speed up convergence and to get more optimal results. Several systematic load increase scenarios are proposed in this study to provide stress loading on the system so that the performance of HVDC can be evaluated. This simulation was implemented on the IEEE 14-Bus System and IEEE 57-Bus System.

Interest in Generator Maintenance Scheduling (GMS) has increased due to the advent of demand-related expansion in size for modern power systems. Timely maintenance plays a significant role in minimizing failures and helps in averting cost incurred as a result of production shutdowns. The GMS problem is a complex and nonlinear optimization problem that specifies the schedule for carrying out planned preventive maintenance on power generation units. There is no clear concept to GMS model types and choosing the appropriate maintenance scheduling type. Thus, this paper presented a comprehensive review on GMS models in electrical power systems that covers the maintenance strategies, main elements of GMS models, and optimization methods used in solving GMS models. The list of references comprised related works from the years 2000 until 2020, which were classified into three based on the objectives. A new type of objective function for the GMS models was among the suggestions provided. A numerical example which focuses on a multi-objective GMS model and a proposed multi-objective Pareto ant colony system algorithm are also presented. The results of this review will not only enable researchers to gain a good overview of the existing GMS models for electrical power systems but also provide a source of references in choosing an appropriate maintenance scheduling strategy that is suitable with the type of generating unit and existing operating conditions.

The work presented in this paper aims to compare the effectiveness of different control strategies to improve the performance of the three-phase Induction Motor (IM). The Conventional Direct Torque Control (CDTC) was employed as the first strategy for driving the IM. This control strategy causes high ripples in the IM's torque and speed due to the hysteresis comparators and a variable switching frequency due to the look-up table. A modified DTC strategy based on Space Vector Modulation (DTC-SVM) was chosen as a second strategy to enhance the performance of the IM using the two-level inverter. This method, which leads to the reduction of the torque and speed ripples and achieves constant switching frequency. As the multi-level inverter becomes most popular than the two-level inverter, the third strategy is devoted to adopting the three-level flying capacitor inverter (TLFCMLI) -based DTC-SVM. The third strategy uses the method of mapping the multi-level space vector based on basic two-level SVM. Matlab/Simulink software package is utilized to implement the suggested controllers. Simulation results show that the DTC-SVM based on TLFCMLI significantly enhances the IM's performance compared with the other two strategies from the voltage and current profiles, torque, and speed points of view.

The performance of two Access Points (APs) Communication-Based Train-Control (CBTC) systems subjected to an imperfect channel state information (CSI) scenario is investigated. More precisely, we first model the realistic small-scale fading distribution for which the receiver only has the outdated CSI due to the mobility of the train. We then derive the Outage Probability (OP) of the train and the ergodic capacity of the system in the closed-form expression based on the considered channel model. Additionally, we formulate an optimization problem that minimizes the maximal OP, which corresponds to the location of the train. For such, the signal-to-noise-ratio (SNR) is minimized as a function of the position of two APs. The pattern search method is utilized to solve the considered minimization problem. Numerical results confirm that by the optimal placement of the position of APs, the OP can be significantly ameliorated compared to the other placement methods. Furthermore, the numerical results also illustrate that the proposed solution completely coincides with the exhaustive search but with much less computation time. Finally, the mathematical framework is verified extensively by Monte Carlo simulations.

Mobile Ad hoc networks deploy the network with the support of self-organizing and self-configuring mobile nodes. Due to the lack of centralization, the topological structure of the network fluctuates frequently. Preserving stable link communication to obtain reliable data transmission is the key challenge in the dynamic wireless network environment. This stimulates discrepancy on discovered route paths. To address this issue a novel approach called bootstrap aggregated mutual dependency ensemble clustering and learning agent based approach to eliminate stale routes in MANET (BAMDEC-LABA) is introduced. This algorithm is used to identify the stable link based on the metrics such as residual energy, receiving signal strength, less hop count and node behavior. Maximum dependency with less hop count route paths are classified by employing bootstrap aggregation method. Learning agent examines the node behavior and identifies the selfish and corruptive nodes using node cooperativeness and trust value. The occurrence of the link failure due to the malicious nodes intimated to all the nodes with the distribution of route error packet. The inconsistent route path is eliminated from the cache to preserve the link failure. The performance of the proposed approach is evaluated with different performance metrics such as routing overhead, packet delivery ratio, packet drop rate, and delay. When compared to state-of-the-art approaches, the proposed BAMDEC-LABA technique on an average minimizes the routing overhead by 26%, improves the packet delivery ratio by 18%, packet drop rate is considerably reduced by 68% and delay is found to be minimized by 27%. The proposed method outperforms when compared to state-of-the-art approaches.

Average Hausdorff distance that is an efficient measurement is widely used in face recognition method for measuring the dissimilarity between two sets of features. The New modified Hausdorff distance (MMHD) is a face recognition method, which uses average Hausdorff distance for measuring the dissimilarity between two sets of dominant points, which are features of face image. However, the disadvantage of the average Hausdorff distance is high computational complexity. Various methods have been proposed in recent decade with the purpose of reducing the complexity of Hausdorff distance computing. Local start search (LSS) is a state-of-art method for reducing the complexity of the Hausdorff distance computing. In this paper, we present how to use the LSS method for reducing the complexity of the computing the average Hausdorff distance. Firstly, a modification of the MMHD method, namely Least Trimmed New Modified Hausdorff distance (LT-MMHD) is proposed. The LT-MMHD method uses average Hausdorff distance of largest values for measuring the distance between two sets of dominant points. The proposed method gives higher recognition rate than the MMHD method for all conditions of face image. Finally, the LSS method is used for reducing the computational complexity of the proposed method. Experimental results show that by using the LSS method, the proposed method could reduce the computational complexity of 17%.
