Tuning and performance analysis of thyristor controlled series capacitor (TCSC) and power system stabilizer (PSS) is most important issue to mitigate the phenomena of low frequency oscillations. To damp out all poor modes, coordination between TCSC and PSS controllers under different loading conditions is formulated as optimization problem. Enhancement of damping of electromechanical modes (EM) through maximizing of damping ratio is the objective function which fixed by Particle Swarm optimization (PSO) algorithm. Developed approach is then, implemented on SMIB. To validate effectiveness of proposed algorithm, eigenvalue analysis as well as nonlinear time domain simulation is demonstrated considering different operating modes.

T60 relay is one of the new digital relays has been designed to meet the requirements of high sensitivity, reliability and high speed. This development led to notable simplification in transformer differential protection 87T function by reducing cost, cabling and auxiliary equipment. However, still miss-operation cases in transformer differential protection can occur from time to time. This paper reports on two unwanted-operation cases of transformer differential protection happened in Garie power plant in Sudan. In the both cases, failures in the CT/VT module of T60 relays cause unwanted operation of the protection system. These failures could be a result of aging, problems in DC power supply or from the design of these modules. More investigations are needed to find the roots of these failures. In the both cases, the failures are hidden type in which the relay will not operate unless unusual event has happened. The failures could have been detected and removed, if the preventive maintenance was effective. In order to insure reliability and sensitivity of the relays, preventive maintenance should take place from time to time.

The demand of innovated advanced control for incubator is rabidly increasing due to the significance of reducing the death ratio among the infant baby. In incubator, there are numbers of parameters need to be monitored. This paper presented an advance control system used to monitor some important parameter that affect the life of infant baby. This technique simultaneously monitored and controlled more than one parameter with advanced control and provides smooth operation helps to increase the accuracy of the system. The proposed system contained four temperature sensors which are used to adjust the incubator temperature and extended to monitor the skin temperature. The system also used two sensors to measure humidity. An application page was designed to ensure easy monitoring service for user. The systems based on Arduino and offer the ability to control incubator using the serial port.

Vehicular Ad-hoc Network (VANET) turning into a hot research topic because of its pertinence in the areas of road safety, entertainment and driving experience. In wireless networks the information losses are obsessed with the nodes speed, the routing protocol used and therefore the accessible channel. The main objective of this paper is to compare the performance of three routing protocols particularly Ad-hoc On Demand Distance Vector (AODV), Optimized Link State Routing (OLSR) and Geographical Routing Protocol (GRP) from a single node point of view under highway mobility pattern with voice traffic in terms of routing traffic sent and received, end to end delay and throughput. According to simulation results it’s clearly discovered that GRP protocol performed better than other protocols in terms of routing traffic sent and received and throughput whereas OLSR is the most effective for time sensitive applications.

A robotic arm having two links is considered in this report for modeling and control. First the dynamic model of the robot is obtained using the so-called Lagrange equation, then a robust control strategy based on the conventional sliding mode control is introduced to control the motion of the robot at specific position for pick and place tasks along with PID control scheme. The results of the two controllers are compared. From the simulation results the SMC is found to be superior to the PID controller in term of fast and robust response yet with higher control input. High join speeds are observed in case of SMC which are related to the high control signals.

Design and simulation of a voltage source grid connected inverter (VSI) have been introduced in this paper. A grid connected PV array of 250 KW connected to a 25-kV grid via a three-phase voltage source inverter (VSI) was designed and simulated. Mathematical and electrical equations of the design have been presented. Different components of the system have been described and simulated using MATLAB/ SIMULINK. A control unit of the grid-side inverter controlling the maximum power point tracking (MPPT), DC voltage regulator, current regulator, pulse width modulation (PWM) and phase lock loop (PLL) circuit have been discussed.

Electricity produced from renewable energy sources (RES) such as wind power (WP) offers a huge possibility for meeting the future power demands (PD). However, the utility of these sources needs an efficient energy storage system (ESS) to maintain the power grid system stability through the whole operation periods. Battery energy storage (BES) systems are capable to co-locate with RES to make balancing which can store the excess energy from these sources and reused it when needed. In this paper, integration of hybrid wind/battery system into diesel power plant (DPP) is presented. The proposed system is modeled as security constrained unit commitment (SCUC) problem with mixed-integer linear programming. The simulations have been performed using Gurobi8.0.0 solver implemented in MATLAB and the results show that the significant fuel saving can be achieved through the integration of the wind and the BES. The proposed system is suitable for remote areas applications to minimize the use of fossil fuels (FF), reduce the greenhouse emissions such as $CO_{2}$, increase the power generation and helpful in the power system management.

Conventional techniques for monitoring glucose levels are limited by tremendous side effects. Therefore, the noninvasive continuous glucose monitoring system was introduced to provide continuity of check, less side effects with an accuracy of 89%, by calculating the glucose level from the output voltage of the probe pulse oximeter through an equation derived using Microsoft Excel Regression Analysis Tool, allowing its display in a liquid crystal display and further regulation by injecting insulin or glucagon.

Sickle cell disease (SCD) is the most popular inherited blood disease, that red blood cells change its shape form circular shape to sickle shape and loses its main job which carries oxygen throughout the body. The watershed segmentation method has become highly developed for automated analysis of overlapping red blood cell microscopic images. The aim of this work is to suppress over segmentation problem which is a major drawback of the watershed algorithm. The experimental results showed that, watershed is most effective when done on filtered image using non local means denoising method. The effectiveness of the proposed method is validated by analyzing the image segmentation quality measures. The proposed method provides higher performance in term of accuracy, sensitivity and specificity factors.
