TL;DR: This paper compares the performance parameters of rectangular and circular micro-strip antenna for 2.4 GHz RFID wireless applications using IE3D simulation software and results are compared with practically measured results.
Abstract: This paper compares the performance parameters of rectangular and circular micro-strip antenna for 2.4 GHz RFID wireless applications using IE3D simulation software. The main parameters of comparison are return loss, gain, and area. The main objective of the work is to obtain the reduction in the size of circular antenna compared to rectangular for same frequency of operation. Impedance matching between the feeder line and radiating patch is done using planar micro-strip transmission lines. Quarter wave feeding technique is used for both the antennas to provide best matching between antenna and the source. Simulation is done using IE3D simulation software and parameters like bandwidth, return loss, and gain are measured. Results are optimized using optimizing techniques and results are compared with practically measured results. Finally antennas are fabricated and tested using in-house facilities.

TL;DR: In this paper, the authors used a psychological questionnaire to assess the stress level of engineering students and found that female students are less stressed when compared to the male students in terms of stress.
Abstract: In this competitive era, students are undergoing a lot of stress due to societal influence, financial status, and academic environment. This is leading to many psychological disorders such as depression, anxiety, and many others. One student commit suicide every hour in India, and in most of the cases, stress and pressure are the main reasons for the deadly attempt. The high level of stress is hindering the performance of the students in the academics. It is necessary to find out the stress level of the students and guide them through different techniques that help them in reducing stress levels. There are many ways to investigate the level of stress among the students. Techniques like psychological questionnaires, physiological measures like blood pressure, salivary alpha amylase, and vagal tone can be considered for analyzing stress in students. Perceived stress scale (PSS) is one of the standard psychological questionnaire methods used to analyze stress level of an individual. It is a measure of degree to which situations in one’s life are appraised as stress. The scale includes a series of general queries about present level of stress experience. The scale is free of content specific to any subpopulation group. The PSS is used to categorize the subjects as less stressed, moderately stressed, and highly stressed. The data through responses from 486 engineering students was collected to investigate the stress level of the students. The data thus obtained is validated using the statistical tool ANOVA. ANOVA test is a way to find out if experimental results are significant. The gathered data is validated for statistically significant group and used for further analysis. The results from the analysis of PSS showed that the female students are less stressed when compared to the male students. The result can further be imbibed in an intelligent system which could detect the level of stress and suggest a method or technique to the subject so as to reduce the level of stress.

TL;DR: Intentional islanding is tested by developing the model using MATLAB/Simulink environment and results are obtained, which validate the effective operation of the proposed controller and power electronic devices.
Abstract: Grid connected Distributed generation (DG) provides reliable and secured power. The research focus is to achieve adequacy and security in the grid connected photovoltaic (PV) power generation system. The islanding is the situation where DG continues to operate with the utility disconnected. Islanding detection should be done with minimum possible time when it occurs to ensure continued stable operation along with safety of linemen and the customers' equipment. Of the renewable energy sources, PV system is most suitable source for clean generation and suitable for any areas of applications. This paper deals with the PV cell model as DG integrated with the utility and operates in grid connected and intentional islanding mode. Islanding detection is carried out with passive islanding detection technique. The DG is integrated to utility to operate at grid voltage and frequency. Intentional islanding is tested by developing the model using MATLAB/Simulink environment and results are obtained. The simulation results validate the effective operation of the proposed controller and power electronic devices.

TL;DR: The optimal placement and sizing of the devices are done by formulating the objective function with minimization of cost of the generation and minimizing the cost of Facts devices by Cuckoo search algorithm.
Abstract: The power system deregulation requires thechange in reactive power compensation in the power system. The optimal placement of FACTs (Flexi ble AC transmission system) devices is mandatory to recalculate the reactive power compensation in deregulation case. The FACTs devices generally used in series and shunt conections. Here the various facts devices connected in series & shunt combination simultaneously. The optimal placement and sizing of the devices are done in this paper by formulating the objective function with minimization of cost of the generation and minimizing the cost of Facts devices. MALAB is used for writing the code. IEEE 14 bus system is used to here for testing the system. Placing the FACTs separately and simultaneously are studied in case study. Cuckoo search algorithm is used to identify the solution to the optimization problem.

TL;DR: This work, presents the effect of energy on delay and throughput with respect to different types of deployments like static and dynamic deployments in Wireless Sensor Networks.
Abstract: Wireless Sensor Networks are gaining more and more importance in present era. Recent Advances in WSN have extended the applicability of these to wide range of real time applications. In these applications, energy is one of the scarce resources. Hence, the main goal of any application using WSN is to spend less energy and extend the lifetime of the WSN. For any type of network communication, quality of service plays an important role. QoS can be either Application-Specific or Network-Specific. Network-specific QoS is measured with respect to different parameters like delay, bandwidth, and throughput. Deployment of nodes in WSN's are classified as static and dynamic deployments. The effect of energy on quality of service and deployment can be of importance with respect to extending the network lifetime. This work, presents the effect of energy on delay and throughput with respect to different types of deployments like static and dynamic.
