Background: Microstrip antenna has gained significant attention for a large number of communication systems due to its adaptable features and compatibility. Objective: The major objective of this manuscript is to assess the microstrip antenna technology for structure adaptability, the feature based performance capabilities, design and versatility. Methods: The major reviews conducted in every decade on antenna technology h Read More

Background: The Open Cloud Computing Alliance (OCCA) strives for more Cloud Computing Service Providers (CCSP) to join the alliance. OCCA only requires CCSP to provide virtual computing resources and does not care about the methods of the underlying implementation, which leads the open-source cloud computing to a larger scale and more efficient. Due to the differences in service modes and service categories, the cl Read More

The Vector control scheme widely used for control purposes of PMSM drives requires rotor position information. Generally, sensors are used for this purpose, which increases the cost, size, and complexity of the system and also reduces the efficiency of drives. Therefore, it has become essential to avoid the use of these sensors and go for sensorless drives. In this paper, different types of speed and position estimation techniques Read More

Background: Winding deformation is one of the most common faults in power transformers, which seriously threatens the safe operation of transformers. In order to discover the hidden trouble of transformer in time, it is of great significance to actively carry out the research of transformer winding deformation detection technology. Methods: In this paper, several methods of winding deformation detection with o Read More

Introduction: Incomplete data sets containing some missing attributes is a prevailing problem in many research areas. The reasons for the lack of missing attributes may be several; human error in tabulating/recording the data, machine failure, errors in data acquisition or refusal of a patient/customer to answer few questions in a questionnaire or survey. Further, clustering of such data sets becomes a challenge. Objec Read More

Background: Ventricular Arrhythmias, one of the fatal heart diseases, requires timely recognition. The nonlinear and random nature of heart rate makes the diagnosis challenging. Introduction: The research work in this paper is divided into three phases. In the first phase, classification of some of the ventricular arrhythmias is done in four classes as Premature Ventricular Contraction (PVC), Left Bundle Branch Block (LBBB) and Read More

Background: The Remote Terminal Units (RTUs) in the Distribution Automation System (DAS) are widely used in the field in recent years. It is lack of sample data in different operation status that makes the RTU maintenance improper. The weight allocation for the monitoring indicators in the health status evaluation needs to be identified efficiently and properly. Methods: A systematic health status assessment indicator system Read More

Background: This paper presents the comparative study of power dissipation, delay and power delay product (PDP) of different full adders and multiplier designs. Methods: Full adder is the fundamental operation for any processors, DSP architectures and VLSI systems. Here ten different full adder structures were analyzed for their best performance using a Mentor Graphics tool with 180nm technology. Results: From the analy Read More

Background: Due to the openness of wireless fading channel, it is easy to be disturbed by other transmission signals and noises. Encryption and decryption can guarantee the security of signals, and Physical Layer Security (PLS) which uses the features of fading channels itself to ensure the security of signal transmission has also been widely concerned. In addition, considering the wide applications of Κ-μ shadowed distributio Read More

Background: This paper presents an optimal power delivery system for a hybrid microgrid consisting of a solar PV, wind farm, battery storage and diesel generator. The fuzzy logicbased control approach is used to match the generation and consumers’ demand. Methods: The load demand is assumed to vary hourly in a day and season to season in a year. The frequency of AC (alternating current) bus may deviate from standa Read More

Background: The MEMS scanning mirror prototype is a spatial scanning device, which has advantages such as light mass, low drive voltage, large scanning and high angular measurement accuracy. Methods: The MEMS scanning mirror prototype uses the piezoelectric driving principle to drive the micro-structure to realize two-axis scanning. The corner of the MEMS scanning mirror is measured by using a piezoelectric resistanc Read More

Background: This article studies the issue of adaptive neural dynamic surface control for the chaotic permanent magnet synchronous motor system with constrained output, external disturbances and parameter perturbations. Methods: Firstly, a virtual controller and two practical controllers are created based on the backstepping framework. In the process of creating controllers, adaptive technique and radial basi Read More

Background: Remote area electrification is a social responsibility that needs to be catered by research fraternity. One of the most viable technology as a solution is the Renewable Energy Source (RES) based power generation. However, RES is intermittent and thus, mostly ineffective without an energy storage device. Energy storage device comes at increased cost and may not be a cost-effective solution to the problem.

Methods: In this paper, by combining a fixed-point 256-point FFT a Read More

Background: High-Efficiency Video Coding (HEVC) is a recent video compression standard. It provides better compression performance compared to its predecessor, H.264/AVC. However, the computational complexity of the HEVC encoder is much higher than that of H.264/AVC encoder. This makes HEVC less attractive to be used in real-time applications and in devices with limited resources (e.g., low memory, low processing Read More

Background: With the development and innovation of digital information technologies and new-generation Internet information platforms, new types of information exchange methods have been spawned. It has broken the restriction of the traditional internet boundary, and integrated all round connections between people and objects.
