Introduction to Memristor and Memristive devices in VLSI design and electronics add new features to both analog and digital circuit design. Memristor finds applications in different fields like memories with a non-volatile behaviour (NVRAM-Non-Volatile Random Access Memory), neural networks, robotics to mimic biological entities, Low-power and remote sensing applications, Analog computation and circuit...
In this paper, the detection of faulty elements in a linear antenna array with different combination of faulty element; is presented. The task of finding faulty element position and its level of fault in antenna arrays has been solved by using Iterative Fast Fourier Transform (IFFT) technique. A Chebyshev antenna array of 30 elements with specific sidelobe level (SLL) is considered as the basic antenna...
In networking data rate varies from application to application and usually ratio of peak data rate is much higher than average data rate i.e. bursty data transfer. Hence, service provider/Network cannot use normal multiplexing as it requires huge bandwidth with very small utilization factor, so there is a requirement of statistical multiplexer, which is based on incoming data rate statistics and efficiently...
Omni drive robots operate by combined motion of more than 2 wheels leading to a force vector in resultant direction and thus enabling the robot to travel in that direction. Omni drive systems are quite efficient from the travelling point of view as compared to non-holonomic (non omni drive) systems, which require stopping at a position and taking a turn. This paper describes a very sophisticated yet...
Micro-grid (MG) is formed by renewable sources. MG is a small scale network of low voltage distributed renewable energy resources (DER). This paper reviews the optimal energy management for a MG under various constraints. This paper emphasize on the different methods adopted by various authors to optimize fuel cost, manage peak load and reduce gas emissions by scheduling generation of DERs in each...
To achieve good performance from the system, performance index plays vital role in the objective function. In this paper various performance indices are used as the objective functions. The choice of the objective function is the most crucial and complicated step in applying any optimizing algorithm for an adaptive control system. They are used to evaluate fitness of items for iterations. The various...
In regulated electricity markets, there is trading of large volume of power over existing transmissions lines. Due to this, some corridors experience congestion and may endanger system security, stability and reliability. To overcome this, Unified Power Flow Controller (UPFC) can act as a decongestion device and can improve power flow. The proposed method uses a modified gravitational search algorithm...
This paper investigates acoustic patterns generated by different liquids in real time based on spectral analysis technique which finds a lot of relevance in various fields related to defense and homeland security. Some of the drawbacks with existing techniques include limitations with acquisition of well defined patterns for various liquids. To overcome these limitations, this paper describes a technique...
As an element of research initiative to aid the prospective smart grid issues and to integrate green energy facilities lucratively a demonstration project “Design & Development of Smart Micro-Grid” is being executed in Energy Center, Maulana Azad National Institute of Technology (MANIT), Bhopal. In view of the fact that most renewable sources are intermittent in nature, their integration into...
The analysis and the formation of the electric energy industry implements by forming a platform for the three components covering the generation, transmission, and distribution. Once the electric power is formed, it is further passed through the transmission lines having high voltage and large capacity to the regions in which the electricity will be consumed. Then it is converted to a voltage that...

There are thousands of applications present in play store today which fulfils our everyday life's needs. These Online Application Stores gives user hundreds of thousands of application in one minute. All users are aware of the fact that any individual run its application in play...
In the recent few years, many wireless sensor networks have been distributed systematically in the real world to collect valuable raw sensed data. However, the crucial point of challenge is to extract high level knowledge from this raw sensed data. In the application of data analysis, a necessary preprocessing step is anomaly detection, also known as deviation detection or data cleansing. Outliers...
With the emerging computation techniques in the field of medical science such as in Ophthalmology; it is often required an automated technique for identification of pathological condition such as diabetic retinopathy which might cause serious problems like blindness. Retinal diseases are often characterized by modification in retinal vessels. Retinal blood vessels observed with fundus imaging provides...
Memory is an important part of every computing system. In SOC, 90 to 92% of the total chip area is covered by embedded memories (ITRS 2009) and that means memory density is higher than the logic density. Therefore testing and diagnosis of memories are important issues in the SOCs. Yield of memory is affected by the faults present in memory which also affects the yield of SOC. Built in self-repair...
This paper presents a novel control system for wind energy conversion system integrated with Solid oxide fuel cell (SOFC). In recent years the Double-Fed Induction Generator (DFIG) gaining more popular due to their variable speed and variable pitch control. A dynamic model of SOFC fuel cell integrated with a doubly fed induction generator to maintain grid voltage constant 440 V and 50 Hz. The conventional...
The aim of this paper is to maximize the overall exergy efficiency of single channel photovoltaic thermal module. The solar panel (PV module) generally gives electrical efficiency in the range of 7% to 12%, the rest energy being dissipated in the form of heat losses. To recover thermal energy from the module photovoltaic thermal system has been simulated. The analysis in this work investigates the...
A compact planar monopole ultra wide band (UWB) antenna is described with coplanar waveguide (CPW) feed for MIMO applications. The radiator and ground plane of the antenna are etched onto a piece of substrate with an overall size of 28.5mm × 42mm × 1.524mm. Implication from simulation shows that the antenna achieves a broad operating bandwidth of 3.2–10.6 GHz for a −10 dB return loss and Comb shaped...
Arrhythmia can be detected by carefully studying the electrocardiogram (ECG) and the distortions in the QRS complex. Since the appearance of the distorted beats, the indicators of arrhythmia, may occur randomly with respect to time and span over a large time interval, an automated classification mechanism may reduce the tedium in identifying and isolating these beats. This paper proposes an arrhythmia...
