Major technological, economical and environmental changes have generated interest of man in creating technologically smarter and safer world to live in. Human intelligence combined with artificial intelligence have been very useful in developing cognitive competence, namely the brain like thinking Smart Machines, with highly sensitive sensors (sensory organs) and digitized, telecommunication networks...
In this paper, a new method based on bivariate empirical mode decomposition (BEMD) for analysis of focal and non-focal EEG signals is proposed. Two dynamics are used to measure x and y pairs of EEG signals simultaneously. The bivariate EMD method decomposes the x and y pairs of EEG signal into a set of intrinsic mode functions (IMFs). The area is computed from IMFs plot of x and y pairs. This feature...
The hybrid capacitor has high energy density compared to standard supercapacitors along with long-term cycling ability. This makes them attractive for applications where repeated current pulses are required such as in electric vehicles. This study tries to optimize the mass of electrode material used in an aqueous hybrid capacitor. A new concept known as the variable supercapacitor have been introduced...
Edge detection has been used in many applications such as image analysis, pattern recognition and computer vision. Various edge detection techniques are used in images to filter out less relevant information while preserving the basic structural properties in different domains. In this paper a critical evaluation of various edges detection techniques with soft computing techniques has been examined.
The emergence of supercapacitors as an environment friendly energy storage device has generated a lot of interest in industry and academia. Carbon electrodes used in this device can be derived from biomass. This study tries to use dried banyan tree leaves and rose petals as a precursor to produce activated carbon. The activated carbon is then used to develop supercapacitors in the symmetrical and...
Increasing demands of LCD panel with high color depth and resolution makes it hard to design a buffer with such resolution. Since buffer design determines the speed, resolution, voltage swing and power dissipation of LCD drivers. But the resolution of the buffer amplifier depends upon settling time, low offset voltage and slew rate. Generally the methods used to reduce offset voltage are output offset...

The average Power output performance for the blade NACA4412 comes out to be 6W...
In this paper the design of multipliers which is less complex and power consuming is made of basic electronic components such as gates and adders. This design lowers the complexity of the circuit and works on the basic principle of multiplication and less number of transistors. The results show the multiplier is less complex and works effectively in large multiplications.
Managing congestion in transmission lines with continuous power flow in deregulated power system is a complex task. For maintaining overall security and reliability of the system it is to be ensured that transmission lines are loaded below their thermal limits. Congestion management includes technical as well as economic issues. Rapid transactions of power through transmission lines lead to change...
This paper presents a comparative study on p- and n-channel MOSFET embedded current mirror integrated pressure sensing structures. The pressure sensing structure consists of three MOSFETs connected in a resistive loaded current mirror configuration. The input constant current source MOSFET of the current mirror acts as a reference transistor and the output MOSFETs are the strain sensing elements....
Contrast enhancement is one of the most important issue of image processing. Contrast enhancement can be done in spatial domain or in frequency domain; in spatial domain, the pixel intensity data of the image is mapped to new intensity level via an intensity level transformation function. The intensity level transformation function can be defined using some mathematical equation derived from the image...
Development of integrated electronic and photonic circuits has led to distinctive data processing and transport capabilities. Scaling these devices to smaller and smaller dimension make these devices not only faster, power efficient and inexpensive components, but also lead to new challenges. A very important challenge is the growing size mismatch between photonic and electronic elements. To overcome...

In this paper, Method of Moments technique is used to analyze the Circular loop array antenna in the VHF (Very High Frequency) band with a loop thickness of 0.04m and radius, 0.1?. RWG (Rao-Wilton-Glisson) edge elements are used as basis function and Galerkin's method is used to cast the problem as a matrix equation. The corresponding radiation pattern in the far zones for both types of antennas are...
Electric distribution planning and research have been focused on the reliability and flexibility of electric supply at the consumer end. Due to increase in weather related outages, natural disaster like hurricanes, earthquake etc. in recent years, ample research has been sprouted to enhance the resilience of the power grid. This paper presents the concept of resilience in Infrastructure systems, measuring...
The complexity of many image processing applications and their stringent performance requirements have come to a point where they can no longer meet the real time deadlines, if implemented on conventional architectures based on a single general-purpose processor. Acceleration of these algorithms can be done by parallel computing. Parallelism can be accomplished both at hardware and software levels...
Power generation from solar photovoltaics has been increasing since the last decades. Currently, ground-mounted solar-PV, solar rooftop-PV, Building integrated-PV, and Roof-Jack mounting system are the available methods in photovoltaics for deployment of solar energy. The performance of a solar PV system has depended mainly on conversion efficiency which depends on the material used for construction,...
