Big data refers to several collections of data sets so large and difficult that it becomes complex to process using traditional information giving out applications. The issues include study, confine, curation, investigate, division, storage space, convey, image, and confidentiality violation. The characteristics of big information are volume, velocity, value and variety. Big data is the information...
A Wireless Sensor Network (WSN) is a network comprised of hundreds to thousands of tiny self-organizing sensor nodes. Security in WSNs has become a major issue especially in critical sectors such like battle field monitoring in the military. Research work has been conducted in key management, which is one of the most important security primitives. Though the use of public key cryptography schemes...
This paper contains self error detecting and correcting technique for high speed and performance applications. DAC (digital to analog converter) is the basic building block for communication purpose. Self detecting and correcting technique is connected at the output of Digital to analog converter. For achieving high speed resolution hybrid architecture of DAC is used. In which LSB are implemented...
The efficiency and output light power is the most important factor for a Light Emitting Diode (LED) application. In pursuit of high Internal Quantum Efficiency (IQE), the Violet GaN/GaAlInN Multiple Quantum Well (MQW) LEDs are simulated by APSYS software. The effects of variation in number of wells and thickness of well on LED characteristics is observed & these two parameters are optimized for...
Particle Swarm Optimization with Aging Leader and Challengers (ALC-PSO) method, which represents a novel approach for optimization problems, is applied for radiation pattern synthesis of a three ring Concentric Elliptical Array Antenna (CEA) of isotropic elements which can generate beam pattern with maximum reduced Side Lobe Level (SLL). This paper introduces a recently developed metaheuristic algorithm,...
In Analog application, multipliers plays a vital role. They are used in many fields like artificial neural networks, image processing, modulators etc. In this paper, a low power and low voltage CMOS analog multiplier is presented with performance analysis and design implementation by using Exponential Approximation circuit. In this design, MOSFETS are operating in weak inversion region in order to...
An analog to digital converter is a mixed signal device which converts an analog electrical signal into digital data. Thus they form the front end of any digital circuit in real life signal processing. Looking at the industry progress in recent years, the need to design an compact low power, high speed and wide bandwidth ADC has increased. There have been different architectures of ADCs which are...
One of the challenges faced in video retrieval is accurately detecting and extracting the objects in motion. The properties of the moving objects from the query clip are obtained, represented quantitatively, and compared to the corresponding features of the moving objects in the videos stored in the database. If a large number of features match, it generally indicates that the objects are similar...
