Cloud computing and virtualization are two key technology priorities for telecom service providers. Besides total cost reduction, there are many strategic objectives while adopting cloud technology into the telecom sector. Telecom service providers core assets and strength lies in their communication networks, but these alone are not enough to maintain the industry in the higher level that it once...
This paper describes a novel non-invasive approach to monitor blood glucose using basic salivary electrochemical parameters. Diabetes is a known systemic disorder which affects the metabolism of the body. Saliva is an oral multiconstituent fluid which reflects changes in the body physiology of diabetic individuals as compared to healthy ones. The various salivary parameters which are taken into consideration...
In this paper, we propose a novel approach for detecting the text present in videos and scene images based on the Multiscale Weber's Local Descriptor (MWLD). Given an input video, the shots are identified and the key frames are extracted based on their spatio-temporal relationship. From each key frame, we detect the local region information using WLD with different radius and neighborhood relationship...
This article gives an ample idea about Sliding Mode Controller (SMC) implementation to a DC-DC boost converter for a Solar system to track Maximum Power Point (MPP). SMC implementation accompany three criteria's; they are Hitting, Sliding Mode (SM) Existence and Stability. One diode Photovoltaic (PV) model is designed for lighting applications, and PV output is connected to a boost converter to regulate...
An increasing number of safety features are being added to various engineering designs and processes of today and they have become the most important consideration in every design. Construction is a high-risk industry, hence the need for such systems is more pronounced. The cost of repairing damaged parts is significant due to the expensive price of construction machinery and related equipment. Based...
This paper presents rapid prototyping of FPGA based digital controller for Distribution STATic COMpensator (DSTATCOM) using Matlab/Simulink and System Generator. The MATLAB/Simulink models are optimized and converted to target-specific synthesized VHDL code for FPGA implementation. Simulation, co-simulation, system level design and verification for rapid prototyping of FPGA-based digital controller...
This paper deals with design and performance analysis of automatic generation control (AGC) of a two area six unit interconnected power system. A single input Fuzzy Proportional Integral Derivative (FPID) controller is used to study the transient response of the proposed system. Area-1 consists of two thermal generating units with reheat turbines along with a diesel unit and area-2 has two thermal...
Wireless body area network collects information from medical devices that monitor the physiological parameters of a human body. Energy constraints of medical devices and bounded latencies of medical applications are the chief QoS requirements of WBANs. With the standardization of the WBAN network, viz. 802.15.6 standard, mechanisms for medium access have been specified which can be skillfully manipulated...
Synthetic Aperture Radar (SAR) images are inherently degraded due to the coherent nature of the scattering phenomena called speckle. The presence of speckle decreases the utility of the SAR images by reducing the ability to detect ground objects. It affects the quality of the image adversely and hampers the observation of vital and crucial information present in the image. In this paper, we present...
This paper evaluates the performance of conventional and advanced discontinuous space vector pulse width modulation(PWM)with the variation in placement of clamping position (zero vector changing angle). This paper investigates the effect of various clamping sequences on THD and on switching loss. The variation in clamping sequences over the different region of a sector and its placements are carried...
Accurate forecasting of chaotic and nonlinear time series has been a key area of research in last two decades. They find extensive applications in stock market prediction, forecasting weather conditions, determining the inferences of chemical reactions and many more. The manuscript deals with development of a new hybrid model based on Wavelet Neural Network (WNN) trained by Cat Swarm Optimization...
The proposed interface is a capacitance to frequency convertor (CFC), which is simple and effective solution for reading capacitive difference between the sensor capacitance and reference. The output is a square wave signal, where the signal frequency is proportional to the sensor differential capacitance. Proposed interface integrates the advantage of two basic measurement techniques, bridge and...
Over the past few years, with the exponential expansion of the World Wide Web and its applications, there has been a paradigm shift in the way people learn — Massively Open Online Courses (MOOCs) and other online learning recourses are fast replacing conventional textbook learning. Efforts are also being made to develop and foster crowd sourced massive open repositories of learning objects, which...
College of Engineering, Pune(COEP) Microgrid, a project by the students of College of Engineering Pune aims at establishing a microgrid in the college campus serving as a living laboratory for research and development of novel grid technologies. Proposed microgrid has an AC-bus and DC-bus, interconnected together with a tie line DC-AC converter. Synchronization with AC bus requires inverter output...
The development of the Internet in the recent years has made it possible to access different information systems anywhere in the world. Information Integration is the merging of information from heterogeneous sources with differing conceptual, contextual and typographical representations. In this paper, we exploit Information Integration techniques for movies data from different sources over the web...
In this paper a new boost fifth-order point of load dc-dc converter is proposed. A digital controller is then designed to ensure load voltage regulation against expected disturbances. The proposed converter is capable of giving a higher voltage gain in comparison to other fourth and fifth-order boost topologies reported in literature. Through steady-state analysis various design expressions for the...
Local field potential (LFP) has been of growing interest in interpreting specific motor activities and higherlevel cognitive functions for neurophysiological investigation. LFP denote the neural activity recorded from the ensemble of neurons which carry information in the frequency range of 1–200 Hz. The requirements on the electronics of an amplifier sensor used to measure LFP signals is very stringent,...
This paper proposes a Motor Current Signature Analysis technique to diagnose the stator inter turn fault in induction motor using wavelet transform and Support Vector Machine as tools.

Lifting algorithm based wavelet decomposition is implemented in ARM processor based system using which the approximation...
Direct Torque Control (DTC) of brush less DC (BLDC) motor having trapezoidal back emf with a reduced torque ripple is presented in this paper. Unlike conventional six step PWM technique, a quasi square wave current is obtained by selecting the voltage vectors from the pre defined switching table, which results in faster torque response compared to the conventional scheme. In the constant torque region...
Tracking manoeuvring aircrafts is an extremely challenging and important task as far as civil air traffic control is concerned. Considering a multiple switching model design for describing the aircraft dynamics can provide more accurate estimation results than that obtained from a single model design. In this paper, the cubature quadrature Kalman filter (CQKF) has been used to estimate the position...
