In the paper we are showing a comparative study of some of the classification and the clustering algorithms so that we can find the alternatives for the datasets depending upon the requirement. These prediction systems can be used for the medical diagnosis as various algorithms in this paper have been categorized and simulation results shown. Prevalence informs the total case load at a given time...
Many of the survey report about vehicle accident say that, accidents are happening due to driver's drowsiness and over speed. Drunk and driving is another factor for accidents. If these mistakes are corrected accidents can be reduced, not hundred percent but up to the satisfied level. If accidents occurred, immediate first aid and treatment is necessary to save life. So once accident happened informing...
Nowadays web pages are mostly XML based and most of this information does not have well-defined Document Type Definition (DTD) or Schema. They are relatively huge document and incomplete in nature. Therefore effective answering of the XML document is tedious as it leads to irrelevant and more generic results thereby failed to offer the specific user's needs. To avoid this problem, an approach based...
Our aim is to model carbon nanotubes using Atomistix Tool Kit (ATK) software and simulate it. The CNT is designed toward fabrication of two-port and/or a three-port molecular electronic devices (FET). CNT design is functionalized with suitable molecules so that the functionalization of cnt as a logic citcuit is achieved by theroetical analysis for electronic transport, effect of gate potential, optimization...
Time is one of the important criteria which we have to consider in day-to-day life. Every one's passion is to retrieve the optimum data within a short span of time. In this paper we are observing the general time sensitive queries. Queries are also important along with finding topic similarity and final document ranking process. The proposal of this paper is to construct a general framework which...
A Duty Cycle Corrector (DCC) using a sigma-delta Analog to Digital Converter (ADC) is one of the high speed and low power method. The proposed DCC consists of a duty-cycle detector, a duty-cycle adjuster, sigma delta ADC and an output buffer. In order to achieve fast duty-correction with a small area, sigma-delta ADC controller used as a duty cycle correction controller. The proposed DCC circuit has...
In this paper we introduce a new approach to compute an energy renormalization factor and harmonic extension of a Level-3 Sierpinski Gasket (SG3). There are several methods to compute the harmonic extension for fractal objects. SG3 is one of the examples of fractal objects. But here we apply the electrical network interpretation which is done by applying the Delta-wye transforms procedure iteratively...
This paper presents a low complexity hardware design for computing Singular Value Decomposition (SVD) of the radio communication channel characteristic matrix. The hardware developed is suitable for computing the SVD of a sequence of 3 ×3 complex-value matrices used in MIMO-OFDM standards, such as the IEEE 802.11n. The information of the right singular-vector matrix can be fed back to the transmitter...
This paper presents a multimode optical fiber design that has high tolerance to bending. Average bending loss per mode for a standard 50 µm graded index multimode fiber is 8.06E+08 dB/km for a bending radius of 1.25mm and particularly for fundamental mode it is 2.18E+02 dB/km. Whereas, simulation results show that average bending loss per mode in the case of the proposed bend insensitive multimode...
This paper discusses the viability of Time Tick based Built In Self Test (TT BIST) implementation using the binary “hot” values of the Analog to Digital Converter (ADC) output for ADC testing. In traditional methods histogram testing is done using sinusoidal signals. But such testing methods are quite slow for high resolution ADCs. The proposed method uses dynamically generated ramp signal using current...
In this paper, a detailed description and comparision of speckle reduction of Synthetic Aperture Radar (SAR) image using transform is presented. The despeckling method is to reduce the speckle noise in SAR images, provided that the structural features and edges are not lost using Maximum a Posteriori (MAP) estimator based on wavelet and curvelet transform. These transforms are applied to noisy SAR...
Passwords are the most commonly used means of authentication as passwords are very convenient for users, easier to implement and user friendly. Password based systems suffer from two types of attacks: i) offline attacks ii) online attacks. Eavesdropping the communication channel and recording the conversations taking place on the communication channel is an example for offline attack. Brute force...
Telemedicine is an effective solution that provides medical aid from a distance. Provision of improved access to the health care facility economically to the rural population distributed across a wide area in our country is a challenging task. There is a need to go for a backbone telemedicine network that facilitates the availability of not just the basic health care, but also the futuristic applications...
Controller Area Network (CAN) is an attractive alternative in the automotive and automation industries due to its ease in use, low cost and provided reduction in wiring complexity. It was developed by Robert Bosch for communication between various digital devices inside an automobile where heavy electrical interferences and mechanical vibrations are present. This project is aimed at the implementation...
Heat exchanger is a device that exchange the heat between two fluids of different temperatures that are separated by a solid wall. The temperature gradient or the differences in temperature facilitate this transfer of heat. In General, temperature control system has the characteristics of non-linearity, large inertia and time variability. It is difficult to overcome the effects of these factors and...
Mobile Ad hoc Network (MANET) is a type of Ad hoc Network which changes its location and configures itself. MANETs have been broadly applied in various fields, such as military, health monitoring, and environment observation. It is a self-configuring infrastructure less network. A major advantage of MANET is its wireless nature as can be deployed more rapidly and less expensively than wired networks...
In this paper, presented a single double-sided circular disc bow-tie antenna for Ultra Wide Band (UWB) communication is being proposed. The antenna designs have been simulated using CST Microwave Studio. The antennacovers the UWB spectrum from 3.1 to 10.6 GHz, and had a return loss below than 10 dB throughout the entire band.A compact antenna area of 30.0 × 60.0 mm2 is obtained. The material used...
This paper presents an improved Z source inverter used to control the speed of an induction motor. The proposed Z source inverter (ZSI) can effectively reduce the voltage stress across the capacitors in the impedance network. This reduces the voltage range of the capacitors used, and also the cost of the proposed topology which is in turn used to control the speed of an induction motor which is used...
