Prof. Swati Agrawal
DOI: 10.17148/IJIREEICE.2015.3201
Abstract: The use of the VHSIC Hardware Description Language (VHDL) has become very important to the simulation and implementation of digital systems in both industry and educational settings. Al-though VHDL is a powerful language with many capabilities, it has downfalls when considering the difficulty in learning the language as well as its limited capabilities for transitioning a design from initial concept to design entry and verification stages. This paper discusses techniques used to teach the VHDL design methodology to graduate students, as well as methods used to go through a complete design cycle from initial concept to final implementation. VHDL design techniques were developed using various projects and homework assignments, and different approaches to implementing the same function allowed direct comparisons of the speed and size of the designs. Different processes for taking a design from ini-tial concept through chip implementation were discussed, and one example of the process is discussed here. This paper describes the implementation of full adder using VHDL technology which meets less complexity requirement ,it also shows how efficiently digital system ie Full Adder is implemented upto layout level results shows technological map RTL view ,chip floor plan ,chip layout ,output waveforms showing voltage Vs time relations and verification of truth table .

Y.N.Vijayakumar, Dr. Sivanagaraju
DOI: 10.17148/IJIREEICE.2015.3202
Abstract: The latest development of Convertible Static Compensators (CSC) drives the importance of the Flexible AC Transmission System (FACTS) controllers to higher levels because of their controllable nature and effective power flow management of multi-line systems. There are several possibilities of operating configurations of FACTS devices by combing two or more converter blocks with flexibility. To realize the effect of CSC on a given power system, Interline Power Flow Controller (IPFC) is considered and Power Injection Model (PIM), Voltage Source Converter Model (VSM) and Hybrid Model for the same device is proposed in this thesis. The comfort in mathematical modeling and the incorporation procedure in Newton- Raphson load flow with these models increase its importance. Most of the literature concentrates on the voltage based controlled power flow using equivalent power injections. But the main contribution in this thesis is, to propose PIM, VSM and Hybrid models of IPFC to incorporate in NR load flow. By varying the device control parameters the variations in the system parameters is observed and are analyzed with the supporting results. Numerical results for HALE network and IEEE-30 bus systems without and with IPFC for the variation of device control parameters for each of the model are presented in detail. The obtained results show the performance of the proposed IPFC models.

Naveen Ku. Dewangan, M. K. Kowar
DOI: 10.17148/IJIREEICE.2015.3203
Abstract: Electrocardiogram (ECG), a non-stationary signal, is extensively used as one of the important diagnostic tools for the detection of the health of a heart. Comparison of overall ECG waveform pattern and shape enables doctors to diagnose possible diseases. Currently there is computer based analysis which employs certain signal processing to diagnose a patient based on ECG recording. The Electrocardiogram may contain various artefacts, noise and baseline wander when ECG is recorded which severely limits the utility of the recorded ECG and thus needs to be removed for better clinical evaluation. Signal pre-processing helps us remove contaminants from the ECG signals. The baseline wander and other wideband noise are not suppressed by hardware equipments. Software schemes are more powerful and feasible for offline ECG signal processing. Automatic detection of R peaks in a QRS complex is a fundamental requirement for automatic disease identification. Recently, numerous research and techniques have been developed for processing, detection of QRS complex, P and T waves of ECG signal. All these techniques and algorithms have their advantages and limitations. This proposed paper discusses various techniques and transformations proposed earlier in literature for processing, QRS complex and P and T wave detection of ECG signals and make comparison among them.

DOI: 10.17148/IJIREEICE.2015.3208
Abstract: A simple and low cost machine vision system for fault detection and identification is envisaged. The proposed system works on a Beagle Board single board computer. The system can be used to detect cracks or texture differences in classifying objects, especially in food processing industries. It essentially uses a camera for the image capture and process the image in the Beagleboneblack. Currently an online machine vision system on a conveyor line is made up of several cameras that are networked to a single computer. The camera provides the images at high rates and the software on the computer does the processing and makes the decisions to reject the product or not. The goal of this project is to design a smart board level machine vision system using a beagleboneblack with its own image sensors/cameras. The system will have its own algorithms for common machine vision tasks and will be networked to a main system to get output results.

DOI: 10.17148/IJIREEICE.2015.3209
Abstract: A low-power flip-flop (FF) design featuring an explicit type pulse-triggered structure and a modified true single phase clock latch based on a signal feed-through scheme is presented. The proposed design successfully solves the long discharging path problem in conventional explicit type pulse-triggered FF (P-FF) designs and achieves better speed and power performance. Based on post-layout simulation results using cadence virtuoso CMOS 180-nm technology, the proposed design outperforms the conventional P-FF design. The proposed design features the best power-delay-product performance in both implicit and explicit type flip flops under comparison. Counters can be designed using such flip flop. As a result power consumption is reduced compared to conventional methods. In this paper, a low power explicit pulse triggered flip flop is discussed as a proper choice of low power applications and comparison with other flip flop architectures.

Abstract: In a country like India, whose economy is mainly based on agriculture and the climatic conditions which are isotropic, we are still not able to make full use of agricultural re-sources. The main reason is scarcity of water. Another very important reason of this is due to un-planned use of water as a result of which a significant amount of water goes into waste. In the modern irrigation systems, the most significant advantage is that water is supplied near the root zone of the plants. But the modern day drip irrigation systems had not been automated. The problem incurred was the inability to adopt labour for just switching on/off the valves and one more problem unnoticed was closing of valves since it was a huge area. So, a low cost automation that is user friendly for uneducated farmers was required to handle the system. This situated can be improved if we use automatic controller based closed circuits of Mini-sprinkler irrigation system in which the irrigation will take place only when there will be intense requirement of water. The valves can be easily automated by using controllers and solenoids. Automating farm or nursery irrigation allows farmers to supply the right amount of water at the right time, regardless of the availability of labour to turn valves on and off. So, the implementation with a low cost processor will be able to sense the moisture content of the soil level and irrigate the crops. Use of wireless module and communication system like Zigbee would solve the problem of expensive cabling involved. An alarm or any signal would indicate if the connection between the sensors and the control system is lost to intimate the user so as to troubleshoot the problem. Effective programming would further improve the case.

DOI: 10.17148/IJIREEICE.2015.3214
Abstract: Image compression plays a crucial role in medical imaging allowing efficient storage and transmissions by reducing the amount of data required to represent the digital image. The main goal is to achieve higher compression ratios and minimum degradation in quality. To decrease the storage space, the use of different compression techniques is justified by some medical imaging modalities generate the volume that of data which will be increasing. Different medical images like X-ray angiograms, magnetic resonance images, Ultrasound and computed Tomography are used in the medical image compression techniques. In medical applications it is required to conserve the diagnostic validity of the image requires the use of lossless compression methods, producing low compression factors. For medical data, lossless compression is preferred to the greater gains of lossy compression, in the interest of accuracy. . A set of experiment has been performed for the analysis of the proposed work on the several DICOM medical images and it has been observed that the DWT, DCT and Huffman coding has higher compression ratio than the hybrid model. The proposed method gives better quality of image that includes high PSNR and CR as well as low MSE. The proposed medical „DICOM images compression scheme‟ is based on Hybrid DWT, DCT and Huffman coding techniques.

E.J.Niranjana Devi, P.Subha Karuvelam
DOI: 10.17148/IJIREEICE.2015.3217
Abstract: The Matrix Converter (MC) is capable of synthesizing variable magnitude and frequency output voltage while maintaining desired input power factor and it eliminates the need for DC link capacitors. This has led to the broad classification of matrix converters as indirect matrix converter (IMC) on the presence of a DC link and Direct MC(DMC) based on the absence of a DC link. In this paper, a three phase IMC is used to drive the three phase BLDC motor, which consists of a Current Source Rectifier (CSR) and a Voltage Source Inverter(VSI) connected via a fictitious DC link. Space-vector modulation is used to generate the gate pulses for the CSR and the gate pulses for the VSI are generated based on the rotor position of the BLDC rotor. The PI speed controller is used hereto improve the speed response of the motor and a PI current controller is used to minimize the torque ripples. The IMC fed BLDC motor is simulated using Matlab software package and the results of open loop and closed loop systems are compared and validated.
Keywords: Indirect matrix converter (IMC), Permanent magnet Brushless DC Motor, PI Controller, Current source rectifier(CSR), Voltage source inverter(VSI), Space Vector PWM(SVPWM).

DOI: 10.17148/IJIREEICE.2015.3218
Abstract: A new technique of designing a robust PID and Polynomial controller for DC motor speed control is proposed. The proposed approach poses the design problem as fixed structure robust controller and mixed sensitivity H∞ method. Performance weights are designed based on the closed-loop objective and performance requirements which are normally applied in H∞ optimal control. Further Genetic Algorithm (GA) is adopted to solve the optimization problem for finding the optimal controller by selection of PID and polynomial parameters. Usually in literature, comparison has been carried out based on time domain performance indices; whereas, in this work, mixed sensitivity H∞ method is considered as the fitness function for the GA techniques in order to assess the robustness of the designed system. Also, comparison of fixed structure PID and Polynomial controller is done for DC motor speed control. The proposed technique can solve the problem of complicated and high order controller of conventional H∞ optimal control for practical use.

Power Compensation using Fuzzy Logic Based For Grid Interactive PV System
V.Dega Rajaji, D.Akhila John, D.Amulya John
DOI: 10.17148/IJIREEICE.2015.3220
Abstract: Photovoltaic (PV) cell characteristics are highly nonlinear that gives single Maximum Power Point (MPP) on P-V curve under uniform insolation condition. The characteristics and hence MPP point changes with the variation in insolation and temperature. In order to extract a maximum power from PV array, a fuzzy based MPP tracking algorithm is proposed. The algorithm accepts single input that is slope of P-V curve and generates the duty ratio as an output that operates the boost converter to track MPP. The algorithm gives faster convergence by applying variable step in duty ratio and gives accurate MPP. The two stage grid interactive PV system described in this paper supplies active power as well as provides harmonic and reactive power compensation. This additional feature increases the effective utilization of PV inverter and increases the overall efficiency of the system. The simulation results validate the performance and stability of the grid interactive PV system using the proposed algorithm for active current injection as well as harmonics and reactive power compensation.

Abstract: Signature is a behavioral trait of an individual and forms a special class of handwriting in which legible letters or words may not be exhibited. The purpose of this paper is to design a new system to make the verification of signatures size and angle invariant for cheque system. The invariance can be achieved by scaling and rotational manipulations on the target image. That is the number of crests, toughs and curves remains the same irrespective of the size and orientation of the image. The ratio between consecutive crests and troughs there by remain the same and hence can be used to determine the genuineness of a signature. This system will be used in financial and business to automatic signature verification. It also includes the verification of the account number and amount on the cheque using OCR (Optical Character Recognition) and finds out if the cheque is cleared or bounced.

Shreedevi Subramanya, Praveen J, Raghavendra Rao A
DOI: 10.17148/IJIREEICE.2015.3225
Abstract: Analog-to-digital converters (ADCs) are key design blocks and are currently adopted in many application fields to improve digital systems, which achieve superior performances with respect to analog solutions. Application such as wireless communication and digital audio and video have created the need for cost effective data converters that will achieve higher speed and resolution. Comparator is one of the main building blocks in most analog-to-digital converters. Many high speed analog to-digital converters, such as flash ADCs, require high-speed, low power comparators with small chip area. In low power, area efficient, and high speed analog-to-digital converters we need dynamic regenerative comparators to increase speed and power efficiency. In this paper, a new dynamic comparator is proposed, where the circuit of a low voltage low power double tail comparator is modified for area efficient and double edge triggered operation. This paper provides a comprehensive review about a variety of comparator designs - in terms of performance, power and delay using Cadence Virtuoso CMOS 180-nm technology.

Abstract: Since from 1980’s, the US military has been working on SDR to increase the ease and flexibility of communication within and between the services. Different forces present at that time used dozens of different radios. Most of the radios could only communicate with the other radios of same kind. Software Defined Radio (SDR) offered the promise of not only interoperating with all existing radios, but also allowing those radios to communicate with each other. Just as important, SDR has enabled future communication systems to be implemented on already deployed hardware. Software Defined Radio (SDR) is a radio communication system where components that have been typically implemented on hardware are instead implemented by means of software on a personal computer or embedded system. While the Software defined radio is not new concept, the rapidly evolving capabilities of digital electronics render practical many processes which used to be only theoretically possible. A software defined radio (SDR) allows for digital communication system to easily adopt more sophisticated coding and modulation techniques, which is extremely important in meeting the ever increasing demands of the wireless communication [7].

DOI: 10.17148/IJIREEICE.2015.3229
Abstract: Cancer is one of the common diseases occurring among the people all over the world. It can be due to various reasons such as different habitats, environmental disorders etc. Cancer being detected at early stages can save millions, if effective treatment is provided. It can cause damage to any part of body. Breast cancer occurs when breast cells divide rapidly to form a lump or mass known as a tumor. The detection of the breast cancer is a challenging problem, due to the structure of the cancer cells. This project presents a threshold method, for segmenting mammographic images to detect the Breast cancer in its early stages. The threshold will be determined by clustering an image based on row and column separation. The manual analysis of this samples are time consuming, inaccurate and requires intensive trained person to avoid diagnostic errors. The segmentation results will be used as a base for a Computer Aided Diagnosis system for early detection of cancer from mammographic images which will improves the chances of survival for the patient. Furthermore, the probability of the tumor to identify its type is also taken by us i.e. benign, suspicious or malignant.

Abstract: Most cells in the body grow and then divide in an orderly way to form new cells as they are needed to keep the body healthy and working properly. When cells lose the ability to control their growth, they divide too often and without any order. The extra cells form a mass of tissue called a tumor. Brain tumors are abnormal and uncontrolled proliferations of cells. Segmentation methods used in biomedical image processing and explores the methods useful for better segmentation. A critical appraisal of the current status of semi automated and automated methods are made for the segmentation of anatomical medical images emphasizing the advantages and disadvantages. In this project we detect the brain tumor & classify the stages of the tumor by using testing & training the database. Segmentation for testing purpose is done by spatial FCM used.

Abstract: In current scenario, the demand for wireless communication is increasing drastically. A wireless system has number of advantages over its wired counterpart including allowing a communication link to be set up quickly without the difficulty and expense of installing data transmission lines. The wireless communications industry has experienced an explosive growth in the last decade. One of the most promising spectrums an efficient technique is multiple-input- multiple-output (MIMO) systems that employ multiple transmits and receives antennas. The multiple inputs multiple outputs (MIMO) radar system transmits M antennas and receives N antennas. In this proposed system first step can be initially derive the diversity gain for a signal present versus signal absent scalar hypothesis test statistic and for a vector signal present versus vector signal absent hypothesis test. The MIMO radar system, used to detect a target composed of Q random scatterers with possibly non-Gaussian reflection coefficients in the presence of possibly non-Gaussian clutter-plus-noise. Diversity gain for the MIMO radar system is dependent on the cumulative distribution function (CDF). In this maximum possible diversity gain can be achieved for non orthogonal waveforms.
