Palash Chandra Karmaker, A G M B Mustayen and Md. Mizanur Rahman
DOI: 10.17148/IJIREEICE.2016.4801
Abstract: The design of a microstrip patch antenna based on E-shaped patch for WiMAX application is presented. The proposed antenna is simulated by Electromagnetic simulator, XFDTD (Finite Difference Time Domain Method). The simulation result shows the antenna system resonates at 3.0 GHz frequency this is suitable for WiMAX application. The parameters are calculated for outer dimensions of the E-shaped microstrip patch antenna on the basis of line width to substrate thickness (W/h) ratio by considering loss less dielectric material (FR-4.8 Duroid material). The characteristic line impedance (Zo) and effective dielectric constant (εeff) are calculated by considering different values of W/h ratio like 2, 3, 4, 5, 6, 7, 8 and 9. The comparative statement among characteristic line impedance (Zo) and effective dielectric constant (εeff) with W/h ratio are presented. Return loss (S11), reflection coefficient and VSWR versus frequency plot are also presented.

DOI: 10.17148/IJIREEICE.2016.4802
Abstract: Voltage sag and voltage swell are two of the most important power-quality problems that encompass almost 85% of the distribution system power quality problems. The dynamic voltage restorer (DVR) is one of the modern devices used in distribution systems to protect consumers against sudden changes in voltage amplitude. In this paper, a multifunctional DVR control strategy is proposed along with Posicast and P+Resonant controllers. With the help of these controllers the transient response of DVR can be improved and also in DVR response, the steady state error can be eliminated.

DOI: 10.17148/IJIREEICE.2016.4803
Abstract: The cognitive radio is able to provide a wide variety of intelligent behaviours. It can monitor the spectrum and select frequencies that minimize interference to existing PU communication activity.When doing so,it will rely on a set of rules that define which frequencies may be considered,what waveforms may be used, what power levels may be used for transmission.This paper deals mainly with manet based routing protocols performance which greatly depends on availability and stability of wireless spectrum and also a crucial parameter that should not be neglected in order to obtain accurate performance measurements of cognitive radio network.The primary goal of any CR network routing protocol is to meet the challenges of the dynamically changing network topology and establish an efficient route between any two nodes with minimum routing load and bandwidth consumption.Here,we evaluate the performance and comparison of AODV, DSR, DSDV and OLSR routing protocols on the basis of various parameters such as packet delivery ratio, throughput and so on. Finally, select the best performing protocol for CRN networks based on different parameters.

DOI: 10.17148/IJIREEICE.2016.4804
Abstract: Providing security for the IOT environment is the major assessment carried out where the entire world is dependent on e-communication and assures the guarantee of communication without any error causing .In this project work, Raspberry Pi, an open source and a popular choice as the hardware platform for IoT - both devices as well as gateways, has been used. It is nowadays a trend and also a more appropriate path to choose open source software for implementation for the prototyping and study purposes in academia. As such Open SSL has been employed for configuring secure access of data at the device level as well as the library for the secure communication using the MQTT and CoAP protocols. Further, the project work also involves a study of different web access vulnerabilities and suggested remedies. Even when the latest version 2 of Raspberry Pi was employed the performance of the application with Open SSL vs. a standard desktop computer system is not comparable. Further optimization of the application or use of a 128-bit key based encryption could be the possible approaches for security implementations for embedded applications. The primary objective of this project aims at implementing security procedures for IoT based devices such as nodes (for ex raspberry pi) and gateways (for ex PC) using MQTT and CoAP protocol in an embedded platform. Project approaches at different layers of the ISO/OSI model for the security of end to end nodes and gateways through cloud.

Shipra Sharma, Kanika Sharma
DOI: 10.17148/IJIREEICE.2016.4807
Abstract: The main problem with fixed sink WSN network is energy hole creation near to the fixed sink node. This problem’s resolution is explored by distributing the energy consumption in many wireless sensors by using the mobile sink node concept. The mobile sink method of data gathering is much more efficient as compared to static sink design due to which it has attracted so much of attention in recent times. However, the path which the mobile sink follow while moving in the network area is the topic of extensive research. The optimization of the moving trajectory of mobile sink plays a vital role in making a WSN’s design energy efficient.

Mahesh S. Khande, A K Jhala, Manish Prajapati
DOI: 10.17148/IJIREEICE.2016.4811
Abstract: Voltage sags have always been a more threat to sensitive industrial and commercial electrical consumers, and deep sags with long duration time are usually more intolerable. In this paper, a new study of series-connected compensator is presented to mitigate long duration deep sags, and the solatium ability is highly improved with an unrivalled shunt converter structure acting as a parasitic boost circuit that has been theoretically analyzed. Additionally, the projected active voltage quality regulator is a cost effective solution for long duration sags that are lower than 50%of the nominal voltage as it is transformerless compared with the traditional dynamic voltage restorer. High operation efficiency is ensured by applying the dc-link voltage adaptive control method. Analysis, along with simulation and experimental results, is presented to verify the feasibility and effectiveness of the projected study.

A Design of Efficient Viterbi Decoder with High Speed Low Power Consumption for TCM Decoders
Vidiyala Mallika, B. Gajan
DOI: 10.17148/IJIREEICE.2016.4813
Abstract: High-speed, low-power design of Viterbi decoders for trellis coded modulation (TCM) systems is presented in this paper. It is well known that the Viterbi decoder (VD) is the dominant module determining the overall power consumption of TCM decoders. We propose a pre-computation architecture incorporated with T-algorithm for VD, which can effectively reduce the power consumption without degrading the decoding speed much. A general solution to derive the optimal pre-computation steps is also given in the paper. Implementation result of a VD for a rate-3/4 convolutional code used in a TCM system shows that compared with the full trellis VD, the pre computation architecture reduces the power consumption by as much as 70% without performance loss, while the degradation in clock speed is negligible.

DOA Estimation Using MOD MUSIC Method and Calculation of Signal and Noise Power
Bhawna Singh
DOI: 10.17148/IJIREEICE.2016.4814
Abstract: The DOA estimation algorithms are designed based on the ideal assumption where the antenna arrays are free from imperfect conditions. But in practical situation, ideal conditions are extremely difficult to obtain and thus due to imperfect conditions, the performance of DOA estimation will be severely degraded. Results of classical methods like MUSIC or Beamforming for direction of arrival estimation degraded when sources are close or coherent or having low SNR. Based on the investigation to classical DOA algorithm (MUSIC and Improved MUSIC), a mod-MUSIC estimation algorithm is proposed which makes full use of signal subspace and noise subspace characteristics. It has good performance in imperfect condition and compare this algorithm with classical algorithms in different conditions.

Industrial Explosion Control through Webpage
Abhisekhar Reddy Madireddy, Vijaya Durga Madireddy, Radheswar Reddy Madireddy
DOI: 10.17148/IJIREEICE.2016.4815
Abstract: The paper describes the design and implementation of Industrial Explosion Control through Webpage. Fire extinguishers play a crucial role in protecting the environment due to their proven ability to fight fires while they are at their very early stages. The availability of accessible and working fire extinguishers assures that the highest possible percentage of fires will be controlled with the minimal environmental impact possible. Replacing the inefficient and carbon-intensive manual extinguisher inspection methodology with electronically monitored extinguishers will have significant positive impacts on the environment. Hence we propose an SMS based Fire indication system which will be very useful in remote locations where human interaction is limited. Such systems are useful in mines, industrial areas, factories etc. So SMS based Fire indication system helps to monitor locations and alert during fire that occurs in night time. Generally 90% of fire damages occur due to lack of early fire detection. A fire attack is usually silent and people will know about fire only when it has spread across a large area. SMS based Fire indication system gives warning immediately to multiple mobile numbers and hence remedy actions can be taken quickly. This helps to prevent major damages and losses created by a fire accident. After getting the SMS through GSM and the machine can be controlled using the Webpage developed. In this paper we have taken a DC motor as prototype for Industrial machines. Fire detector sensor, Motor driver IC, GSM modules are used in the working prototype.

The Effect of Excitation System on Synchronous Generator Transient Stability
Mansour Babiker Idris, Ali Juma Elzubia
DOI: 10.17148/IJIREEICE.2016.4817
Abstract: The consequences of electric power outages impose studies of models that combine representations of the various components such as generators, loads, and networks in the power system. It is clear that the main role of the excitation system is supplying the field winding of the synchronous generator with the dc current for generation, as well as voltage and reactive power control to maintain a constant terminal voltage during the all loading conditions, and synchronous generator stability improvement. But addition of the excitation system with high response causes a large oscillation for the power system, because it is adding a negative damping torque. This makes a shift for the roots of motion equation from the negative part to the positive part. This paper discusses the effect of adding this type of excitation system on synchronous generator stability. A system having a synchronous generator connected to an infinity bus is discussed as case study during a sudden and continuous disturbance, and the simulation is done using MATLAB.

Jyoti Purohit, Naveen, Smita Pareek
DOI: 10.17148/IJIREEICE.2016.4818
Abstract: From past so many years, power production from solar photovoltaic has received expansion. It has lots of gratifications compared to other non-renewable energy sources. Also solar photovoltaic converts sunlight directly into electricity. However, the major snag in using solar photovoltaic is the effect of partial shading on it. The effect of partial shading on solar photovoltaic systems is such severe that it need not to cast on whole photovoltaic array to ruin its performance but if shading appears on even a small portion of array it will diminish the output of whole photovoltaic system to almost zero. In this paper, all the techniques that have been reported in literature to mitigate the effect of partial shading on solar photovoltaic systems are mentioned and compared. It is envisaged that this work will be a source of valuable information for photovoltaic researchers and professionals working in this area.

Speech Security System for Electrical Line Man
Ashutha, Ankitha K
DOI: 10.17148/IJIREEICE.2016.4820
Abstract: In the last decade various speech technologies like automatic speech recognition (ASR), Voice response systems and another similar system have considerably matured. These systems rely on the security of lineman working with power lines. At transmitter end the software asks the user to enter the password to confirm the person‟s credibility. If found to be correct it prompts the user either to turn „ON‟ or „OFF‟ the power system. In case if the system is now turned „ON‟ then microcontroller first sends a warning signal using the RF wireless transmitter. A voice recognition module is interfaced to the microcontroller to enter the password. If the password entered is correct, then only the line can be turned ON/OFF. The main aim of this paper is to design and develop a life line saving security system for the line man who works on high voltage lines. In this project we are designing and developing a wireless security system using the speech processor in the real time environment.

Abstract: Medical records are extremely sensitive patient information and require uncompromising security during both storage and transmission. In this paper a multi secure and robustness of medical image based steganography scheme is proposed. The proposed technique provides an efficient and storage security mechanism for the protection of digital medical images. We proposed a viable watermarking technique using Discrete Wavelet Transform (DWT) to protect the MRI medical image into a single container image. At first the given image was resized and undergo watermarking using the svd and alpha blending and then it is applied with Arnold transformation to form scrambled image and recovered finally by descrambling using Arnold transformation and inverse svd on the obtained image The quality of the recovered medical image showed acceptable visual quality. It is observed that the quality parameters are improved with acceptable PSNR compared to the existing algorithms.

DOI: 10.17148/IJIREEICE.2016.4824
Abstract: High speed and low power utilization is critical configuration objectives in VLSI design circuits. Digital multipliers are most important functional unit. The major constraints for delay in any VLSI circuits are latency and throughput .The negative bias temperature instability (NBTI) effect happens when a pMOS transistor is under negative bias (Vgs= -VDD) increasing the threshold voltage of pMOS transistor and decreases the speed. A comparative phenomenon is done for nMOS, positive bias temperature instability, happens when an nMOS transistor is under positive bias. Both impacts will reflect on the performance of transistor speed, and in the long term, the system may fail due to violation of timing therefore in order to maximize the power consumption and delay ,multiplier with adaptive hold logic is used ,the multiplier is able to provide high throughput through variable latency and can adjust the AHL circuit ti mitigate performance degradation that is due to the aging effect . Additionally, the proposed design can be connected to a segment or column bypassing multiplier. The exploratory results demonstrate that our proposed design with 16 × 16 and 32 × 32 section bypassing multipliers can accomplish up to 62.88% and 76.28% execution change, respectively, contrasted and 16×16 and 32×32 fixed -latency section bypassing multipliers. Besides, our proposed design with 16 × 16 and 32 × A32 column bypassing multipliers can accomplish up to 80.17% and 69.40% performance improvement as compared with 16×16 and 32 × 32 fixed-latency row-bypassing multipliers. Furthermore we removed the tristate buffer from the column -bypass multiplier. With the goal that we can decrease the gate count and enhance the efficiency and speed and reduce the power consumption.

Abstract: Low-power is a basic prerequisite for versatile media gadgets utilizing different sign handling calculations and structures. In most interactive media applications, the last yield is translated by human detects, which are not great. This blocks the need to deliver precisely remedy numerical yields. The field of surmised computing has gotten critical consideration from the research group in the previous couple of years, particularly with regards to different signal processing applications. Picture and video pressure calculations, for example, JPEG, MPEG, and various other formats are especially appealing contender for inferred figuring or surmised computing, since they are tolerant of registering imprecision because of human indistinctness, which can be misused to acknowledge exceedingly control productive especially in power efficient usage of these calculations. Be that as it may, existing surmised designs regularly settle the level of equipment estimation statically and are not versatile to information. For instance, if an altered induced equipment arrangement is utilized for a MPEG encoder in a fixed level of guess, the yield quality fluctuates extraordinarily for various info recordings. This paper addresses this issue by proposing a reconfigurable surmised construed design for MPEG encoders that advances power utilization with the objective of keeping up a specific Peak Signal-to-Noise Ratio (PSNR) edge for any video. In new design, we plan reconfigurable adder/subtractor segments (RABs), which can balance their level of guess, and subsequently coordinate these pieces in the movement estimation and discrete cosine change modules of the MPEG encoder. Note that in spite of the fact that the proposed reconfigurable surmised engineering is displayed for the particular instance of a MPEG encoder, it can be effectively reached out to other DSP applications.

DOI: 10.17148/IJIREEICE.2016.4828
Abstract: Solar observation is the scientific endeavour of studying the Sun and its behaviour and relation to the Earth and the remainder of the Solar System. The life on earth is driven by the sunlight incident form the atmosphere. Therefore climate is critically sensitive to the solar activity. To receive solar radiation data acquisition extended- Compound Astronomical Low-cost Low-frequency Instrument for Spectroscopy and Transportable Observatory (e- CALLISTO) system was installed. This paper represents the brief review of sunspots, solar flares, solar wind and solar radio burst. Solar radio observations are relevant to such phenomena because they generally originate as events in the solar atmosphere, including flares, coronal mass ejections and shocks, that produce electromagnetic and particle radiations that impact the Earth. Low frequency solar radio emission arises in the solar atmosphere at the levels where these events occurs. We can use frequency as a direct measure of density and an indirect measure of height in the atmosphere. The main radio burst types are described. Solar burst can damage satellites. Very large flares can even create currents within electricity grids and knock out energy supplies.

DOI: 10.17148/IJIREEICE.2016.4829
Abstract: In this paper, a static var compensation scheme is proposed for a cascaded two-level inverter-based multilevel inverter. The topology uses standard two-level inverters to achieve multilevel operation. The dc-link voltages of the inverters are regulated at asymmetrical levels to obtain four-level operation. A simple static var compensating scheme using a cascaded two-level inverter-based multilevel inverter is proposed. The topology consists of two standard two-level inverters connected in cascade through open-end windings of a three-phase transformer. The dc-link voltages of the inverters are regulated at different levels to obtain four-level operation. The simulation study is carried out in MATLAB/SIMULINK to predict the performance of the proposed scheme under balanced and unbalanced supply-voltage conditions. A laboratory prototype is developed to validate the simulation results.

Identification of exudates using an image processing algorithm designed for early diagnosis of diabetic retinopathy
Monika Gupta, Dr. D.V. Jadhav
DOI: 10.17148/IJIREEICE.2016.4831
Abstract: One of the most primitive and common symptoms of diseases leading to loss of sight among individuals are exudates. Diabetic retinopathy is considered as a key root of blindness, particularly among working-age adults. The extent of retinopathy is extremely correlated with the exudates. Definite areas of the retina in eye with prevalent conditions are to be photocoagulated by laser techniques to impede the disease progress and avert blindness. To summarize the areas relies on outlining the lesions and the anatomical composition of the retina. In this dissertation work, we endow with a new biomedical feature extraction technique for blood vessels that encourages the exudates detection in funds images useful for diagnosis of retinopathy. The technique proceeds with an edge detection algorithm which yields segmented image as an input. Then the novel feature-based algorithm has been employed to detect the features of blood vessels properly. This algorithm is regarded as the feature extraction key for a retinal blood vessel and considers its width range, intensities as well orientations for the function of selective segmentation. Because of its bulb- shape and its colour resemblance with exudates, the optic disc can be extracted by means of the common Hough transform technique. The extracted blood vessel tree and optic disc could be excluded from the over segmented image to acquire an initial estimate of exudates for primary diagnosis. The eventual estimation of exudates can then be achieved by morphological reconstruction based on the appearance of exudates in retinal images.
