Design and Simulation of Audio Watermarking using Empirical Mode Decomposition for Copyright Protection
-Pragathi T L ; Meghashree A C
Digital watermarking is drawing attention a new method for protecting multimedia content from illegal copying. In this paper, we present a alternative audio watermarking procedure to provide copyright protection to the digital audio by modifying audio samples directly by making use of algorithm called Empirical Mode Decomposition (EMD). The original audio signal is sampled at 44.1 kHz to split it into non-overlapping frames. These frames are further decomposed by EMD adaptively into intrinsic oscillatory mono-component signals known as Intrinsic Mode Functions (IMFs). The digital watermark along with synchronization codes are embedded into the last IMF extrema. This is low frequency mode, stable under different attacks and preserving the audio quality of host signal. Based on the simulations, robustness of hidden watermark is demonstrated for different attacks such as noise, filtering, compression, cropping, resampling and re-quantization.. It is seen that the data embedding rate or payload of the algorithm is 46.9-50.3 bits per second. Read More...

-Rinku N. Patel ; Manish I. Patel
Low density parity check (LDPC) codes are adopted in many applications due to their Shannon limit approaching error correcting performance. In this paper, we analyze the Bit Error Ratio (BER) performance of LDPC codes with different codeword length and different number of iterations over Additive White Gaussian Noise (AWGN) channel. The encoding of LDPC codes is done with standard method and it is implemented using MATLAB. Codewords have been constructed for code rate 1/2. LDPC codes can be decoded using iterative decoding algorithm to improve the performance. Here, the min-sum decoding algorithm is implemented and desired simulation results were obtained using MATLAB. The min-sum algorithm is mathematically equivalent to the sum-product algorithm and it greatly reduces the computational complexity of sum-product algorithm.

Analysis of Different Geometry of Flywheel used in Punching Press
-Rahul L. Berani ; Ass.Prof.Jayvir Shah
A flywheel is an inertial energy-storage device. It absorbs mechanical energy and serves as a reservoir, storing energy during the period when the supply of energy is more than the requirement and releases it during the period when the requirement of energy is more than the supply. Mainly, the performance of a flywheel can be attributed to three factors, i.e., material strength, geometry (cross-section) and rotational speed. While material strength directly determines kinetic energy level that could be produced safely combined (coupled) with rotor speed, this study solely focuses on exploring the effects of flywheel geometry on its energy storage/deliver capability per unit mass, further defined as Specific Energy. Proposed finite element analysis and optimization procedure is used to find out smart design of flywheel geometry that have a significant effect on the Specific Energy performance.This paper specifically studies the most common five different geometries.

Performance analysis of Double pipe heat exchanger for electrohydrodynamic (EHD) effect
-Mr.S.V.Kumbhar ; Prof.H.M.Dange
Heat exchangers are widely used for efficient heat transfer from one medium to another. The heat transfer rate of any heat exchangers can be improved by heat transfer enhancement techniques. Generally, these heat transfer enhancement techniques can be divided into two groups: active and passive techniques. The active techniques require external forces e.g. Magnetic field, Electric field, acoustic or surface vibration etc. for heat transfer enhancement. On the other hand, the passive techniques require fluid additives or special surface geometries for heat transfer enhancement. Electrohydrodynamic (EHD) is one of the types of active heat transfer enhancement techniques. In this paper, performance of double pipe heat exchanger is studied and analyzed for elecrohydrodynamic effect. Read More...

Hierarchical Routing Algorithm for Energy Efficiency for Routing in WSN: A Survey
-Deeksha ; Jasbeer Narwal
In hierarchical routing protocols, cluster heads consume more energy since they are in charge of data aggregation as well as communications inside and outside of the cluster. The secondary objective of this work is to achieve a network with an optimum number of cluster heads at each round of data transmission. Although the focus of this work is on clustering, there are other techniques for reducing energy consumption such as topology control. A requirement in some algorithms for clustering is that the location of the base station should remain at a specific distance from the field. Therefore a major requirement in research is to develop a new method for the visualization of the residual energy data of WSN nodes to aid users in understanding the energy levels of WSN nodes deployed across the field.

High Performance and Low Power Level Converting Flip-Flop for Low Power Applications
-C. Kavitha ; Dr. K. Venkatachalam; V. Gowrishankar
In modern digital VLSI circuits, the clock system is composed of flip-flops. The Clustered voltage scaling (CVS) is an effective way to reduce power dissipation and improve the performance in digital integrated circuits. Level converting flip-flops (LCFF) are the critical elements in the CVS scheme. And then low power level-converting flip-flop with a conditional clock technique (CC-LCFF) has been designed and the circuit is simulated in 90nm CMOS technology on Mentor Graphics tool. Along this one the clock signal will be conditionally blocked when the input data don’t make any transition, and then the internal node redundant transitions are eliminated and the total power dissipation is decreased. But the CC-LCFF design suffers from issues like long discharge path and some extra internal node switching activity. Due to this, less quantity of power is dissipated in level converting flip-flop with a conditional clock technique. To further shorten the power dissipation, a Conditional Pulse-Enhancement technique and conditional discharge technique is proposed in CCER-LCFF. The proposed techniques also reduce the length of the discharge path and internal nodes switching activity in LCFF. It will be designed in 90nm CMOS technology on Mentor Graphics tool for evaluating the power dissipated and the outcomes are compared with an existing blueprint. Read More...

The purpose is to understand more clearly the problem-solving process in software engineering and to identify criteria that can be used to evaluate alternative software-driven problem-solving strategies for differing project requirements. A review of software process modeling is given first, followed by a discussion of process evaluation techniques. A taxonomy for categorizing process models, based on establishing decision criteria, is identified that can guide selecting the appropriate model from a set of alternatives on the basis of model characteristics and software project needs. These criteria can facilitate adaptability in the software process so that the process can be “altered or adapted to suit a set of special needs or purposes†.The factors that have contributed to the diversification of software process models have often been related to the expansion in goals and capabilities in the software industry.

Groundwater Levels and Lithology in the Junagadh District of Saurashtra, Gujarat
-Ms. Sujaya Magar ; Dr. M. S. Gadhavi
Over the past two decades, the growth dynamism in Gujarat agriculture come from input intensive land use and farm management practices, which resulted in over-exploitation of groundwater.But apart from this agricultural aspect, in this paper we have tried to focus the fluctuations of groundwater levels of Junagadh district of Saurashtra, Gujarat and correlate the same with the lithology. The region of Saurashtra is dominated by Deccan Trap rocks and some part of it by Quaternary milliolite. These basaltic rocks are devoid of primary porosity, however groundwater is available in large quantity mainly owing to secondary porosity that is inherent in weathered basaltic rocks due to profound columnar joints and vesicles at a shallow depth. The Quaternary milliolite with high porosity is found to occur around the coastal belts of Junagadh district of Saurahtra region. The groundwater levels in 145 number of observation wells of the study area have been analyzed , in the pre and post monsoon periods of around twelve years from the year 2002 to 2013 and correlation of groundwater fluctuations with respect to the lithology has been developed using GIS platform.

Load Flow Analysis on STATCOM Incorporated Inter-Connected Power System Networks Using Newton Raphson Method
-Kumar Praveen Kayalia ; Alok Kumar Singh
With the advancement of technology the demand of electrical energy has also increased. The demand of electricity has become the parameter of growth of a nation. An electrical utility company has to use its existing transmission capacity to feed the ever increasing demand of electricity, due to the transmission lines has to be operated near its thermal stability limit. Operating the lines in close proximity to or above thermal stability limits makes system vulnerable to faults moreover it also increases the losses in the system. One way to increase the transmission capacity of the system without operating it to its thermal stability limit is to provide reactive power compensation at various locations. Reactive power reparation improves the voltage profile of the system, increase the power transfer in the lines and reduce losses. STATCOM is one such device that is used for reactive power compensation. It provides reactive power compensation thereby improving the voltage profile of the system. In this thesis reactive power compensation is attempted using STATCOM. To study its effect Load flow study is performed on IEEE (Institute of Electrical & Electronics engineer) 5 bus, IEEE 14 bus and IEEE 30 bus with and without STATCOM and the results are then compared to show the effect of STATCOM on the system. Newton Raphson method is used for the load flow study of the system. Simulation is done using MATLAB (Matrix Laboratories). Read More...

Effect of Atmospheric Pressure Plasma on Pilling Propensity of Acrylic Fabrics
-Patel Kruti V ; Prof. Vaishali Shah; Prof. A. I.Thakkar
Plasma is the 4th state of matter and a gas becomes plasma when the kinetic energy of the gas particles equals the ionisation energy of the gas. When gas molecules reaches excited state, molecule breakdown takes place and collision between excited species takes place. In this state it behaves as a chemically very active environment and the surface interaction with organic substrates takes place[1]. Pilling is the ball like structures on the surface of the fabrics that are formed due to repeated abrasion. Synthetic fabrics especially knitted are likely to pill more because of smooth surface and higher tensile strength. . This paper focuses on application of plasma treatment and its effect on various types of acrylic fabrics. The treated and untreated fabrics viewed under SEM and pilling tests and tensile strength test were carried out. It was observed that plasma treatment makes the fibre surface rough and decreases tensile strength of fibre; thus reducing the formation of pills on the fabrics by increasing inter fibre friction and detaching the pills from the fabric surface.

Contingency Analysis in Power System and Remedial Actions
-Patel Niraj Hitendrabhai ; Thakkar Vishal C.; Hemant N. Raval
For practical system operation, apart from ensuring the satisfactory operation of the system at a particular operating condition, it is also equally important to make sure that the system operates with adequate level of security. Broadly, the term ‘security’ implies the ability of the system to operate within system constraints (on bus voltage magnitudes, current and power flow over the lines) in the event of outage (contingency) of any component (generator or transmission line). The goal of this power system analysis function is to give the operator information about the static security. Contingency analysis is used to calculate violations. In this paper presents contingency analysis of power system is to predict the line outage, generator outage and to keep the system secure and reliable. Whenever the maximum violation is occur in power system, that line and generator is outage element. So we find the maximum violation in the system network. For the generation, transmission, and distribution system, security can be assessed using contingency analysis. This paper describes the power flow analysis of power system network using Power World Simulator and estimating the real and reactive power flows, power losses in the entire network and phase angle using Power World Simulator. This paper shows the example on 6 bus power system which gives information of violations & remedial action to remove violations. In this paper, first contingency conditions are analyzed after that according to severity of contingency a real power flow performance index (PI) sensitivity based approach and the line outage distribution factor has been used to decide optimal location of series FACTS devices.
