Umhara Rasool, Sanna Mairaj, Tamanna Nazeer, Suhaib Ahmed
Abstract - With the advent of digital information age there has been ever increasing demand of intensive multimedia based web applications, efficient techniques for encoding of images and signals. There are stronger efforts to develop better compression techniques with the sole objective to produce high compression performance while minimizing the amount of image data. Image compression is a technique to reduce redundancy and irrelevancy of image data to enable its efficient transmission and storage. With the help of image compression techniques, we can store more images in a given amount of disk or memory space. We can have lossy or lossless image compression depending upon the application. However, there is degradation in the quality of compressed image in comparison to original image in lossy compression techniques (discrete cosine transform, differential pulse coded modulation etc.). Lossless compression techniques do not deliver high enough compression ratios but exhibit better quality of reconstructed images in comparison to lossy techniques. Wavelet algorithm is one of the indispensable technique to achieve compression while fulfilling approximately all the challenges. It enables multi resolution analysis of data. In this paper, wavelet based compression techniques are studied in detail and a comparison of performance is made in terms of image quality metrics viz. PSNR, MSE, BPP and Compression ratio. Discrete wavelet transform is easier to implement in contrast to continuous wavelet transform. In addition to above, it also provides sufficient information for analysis and synthesis of images with a significant reduction in the computation time. In this paper, Haar, Daubechies, Biorthogonal, Coiflets and Symlet wavelets have been employed to an image and thereof results obtained are analyzed in terms of image quality metrics. In addition to it, a comparison of the image quality has been performed by using four wavelet-based encoding algorithms namely Set Partitioning in Hierarchical Trees (SPIHT), Embedded Zero Tree Wavelet (EZW), Wavelet Difference Reduction (WDR) and Adaptively Scanned Wavelet Difference Reduction (ASWDR). This paper is a guide to the developers to choose better wavelet compression system for their particular applications.
3 A Novel Technique for Detection of Copy Move Forgery Using MSER Features
Kanica Sachdev
Abstract - Digital image forgery detection is one of the most significant fields in image forensics. It refers to the editing or alteration of the image contents. Since an image may be presented as a legal proof of evidence, thus verifying its originality is of utmost importance. Recent improvements in image capturing devices and image editing softwares have made the process of forging images simple. The most common type of image forgery is copy move forgery. In this, a part or block of an image is copied and then pasted on the same image. The pasted area may be scaled or rotated to make the process of forgery detection difficult. The proposed technique uses MSER features to detect forgery in images. MSER features are stable and invariant to affine transformations. They are used in a number of applications for blob detection. In the introduced method, the extracted MSER features from the image are matched to find the forged areas in the image. The matched points correctly identify the copied and pasted areas of the altered image. The proposed method even detects forgery in the presence of rotation and scaling of forged area. It is a low complexity algorithm that is shown to perform efficiently on standard dataset.
4 A Review of Grid Connected Photovoltaic Systems
Tamanna Nazeer, Swastik Gupta, Shashi Bhushan Kotwal
Abstract - Due to ever increasing power demand and the environmental concerns associated with it, the interest in distributed energy generation systems (DG systems) based on solar energy is increasing. Using Photovoltaic (PV) modules, solar energy can be directly converted to electrical energy. In PV modules, the output voltage is DC and has low amplitude. In order to be connected to the grid; the PV modules output voltage should be boosted and converted into an AC voltage. This task can be performed by one or more conversion stages. Different topologies are used for this purpose. Also voltage power characteristic of PV array is non-linear and the power characteristic varies with the level of solar irradiation and temperature therefore making the extraction of maximum power from the PV panel a complex task. Thus, in order to overcome this problem, several methods called Maximum Power Point Tracking (MPPT) techniques for extracting the maximum power have been proposed in the literature and a careful comparison of these methods can result in important information for the design of these systems. This paper presents an overview of the existing power inverter topologies that have found practical applications for grid connected PV systems. In addition, paper presents a comparison of various power point tracking (MPPT) techniques serving as a convenient reference for future work in PV power generation.

8 Effect of Susceptor Heating on Joining of Metallic Pipes Using Microwave Energy
Dhirendra N Gamit
Abstract - Joining of Metallic pipes are a prime requirement in the industries such as processing, oil and automotive etc. Many pipe joining processes were reported by the researchers but the producing sound and eco friendly joint is a concern for the industries. In pipe joining, rejection and rework of joint is a major concern this leads to consequently consumes more productive time and loss of energy. It has been reported that microwave (MW) energy can be used for joining of bulk metals. Usage of microwaves energy for joining of bulk metals have revealed that the process is capable enough to produce joints with lesser processing time, eco-friendly and energy saving process and the joints exhibit better mechanical and metallurgical properties than conventional joining processes. The attempt has been made to join MS pipes using microwave hybrid heating technique. This paper reports joining of mild steel (MS) pipes using micrometric size (40 um) of nickel powder as an interfacing material in a multimode MW applicator at 2.45 GHz. Different susceptor such as Silicon carbide (SiC), Graphite and Charcoal have been analysed for the joining of pipes at 1400 and 900 W microwave power. In susceptor heating, charcoal shows most efficient susceptor material which helps to produce good pipes joint at 900 W. A ceramic fixture was designed for holding and processing the required joints in MW applicator. The basic principles involved in the MW pipe joining process have been discussed. Further, initial experimental observations have been analyzed and results have been discussed.

11 Role of Hydraulic Fluid Pressure in Sheet Metal Forming
Dr.R.Uday Kumar
Abstract - The stamping of parts from sheet metal is a straightforward operation in which the metal is shaped or cut through deformation by shearing, punching, drawing, stretching, bending, coining, etc. Production rates are high and secondary machining is generally not required to produce finished parts within tolerances. This versatile process lends itself to low costs, since complex parts can be made in a few operations at high production rates. Sheet metal has a high strength-to-weight factor, enabling production of parts that are lightweight and strong. Hydroforming process is divided into two main groups; sheet hydroforming and tube hydroforming. Tube HydroForming (THF) is a process of forming hollow parts with different cross sections by applying simultaneously an internal hydraulic pressure and axial compressive loads to force a tubular blank to conform to the shape of a given die. Geometry of die and workpiece, initial tube dimension, tube anisotropy, and internal pressure are of the important parameters in this process .With the advancements in computer control and high-pressure hydraulic systems, this process has become a viable method for mass production, especially with the use of internal pressure up to 6000 bars. Tube hydroforming offers several advantages as compared to conventional manufacturing processes. Double-blank sheet hydroforming can be used as an alternative to sheet hydroforming with a die, because in both methods the sheet metal is forced against the die by the liquid medium. However, in double-blank sheet hydro-forming, two parts can be produced in one production cycle, which increases productivity. This process potentially allows the forming of two different materials and/or two different sheet thicknesses in one production cycle. Doubleblank sheet hydroforming is the potential to be practical for the production of relatively small batches of parts.

M. Jayagopal, Gift Pon Lazarus D
Abstract - The production of 1 tons of cement liberates 755 kg of carbon-dioxide has leads to increase in global warming, the usage of cement is keep on increasing due to the construction of structures, which is necessary for a country to improve it's infrastructures. The usage of cement should be reduced by replacing it, now a day's industries are developing in a rapid manner and the by- products from it are disposing as a waste in dumping yards. Mainly three major mineral admixtures of fly ash, blast furnace slag, silica fume are treated as waste products. Fly ash material has been using in construction field for replacement of cement up to 35%. This project is to increase that percentage of replacement by a suitable waste material. To achieve all the three by products mentioned above are mixed in a proportion of 60%, 30%, 10% of blast furnace slag, fly ash, silica fume respectively. This combination will give better properties like standard cement then the individual replacement of byproducts. Then the cement manufacturing process is adapted for mixture by heating the mixture at a temperature of 1400oC, the clinker will form then the clinker is crushed and grained to get the fineness of cement. The mixture is tested for standard cement tests like specific gravity, consistency, initial and final setting time, loss on ignition, and chemical composition. The cement in concrete is replaced by obtained mixture by increment of 20% up to 100%. Then the concrete is tested for compression, split tensile, flexural strength test to find the performance of mixture in concrete.
