The current personal identification strategy does not provide high amount of privacy to the individual databases and is not convenient and also very time consuming. In my work, I have improved the privacy of an individual to higher level. In the structure, three sorts of organizing scores, which are exclusively procured by the left-hand PALM_PRINT planning, right PALM_PRINT plans and intersection organizing between the left request and right get ready PALM_PRINT, are interlaced to settle on an official decision. Palm prints of both hand of a person are to some degree connected and it enhances the exactness of character distinguishing proof.

A series of laboratory model test has been carried out to investigate the bearing capacity of the square footing resting on reinforced sand bed. The geo-grid as a reinforcement material has been used. In the present study an attempt has been made to study the bearing capacity of square footing on sand reinforced bed. The effect of different parameter like the depth of the upper most layer of reinforcement from the base of the model footing (u), for different densities of the sand (γ = 1.60, 1.70, and 1.80gm/cc) the test has been carried out. Three numbers of layers, has been fixed. The test results showed that the beneficial use of geo-grid reinforcement in terms of increasing in the bearing capacity and minimizing the settlement, at an optimum depth of reinforcement, however for the higher density of the soil gives maximum bearing capacity. Therefore, for effective utilization of geo-grid reinforcement, the optimum depth should be (u = 0.40B) which is found to be good agreement with the past researchers, and the foundation soil should be in higher density.

In this experimental investigation study of the influence of magnesium sulphate attack on Slurry Infiltrated Fibrous Concrete (SIFCON) using hooked ended steel fibres is carried out. Similarly the replacement of cement with fly ash in three different proportions as 5%, 10%, 15%, and replacement of fine aggregate with quarry dust in three different proportions of 5%, 15% and 25% was done. The main goal is to improve the compressive strength of concrete. To optimize this serious defect partial incorporation of fibers is practiced. In this study we have induced 5% and 6% fibers of the total volume of the specimen. For the study, the cubes were kept immersed in MgSO4 for 28 days and the attack of Sulphate on concrete was studied. Mechanical test such as compression test was carried out on standard size of cubes28 days. In this investigation it was observed that the compressive strength was decreased of SIFCON and there was no change in dimensions, any gain or loss of weight to the SIFCON specimens which were under sulphate attack after 28 days of acid curing.

Database is a collection of large set of data and information which are organized so that it can be accessed efficiently for knowledge discovery. Many real world applications uses open databases which are available in the internet to extract information based on their needs. The relational databases which are freely available are used by research community for mining new information regarding to their research works. These databases are vulnerable to security issues related to ownership and data tampering. The reliability of the data source must be verified before using it for any research or application purpose. In order to ensure ownership and reliability, watermarking is done to the data. When watermark is embedded to the database it reduces the quality of the data thereby making it unfit for information retrieval .In order to avoid this scenario reversible watermarking is deployed which preserves data quality by recovering the original data along with data security .There are many effective approaches that performs reversible watermarking to ensure ownership along with data recovery. But the main problems with these techniques are, they only focus on numerical databases. Due to this, many of the databases which contain textual data cannot be watermarked with the existing approaches. In order to watermark the textual database an efficient method is proposed here, that uses the Unicode and ASCII value of the alphabets to watermark the textual data. It encodes the textual data with numeric values but retrieves the original textual data at the receiving end. Since a numerical value replaces the textual data field during transmission it makes it difficult for the attacker to retrieve the original information held in the database.

Classification and detection of brain tumor is important to diagnose the medical image processing of the MRI brain images. Magnetic resonance imaging (MRI) is used by many radiologists in order to test the internal structure of the human body and to provide the clear picture of the image. It is very important to identify the tumor in human brain due to its complexity and variation in the cell characteristics like its gray scale intensities, size, shape and location of the tumor region. Since misclassification occurs during the classification of the brain tumor due to more diversity of the tumor region and tumor edges. The various techniques have been surveyed to decrease the cost and time and to determine the better classification accuracy. The variety of brain tumor images is taken in order to classify them as benign and malignant.

Effects of applied of EHD on the performance of vapour compression refrigeration system are experimentally investigated to present applicability of the EHD technique. In the experimental work the condenser section is modified only. The refrigerant is cooled by dielectric fluid (transformer oil). Tests were performed at 21-22 LPH of refrigerant flow and at different electrical field strengths (0-250 V), while average saturation temp was 54°C and 6°C. Experimental results demonstrate a remarkable potential in utilizing EHD to enhance condensation heat transfer. It is concluded that the enhancement is driven by the effective removal of the condensate through EHD induced liquid extraction and dispersion phenomena. For the presence of the electrodes, the experimental results indicate that the maximum heat transfer rate obtained is 1.092040 kJ/sec and COP actual obtained is 4.98 which is 3 to 4 times more than without the EHD effect. This technique can be utilised effectively to the refrigeration system to have better COP and also size of condenser as well as evaporator can be varied.

An effort has been taken to study the performance and emission characteristics of a Variable Compression Ratio (VCR) diesel engine fuelled with biodiesel (Rapeseed Oil Methyl Ester-ROME) using EGR. Experiments are conducted on a single cylinder, four-stroke diesel engine powered by Variable Compression ratio with 0%, 5%, 10 % and 15% EGR keeping the load constant i.e. 12kg. Various engine performance parameters such as Brake thermal efficiency; Specific Fuel Consumption, Mechanical efficiency etc. were calculated from acquired data. The engine performance and efficiency obtained with biodiesel was less as compared to diesel which can be attributed to lower calorific value of biodiesel. At CR-18, the performance and emission parameters for ROME are better when compared to other compression ratio. This indicates the feasibility of using ROME as an alternative fuel for diesel. With application of EGR the NO emissions were considerably reduced. However using EGR at high levels result in certain penalties. It increases CO and HC emissions and also affects the performance. The purpose of this Paper is to determine the possibility of using biodiesel as an alternative fuel for petro diesel and effect of EGR on emission Characteristics of Engine.

All machines, vehicles and buildings are subjected to dynamic forces that cause vibration. Most practical noise and vibration problems are related to resonance phenomena where the operational forces excite one or more modes of vibration. Modes of vibration that lie within the frequency range of the operational dynamic forces always represent potential problems. Mode shapes are the dominant motion of a structure at each of its natural or resonant frequencies. Modes are an inherent property of a structure and do not depend on the forces acting on it. On the other hand, operational deflection shapes do show the effects of forces or loads, and may contain contributions due to several modes of vibration. This project deals with optimization and modal analysis of the upper arm suspension of double wishbone suspension. Upper arm has been modeled using CATIAV5, meshing will be done in HYPERMESH12.0, and ANSYS will be used for post processing. Boundary forces will be calculated. Static analysis will be done which is needed to be done for optimization, low stressed region will be identified and material will be removed from that region. Re-analysis (modal) will be done on the modified model. Once we get desired results, model will be fabricated and tested with FFT analyzer to check for response of the arm. Suspension system of an automobile plays an im1portant role in ensuring the stability of the automobile. Control arm plays major role in independent suspension system. It is generally made of forged steel which has considerable disadvantages such as weight, cost etc.

The demand for bigger, faster and lighter moving vehicles, such as ships, trains, and buses has increased the importance of Efficient structural arrangements. In principle two approaches exist to develop efficient structures: either application of new materials or the use of new structural design. A proven and well-established solution is the use of composite materials and sandwich panels. In this way more strength to weight ratio and minimum weight can be obtained. The sandwich structures have potential to offer a many range of attractive design solutions. In addition to the obtained wt. reduction, these solutions can often bring space savings, fire resistance, noise control and improved heating and cooling performance. Laser-welded metallic sandwich panels offer a number of outstanding properties allowing the Designer to develop light and efficient structural configurations for a variety of applications. These panels have been under active Investigations during the last lots of years in the world. Out okumpu has been participating in several collaborative projects in this area. In Finland the research related to all steel sandwich structure was initiated in 1988 in the Ship Laboratory of Helsinki University of Technology.
