Securing code dissemination is essential for many crucial military applications. Suppose the nodes are deployed in the military areas, the border sensor nodes are the more sensitive nodes. The border sensor nodes need to do some special tasks compared to other intermediate sensor nodes. So the code dissemination to be sent to the border nodes will be different from that of intermediate nodes. Thus, the code dissemination that needs to be sent to the border sensor nodes should be highly confidential. The confidentiality of this code dissemination cannot be compromised at any cost, hence Key management is also an important issue. A protocol is developed to securely send the code dissemination to the border sensor nodes via intermediate nodes. The Protocol is implemented using nesC on TinyOS platform and evaluated the performance.

Overheating of components and devices in electronic systems led to the application of mini and microchannel technologies. The aim is to eliminate as fast as possible the maximum heat quantity from these systems in order to ensure an increased reliability and functional stability. Analysis of a laminar flow through a mini-channel has been done by a numerical model method by considering the surface irregularities. The process has been carried out as three phases and comparison is made on the variation of temperature on different cross-section. The objective of the work is to investigate fluid flow and temperature variation of regular cross-section with that of irregular cross-section. The result for the channel with surface irregularities is compared with those of a smooth channel with regular cross section shape and geometry. From the investigation, we obtain that the actual prediction of flow and heat transfer characteristics of channels of small cross-section requires the considerations of surface irregularities while performing the numerical computations.

A zero day attack is the type of attack where people make use of flaw in the software developed by various companies. There is no patch available so it is difficult to tackle such types of attacks even when developers of the company are known to this. For any network such attacks can be possible only way to get through this is to prevent such types of attack. If the network administrator knows that how many such attacks can be possible then he can make some changes in his administrator rights. It is found that more than five thousands vulnerabilities are occurring per day. We are proposing complete novel scenario which can lead to the counting of such vulnerability in very efficient way. Using this method we can easily provide option of network hardening so as to prevent it from unknown vulnerability.

The Shielded Metal Arc Welding (SMAW) is the most widely used welding process in the small scale industries, because of its low cost, flexibility, portability and versatility. The SMAW welding parameters are the most important factors affecting the quality, productivity and cost of welding. The objective of this study is to develop the parameters for Shielded Metal Arc Welding (SMAW) to provide continuous and leak proof joints in 48mm diameter steel pipe with 3mm thickness during the process. The selected important welding parameter like welding current, welding speed, root gap and position of electrode based on field expert suggestion available literature and on scientific reasons. On the selected parameter sufficient number of trail runs is conducted as per Taguchi method because experimental optimization of any welding process is often very costly and time consuming. For each factor optimum range is fixed, further the range is split into 5 levels. So that the experiment have become 4 parameters (factors) each with 5 levels. Based on this, L31 (54) Orthogonal Array (OA) is selected. Experiments are conducted according to OA and results are obtained. The leak proof joints can be identified by these results under few specific operating conditions. Under these condition effect of noise are nullified and the contribution of each parameter towards the leak is also estimated by ANOVA.

Dental biometrics has emerged as vital biometric information of human being due to its stability, invariant nature and uniqueness. Dental radiograph and dental photograph are tools mostly used in biometrics as it provides information about teeth in detail. The proposed system has four main stages as preprocessing, feature extraction, feature matching and finalized recognized person. Preprocessing stage uses conversion and segmentation of quiery input image to make it fesible for feature extraction. Feature extraction uses SIFT algoritham as it extract highly distinctive invariant features which uses for matching purpose. In matching input image is comparatively matched with every image of database and find out the maximum matched features image of person. The system is work for both types of dental images i.e. photograph and radiograph in which two different datasets are required. The required database contains 50 images of dental photographs and 50 images of dental radiographs so experimentation has done on total 100 images and that are taken from Dyanita dental clinic. The proposed system is implemented in Matlab/ R2012a programming tool.

This paper is about transmitting electricity wirelessly using high voltage high frequency signals. The device uses concepts of tesla coil, mutual induction and resonance to procreate electricity in the receiver coil placed at a distance. The main aim in designing this device is to allow automatic recharge of mobiles when the power gets drained. This is device can also be used for internal pacemaker charging without the need of surgery. To achieve this, mutual induction and resonance concepts were employed Mutual induction is achieved through high voltage pulses that can be achieved as a novel attempt. From this experimental setup the maximum distance of transmission achieved is 55cm.

Computerized media content security has progressively turned into an imperative issue. Since video watermarking is a major technology used in copyright protection, a key prerequisite for it is the advancement of the imperceptibility and robustness. We propose a hybrid watermarking scheme for digital videos based on singular value decomposition (SVD) and multilevel Discrete Wavelet Transform (DWT). The two key aspects of watermarking schemes are copyright protection and robustness. In this, we are embedded the watermark in the video frames in two forms using SVD portioning of the watermark, the video frames are portioned into layers (RGB) and DWT sub-band decomposition of host video, for providing copyright protection as well as reliability. Since Scaling factor is an image dependent so we are providing it in the form of a matrix. First level embedding of the singular values is used for substitution of the singular values of the selected video frame layer providing efficient robustness and fidelity of the scheme. The second embedding is used hiding the U and V matrix from SVD of the watermark are converted to binary form and then embedded into the lowest energy band of the DWT transform of the selected layer. Experimental results are provided to illustrate that the proposed scheme is able to withstand a variety of video processing attacks as well as imperceptibility, especially in geometrical attacks.

Chitosan (CS) based thin films fabricated by incorporated with plasticizer (glycerol) at different weight ratios were prepared. This was carried out by employing a solvent-casting method incorporating with Halloysite nanoclay (nanotube) and Silica nanoparticle (spherical) into the films. Scanning Electron Micrographs (SEM) showed that nanoparticles were dispersed homogeneously throughout the polymer matrix in all of the chitosan-nanocomposite films; tensile test (UTM) showed that the mechanical strength of the films varies with the nanoparticle concentration. It was observed from the Thermal Gravimetry Analysis (TGA) results that there is no significant variation in the thermal degradation temperature of the films with the addition of the nanoparticles. The hydrophobicity increased with the addition of nanoparticles, as seen from the contact angle, moisture content and water solubility result.
