 Abstract

The phase transition temperatures and phases in ferroelectric series of 2-(4- n alkanoyloxy benzylidenamino) benzothiazoles ( where n=12 and 16 ) are studied using polarizing micro scope (POM) and it reveals the occurrence of SmA phase. Dielectric parameter studied as a function of temperature can be used to determine the phase transitions temperature in LCs. The phase transitions are in good agreement with the dielectric studies data.

 Abstract

This article deals with the double diode MATLAB modelling of a photovoltaic module. In this paper, double diode model was developed using the fundamental equations. To validate the simulink/ MATLAB model., developed model results are compared with the experimental data sheet. The developed double diode model is operated at the different operating conditions i.e. at the irradiances 1000W/m2 and 800 W/m2; the temperatures 250 C and 200 C. The required resistances are extracted by using the newton-rapshon method. The simulated results are perfectly coinciding with the experimental values.

 Abstract

The dissemination of shock waves through any medium results in change in the property on fluids, this is because of the characteristics of the shock wave. This paper deals with shock wave interaction on fluids. The strength of the shock is determined by its mach number. Initially the experiment is carried in water sample taken from our institute location. The experiment is done by changing the number of shockwaves.From our initial experimental results we found that change in salinity content of the water . On Continuing this idea, we are trying to carry out experiments on shock treated water to find mineral changes.

 Abstract

Digital watermarking is a branch of information system security that finds tremendous applications in the modern era of internet and digital data exchange. Specifically, digital image watermarking finds vast applications in medical image processing, satellite images and related fields. In this paper, a blind and robust watermarking approach using DWT and SVD based transformations is presented. A given color image partitioned into RGB color planes and the entropy of each of the plane is computed for choosing the optimal plane for watermark embedding. The chosen plane is then segmented into non-overlapping blocks and watermarking bits are embedded into each of the blocks separately, considering the human visual system (HVS) characteristics based on the entropy values. For each of the block, the 2 level DWT is performed which transforms the image into four sub-bands namely HH, HL, LH and LL bands. Subsequently, Singular Value Decomposition (SVD) is performed on the HH band. The HH band is chosen to provide a robust watermarking as it contains most of the information contained in the original signal. Alternatively, LL band can be chosen to implement fragile watermarking scheme with a high PSNR values. To embed the watermark bits, the U and V matrix values are suitably modified to embed a zero or one. As compared to the S matrix of SVD transform, the embedding of the watermarking bits into the U and V singular matrices gives a much robust watermarking with low false positive rate and hence, are preferred when robustness is critical issue. The proposed technique is compared with those proposed by Nasrin M. et.al. and the simulation results established that better robustness and imperceptibility is achieved as indicated through PSNR.

 Abstract

In the time of new invention Networks many rising and future empower advancements achieve the prerequisites of pervasive correspondence systems. Remote Sensor Networks is a fundamental classification of these best in class advances, the gigantic worries of these systems are vitality proficient and efficient information accumulation. Bunch based directing in WSNs is a colossal answer for upgrade the vitality productivity of the hubs and creative information gathering. Many examinations on organize lifetime and information accumulation have been proposed by the (LEACH) Low Energy Adaptive Clustering Hierarchy conspire that permits the part of the group head turned among the sensor hubs and endeavors to disseminate the vitality utilization through every one of the hubs. The lifetime of WSNs will be influenced by the Cluster Head choice; this is on the grounds that a CH expends more power than a Cluster (non-CH) hub. In this examination think about, a vitality effective bunch head choice in Mobile WSN is proposed, investigated and approved on the premise of remaining vitality and randomized determination of the hub, which is not doled out as a group head in past round. Additionally, the proposed approach demonstrates the noteworthy changes when contrasted and LEACH and A Novel Application Specific Network Protocol for Wireless Sensor Networks conventions regarding vitality utilization of sensor hubs, improved system lifetime and proficient information assembling because of less vitality utilization amid information transmission.
