In this paper a generalized closed form expression for the average detection probability of an energy detector is derived in terms of computable Meijer G-function. Where the reporting channel in the centralized cooperative spectrum sensing is experiencing a n - μ fading. The reporting network is modeled as secondary users and fusion center equipped with multiple antenna for reporting. The fusion center combines the received data using maximal ratio combining and performs energy detection to make decision. The arrived generalized low complex expression offers the different fading conditions of reporting channel. Also, it is generalized for multiple antenna scenario. The arrived expression is validated by analytical results over different n - μ values with various multiple antenna scenario.

In this paper, an effective algorithm for providing copyright protection is proposed by using a new embedding strategy for Discrete Wavelet Transform-based video watermarking. Discrete Wavelet Transform (DWT) is applied on the video, to convert the spatial data into frequency domain, having low pass and high pass components. The low frequency component is used for generating the key, by using the watermark image and the binarized Low frequency part (LL) of the video frame. Same procedure is applied on each frame to generate the key for corresponding frame. This generated key should be used at receiver for extracting the watermark which provides copyright protection. Blind watermarking technique is used in this paper which require only key to extract the embedded watermark. The original video is not required during extraction. To criticize the robustness of algorithm, the original watermark image is compared with extracted watermark image after several attacks and their Peak Signal to Noise Ratio (PSNR), Normalized Correlation Coefficient (NC) and Structural Similarity index (SSIM) are calculated. The experimental results demonstrate that the watermark is invisible and it is robust against the various attacks and addition of noise to the video.

Establishing an underwater wireless acoustic communication link for practical applications is still a difficult task because of the severe channel conditions. Doppler and range spread are extremely high for under water channels (UWC) compared to ordinary radio channels. Moreover, the ever varying nature of the UWC increases the uncertainty in predicting the worst case values of doppler spread and range spread. In recent years, orthogonal frequency division multiplexing (OFDM) has emerged as the single solution to most of the problems in wireless communication systems. OFDM has dominated over single carrier modulation techniques mainly because of the simple, robust and low complexity receiver design with high data rate and high band width efficiency. But, it is only very recently that people have started exploring the usage of OFDM for UWC. In this paper, the design, modeling and testing of coded OFDM based underwater acoustic communication system for high data rate applications is explained.

SOX4; a crucial human protein acts as a transcriptional regulator for accurately determining the cytological regulations in human beginning from the embryonic development. It thus is aided by its only binding protein partner; human syntenin who binds to the C-terminal domain of SOX4 protein. Wet laboratory documentation well documents the interaction of proteins on this regard but the residual level analysis via optimization and simulation operation remains yet undisclosed. So, for the purpose, the essential responsible domain sequence of SOX4 protein was extracted thus the protein was modeled via the satisfaction of its several stereo-chemical properties. The human syntenin protein structure was there-after extracted from its experimentally validated crystal structure. Docking simulations of the two proteins further formed the essential protein complex, which then underwent necessary optimization and molecular dynamics simulation. Residual involvement from the pre optimized and post simulated protein-protein complex was evaluated and compared individually, with a focus on the pattern of binding. The doubling up of the predominant ionic interactions and side chain-side chain interactions poses the final simulated complex to be greatly interactive one. Mainly, polar positively charged; His14 from syntenin and Ser8 from the C-terminal protein domain of SOX4 protein aided in the stronger interactions, with His14 forming three predominant interactions solely. Furthermore, Asp10 from syntenin and Glu11 from SOX4 C-terminal domain also remained for increasing the strength of the duo protein complex. Statistically significant evaluations from free energy of folding, net area available for solvent accessibility along-with the conformational shifts from coils to β-sheets in the protein complex additionally affirms the simulated complex structure to increase its stability and conformational strength post optimization and simulation. Therefore, this current molecular level optimized exploration provides a novel scope to scrutinize the residual interactive pattern and the most stable interactive protein structure dependable for the proper cytological regulation in humans. For the upcoming research, it thereby instigates the clinical and biomedical field for cell fate determinations and neurogeny.

Digital Micro fluidic based Biochips (DMFBs) in current years have provided an efficient alternative platform in the field of bio-chemical analysis, particularly for inexpensive, convenient, and not reusable devices mainly designed for medical diagnostic applications. For a major class of DMFBs droplet actuation is depend on the rule of electrowetting-on-dielectric, where separate droplets of nano liter volume can be manipulated using 2D array of electrodes. Most important design automation issues in DMFBs is the concurrent routing of droplets inside a 2D array. The reason of droplet steering is needed to plan the movement of a number of droplets in a time synchronized mode within a 2D array while minimizing resource consumption and within optimum latest arrival time. The droplets may be classified as homogeneous or heterogeneous. In case of heterogeneous droplet routing, major issue is the avoidance of cross contamination where as for homogeneous droplet routing sharing of electrodes among different route paths for minimum resource utilization remains the main focus. In our paper, we put forward an algorithm for routing of heterogeneous droplet inDMFBs. We further developed a routing simulator that graphically displays detailed route performance for heterogeneous droplets within a predefined DMFB layout. We have used benchmark suite I and III to analysis our algorithm.

Solar energy has gained momentum in the past few years with the current focus being on developing solar cells and panels that can be used on a large scale. A large part of the challenge lies in maintaining acceptable levels of efficiency while increasing scale. In this paper, we present a dual tracking methodology to increase the efficiency of existing photovoltaic systems. Our model employs a solar tracking scheme coupled with maximum power point tracking to achieve better efficiency. Solar tracking is used to ensure that the maximum permissible sunlight falls on the panel at any given point in time, while maximum power point tracking ensures load matching. The results are based on simulations performed in MATLAB.

An area efficient temperature sensor using Ring Oscillator (RO) is proposed. It is basically implemented with two ROs, one being temperature-sensitive and the other temperature-insensitive. Temperature measurement is done in two steps. Initially, temperature-to-time conversion is performed when temperature-sensitive RO is enabled and then time-to-digital conversion is performed when temperature-insensitive RO is enabled. This two step process optimizes the area because only one counter is sufficient. The feedback provision enables only one RO at once, providing low dynamic power dissipation. A True Single-Phase Clock (TSPC) based high speed counter is employed to meet the requirement. It is designed using UMC 0.18 μm CMOS technology with the supply votage of 1.8 V and the simulation results are presented. The proposed sensor is capable of measuring the temperatures from -55° C to 125° C with the resolution of 5.68 LSB/°C. It dissipates 650 μW with the conversion rate of 300K Samples/S and occupying 10.05 μm2.
