Review On Grid Wireless Sensor Energy Reduction Approaches
Sensor nodes have limited battery power with limited lifetime, then ultimately increase the survival time of network. During data sensing the battery of sensor nodes cannot be change in the sensor network areasReduce the energy consumption of nodes by finding the centrality of nodes then find the high centrality of nodes as a cluster head. Balance the energy and distance by bacterial for optimization method

Review on checkpoint optimization in WSN
A shared heterogeneous computing is comprised in distributed system & data resources are distributed across the network boundaries. Owing to geographically distributed resources, which is heterogeneous in nature, owned by different individuals or organizational that owns policies with varying loads & the Resource Management system caused by the availability, even obtaining the QOS in the resource faults existence a comple which overhead of checkpoint by clustering based checkpoint and optimize the number of nodes in cluster by Flower pollination algorithm and use centrality base trust case depend on connectivity and importance of node using game theory approaches.

Investigation of Phenol Adsorption Characteristics by Chemically Treated Ganga Soil
In this study, chemically modified natural clay was employed to remove phenol from its aqueous solution. The effects of various parameters on phenol adsorption were investigated through batch adsorption in order to find out the phenol adsorption characteristics onto the surface of modified adsorbent. The adsorption of phenol was found to increase at lower solution pH and comparatively lower temperature. The adsorption was also found to increase with increase in initial concentration and contact time but decrease in adsorbent dose. The maximum adsorption capacity of 87.08 mg/g was found at a solution pH of 3, initial concentration of 100 mg/L, adsorbent dose of 1 g/L and temperature of 30 °C. The adsorption capacity was found to increase with decreasing temperature indicating exothermic nature of the adsorption process. The Adsorption characteristics was correlated by Langmuir, Freundlich and Tempkin isotherms at three different temperature and Langmuir isotherm exhibited a better fit to the experimental data. The kinetics of the adsorption process was also studied by using pseudo first-order, pseudo second-order, intra-particle and Elovich model at three different temperatures and concentrations. It was found that pseudo second-order kinetic was well correlated with the given experimental data. The thermodynamic study of phenol adsorption also confirmed the exothermic nature of the adsorption process.

Efficient Timing Closure in SOC through Timing Quality Checks and Engineering Change Order
Ensuring correct operation of design despite rising levels of design complexity has been a major focus of research and development since the dawn of digital system design. As design size and complexity increase, so is the need to verify designs quickly and reliably. This, combined with the reduced design cycle of 3-6 months, makes verification an extremely challenging task. Once the chip is taped out, if the chip is not meeting timing or if the chip is consuming too much power then it is a big issue and results in huge loss. So in order to avoid these post silicon surprises, preliminary signoff checks are must. This paper covers the various kinds of timing quality checks that are used in the industry including the checks related to connectivity, clock, Max slope and Max capacitance, checks for Latch etc. Also in advanced technology nodes one has to consider the effect of PVT variation, temperature inversion, noise effect on delay, which is adding more scenarios for STA to cover. With big SOC project, one timing ECO run normally takes 3~5 days. The turn-around-time for timing ECO and timing signoff has become a bottle neck in the later stage of the project. So there is an immense need of effective implementation of ECO with new technologies including physically aware ECO with less resource, reduced design cycle time and reduced manual effort. The proposed algorithm is tested on multiple industrial design and found to achieve good improvement interms of Worst Negative Slack, Total Negative Slack and Failing End Points. Also the algorithm is physically aware meaning that the placement blockages, congestions are considered while inserting buffers. The algorithm works under Distributed Multi Scenarios Analysis (DMSA) environment and considers the effect of ECO across multiple corners and modes.

High Security Data Hiding in Videos Using Multi-Frame, Image Cropping and LSB Algorithm
An art of invisible communication by embedding secret information in other sources like text, image, audio, and video is called steganography. A high security data hiding technique is proposed in this paper. Selected frames from the video are cropped into four equal parts, block of secret data is hiding in each three channels of crop of a frame using LSB technique in a predefined sequence, and then image crops are joined to get stego image/ frame. This stego frame is replaced in video in its original position. Comparative study is performed between proposed approach and existing approach using different metrics such as visualization test, MSE, PSNR and CPU time. Experimental results shows that the proposed approach is more secure compared to the existing approach.

Recognition of Online Handwritten Characters Using Lipi Toolkit
Handwritting deformation and complex structure has been one of the most challenging problems in handwritten recognition. In this paper a online handwritten recognition tool has been for recognition. Online handwriting data is collected as strokes, where a stroke is defined as the sequence of data points captured from the event of a pen-down to the subsequent pen-lift. Lipi toolkit engine is used to develop the character recognition system. Lipi toolkit is open source engine. Engine uses backpropagation and nearest neighbour for pattern classification and recognition which employs unsupervised learning algorithms. It has shown that the Lipi engine is feasible for online handwritten English character recognition to a certain degree.
