Heat transfer enhancement techniques are used to augment heat transfer rate. Heat transfer enhancement techniques are most commonly used in areas such as radiators for space vehicles, thermal power plants, automobiles, refrigeration and air-conditioning equipment’s ,coolant (oil) cooling systems, , heating and cooling in evaporators, process industries, industrial heat recovery equipment’s, power sectors, electronic cooling aerospace, etc. These techniques broadly classified into three categories viz. passive techniques, active techniques, a combination of passive and active techniques i.e. called compound techniques. Passive techniques, where inserts are incorporated in the flow passage to enhance rate of heat transfer, are very advantageous as well as effective as compared with active techniques, because the insert manufacturing process is simple and these techniques can be easily employed in an existing heat exchanger. In design of compact heat exchangers, passive techniques of heat transfer augmentation can play an important role if a proper passive insert configuration can be selected according to the heat exchanger working condition (both flow and heat transfer conditions). In the past decade, various types of studies have been reported on the passive techniques of heat transfer augmentation. The present paper is a review on progress with the passive augmentation techniques in the recent past and will be useful to designers implementing passive augmentation techniques in heat exchange. The heat either may be used to add or reject from the system. There are many types of heat losses observed in these processes researchers are working hard to minimize these losses and enhance the heat transfer rate in either directions. This paper made an attempt to review the some of the passive techniques and revel the possibilities of the combined approach of this technique.

"Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers." Most of the people around the globe are not only familiar with Internet, but Internet has become one of the vital elements of survival for them. From school projects to work place, or connecting with loved ones to scheduling a day, everyone has become dependent on internet. The impact of internet is so deep and well-rooted that we have forgot to live without internet. In such a scenario, there are parts of the Globe that doesn’t receive internet facility, or even if they do, the access is limited due to weak signals or governmental restrictions. And the places, where accessible internet is provided, the facility charges a good amount of money. Since, no problem exists without a solution, we got ‘Outernet’.

This paper significantly contributes to address the problem of occupational injury prevention and control strategies through the investigation and application of epidemiological methods to underground mines. The epidemiological methods developed in this work will assist the safety management to identify significant risk factors and the risk groups which can provide a basis to develop prevention strategies including training. The findings of the multivariate statistical analyses indicate that both the personal and impersonal factors affect the occurrence of an injury. In this study although 12 risk factors were suspected, the epidemiological analysis suggested that only 5 factors are statistically significant. These are age, perception of working condition, emotional stability, job stress and safety performance. The structural equation modeling results revealed that personality (emotional stability and impulsiveness), maturity (age and experience), and job characteristic (perception of working condition, safety environment, and management and supervision) were significant predictors of occupational injury. The analyses indicated that the variables describing personality and job characteristic had also indirect and negative effect on occupational injury via job stress, job satisfaction, job involvement and safety performance. Specifically, the management should pay due attention towards the problems of working environment and safety of the workers. Moreover, workers should be trained to develop the positive psychological traits to maintain the balance between rigidity and flexibility which is helpful in injury prevention. Workers with negative traits like emotionally instable and older workers should be employed in less hazardous job. The occupational injury research community cannot effectively evaluate and implement prevention strategies on its own; neither can industries, nor employers, nor workers at risk. They all have to do it together in partnership.

There are many approximate pattern matching algorithms proposed in the literature. They mainly focus on solving the k mismatch problem which find all occurrences of a short pattern in a long text string with at most k mismatches. But these mismatches can be anywhere in the pattern. In many cases it is essential to find the approximate pattern varying only in specified locations. Finding Transcription Factor Binding Site along the DNA is an application of such type of fuzzy pattern matching. Transcription factors (TFs) are proteins that bind to the DNA molecule to control the expression of their target genes. TFs have a DNA-binding domain that recognizes a short specific DNA sequence called transcription factor binding site (TFBS) and bind to DNA. Every transcription factor is able to bind not only to a single DNA sequence but to a variety of DNA sequences that share a core structure. Binding motif for a TF is an approximate pattern in which variation can occur at specific positions in the pattern. The paper proposes an approximate pattern matching algorithm that allows position specific variation in the pattern. The algorithm can be used to locate the potential Transcription Factor Binding Sites along the DNA

In image Steganography the information is hidden exclusively in images. Steganography is the art and science of secret communication. It is the practice of encoding/embedding secret information in a manner such that the existence of the information is invisible. Steganalysis is the breaking of Steganography and is the science of detecting hidden information. The main objective of steganalysis is to break Steganography and the detection of stego image. Almost all steganalysis algorithms depend on Steganography algorithms introducing statistical differences between cover and stego image. Similar techniques can also realize large-capacity embedding for Steganography. Candidate transforms include discrete cosine Transform (DCT), discrete wavelet transform (DWT), and discrete Fourier transform (DFT). By being embedded in the transform domain, the hidden data resides in more robust areas, spread across the entire image, and provides better resistance against signal processing. The Work is carried out with the objectives to find out the best image Steganography method among the Discrete Cosine Transform, Discrete Wavelet Transform, Hybrid Transform and Novel Transform method with application of bilateral smoothing for denoising purpose on the basis of its factors like Peak Signal to Noise Ratio, Mean Square Error, Normalized Absolute Error and Correlation .The primary objective of my current work is to increase PSNR and decrease MSE and NAE of the image.

The level set method which is a numerical technique for tracking interfaces and shapes. Sometimes image is affected by noise and so on. So a level set method (LSM) was used to segment the images, which can decrease the inflection of the noise and reduce the computation time. But the problem lies in its re-initialization task. Hence the proposed level set method with diffusion is implemented with two step splitting method (TSSM) is derived which is free of re-initialization process. Also the level set method could not perform well for the images highly affected by noise and high dimensional images by optimizing the computation time and number of iterations to get the exact contour.

clustering is “the process of organizing objects into groups whose members are similar in some way”. A cluster is therefore a collection of objects which are coherent internally, but clearly dissimilar to the objects belonging to other clusters.Document clustering is used in many fields such as data mining and information retrieval.to compare the clustering results of K-Mean approach ,agglomerative approach , partitioned approach for each of the criterion functionsusing real-world documents, and to establish theright clustering algorithm to produce high quality clustering ofreal-world document. The goal of a document clustering method is to reduce intra-cluster distances between documents, while exploiting inter-cluster distances (using an appropriate distance measure between documents). A distance measure (or, dually, similarity measure) thus lies at the heart of document clustering. The large variety of documents makes it almost unfeasible to create a general algorithm which can work best in case of all kinds of datasets.
