Design of efficient compression and cryptographic model for an image transmission using WBCT and ECC
There is always a need for more memory and enhanced security for transmission. Image compression has gained importance because it reduces the storage space with the only acceptable amount of degrading in quality. Also, cryptographic techniques are used to provide security during transmission. In this project, an efficient compression and cryptographic model for image transmission are proposed. An input image of any format is converted to a grayscale image and Wavelet-Based Contourlet Transform(WBCT) is applied. Wavelets have the capability of approximation of images with sharp discontinuities, but they are not efficient for the approximation of images with a smooth contour. Contourlet transform uses Laplacian pyramidal decomposition and a directional filter bank to produce effective and powerful multiresolution and directional decomposition of an image. Together Wavelets and Contourlet Transform makes an image suitable for image compression. Huffman coding is used for lossless compression of data(image). This compressed image is encrypted using ECC (Elliptic Curve Cryptography). ECC has its own advantages such as smaller keys with enhanced security, requires less computing power, battery life, and memory. The ECC decryption algorithm will perfectly recover the original image. The work is implemented by using MATLAB. The compression ratio is 4.2 to 5 and PSNR value in the range of 24-32.

Reduction of low pressure steam consumption in deaerator of coal fired boiler
ITC PSPD (Bhadrachalam) is one of the biggest and renowned paperboard manufacturers in India. The unit has integrated pulp mill and 7 no’s paper and board manufacturing machines powered by its own thermal power plant of installed capacity of 140 MW with a network of 6 turbines and a battery of 9 boilers, which include 3 no’s Soda recovery boilers and 5 no’s Atmospheric Fluidized bed combustion (AFBC) type and 1 no Circulating Fluidized bed combustion (CFBC) type coal-fired boilers. AFBC and CFBC boilers generate high-pressure steam with 62 ata, 102 ata and temperature 480 degrees C, 525 degrees C respectively. One of the AFBC Boiler of capacity 90 TPH consumes Low-pressure steam 0.150 Tons per Tons of High-pressure steam (Specific LP Steam) which is very high. This can leads to an increase in the cost of HP steam generation. Higher specific low-pressure steam consumption in boilers is a serious concern for the organization because of the low-pressure steam cost is nearly Rs 750/ton The reason for High LP steam consumption is Low Feed Water temperature which is coming to Deaerator. So we would like to increase the temperature of DM water by recovering heat from a process which is venting to atmosphere

Self-help group and empowerment of women- A case of Haveri district of Karnataka
Self Help Groups (SHGs) Women’s self-help groups (WSHGs) in particular, represented a form of intervention that is a radical departure from most current programmes. They are an effective strategy for poverty alleviation, human development, and social empowerment. Poverty represents a negative facet of human development. The state of Karnataka has always recognized the need for, and value of financial services to the poor. Yet there is no reason to believe that the basic reasons why people need money. The poor borrow money to life events like births, deaths, wedding etc. And to meet emergency needs related to the accidents drought and illness and for others unforeseen contingencies.

Market basket analysis using association rule
The proposed paper focuses on the basic concepts of association rule mining and the market basket analysis of different items. In the current study, the market analysis would be done by collecting the real, primary data directly from retailers and wholesalers. The efficiency of the FP- Growth algorithm can be measured in terms of mining of the frequent pattern. Precisely, we apply the FP-Growth algorithm on the various data collected from different stores in order to trace the various association rules comprising of a basket. One discrete advantage is that it avoids the generation of candidate sets, which is computationally exhaustive. The results and conclusions drawn can be used in optimizing the market. This will help in predicting future trends and behaviors, allowing businesses to make knowledge-driven decisions.

A cram on mobile AD-HOC networks
Networks are used to communicate between two or more device. Networks are of two types one is wired network and another is a wireless network. In the computer world, the wireless networks become more powerful. MANET is a wireless network which is a collection of different separate devices which is used to communicate with each other devices directly. Ad-hoc networks are mostly local area network where the computers or any other devices that are used to share the data or any other information directly to one another without the use of centralized access point. MANET is an infrastructure less network. MANET is a suburbanized communication. Each and every devices or computer act as a server and client. In this paper, a survey of a mobile ad-hoc network is presented.

A pre experimental study to assess the effectiveness of computer assisted teaching on knowledge and attitude of parents on the influence of mobile gadgets and internet use on the development of their children
In today’s society, electronic media are thoroughly integrated into the fabric of life, with television, movies, videos, music, video games, and computers, central to both work and play. While these media outlets can provide education and entertainment to children, many pieces of research are concerned with the negative impact of electronic media on children. Media is used as a third parent or servant. A lot of aspects is important related to media exposure and child behaviour. Media exposure affects the neurodevelopment, nutrition and health and academic achievements of the child. Parent education plays an important role in the behaviour modification of the children. Magnitude of the problem --World scenario. According to the Common Sense media research Study,(2013), 1,463 parents were surveyed of 8-year-olds from May 20 to June 12, 2013 Half (50%) of all children ages 0 to 8 have used mobile apps, up from just 16% in 2011. Use of mobile media starts young: more than a third (38%) of all children under 2 have now used a mobile device for any media activity compared to 10% two years ago; among 2- to 4-year-olds, the rate has gone from 39% to 80%; and among 5- to 8-year-olds it has gone from 52% to 83%. This magnitude of the usage of the mobile gadgets daily by the children for hours together lead to many problems. This mobile gadgets usage by children are allowed by the parents to their children for their own good reasons who are Purposive cluster sampling technique was used to select the setting of the study. Unaware that this practice can lead to many health issues in the growing children. Therefore this study aims to study the effectiveness of computer-assisted teaching on knowledge and attitude of parents on the influence of mobile gadgets and internet use on the development of their children".20 parents of the children aged 6-12 years were selected from urban area of Delhi by Purposive cluster sampling technique was used to select the setting of the study. . Research design adopted was Pre experimental one group pre-test post-test only design for the present study. Instruments used for data collection. A self-administered structured Questionnaire, to collect demographic data and knowledge and An attitude scale regarding the effect of mobile gadgets on children aged 6 to12 years. The results show that shows the pre-test and post-test level of knowledge score among parents on the influence of mobile gadgets and the internet on the development of children. In the pre-test, 70% of them are having inadequate knowledge, 30% of them are having a moderate level of knowledge and none of them are having an adequate level of knowledge. In post-test, none of them are having inadequate knowledge, 40% of them are having the moderate level of knowledge and 60% of the parents have an adequate level of knowledge. In the pre-test, 55% of them are having Poor attitude, 30% of them are having a moderate level of attitude and none of them are having a good level of attitude. In post-test, none of them are having Poor attitude, 35% of them are having a moderate level of attitude and 65% of them are having a good level of attitude. Knowledge and attitude of the parents were positively correlated at p= 0.001 level in the post-test which proves that the computer-assisted teaching was very effective in the improvement of knowledge and attitude of the parents regarding the effects of the mobile gadgets on the children aged 6-12 years.
