This study is focused on assessment of digital library (DL) contribution on learning and teaching process for students and teachers of information science department. The researcher has selected 94 (41.2%) respondents from information science department through random sampling technique from the total population of 228. The data was collected using interview and questionnaire methods; and interpreted through quantitative research methods. Descriptive statistics was employed and analyzed the data that has been collected. The result of the study shows that most of the respondents use digital library which is available through internet to improve learning and teaching process. The study recommended that the ways of digitizing the digital library. The researcher concluded that the digitization of DL is not well equipped and satisfactory. Finally the researcher recommends the concerned bodies may participate in the digitization process to improve learning and teaching process.

All trades of village artisanship in blacksmith carpentry, stone etc. contributed to the design of development of farm tools through artisan's ingenuity. Carpentry made the counterpoise to lift the water from wells to irrigate crops. Big size of earthenware was made by potters to store grains for month to be safe from insects and pest's cobblers used whole skins of animals to carry water to irrigate horticultural crops besides entering dust roads. Farming is the backbone of Indian economy. In this agriculture sector there is a lot of field work, such as weeding, reaping, sowing etc. Apart from these operations, spraying is also an important operation to be performed by the farmer to protect the cultivated crops from insects, pests, funguses and diseases for which various insecticides, pesticides, fungicides and nutrients are sprayed on crops for protection. As agriculture was the mainstay of the population, farmer required hand tools to do work, improve labor productivity and quality of work, therefore the results in poor productivity and obtain low yield MAE(Multipurpose Agriculture Equipment) was developed. We have developed agriculture needs to find new ways to improve efficiency. One approach is to utilize available information technologies in the form of more intelligent machines to reduce and target energy inputs in more effective ways than in the past. The advent of new concept gives the opportunity to develop a complete new range of agricultural equipment based on small smart machines that can do the right thing, in the right place, at the right time in the right way. Keywords-MAE(Multipurpose Agriculture Equipment) I. INTRODUCTION Farming has undergone a great evolution in last 50 years. Out of the various reasons involved for this evolution is control of various diseases on crops. During initial days there was only hand spraying people use to do. Then slowly there has been development of various methods to spray out chemicals and dusts. Though these devices were highly efficient, there is a need to have certain changes. Chemicals are widely used for controlling disease, insects and weeds in the crops. They are able to save a crop from pest attack only when applied in time. They need to be applied on plants and soil in the form of spray, dust or mist. The chemicals are costly; therefore equipment for uniform and effective application is essential. Dusters and sprayers are generally used for applying chemical. The application of pesticide is one of the most frequently used methods to protect crops and trees against diseases and insects in agriculture. In the modern agriculture, the usage of pesticides is still increasing, moreover the 90% of these pesticides are being applied in the form of liquid spray and mostly by using the pressure gained from direct energy sources like electrical energy and chemical energy. Increasing public concern about the potential damage of chemical and electrical inputs in agricultural spraying systems has challenged industry to develop new and effective methods of spraying which will maintain environment friendly approach. II. DIFFERENT OPERATIONS A. Sowing and Fertilizer It is used for line sowing and fertilizing of cereals and other crops. It is a low cost line-sowing device in which seed metering is done manually by the operator by dropping the seeds in the funnel provided for the purpose.

Abstract— Improving the security of applications is one of the crucial points required to assure the personal information .This paper presents a biometric authentication procedure consisting of verifying the identity of valid users by making a signature in the air while holding the mobile phone. The verification of the identity will open up the application of steganography which consist of image on which various processing techniques can be applied. This model is based on messy watermarking scheme for the authentication of images.First it separates RGB colors of a pixel of image, dynamically generates the watermark using messy models by applying Chaos algorithm and it is embedded inside the image by expanding intra plane difference between any two color planes of images known as intra plane difference expanding. All the above process comes under primary watermarking. Then alpha channel embedding algorithm is used in next step for secondary watermarking. The final image generated is sent over a network and this Authentication guesses whether that received image has been modified or not and detect the tempered regions.
