Authentication of Certificate in E-Learning Using Secret Key Digital Watermarking
Abstract:
In an e-learning system, while the documents are transmitting between the communicating parties, authentication is too much necessary. Digital watermarking along with the encryption technique may be used to provide authenticity. International Data Encryption Algorithm (IDEA) is one of the very useful symmetric key cryptographic algorithms, which is also free to all for any users, can be used for the key selection for encryption and 3DES can be used for watermark key selection. Digital watermarking is one of the very popular authentication techniques. So, while transmittingany document like registration certificate in any e-learning system, which should be transmitted from the developer to learner, the developer can use this technique to make a secure transaction. As we know that certificate is very essential document for any kind of learning, if the hacker can reach the document while transmitting from developer to learner, he can modify or destroy the documents. If the  developer uses our proposed technique while transmitting, and if the hacker makes any changes, then it affects the watermark, and easily identified. In this situation, student can also ask for retransmitting the certificate

Title:
Information and Communication Technology (ICT) for Sericulture Knowledge Management: Case of Indian Sericulture
Abstract:
In India, sericulture is not only a tradition but also a living culture. It is a farm-based, labour intensiveand commercially attractive economic activity falling under the cottage and small-scale sector. It particularly suits rural-based farmers, entrepreneurs and artisans as it requires low investment but with potential for relatively higher returns. Though the sector has registered an impressive growth during the last few decades, however, a number of factors have limited sericulture from achieving its true potential. Those factors may include insufficient capital and investment incentives, low level of technology dissemination, poor extension support, inadequate farm infrastructure, limited market and stagnant prices of sericultural products etc. In this paper,an attempt has been made to understand the importance of ICT in knowledge management particularly concentrating the case of Indian sericulture. Finally, an integrated model linking ICT with entire production chain of sericulture is suggested to establish close linkage between forward and backward sub-systems for greater efficiency and synergy

Insight into the Community Science and its Interaction with Information Science and Technology: A Socio-Techno Perspective
Abstract:
Community is nothing but the group of people having common identity. It is a fact that, in-general community refers to group of people or human being residing in a specific place. In the community sharing of ideology, thought etc play a lead role. It is a fact that the progress of technology and engineering has created a new type of community. These are—virtual community or online community. In simple terms, community may be deemed as an organism inhabiting a common environment in addition to interact with one another. Community development is the mechanism, concept and way to plan and modernize for complete development. Societal communication, organizational communications are also important for overall community expansion. Few aspects such as economic situation, awareness of political affairs, education and training etc are also important and most vital factors for community development as well as management. The Science and Technology which are closely related with the Community may be called as Community Science and Technology. However, the subjects of Applied Science and Engineering in concentration with community focus may also be treated as Community Science and Technology. This is a conceptual paper and it deals with several facets of Community Science and Technology including basics of community. The aim of this paper
is to higlight and explore the aspects of Community and some of the related and allied facets

Cognitive Radio, the Future of Wireless Communication: An Overview
Abstract:
Cognitive Radio (CR)has been drawing huge attention due to its capability to achieve spectrumoptimisation. Limited availability of spectrum and inefficiency in spectrum usage are guiding the wireless technology towards a new communication paradigm to exploit the existing wireless spectrum opportunistically. It enables sharing ofspectrum amongst a Primary User (PU) which is licensed user and a Secondary User (SU) which is not licensed user. Later is normally gypsy user. The Dynamic Spectrum Access (DSA) used by CR is a new technique which allows sharing of spectrum in such a manner that SUs can access the spectrum holes (voids or temporarily unused part of spectrum) in the licensed spectrum bands of PUs. This work is aimed at generatingtheinterest withinstudent community to undertake research in field of CR which is both challenging and extremely useful.

Introduction to Computational Fluid Dynamics
Abstract:
Computational fluid dynamics (CFD) is an essential tool, which usually uses numerical methods for developing approximations of the governing equations of fluid mechanics in the fluid region of interest.It sufficiently predicts fluid flow, heat transfer, mass transfer, chemical reactions, andrelated phenomena by solving the mathematical equations which govern these processes using numerical methods. Applying the fundamental laws of mechanics to a fluid, a set of coupled non linear partial differential equations is obtained. For most engineering problems these equations are solved analytically. Considering physical characteristics of fluid such as conservation of matter, momentum, and energy etc. throughout the region of interest of that fluid mathematical models are composed. In order to solve easily the simplifying assumptions are made for appropriate initial and boundary
conditions for the problem. To solve the fundamental equation of fluid dynamics, the Navier-Stokes equation and continuity equation, appropriate initial conditions and boundary conditions must be need to be applied. In spite of this, computational fluid dynamics can be used in the many areas of food processing industries for drying, sterilization, mixing, refrigeration etc. Drying is a common food manufacturing process.
