Abstract

In research community there are statements that NT is still not well defined (Kumar, 1999, October 21), some defines it on the basis of physical dimension of structures ranging from 0.1 nm to 100 nm; it means different for different disciplines of people.

Abstract

IEEE defines requirement as [1] “(1) a condition or capability needed by a user to solve a problem or achieve an objective. (2) A condition or capability that must be met or possessed by a system to satisfy a contract, standard or other formally imposed document.” SRS describes what the proposed software should do without describing how the software will do it. A basic limitation for SRS is that the user needs keep changing as the environment in which the system is to function changes with time. SRS is the medium through which the client and user needs are accurately specified to the developer.

Abstract

Internet has an important role in information sharing and transmission of message so encryption is very much essential for the transmission of secure data over the wireless communication network. While the data is transmitted the main focus is on the encryption techniques for secure data transmission. Many encryption techniques are used for security of data over the network. Cryptography has come up with many encryption techniques such as encryption algorithms. In this paper, two encryption algorithms Advanced Encryption Standard (AES) and Data Encryption Standard (DES) are implemented using MATLAB software.

Abstract

Privacy preserving becomes an important issue in the development progress of data mining techniques. Privacy preserving data mining has become increasingly popular because it allows sharing of privacy-sensitive data for analysis purposes. As we know that, there has been an important research area that how to protect private information or sensitive knowledge from leaking in the mining process. Our goal in investigating privacy preservation issues was to take a systemic view of architectural requirements and design principles. This paper describes meaning of data mining, Privacy, Design architecture for privacy preserving, types of privacy preserving, privacy preserving data mining, data distortion, data encryption, and reconstruction techniques in detail.

Abstract

An important aspect of the physics of real materials is the nature of their magnetic properties. The magnetism is an ancient subject which still continues to fascinate us. The frustrated quantum antiferromagnets form an exciting research area of current interest. On one hand, the advancements in material chemistry have made it possible to synthesize interesting new materials; on the other, theoretical studies of frustrated spin models provide better insight into the nature of complex quantum states of spin systems . Ever since the discovery of the high-TC superconductivity in cuprates, the question of unconventional mechanism of superconductivity and the studies of spin-liquid quantum phases, have been treated with related interests. This makes the studies of frustrated spin systems, together with the search for new mechanisms of superconductivity, a topic of great current physical interest. The discoveries of new materials make these studies equally more desirable and exciting.

Abstract

Any one of a large group of nitrogenous compounds. Purines are produced as end products inthe digestion of certain proteins in the diet, but some are synthesized in the body. Purines arealso present in many medications and other substances, including caffeine, theophylline, andvarious diuretics, muscle relaxants, and myocardial stimulants. Hyperuricemia may develop insome people as a result of an inability to metabolize and excrete purines. A low-purine diet or apurine- ree diet may be required. Foods that are high in purines include anchovies and sardines;sweetbreads, liver, kidneys, and other organ meats; legumes; and poultry. The foods lowest inpurine content include eggs, fruit, cheese, nuts, sugar, gelatin, and vegetables other thanlegumes.
