| Title | A Novel Steganography Scheme for RGB images with high image quality and Data hiding capacity |
| Authors | UMAMAHESWARI, MANOJ KUMAR, A.SHANMUGAM |
| Category | IT and Computing |
| Abstract | This paper presents a novel steganography scheme capable of concealing a piece of critical information in a host image that is a RGB image. The critical information is enciphered with the help of separate public key. This enciphered critical information is then embedded into the image blocks. A binary key matrix and a weight matrix are used as secret keys to protect the hidden information. Given a host image of size m x n, the proposed scheme can hide as many … |

| Title | A Simple Algorithm for Minimal Search Data Index: Active Partitioned Data Search Using PVM - Algorithm that battles with delay |
| Authors | N. Rajkumar, Dr.S.N. Sivanandam, |
| Category | IT and Computing |
| Abstract | In this paper, we examine the issue of mining association rules among items of a large database of search engines. The mining of association rules can be mapped into the problem of discovering large item sets where a large item set is a group of items which appear in a sufficient number of transactions. The problem of discovering large itemsets can be solved by constructing an index set of itemsets first and then, identifying, within the subdivided set. Generally this is done iteratively for each large Lk itemsets are equally partitioned into Sk subsets. To determine the related data of a searching text each index itemset contains the two candidate keys. One is moral text and another one is key that indicates the subset name where the data is originally located… |

| Title | Dynamic Data Fetch: An Efficient Algorithm for Query processing in large databases using Association Rules |
| Authors | N. Rajkumar, S.N. Sivanandam and M.R.Karthik |
| Category | IT and Computing |
| Abstract | Association rules are used extensively for data mining in many domains such as wholesale, retail marketing, lottery selection etc., and all the domains which is dealing with more number of data. Direction based large relationships are critical in many domains, including geographic information system (GIS) and image interpretation. They are also frequently used as selection conditions in large queries. In this paper, we explore the processing of large queries and propose and describe five basic data formulations to reduce the redundancy. … |

| Title | Efficient VLSI implementation of the block cipher Rijndael algorithm |
| Authors | Mrs.G.Umamaheswari, Dr.A.Shanmugam |
| Category | IT and Computing |
| Abstract | Cryptographic algorithms are more efficiently implemented in custom hardware than in software running on general-purpose processors. This paper addresses efficient hardware implementation approaches for the AES (Advanced Encryption Standard)Algorithm and describes the design and performance testing Rijndael algorithm. Compared to software implementation, hardware implementations provide more physical security as well as higher speed. An optimized coding for the implementation of Rijndael algorithm for 128 bytes has been developed. The speed factor of the algorithm implementation has been targeted and a software code in VHDL (VHSIC Hardware Description Language) … |

| Title | GLUTAMINE SYNTHETASE ACTIVITY AND FREE AMMONIA ACCUMULATION IN PEA (PISUM SATIVUM L.) ROOTS AND NODULES AS FUNCTION OF TEMPERATURE IMPACT |
| Authors | Anatolii K. Glyanko, Nina V. Mironova, Galina G. Vasilieva |
| Category | Chemistry |
| Abstract | The research was focused on the impact of different temperature (8 and 22 c) in the root zone on the activity of one of the major enzymes of ammonia assimilation – glutamine synthetase (GS) and free ammonia accumulation in the pea roots and nodules tissues (Pisum sativum L., cv. Marat) in the “blooming initiation” phase. GS was proven to act as a basic enzyme of bacteroid NH3 assimilation at low temperature in the root zone (8 c), whereas at optimal temperature (22 c) other enzymes associating ammonia are likely to participate in this process |

| Title | Job sequence modeling using Genetic Algorithms |
| Authors | Dr.S.N.Sivanandam , M.Kannan |
| Category | IT and Computing |
| Abstract | This paper presents a Genetic algorithm (GA) based procedure for finding an optimum job sequence for N jobs / M machines problem based on minimum elapsed time. The search space is so large that the Genetic algorithms outperform the conventional procedures in solving optimization problems. In this paper we propose a Bell shaped sequence for N jobs / M machines problem. The optimum sequence resemble a Bell shaped sequence (Normal or Gaussian distribution like curve). In the sense that the maximum total processing time of a job M machines lie in the middle of the sequence, next maximum lie in the right side (or left side) and the next maximum …. |

| Title | MATTER-SPACE POTENTIAL |
| Authors | ASAME IMONI OBIOMAH |
| Category | Physics, Astronomy |
| Abstract | This paper tackles the problem of the gravitational interactions between matter and space.
It gives accurate solutions including a mathematical definition for inertia. It employs common sense potential field laws, Maxwellian electromagnetism and a space similar to (though independent of) that postulated by Dirac in his concept of the particle - antiparticle relationship. The reasons for the seemingly anomalous relations between matter and space are arrived at naturally and logically |

| Authors | A.R. Abdul Rajak M. Nagendra Prasad , Dr.A.Shanmugam |
| Category | IT and Computing |
| Abstract | Mobile communication plays vital role in all areas of Engineering. Because of that, wireless medium is heavily crowded by various users in various applications. This medium adds much noise to the transmitted signal. Apart from this noise, it establishes multipath level between the transmitter and receiver. This multipath Communication will affect the signal reception at the receiver. Hence, OFDM is selected for Transmission. The main aim was to assess the overall performance of TCP\IP protocol suite….. |

| Title | Role of endogenous Phenolic compounds under infection of pea roots by Rhizobium leguminosarubv. viceae |
| Authors | Lyudmila E. Makarova, Galina P. Akimova, Marina G. Sokolova, Galina B. Luzova, Elena G. Rudikovskaya, Vadim N. Nurminsky |
| Category | Chemistry |
| Abstract | From 5mm sectors of etiolated pea seedlings roots cut along there were extracted “insoluble” and lipophilic “soluble” phenolic compounds. 48-hours old seedlings subjected to 24 hours infecting by Rhizobium leguminosarum bv. viceae were used as the initial material for the test (non-infected seedlings were used as control). The study was focused on the “soluble” phenolic compounds impact on Rhizobium propagation in liquid minimal medium. High sensibility of individual pea roots sectors to nodule bacteria infection was shown (by microscopical and microbiological methods) to be connected with low values in the tissues and low activity of the “soluble” phenolic compounds studied. … |

ADIABATIC FLOW THROUGH POROUS MEDIA |
| Authors | Galina St. Panayotova |
| Category | Mathematics |
| Abstract | In this paper we study the problem for existence of wave type solution for the quasi-linear system of compressible adiabatic flow through porous media. They are often considered in a variety of physical problems, where one encounters source terms that are balanced by internal forces.
It turns out that the problem for the existence of such solutions reduces to the problem of investigation of systems of Frobenius type, which is equivalent to a system of ordinary DEs and can be treated by standard methods |
