A NOVEL DESIGN OF REVERSIBLE SERIAL AND PARALLEL ADDER/SUBTRACTOR
KRISHNAVENI.D,,GEETHA PRIYA.M
International Journal of Engineering Science and Technology , 2011,
Abstract: Under ideal conditions, Reversible logic gates produce zero power dissipation. So these can be used for low power VLSI design. This paper proposes a new reversible parallel adder/subtractor using 4*4 Reversible DKG gate that can work singly as a reversible full adder and a full subtractor. A serial adder/subtractor is also designed in this paper using Reversible Universal Shift registers and DKG gate.This paper provides a threshold to build more complex arithmetic systems using reversible logic.
Suitable Site Selection of Decentralised Treatment Plants Using Multicriteria Approach in GIS  [PDF]
K. Deepa, M. Krishnaveni
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.43030
Abstract: Metropolitan cities like Chennai facing rapid urbanisation. This results in informal extension of cities in peri-urban and rural areas. Once the city expands the problem arising is the water supply and sewage treatment system. In the present work an attempt is made in site suitable selection of Decentralised treatment plants (DCTP) with appropriate waste water treatment technologies using GIS techniques. Multicriteria analysis were performed by the combination of Analytical Hierarchy Process (AHP). Six thematic maps were considered such as population density map, landuse map, slope map, soil map, cost map and technology. Different classes were identified for each thematic maps. Using Analytical Hierarchy Principle (AHP) [1] (Saaty, 2000), a paired comparison matrix was prepared for criteria classes and individual class weights and map scores were worked out. These weights were applied in linear summation equation to obtain a unified weight map containing due weights of all input variables. Finally all the weighted maps were reclassified to arrive the best suitable site location of decentralised treatment plants.
Helicobacter pylori infection in relation to gastric cancer progression
Venkateshwari A,Krishnaveni D,Venugopal S,Shashikumar P
Indian Journal of Cancer , 2011,
Abstract: Gastric cancer is a major cause of cancer death worldwide, especially in developing countries. The incidence of gastric cancer varies from country to country, probably as a result of genetic, epigenetic, and environmental factors. H. pylori infection is considered as a major risk factor in the development of gastric cancer. However, the scenario varies in Asian countries, exhibiting a higher rate of H. pylori infection and low incidence of gastric cancer, which could be attributed to strain-specific virulence factors and host genetic makeup. In this review, we discuss the various virulence factors expressed by this bacterium and their interaction with the host factors, to influence pathogenesis.
Agrobacterium-Mediated Transformation of indica Rice (Oryza sativa L.), IR64 with Mungbean LEA Protein Gene for Water-Stress Tolerance
S. Rajesh,S. Krishnaveni,D. Sudhakar,M. Raveendran
American Journal of Plant Physiology , 2008,
Abstract: Late embryogenesis abundant proteins are associated with tolerance to water-stress resulting from desiccation and cold shock. A LEA protein gene, emv2 from Vigna radiata was sense expressed into indica rice cultivar IR 64 to produce plants tolerant to limited water stress situations. Mature seed-derived embryogenic calli were transformed with Agrobacterium strain LBA 4404 harboring the binary vector pCEMV2 with mungbean emv2 gene. Active proliferating resistant calli selected in hygromycin and cefotaxime were regenerated and transferred to half-MS rooting medium. The putative transgenic rice plants expressing emv2 were analyzed for integration of the transgene through polymerase chain reaction and tested positive for hph and emv2 genes.
A New Leakage Power Reduction Technique for CMOS VLSI Circuits
M. Geetha Priya,K. Baskaran,D. Krishnaveni,S. Srinivasan
Journal of Artificial Intelligence , 2012,
Abstract: A robust method which is equally effectual for static power control in CMOS VLSI circuits for System on Chip (Soc) applications in deep submicron technologies is proposed. Referring to the International Technology Roadmap for Semiconductors (ITRS), the total power dissipation may be significantly contributed by leakage power dissipation. To reduce leakage the proposed method introduces two self controlled stacked leakage control transistors (LT) between Vdd and ground, which offers high resistance, when it is in off state. The gate and substrate of each LT’s are tied together to introduce Dynamic Threshold voltage MOSFET (DTMOS). This proposed method is intuitively momentous and leads to better performance measure in terms of dynamic power, leakage power propagation delay and Power Delay Product (PDP) with standard threshold devices. The experiment and simulation results show that the proposed method effectively outperforms than the base case with little area overhead.
Design of OFDM Transceiver for LTE System—A Survey  [PDF]
Nivish Vishnumohan, Krishnaveni Vellingiri, Kesavamurthy Thangavelu
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2015, DOI: 10.4236/ijcns.2015.86023
Abstract: LTE (Long Term Evolution) is the latest technology in wireless communication. It is being used because of its peak data rate and spectral efficiency. LTE uses OFDMA (Orthogonal Frequency Division Multiple Access) technology for radio transmission and reception in downlink. OFDM is a multicarrier modulation and multiplexing technique to improve data rate, spectral efficiency and minimize the problem of fading and ISI (Inter Symbol Interference). Many transceivers design have been designed for OFDM system to minimize error and maximize throughput of the information being transmitted and received at the system. The purpose of this article is to present a survey of the published literature which deals with various OFDM transceiver design, focusing on the merits and demerits of the corresponding OFDM transceiver design.
Evaluation of plant-derived commercial products for blast and sheath blight control in rice
K. MURALlDHARAN, C.S. REDDY, D. KRISHNAVENI and G.S. LAHA
Indian Phytopathology , 2012,
Abstract: Commercial plant-derived products with or without the active principle azadirachtin, were tested for 5-yearsat 12 sites endemic to rice blast or at 9 sites endemic to sheath blight disease. Most plant-derived products tested reduced disease severity, and also increased grain yield harvests. The degree of disease reductionand yield increase was more pronounced when these products were applied to control blast. The plant-derivedproducts may serve as an effective component in integrated management of rice blast and sheath blight diseases.

Indian Phytopathology , 2012,
Abstract: Rice genotypes carrying resistance genes to blast disease were evaluated in multi-environment tests (METs). Tadukan carrying resistance gene Pi-ta showed small lesions infecting <2% leaf area indicating a very high level of durable resistance to blast disease. The METs clearly demonstrated the expression of a high degree of resistance in A57 carrying three resistance genes (Pi-1, Pi-2 and Pi-4). A57 was identified as the best line that exhibited resistance to blast across the country in all rice growing environments, irrespective of ecosystems. The performance of BL 245 with two resistance genes (Pi-2 and Pi-4) and C101LAC (Pi-1) was comparable to A57. The performance of these NILs was marginally superior to the resistant checks (Tadukan, Rasi, Tetep and IR 64) and the international blast differential Raminad Strain 3. Alleles for the genes identified as effective and durable in the METs in this study must be located in our cultivars besides discovering newer ones to effectively utilize resistance genes in future.
