Some Studies on Semirings and Ordered Semirings
M. Amala, T. Vasanthi

Abstract: In this paper, we study the properties of Semirings and ordered semirings satisfying the identity a + ab = a. It is proved that Let (S, +, .) be a t.o.semiring satisfying the condition a + ab = a, for all a, b in S. If (S, +) is p.t.o (n.t.o), then (S, .) is non-positively ordered (non-negatively ordered).
Keywords: left singular semigroup, mono semiring, non-positively ordered, rectangular band. 2000 Mathematics Subject Classification: 20M10, 16Y60.

A Comparison between Flooding and Bloom Filter Based Multikeyword Search in Peer-To-Peer Network
Amulia P. M., Jisha G.

Abstract: P2P networks are popular in multikeyword searching systems. There are centralized and decentralized P2P networks. P2P systems can also be structured or unstructured. The common technique like flooding used in unstructured network for keyword search incurs large amount of unnecessary traffic. The bloom filter technique used in keyword search reduces unnecessary traffic in the network. With user demand becoming complex and broad, multikeyword search is becoming popular. This paper gives a comparison between flooding and bloom filter based multikeyword search techniques.

Chemistry of Ground Waters Containing High Fluoride in Boudh District, Orissa
S. K. Srivastava, Y. Satya Kumar, J. S. Bhargav

Abstract: Monitoring of National Hydrograph Network Stations of Central Ground Water Board, in Boudh district has been used in identifying the high Fluoride containing wells in Harbhanga Block. Detailed reappraisal studies with a closer sampling in the particular area revealed presence of high Fluoride along two tracts. Analysis of the data has been used to study the geochemistry of ground waters and the probable source of high Fluoride in these waters.

Research Analysis and Design of Geometric Transformations using Affine Geometry
N. V. Narendra Babu, Prof. Dr. G. Manoj Someswar, Ch. Dhanunjaya Rao

Abstract: In this research paper, we focus on affine transformations of the coordinate system. The affine transformation consists of linear transformations (rotation, scaling, and shear) and a translation (shift). It provides a good approximation for the changes in pose of objects that are relatively far from the camera. The affine transformation also serves as the basic block in the analysis and registration of general and non rigid geometric transformations. When the area considered is small enough, the affine transformation serves as a first-order Taylor series approximation of any differentiable geometric transformation.
Keywords: geometric transformation, global algorithms, geometric-radiometric estimation, structured images, textured images, affine space, collinearity.

Microsphere Formation Using an Excimer Laser
Ryan P. Lu, Christopher K. Huynh, Joshua M. Kvavle, Ayax D. Ramirez

Abstract: Silicon microspheres 800 nm to 10 m have been formed using an excimer laser. The method described in this paper shows that microspheres can be formed with high yield and free of contamination. Silicon microspheres enable new applications where silica microspheres fall short. Due to their semiconducting properties, new photonic devices can be developed for nano-electro-optical applications.

Innovative Improvement of Data Storage Using Error Correction Codes
Aru Okereke Eze, Emole Chukwuemeka Enoch, Enyenihi Henry Johnson

Abstract: The need for codes capable of detecting and correcting byte errors are extremely important since many memory systems use b-bit-per-chip organization. Error correcting codes have been used to enhance the reliability and data integrity of computer memory systems (information-bearing objects); data-storage systems are natural consumers of information theoretic ideas. For many issues in data-storage systems, the best trade-off between cost, performance and reliability, passes through.............

Magneto hydrodynamic Couple stress Squeeze Film Lubrication of Triangular Plates
Biradar Kashinath

Abstract: In this paper the analysis of the effect of transverse magnetic field on the couple stress squeeze film lubrication between triangular plates is presented. The modified Reynolds equation is derived. The closed form expressions are obtained for the MHD squeeze film pressure, load carrying capacity and squeeze film time. The results are presented for different values of operating parameters. It is observed, that the effect of applied magnetic field on the squeeze film lubrication between triangular plates with couple stress fluids is to increase the load carrying capacity significantly and to delay the time of approach as compared to the corresponding non-magnetic case.

Abhinav, J Ranga

Abstract: A hybrid modulation technique consisting of single-reference six pulse modulation (SRSPM) for front end dc/dc converter and 33% modulation to the three-phase inverter. Applying proposed SRSPM to control front-end dc/dc converter, high frequency (HF) pulsating dc voltage waveform is produced, that is equivalent to six-pulse output at 6× line frequency (rectified 6-pulse output of balanced three-phase ac waveforms) once averaged. It reduces the control complexity........
