New Constructions of Edge Bimagic Graphs from Magic Graphs  [PDF]
Jayapal Baskar Babujee, Babitha Suresh
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.211197
Abstract: An edge magic total labeling of a graph G(V,E) with p vertices and q edges is a bijection f from the set of vertices and edges to such that for every edge uv in E, f(u) + f(uv) + f(v) is a constant k. If there exist two constants k1 and k2 such that the above sum is either k1 or k2, it is said to be an edge bimagic total labeling. A total edge magic (edge bimagic) graph is called a super edge magic (super edge bimagic) if f(V(G)) = . In this paper we define super edge edge-magic labeling and exhibit some interesting constructions related to Edge bimagic total labeling.

The Growth and the Optical, Mechanical, Dielectric and Photoconductivity Properties of a New Nonlinear Optical Crystal—L-Phenylalanine-4-nitrophenol NLO Single Crystal  [PDF]
Sagadevan Suresh
Journal of Crystallization Process and Technology (JCPT) , 2013, DOI: 10.4236/jcpt.2013.33014
Abstract: Nonlinear optical single crystals of L-phenylalanine-4-nitrophenol have been grown by the slow evaporation method. The grown crystal was subjected to the single crystal X-ray diffraction analysis, to confirm that it belongs to the monoclinic crystal structure, with space group P21. The optical transmission study reveals the transparency of the crystal in the entire visible region and the cut off wave length has been found to be 320 nm. The optical band gap is found to be 3.87 eV. The transmittance of the L-phenylalanine-4-nitrophenol crystal has been used to calculate the refractive index (n), the extinction coefficient (K) and the real (εr) and imaginary (εi) components of the dielectric constant. The mechanical behaviour of the grown crystals was studied using Vicker’s microhardness tester. The dielectric constant and dielectric loss of L-phenylalanine-4-nitrophenol are measured in the frequency range of 50 Hz to 5 MHz at different temperatures. The photoconductivity study confirms the negative photoconductive nature of the sample.

Mandibular Talon Cusp
Babitha GA,Shobha Prakash,Mithul Mishra
Indian Journal of Dental Advancements , 2011,
Abstract: Talon cusp is a developmental dental anomaly thought to arise as a result of evagination on the surface of a tooth crown before calcification has occurred. The etiology remains unknown. The incidence is 0. 04-10%. Any tooth may have a talon cusp but most of the cases involve maxillary lateral incisors, with some instances of bilateral involvement. The anomaly has been reported to be rare especially when it occurs on mandibular teeth. This article reports a case of talon cusp on permanent mandibular central incisor.

DISTANCE TWO LABELING FOR MULTI-STOREY GRAPHS
J.Baskar Babujee,S.Babitha
International Journal on Applications of Graph Theory in Wireless ad hoc Networks and Sensor Networks , 2010,
Abstract: An L (2, 1)-labeling of a graph G (also called distance two labeling) is a function f from the vertexset V (G) to the non negative integers {0,1,…, k }such that |f(x)-f(y)| 2 if d(x, y) =1 and | f(x)- f(y)| 1 ifd(x, y) =2. The L (2, 1)-labeling number (G) or span of G is the smallest k such that there is a f withmax {f (v) : v V(G)}= k. In this paper we introduce a new type of graph called multi-storey graph. Thedistance two labeling of multi-storey of path, cycle, Star graph, Grid, Planar graph with maximal edgesand its span value is determined. Further maximum upper bound span value for Multi-storey of simplegraph are discussed.AMS Subject Classification: 05C78
Fuzzy Controller Based 3Phase 4Wire Shunt Active Filter for Mitigation of Current Harmonics with Combined p-q and Id-Iq Control Strategies  [PDF]
Mikkili Suresh, Anup Kumar Panda, Y. Suresh
Energy and Power Engineering (EPE) , 2011, DOI: 10.4236/epe.2011.31007
Abstract: As more and more variable frequency drives (VFDs), electronic ballasts, battery chargers, and static Var compensators are installed in facilities, the problems related to harmonics are expected to get worse. As a result Active power filter (APF) gains much more attention due to excellent harmonic compensation. But still the performance of the active filter seems to be in contradictions with different control strategies. This paper presents detailed analysis to compare and elevate the performance of two control strategies for ex-tracting reference currents of shunt active filters under balanced, un-balanced and non-sinusoidal conditions by using Fuzzy controller. The well known methods, instantaneous real active and reactive power method (p-q) and active and reactive current method (id-iq) are two control methods which are extensively used in active filters. Extensive Simulations are carried out with fuzzy controller for both p-q and Id-Iq methods for different voltage conditions and adequate results were presented. Simulation results validate the superior per-formance of active and reactive current control strategy (id-iq) with fuzzy controller over active and reactive power control strategy (p-q) with fuzzy controller.
Emerging Asia’s Version of the Mundell-Fleming Model  [PDF]
Suresh Ramanathan, Kian Teng
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.49064
Abstract:

This paper explains the Mundell-Fleming model in the context of Emerging Asia economies management of capital mobility. Central Banks and Financial Regulators in Emerging Asia adopt a modified version of the model that incorporates two vital levers, a policy driven and a market driven method that is adaptable to the magnitude of capital flow. A policy combination mix of both policy and market driven provides smooth monetary policy signal transmission to exchange rates.

Unravelling Effects of Temperature and Soil Moisture Stress Response on Development of Dry Root Rot [Rhizoctonia bataticola (Taub.)] Butler in Chickpea  [PDF]
Mamta Sharma, Suresh Pande
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.43076
Abstract: Erratic rainfalls and rise in temperature have become more frequent under the changing scenario of climate particularly in semiarid tropics. As a consequence of it, a drastic shift of chickpea diseases have been recorded throughout the major chickpea growing regions in India and elsewhere. Dry root rot (DRR) caused by Rhizoctonia bataticola (Taub.) Butler [Pycnidial stage: Macrophomina phaseolina (Tassi) Goid] was found as a potentially emerging constraint to chickpea production than wilt (Fusarium oxysporum f. sp. ciceris). Increasing incidence of DRR indicate strong influence of climate change variables such as temperature and moisture on the development of disease. The present study therefore was conducted to quantify the role of temperature and soil moisture associated with infection, colonization and development of DRR under controlled environment. The DRR incidence was significantly affected by high temperature and soil moisture deficit. Out of five temperature regimes (15?C, 20?C, 25?C, 30?C and 35?C) and four moisture
Voltage Sag Characterization in a Distribution Systems: A Case Study  [PDF]
Suresh Kamble, Chandrashekhar Thorat
Journal of Power and Energy Engineering (JPEE) , 2014, DOI: 10.4236/jpee.2014.24074
Abstract: Voltage sags caused by the short-circuit faults in transmission and distribution lines have become one of the most important power quality problems facing industrial customers and utilities. Voltage sags are normally described by characteristics of both magnitude and duration, but phaseangle jump should be taken into account in identifying sag phenomena and finding their solutions. In this paper, voltage sags due to power system faults such as single phase-to-ground, phase-tophase, and two-phase-to-ground faults are characterized by using symmetrical component analysis and their effect on the magnitude variation and phase-angle jumps for each phase are examined. A simple and practical method is proposed for voltage sag detection, by calculating RMS voltage over a window of one-half cycle. The industrial distribution system at Bajaj hospital is taken as a case study. Simulation studies have been performed by using MATLAB/SIMULINK and the results are presented at various magnitudes, duration and phase-angle jumps.
