Hygeia : Journal for Drugs and Medicines , 2013,
Abstract: Plan: Anti-anxiety activity of Sida rhombifolia Linn.Prologue: Sida rhombifolia commonly called Bala or Atibala is claimed by folklorefor various ailments like rheumatism, seminal weakness, and diarrhea. Earlier studies on the ethanolic extract of theroots (SRE) revealed a significant, antioxidant, antimicrobial,anti-inflammatory, hepatoprotective and antibacterial activity. The presentstudy was designed to evaluate anti-anxiety activity of powdered whole plantextracts of Sida rhombifolia Linn. viz petroleum ether and ethanol.Methodology: Anti-anxiety activity of Sida rhombifolia Linn. were studied byusing Elevated Plus Maze (EPM) model in albino mice.Outcome: Albino mice were treated orally with dose 300 mg/kg of the extract andbehavior was observed on the EPM. Diazepam (2mg/kg, P.O) was used as a positivecontrol. Result showed that alcoholic extract was found to produce verysignificant result. Hence, this plant may be developed as a potentially usefulanti anxiety agent

FPGA Implementation of Audio Enhancement Using Adaptive LMS Filters

Journal of Artificial Intelligence , 2012,
Abstract: Digital audio has become very popular in the last two decades with the growth of multimedia systems and the World Wide Web. So, audio processing techniques such as filtering, equalization, noise suppression, compression, addition of sound effects and synthesis become necessary in the field of sound engineering. This study has presented some of the audio enhancement techniques using adaptive Least Mean Square (LMS) filters with the Field Programmable Gate Array (FPGA) Architectures which are developed using Xilinx System Generator (XSG). Verilog descriptions from XSG are synthesized to the target FPGA device-a Virtex4 xc4vsx55-12ff1148 and the resource utilization summary for the various alternate LMS architectures is obtained along with the Signal-to-Noise Ratio (SNR) calculations. Results show that Delayed LMS architectures provide a better SNR improvement at the cost of more resource utilizations.

The petroleum ether and ethanol extracts of powdered aerial part ofGloriosa superb Linn. were studied foranti-anxiety activity.Methodology: Anti-anxiety activity of G. supberbaLinn were studied by using Elevated PlusMaze (EPM) model in albino mice.Outcome: Albino mice weretreated orally with dose 300 mg/kg of the extracts and behavior was observed onthe EPM. Diazepam (2mg/kg, P.O) was used as a positive control. The resultsindicated that alcoholic extract exhibited significant result as compared tothe standard drug.Keywords: Gloriosa supberba Linn., Elevated plus Maze, anti-anxiety activity
A Software and a Hardware Interface for Reducing the Intensity Uncertainties Emitted by Vehicular Headlight on Highways

International Journal of Innovative Technology and Creative Engineering , 2011,
Abstract: This paper proposes a hardware and a software interface for reducing the effects of Headlight glare. It proposes a Fuzzy Sensor and a Fuzzy Controller that uses fuzzy rule based design approach to reduce the Headlight glare emitted by the oncoming vehicles during night on the Highways. This in fact reduces accidents and puts the driver of the oncoming vehicle in a safety zone which might jeopardize the oncoming driver’s visibility. In the conventional vehicles the illumination is adjusted manually by the driver. The proposed approach has the hardware circuit fit on to the Windshield, which provides ambient light source to oncoming vehicle, there by not producing blinding effect on the vision of the driver . This Hardware has to be fitted on to all the vehicles, so that it reduces the occurrence of accidents. Microcontrollers are usually designed to interface to and interact with electrical/electronic devices, sensors and high-tech gadgets to automate systems. Microcontrollers are used for automated decision making. The PIC microcontroller has been used which reduces the intensity of light if it goes beyond tolerable limits, affecting the driver’s vision. The concept of Fuzziness has been applied to the sensor and the Controller. The light intensity of the oncoming vehicle is received by the Fuzzy sensor. This input light intensity is fuzzified and checked for the tolerance limit. If this does not lie within the tolerance limit, the sensor passes it to the Fuzzy controller which converts it to an ambient light source and then on defuzzifying the output. The software has been developed using MATLAB.
Automatic Bridge Control System

International Journal of Electronics and Computer Science Engineering , 2012,
Abstract: Bridge vibration control is an important issue whose purpose is to extend the structural service life of bridges. Normally, the bridge is modeled as an elastic beam or plate subject to a moving vehicle. However, the moving truck on a bridge is a complicated problem that must still be researched. In this paper, wepropose a new method, to overcome the huge load in the bridge a load cell is used at the entry which will monitor the load continuously at both ends. To escape from the heavy water flow bridge vibrations alarm is used and it is connected with the water over flow sensor which will convert the heavy water flow signal into electrical signal and this electrical signal will make an alarm and close the gate of the bridge. When both the problem occurs at same time or at different time an alarm is generated and the bridges will automatically closed.

Intelligent Information Management (IIM) , 2010, DOI: 10.4236/iim.2010.211073
Abstract: Mathematical statement of elastodynamic contact problem for cracked body with considering unilateral restrictions and friction of the crack faces is done in classical and weak forms. Different variational formulations of unilateral contact problems with friction based on boundary variational principle are considered. Nonsmooth optimization algorithms of Udzawa’s type for solution of unilateral contact problem with friction have been developed. Convergence of the proposed algorithms has been studied numerically.
Precessing Ball Solitons as Self-Organizing Systems during a Phase Transition in a Ferromagnet  [PDF]
V. V. Nietz
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.410A3010

Precessing ball solitons (PBS) in a ferromagnet during the first order phase transition is induced by a magnetic field directed along the axis of anisotropy, while the action of the periodic field perpendicular to the main magnetic field has been analyzed. Under these conditions, the characteristics of arising equilibrium PBS are uniquely determined by the frequency of the periodic field, but the solitons with other frequencies are impossible. For such structure, the entropy increase connected with dissipation is compensated by the decrease of the entropy due to the external periodic field. It is shown that the equilibrium PBS are essentially the “self-organizing systems” that can arise spotaneously in a metastable state of ferromagnet.

Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.610155
Abstract: Precessing ball solitons (PBS) in a ferromagnet during the first order phase transition induced by a magnetic field directed along the axis of anisotropy, while the additional action of high-frequency field perpendicular to the main magnetic field, are analyzed. It is shown that the spatial motion of solitons, associated with thermal fluctuations in the crystal, does not destroy the equilibrium of self-organized PBS.
Lα Line of Dark Positronium as a Nongravitational Detection of DM  [PDF]

Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.613187
Abstract: An attempt to predict the new atomic dark matter lines is done on the example of a dark lepton atom-positronium. Its Layman-alpha line with the energy near 3 GeV may be observable if the appropriate conditions are realized. For this we have studied a γ-ray excess in the center of our galaxy. In principle, this excess may be produced by the Lα line of a dark positronium in the medium with Compton scattering. The possibility of observations of an annihilation line (E~300 TeV) of dark positronium is also predicted. Other proposals to observe the atomic dark matter are shortly described. Besides, Hα line (1.3μ) of usual positronum must be observable in the direction on the center of our galaxy.
