Journal of Artificial Intelligence , 2013,
Abstract: Cloud computing plays a major role in Internet based environment to offer any kind of services. The service can be accessed from anywhere and any time. Reconfigurable hardware, the Field Programmable Gate Array (FPGA) is to provide rapid switching from one service to another service by reconfiguration. It also facilitates dynamic partial reconfiguration. This study proposes a general architecture by blending cloud and FPGA.

Abstract: Stress testing is a part of development strategy under the ICH requirements and carried out under more severe conditions than accelerated stability studies. The objective of the present study was to develop an accurate and precise stability indicating liquid chromatography-mass spectrometric method for the antibiotic Gemifloxacin Mesylate. The drug was subjected to acid, base hydrolysis (1M HCl &1M NaOH) and oxidative decomposition (30%v/v H2O2). The study was carried out from room temperature to 70 C and observed for 10% decomposition. The products formed under different stress condition were investigated by using LC-MS. Analyses were separated on a C18 column (Phenomenax, 250x4.6mm) with mobile phase composed of ammonium acetate : acetonitrile (pH 7.1, 10:90 %v/v) pumped at 1 ml/min. The detection was at 270nm. Retention time of Gemifloxacin Mesylate was found to be 8.9 min. whereas, retention time of acid and base degradant products were 6.2, 7.7 min and 6.0, 7.8 min, respectively. Retention time of oxidative degradant product was found at 7.8 min. Mass Spectrometry was used to characterize the degradation products and the probable structures have been elucidated. The method was validated in accordance with ICH guidelines to ensure its suitability. As the developed method is stability indicating it could be used in drug development and drug testing laboratory for the quality control of Gemifloxacin Mesylate.

International Journal of Innovative Technology and Exploring Engineering , 2012,
Abstract: In the recent past, Security-sensitive applications, such as electronic transaction processing systems, stock quote update systems, which require high quality of security to guarantee authentication, integrity, and confidentiality of information, have adopted Heterogeneous Distributed System (HDS) as their platforms.We systematically design a security-driven scheduling architecture that can dynamically measure the trust level of each node in the system by using differential equations and introduce SRank to estimate security overhead of critical tasks using SDS algorithm.Furthermore,we can achieve high quality of security for applications by using security-driven scheduling algorithm for DAGs in terms of minimizing the makespan, risk probability, and speedup. In addition to that the fault tolerant is included using Security Driven Fault Tolerant Scheduling Algorithm (SDFT) to tolerate N processors failure at one time, and it introduced a new global scheduler to improve efficiency of scheduling process.Moreover, the SDFT supported flexible security policy applied on real time tasks according to its security requirement and considered the effect of security overhead during scheduling. We also observe that the improvement obtained by our algorithm increases as the security-sensitive data of applications increases.
Continuous supply chain collaboration: Road to achieve operational excellence
N. Senthil Kumar,P. Subburethina Bharathi
Management Science Letters , 2011,
Abstract: Supply chain management (SCM) is becoming critical as firms recognize that competition is shifting from company versus company to supply chain versus supply chain. In the present competitive scenario, the fierce competition has driven most companies to seek for means of enhancing performance beyond their four wall boundaries. The firm’s ability in collaborating with its upstream and downstream partners determines its success in attaining better performance with supply chain collaboration; a firm is able to serve fragmented markets in which end customers require more product varieties and availability with shorter product life cycle and, at the same time, lower supply chain costs. This paper introduces the framework of continuous supply chain collaboration (CSCC), which extends the traditional frame of reference in strategic sourcing from a supplier centric to a supply-chain-scope as continuous improvement efforts to enhance the customer satisfaction. CSCC practices are rather exceptional, yet CSCC is believed to be the single most comprehensive framework for attaining operational excellence.
Enhanced thermopower upon Ni substitution in Na0.75CoO2
N. Gayathri,A. Bharathi,Y. Hariharan
Physics , 2005,
Abstract: Thermopower measurements have been carried out on the Ni substituted samples of Na0.75CoO2 in the temperature range 4.2K to 300K. The room temperature TEP increases by 20microV/K even with 1% Ni substitution and systematically increases with increasing Ni content upto 5%. The increase in TEP is accompanied by a decrease in rho, thus increasing the ratio of S^(2)/rho on Ni substitution. At low T, the TEP shows an anomaly in the substituted samples, showing a peak at T ~ 20K.
Polaronic transport in the ferromagnetic phase of Gd1-xCaxBaCo2O5.53
N. Thirumurugan,C. S. Sundar,A. Bharathi
Physics , 2011,
Abstract: Temperature dependent electrical resistivity and thermopower measurements were carried out on Gd1-xCaxBaCo2O5.53 with x varying between 0 and 0.25. Ca subsitution leads to the incorporation of holes (Co4+) into the system that leads to a reduction in resistivity and a stabilisation of the ferromagnetic phase at low temperatures. The temperature dependence of resistivity and thermopower are markedly different in the Ca doped sample, with a dramatic reduction in the resistivity, as compared to that in the pristine sample. The variation in both the resistivity and thermopower with temperature is explained in terms of the transport of polarons in the ferromagnetic phase of Ca doped system.
Intelligent Control of pH in a Neutralization Process
N. Bharathi,J. Shanmugam,T.R. Rangaswamy
Asian Journal of Information Technology , 2012,
Abstract: In the present study, control of pH neutralization process using neural and fuzzy controller is proposed. Initially a conventional PI controller based on the Relay Feedback method is tried to control the pH at different linear regions. Control of pH by conventional PI controller based on the local linear model fails to provide satisfactory performance over the entire region. Hence to overcome this drawback a Neuro controller with inverse model anticipation and a fuzzy controller are used. In this study a novel fuzzy controller is used. Most fuzzy controllers use control error (e) and change in the control error ( e) as controller inputs and not able to differentiate the region in which process operates. This controller uses set point as third input to select the region in which the process is operating. An experimental study of the performance of the intelligent controllers designed is carried out on a pilot plant in the lab.

Abstract: Development of drought resistant cotton cultivars has long been a major breeding objective, since water stress limits fiber production and productivity. Recent advances in functional genomics can increase the efficiency of conventional breeding for genetic improvement of crop plants for improved abiotic stress resistance. To this end, a novel drought resistance gene was identified by comparing the gene expression profile of Gossypium hirsutum cv KC3 and MCU12 by employing a cDNA-RAPD approach. Physiological and biochemical studies showed that KC3 has relatively better drought tolerance than MCU12. Among 25 random primers, OPA15 has identified differentially expressed cDNA in KC3. Results of BLASTP algorithm have shown that this cDNA has significant homology with P-Glycoprotein, ACC oxidase2 and ABC transporter which are involved either directly, or indirectly, in stress tolerance in animals and plants. Hence, the cDNA sequence identified in this study may be a novel gene that confers drought resistance in cotton as KC3 is well adapted and is widely cultivated in rain-fed tracts of Tamil Nadu, India. Further characterization of this gene may show it has potential application for development of cotton with improved drought resistance, through genetic engineering and/or marker aided selection (MAS)

Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.76055
Abstract: The rise in the price of oil and pollution issues has increased the interest on the development of electric vehicles. This paper discusses about the application of solar energy to power up the vehicle. The basic principle of solar based electric vehicle is to use energy that is stored in a battery to drive the motor and it moves the vehicle in forward or reverse direction. The Photo Voltaic (PV) module may be connected either in parallel or series, and the charge controllers direct this solar power to the batteries. The DC voltage from the PV panel is then boosted up using a boost DC-DC converter, and then an inverter, where DC power is converted to AC power, ultimately runs the Brushless DC motor which is used as the drive motor for the vehicle application. This paper focuses on the design, simulation and implementation of the various components, namely: solar panel, charge controller, battery, DC-DC boost converter, DC-AC power converter (inverter circuit) and BLDC motor for the vehicle application. All these components are modeled in MATLAB/SIMULINK and in real-time, the hardware integration of the system is developed and tested to verify the simulation results.
