An Analytical Framework for the Assessment of the Mobile IP Overhead Involved in the Integrated Internet-MANET
Khaleel Ur Rahman Khan,Rafi U Zaman,A Venugopal Reddy
International Journal of Interactive Mobile Technologies (iJIM) , 2010, DOI: 10.3991/ijim.v4i1.1027
Abstract: Quite a few strategies have been proposed for integrating mobile ad hoc networks and the Internet. A need has been felt for an analytical model that would facilitate a formal definition and comparison of different integration strategies without actually implementing them in a simulated environment. In this paper, we present an analytical framework based on the concept of a Relay Path Set (RPS). This model can be used to describe, compare the different strategies for integrating mobile Ad Hoc networks and the Internet, propose new strategies and suggest improvements in the existing strategies at different module levels. The proposed model has been applied on a few of the existing Integration strategies and performance comparison has also been made. We also discuss the future work that can be carried out using the proposed framework.
In vitro susceptibility of dermatophytes to itraconazole
Venugopal Pankajalakshmi,Venugopal Taralakshmi
Indian Journal of Dermatology, Venereology and Leprology , 1992,
Abstract: The in vitro activity of itraconazole was investigated against 88 clinical isolates of dermatophytes. The isolates included Microsporum canis-50, M. audovinii-5, Trichophyton rubrum-6, T. mentagraphytes-5 T.violaceum-12, T.simii-5, T verrucosum-1, T.soundanense-1, T. erinacei-1 and Epidermophyton flooccosum-2 isolates. The results were compared with that of ketoconazole and griseofulvin. Itraconazole was more active, inhibiting 85 of the 88 isolates at a concentration of 0.5 μg/ml (MIC range 0.01-1 μg/ml). Ketoconazole (MIC range 0.1-10 μg/ml) required 2.5 μg/ml and 5 μg/ml of the drug respectively for inhibition of all the isolates except one of Microsporum species.
Low Power Reversible Parallel Binary Adder/Subtractor
Rangaraju H G,Venugopal U,Muralidhara K N,Raja K B
International Journal of VLSI Design & Communication Systems , 2010,
Abstract: In recent years, Reversible Logic is becoming more and more prominent technology having its applications inLow Power CMOS, Quantum Computing, Nanotechnology, and Optical Computing. Reversibility plays animportant role when energy efficient computations are considered. In this paper, Reversible eight-bit ParallelBinary Adder/Subtractor with Design I, Design II and Design III are proposed. In all the three designapproaches, the full Adder and Subtractors are realized in a single unit as compared to only full Subtractorin the existing design. The performance analysis is verified using number reversible gates, Garbageinput/outputs and Quantum Cost. It is observed that Reversible eight-bit Parallel Binary Adder/Subtractorwith Design III is efficient compared to Design I, Design II and existing design

Android Note Manager Application for People with Visual Impairment
Gayatri Venugopal
Computer Science , 2013, DOI: 10.5121/ijmnct.2013.3502
Abstract: With the outburst of smart-phones today, the market is exploding with various mobile applications. This paper proposes an application using which visually impaired people can type a note in Grade 1 Braille and save it in the external memory of their smart-phone. The application also shows intelligence by activating reminders and/or calling certain contacts based on the content in the notes.
A Review of Popular Applications on Google Play - Do They Cater to Visually Impaired Users?
Gayatri Venugopal
Computer Science , 2015, DOI: 10.17485/ijst/2015/v8iS4/61436
Abstract: The number of applications on online mobile application stores is increasing at a rapid rate. Smart-phones are used by a wide range of people varying in age, and also in the ability to use a smart phone. With the increasing dependency on smart-phones, the paper aims to determine whether the popular applications on Google Play, the official store for Android applications, can be used by people with vision impairment. The accessibility of the applications was tested using an external keyboard, and TalkBack, an accessibility tool developed by Google. It was found that several popular applications on the store were not designed keeping accessibility in mind. It was observed that there exists a weak positive relationship between the popularity of the application and its accessibility. A framework is proposed that can be used by developers to improve the accessibility of an application. The paper also discusses the programming aspects to be considered while developing an Android application, so that the application can be used by sighted as well as visually impaired users.
Mathematical model for steady state current at ppo-modified micro-cylinder biosensors  [PDF]
K. Venugopal, A. Eswari, L. Rajendran
Journal of Biomedical Science and Engineering (JBiSE) , 2011, DOI: 10.4236/jbise.2011.49079
Abstract: A Mathemataical model for a modified micro- cylinder electrode in which polyphenol oxidase ( PPO) occurs for all values of the concentration of catechol and o-quinone is analysed. This model is based on system of reaction-diffusion Equations containing a non-linear term related to Michaelis Menten kinetics of the enzymatic reaction. Here a new analytical technique Homotopy Perturbation Method is used to solve the system of non-linear differential Equations that describe the diffusion coupled with a Michaelis-Menten kinetics law. Here we report an analytical expressions pretaining to the concentration of catechol and o-quinone and corresponding current in terms of dimensionless reaction-diffusion parameters in closed form. An excellent agreement with available limiting case is noticed.
X-Ray Diffraction Studies of Rice Husk Ash—An Ecofriendly Concrete at Different Temperatures  [PDF]
Patnaikuni Chandan Kumar, Nutulapati V. S. Venugopal
American Journal of Analytical Chemistry (AJAC) , 2013, DOI: 10.4236/ajac.2013.48046
Abstract:

In the majority of rice producing countries, much of the husk produced from the processing of rice is either burnt or dumped as waste. Rice husks are one of the largest readily available but most under-utilized biomass resources, being an ideal fuel for electricity generation. In this communication the author reported the X-ray diffraction studies on rice husk ash (RHA) concrete samples heated at 300℃ and 1000℃ which were compared and observed that at 300℃ the inner surface of the specimen shows an extra compound. Copper Iron Lead Telluride Cu3FePbTe4 along with SiO2, Al5Fe2ZnO4 was present on the surface which also and might be responsible for imparting additional strength to 7.5% RHA concrete at 300℃. The X-ray diffraction studies of samples exposed to 1000℃ on temperature showed that the additional chemical compounds formed at lower temperatures were not found at 1000℃ at outer and inner surfaces of the sample indicating its possible reason for
