Abstract: A convenient and user –friendly interface for information retrieval through computer is an important issue. Speechbeing natural mode of communication among human beings has the potential of being a primary as well as convenient modeof interaction with computer. This is a good reason for building systems that communicate with users via speech. Marathi isone of the most widely used language is Maharashtra .An interesting domain for such speech understanding systems isinformation dialogs where the user wants to get some information by asking the system which takes the role of an “IntelligentMachine” in the field of interest. Speech recognition having much more application in health sector In order to make such acommunication process possible we explore the new approach of Polly Clinic Inquiry System using Marathi SpeechRecognition.

Abstract: Gender is an important and most diffrentiative characteristic of a speech. Gender information can also be used to improve the performance of speech and speaker recognition systems. Automatic gender classification is a technique that aims to determine the sex of the speaker through speech signal analysis. However with the increase in biometric security application, practical application of gender identification increased the many fold .The need of gender identification from speech arises several situation such as sorting telephonic call. Many methods of gender identification have been proposed in literature. We implemented the gender classification method and gender dependant feature such as pitch, roll of and energy in combination with MFCC. The clustered approach of above said parameter is implemented using SVM. We also present the experimental result of the proposed approach .It is observed that the accuracy of gender identification system is improved on the basis of size of codebook .The high accuracy is got at 25 codebook size with greater time slice. The accuracy of system tested with respective to gender and age .The efficient recognition rate of 95% is achieved in the age group of 25-30.

Abstract: This paper focuses on number recognition from feature extracted using Electroencephalogram (EEG) readings. EEG signals were recorded at Department of Computer Science and IT, Dr. B. A. M. University, India, from 6 volunteer subjects. A random number generator Graphics User Interface was developed in VB7. It is used to display numbers from 0 to 9 which worked as Visually Evoked Potential (VEP) for the experiment. The database of 6 male right-handed subjects in the age group of (20-25) was created and used as training data set. By exposing the same set of subjects to the GUI again, new EEG recordings were collected. This new set of EEG readings was considered as testing data set. The testing data was searched and matched with trained data set for recognizing pattern of each number. The experiments were conducted by concentrating on Beta signal and Linear discriminate analysis (LDA) was implemented to classify the data. The recognition rate observed was different for different numbers. Overall recognition rate observed was 68.33%. It is also seen that there exist a unique pattern for each number.

Abstract: Importance of Elliptic Curves in Cryptography was independently proposed by Neal Koblitz and Victor Miller in 1985.Since then, Elliptic curve cryptography or ECC has evolved as a vast field for public key cryptography (PKC) systems. In PKC system, we use separate keys to encode and decode the data. Since one of the keys is distributed publicly in PKC systems, the strength of security depends on large key size. The mathematical problems of prime factorization and discrete logarithm are previously used in PKC systems. ECC has proved to provide same level of security with relatively small key sizes. The research in the field of ECC is mostly focused on its implementation on application specific systems. Such systems have restricted resources like storage, processing speed and domain specific CPU architecture.

Abstract: Managing the transactions in real time distributed computing system is not easy, as it hasheterogeneously networked computers to solve a single problem. If a transaction runs acrosssome different sites, it may commit at some sites and may failure at another site, leading to aninconsistent transaction. The complexity is increase in real time applications by placingdeadlines on the response time of the database system and transactions processing. Such asystem needs to process Transactions before these deadlines expired. A series of simulationstudy have been performed to analyze the performance under different transaction managementunder conditions such as different workloads, distribution methods, execution mode-distributionand parallel etc. The scheduling of data accesses are done in order to meet their deadlines andto minimize the number of transactions that missed deadlines. A new concept is introduced tomanage the transactions in dynamic ways rather than setting computing parameters in staticways. With this approach, the system gives a significant improvement in performance.
Vegetable fibers as multifunctional materials
Amico, S.C.;
Matéria (Rio de Janeiro) , 2010, DOI: 10.1590/S1517-70762010000200037
Abstract: concerns related to the ever-growing use of raw-materials from non-renewable sources by modern society is driving the interest of the academic and scientific sectors for a new concept of material, which takes into account not only mechanical performance, cost and availability, but also environmentally-related issues, such as biodegradability, renewability and energy use, along with the promotion of social and economical development of the economically-challenged segment of the population. vegetable fibers have been used in many home-made objects, such as ropes and artcraft, for perhaps as long as humanity exists. however, these fibers present a combination of interesting properties which enables their use in a wide variety of sectors. this invited article will review the work recently carried out by the author in collaboration with various researchers from ufrgs, ufpr and ucs, and will be divided into three case studies, focusing on the use of vegetable fibers for oil sorption, as infiltration (flow) medium and as reinforcement for polymer composites, promoting their use in more demanding and rewarding applications.

Medicine : Science or Art?

Abstract: Debate over the status of medicine as an Art or Science continues. The aim of this paper is to discuss the meaning of Art and Science in terms of medicine, and to find out to what extent they have their roots in the field of medical practice. What is analysed is whether medicine is an "art based on science"; or, the "art of medicine" has lost its sheen (what with the rapid advancements of science in course of time, which has made present day medicine more sophisticated). What is also analysed is whether the "science of medicine" is a pure one, or merely applied science; or the element of science in it is full of uncertainty, simply because what is accepted as "scientific" today is discarded by medical practitioners tomorrow in the light of newer evidence. The paper also briefly touches upon how, in the field of present medical education, the introduction of medical humanities or humanistic education has the potential to swing the pendulum of medicine more towards the lost "art of medicine". The paper concludes by saying that the art and science of medicine are complementary. For successful practice, a doctor has to be an artist armed with basic scientific knowledge in medicine.
Integrated management of web blight of urd and mung bean
Indian Phytopathology , 2012,
Abstract: The treatment combinations based on bio-agent Gliocladium virens (Trichoderma virens), Karanj (Pongamia glabra) cake, carboxin and Rhizobium were evaluated in integration of three methods as soil application,foliar spray and seed treatment for the management of web blight of urd (Vigna mungo) and mung (Vigna radiata) bean caused by Thanatephorus cucumeris (=Rhizoctonia solam) under sick field conditions. The integration of soil application of Karanj cake (2 q ha'), seed treatment with G. virens (10 6 spores/ml/10g seed) + carboxin (1 g kg-1)+ Rhizobium sp.
