Modified SPLICE and its Extension to Non-Stereo Data for Noise Robust Speech Recognition

In this paper, a modification to the training process of the popular SPLICE algorithm has been proposed for noise robust speech recognition. The modification is based on feature correlations, and enables this stereo-based algorithm to improve the performance in all noise conditions, especially in unseen cases. Further, the modified framework is extended to work for non-stereo datasets where clean and noisy training utterances, but not stereo counterparts, are required. Finally, an MLLR-based computationally efficient run-time noise adaptation method in SPLICE framework has been proposed. The modified SPLICE shows 8.6% absolute improvement over SPLICE in Test C of Aurora-2 database, and 2.93% overall. Non-stereo method shows 10.37% and 6.93% absolute improvements over Aurora-2 and Aurora-4 baseline models respectively. Run-time adaptation shows 9.89% absolute improvement in modified framework as compared to SPLICE for Test C, and 4.96% overall w.r.t. standard MLLR adaptation on HMMs.Comment: Submitted to Automatic Speech Recognition and Understanding (ASRU) 2013 Worksho

Effect of alkali treatment on jute fibre composites

The aim of our project was the improvement of the mechanical properties of natural-fibrereinforced composites, as a result of optimization of the properties of jute fibres by the use of an NaOH treatment process. Jute fibres were subjected to a 5% alkali (NaOH) solution treatment for 0, 2, 4, 6 and 8 h at 30°C. The composites reinforced with alkali treated fibres showed improved mechanical properties. The improvement was maximum for the composites prepared with 4 h treated fibres. The ILSS improved by 26.56% and Bending Strength by 27.53%. An improvement in the crystallinity in the jute fibres increased its tenacity by 12%, 68% and 79% after 4, 6 and 8 h of treatment respectively. The rate of change of flexural strength and modulus were found to be linear with wt% of alkali treated fibres and the %breaking strain was reduced by 28% for composites prepared using 8-hr treated jute fibre. On plotting the different values of slopes obtained from the rates of improvement of the flexural strength and tenacity, against the NaOH treatment time, two different failure modes were apparent before and after 4 h of treatment. In the first region between 0 and 4 h, fibre pull out was predominant whereas in the second region between 6 and 8 h, transverse fracture occurred with a minimum fibre pull out. This observation was well supported by the SEM investigations of the fracture surfaces

Concept Based Dynamic Ontology Creation for Job Recommendation System

AbstractThe basis of our research is to construct a job recommendation system to the job seekers by collecting the job portals data. Due to huge amounts of the data in job portals the employers are facing difficulty in the identification of right candidate for the required skill and experience. The job seekers are also facing the problem of getting the suitability of the job based on their skill and experience. The knowledge acquisition based on the requirements is very difficult in case of huge amounts of the data sources. In fact classical development of domain ontology is typically entirely based on strong human participation. It does not adequately fit new applications requirements, because they need a more dynamic ontology and the possibility to manage a considerable quantity of concepts that human cannot achieve alone. The main focus of our work is to generate a job recommendation system with the details of job by taking account into the data posted in the web sites and data from the job seekers by the creation of dynamic ontology. We strongly believe that our system will give the best outcome in case of suitable job recommendation for both employers and job seekers without spending much time. To achieve this first we have extracted the data from various web pages and stored the collected data into .csv files. In the second stage the stored input files are used by the similarity measure and ontology creation module by generating the corresponding Web Ontology Language (.owl) file. The third stage is creating the ontology with the generated .owl by using protégé tool

ANTI STRESS EFFECT OF ASHWAGANDHA (WITHANIA SOMNIFERA) WILD AND CULTIVATED VARIETIES ON WORK RELATED PROFESSIONALS

Manas is the controller of Indriyas and the activities of Manas are the direct outcome of cerebral functions. There are three major Universal attributes (Mahagunas) of Manas namely Sattva, Rajas and Tamas. The variations in inter- individual as well as intra-individual leads to psychic behaviour. A study was conducted of Chittodvega anti-stress effect of Ashwagandha varieties on work related professionals. The study was conducted on 60 volunteers taken from T.T.D’s printing press, Tirupati. After screening, the selected volunteers were assigned three groups containing 20 patients each. The first and second groups served as the trial groups (I Group –WSN, II Group– WSWM) and third group (III Group - PG) served as the placebo control. Pre- Treatment and Post- treatment readings were recorded to assess various parameters of this study. Group I- Ashwagandha Nagori with milk (WSN) Group II– Ashwagandha wild with milk (WSWM) in a dose of 1gm were administered orally. The duration of the treatment was 40 days. Wheat powder placebo was given along with milk. Ashwagandha churna along with milk (WSN-Group I) and Ashwagandha churna purified with milk steam (WSWM -Group II) are taken as the test drugs and compared with the placebo group III. There is significant difference is observed in Group 2 better in headache, trembling of lips, neck & back pain, low sexual drive, diarrhoea, feeling of loneliness, reduced work productivity, frequent use of counter drugs, increased smoking and alcohol, sudden attacks of panic, frequent urination, excess anxiety, increased anger, depression, insomnia, difficulty concentration than Group 1. There is significant difference is observed in frequent sweating, dry mouth, and difficulty in making decision and weight gain or weight loss in Group 1 than Group 2

ANALYSIS OF THE ARSENIC IN COMMONLY USED MEDICINAL PLANTS

The demand for herbal products as food supplements, food additive and traditional medicine for health care is increasing globally. There are several reports of adverse effects of these herbal preparations due to the presence of high level of heavy metals such as Lead, Cadmium, Arsenic, Mercury, Chromium, Nickel, Copper etc and this problem has become a matter of concern. The present study was done to determine the presence of Arsenic in some of the selected medicinal plants namely Hemidesmus indicus (L.) R.Br. (Sariba), Cyperus rotundus L. (Musta), Glycyrrhiza glabra L. (Yashtimadhu), Rubia cordifolia L. (Manjishta), Eclipta alba Hassk (Bhringaraj), Hedychium spicatum Ham.ex Smith (Karchura), Emblica officinalis Gaertn. (Amalaki) and Acacia concinna (Willd.) DC. (Shikakai), which were procured from local market of Chennai, Tirupati and Hyderabad. The samples were digested by wet digestion method and analysed by UV-Vis Spectrophotometer. The results were compared with permissible limits recommended by WHO. Mean levels were evaluated with respect to their procurement. It was observed that the analyzed plant species contained safe levels of the heavy metals concentration excepting a very few samples. There was a considerable variation of heavy metal concentration for the examined medicinal plant species. This is due to the difference in physiological properties of plant uptake
