For the purpose of human authentication, the face recognition system is use as a biometric mode. As we know the face recognition is a technique of recognizing similar faces from face databases. It is the problem of searching a face in reference database to find the matches as a given face. The purpose is to find a face that has highest similarity with a given face in the database. The objective of face recognition involves the extraction of different features of the human face from the face image for discriminating it from other persons. Many face recognition algorithms have been developed and used as an application of access control and surveillance. For enhancing the performance and accuracy of biometric face recognition system, we use a multi-algorithmic approach, where in a combination of three different individual face recognition techniques is used. Recently, we developed six face recognition systems based on the six combinations of four individual techniques of face recognition system by fusing the scores of two approaches in a single face recognition system. In this paper, we develop four different face recognition systems based on the combinations of four individual techniques namely Principal Component Analysis (PCA), Discrete Cosine Transform (DCT), Template Matching using Correlation and Partitioned Iterative Function System (PIFS). We fuse the scores of three of these four techniques in a single face recognition system. We perform a comparative study of face recognition rate of these face recognition systems at two precision levels namely at top- 5 and at top-10. We experiment with a standard database called ORL face database. Experimentally, we find that each of these four systems perform well in comparison to the corresponding (in group of two) six combinations of four individual techniques. Overall, the system based on combination of PCA, DCT and Template Matching using Correlation is giving the best performance among these four systems.Keywords

Objective: The present study was designed to investigate underlying molecular mechanism for antitumorigenic potential of Terminalia chebula (TC) against chemically-induced skin tumorigenesis in Swiss albino mice. It is used as herbal medicine because it exhibits antioxidant, anti-inflammatory, and anticarcinogenic activity. However, the précised underlying mechanism remains to be elucidated. Materials and Methods: In light of the important role of nuclear factor-kappaB (NF-κB), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (i-NOS), ornithine decarboxylase (ODC), proinflammatory cytokines, oxidative stress in carcinogenesis, chemopreventive efficacy of TC against 7,12-dimethylbenz[a] anthracene (DMBA), and croton oil-induced 2-stage skin carcinogenesis was studied in terms of cytoprotective antioxidant enzymes activity, lipid peroxidation (LPO), inflammatory responses, and expression of various molecular markers in skin tissues. Results: We found that topical application of TC at dose of 30 mg/kg b. wt. mouse effectively suppressed oxidative stress and deregulated activation of inflammatory mediators and tumorigenesis. Histological findings further supported the protective effects of TC against DMBA/croton oil-induced cutaneous damage. Conclusion: The findings of the present study suggest that the chemopreventive effect of TC is associated with upregulation of endogenous cytoprotective machinery and downregulation of inflammatory mediators (inhterleukin (IL)-6, COX-2, i-NOS, ODC, and NF-κB).Keywords

Alpha Ketoglutaric Acid (AKG), one of two ketone derivatives of glutaric acid is an important biological compound that serves as a natural scavenger of ammonium ion, facilitating its conversion to amino acids and protein. AKG inhalation has potential therapeutic role against ammonia-induced structural and inflammatory changes in the lungs. In the present study sub-acute inhalation toxicity of a novel submicronic AKG respiratory formulation was evaluated in Sprague Dawley rats. Sub-acute inhalation toxicity study of novel AKG respiratory formulation at doses, 1, 3 and 5% was conducted as per Schedule-'Y' guidelines of ICMR, India. Hematological, serum biochemical and lung toxicity biomarkers in bronchoalveolar lavage (BAL) fluid were determined. Histopathological analysis of lung tissues and other vital organs was carried out to observe any microscopic changes. Hematology, serum biochemistry and lung toxicity biomarkers in BAL fluid revealed no adverse effects of AKG inhalation except for a slight increase in levels of BAL fluid protein. At autopsy, no histopathological changes in major vital organs, including the lungs were observed. The safety evaluation data suggest that aerosols of submicronic AKG respiratory formulation are safe for inhalation and could be developed as a potential therapeutic option against lung injuries induced through chemical toxicants such as ammonia.Keywords

Objectives: To propose the top books for universities students by using the proposed fuzzy based approach, Ordered Ranked weighted Aggregation method. Methods/Statistical Analysis: The recommendations of books by different universities differ significantly. A staunch aggregation of the differently recommended books by the top ranked universities may lead to vigorous recommendation. We apply Positional Aggregation based Scoring technique, a rank aggregation method for partial list. We have suggested Ordered Ranked Weighted Aggregation (ORWA) operator, which assigns weights to the ranker. Findings: By using proposed technique, the recommendation of top ranked university is preferred over lower ranked universities. The philosophy of ORWA is the fact that the recommendation of a book by a top ranked university will eventually increase the importance of the recommended books. The top 20 books on "Artificial Intelligence" are recommended using PAS and ORWA based techniques. The recommendation would help the users in finding the books of their requirement. Improvements: The relative comparisons between both the discussed techniques PAS and ORWA are discussed and shown graphically. The results indicate a clear improvement of ORWA over PAS.Keywords
