OTIS (optical transpose interconnection system) is a popular model of optoelectronic parallel computers that has gained enormous attention in the recent years. Several parallel algorithms have been published for many fundamental problems on this architecture. In this paper, first we propose a parallel algorithm for sparse enumeration sort on OTIS-Mesh of Trees (OTIS-MOT). For N (= n2) data elements, our sorting algorithm requires 4 log N$ electronic moves + 3 OTIS moves. We next present a shortest path routing algorithm that runs also in logarithmic time. © 2010 World Scientific Publishing Company. Source

We present two parallel algorithms for finding all the roots of an N-degree polynomial equation on an efficient model of Optoelectronic Transpose Interconnection System (OTIS), called OTIS-2D torus. The parallel algorithms are based on the iterative schemes of Durand-Kerner and Ehrlich methods. We show that the algorithm for the Durand-Kerner method requires (N0.75 + 0.5N0.25 - 1) electronic moves + 2(N0.5 -1) OTIS moves using N processors. The parallel algorithm for Ehrlich method is shown to run in (N0.75 + 0.5N0.25 - 1) electronic moves + 2(N 0.5 - 1) OTIS moves with the same number of processors. The algorithms have lower AT cost than the algorithms presented in Jana (Parallel Comput 32:301-312, 2006). The scalability of the algorithms is also discussed. © 2009 Springer Science+Business Media, LLC. Source

This article reviews and discusses the problems, responses, and concerns of orphans and vulnerable children in India. The article shows that HIV/AIDS programs and interventions are vital for survival and welfare of orphan and vulnerable children, but they have reached only to a small fraction of the most vulnerable children. The article suggests a number of measures that government and civil society could take to address the problems and emphasizes the need to learn from other countries' experience and initiatives in developing appropriate policy and programmes for orphan and vulnerable children.

Incredible escalation of Information Technology leads to generation, storage and transfer of enormous information. Easy and round the clock access of data has been made possible by virtue of world wide web. The high capacity storage devices and communication links facilitates the archiving of information in the form of multimedia. This type of information comprises of images in majority and is growing in number by leaps and bounds. But the usefulness of this information will be at stake if maximum information is not retrieved in minimum time. The huge database of information comprising of multiple number of image data is diversified mix in nature. Proper Classification of Image data based on their content is highly applicable in these databases to form limited number of major categories. The novel ternary block truncation coding (Ternary BTC) is proposed in the paper, also the comparison of Binary block truncation coding (Binary BTC) and Ternary Block Truncation Coding is done for image classification. Here two image databases are considered for experimentation. The proposed ternary BTC is found to be better than Binary BTC for image classification as indicated by higher average success rate. © 2013 Springer-Verlag Berlin Heidelberg. Source

AIM: To present the epidemiology of brucellosis and to assess and suggest public health intervention strategies to control brucellosis in rural India.METHODS: The paper is based on a review of various serological and other studies and evidence on brucellosis in India.RESULTS: Brucellosis is present in all livestock systems. Although the true incidence for human brucellosis is not available, various state specific studies and extrapolated incidence (321 cases annually) have shown that it is a serious disease present in the population. The studies also show that there is a conducive condition and environment for wide-spread human infection on account of unhygienic conditions and poverty in rural areas which need public health attention and intervention.CONCLUSION: The paper suggests that brucellosis needs to be included in public health education and public awareness programmes, particularly in the rural areas of India. It also suggests promoting safe livestock practices, active co-operation between health and veterinary services and a paradigm shift from the current 'biomedical model' to a 'sociocultural model' for the elimination of brucellosis in India.
