Parallel A* search on a multi-core CPU

Multi-core central processing units (CPU) and the graphics processing unit (GPU) have become popular parallel computing platforms in recent years [1]. The GPU platform is commonly adopted in the research community as it has been to be superior to the traditional CPU. Straightforward implementations of Parallel algorithms on a GPU can easily achieve a speedup of ten times or more over the sequential algorithms. However, achieving significant speedup on a multi-core CPU (over the sequential algorithm) requires intelligently designed and well-optimized algorithms [3]. This paper discusses a parallel implementation of A* search which achieved 6.67x Speedup with a search space of 106 nodes, 3.14x speedup with 107 nodes, and 137.67x speedup with 108 nodes when run on the eight-core, 3.0 GHz Intel Core i7 processor. This paper also analyses different work partitioning strategies and how the performance of the parallel A* search algorithm scales.

Design of rainwater harvesting system in RRCE campus

Rainwater harvesting system is mainly the process or a phenomenon of collection and conservation of rainwater from various techniques where the rainwater is the main source for the process of harvesting. Here we mainly consider the rooftop rainwater harvesting system for the collection of rainwater from roof or top of the buildings of Rajarajeswari College of Engineering campus. The study and implementation of the technique of rooftop rainwater harvesting system in RRCE campus mainly fulfill the needs and also resolves the issue of scarcity of water in all seasons by equivalent supply of collected and stored water for future needs . Also groundwater recharge could be done in efficient way. By implementation of this technique, water source will be increased up to 1420 meter cube in the campus which also intern could be used for construction works as well as maintenance of the good gardening works in the campus .Thus we can say it mainly fulfill the needs of scarcity of water and also mainly recharge groundwater

Controlling web browser via different hand gestures and speech recognition

Gestures and speech are major forms of human communication. The primary goal of gesture recognition is to create a system that can identify specific human gestures whereas the primary goal of speech recognition is to create a system that can convert speech sound into its corresponding text. In this paper, we have implemented a real-time gesture recognition system where a user can navigate a computer to a particular website by doing a specific gesture in front of a web camera linked to the computer. We have also implemented a speech recognition system that takes speech as an input from the device microphone, converts it into text, and thereafter performs different operations.

A multivariate statistical approach for ranking the best batsmen in test cricket

The primary objective of this paper is to devise a ranking system for individual test batsmen (from different eras) considering all possible factors like the difficulty of opposition bowlers, the batsman’s consistency, the contribution of the batsman in the success of his team, the era in which he played, etc. Due to the presence of such numerous factors—each one of them having a significance of its own, it is imperative that a multivariate statistical approach is employed in the ranking of Test batsmen. A total of eight factors were zeroed in on which were thought to influence the performance of a batsman. An index was developed for each of the eight factors, and thus each of the batsmen got eight different scores for the eight different factors. Consequently, the eight scores of the batsman act as the coordinates of a point/cluster in an eight-dimensional plane. In this way, each of the batsmen under study is represented by a point in an eight-dimensional plane. Finally, to determine the most exceptional batsmen among the batsmen under study, the concept of multivariate statistical outlier detection using Mahalanobis distances was used. However, the concept of Outlier Detection only gives us an idea of the most exceptional batsmen when compared to the others. In order to determine the best batsmen, the process of outlier detection is followed up with the determination of the efficiencies of each of the batsmen under study. The efficiencies of the batsmen are calculated by adopting the approach of Data Envelopment Analysis (DEA), wherein each batsman is likened to a machine or a Decision-Making Unit (DMU). The higher the efficiency of a batsman, the greater his success in converting low inputs (difficult input parameters) to high outputs.

Bio-control of mosquito larvae using filamentous fungi-environmental study

fungal species are useful for medical and agriculture purpose as a bio- control agent. In aquatic environments, temperature, salinity and organic pollution are the important factors.The objective of the current project was to investigate the possibilities of controlling the mosquito population using fungal cultures. to investigate the possibilities of controlling the mosquito population using fungal cultures. In the view of rampant increase in the incidence of dengue fever transmitted through mosquitoes it is absolutely essential to control the mosquito population. There are different species of mosquitoes of which dengue virus is transmitted by the Aedes aegypti, found in habitats like stagnant clear waters, backyards which are common in urban areas. In the present work water samples were collected from in and around Mumbai, the water samples were examined for its nutritional status by analyzing them physically, chemically and biologically.The fungal cultures obtained from water samples were predominantly Aspergillus niger, Aspergillus terreus, and Penicillium, Trichoderma, Curvularia, Sprolegmia and Achlya.. As per the results it was observed that the Curvularia was the most effective on the larvae as the mortality rate was 100%. . The death of the larvae could be possibly due to the organic acids produced by the fungi. Microscopic observation of the larvae shows the growth of the fungi on larvae ultimately killing it. This is the most effective bio-control.
