Design Architecture-Based on Web Server and Application Cluster in Cloud Environment

Cloud has been a computational and storage solution for many data centric organizations. The problem today those organizations are facing from the cloud is in data searching in an efficient manner. A framework is required to distribute the work of searching and fetching from thousands of computers. The data in HDFS is scattered and needs lots of time to retrieve. The major idea is to design a web server in the map phase using the jetty web server which will give a fast and efficient way of searching data in MapReduce paradigm. For real time processing on Hadoop, a searchable mechanism is implemented in HDFS by creating a multilevel index in web server with multi-level index keys. The web server uses to handle traffic throughput. By web clustering technology we can improve the application performance. To keep the work down, the load balancer should automatically be able to distribute load to the newly added nodes in the server

Assessment of Response Time for New Multi Level Feedback Queue Scheduler

Response time is one of the characteristics of scheduler, happens to be a prominent attribute of any CPU scheduling algorithm. The proposed New Multi Level Feedback Queue [NMLFQ] Scheduler is compared with dynamic, real time, Dependent Activity Scheduling Algorithm (DASA) and Lockes Best Effort Scheduling Algorithm (LBESA). We abbreviated beneficial result of NMLFQ scheduler in comparison with dynamic best effort schedulers with respect to response time.Comment: 7 pages, 5 figure

PROCESS OPTIMISATION OF PILOT SCALE BIODIESEL PRODUCTION FROM PONGAMIA AND WASTE COOKING OIL FEEDSTOCK

Biodiesel is the most promising renewable alternative fuel for fossil diesel fuel, which can be produced even in rural settings of an economically backward sector of developing countries. Biodiesel can be produced from non-edible seed oils or used edible oil sources by a transesterification reaction. Biodiesel feedstock differ according to geographic location, therefore, it is essential to optimise the biodiesel production process at least in pilot scale for each source to obtain highest biodiesel yield to be used for domestic purpose. In the present study, biodiesel was produced from non-edible Pongamia seed oil and Waste Cooking Oil separately using the 50 L capacity pilot scale reactor. The crucial reaction parameters such as catalyst (NaOH) concentration, alcohol (Methanol) volume and reaction time were optimised through Box-Behnken Design (BBD) approach to maximise the biodiesel yield. In the optimised pilot study, the biodiesel yield of 89.1% from Pongamia oil and 96% from Waste Cooking Oil sources were obtained. Also, the biodiesels produced by pilot scale met the requisite quality standards of ASTM, EU and India

Diarrhea, Pneumonia, and Infectious Disease Mortality in Children Aged 5 to 14 Years in India

Background: Little is known about the causes of death in children in India after age five years. The objective of this study is to provide the first ever direct national and sub-national estimates of infectious disease mortality in Indian children aged 5 to 14 years. Methods: A verbal autopsy based assessment of 3 855 deaths is children aged 5 to 14 years from a nationally representative survey of deaths occurring in 2001–03 in 1?1 million homes in India. Results: Infectious diseases accounted for 58 % of all deaths among children aged 5 to 14 years. About 18 % of deaths were due to diarrheal diseases, 10 % due to pneumonia, 8 % due to central nervous system infections, 4 % due to measles, and 12 % due to other infectious diseases. Nationally, in 2005 about 59 000 and 34 000 children aged 5 to 14 years died from diarrheal diseases and pneumonia, corresponding to mortality of 24?1 and 13?9 per 100 000 respectively. Mortality was nearly 50 % higher in girls than in boys for both diarrheal diseases and pneumonia. Conclusions: Approximately 60 % of all deaths in this age group are due to infectious diseases and nearly half of these deaths are due to diarrheal diseases and pneumonia. Mortality in this age group from infectious diseases, and diarrhea i
