Fault-Tolerant scheduling for scientific workflows in cloud environments

Executing clustered tasks has proven to be an efficient method to improve the computation of Scientific Workflows (SWf) on clouds. However, clustered tasks has a higher probability of suffering from failures than a single task. Therefore, fault tolerance in cloud computing is extremely essential while running large-scale scientific applications. In this paper, a new heuristic called Cluster based Heterogeneous Earliest Finish Time (CHEFT) algorithm to enhance the scheduling and fault tolerance mechanism for SWf in highly distributed cloud environments is proposed. To mitigate the failure of clustered tasks, this algorithm uses idle-Time of the provisioned resources to resubmit failed clustered tasks for successful execution of SWf. Experimental results show that the proposed algorithm have convincing impact on the SWf executions and also drastically reduce the resource waste compared to existing task replication techniques. A trace based simulation of five real SWf shows that this algorithm is able to sustain unexpected task failures with minimal cost and makespan. © 2017 IEEE

Assessment of Diara land under Bhagalpur district using remote sensing and GIS tools

The Diara land is found in between the natural levees of the river and formed due to its meandering and course changing behavior. The topography of Diara land is mostly undulating and intersected with numerous dead and disconnected channels, Remote sensing and Geographical Information System (GIS) is a reliable technique to prepare a comprehensive inventory of land use pattern of an area. The present study was carried out to prepare a complete digital map of diara land of Bhagalpur district using spatial software (TNT Mips). On the basis of visual interpretation of the satellite image and physiographic pattern of the land escape, polygons were digitized for area delineation and mapping for diara land. Out of sixteen blocks of Bhagalpur district, only six blocks were identified as an old Diara land (203.26 km2) and thirteen blocks were identified as a new diara land (869.78 km2). Occupied areas viz. Narayanpur, Bihpur, Kharik, Naugachhiya, Ismailpur, Rangra Chowk and Gopalpur blocks were identified under complete diara land. No any one Diara land characteristics ware marked in Shahkund, Goradih and Sanhaula blocks

Fission in Rapidly Rotating Nuclei

We study the effect of rotation in fission of the atomic nucleus256Fm using an independent-particle shell modelwith the mean field represented by a deformed Woods-Saxon potential and the shapes defined through the Cassinian oval parametrization. The variations of barrier height with increasing angular momentum, appearance of double hump in fission path are analysed. Our calculations explain the appearance of double hump in fission path of 256Fm nucleus. The second minimum vanishes with increase in angular momentum which hints that the fission barrier disappears at large spin

Study of pulmonary tuberculosis in diabetes mellitus

Background: To study the clinical profile of pulmonary tuberculosis in diabetic patients and to study the radiographic patterns of pulmonary tuberculosis in diabetic patients.Methods: The study was undertaken on 100 patients with diabetes mellitus and pulmonary tuberculosis of both sexes admitted to Chalmeda Anand Rao Institute of Medical Sciences, Bommakal, Karimnagar.Results: The fasting blood sugar value showed a definite co-relation with pulmonary tuberculosis. 41% of the patients had fasting blood sugar value between 201 to 300mg/dl and 30% had value between 151-200mg/dl and 23% of the patients had value above 300mg/dl. Mean fasting blood sugar value was 234.4mg/dl. Right sided lung lesions were noted in 37% of the cases and left sided lesions in 33% of the cases. Upper lobe lesions were noted in 68% of the cases and bilateral lesion in 30% of the study group.Conclusions: Uncontrolled diabetes mellitus patients are more prone to develop pulmonary tuberculosis compared to non diabetics. Sputum examination tends to be positive in diabetics compared to non diabetics

Comparison of diagnostic accuracy of APRI and Transient Elastography for prediction of esophageal variceal bleed in liver cirrhosis

Background: Liver Cirrhosis is the end-stage for chronic liver disease. Repeated course of endoscopy is recommended, as this intervention is expensive and often poorly accepted by patients, there is a need for non-invasive methods to predicts the progression of portal hypertension as well as the presence and size of esophageal varices. This study was aimed to assess the APRI and Transient Elastography for predicting esophageal variceal bleed in cirrhotic patients. Objectives of the study were to study Diagnostic accuracy of APRI for Prediction of esophageal variceal bleed in liver cirrhosis, diagnostic accuracy of Transient Elastography for Prediction of esophageal variceal bleed in liver cirrhosis, comparison of diagnostic accuracy of APRI and Transient Elastography for Prediction of esophageal variceal bleed in liver cirrhosis. Methods: It was a Single centre, observational study in 35 patients of chronic liver disease. Patients were included in the study after fulfilling inclusion and exclusion criteria. CBC, LFT, KFT, SE, viral marker, USG whole abdomen, UGIE, Transient Elastography was done. APRI was calculated for every patient. Results: The APRI and Transient Elastography showed moderate diagnostic accuracy in predicting the presence of esophageal variceal bleed. Transient Elastography performed better for prediction of esophageal variceal bleed. Conclusions: The APRI and Transient Elastography showed moderate diagnostic accuracy in predicting the presence of esophageal variceal bleed. They help in starting prophylactic therapy earlier to prevent the bleeding and other complications of varices. These non-invasive parameters can also play an effective role in conjunction with endoscopy in predicting the presence of esophageal varices

Marine fish landings in Gujarat during 2016 - An overview

The district-wise fish production of Gujarat for the year 2016 showed that the Gir-Somnath ranked first (3.42 lakh t), followed by Porbandar (1.13 lakh t), Amreli (0.91 lakh t), Dev Bhoomi Dwaraka (0.85 lakh t), Junagadh (0.72 lakh t), Kutch (0.35 lakh t), Valsad (0.25 lakh t), Navsari (0.08 lakh t), Jamnagar (0.03 lakh t), Morbi (261 t) and Baruch (181 t). The Gir-Somnath district with major fish landings centers like Veraval, Sutrapada, Nawabander, Muldwaaka and Dhamlej contributes significantly to the total marine fish landings in the state. Jaffrabad a major dolnet fish landing center in Amreli district, contributes important fishery resources like nonpenaeid and penaeid prawns, bombayduck, ribbonfish and catfish

Prospective scenario of e-waste recycling in India

However, India is rich in ores and mineral, but E-waste recycling is necessary due to the report of national and international studies, which cautioned on the generation, treatment and accumulation of e-waste in India. Current data indicate that the total domestic e-waste generation including imports is around 382979 MT, however waste available for recycling and actually recycled are 144143 MT and 19000 MT, respectively. In which recycling by non-formal and formal sector are 95% and 5%, respectively. On the other hand, India has developed expertise in handling verities of metallic wastes in an organized and safe man-ner. The development of individual process or combined pro-cesses for handling the e-waste is underway. Eco - friendly and energy-saving processes are necessary to comply with stringent environmental regulations.The paper includes the recent trend of e-waste generation, recycling process and its future prospects particularly in India. prospects particularly in India
