A Diagnostic Method for the Service Span of Oil - Immersed Transformer with EXCEL Application Software[ ]


For the safety and reliability of operation in power systems, oil-immersed transformer’s service span needs to detect strictly on a regular basis for the purpose of transformer safety diagnosis. On the review of the existing diagnostic approaches of oil-immersed transformer for aging or deterioration of insulation material, the gases of CO, CO2, 2-Furaldehyde, 2-Furfuryl alcohol, 2-Acetyl Furan, 5-methyl-2-furaldehyde, and 5-Hydroxymethyl-2-Furaldehyde, are among the wildly used ones. The concentration of CO2 and CO is been taken from the Dissolved Gas Analysis and the remaining gases taken from the IEC-1198 or ASTM D 5837. The concentration of those gases can inspect from a few of insulating oil out and know how long still leave of the service span of oil-immersed transformer is. The paper focuses on a diagnosis method for the service span of oil - immersed Transformer with EXCEL application software. Finding an accurate, effective and convenient method is motivating by how to improve diagnosis of transformer’s service span. In some cases, the feasibility of the tool has undergone verification. The main advantage of the method is the effective diagnosis of transformer’s service span by a form-reported computer program closely.

Integrating mechanism-based screening paradigm into homology and de novo modeling exemplified by Mycobacterium Tuberculosis 30S ribosomal structure and its potential application as a screening target[ ]


Mycobacterium tuberculosis, the causative agent of the tuberculosis, has infected more than 33% of the total populace to date. It is known to be considerably aggressive and profoundly impervious to current medications that target it. Aminoglycosides, for example, viomycin and capreomycin have been shown to bind to important functional regions of the M tuberculosis ribosome thus its process of protein synthesis is inhibited subsequently affecting the cell viability. Current techniques for studying drug interaction through generation of three-dimensional macromolecular structures are slow and tedious. This study exhibits a more proficient and cheap method for producing structure models in silico by utilizing both de novo and homology modeling strategies.

VIRTUAL REALITY IMPLEMENTATION IN HOME AUTOMATION[ ]


Home Automation is becoming a crucial part in fast growing economies. Recently it's technologies are changing rapidly and different automating strategies are being implemented. The conceptual understanding for automation is changed, and new ways of producing super sensor system are showing up. So basically home automation is “One way to manage everything, not lots of ways to manage lots of things”. In normal Electrical circuit combination in all the Indian houses people tend to do many mistakes while using it. The prime mistakes are not switching off the electrical gadgets when not required or when not in use. People tend to either forget when moving out or ignore. This results in wastage of energy without using it. To eradicate all these drawback it's better to adopt Automation techniques. So here we are aiming to provide a fully automated system which can ensure safety by switching ON and OFF of the electrical devices based on user’s action. The background subtraction methodology is used in extracting the foreground region. The reference image of the background is continuously adjusted to match the foreground image. Thus the touch detection takes place. When we tested our system it proved to be robust to differences in illumination. It resulted in controlling the devices with a minimum response time of 160ms.
