India is a developing country and the citizens of India are dreaming that within 2020, India will become a well-developed nation. Indian government has started Start-up India, Make in India to improve our nation, but still women in India are facing lots of obstacle towards their improvement. Despite this, women are having high exposure and they are working in all fields like defense, engineering,...
This work presents chip-scale integration of MEMS resonant mass balances along with aerosol inertial impactors (airborne micro/nanoparticle collectors). A three mask microfabrication process has been developed to produce the main components; mass balance, impactor nozzle, and impaction micro-chamber on a single SOI substrate. In addition to extreme miniaturization of a conventionally bulky setup and...
A generic framework for estimating the reliability of equipment is through “information fusion” of its failure history, predictive maintenance data and domain expert's knowledge is proposed and demonstrated. The framework uses “Degree of Certainty” arrived at using fuzzy sets and “Belief” & “Plausibility” measures to arrive at a decision on the effectiveness of predictive maintenance. Uncertainty,...
Equipment Health Monitoring through Predictive Maintenance (PDM) data is proposed and the same is demonstrated with case study. Steel Rolling Mill Gearbox is considered for the purpose. Empirical failure rate model using Equipment Health Index (EHI) is proposed and used it for forecasting maintenance requirements of the process equipment. The strength of the proposed approach lies in integrating multiple...
Process plants like integrated steel plants use thousands of electric motors as prime movers of process equipment. The reliability of motors, especially large motors in the range of several hundreds of kilowatt capacity is vital as breakdown of these motors leads to breakdown of major facilities which these drive and cause large production losses. The maintenance of these large motors is often planned...
Nanosatellite is the prime focus of many universities those who are interested in space technology. Nanosatellite is popular due to its feasibility and affordability. The primary mission of the Sathyabama nanosatellite is pollution monitoring and data communication to the earth station. For any satellite, On Board Computer (OBC) is considered to be the brain of the satellite. OBC must be designed...
The monitoring of landscape changes can lead to the identification of environmental hot spots, improve process understanding, and provide means for law enforcement. Digital elevation models (DEMs) derived from stereoscopic satellite data provide a systematic synoptic framework that is potentially useful to support these issues. Along-track high-resolution stereoscopic data, provided with rational...
