A New Mathematical Framework for Regional Frequency Analysis of Floods
(2018-06-19)Reliable estimates of design flood quantiles are often necessary at sparsely gauged/ungauged target locations in river basins for various applications in water resources engineering. Development of effective methods for ... -
New Mechanical Methods to Join Sheets in Lap and Butt Configuration and Analytical Model to Predict and Improve Clinching Joint Strength
Mechanical joining of sheets has many advantages over other joining methods in terms of wide variety combination of similar, dissimilar and non-metallic material sheet joining. In conventional SPR joining, the rivet and ... -
New parameterization of atmospheric heating for simple models of relelvance to ENSO
The El Niño Southern Oscillation (ENSO) phenomenon, which is one of the strongest signals of interannual variability in the tropics, arises out of strong interactions between the tropical ocean and the atmosphere. ... -
NEW PERSPECTIVES FOR ANALYZING THE BREAKUP, ENVIRONMENT, EVOLUTION, COLLISION RISK AND REENTRY OF SPACE DEBRIS OBJECTS
(Indian Institute of Science, 2005-03-10)In the space surrounding the earth there are two major regions where orbital debris causes concern. They are the Low Earth Orbits (LEO) up to about 2000 km, and Geosynchronous Orbits (GEO) at an altitude of around 36000 ... -

A Non Resonant Piezoelectric Sensor for Mass, Force and Stiffness Measurements
(2018-09-04)The word piezo in greek means \to compress". Piezoelectric sensors work on the principle of direct piezoelectric effect, where a mechanical input generates a corresponding electric charge. The advantages of these sensors ... -
Non-catalytic synthesis of biodiesel and solubilities of mixtures of lipid derivatives in supercritical fluids
The fossil fuels are depleting rapidly as the demand for energy and its allied chemicals is continuously increasing in the modern world. In addition, the concerns over climate change due to the greenhouse gases emitting ... -
Non-catalytic Synthesis of Biolubricant Esters and their Solubilities in Supercritical Fluids
Breakdown products released due to increased loss of mineral oil based lubricants to the environment lead to aquatic toxicity and release of harmful volatile compounds into the atmosphere. The production of these conventional ... -
A non-classical continuum approach to study the fragmentation of brittle solids
In this thesis, a non-local continuum approach coupled with the phase-field theory and Jones-Wilkins-Lee (JWL) equation of state (EOS) is proposed to model and simulate blast-induced fracture in brittle materials. Also, ... -
