Rotationally Invariant Kinetic Upwind Method (KUMARI)
(2009-03-11)In the quest for a high fidelity numerical scheme for CFD it is necessary to satisfy demands on accuracy, conservation, positivity and upwinding. Recently the requirement of rotational invariance has been added to this ... -
Satellite Attitude Determination from Terrestrial/Planetary Landmarks
Attitude Determination (AD) or specifying orientation relative to a known reference frame plays a crucial role in meeting the mission specific pointing goals of a satellite. Attitude sensors provide measurements of known ... -
Satellite derived chlorophyll a distribution in the Bay of Bengal during northeast monsoon
The Bay of Bengal is a semi-enclosed tropical ocean basin driven by the monsoon winds. The Bay receives a large quantity of freshwater from river discharges and rainfall, which leads to very low salinity values in the ... -
Scaling Characteristics Of Tropical Rainfall
(2016-11-15)We study the space-time characteristics of global tropical rainfall. The data used is from the Tropical Rainfall Measuring Mission (TRMM) and spans the years 2000-2009. Using anomaly fields constructed by removing a single ... -

Seasonal and Intraseasonal Variation of Tropical Climate in NCAR CCM2 General Circulation Model : Sensitivity to Cumulus and Surface Processes
In this thesis, we have undertaken a detailed study of the role of surface processes and the effect of changes in cumulus parameterization on the simulation of tropical climate by the CCM2 model of NCAR. We have examined ... -
Seasonal cycle of the hydrography and circulation of the Bay of benga
The Bay of Bengal is the smaller of the two semi-enclosed basins of the North Indian Ocean. Due to the impact of monsoons, the Bay exhibits strong seasonal changes in the circulation and in salinity of its surface layer. ... -
The Seasonal ENSO Transition Mode of the Southern Hemisphere: Definition, Characteristics and Impact
Decadal climate variability (DCV) exerts a profound influence on the global climate system by shaping background oceanic and atmospheric conditions. It drives long-term changes in sea surface temperatures (SSTs), monsoon ... -
Seasonal Isotopic Variability and Major Ion Chemistry of the Cauvery River Basin, Peninsular India
Surface water and groundwater interactions are inherently complex because they occur across a range of spatial and temporal scales. This thesis envisages to improve our understanding of surface water and groundwater in ... -
Seasonal variation of the zonally symmetric tropical circulation in a simple climate ,model
A low-order model of the zonally symmetric tropical circulation is developed. The model equations are linearized about a resting basic state and are solved on an equatorial beta-plane. The circulation is forced by the solar ... -
Secondary Atomization of a Droplet in Diverse Interaction Settings
Secondary atomisation refers to the process by which liquid droplets, which are already in a dispersed state, are further atomised down into smaller droplets. This process occurs after primary atomisation, which is the ... -
Sedimentation Of Heavy Particles In Turbulence
(2010-08-06)Behavior of particles in buoyancy driven turbulent flow at Ra ≈ 10º is investigated experimentally. The volume fraction of the particles is low enough for the inter particle influence to be neglected, the mass loading ... -
Seepage Effects on Stream Power, Resistance, Incipient Motion and Regime of Sand Bed Channels including Its Design
(2018-07-28)Common behavioral trends and characteristics of alluvial channels including rivers are extensively discussed in the literature. However, little is known about the hydrodynamic effects of seepage on alluvial channels. Factors ... -
Seismic evaluation of 3D tunnels in near fault ground motion using domain reduction method
Underground tunnels are an essential part of transportation and utility networks, and their vulnerability to earthquakes has significant socio-economic impacts. Tunnels have suffered substantial damage in past earthquakes, ... -

(2018-02-10)Tee present research focuses on seismic hazard studies for the states of Tripura and Mizoram in the North-East India with taking into account the complex sesismotectonic characteristics of the region. This area is more ... -
Seismic Microzonation Of Lucknow Based On Region Specific GMPE's And Geotechnical Field Studies
(2016-09-09)Mankind is facing the problem due to earthquake hazard since prehistoric times. Many of the developed and developing countries are under constant threats from earthquakes hazards. Theories of plate tectonics and engineering ... -
Seismic response of Geocell Retaining walls
Use of tensile reinforcement for improving the seismic stability of retaining walls has gained considerable attention in recent times and has become a very common practice. Compared to planar geosynthetic materials, geocells ...
