Fine-Scale Structure Of The Diurnal Cycle Of Global Tropical Rainfall
(2016-11-16)The fine-scale structure of global (30N-30S) tropical rainfall is characterised using 13 years (1998-2010) of 3-hourly and daily, 0.25-degree Tropical Rainfall Measuring Mission (TRMM) 3B42 rainfall product. At the outset, ... -
Finite difference modelling of ground water flows
The thesis presents several studies on finite difference modelling of groundwater flow systems. The studies include: (i) Development of an efficient computational algorithm for nonrectangular flow domains; (ii) Comparative ... -
Finite Element Analysis of Interior and Boundary Control Problems

Finite Element Limit Analysis for Solving Different Axisymmetric Stability Problems in Geomechanics : Formulations and Solutions
(2017-11-15)Limit analysis is a very powerful tool to find accurate solutions of several geotechnical stability problems. This analysis is based on the theory of the plasticity and it provides two limiting solutions within lower and ... -
Finite Element Method based Model Order Reduction for Electromagnetics
Model order reduction (MOR) refers to the process of reducing the size of large scale discrete systems with the goal of capturing their behavior in a small and tractable model known as the reduced order model (ROM). ROMs ... -
Finite Element Modeling of Knee Joint to Study Tibio-Femoral Contact Machanics
(2018-05-10)Articular cartilage covers the articulating ends of diarthrodial joints. It plays a vital role in the function of the musculoskeletal system by allowing almost frictionless motion to occur between the articular surfaces ... -
Finite field computational techniques for exact solution of numerical problems
In this dissertation, we consider the application of residue arithmetic for the exact computation of g-inverses in order to obviate the round-off errors normally associated with their computation. It turns out that for ... -
Finite field transforms applicatons to cryptography and error free polynimial matrix computation
In this dissertation, we have presented the properties of finite field transforms and a few of their applications. We do not consider our study exhaustive, and we expect other applications to be developed soon. The most ... -
