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, ... -
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 ... -
Role Of Sea Surface Temperature Gradient In Intraseasonal Oscillation Of Convection In An Aquaplanet Model
(2016-11-15)In this thesis we examine intra-seasonal oscillations (ISO) in the aqua-planet setup of the Community Atmospheric Model (CAM) version 5.1, mainly based on July and January climatological sea surface temperature (SST). We ... -
Pozzolanic Additives To Control Dispersivity Of Soil
(2016-11-13)The aim of the present investigation is to improve the geotechnical properties of dispersive soil by reducing their dispersivity after elucidating the important mechanisms controlling the dispersivity of the soils. ... -
Design And Analysis Of Flexible Beam Platform As Vibration Isolator For Space Applications
(2016-10-20)Spacecrafts are generally equipped with high precision optical and other sensor payloads. The structures of most of the spacecrafts are light-weight, flexible and have low damping. Vibrations are often induced in the ... -
Dynamics Of Cricket Song Towards Nature-inspired MEMS Speakers
(2016-09-15)The clever designs of natural transducers are a great source of inspiration for man-made systems. At small length scales, there are many transducers in nature that we are now beginning to understand and learn from. Here, ... -
LES Study Of Free Jets And Jets Impinging On Cuboidal Cavity
(2016-09-15)Numerical solutions based on explicit filtered LES for computing turbulent flow field, of free round jets and impinging round jet on cuboidal cavities, are presented and discussed in this dissertation work. One-parameter ... -
Experiments On Rolling Sphere Submerged In An Incompressible Fluid
(2016-09-15)Experiments are done using a smooth solid rigid homogeneous acrylic sphere rolling on an inclined plane which is submerged in water. The motivation for these experiments comes from a need to understand a class of solid-fluid ... -
Development Of An Advanced Methodology For Automotive IC Engine Design Optimization Using A Multi-Physics CAE Approach
(2016-09-14)The internal combustion engine is synonyms with the automobile since its invention in late 19th century. The internal combustion engine today is far more advanced and efficient compared to its early predecessors. An intense ... -
Studies In The Dynamics Of Two And Three Wheeled Vehicles
(2016-09-09)Two and three-wheeled vehicles are being used in increasing numbers in many emerging countries. The dynamics of such vehicles are very different from those of cars and other means of transportation. This thesis deals with ... -
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 ... -
Muscle Fatigue Analysis During Dyanamic Conraction
(2016-09-09)In the field of ergonomics, biomechanics, sports and rehabilitation muscle fatigue is regarded as an important aspect since muscle fatigue is considered to be one of the main reasons for musculoskeletal disorders. Classical ... -
A Computational Platform For Automated Identification Of Building Blocks In Mechanical Design For Enhancing Ideation
(2016-09-09)Conceptual design is an early stage in the design process, in which functional requirements of a design problem are transformed into solution concepts for satisfying the requirements. It is regarded as a crucial step in ... -
