Time domain and time series models for human activity in compensatory tracking experiments, Ph.D. Thesis
Analytical understanding of voluntary human behaviour while performing as an element of a closed-loop manual control situation has been sought since the 1940s. However, a total appreciation of human behaviour has been ... -
Contributions to the development of computationally efficient clustering techniques
The concept of multilevel theory is applied in this thesis to reduce the computation and storage requirements of various existing clustering algorithms. At the first level, the data is divided arbitrarily into a number of ... -
New charactrisations and algorithmic studies on chordal graphs and k-trees
A wealth of literature on graph theory has appeared in the last few centuries. This is to a large extent due to the increase in the applications of graph theory to problems of practical interest. Graph theory is also closely ... -
Kinematics and Rheology of Complex Fluids: Active Suspensions and Dry Granular Materials
This work focuses on two problems in complex fluids, namely collective dynamics of suspensions of self-propelled particles and the rheology of dry granular materials. In both systems, interaction between the particles is ... -
Studies in the computation of thermodynamic properties; v.2
Thermodynamic properties of substances like entropy and enthalpy are important in the study and design of the processes involving liquefaction, solidification, refrigeration, heat transfer, gas separation, and in chemical ... -

Studies on hydrodynamics and liquid-solid contacting in trickle-bed reactors
In trickle-bed reactors, gas and liquid flow concurrently downwards over fixed beds of catalysts. The reactors find wide application for three-phase contacting in chemical, petrochemical, petroleum and fermentation industries, ... -
Studies in heat transfer during condensation of vapours
Till until now surface tension is not taken into consideration. So, the preset work is take up to (1) Collect data on film wise condensation of vapours of organic liquids and aspotropic mixtures. (2) To check the existing ... -
Studies in condensation of vapours
for the same identical conditions, dropwise condensation gives higher heat transfer coefficients compared to filmwise type of condensation. This shows that if dropwise condensation is assured, the condensation surface can ... -
Exploring Single-Chain Collapse Transition in Periodically Grafted Amphiphilic Polymers
Synthetic polymers that emulate the complexity and responsiveness of biological macromolecules are at the forefront of modern materials research. One challenge in this field is to design polymer systems that can fold or ... -
Three Dimensional Boundary Layer with suction and injection
Chapter I deals with the study of incompressible boundary layer over a yawed semi-infinite flat plate with suction or injection by modified Pohlhausen method. IN the first two parts, a comparison of three different velocity ... -
Studies on laminar boundary layer diffusion flames in a confined flow.
When a gaseous fuel is uniformly injected through a porous flat plate into a laminar boundary layer of an oxidant stream, a two-dimensional diffusion flame can be established which exhibits some special features. Despite ... -
Low Reynolds Number Vortex Shedding In Three-dimensional Flows
Understanding of the flow behind the bluff body poses a great challenge and remains almost entirely in the empirical and descriptive realm of knowledge. Flow in the wake of bluff bodies is characterized by the phenomenon ... -
Dynamic behavior of electro-rheological fluid sandwich beams
Electrorheological (ER) fluids are fluids with controllable rheological properties. The study of change in rheology of suspensions due to application of electric field is of interest both from academic and industrial points ... -
Development and critical assessment of a new flic method for base flows
The motivation for the present work stems from two complex base flow problems of relevance to satellite launch vehicles, namely the flow about the base of a rocket body containing an exhaust jet and the aerodynamics of ... -
Reverse transition in a two dimensional boundary layer flow
Experiments on reverse transition were conducted in two-dimensional accelerated incompressible turbulent boundary layers. Mean velocity profiles, longitudinal velocity fluctuations u′u'u′ (i.e., u′2‾\overline{u'^2}u′2), ... -
Inverse transition from turbulent to laminar flow in a two-dimensional channel
An experimental investigation on inverse transition from turbulent to laminar flow in a two-dimensional channel was carried out. The experiments were conducted in the inverse transition region at Reynolds numbers of 525, ... -
Studies on transition from laminar to turbulent flow in a pipe
This thesis describes some investigations on the transition from laminar to turbulent flow in a straight pipe of circu lar cross-section. It is found that Emmons* Theory of transition by the formation and growth of ... -
UAV Group Autonomy In Network Centric Environment
It is a well-recognized fact that unmanned aerial vehicles are considered an essential element in today’s network-centric integrated battlefield environment. Compared to solo UAV missions, deploying multiple unmanned aerial ... -
Synthesis and Self-Assembly Studies of Carbohydrate-Conjugated Oligo-p-Phenylenes
The structural diversity of carbohydrate derivatives is amplified further by their strong tendency to self-assemble in aq. solutions, provided the molecular constitution and environmental conditions favor. Glycostructures ...
