Random Vibration of limit cycle systems and stochastic strings.
The behaviour of the Van der Pol oscillator under periodic excitation is well known. The effect of adding noise to the excitation has been studied in this chapter. Three different solutions are obtained based on the Gaussian ... -
The analysis of unreinforced brick masonry Vaults
There has been a revival of interest in unreinforced brick masonry vaults in recent years. The present thesis deals with studies on smallspan brick masonry vaults with a view to developing an understanding of their structural ... -
Finite Difference Modelling of Seepage and ground water flows
The thesis presents several studies in finitedifference modelling of seepage and groundwater flow. After presenting a literature review on the available methods for finitedifference models in groundwater flow, the scope ... -
Erosion by Liquid jet Impingement on Aluminium using plain and cavijets
The impact of materials by liquids occurs under various conditions and is common in a variety of engineering equipment such as hydroturbines, pumps, steam turbine blades, diesel engine liners, spillway gates, ship propellers, ... -
Analysis of volume change behaviour of partly saturated soils.
Classical geotechnical engineering principles have evolved mainly in regions dominated by temperate climates. Over the last few decades, engineering and construction needs have expanded into less familiar areas such as the ... -
Variations in boundary shear stress in sand bed channels subjected to seepage
Field channels are invariably subjected to seepage across the perimeter of their cross sections. Therefore, it is necessary that the effect of seepage be understood clearly, as it may form an important factor to account ... -
Plastic analysis of plates subjected to multiple loads
A simple analysis for the determination of the carrying capacities of the axisymmetric plate under combined loading has been presented in this chapter. Some brief remarks are appropriate on the interpretation to be given ... -
Strength behaviour including stress-strain relations of clays-
Stability problems for their analysis and design necessitate an assessment of appropriate strength parameters of a given soil system. In soil masses, since deformations result largely from slippages between soil particles, ... -
Elastic stress analysis of circular cylinders
When two cylinders of different elastic properties are joined together and the compound cylinder thus formed is subjected to external loading, the stresses at and in the neighborhood of the joint or the interface get ... -
Influences of foundation elasticity on the vibration and buckling characteristics of arches
The effect of foundation deformation has been studied in detail with reference to the buckling of elastically supported and uniformly compressed inextensible circular arches. The numerical results obtained indicate that ... -
Some studies on the ultimate load capacity of arches and arch dams
The behaviour of a plain concrete rectangular section under an eccentric thrust, up to failure, may be studied using an appropriate strain pattern and a suitable stress-strain curve for concrete. The curve obtained using ... -
Studies in the elastic stress analysis of hollow circular cylinders
From the investigations on the analysis of hollow cylinders subjected to axisymmetric boundary conditions reported in the previous five chapters, the following conclusions are summarized: 1) In Chapter 1, an exact solution ... -
Some studies on new types of venturimeters
This thesis presents the details of the investigations on some new types of Venturimeters designed and tested at the Hydraulics Laboratories of the Indian Institute of Science, Bangalore. Chapter I Chapter I gives an ... -
Some studies on the hydraulic jump
An air concentration probe has been developed which is ideally suited for measurements in a jump. Complete air concentration studies of the jump have been made for nine Froude numbers from 2.42 to 11.72. It has been ... -
Systems-level modelling of hepatitis C virus Infection and treatment response
Hepatitis C Virus (HCV) infection affects approximately 130-170 million people worldwide. Interferon-based treatment, the current standard of care, fails to cure a significant fraction of patients. The cause of this treatment ... -
Testing the hypothesis of quorum sensing in vibrio fischeri : luminescence, motility, and biofilm
The individual behavior of prokaryotic organisms such as bacteria often gives rise to complexity typically associated with multicellular systems. The transition from unicellular to multicellular behavior occurs in response ... -
Dynamo action due to turbulence in a linear shear flow
Astrophysical systems such as the Sun, disc galaxies, galaxy clusters, and accretion discs possess ordered magnetic fields alongside random components. These magnetic fields survive for timescales much longer than diffusion ... -
GMRES acceleration of kinetic flux vector split (KFVS) Eulercodes
The present work is concerned with the acceleration of Euler codes using the Generalized Minimal Residual (GMRES) algorithm. The codes taken up for acceleration are 2D cellcentred, timemarching, finitevolume explicit Euler ...
