Wavelength division multiplexed arrays of in-fibre Bragg gratings (IFBGs)
are fabricated in hydrogen loaded optical fibres. The IFBG arrays are embedded into a
carbon fibre composite test beam for the purpose of quantitative ...
Many computational problems of theoretical and practical
interest are not naturally bounded by physical boundaries.
Aerodynamic examples include flow calculations past aerofoils or past
wing-body configurations, ...
This thesis describes both experimental and theoretical work performed
in order to analyse fatigue fracture in the presence of shot-peening
induced residual stresses.
In the study, four contrasting alloys were examined ...
This work dealt with elasto-plastic analysis of 2-dimensional and
axisymmetric problems using the finite-element and boundary-element
techniques. The analysis is based upon a vide range of yield
criteria and hardening ...
The orifice meter is still commonly used for natural gas measurement despite its
many limitations. Considerable efforts in recent years have resulted in improved
knowledge of factors such as installation effects and the ...
Carneiro, Helder Fernando De Franca Mendes(1993-05)
An Attempt at development of theory and computer program for the solution of
potential and viscous flow problems using the Boundary Element Methods is
introduced in this work. A program for potential flow analysis of ...
Mechanical seals are used extensively on rotary applications where the sealed fluid is under pressure. They may rightly be considered to be generally reliable and trouble free, many giving lives of over 3 years. However, ...
Fracture and toughening mechanisms in rubber modified and hybridized urethane-methacrylate
resins have been investigated. Fracture mechanisms are defect-dominated in the unmodified
resin. The relationships between defect ...
The influence of process parameters on deposition and fusion
characteristics of mild steel with Pulsed Gas Metal Arc Welding has
been investigated using a transistorized power supply.
A simple model of melting behaviour ...
The dispersion of air into water was studied in a tall agitated vessel (ungassed liquid
depth = 2.4 x vessel diameter) fitted with four different triple impeller combinations:
1. Three identical Rushton turbines
2. One ...
This thesis is a description of an experimental study of gas-liquid
dispersion in mechanically agitated vessels. The objectives of the
project were to investigate scale-up and to compare different
agitator types. Three ...
Heat pipe heat exchangers (HPHEs) offer many advantages over other types of
heat exchangers for the recovery of heat from industrial gaseous waste streams in
the low and medium temperature ranges. Heat pipes employed in ...
This research has been concerned with the oxidation
and corrosion of iron and mild steels, with particular
reference to the importance of the mechanical properties
of the surface oxides formed. A vibration technique ...
The basic properties of arcs in flowing ga-,es, minimum
ignition energy and quenching distances are the\focal points of this
research. The flow parameters turbulence, pressure, velocities, fuel-air ratio etc. are varied ...
A portable and compact demodulation system was constructed and calibrated. It was
found that the best performance could be achieved using the peak detection algorithm
written in a LabView™ program. A resolution of ...
Three dimensional complex flows particularly those of turbomachinery present
challenges to current measurement technology in terms of restricted optical access,
measurement accuracy for the on-axis velocity component, ...
This thesis reports the results of a detailed programme of
research on airblast atomization carried out using a specially
designed plain-jet atomizer in which the fuel is injected into
a high velocity airstream in the ...
During the anaerobic corrosion of steel, hydrogen sulphide
(H2S) evolution by the Sulphate-Reducing Bacteria (SRB)
promotes hydrogen absorption by enhancing cathodic hydrogen
evolution and inhibiting the combination of ...
Systems development has been a topic of discussion for many years, with the growth of the Information Technology (IT) industry. Many organisations use systems to allow them to have more control over the processes that are ...
A Kalman filter is used to integrate the outputs from a
Global Positioning System and an Inertial Reference System
inside a Flight Management Computer.
To initialise the Kalman filter, account is taken of the 1RS
errors ...
