Anthropomorphic surgical system for soft tissue robot-assisted surgery (2016)
Thesis

Over the past century, abdominal surgery has seen a rapid transition from open procedures to less invasive methods such as laparoscopy and robot-assisted minimally invasive surgery (R-A MIS). These procedures have significantly decreased blood loss,... Read More about Anthropomorphic surgical system for soft tissue robot-assisted surgery.

Safe and effective physical human-robot interaction: Approaches to variable compliance via soft joints and soft grippers (2015)
Thesis

The work described in this thesis focusses on designing and building two novel physical devices in a robotic arm structure. The arm is intended for human-robot interaction in the domestic assistive robotics area. The first device aims at helping to e...

Characterisation and description of compressible rubbery materials for component modelling (2015)
Thesis

Rubbery foams and similar highly compressible rubbery solids form an important class of materials for technology. In order for components made from such materials to be modelled, in Finite Element Analysis (FEA) for example, appropriate constitutive...

Diakoptic assessment of power system voltage variations and applications in weak grids introduced by wind energy – The Nigerian power system in perspective (2015)
Thesis

The electrical power system is a large interconnected system made up of electrical components to generate, transport and utilize electrical power. The size and complexity of the power system have increased significantly in recent years due to the int...

The preparation and characterisation of auxetic foams for the application of trauma attenuating backings (2015)
Thesis

Blunt body trauma, due to a heavy impact or blow, has the potential to cause catastrophic injury in a broad range of professions and workplace environments. At particular risk are those who work in areas such as the military, the engineering and cons...

Innovative optical non-contact measurement of respiratory function using photometric stereo (2015)
Thesis

Pulmonary functional testing is very common and widely used in today's clinical environment for testing lung function. The contact based nature of a Spirometer can cause breathing awareness that alters the breathing pattern, affects the amount of air...

Failure analysis and avoidance for elastomeric diaphragms at high temperatures and pressures (2014)
Thesis

Elastomeric diaphragms are used in the Smart Stabilizer/Weatherford rotary steerable systems (RSS) used in directional drilling down hole. The diaphragms need to operate correctly for the RSS to function effectively. The diaphragm separates the mecha...

Flexible time and ether in one-dimensional cellular automata (2013)
Thesis

A one-dimensional cellular automaton is an infinite row of identical machines---the cells---which depend for their behaviour only on the states of their direct neighbours. This thesis introduces a new way to think about one-dimensional cellular au... Read More about Flexible time and ether in one-dimensional cellular automata.

Integrated capacitated lot sizing and scheduling problems in a flexible flow line (2013)
Thesis

The lot sizing and scheduling problem in a Flexible Flow Line (FFL) has extensive real-world applications in many industries. An FFL consists of several production stages in series with parallel machines at each stage. The decisions to be taken are t...

An engineering method for modeling the interaction of circular bodies and very low aspect ratio cruciform wings at supersonic speeds (2013)
Thesis

An engineering method using a 2D unsteady potential formulation (called the free vortex model or FVM) has been developed to predict the normal force, centre-of-pressure and vortex position for cruciform wing-body combinations in the “plus” orientatio...
