Mitigation of gas and vapour cloud explosions using fine water sprays
Thesis
Johnston, S. Mitigation of gas and vapour cloud explosions using fine water sprays. (Thesis). University of Salford

For the past fifty years or so, there has been a great deal of interest in the use of water based explosion suppression systems, designed to mitigate or reduce the impact of thermal explosions and their consequential overpressures, which may be as hi...

Future spatial audio : Subjective evaluation of 3D surround systems
Thesis
Power, P. Future spatial audio : Subjective evaluation of 3D surround systems. (Thesis). University of Salford

Current surround systems are being developed to include height channels to provide the listener with a 3D listening experience. It is not well understood the impact the height channels will have on the listening experience and aspects associated with...

Efficient and compact representations of head related transfer functions
Thesis
Sinker, J. Efficient and compact representations of head related transfer functions. (Dissertation). University of Salford

These days most reproduced sound is consumed using portable devices and headphones, on which spatial binaural audio can be conveniently presented. One way of converting from conventional loudspeaker formats to binaural format is through the use of He... Read More about Efficient and compact representations of head related transfer functions.

Human response to environmental noise and vibration from freight and passenger railway traffic
Thesis
Sharp, C. Human response to environmental noise and vibration from freight and passenger railway traffic. (Thesis). University of Salford

There is currently a push to increase the proportion of freight traffic that is transported by rail, which is argued to be a safer, more sustainable and more climate friendly means of freight transportation when compared with road or air transportati...

Molecular dynamics simulations in graphite and carbon materials
Thesis
Christie, H. Molecular dynamics simulations in graphite and carbon materials. (Thesis). The University of Salford

Despite having significant applications in the nuclear industry, there have been virtually no molecular dynamics (MD) simulations of radiation damage in graphite. The difficulties in developing an accurate yet computationally inexpensive description... Read More about Molecular dynamics simulations in graphite and carbon materials.

Structural and dynamic investigations of graphite based materials
Thesis
Bailey, A. Structural and dynamic investigations of graphite based materials. (Thesis). University of Salford

Graphite based materials are of particular interest as energy materials. Graphite is used as a moderator in nuclear reactors and there have been investigations into the ability of modified graphites, such as expanded or intercalated graphite, to stor...
