Correlations between charged particles in deep inelastic e+ p scattering have been studied in the Breit frame with the ZEUS detector at HERA using an integrated luminosity of 6.4pb-1. Short-range correlations are analysed in terms of the angular separation between current-region particles within a cone centred around the virtual photon axis. Long-range correlations between the current and target regions have also been measured. The data support predictions for the scaling behaviour of the angular correlations at high Q2 and for anti-correlations between the current and target regions over a large range in Q2 and in the Bjorken scaling variable x. …

Measurement Of High-Q2 Charged-Current E+P Deep Inelastic Scattering Cross Sections At Hera, J. Breitweg, S. Chekanov, M. Derrick, D. Krakauer, S. Magill, B. Musgrave, A. Pellegrino, J. Repond, R.

The e+p charged-current deep inelastic scattering cross sections, dσ/dQ2 for Q2 between 200 and 60000 GeV2, and dσ/dx and dσ/dy for Q2 > 200 GeV2, have been measured with the ZEUS detector at HERA. A data sample of 47.7 pb-1, collected at a center-of-mass energy of 300 GeV, has been used. The double-differential cross-section dσ/dQ2 falls by a factor of about 50000 as Q2 increases from 280 to 30000 GeV2. The double differential cross section d2σ/dxdQ2 has also been measured. A comparison between the data and Standard Model (SM) predictions shows that contributions from antiquarks (ū and c̄) and quarks (d …

Managing The Acidity Of Abandoned Water Filled Coal Mining Voids In Collie (Western Australia) Using Organic Matter, Scott A. Thompson Jan 2000

Managing The Acidity Of Abandoned Water Filled Coal Mining Voids In Collie (Western Australia) Using Organic Matter, Scott A. Thompson

Theses: Doctorates and Masters

The effectiveness of using organic matter additions to increase pH in abandoned water filled coal mining voids in Collie was investigated. Previous studies have demonstrated that passing acidic drainage through organic matter increased the waters pH. Laboratory trials using intact sediment cores (collected from Ewington, Collie, Western Australia) were used to assess the effects of additions of hay, manure and mulched vegetation on pH, nutrients an sulphate levels. In a series of experiments the effect of different quantities of organic material, sulphate reducing bacterial inoculations and alkalinity generation were measured. A subsequent field experiment was conducted to examine the impact …

An Investigation Of The Relationship Between Organisational Size And Industry Type With The Development And Use Of Executive Information Systems In The Manufacturing Sector, Nigel Warne Jan 2000

An Investigation Of The Relationship Between Organisational Size And Industry Type With The Development And Use Of Executive Information Systems In The Manufacturing Sector, Nigel Warne

Theses: Doctorates and Masters

The purpose of this investigative research is to provide quantitative detail to better understand the development and use of Executive Information Sysytems (EIS) in the Australian Manufacturing sector. This investigation is an extension of previous research done on EIS in Australia (Prevan, 1992; Pervan and Phua, 1997) and looks more closely at the independent variables of organisation size and industry type in their relationaship with the development and use of EIS. A broad literature review provides a descriptive model that gives some insight into the development and use of EIS over more than fifteen years. Over eighty per cent of …

Quality Of Service Management For Non-Guaranteed Networks, Tarek Madkour Jan 2000

Quality Of Service Management For Non-Guaranteed Networks, Tarek Madkour

Archived Theses and Dissertations

The increasing dominance of multimedia communication posed new requirements for the underlying systems. Multimedia data, formally called continuous media, has time constraints that impose real time limitations for their transmission. Certain levels of service, called Quality of Service (QoS), need to be considered when handling continuous media. The present work utilizes QoS concepts for networks that do not have inherent QoS support. The thesis aims at verifying the possibility of having QoS-controlled communication on non-guaranteed networks. A basic QoS architecture is designed where already existing QoS concepts are adapted to work with non-guaranteed networks. The architecture provides the facilities of …
