Towards An Assessment Framework Of Reuse: A Knowledge Level Analysis Approach, Ghassan Beydoun, Achim Hoffmann, Rafael Valencia-Garcia, Jun Shen, Asifqumer Gill

Faculty of Engineering and Information Sciences - Papers: Part B

The process of assessing the suitability of reuse of a software component is complex. Indeed, software systems are typically developed as an assembly of existing components. The complexity of the assessment process is due to lack of clarity on how to compare the cost of adaptation of an existing component versus the cost of developing it from scratch. Indeed, often pursuit of reuse can lead to excessive rework and adaptation, or developing suites of components that often get neglected. This paper is an important step towards modelling the complex reuse assessment process. To assess the success factors that can underpin ...

Faculty of Engineering and Information Sciences - Papers: Part B

Ballasted tracks play an essential role in its economy through transporting freight and bulk commodities between major cities and ports, and carrying passengers, particularly in urban areas. Ballast usually consists of hard and strong angular particles, which are derived from high strength unweathered rocks. Ballast aggregates undergo gradual and continuing degradation under cyclic train loadings. In this study, the load-deformation responses of ballasted rail tracks subjected to cyclic loading are studied experimentally using a large-scale Track Process Simulation Apparatus (TPSA), and numerically through a coupled discrete-continuum approach, namely, coupled DEM-FEM. Laboratory tests are carried out to examine the deformation and ...

Faculty of Engineering and Information Sciences - Papers: Part B

It has not been many years since a majority of Bhutanese were cooking with firewood as their fuel source. However, over the years the fuel mix has been changing and depicting increasing share of clean fuel such as electricity (hydropower generation) and liquefied petroleum gas (LPG). Subsequently there is a massive opportunity to switch into modern, clean and efficient cooking technologies such as induction cooktops and reduce the overall fuel/wood consumption. Induction cooktop is a fairly new concept in the country; therefore, users are often sceptical about investing in them due to lack of awareness on the cost-benefit analysis ...

Analysis Of Variability Of Tropical Pacific Sea Surface Temperatures, Georgina Davies, Noel A. Cressie

Faculty of Engineering and Information Sciences - Papers: Part B

Sea surface temperature (SST) in the Pacific Ocean is a key component of many global climate models and the El Niño-Southern Oscillation (ENSO) phenomenon. We shall analyse SST for the period November 1981-December 2014. To study the temporal variability of the ENSO phenomenon, we have selected a subregion of the tropical Pacific Ocean, namely the Niño 3.4 region, as it is thought to be the area where SST anomalies indicate most clearly ENSO's influence on the global atmosphere. SST anomalies, obtained by subtracting the appropriate monthly averages from the data, are the focus of the majority of previous ...
