This study utilized the GIS-based Soil and Water Assessment Tool (SWAT) model to simulate the flow of Vu Gia - Thu Bon river basin at two hydrological stations - Nong Son and Thanh My, during the calibration period (2004 - 2010) and the verification period (2011 - 2015). The evaluation results of both periods, as measured by the NSE and R2 indexes, were found to be above 0.75.

In this thesis, the rolling contact wear of 52100 bearing steel and Over-aged Magnesia-Partially-Stabilised Zirconia (OA-Mg-PSZ) ceramic are examined using a newly developed rolling contact wear test rig. The new wear test rig simulates the system geometry of an un-lubricated hybrid (ceramic and steel) ball bearing. The new wear test rig is versatile in that it allows low cost samples to be utilised resulting in a larger number of samples that can be tested.

This purpose of this work was to investigate the patient radiation doses and image quality of a Philips/Agfa computed radiographic (CR) system and a Philips indirect-capture digital radiographic (DR) system in a paediatric setting. A CDRAD digital radiographic contrast-detail phantom was used to assess radiographic image quality. Perspex slabs of three different thicknesses (6, 11 and 16 cm) were used to simulate paediatric patients of three arbitrary ages.

The main focus of this thesis is on the application of a model predictive control (MPC) method to devise an ABS for a BBW vehicle. Unlike the traditional ABS control algorithms which are based on a trial and error method, the MPC based ABS algorithm aims to utilizes the behaviour of the model to optimize the wheel slip dynamics subject to system constraints. Performance of the proposed wheel slip controller is validated through Software-in-the-Loop (SiL) and Hardware-inthe-Loop (HiL) simulation.

The primary goal of this research is accomplishing the BUUAS that can realize functions in the mission profile. In order to achieve this, the project starts with developing elemental aspects of the BUUAS. The configuration and propulsion system are two basic elements that the BUUAS must have to realize successfully operation. Besides, the necessary transition process between water and air must be investigated and carried by a conceived system.

The objective of this study is to investigate the hotspot (fires and other thermal anomalies) detection and characterization product from the TET-1 satellite sensing system from the German Aerospace Centre (DLR). The satellite is envisioned, as part of a constellation of satellites, to provide detection and characterization of fires at a higher spatial resolution when compared to the current standard global coverage from the MODIS fire products.

This research demonstrates how housing demand can be modelled by using a System Dynamics approach. This modelling concept has been set up, using the root causes which generate housing demand. Causal factors which influence housing demand are collated, and mapped. A model simulating housing demand was developed. Keys to this are demographic, social and economic factors. This model is presented with a view to pursuing new approaches for housing demand modelling.

Modelling the diffusion of mobile commerce in a country is a difficult task due to the non-linear, complex and uncertain nature of its operating environment. Conventional analytical techniques are of limited use in this context, and a System Dynamics approach is more appropriate to model such a complex system.

In particular, the system undergoes three stages. At first stage the relaxation proceeds slowly so that the energy of system slightly decreases and the samples structure remains amorphous. Within second stage a structural transformation occurs which significantly changes PRDF and DCN for the relatively short time. The energy of the system is dropped considerably and the amorphous structure transforms into the crystalline. Finally, the crystalline sample undergoes the slow relaxation which reduces the energy of system and eliminates structural defects in crystal lattices.

Batch-type laboratory reactivity experiments and mo delling of hydrogeochemical interactions of a granite-scCO2-water system were conducted at 100 °C and 10 MPa in order to evaluate the geochemical and mineralogical responses of the granite to long-term reaction. The laboratory reactivity tests were conducted for a to t l duration of 70 days, and the continued hydrogeochemical interactions for up to 210 days we re determined by geochemical simulations.

In this paper we use a new method based on Einstein’s equation to calculate the diffusion coefficient of impurity atoms in the disorder systems. Simulation results show that the diffusion coefficient D obeys the Arrhenius law. The dependence of the diffusion coefficient D on temperature for regular disordered lattice is also examined and discussed.

Using the non-force method we simulate diffusion on a disordered chain consisting of 2000 sites for a wide range of temperature. Three types of disordered chains, site, saddle and site-saddle system are considered. The influence of site and saddle disorders and Arrhenius behavior is also investigated and discussed in this work.
