Using simulations

In this study, the adsorption configuration, adsorption energy of toxic gas molecules (CO, NO, CO2, NH3, and NO2) on B12 – borophene was investigated by first – principle calculations using three van der Waals correlation functionals: RevPBE-vdW, optPBE-vdW, and vdW-DF2.

In the present study, cooling of PV module using a paraffin-based phase change material (PCM) in hot climate of Vietnam is investigated. Thermal modelling is first validated against experimental data reported in literature and then transient thermal simulations are carried out for a duration of 24 hours to assess the effect of PCM itself and PCM with internal fins.

This research aims to numerically simulate the performance of the tested PC utility poles using Applied Element Method (AEM) and Finite Element Method (FEM). The simulation results demonstrate that both AEM and FEM effectively reproduce the load-displacement relationship observed in the test. Additionally, this study discusses the material models employed in simulations, considering the limitations inherent in numerical modeling.

In this laboratory experiment, you will use SPICE to study sinusoidal waves on lossless transmission lines. Our goal is for you to become familiar with the basic behavior of waves reflecting from loads in transmission lines, and compare the simulations with numeric calculations and the Smith Chart.

The modelling of traffic flow using methods and models from physics has a long history. In recent years especially cellular automata models have allowed for large-scale simulations of large traffic networks faster than real time. On the other hand, these systems are interesting for physicists since they allow to observe genuine nonequilibrium effects. Here the current status of cellular automata models for traffic flow is reviewed with special emphasis on nonequilibrium effects (e.g. phase transitions) induced by on- and off-ramps.

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 purpose of the study is to quantify breast dose to reassure patients and staff that these understandings still apply. A combination of measurements and simulations were used to estimate absorbed breast dose. Gafchromic® XR-QA2 film was used to measure breast dose placed inside the RANDO® phantom in a series of controlled experiments. The RANDO® is an anthropomorphic phantom commonly used for dosimetry investigations. Gafchromic® XR QA2 film is a radiochromic film that changes colour when irradiated. Simulation is commonly used and readily available.

The objective of this research was to determine the role of neural feedback and muscle mechanics in the generation of physiological tremor oscillation. This research developed a neuromuscular model to simulate the individual and resulting oscillatory mechanisms of tremor. The oscillations found in EMG signal were also analysed empirically from EMG data from 54 subjects using Hilbert Transform and rectification to obtain the envelope of the signal. The time between rhythmical waveform patterns in the EMG signal, TC was found to be 78ms.

The main objective of this research is to optimize the design of the Tunnel kiln for efficient fuel usage. To achieve that, the temperature distribution from the simulation needs be matched with the desired Tunnel kiln curve found in industry. This objective can be achieved by CFD simulation where temperature, velocity and emission distributions inside the Tunnel kiln can be obtained. Generated temperature distribution can be matched with the industrial curve and by interpreting the curve, efficient design can be suggested.

This thesis proposes and implements a new and novel solution on simulators and real devices to solve the mobility problem in a VPN. The new solution adds mobility support to existing L2TP/IPsec (Layer 2 Tunneling Protocol/IP Security) tunnels. The new solution tunnels Layer 2 packets between VPN clients and a VPN server without using Mobile IP, without incurring tunnel-re-establishment at handoff, without losing packets during handoff, achieves better security than current mobility solutions for VPN, and supports fast handoff in IPv4 networks.

The aim of this research was to investigate the formation of hydrogen sulphide for different sewage characteristics and flow rates. An experimental set-up was developed to simulate a section of a gravity sewer pipe, the set-up comprised of a pipe of 2 m long and 155 mm inside diameter, referred to in this thesis as a laboratory sewer pipe. The first stage of the experimental program involved developing a biological growth rich in sulphate-reducing bacteria inside the laboratory sewer pipe using synthetic sewage.

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.
