WAVE TRAPPING BARRIERS. Traditional noise barriers have poor performance when installed as parallel barriers in front of noise sources with large reflection surfaces. This is because that the reflected noise from the far side barrier or from the source surfaces contributes significantly to the noise level at the receiver location. This project involves the investigation of a novel barrier, the wave trapping barrier (WTB), which is capable of retaining the noise between the source and the barrier ....WAVE TRAPPING BARRIERS. Traditional noise barriers have poor performance when installed as parallel barriers in front of noise sources with large reflection surfaces. This is because that the reflected noise from the far side barrier or from the source surfaces contributes significantly to the noise level at the receiver location. This project involves the investigation of a novel barrier, the wave trapping barrier (WTB), which is capable of retaining the noise between the source and the barrier and to provide maximum sound absorption at the frequencies of concern, and thus to minimize the contribution due to the reflection. The aim is to develop a theoretical and experimental model for the physical understanding and optimal design of the WTB. Outcomes include a new generation of noise barriers that are potentially light-weighted, fiberless and with higher insertion loss.Read moreRead less

Model-Reduction Techniques for Control, Communication and Circuits. Model reduction is an important area of study in the analysis and design of dynamical systems. Its objective is to obtain a low-order model given a high-order system model such that the low-order model closely approximates the input-output behaviour of the original high-order system. Although theory and application of model reduction is well developed, there are many unresolved issues such as efficient model reduction techniq ....Model-Reduction Techniques for Control, Communication and Circuits. Model reduction is an important area of study in the analysis and design of dynamical systems. Its objective is to obtain a low-order model given a high-order system model such that the low-order model closely approximates the input-output behaviour of the original high-order system. Although theory and application of model reduction is well developed, there are many unresolved issues such as efficient model reduction techniques for large-scale circuit simulation and communication applications, frequency-weighted model reduction techniques for controller-design applications, and error bounds for the reduction techniques. The project aims to address these issues.Read moreRead less
