A Comparative Study On Optimal Structural Dynamics Using Wavelet Functions
A Comparative Study On Optimal Structural Dynamics Using Wavelet Functions
Faculty of Engineering University of Malaya
Wavelet solution techniques have become the focus of interest among researchers in different disciplines of science and technology. In this paper, implementation of two different wavelet basis functions has been comparatively considered for dynamic analysis of structures. For this aim, computational technique is developed by using free scale of simple Haar wavelet, initially. Later, complex and continuous Chebyshev wavelet basis functions are presented to improve the time history analysis of structures. Free-scaled Chebyshev coefficient matrix and operation of integration are derived to directly approximate displacements of the corresponding system. In addition, stability of responses has been investigated for the proposed …
An Accelerated And Accurate Three-Dimensional Ray Tracing Using Red-Black Tree With Facet Mining And Object Bouncing Techniques
Faculty of Engineering University of Malaya
Recent trends show that it is a major challenge to predict the exact propagation path accurately and efficiently for three-dimensional (3D) indoor environments. Therefore, this study introduces a new 3D ray tracing algorithm based on a red-black tree with facet mining and object bouncing techniques. The red-black tree data structure offers a faster object searching operation while repeatedly performing intersection tests. On the other hand, extensive ray-facet intersection tests can be eliminated by using object and facet bouncing techniques, whereas the facet mining makes it easier to trace the transmitted ray paths accurately. The proposed method is compared with ray …

Modern Rail Innovation In Japan, Sakdirat Kaewunruen
Sakdirat Kaewunruen
This presentation was invited by Engineers Australia to discuss the importance of railway experience in Japan. Abstract: Rail transport has become one of the most desirable and environmental-friendly means for mass transportation, especially when the up-and-coming peak oil crisis has threatened and discredited many other modes of transport (including traditional car vehicles, trucks, and air planes) from being economical, efficient and sustainable. In this presentation, the modern rail systems in Japan, which cover metro, local and high speed rails, will be discussed together with the infrastructure development, network strategy, ticketing and sources of revenues. Because Japan is the pioneer of …
