Formulation Of Invariants For Discrete Orthogonal Moments And Image Classification / Pee Chih Yang, Chih Yang Pee Jan 2013

Formulation Of Invariants For Discrete Orthogonal Moments And Image Classification / Pee Chih Yang, Chih Yang Pee

Student Works (2010-2019)

The aim of this thesis is to study invariant algorithms for the domain of discrete orthogonal moments. The invariants are anisotropic scale and translation invariants, translation, rotation and scale invariants, and affine moment invariants. Due to the complexity of hypergeometric functions, existing invariant algorithms are slow. In addition, some of the features have poor classification performance and are highly sensitive to the noise. Therefore new sets of invariant algorithms have been proposed to resolve the above mentioned issues. Discrete Tchebichef moments are selected as the implementation platform of the proposed algorithms.To evaluate the performance of invariant algorithms, empirical studies have …

Negotiating Successfully In Asia, Michael Benoliel

Research Collection Lee Kong Chian School Of Business

Cross-cultural negotiations are complex, challenging, and difficult to navigate because much of the Asian culture is unstated, implicit, and internalized in subtle behavioral patterns. It is like an iceberg; more is invisible and less is visible. To understand how the Asian negotiation values and practices are different from those in the West, I describe briefly the Asian cultural roots, highlight the major dimensions that differentiate cultures, explore the factors that influence the Asian negotiation processes and outcomes, and provide a list of practical suggestions for negotiating successful deals with Asian negotiators.

Endothelial Protective Activity Of Boldine In Animal Models Of Hypertension And Diabetes Mellitus / Lau Yeh Siang, Yeh Siang Lau

Student Works (2010-2019)

Free radical-induced oxidative stress is involved in the pathogenesis of a number of human diseases such as diabetes mellitus, hypertension and atherosclerosis. Endothelial dysfunction, usually assessed as decreased endothelium-dependent vasodilation, precedes clinically before obvious vascular pathologies and together with oxidative stress are major predictors of disease progression. Such endothelial dysfunction is observed early in the development of the pathology and is due, at least in part, to an excessive vascular formation of reactive oxygen species (ROS) in particular superoxide anion (O2−), which reduce nitric oxide (NO) bioavailability. Epidemiological and clinical studies have demonstrated that a growing list of natural products, …
