A Grid Enabled E-Theses And Dissertations Repository System, Maizatul Akmar Ismail

Maizatul Akmar Ismail

Some of the universities in Malaysia are still implementing hybrid Electronic Theses and Dissertations (ETD) approach in managing Theses and Dissertations (TD). One of the limitations of the hybrid ETD approach is its online cataloguing method, which is only available at the physical location of the TD instead of enabling the information to be retrieved online. Maintaining the performance and the data accessing rate of an ETD system has become challenging, due in part to the high number of scholars who utilise and access the system. In order to allow remote access and maintain the services such as scalability, accessibility, …

Enhancement In The Photocatalytic Activity Of Au@Tio2 Nanocomposites By Pretreatment Of Tio2 With Uv Light, Mohammad Mansoob Khan Dr, M. H. Cho Dr

Dr. Mohammad Mansoob Khan

A novel, efficient and controlled protocol for the synthesis and enhanced photocatalytic activity of Au@TiO2 nanocomposite is developed. TiO2 (P25) was pretreated by employing UV light (λ = 254 nm) and the pretreated TiO2 was uniformly decorated by gold nanoparticles (AuNPs) in presence of sodium citrate and UV light. UV pretreatment makes the TiO2 activated, as electrons were accumulated within the TiO2 in the conduction band. These accumulated electrons facilitate the formation of AuNPs which were of very small size (2-5 nm), similar morphology and uniformly deposited at TiO2 surface. It leads to formation of stable and crystalline Au@TiO2 nanocomposites. …

Resampling-Based Information Criteria For Best-Subset Regression, Philip T. Reiss, Lei Huang, Joseph E. Cavanaugh, Amy Krain Roy

Philip T. Reiss

When a linear model is chosen by searching for the best subset among a set of candidate predictors, a fixed penalty such as that imposed by the Akaike information criterion may penalize model complexity inadequately, leading to biased model selection. We study resampling-based information criteria that aim to overcome this problem through improved estimation of the effective model dimension. The first proposed approach builds upon previous work on bootstrap-based model selection. We then propose a more novel approach based on cross-validation. Simulations and analyses of a functional neuroimaging data set illustrate the strong performance of our resampling-based methods, which are …

Estimation Of Copula Models With Discrete Margins Via Bayesian Data Augmentation, Michael S. Smith, Mohamad A. Khaled

Michael Stanley Smith

Estimation of copula models with discrete margins is known to be difficult beyond the bivariate case. We show how this can be achieved by augmenting the likelihood with latent variables, and computing inference using the resulting augmented posterior. To evaluate this we propose two efficient Markov chain Monte Carlo sampling schemes. One generates the latent variables as a block using a Metropolis-Hasting step with a proposal that is close to its target distribution, the other generates them one at a time. Our method applies to all parametric copulas where the conditional copula functions can be evaluated, not just elliptical copulas …
