Speech Title: Development of functional ceramic coatings using Physical Vapor Deposition systems

Abstract: Several functional ceramic coatings were developed mainly for mechanical and aerospace applications. The used of different Physical Vapor Deposition techniques like electron beam deposition, simultaneous vapour deposition and magnetron sputtering deposition, were utilized to deposit the coatings. The main objective of applying such coatings were to improve the overall mechanical performance of the parts or devices. Finite element method was carried out to ascertain the mechanical behaviour of the coating. Samples were subjected to relevant characterization analysis and physico-chemical tests, particularly to determine the mechanical properties of the coatings. Recently, a newly designed powder based magnetron sputtering system was successfully developed. A lot of exciting experiments were conducted using the system which is able to effectively sputter various type of ceramics, metallic and metallic alloy powders.

Department of Electronic Engineering, City University of Hong Kong, Hong Kong

Speech Title: Polymer Waveguide Optics


Waveguide-based optical devices are finding important applications in optical communications, optical signal processing, and optical sensors. Among the many waveguide materials, polymer possesses a number of distinct advantages. First, it is easy to form and process polymer thin films and low-cost processes, such as imprinting and hot embossing, for mass production of polymer planar lightwave circuits are available. Second, polymer is compatible with practically any optical materials, which makes it possible to form hybrid devices with enhanced performance. Third, the dimensions of polymer waveguides and optical fibers are well matched, which can ease device packaging. Fourth, optical polymer is in general photosensitive, which allows the development of fast and inexpensive laser/UV-writing methods for the fabrication or post-processing of polymer waveguide devices. Fifth, the large thermo-optic coefficient of polymer can be explored to realize effective thermally tunable devices. Last, but not the least, it is easy to form multilayer and hence three-dimensional (3D) waveguide structures with polymer. 3D waveguide optics not only leads to more compact devices, but also provides more flexibility in the device design. This feature of polymer has become particularly useful for the development of mode (de)multiplexers, which are the key components in the emerging mode-division -multiplexing fiber communication technology. The availability of special polymer materials, such as electro-optic polymer, can further widen the scope of applications with optical polymer. While the stability of optical polymer is often questioned, highly stable polymer materials are commercially available. Nowadays, optical polymer waveguides can be embedded in printed circuit boards with a lamination process that involves both high pressure and high temperature. In this talk, the speaker will provide a review of the polymer waveguide technology with some of the devices fabricated in his laboratory as examples.

Speech Title: A preference ranking method  for green supplier selection: A comparative result based on preference functions

Abstract: The PROMETHEE is a significant method for evaluating alternatives with respect to criteria in multi-criteria decision making problems. It is characterised by many types of preference functions that is used for assigning the differences between alternatives in judgements. This paper proposes a preference of green suppliers using the PROMETHEE under the usual criterion preference functions. Comparable results are presented to check the effect of different preference functions to the final preference.  Seven economical and environmental criteria, four suppliers and five decision makers were the main structures in the green supplier selection problem.  Data was collected via personal communication with decision makers using five-point Likert scale. The algorithm of PROMETHEE under usual criterion function was implemented and the results show that supplier A1 is the most preferred alternative. Comparative results also show that  supplier A1 is the most preferred alternative despite the difference in preference functions used.

Speech Title: Do we need to integrate Unmanned Aerial Vehicles into commercial airspace?

Abstract: Currently Unmanned Ariel Vehicles, UAV, are not allowed to fly in commercial airspace as there is a perceived risk of collision. To prevent this likelihood systems could be used to ensure safety and avoidance.  Making UAVs ore complex limits their advantage. and adds considerable costs. This research presentation will address the research topics and engineering aspects that are being reviewed and explored to seek alternative solution by having UAVs fly about commercial airspace. The challenges and successes are presented and highlight how UAVs can be used in long distance flight without the risk for collision.

Speech Title: Physical and Geometric analysis of the transit FRW Universe in Conharmonic Flat Space


General exact solutions of the Einstein’s field equations by using conharmonically flat space with time-dependent cosmological “constant” for a spatially homogeneous and isotropic Friedmann-Robertson-Walker (FRW) model filled with perfect fluid has been obtained. To determine the solution of the field equations, the concept of a time-dependent deceleration parameter is used. This yields a scale factor for which the universe attains a phase transition scenario from early decelerating to present accelerating era and is consistent with recent cosmological observations. We have considered the three cases for best fit models: Case1: By using recent constraints (H0 = 73.8, and q0 = −0.73) from supernovae type Ia union data (Cunha, arXiv:0811.2379 [astro-ph]). Here H0 and q0 are present values of Hubble and deceleration parameters respectively. Case2: By using recent constraints (H0 = 73.8, and q0 = −0.54) from SN Ia data in combination with Baryonic Acoustic Oscillation (BAO) and Cosmic Microwave Background (CMB) observations (Giostri et al., arXiv:1203.3213 [astro-ph.CO]). Case3: By using recent constraints (H0 = 69.2 ± 1.2, and 1549437431337532.png) from recent 36 observational Hubble data (OHD) compiled by Yu et al. (2018) and joint light curve (JLA) dataset. I have compared the cosmological models with these three experimental data. Taking into consideration the observational data, it is observed that the cosmological constant Λ behaves as a positive decreasing function of time and tends to be a constant value at late time. Our derived modes are in good agreement with ΛCDM model. Some physical and geometric analysis of the models are also discussed.

Speech Title: Handling of Multicollinearity and Outliers using Robust Methods For Efficient Prediction

Abstract: Multicollinearity exists when two or more of the predictors in regression model are highly correlated. It results in a wrong sign problem of regression coefficients, causes regression estimates to have unduly large variances.  Since the absence of multicollinearity is often an unrealistic assumption, researchers should consider how the results are affected by multicollinearity. However, many do not realize that high leverage points (HLPs), those observations that fall far from the majority of the explanatory variables are the most harmful observations because they are mainly responsible for misleading conclusion about the fitting of a regression model, causing multicollinearity problems, masking and/or swamping of outliers, etc.  HLPs can change the multicollinearity pattern of a data and they are referred as high leverage collinearity influential observations (HLCIO). The HLCIO can be classified into high leverage collinearity-enhancing (HLCEO) or high leverage collinearity- reducing observations (HLCRO).  By correctly identifying HLCIO, may help statistics practitioners finding the correct remedy to these problems. In this presentation, the diagnostic methods of identifying HLCIO will be discussed.  Proper robust methods are then proposed to rectify the problems of multicollinearity which are caused by HLCEO and HLCRO.  The usefulness of the proposed methods is studied by some well-known data set and Monte Carlo simulation.
