Haptic-Based Dental Procedure Training Simulator, Cristian Luciano

Link Foundation Modeling, Simulation and Training Fellowship Reports

Since the beginning of the last century, simulators have been widely used in military and aviation. Recently, the use of simulation in medicine and dentistry has brought the attention of the research community, looking for efficient ways to increase patient's safety by improving surgeon's and dentist's skills. Traditionally, plastic mannequins and cadavers were used to train medical and dental students. However, the lack of details and differences on material properties (in the case of mannequins), and high costs and ethical issues (in the case of cadavers)- supported by the lately improvements of virtual reality, haptics and robotics - have increased …

Advances In In-Situ Calibration Of Attitude And Doppler Sensors For Precision Oceanographic Submersible Navigation, James C. Kinsey

Link Foundation Ocean Engineering and Instrumentation Fellowship Reports

This paper reviews the development and experimental evaluation of three techniques for estimating the alignment matrix of Doppler sonars, which are commonly used for precision navigation of oceanographic submersibles, employing sensors commonly employed aboard these vehicles. Most previously reported methods addressed the problem of single degree of freedom alignment using bottom-lock Doppler sonar data and global positioning system (GPS) navigation data. This paper reviews three techniques for three degree of freedom calibration of attitude and Doppler sonar sensors, using sensor data available to vehicles at full ocean depth. The first technique provides a general linear least-square estimate of the alignment …

Pre-Computation Approach To Nonlinear Simulations Of Deformable Objects, Jernej Barbic

Link Foundation Modeling, Simulation and Training Fellowship Reports

My research area involves building real-time interactive simulations of solid deformable objects. For example, liver tissue should defo1m realistically during a vi1tual surgery simulation. A virtual assembly simulation can catch airplane construction design flaws early on during the manufacturing process. Deformable objects are also useful in computer games, for example to model the motion of trees in the wind. Researchers in computational physics, mechanics, and applied mathematics have been developing algorithms for simulations of deformable objects for the past 40 years. However, the partial differential equations of solid continuum mechanics that govern deformations of physical objects are very involved and …

Creating Geo-Specific Road Databases For A Real-Time Interactive Driving Simulator, Dahai Guo

Link Foundation Modeling, Simulation and Training Fellowship Reports

Geo-specific road database development is important to a driving simulation system and a very labor intensive process. Road databases for driving simulation need high resolution and accuracy. Even though commercial software is available on the market, a lot of manual work still has to be done when the road crosssectional profile is not uniform. This research deals with geo-specific road databases development, especially for roads with non-uniform cross sections. In this research, the United States Geographical Survey (USGS) road information is used with aerial photos to accurately extract road boundaries, using image segmentation and data compression techniques. Image segmentation plays …

Performance Enhancement Of The Wirewalker Wave-Powered Profiler, Jonathan Pompa

Link Foundation Ocean Engineering and Instrumentation Fellowship Reports

The Wire-Walker is a wave-powered vertical profiler made for carrying oceanographic instruments. It cycles continuously through the depth range set by the user, providing a traveling platform for sensors. To achieve high data resolution in time varying environments, the Wire-Walker was redesigned from its original configuration for higher profiling speed. Improvements were made to the WireWalker profiler by using a numerical simulation of the system dynamics. Each physical parameter was varied in the model to find its effect on the profiling speed. Using the guidelines from the modeling experiment, a new WireWalker was constructed and tested in the ocean. The …

Regionalisation And Singapore's Transborder Industrialisation: A New Perspective On Suzhou Industrial Park, Xun Cai, Lu Gao, Caroline Yeoh

Research Collection Lee Kong Chian School Of Business

The dynamics of international economic competition have prompted governments to re-examine accustomed policies, and search for alternative strategies, in order to re-position their economies for the future. This paper takes a look at Singapore’s search for a competitive positioning in the global marketplace, and focuses on the city-state’s much-publicized, and controversial, flagship project in China, viz, the Suzhou Industrial Park (SIP). This strategic initiative is premised on the perceptions that Singapore’s positive reputation with multinational corporations, and ‘guanxi’ (or connections) with regional governments, will give the regional sites a strategic advantage in the competition for foreign investments. Earlier studies have …

Attitudes Toward A Presumed Consent Organ Donation System, Lisa Chan, Justin Cottrell, Pamela Denny-Griffith, Debra Roth, Nora Stephany

Loma Linda University Research Reports

Purpose: Obtaining consent for post-mortem organ donation is a complicated process, and the current system for obtaining consent has not been very effective in procuring sufficient transplantable organs for the current demand. A streamlined method of organ procurement, such as presumed consent, is needed to simplify this process and increase the number of available organs for donation. The purpose of this descriptive study was to evaluate the public's attitudes toward a presumed consent system of organ donation. Methods: A convenience sample of275 adults, aged 18 years or older, was recruited from public establishments in California. Subjects were required to understand, …

Facing China: Taiwan’S Status As A Separate Customs Territory In The World Trade Organization, Pasha L. Hsieh

Research Collection Yong Pung How School Of Law

On Nov 11, 2001, in Doha, Qatar, the Fourth Ministerial Conference of the World Trade Organization (WTO) unanimously approved Taiwan's application for WTO membership, just 24 hours after approving China's admission. Taiwan's choice as the Separate Customs Territory of Taiwan, Penghu, Kinmen and Matsu, abbreviated as Chinese Taipei, in the WTO, instead of its official name, Republic of China (PRC), shows its reluctant compromise with political reality. The PRC's claim that accession procedures applying to Taiwan and Hong Kong should be identical erroneous because, under international trade law, the ROC is the automatic government acting on behalf of Taiwan and …

Spatial Bioaccumulation Modeling In A Network Of Bayous, Ronaldo Luna, Karen H. Watanabe, Andrew J. Wilding

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A software system, Spatial Network Bioaccumulation Model (SNBM), was developed to model the bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) in aquatic food webs. The SNBM uses a geographic information system as an engine to: (i) store the spatial representation of input parameters (the data related to the ecosystem), (ii) transfer input and output data to and from the food-web bioaccumulation model, and (iii) display the predicted food-web organism concentrations over a base map of the field site. The bioaccumulation model is a time-dependent, set of first-order ordinary differential equations that are solved numerically. Many sampling locations can be analyzed using …

Applying Scenario-Based Design And Claim Analysis To The Design Of A Digital Library Of Geography Examination Resources, Yin-Leng Theng, Dion Hoe-Lian Goh, Ee Peng Lim, Zehua Liu, Ming Yin, Natalie Lee-San Pang, Patricia Bao-Bao Wong

Research Collection School Of Computing and Information Systems

This paper describes the application of Carroll’s scenario-based design and claims analysis as a means of refinement to the initial design of a digital library of geographical resources (GeogDL) to prepare Singapore students to take a national examination in geography. GeogDL is built on top of G-Portal, a digital library providing services over geospatial and georeferenced Web content. Beyond improving the initial design of GeogDL, a main contribution of the paper is making explicit the use of Carroll’s strong theory-based but undercapitalized scenario-based design and claims analysis that inspired recommendations for the refinement of GeogDL. The paper concludes with an …

A Multi-Agent Approach For Solving Optimization Problems Involving Expensive Resources, Hoong Chuin Lau, H. Wang

Research Collection School Of Computing and Information Systems

In this paper, we propose a multi-agent approach for solving a class of optimization problems involving expensive resources, where monolithic local search schemes perform miserably. More specifically, we study the class of bin-packing problems. Under our proposed Fine-Grained Agent System scheme, rational agents work both collaboratively and selfishly based on local search and mimic physics-motivated systems. We apply our approach to a generalization of bin-packing - the Inventory Routing Problem with Time Windows - which is an important logistics problem, and demonstrate the efficiency and effectiveness of our approach.

Emi Specifics Of Synchronous Dc-Dc Buck Converters, Zhe Li, David Pommerenke

Electrical and Computer Engineering Faculty Research & Creative Works

DC-DC buck converter topology is widely used in computers and telecom applications because of its high power efficiency and multiple DC levels. However, EMI can be an issue because of its fast switching characteristics and large currents. This paper addresses the analysis of radiated EMI problems associated with DC-DC buck converters and evaluates the effectiveness of solutions that minimize the reverse recovery of the drain-bulk diode of the synchronous switching MOSFET.

A Comparison Of Pso And Backpropagation For Training Rbf Neural Networks For Identification Of A Power System With Statcom, Salman Mohagheghi, Ganesh K. Venayagamoorthy, Yamille Del Valle, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

Backpropagation algorithm is the most commonly used algorithm for training artificial neural networks. While being a straightforward procedure, it suffers from extensive computations, relatively slow convergence speed and possible divergence for certain conditions. The efficiency of this method as the training algorithm of a radial basis function neural network (RBFN) is compared with that of particle swarm optimization, for neural network based identification of a small power system with a static compensator. The comparison of the two methods is based on the convergence speed and robustness of each method.

Analytical Model For The Rectangular Power-Ground Structure Including Radiation Loss, Ji Chen, Todd H. Hubing, Weimin Shi, R. L. Chen

Electrical and Computer Engineering Faculty Research & Creative Works

An accurate analytical model to predict via coupling within rectangular power-return plane structures is developed. Loss mechanisms, including radiation loss, dielectric loss, and conductor loss, are considered in this model. The radiation loss is incorporated into a complex propagating wavenumber as an artificial loss mechanism. The quality factors associated with three loss mechanisms are calculated and compared. The effects of radiation loss on input impedances and reflection coefficients are investigated for both high-dielectric-loss and low-dielectric-loss printed circuit boards. Measurements are performed to validate the effectiveness of this model.
