Students in these programs are required to take a compulsory capstone design project course in their final year of studies. The objective of the design project is to have the students go through the exercise of integrating their knowledge acquired in prior courses and experience gained in cooperative work terms, in a design focused project that satisfies multiple criteria. The issues and problems associated with the design project course are discussed. Past, present, and future initiatives to improve the learning experience and outcome are presented. Focuses of this work are on design content in engineering curriculum, design project team interaction, and design project management.

For applications such as sport instruction, the central issue is to capture motions accurately and correctly for further processing. A Web-based tennis instruction system is under investigation and being designed and developed. To capture the motion of a tennis swing, the Nintendo Wii Remote is used as the input device. The current focus of the project is the various issues associated with motion-sensing input data: capturing, cleansing, classification and clustering of some basic tennis swings, and the subsequent swing matching and identification which can then be used to index into a multimedia database for instructional purpose. In this work, classification of a tennis swing using event-based matching is presented and illustrated with examples. Results from experiments with 50 people are analyzed. The accuracy and the suitability of the matching algorithms are evaluated and discussed.

This system is capable of recommending learning content of potential interest to a user and also the likely Web-browsing action on the current item using a novel similarity measure approach. The recommender is adaptive to individual

Two simple and fast algorithms are proposed, namely, direct algorithm AUCTION and iterative algorithm GREEDYCYCLE. In

Stack dependency is resolved by the use of a hardware bytecode folding algorithm coupled with Tomasulo's scheduling algorithm. In this paper, we present a framework for adapting Tomasulo's algorithm for bytecode folding based Java processors. We discuss a set of architectural features that are tailored for Java execution as well as for general-purpose Java-independent codes. A comprehensive example is included to illustrate these features graphically.

Retrospective study. Major regional hospital, Hong Kong. Clinical records of patients with the diagnosis of achalasia from July 1997 to June 2007 were reviewed. Thirty-two patients were diagnosed with achalasia during the study period. The mean age at diagnosis was 50 years (standard deviation, 20 years). The female-to-male ratio was 1.3:1. The main presenting symptoms were dysphagia (78%) and vomiting (50%). Nine laparoscopic and two open Heller's operations had been performed and 16 patients had undergone endoscopic dilatations. Four patients had botulinum toxin injection and four were taking calcium channel blocker (nifedipine) medications. Botulinum toxin injection and medical therapy had poor short- and long-term responses. Laparoscopic myotomy and pneumatic dilatation had comparable good short- and long-term responses. Achalasia affected all age-groups but there was a p...

Diagnosis of amoebic colitis was confirmed by histological examination of endoscopic biopsy. Doctors treating patients with amoebic infection should be aware of the risk of eradication failure. Post-treatment stool testing, preferably by antigen testing or polymerase chain reaction, should be performed after antimicrobial treatment.

Retrospective descriptive study. Acute public hospital, Hong Kong. Patients with non-malignant liver nodules confirmed by imaging-guided liver biopsy between January 1997 and December 2008. Rates of hepatocellular carcinoma development and survival. A total of 147 patients with non-malignant liver nodules were followed up over a median duration of 29 months. The initial histological diagnosis included regenerative nodules (n=74), low-grade dysplastic nodules (n=34), and high-grade dysplastic nodules (n=39). The respective cumulative hepatocellular carcinoma development rate during the first, second, third, and fourth year were 3%, 5%, 9% and 12% for simple regenerative nodules, 29%, 35%, 38% and 44% for low-grade dysplastic nodules, and 38%, 41%, 51% and 51% for high-grade dysplastic nodules. The hepatocellular ...

Retrospective study. Regional hospital, Hong Kong. Patients with Crohn's disease diagnosed between January 1991 and December 2006 inclusive. Over the period studied, 27 Chinese patients were diagnosed with Crohn's disease in our hospital. Our hospital-based incidence and prevalence rate had increased more than 2- and 5-fold, respectively over that period. The mean age at diagnosis was 26 years and median duration of disease was 81 months. Most patients had ileocolonic disease (67%) followed by Crohn's colitis (22%) and ileal disease (11%); more patients had non-stricturing and non-penetrating disease (63%) than stricturing (15%) or penetrating disease (22%). Peri-anal disease occurred in 37% of our patients. At diagnosis, many of the patients (41%) had mild-moderate disease, but 30% each had moderate-severe and severe-fulminant disease. At the time of this study, 85% of the p...
