Title: Kwong Hing Investment (HK) Ltd project - design & implementation of the execution unit of a pipelining object-oriented descriptor computer targeting on JAVA Authors: Yu, Wing Shing Abstract: JAVA is a famous Object-Oriented programming (OOP) language and becoming popular in the industry. High Level Instruction Set Computer (HISC) is a new architecture to give hardware support on the OOP like JAVA. It extends the features of typical descriptor computer architecture and applies the object-oriented programming concept in hardware level. A 64-bit architecture machine calls Object-Oriented Descriptor Computer is designing which use the HISC computer architecture to enhance the running Java. Execution unit is the heart of a processor. Instruction is passed into and specified operation will be performed. The Execution unit of the Object-Oriented Descriptor Computer is to perform operation on primitive types of JAVA and support the OOP features in hardware level. In this project, we will discuss the design and implementation of the execution unit of a pipelining Object-Oriented Descriptor Computer target on JAVA programming. It is implemented with Xilinx Virtex XCV 800-6 FPGAs on a Nallatech Ballynuey Virtex PCI card. The aims of the project are providing the support of the operation on the primitive types on JAVA effectively and evaluate the performance and functionality with FPGA.

Title: Astec: enhance a quality database Authors: Yau, Kam Fai Abstract: In today’s business environment, most of the companies that were currently under development afford some types of data access. As increasing numbers of developers adopted the client/server model as the basis for their applications, the choice of servers and the architecture of servers became much more important to the overall success of enterprise-wide computing. In addition, as more businesses depend increasingly on technology to bring users and information together, to streamline processes, and to decentralize decision-making, distributed client/server computing provided the necessary connection between data and informed business decisions. In order to assemble and analyze the information from different areas, database should be built. A database was a collection of information organized in such a way that a computer program can quickly select desired pieces of data. We can think of a database as an electronic filing system, or a phone book. Moreover, a computer database can be put up on the World Wide Web for data retrieval.

Title: Medical information retrieval and indexing Authors: Wong, Li Tung Abstract: Dr. Chan K L. Assessor: Mr. Cheng L L; This project aims to develop an information system for the storage and communication of medical data. The system is intended to be used by doctors or the authorized hospital or clinical staff. The data involved are textual patient records, electrocardiograms, etc. Different retrieval schemes have been developed to handle different types of data. For the text record system, the database has been used to store the information. The retrieval of patient record can rely on query such as sex, record ID, weight, height, blood type or disease. Then the system will show the records that match the query. The users can view the record in detail. Also the users can easily add and retrieve patient record via the user-friendly interface. Hence, doctors can refer to the retrieved records in diagnosis. On the other hand, the system provides storage and retrieval functions for electrocardiogram (ECG) files. They include ECG file display, QRS complex detection, and ECG retrieval. The ECG file display shows the waveform of the MIT/BIH arrhythmia ECG file. The QRS detection can locate all the QRS positions of an ECG waveform. The system can extract individual heart beat cycles from the ECG waveform. Users can select and add the heart beat cycles to the database for future reference. ECG retrieval allows the search of heart beat cycles in the database, which mostly match to the query, based on the morphology of the characteristic ECG waves. Finally, this system can support different operating modes, such as the standalone and also client-server models. Hence, the users can retrieve the medical information at a remote terminal.

Title: Animated talking head Authors: Wong, Cheung Tat Abstract: This project aims to build a 3D animated talking head, which base on English, and the interface to control the 3D head. That means user can control the 3D head to talk with the speech given. After input the sound file and the text, a movie of the 3D talking head with the input can be produced. And the 3D head is lip synchronized with the speech. It is implement by using powerful 3D Drawing software “MAYA”. The 3D head is built up in MAYA environment and using the deformation function in MAYA to deform the 3D head with different mouth shapes. The user interface and the function for producing the 3D talking head movie is written by MAYA script “MEL”. There is also a C program is used for converting the English text into the corresponding Phoneme. Finally the 3D head and the interface are built up in MAYA. The 3D talking head movie with the speech input can be produced. The accuracy of the lip synchronization and comparability of the mouth shapes is acceptable.
