Relational database systems have successfully solved many
business data processing problems. The primary reason of this
success is that the relational data model provides a simple, yet
flexible view of data as tables. In studying VLSI/CAD data, we noticed
that they are often represented in formats similar to relational
tuples....
The processor allocation in an n-dimensional hypercube multiprocessor using buddy strategy, gray code strategy, and a new strategy is implemented on Macintosh. Our implementations show that when processor relinquishment is not considered (i.e. static allocation), all these strategies are optimal in the sense that each incoming request sequence is always...
Structure Query Language (SQL) is widely used to access data stored in relational database systems. Although a powerful and flexible language, SQL can also be complex and hard to learn. For most new SQL users, it's easy to write SQL statement by following SQL grammar and syntax rules, but it's...
The Vehicle Preventative Maintenance System (VPMS) is a 4GL application system that keep track of information required for vehicle maintenance. It can be used to schedule routine vehicle maintenance, and to produce complete and accurate vehicle cost reports, enabling its users to optimize vehicle maintenance. In this report, after describing...
In this report., we address the issues of translating MATLAB scripts into SPMD-style C programs. The resulting programs, when linked with our run-time library are suitable for execution on parallel computers. We describe the design of the compiler and improvements made to it in the current version. We also describe...
This report addresses the design and implementation of an internet-based grading tool for the "Translators" course. The motivation is to avoid exposing the instructor's Java byte-code to possible reverse-engineering tools and enable students to submit their homework virtually from any machine across the internet. This tool is intended to replace...
This report presents a graphical tool for implementation of the scheduling heuristics provided by Kruatrachue. The input of scheduling is a task graph and the output is a schedule in the form of a Gantt chart. The implemented scheduling heuristics are: 1) Hu's HLF (highest level first) algorithm. 2) Yu's...
High Performance Computing can find ubiquitous applications in the industry. HPC-applications are specifically designed to take advantage of the parallel nature of the computing systems which is often enabled by Multi-core/Many-core architectures. With this advent of Multi-processors in the mainstream systems, inter-core communication has been one of the major challenges...
As XML becomes more and more popular, easy-to-use and powerful XML query languages are in great need. Xing is a visual query and restructuring language for XML documents. The objective of this project is to develop a basic version of Xing, including a user-oriented XML query interface and a simple...
Events are an important concept in the Microsoft windows operating system. When a
program runs interactively, it uses a user interface or a console to communicate with the
user. Background services, however, do not have such mechanisms; instead, they use
events to notify the user about changes and to report...
