The problem addressed in this paper is that of usability of the Petri Net Editor used to create applications in the Objex framework. This editor puts a lot of burden on the user, in that the user needs to remember all the GUI resources previously created for the application, has...
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 major obstacle to widespread parallel programming of multiprocessors is the lack of a convenient parallel programming system. PPSE (Parallel Programming Support Environment) is a unified approach to parallel programming. Parallax is developed as a component of PPSE based on ELGDF which is a graphical language for designing parallel programs....

In order to make WEPP, which is a Windows-based application, easily accessible, Web WEPP (Web-based WEPP) was developed by our research group.
Web WEPP...
Authentication is a means of developing an electronic signature that works like a written signature. It assumes that your data is publicly known but nevertheless ensures that the message is not tampered with and that you have an audit trail.
This project discusses the techniques and concepts used to design...
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...
We have developed a prototype web-based GIS application for tracking the locations of moving entities. This application, which is called the Responder application, consists of two parts: the Responder client and the Responder server. The Responder client is a .NET application written in C#. It reads the location data from...
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...
Component based software technologies are viewed as essential for creating the software systems of the future. However, the use of externally provided component has serious drawbacks for a wide range of software engineering activities often because of a lack of information about the components. One such drawback involves validation of...

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...
The Soil Conditioning Index (SCI) aids the conservationist in designing crop rotations and residue management practices when low organic matter, poor soil tilt, and crusting problems are identified. The Natural Resources and Conservation Services (NRCS) field staff and others use the SCI as a qualitative tool during conservation planning. In...
Data structures are essential for any programming task. Most of modem programming languages have a library of reusable data structures. In this project, Smalltalk-like collection classes have been implemented as a Java package. This package, collections, contains several useful data structures such as binary tree, B-Tree, bag, list, hash table...
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...
Little Smalltalk is a small, reasonably fast, easy-to-understand, easy-to-modify Smalltalk system. The system was originally developed in 1984 as a part of an implementation project to develop a minimal Smalltalk system, closely resembling Smalltalk-80. The system was developed in C. The current project is an experiment to port the Little...
In this paper we outline an implementation of Linda on a network of Unix workstations. A literature survey was done to gain a better perspective on state of the art and to learn from the experiences of other implementations. The tuple space which is central to the Linda system is...
A remote job control system for the DRAFT machine is developed. It provides the user a convenient remote computing environment with facilities for job submission, a means of servicing the job queue on a first-come-first-serve basis, and usage reporting. It provides a logging facility to keep track of the user's...
RF-based signal identification and classification has received growing attention during recent years due to its potential use in many application domains. Of particular interest is Automatic Modulation Classification (AMC), which has been useful in addressing various spectrum related challenges such as signal jamming, policy enforcement, and spectrum sharing. Adopting AMC...
High Performance Computing can find ubiquitous applications in the industry.

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...
