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...
This paper discusses Java Bytecode Obfuscation techniques that make the reverse engineering task more difficult. This paper is structured as follows: Java virtual machine and Java language specifications are discussed first. Then the paper talks about different techniques for protecting software and then details one promising approach named Obfuscation. The...
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...
The WEPP (Water Erosion Prediction Project) application computes soil loss and sediment yield from a field based on the data on crops, management practices, and operations. 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...
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...
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...
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...
Ad Hoc networks are multi-hop wireless networks consisting of mobile hosts. They do not have any pre-existing network infrastructure and are characterized by constantly changing topology, limited battery power and bandwidth. Typical applications of such networks are battlefield networks, medical relief during natural calamities or disasters, conference room networking, and...
The increasing need to share and synchronize personal information, such as schedules, tasks and events, amongst users has lead to the development of inter-personal information management software like ChandlerTM. Chandler is being developed in Python at the Open Source Applications Foundation, San Francisco. Before I started working on the project...
