This paper focuses on the use of code features for automatic plagiarism detection. Instead of the text-based analyses employed by current plagiarism detectors, we propose a system that is based on properties of assignments that course instructors use to judge the similarity of two submissions. This system uses neural network techniques to create a(More)
have developed an integrated software package for the analysis of real-time radar, satellite, and numerical weather prediction model data, known as the Warning Decision Support System – Integrated Information, hereafter " WDSS-II " (Smith et. al. 2003, Stumpf et. al. 2003) The NOAA Storm Prediction Center (SPC) is in the process of implementing the WDSS-II(More)
We describe an extension of the virtual volume concept to multiple sensors. Data from multiple sensors are combined in real-time and mapped into a constantly updating three-dimensional grid. The data are combined in a time-centric manner, with data replacing older data, regardless of the sensor that the older data came from. We discuss scaling problems with(More)

2009 File systems are tasked with storing, organizing, and retrieving valuable data for long periods of time. This requires them to provide excellent fault-tolerance and reliability standards throughout their extended lifetime. As a result, most file systems follow a conservative development model and evolve slowly. In comparison, the underlying storage(More)
We present a consistent means of accessing, in real-time or play-back, data from disparate sources. The data are geographically and temporally referenced, and placed in one of several source-independent in-memory formats depending on the type of data. We describe how to implement this referencing, and how to take advantage of the referencing and common(More)
We describe the requirements – scientific, technical and economic – of scientists and engineers who are developing new meteorological algorithms and products. We argue that these requirements call for quick and ready access to multiple, disparate sources of data (including the outputs of other algorithms) in a uniform manner. We also argue that developer(More)
