Many of the concepts that need to be taught in software engineering courses are hard to get across because it is difficult to give the student practical experience of the intuitions and techniques involved. The student must come to understand multiple design and implementation formalisms whose relationship is often hidden by modern commercial software. Education theory would suggest that studen...

A major technological concern of our work is to improve the cost effectiveness, reusability, and interoperability of advanced educational software. To make these technologies viable, we must be able to add component functionality incrementally, and enable systems to interoperate with commercial software and internet resources. We have designing and implemented an architecture that places shared...

Large-scale screening of small organic compounds has become a standard and essential practice in the early discovery of chemical entities with potential therapeutic use. To effectively support high-throughput screening campaigns, compound collections have to be in suitable formats, which requires a process known as compound reformatting. Here we report our approach to reformat the newly-establi...

This paper evaluates the ability of a variety of commercial and non-commercial software products to detect serial run-time errors in C and C++ programs, to issue meaningful messages, and to give the line in the source code where the error occurred. The commercial products, Insure++ and Purify, evaluated did the best of all the software products we evaluated. Error messages were usually better a...

In this paper we demonstrate how genetic programming can be used to interpret time dependent facial expressions in terms of emotional stimuli of different types and intensities. In our analysis we have used video records of facial expressions made during the Mars-500 experiment in which six participants have been isolated for 520 days to simulate flight to Mars. The FaceReader, commercial softw...

Several processes have been advanced in the literature for reverse engineering of relational databases. The inputs to these processes are relational tables and available contextual information. The output is a model of the underlying logical intent, apart from the implementation artifacts. Most of the existing processes for database reverse engineering are inadequate; they assume too high a qua...

A network of polymers can imbibe a large quantity of a solvent and swell, resulting in a gel. The swelling process can be markedly influenced by a mechanical load and geometric constraint. When the network, solvent, and mechanical load equilibrate, the gel usually swells by a field of inhomogeneous and anisotropic deformation. We show that this field in the swollen gel is equivalent to that in ...

BACKGROUND Parents' knowledge influences decisions regarding medical care for their children. METHODS Parents of pediatric primary care patients aged 9-14 years, irrespective of height, participated in open focus groups (OFGs). Moderators asked the question, 'How do people find out about growth hormone (GH)?' Because many parents cited the Internet, the top 10 results from the Google searches...

Airborne light detection and ranging (lidar) has become a powerful support for acquiring geospatial data in numerous geospatial applications and analyses. However, the process of extracting ground points accurately and effectively from raw point clouds remains a big challenge. This study presents an improved top-hat filter with a sloped brim to enhance the robustness of ground point extraction ...
