The development of public-domain software in the scientific community has stimulated a fast and free dissemination of ideas. Here we present latest contributions to public-domain radar interferometry software to create interferometric products and to analyze and visualize these products. We present the feasibility of the Doris radar interferometric software of Delft University of Technology to ...

This paper generalizes the methods developed in Shannon, Province and Rao (2001) to use recursive partitioning to identify subsets of the aggregate data within each of which simple linear regression models give better fit. This method is proposed as an alternative to multivariate regression modeling when the analyst is primarily concerned with the regression of an outcome onto a single predicto...

Software reliability is an important factor for evaluating software quality in the domain of safety-critical software. The neural network prediction method has been widely used in reliability prediction area. However, Data noise and other issues make this approach easy to falling into local optimum, and reduce the accuracy of the prediction, it also affect the applicability of the model. In thi...

Improvements in performance modeling and identification of computational regimes within software libraries is a critical first step in developing software libraries that are truly agile with respect to the application as well as to the hardware. It is shown here that Pareto ranking, a concept from multi-objective optimization, can be an effective tool for mining large performance datasets. The ...

Software systems evolve over time incrementally and sections of code are modified. But, how much does code really change? Lehman’s laws suggest that software must be continuously adapted to be useful. We have studied the evolution of several public domain object-oriented software systems and analyzed the rate as well as the amount of change that individual classes undergo as they evolve. Our ob...

BACKGROUND Although environmental characteristics as perceived by parents are known to be related to children's outdoor play behavior, less is known about the relation between independently measured neighborhood characteristics and outdoor play among children. The purpose of this study was to identify quantitative as well as qualitative neighborhood characteristics related to outdoor play by me...

SparQ is a toolbox for qualitative spatial reasoning. Interpreting reasoning in a broad sense, SparQ covers mapping information from quantitative to qualitative, applying constraint reasoning to qualitative information, reasoning about calculi, and mapping qualitative information back to the quantitative domain. The toolbox is designed for extensibility and released under the GNU GPL public lic...

The eeective analysis of three-dimensional biomedical images has application in a wide variety of medical applications , ranging from the analysis of unborn foetuses for heart defects to the facial reconstruction of murder victims. However, currently employed feedback techniques concerning analysis of three-dimensional image structures are themselves presented in the visual domain. This paper p...
