Game Design As A Writing Course In The Liberal Arts., Amber Settle, Robin Burke, Lucia Dettori Dec 2006

Game Design As A Writing Course In The Liberal Arts., Amber Settle, Robin Burke, Lucia Dettori

Amber Settle

The School of Computer Science, Telecommunications, and Information Systems (CTI) is a technologically-focused college within DePaul University. While DePaul CTI has a large number of technical degree programs, DePaul University is a liberal arts institution and one that is increasingly focused on improving the writing skills of its students. It can be difficult to create courses that cover necessary technical material while requiring writing as a major part of the assessments. In this paper we discuss GAM 224: Introduction to Game Design, a required course in one of the specialized degree programs at DePaul CTI that involves writing in a …

Some Comparisons Among Quadratic, Spherical, And Logarithmic Scoring Rules, Eric Bickel Dec 2006

Some Comparisons Among Quadratic, Spherical, And Logarithmic Scoring Rules, Eric Bickel

Eric Bickel

Strictly proper scoring rules continue to play an important role in probability assessment. Although many such rules have been developed, relatively little guidance exists as to which rule is the most appropriate. In this paper, we discuss two important properties of quadratic, spherical, and logarithmic scoring rules. From an ex post perspective, we compare their rank order properties and conclude that both quadratic and spherical scoring perform poorly in this regard, relative to logarithmic. Second, from an ex ante perspective, we demonstrate that in many situations, logarithmic scoring is the method least affected by a nonlinear utility function. These results …

Gallium Update [In Hungarian], Fathi Habashi Dec 2006

Gallium Update [In Hungarian], Fathi Habashi

Fathi Habashi

Gallium is nearly 130 years old, first discovered in sphalerite in 1877 but now mainly recovered as a by-product of bauxite. Its compounds find a wide variety of applications in modern technology. A review of its discovery, methods of extraction, and its applications are given. Translated from 17th International Symposium of ICSOBA combined with Light Metals 2006 of the Metallurgical Society of CIM

Digital Elevation Accuracy And Grid Cell Size: Effects On Computed Topographic Attributes, Rob H. Erskine, Timothy R. Green Dec 2006

Digital Elevation Accuracy And Grid Cell Size: Effects On Computed Topographic Attributes, Rob H. Erskine, Timothy R. Green

Timothy R. Green

Terrain attributes are commonly used to explain the spatial variability of agronomic, pedologic, and hydrologic variables. The terrain attributes studied here (elevation, slope, aspect, and curvature) are estimated readily from digital elevation models (DEMs), but questions remain about how the accuracy and sample spacing of the elevation data affect the estimated attributes. The main objective of this study was to quantify differences in each terrain attribute due to factors affecting DEM accuracy and grid cell size. Three data sources were compared: (i) real-time kinematic global positioning system (RTKGPS); (ii) satellite-differentially corrected global positioning system (DGPS); and (iii) U.S. Geological Survey …
