Assessing the Performance of Sub-Millimetre Compact Object Detection Algorithms

Sub-millimetre astronomy is about to be transformed by the deployment of new detectors that can map larger images than previously possible. A particular issue in sub-millimetre astronomy is the automated detection of compact, irregular regions of emission known as clumps. There are numerous clump detection software packages freely available yet there is little consensus as to which is the most appropriate to use, as each package has its own systematic bias when performing clumpfinding. The purpose of this investigation was to investigate a number of these clumpfinding packages and determine where some of these biases may lie. The CUPID package is designed for the creation and detection of clumps within images. There are four algorithms for the detection of clumps; ClumpFind, FellWalker, GaussClumps, and Reinhold. Each algorithm was individually investigated using data from SCAMPS (the SCUBA Massive Precluster Survey), (Thompson et al., 2005) to determine the effect of changing their parameters; the algorithms were then compared against each other to examine how the results differed between them. Using Monte Carlo simulations, Gaussian artificial clumps (with known peak, size, location, and integrated flux) were inserted into an image and the algorithms were tested to determine which algorithm extracted the information with the greatest accuracy, and where the completeness limits lie with each algorithm. ClumpFind, FellWalker, and Reinhold detected a lower integrated flux level than was inserted; this effect was more evident in large, flat clumps. Due to the profile of the clump it was expected that GaussClumps would detect the integrated flux more correctly, as was the proven case

EVIDENCE - CONSTITUTIONAL LAW - USE OF STATUTORY PRESUMPTIONS IN CRIMINAL CASES

The recent efforts on the part of state legislatures to increase the effectiveness of their criminal codes has resulted in extending the use of the statutory presumption to new fields of criminal law. The reaction which necessarily follows such an innovation upon traditional practice has appeared in the form of renewed attacks upon the constitutionality of the device, accompanied by the usual expressions of alarm concerning the threat to liberty that lurks in the use of this mechanistic instrument of arbitrary oppression

Exploring Practical Potentials of Business Simulation Games

With the emergence of the digital generation, advances in technology, and the trend towards more experiential learning formats, business simulation games (BSGs) are increasingly used by educators today. Of interest in this paper is the extent to which serious game playing, for business and technology professionals, influences work behaviors in practice. This study explores the business professional’s sense-making process when consciously reasoning about how BSG learning influences business practice. We adapt Toulmin’s framework for deconstructing practical reasoning to capture, analyze, and elicit patterns within arguments made regarding the application of BSG learning to business practice. The findings contribute to theories related to BSGs, and thus would benefit those practitioners who use BSGs

Using ERP Systems in Education

Enterprise Resource Planning systems are the new solution to business systems. These systems provide comprehensive business functionality in an integrated fashion using a state-of-the-art IT architecture. This trend towards enterprise systems in large and mid-sized organizations has a significant impact on IS careers paths. Enterprise systems essentially change fundamental business work processes thus implying that the system that supports these processes, and the design and development of these systems, also changed. Yet, most IS curricula do not provide significant coverage of ERP concepts, nor do they graduate students who are knowledgeable about these systems and the impact that these systems have on industry. This paper identifies opportunities for incorporating the ERP body of knowledge into an IS program. The general spirit of the paper is that of experiential learning. That is, this paper focuses on curriculum that is enriched through the hands-on experience gained by students working on a real ERP system. The paper also discusses related topics such as costs and critical success factors
