The INFORMS Case Competition and the Case for Cases KU Leuven
For more than 20 years, the INFORMS Case Competition has promoted the development and teaching of a diverse collection of cases by INFORMS members across the globe. Through this competition, INFORMS showcases effective original cases, builds a repository of cases and associated teaching notes, expands the library of cases that are freely available to faculty and students (particularly important for our colleagues in developing nations who wish ...
Integrating Type Theory and Distributional Semantics: A Case Study on Adjective-Noun Compositions KU Leuven
Case Studies in Competition Policy Research: A Systematic Literature Review Vrije Universiteit Brussel
The case study constitutes an important methodology in academic research, also in the field of competition policy. However, to the best of our knowledge, an elaborate review on how the case study method is applied in competition policy research is still missing. In response, this article presents a systematic literature review that comprehensively explores this topic through seven sub-questions: in which policy areas are case studies ...
A study on prospective associations between adiposity and 7-year changes in movement behaviors among older women based on compositional data analysis Universiteit Gent
Novel metamodel-based optimization approach for game theoretical analyses in mobility ecosystems and its demonstration via a case study about toll competition KU Leuven
First, a concept of novel metamodel-based optimization, in which a transport economics inspired model acts as a metamodel over an underlying set-up of directly interfaced transport models, is discussed. It is hypothesized that this approach allows to solve transportation problems, at a fea sible computational cost, with due consideration to relevant interactions between different stake holders/(sub)systems. Then, a case study concerning toll ...
Region competition based active contour for medical object extraction Vrije Universiteit Brussel
In this paper, a probabilistic and level set model for three-dimensional medical object extraction is proposed, which is called region competition based active contour. The algorithms are derived by minimizing a region based probabilistic energy function and implemented in a level set framework. An additional speed-controlling term makes the active contour quickly convergent to the actual contour on strong edges, whereas a probabilistic model ...
Reduced-rank approximations to spectroscopic and compositional data: a universal framework based on log-ratios and counting statistics KU Leuven
© 2015 Elsevier B.V. Although not immediately apparent, acquisition of all spectroscopic and all compositional data involves counting or a similar process. Therefore, these data are subject to counting errors. In this contribution, the performance of Reduced Rank Approximation (RRA) methods was investigated which accommodate for counting errors to a different extent. Our premise is that count data can be treated as compositional quantities and ...
