The first essay empirically examines the effect of vertical integration on downstream market outcomes. Theory shows that vertical integration can promote efficient trade by mitigating contractual problems between firms. It can also facilitate the strategic practice of market foreclosure, by which an integrated firm denies a rival access to downstream markets for the purpose of gaining market po...

This paper describes the UMCC-DLSI system in SemEval-2010 task number 17 (All-words Word Sense Disambiguation on Specific Domain). The main purpose of this work is to evaluate and compare our computational resource of WordNet’s mappings using 3 different methods: Relevant Semantic Tree, Relevant Semantic Tree 2 and an Adaptation of k-clique’s Technique. Our proposal is a non-supervised and know...

Besides basic models for longitudinal and lateral movement, a traffic simulation needs also models and algorithms for right-of-way rules. This publication describes how passing an intersection is modeled within SUMO, including a description of an earlier and the currently used model.

A linear pinch discharge above the Pease-Braginskii current and stabilized by axial shear flow can radiatively collapse to high densities. A thermonuclear detonation wave can then be launched from one end of the discharge channel by ignition with a powerful laser pulse. Axial shear flow stabilization may be realized by injecting a fast moving jet along the pinch discharge channel, possibly in c...

Merging of ontologies is a frequently addressed problem in the ontology literature. This paper argues that in general two even very similar ontologies cannot be merged. Further, where two ontologies can be merged their conceptualizations are special. They are systems of institutional facts which are interlocking. The argument is based on the literature of the federated database problem and on t...

Merged indexes are B-trees that contain multiple traditional indexes and interleave their records based on a common sort order. In relational databases, merged indexes implement “master-detail clustering” of related records, e.g., orders and order details. Thus, merged indexes shift de-normalization from the logical level of tables and rows to the physical level of indexes and records, which is...
