The Powers of the Union: Delegation in the EU

The Powers of the Union develops and exams a brand new idea of centralization and bureaucratization within the eu Union. utilizing unique information spanning 5 a long time and a multi-method technique, Franchino argues that almost all ecu legislation count widely on nationwide administrations for coverage implementation and supply for abundant nationwide discretionary authority, whereas restricting tightly the involvement of the eu fee.

Erfahrung — Bewegung — Strategie

Das 25jährige Jubiläum der ecu company university Schloß Reichartshausen (ebs) ist der Anlaß für diese Festschrift mit dem aus den Initialen der ebs abgeleiteten Titel: Erfahrung- Bewegung - Strategie. Jeder Hochschullehrer der ebs hat hierzu einen Beitrag aus seinem speziellen Forschungsgebiet verfaßt: In der Einführung wird die Entwicklung des Konzeptes der ebs wissenschaftlich analysiert, um daraus Perspektiven für die Zukunft abzuleiten.

Example text

However, even the compressed model sizes range from hundreds to tens of thousands of templates. Therefore, it is virtually impossible to anticipate (and manually craft) query patterns for a specific use case, especially if high recall levels are desired. Note that in contrast to whitelists, template model sizes do not necessarily grow with the increase in recall (despite spanning more queries). The reason is that as recall increases, more general templates (that often exhibit lower CTR) are included in the model, thereby causing more specific templates to become redundant.

Finally, we describe our implementation of a lightweight prototype TUC identification service that easily scales to support thousands of TUCs, and withstands high query loads with low latency. The rest of this paper is structured as follows. Section 2 surveys related work. Section 3 defines our metrics and optimization goals, whereas Section 4 describes the method for building the models. Section 5 presents the evaluation of our method across multiple transactional use cases. Section 6 overviews the TUC identification service, and Section 7 concludes the paper.
