Chapter XIX Object - Relational Modeling Jaroslav

IntroductIon Modeling techniques play an important role in the development of database applications. Well-known entity-relationship modeling and its extensions have become a widely-accepted approach for relational database conceptual design. An object-oriented approach has brought a new view of conceptual modeling. A class as a fundamental concept of the object-oriented approach encapsulates bo...

Jaroslav Hájek and asymptotic theory of rank tests

In the series of papers [1-3,5,6,8,9,11,12] (papers [11] and [12] were written joint­ ly with V. Dupac), Hajek systematically investigated the asymptotic properties of linear rank statistics under null hypotheses, under local (contiguous) and some non­ local alternatives. Besides that , in [4] he derived the rank test of independence in a bivariate distribution, locally most powerful against sp...

Jaroslav Peregrin What is the Logic of Inference ?

The topic of this paper is the question whether there is a logic which could be justly called the logic of inference. It may seem that at least since Prawitz, Dummett and others demonstrated the proof-theoretical prominency of intuitionistic logic, the forthcoming answer is that it is this logic that is the obvious choice for the accolade. Though there is little doubt that this choice is correc...
