Determination of the Accuracy of the Observations, by C. F. Gauss, Translation with preface

Bestimmung der Genauigkeit der Beobachtungen is the second of the threemajor pieces that Gauss wrote on statistical hypothesis generation. It continues the methodological tradition of eoria Motus, producing estimates by maximizing probability density, however absence of the change-ofvariables theorem causes technical di›culties that compromise its elegance. In eoria Combinationis, Gauss abandon...

We review links between three logic formalisms and three approaches to specifying operational semantics. In particular, we show that specifications written with (small-step and big-step) SOS, abstract machines, and multiset rewriting, are closely related to Horn clauses, binary clauses, and (a subset of) linear logic, respectively. We shall illustrate how binary clauses form a bridge between th...

The concept of model transformations is of increasing importance in different areas of Computer Science, but up to now, there is a lack of common understanding concerning the mathematical and practical point of view. In this paper, we discuss some of the different aspects. Especially interesting is the new proposal of the POPL’07 keynote speaker Don Batory claiming that model transformations sh...

In this paper we address the problem of autonomous navigation in very large unstructured environments. A new hybrid metric map (HYMM) structure is presented that combines feature maps with other metric representations in a consistent manner. The global feature map is partitioned into a set of connected local triangular regions (LTRs), which provide a reference for a detailed multidimensional de...
