1. Overview In this brief position statement I will describe my own orientation towards the themes of this working group, and a project recently begun at GMD which I feel is relevant to these themes. As a system developer, the notion of a ‘common information space’ has certain connotations, and I will therefore elaborate on my own perspective of a CIS in the following section. Much of the activ...

In its most common linguistic use speci city refers to a kind of de niteness This is expressed by the grammatical marking on an NP showing that the speaker knows the identity of the referent Thus a police chief has presum ably a particular Colombian in mind when he utters My agents cannot wait to interrogate the Colombian While the above explanation seems straightforward speci city has come to ...

Abstract A widely held rights-based view asserts that individuals should be permitted to self-designate characteristics such as race and gender. But some argue there are opinions oppose the use only of self-designation, these not ignored. Kasher Rubinstein (Logique Anal 160:385–395, 1997) demonstrated latter is equivalent accepting one or more five conditions must violated. This paper extends t...

In this article I deal with time as a notion of epistemological content associated though with the notion of a subjective consciousness co-constitutive of physical reality. In this phenomenologically grounded approach I attempt to establish a ‘metaphysical’ aspect of time, within a strictly epistemological context, in the sense of an underlying absolute subjectivity which is non-objectifiable w...

Reinhold Kröger studierte Informatik an der Universität Bonn, wo er auch mit einer Arbeit über verteilte Betriebssysteme promovierte. Anschließend war er ca. 10 Jahre in der GMD als Wiss. Mitarbeiter und Projektleiter tätig. Seit 1993 ist er Professor für Betriebssysteme und Verteilte Systeme an der Fachhochschule Wiesbaden – University of Applied Sciences. Dort leitet er das Labor für Verteilt...

The nearby, 30 to 40 Myr old, starburst region of the Gould Belt has formed numerous massive stars. Within its ∼300 pc radius, it produces core-collapse supernovae at an enhanced rate which is shown to be 75 to 95 Myr kpc, i.e. 3 to 5 times higher than the local Galactic rate, over the past and future few million years. A population of persistent, but unidentified, γ-ray sources has been recent...

In this paper, we propose a new minimum total communication distance (TCD) algorithm and an optimal TCD algorithm for broadcast in a 2-dimension mesh. The former generates a minimum TCD from a given source node, and the latter guarantees a minimum TCD among all the possible source nodes. These algorithms can be generalized to a d-dimensional mesh or torus. TCD can potentially be used as a measu...
