Die Zuse KG war zugleich eine Erfolgsund eine Misserfolgsgeschichte. Sie war ein Erfolg, weil es einem Außenseiter gelang, auf der Basis seiner Computererfindungen ein mittelständisches Unternehmen aufzubauen und zwischen 1949 und 1969 insgesamt mehr als 251 Rechenanlagen zu bauen. Sie wurde jedoch ein Mißerfolg, weil es Konrad Zuse nicht schaffte, den hohen Kapitalbedarf der Firma für den Umst...

In this study, two improved dental stones were used to fabricate master casts and dies. The tested fabrications were BegoStone (Bego Bremer, Goldschlägerei Wilh. Herbst GmbH and Co. Wilhelm HerbstStrabe 1 D 28359 Bremen Germany), Moldano (Heraeus Kulzer GmbH and Co. KG Gruner Weg 11 D-63450 Hanau Germany) and plaster of paris (BMT, PK 121 Sivas, Turkey). Together with the manufacturer’s values,...

Column and row operator spaces — which we denote by COL and ROW, respectively — over arbitrary Banach spaces were introduced by the first-named author; for Hilbert spaces, these definitions coincide with the usual ones. Given a locally compact group G and p, p ∈ (1,∞) with 1 p + 1 p = 1, we use the operator space structure on CB(COL(L ′ (G))) to equip the Figà-Talamanca–Herz algebra Ap(G) with ...

Stefan Paulsen absolvierte ein Informatik-Studium an der Fachhochschule in Flensburg und schloss dieses 2007 als DiplomInformatiker ab. Schon während des Studiums war er bei der Firma ITD Informationstechnologie GmbH&Co. KG als Entwickler von IP-Messsystemen tätig. Zwischen 2007–2009 arbeitete er als Programmierer bei der Bodo Peters GmbH, die ihn mit der Neuentwicklung eines Asset Management S...

For a prime p let G be a finite p-group and K a field of characteristic p. The Modular Isomorphism Problem (MIP) asks whether the modular group algebra KG determines the isomorphism type of G. We briefly survey the history of this problem and report on our computer-aided verification of the Modular Isomorphism Problem for the groups of order 512 and the field K with 2 elements.

As discussed in Section 3 of the main paper, the KG policy posseses several optimality and convergence properties. First, it is optimal by construction when N = 1 (Remark 1). Second, the suboptimality gap between the values of the KG and the optimal policies narrows to 0 as N →∞ (Theorem 4). This is a convergence result, since it shows that when sampling under the KG policy we are guaranteed to...

In the modern era, abundant information is easily accessible from various sources, however only a few of these sources are reliable as they mostly contain unverified contents. We develop a system to validate the truthfulness of a given statement together with underlying evidence. The proposed system provides supporting evidence when the statement is tagged as false. Our work relies on an infere...

We derive a one-period look-ahead policy for finiteand infinite-horizon online optimal learning problems with Gaussian rewards. The resulting decision rule easily extends to a variety of settings, including the case where our prior beliefs about the rewards are correlated. Experiments show that the KG policy performs competitively against other learning policies in diverse situations. In the ca...
