Das E-Assessment-System JACK der Universität Duisburg-Essen bietet eine server-basierte, interaktive Übungsund Prüfungsplattform zur Unterstützung von ProgrammierLehrveranstaltungen an. Mittels modularer sprachspezifischer Prüfkomponenten (Checker) können automatisiert Quellcodedateien korrespondierender Programmiersprachen auf ihr Laufzeitverhalten und ihre interne Struktur untersucht werden. ...

We study the averages of ratios of characteristic polynomials over circular β-ensembles, where β is a positive real number. Using Jack polynomial theory, we obtain three expressions for ratio averages. Two of them are given as sums of super-Jack polynomials and another one is given by a hyperdeterminant. As applications, we give dualities for ratio averages between β and 4/β. MSC-class: primary...

A few months after Jack Schwartz’s death on March 2, 2009, a memorial gathering was held for him at the Courant Institute of New York University, his home base for almost fifty years. The well-planned program included a few piano pieces and almost a dozen speakers, each of whom had collaborated with Jack in one or more of his many activities. Those present would have heard the speakers talk about:

Virtual prototyping emerges as a new technology to replace existing physical prototypes for product evaluation, which are costly and time consuming to manufacture. Virtualization technology allows engineers and ergonomists to perform virtual builds and different ergonomic analyses on a product. Digital Human Modelling (DHM) software packages such as Siemens Jack, often integrate with CAD system...

The Health and Safety Executive have commissioned KW Ltd to carry out a fundamental assessment of the dynamic characteristics of jack-up structures. The overall objective of the study is to develop an understanding of the possible failure modes of such structures and to prepare a basis for the fundamental modelling of the dynamic interaction of the structure, loading and foundations of jack-up ...

Applying Baxter’s method of the Q-operator to the set of Sekiguchi’s commuting partial differential operators we show that Jack’s symmetric polynomials P (1/g) λ (x1, . . . , xn) are eigenfunctions of a one-parameter family of integral operators Qz . The operators Qz are expressed in terms of the Dirichlet-Liouville n-dimensional beta integral. From a composition of n operators Qzk we construct...

It is a challenge to find point wise (including inter-element boundary) divergence-free finite element bases. By identifying functions in the kernel of the divergence operator, we discover a local basis for the full divergence-free space of the C0-P1 finite element, on the union jack grid. The optimal order of approximation is shown for the P1 divergence-free finite elements on union jack grids...

Jack polynomials in superspace, orthogonal with respect to a “combinatorial” scalar product, are constructed. They are shown to coincide with the Jack polynomials in superspace, orthogonal with respect to an “analytical” scalar product, introduced in [5] as eigenfunctions of a supersymmetric quantum mechanical many-body problem. The results of this article rely on generalizing (to include an ex...
