We present the Monte Carlo generator RacoonWW that computes cross sections to all processes e+e− → 4f and e+e− → 4fγ and calculates the complete O(α) electroweak radiative corrections to e+e− → WW → 4f in the electroweak Standard Model in double-pole approximation. The calculation of the tree-level processes e+e− → 4f and e+e− → 4fγ is based on the full matrix elements for massless (polarized) ...

Real-world networks exhibit significant community structure. Communities are sometimes explicitly known or defined (e.g., virtual groups that one joins in an online social network, departments in an organization), but are often determined using a community detection or a clustering algorithm. Given a weighted network, with edge weights denoting interaction strengths between vertices, and a mapp...

The paper presents a new stiffness modelling method for overconstrained parallel manipulators, which is applied to 3-d.o.f. translational mechanisms. It is based on a multidimensional lumped-parameter model that replaces the link flexibility by localized 6-d.o.f. virtual springs. In contrast to other works, the method includes a FEA-based link stiffness evaluation and employs a new solution str...

A brief review on virtual black holes is presented, with special emphasis on phe-nomenologically relevant issues like their influence on scattering or on the specific heat of (real) black holes. Regarding theoretical topics results important for (avoidance of) information loss are summarized.

This paper describes the application of an evolutionary algorithm, Restart Covariance Matrix Adaptation Evolution Strategy (RCMAES) to the Generation Expansion Planning (GEP) problem. RCMAES is a class of continuous Evolutionary Algorithm (EA) derived from the concept of self-adaptation in evolution strategies, which adapts the covariance matrix of a multivariate normal search distribution. The...

This paper addresses the problem of computing the fundamental matrix which describes a geometric relationship between a pair of stereo images : the epipolar geometry. In the uncalibrated case, epipolar geometry captures all the 3D information available from the scene. It is of a central importance for problems such as 3D reconstruction, self-calibration and feature tracking. Hence, the computat...
