By a K3-surface with nine cusps I mean a surface with nine isolated double points A 2 , but otherwise smooth, such that its minimal desingularisation is a K3-surface. It is shown, that such a surfaceâ€¦ (More)

0 Introduction We consider algebraic surfaces Y âŠ‚ IP3(C). A cusp (=singularity A2) on Y is a singularity near which the surface is given in local (analytic) coordinates x, y and z, centered at theâ€¦ (More)

Up to now the maximal number of smooth conics, that can lie on a smooth quartic surface, seems not to be known. So our number 352 should be compared with 64, the maximal number of lines that can lieâ€¦ (More)

By a K3-surface with nine cusps I mean a compact complex surface with nine isolated double points A2, but otherwise smooth, such that its minimal desingularisation is a K3surface. In an earlier paperâ€¦ (More)

Performance Characteristics of Dual-Processor HPC Cluster Nodes Based on 64-bit Commodity Processors

Dual-processor nodes are the preferred building blocks in HPC clusters because of the greater performance-to-price ratio of such configurations relative to clusters comprising single-processor nodes.â€¦ (More)

U-beams from the MeVVa and the Penning ion source were used for machine investigations of the GSIUNILAC and synchrotron (SIS18). Carbon stripper foils (20, 40, 50 Î¼g/cm), temporarily replacing theâ€¦ (More)

In this paper we investigate when the generic member of a family of complex K3 surfaces admitting a nonâ€“symplectic automorphism of finite order admits also a symplectic automorphism of the sameâ€¦ (More)

We study a construction, which produces surfaces Y âŠ‚ IP3(C) with cusps. For example we obtain surfaces of degree six with 18, 24 or 27 three-divisible cusps. For sextic surfaces in a particularâ€¦ (More)

In this contribution, the concept of production of intense proton beams using molecular heavy ion beams from an ion source is described, as well as the indisputable advantages of this technique forâ€¦ (More)
