A fundamental building block of any Grid infrastructures is the Grid information service and the information model. The information model describes the entities and relationships between entities within the infrastructure along with their semantics. The realization into a concrete data model defines the syntax by which these concepts can be exchanged. This data model enables consumers of informati
Given an input consisting of an n-vertex convex polygon with k hole vertices or an n-vertex planar straight line graph (PSLG) with k holes and/or reflex vertices inside the convex hull, the parameterized minimum number convex partition (MNCP) problem asks for a partition into a minimum number of convex pieces. We give a fixed-parameter tractable algorithm for this problem that runs in the followin
A critical assessment of a widely applied approach for the prediction of temperature-insensitive absorption lines is presented. This approach was found to suffer from significant shortcomings.
The major challenge in the development of new polymer membranes for fuel cells lies currently in the demand for durable membranes that allows fuel cell operation at high temperatures without extensive humidification requirements. Access to these membranes promises important benefits concerning the complexity, cost and performance of the fuel cell system. In this context, membranes functionalized w
Injection into the MAX IV Storage Rings will not make use of a conventional local injection bump with dipole kickers. Instead, pulsed multipole injection will be applied. Previously, it was foreseen to use a pulsed sextupole magnet similar to what KEK had originally designed for the PF ring. But after seeing encouraging results with a prototype nonlinear kicker magnet developed for BESSY-II, pulse
The performance of a turbo code is dependent on two properties of the code: its distance spectrum and its suitability to be iteratively decoded. Both these properties are dependent on the specific interleaver used in the turbo-coding scheme. This paper describes a strategy for interleaver design that includes a criterion for the performance of iterative decoding. This criterion is based upon corre
Abstract Recent years have seen a number of competing theories of concepts within philosophy of mind, supplanting the classical definitionist and imagist accounts: among them, Jerry Fodor's informational atomism, Jesse Prinz's proxytypes theory, and -- of course -- Peter Gärdenfors' (2004) conceptual spaces theory (CST). On the whole there has been little empirical investigation into the competing
A novel method for the synthesis of spherical molecularly imprinted polymer (MIP) beads by suspension polymerization in mineral oil is described. The usefulness of the method was demonstrated by the synthesis of a propranolol imprinted MIP library. The composition of the library was generated by statistical experimental design. Multivariate data analysis correlated the screening data, obtained by
In this study the elasto-plastic constitutive equations are reformulated using the assumption of constant strain rate direction within a load increment. This assumption allows the constitutive evolution laws to be rewritten as ordinary differential equations (ODEs). The set of ODEs is reduced using the Krieg and Krieg description of the deviatoric stress space. Although this approach does generall
Living with dementia means struggling to preserve a sense of self, to retain (and reevaluate) one's values in a new situation, and to search for a new way of life. This study explored the meaning of everyday life as expressed by 11 people suffering from dementia. Data were collected through interviews with people in the early stage of a diagnosed dementia disease. The findings indicate that many p
Two different self-adjoint Pauli extensions describing a spin-1/2 two-dimensional quantum system with singular magnetic field are studied. An Aharonov-Casher type formula is proved for the maximal Pauli extension and the possibility of approximation of the two different self-adjoint extensions by operators with regular magnetic fields is investigated.
The aim of this study was to investigate the specificity of the H-3-triolein assay and to investigate the recovery of highly purified pancreatic lipase and pancreatic lipase in the form of pure non-activated pig pancreatic juice. Blood plasma from pigs was analysed for pancreatic lipase activity using the H-3-triolein substrate assay, with a method specific for lipoprotein lipase and with a method
Wireless Personal Area Networks (WPAN) has gained interest in the last few years and several air interfaces have been proposed to cover WPAN applications. A Multi-Carrier Spread Spectrum (MC-SS) air interface specified to achieve 130 Mbps in typical WPAN channels, is presented in this paper. It operates in the 5.2 GHz ISM band and achieves a spectral efficiency of 3.25 b.s-1.Hz-1. Besides the robu
We report on a large scale calculation concerning the 5s(2) S-1 and 5s5p P-1,P-3 levels in Sr-88 I, using multiconfiguration Dirac-Fock methods. Our focus is on the P-3(2) meta-stable level, which has been shown to be extremely useful in atom cooling and trapping experiments. The lifetime for this level from our work (1071 s) agrees very well with a previous theoretical value, but not with the ava
