We consider thermal fluid structure interaction to model industrial gas quenching in steel forging, where hot steel Is cooled using cold high pressured gas. This allows to define properties of the finished steel part, as for example yield strength, locally at low cost and without environmental problems. For the numerical simulation, a partitioned approach via a Dirichlet-Neumann coupling and a fix
We use Cholesky decomposition of the density matrix in atomic orbital basis to define a new set of occupied molecular orbital coefficients. Analysis of the resulting orbitals ("Cholesky molecular orbitals") demonstrates their localized character inherited from the sparsity of the density matrix. Comparison with the results of traditional iterative localization schemes shows minor differences with
The parallel structure of dataflow programs and their support for processing streams of data make dataflow programming an interesting tool for doing stream processing on parallel processing architectures. The computational kernels, the actors, of a dataflow program communicate with other actors via FIFO channels. The actors in the dataflow model used in this paper may perform different actions dep
In this paper we present a novel 3D sensing approach for industrial bin-picking applications that is low-cost, fast and precise. The system uses a simple laser-line emitter. While a robot arm moves the object through the laser light, a synchronized camera captures the laser line image on the object. A full point cloud as well as an edge point cloud suitable for subsequent pose estimation is genera
The problem of reducing the number of multiplications in infinite response filtering is considered. We show how this operation may be decomposed on finite response filtrations and so-named halfconvolutions. Examples of the efficient procedures for filters of low order are presented.
Spontaneous activation of rhodopsin without light absorption occurs at a much lower rate in rod photoreceptors and insect rhabdoms than in cones. The difference lies in the pigment molecules themselves, and has implications for the design of visual photoreceptors.
We present new polynomial-time approximation schemes (PTAS) for several basic minimum-cost multi-connectivity problems in geometrical graphs. We focus on low connectivity requirements. Each of our schemes either signifi- cantly improves the previously known upper time-bound or is the first PTAS for the considered problem. We provide a randomized approximation scheme for finding a biconnected graph
We consider the capacity of multiple-input-multiple-output (MIMO) systems with reduced complexity. One link end uses all available antennas, while the other chooses the "best" L out of N antennas. The selection of the optimum antenna subset requires an exhaustive search of all possible combinations, involving (/sub L//sup N/) computations of determinants of size L /spl times/ L, which can become p
Sammanfattning Överlåtelser av företag är betydelsefulla affärshändelser med förhandlingar i flera omgångar. När inget annat är avtalat tillämpas köplagen som föreskriver en plikt för köparen att undersöka målbolaget, annars riskeras rätten att kunna åberopa fel gå förlorad. Felbedömningen tar utgångspunkt i köparens befogade förväntningar på målbolaget och som fel får inte åberopas vad som borde
The mission of the Centre for Engineering Education is to: - Facilitate educational development and training within the framework of Genombrottet. - Organize faculty-wide doctoral courses and training of PhD supervisors. - Organize Supplemental Instruction (SI) at the Faculty of Engineering and in collaboration with primary and secondary schools. - Deliver foundation education for access to engine
Effekter av inducerad hypotermi på hjärna och hjärta efter hjärtstillestånd Patienter i coma efter hjärtstillestånd vårdas på IVA och en majoritet behandlas med hypotermi i neuroprotektivt syfte. Hypotermins effekt på hjärtat är dåligt känd. I samarbete med sjukhusen i Malmö och Helsingborg samlar vi fortlöpande data från behandlade patienter och följer upp med återbesök hos neurolog efter 6 mån.Effects of actively induced hypothermia on the brain and the heart after cardiac arrest. Patients in coma after cardiac arrest will be treated by actively induced hypothermia in the intensive care ward with the aim of being neuroprotective. The effect of hypothermia on the heart is not known. In collaboration with the hospitals in Malmö and Helsingborg data from these patients are introduced in a
Ämnet Arkitektur, form och design fokuserar på själva skapandet av arkitektonisk form där arkitektur förstås som en rumslig materiell praktik vilken genererar sociala, kulturella och ideologiska betydelser. Ämnet ansvarar för en betydande del av undervisningen på Arkitektprogrammet men vi bedriver också forskning och konstnärligt undersökande projekt inom arkitektur och design. Den utåtriktade verThe subject of Architecture, Form and Design focuses on the actual creation of architectural form in which architecture is understood as a spatial material practice that generates social, cultural and ideological meanings. The subject forms a significant part of the instruction on the Architecture programme but we also conduct research and artistic exploratory projects within art and design. Our o
