We investigate the effects of fracture- and inclusion-induced seismic anisotropy in a carbonate reservoir rock and the resulting influence this anisotropy may have on surface seismic data. Whole-core velocity measurements made on a carbonate sample from the Gulf of Mexico show evidence of elastic anisotropy. Constraints on the style of this anisotropy are obtained from comparisons with effective m

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.

Popular Abstract in Swedish Tensider är amfifila molekyler, vilket innebär att de består av två delar. En av dessa är hydrofil (”vattenälskande”) och den andra är hydrofob (”vattenhatande”). Detta faktum ger tensider speciella egenskaper av vilken den viktigaste är att de självaggregerar i lösningsmedel (främst vatten), och bildar olika typer av aggregat, varav micellen är den mest kända. Dess spePhase diagrams of mixed alkylglucoside surfactants, n-nonyl-b-D-glucopyranoside and n-decyl-b-D-glucopyranoside (C9G1 and C10G1) have been examined for the purpose of determining the microstructure surrounding a closed-loop miscibiliyt gap. There are large deuterium isotope effects on the phase diagram. NMR-self diffusion, cryoTEM and TRFQ experiments show the presence of long interconnect network

Concerns have been raised about the marketization of science through the prevailing funding regime. However, the present article will discuss how it comes that the potentially marketable stem cell science is not more commercialized than what is currently the case. We approach this question by analysing discursive pluralism in defining the value of stem cells within a grant allocation process. More

The aim of this paper is to evaluate static and dynamic characteristics of a two-phase claw-pole motor. The static characteristics are calculated and measured respectively for a single phase-core assembled into the motor and for a complete motor. The dynamic characteristics of the motor are evaluated on the basis of non-linear static characteristics. Later, the control system that is designed in s

Underinvestment happens when an investor abstain from investing in an asset, even if the investment is beneficial for the customer, because it does not perceive a profitable return on the specific investment. The risk for underinvestment is high in projects which rely on high asset specificity and towards the end of contract lifespan. This paper builds upon a qualitative analysis of documentation

Popular Abstract in Swedish Denna avhandling behandlar komplexa optimerings problem med artificiella neuron nätverk (ANN) tekniker och diverse verktyg från den teoretiska fysiken. För många typer av komplexa optimerings problem kan den mänskliga hjärnan prestera ett snabbt och hyfsat bra svar. ANN bygger på en mycket rudimentär bild av hur det riktiga de riktiga neuronerna i hjärnan arbetar, syftPotts mean field artificial neural network techniques are developed and applied to airline crew scheduling problems and routing problems. A propagator formalism in terms of Potts neurons is developed to handle global topological issues. An integrated method for identifying and classifying ECG complexes is presented. Unsupervised self-organizing artificial neural networks are employed to cluster t

Denna rapport har kallats ”Man kan inte klara hur mycket som helst”, efter ett uttalande från en av de intervjuade cheferna. Studien ingår som ett led i KVAR-projektet vid Arbetslivsinstitutet Syd i Malmö. Vid intervjuerna framkom vissa faktorer i försäkringskassemedarbetarens arbetsmiljö som enligt chefernas beskrivning kan utgöra ett hot mot medarbetarnas hälsa och arbetstillfredsställelse. Ur c
