This paper presents a two-phase heuristic methodology aimed at the reconfiguration of a radial distribution network with the objective of minimizing the computational time. In the preliminary phase of the operation, all network switches are in a closed state, and it is proposed that a subsequent switch opening methodology be employed to achieve a configuration that approximates optimal radial char

In this paper we will prove the uniqueness of a solution to Helmholtz' equation for two halfspaces of different media in $n$ dimensions. The theorem allows a finite number of bounded inhomogeneities in each half space. The surface separating the half spaces is assumed to be a cone of arbitrary cross section far away from the origin and is furthermore assumed to be smooth. We assume all space to be

Extraordinary transmission through subwavelength apertures is usually observed in a narrow bandwidth range, and the transmission outside this range is low, in agreement with classical results. The analysis presented here is based on the Babinet's principle and hence scattering by the complementary structure, where the apertures are replaced by finite scatterers. It is shown that the transmission c

Pseudogenes, nonfunctional copies of genes, evolve fast due the lack of evolutionary pressures and thus appear in several different forms. PseudoGeneQuest is an online tool to search the human genome for a given query sequence and to identify different types of pseudogenes as well as novel genes and gene fragments.

The Functional Mockup Interface (FMI) is a tool independent standard for the exchange of dynamic models and for co simulation. The first version, FMI 1.0, was published in 2010. Already more than 30 tools support FMI 1.0. In this paper an overview about the recently published version 2.0 of FMI is given that combines the formerly separated interfaces for Model Exchange and Co-Simulation in one sta

Recent observations by the Goddard High-Resolution Spectrograph on the Rubble Space Telescope have dramatically improved our knowledge of the abundance of the heaviest elements in Mercury-Manganese (HgMn) stars (c.f. Leckrone et al. 1992 and Wahlgren et al. 1995). Explaining the observed abundance and isotope anomalies requires improved calculations of radiatively driven diffusion. We briefly revi

Nature provides us with a vast source of inspiration. However, given industrial designers' open-mindedness and inquisitiveness, a surprisingly limited set of nature-derived symbols continues to be popular in this creative discipline. Rather than designing products mimicking nature, it is probably more rewarding designing them based on the natural principles leading to its growth and form. However,

The paper addresses the challenges of supply chain management in the electronics sector influenced by the trends of globalisation, production outsourcing and emerging product-related environmental policies. The trends have forced the original equipment manufacturers (OEMs) to take eco-design and supply chain management (SCM) initiatives, which pose challenging demands on the suppliers in developin

Popular Abstract in Swedish Avhandlingen är en granskning av ett antal psykologiska metoder i syfte att förbättra bedömning/diagnostik av två olika tillstånd förknippade med kontakt med kemikalier: (1) kronisk nedsättning av hjärnfunktion till följd av långvarig kontakt med lösningsmedel i yrket (toxisk encefalopati, förkortat TE), och (2) överkänslighet för kemikalielukter av okända orsaker (eng.The dissertation deals with psychological methods aimed at improving the understanding and assessment of two disorders related to contact with chemicals: solvent-induced chronic toxic encephalopathy (TE) and multiple chemical sensitivity (MCS). The main aim of Paper I was to study whether the addition of some newer psychological tests of complex attention and executive functions to a traditional

Popular Abstract in Swedish Sedan kartläggningen av det mänskliga genomet, har mer fokus lagts på dess produkt, proteomet, som definieras som de proteiner som uttrycks i en cell vid en viss tidpunkt. Proteomets dynamiska egenskaper gör det till en fantastisk källa för så kallade biomarkörer, det vill säga molekyler som genom deras koncentrationsmönster kan användas för att särskilja sjuka och frisMultiplex protein quantification, proteomics, is essential for uncovering new biomarkers and understanding biology. Liquid chromatography coupled to mass spectrometry (LC-MS) is the predominant technique for these measurements. In this thesis, optimization and quality control strategies for different phases of the LC-MS pipeline have been developed. Due to the inherent complexity and dynamic rang

A simple analytical model for the link loss between two very low profile wireless body area network transceivers located at the same level on the human torso is presented. The model is based on the attenuation of the creeping waves on an elliptical approximation of the human torso. A good agreement between the model and the FDTD simulations on realistic heterogeneous phantoms of different age and

Popular Abstract in Swedish Partikelfysiken är studien av naturens minsta beståndsdelar --- De så kallade \emph{elementarpartiklarna}. All materia i universum består av elementarpartiklar. Den teori som beskriver vilka partiklar som finns och hur de uppför sig heter \emph{Standardmodellen}. Teorin har historiskt sett varit mycket framgångsrik. Den har gång på gång förutspått existensen av nya partThis thesis documents my work in the luminosity and supersymmetry groups of the ATLAS experiment at the Large Hadron Collider. The theory of supersymmetry and the concept of luminosity are introduced. The ATLAS experiment is described with special focus on a luminosity monitor called LUCID. A data-driven luminosity calibration method is presented and evaluated using the LUCID detector. This method
