Popular Abstract in Swedish Utveckling av nya industriella produkter sker allt oftare med hjälp av datormodeller. Dessa modeller beskriver fysiken för respektive produkt, vilket exempelvis kan vara en bil eller ett kraftverk. Med hjälp av modellerna kan en stor del av analyserna på de framtida produkterna ske med hjälp av datorer, varför färre prototyper behöver konstrueras, vilket medför kortare Simulation of coupled dynamical systems, where the subsystems are bundled with their own internal solver, is important in industry. This is due to that in many cases, with complex systems, this is the only viable option. In this setting, the dynamics of each system is hidden and information between subsystems is exchanged through sampled inputs and outputs, a weakly coupled system. While a new ind

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

Water and salt mass balances for the Dead Sea were modeled to consider different possible methods for maintaining its water level and water volume. In the models, precipitation, evaporation, rivers, ground water, input/output from potash companies and salt production, and brine discharge were included. The mixing time in the Dead Sea was modeled by a 1) single-layer (well-mixed) system, and a 2) t

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 Denna avhandling riktar fokus mot en paradox: statsmaktens kontroll och social frihet över Internet ökar parallellt i Kina. Studien, som baseras på fältarbete utfört mellan 2002 och 2006 och 48 intervjuer, söker finna svaren på två frågor: 1. Hur kan internetanvändningen bidra till ett öppnande av den publika sfären, på ett sätt som gör den mer oberoende av enpartistateThe aim of this dissertation is to address a paradox: government control and social freedom on China's Internet are growing simultaneously. The study, which is based on fieldwork conducted between 2002 and 2006, and 48 interviews, seeks answers to the following two questions: 1. How can Internet use contribute to an unlocking of the public sphere, making it more independent from party-state contro

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

Under de senaste åren har stora resurser lagts på forskning kring utvecklingen av biomaterial för ersättning av fossil-baserade material. Förpackningsindustrin i synnerhet är en sektor känd för att generera enorma mängder fast avfall, med produkter som inte sällan har betydligt kortare livslängd än sina materialkomponenter. Polylaktid (PLA) är en mångsidig biopolymer som används kommersiellt föIn recent years, large efforts have been put into the research of biomaterial synthesis for the replacement of fossil-based materials. Particularly in the packaging industry, a sector responsible for generating enormous amount of solid waste in which products have a considerably shorter life span than their material components. Polylactic acid (PLA) is a versatile, commercial biopolymer used fo

Since the establishment of an Islamic regime in Iran 1979, the poverty in the country has grown, especially among the middle class. This has occurred despite growing national prosperity, a solider government budget and decades of management experience. To understand this paradox, there is a need for research focusing on the connection between poverty and regime security. By using Critical Discours

The aggregation of proteins into amyloid fibrils via erroneous folding, also known as misfolding, occurs in several diseases. As a consequence, the study of the kinetics and thermodynamics of this process is currently intensely pursued. Here, we study a minimalistic lattice-based model for amyloid formation using Monte Carlo techniques to sample the grand canonical ensemble, where the chemical pot

The relationship between business cycles and mortality has been a highly debated subject in the field of economics. The majority of previous studies, using the unemployment rate as the main proxy for macroeconomic conditions, have found ambiguous effects largely depending on how the effect is estimated. This thesis follows the methodology used by Ruhm (2000), but instead applies aggregate data for

Syftet med studien är att undersöka kundlojalitet på lågengagemangsmarknader och därigenom förstå och redogöra för om företag som erbjuder lågengagemangsprodukter kan uppnå sann kundlojalitet utifrån sitt produkt- och serviceerbjudande och i så fall hur de detta kan göras. Denna abduktiva studie är utformad utifrån en kvalitativ ansats med inslag av kvantitativ metod i form av fokusgrupper, observThe purpose of this study is to analyze the customer loyalty that exists in a low-involvement market. The study will enable an understanding for if companies selling low-involvement products can attain true customer loyalty through the product and service offered, and if so, how this can be accomplished. This abductive study is using a qualitative framework with elements of a quantitative method b

The DARPA Grand Challenge (DGC) 2005 was a competition, in form of a desert race for autonomous ground vehicles, arranged by the U.S. Defense Advanced Research Project Agency (DARPA). The purpose was to encourage research and development of related technology. The objective of the race was to track a distance of 131.6 miles in less than 10 hours without any human interaction.
