Both numerical simulations and experimental measurements of small scale spontaneous ignition with different biomass fuels have been performed. In the experiments, temperature history was monitored at five different locations inside the fuel bed. The measured temperature history was used for validation of comprehensive threedimensional computer simulations which were carried out using a parallel fi

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,

In this paper. we present an analysis of different channel estimator structures that can be used and efficiently implemented with minor configuration changes of a common hardware for both LTE and DVB-H Such common estimator structures for LTE and DVB-H allow algorithm and hardware reuse when both standards are implemented on the same platform. In this approach, a core estimator will be utilized to

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

Fuel cells are electrochemical devices that convert chemical energy into electricity. Solid oxide fuel cells (SOFCs) are a particularly interesting type because they can reform hydrocarbon fuels directly within the cell, which are possible thanks to their high operating temperature. The purpose of this study is to develop an anode-supported SOFC theoretical model, to enhance the understanding of t

Popular Abstract in Swedish Strålbehandling av cancerpatienter sker idag med avancerad teknik och utrustning. Förberedelserna inför behandlingen är omfattande och kräver medverkan av flera olika personalkategorier och övervakning via datoriserade verifikationssystem. I varje led i förberedelsekedjan finns en potentiell risk för avvikelser, vilka kan vara både systematiska eller tillfälliga i sin nThe aim of this work was to develop, implement and evaluate an independent system with which to calculate the absorbed dose, delivered by high-energy X-ray beams, to the prescription point and the depth of dose maximum. The introduction of such a system in the clinical routine may help ensure high-quality treatment and avoidance of errors which may jeopardise the clinical outcome of the treatment

The objective of this paper is to describe the evaluation and effects of a major reconstruction of an arterial street in Eskilstuna, a medium sized Swedish town. The aim of the reconstruction was to minimize the barrier effects of the arterial street and by that create a stronger connection between the town center, on one side of the street, and the town-river, on the other; but also to create gen

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

Packaging and the role it plays in supply chain efficiency is overlooked in most design and development research. An opportunity exists to meet the needs of supply chains to increase efficiency. This research presents three propositions on how to reduce the gap between supply chain needs and satisfaction in interaction with the product and packaging system. It also proposes a supply chain focused

Syftet med denna studie är att undersöka hur avsättningen av biomassa kan öka inom de närmaste 10-20 åren för produktion av värme, el och drivmedel i Sverige. I dessa analyser förutsätts biomassan användas på ett resurs- och kostnadseffektivt sätt, vilket exempelvis innebär att värmeunderlagen är styrande för den potentiella avsättningen av biomassa i kraftvärmebaserad elproduktion och framtida dr
