The article deals with stabilisation and regeneration of CeO2 and CeO2/ZrO2 based Pt water gas shift catalysts, subject to high initial deactivation. The reaction gas species effect on the catalyst deactivation was investigated by H2-TPR. Activity measurements enabled the effect of different promoters, some added to the CeO2 based catalysts and some to the CeO2/ZrO2 based Pt catalysts, to be inves

In this paper we study an optimization problem relevant for wireless networks. In such networks links are subject to capacity disruptions caused by changing weather/channel condition that force to adapt the modulation and coding schemes to the observed condition. To cope with this issue in network optimization, we need to consider a so called link availability set A and a routing strategy that can

Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. The studies in this work invol

Verification and validation activities take a substantial share of project budgets and need improvements. This is an accepted truth, but the current practices are seldom assessed and analyzed. In this paper we present a qualitative survey of the verification and validation processes at 11 Swedish companies. The purpose was to exchange experience between the companies and to lay out a foundation fo

In recent years, the number of products that can be tailored to consumers' needs and desires has increased dramatically; there are many opportunities to individualize the colors, materials or options of products. However, current trends indicate that the future consumer will not be satisfied with mere material and color choices, but will desire control over form as well. While it is technically fe

I denna rapport sammanfattas aktuell medieforskning inom risk- och kriskommunikationsområdet. Författaren diskuterar även mediernas roll att informera, granska och förklara risker och kriser samt lokaliserar kunskapsluckor inom forksningen som i sin tur på sikt kan generera ny forksning.

Popular Abstract in Swedish Ärfltiga faktorer orsakar ledgångsreumatism Reumatoid artrit (RA) även kallat ledgångsreumatism är en ledsjukdom som drabbar 1% av befolkningen, framförallt kvinnor. Orsaken till sjukdommen är inte känd, men man tror att det finns en ärftlig faktor som avgör om en viss individ kan utveckla reumatoid artrit eller inte. Den genetiskassociationen man idag vet om är till mThe immune pathology and MHC association of chronic arthritis was studied in three rat models for reumatoid arthritis (RA). Susceptible rat strains develop a T cell dependent chronic disease after immunization with rat collagen type II (CII). The LEW rat does not develop arthritis after immunization with rat CII, but a heterologous immune response to pepsin can break the tolerance to CII and rende

In network design, the gap between theory and practice is woefully broad. This book narrows it, comprehensively and critically examining current network design models and methods. You will learn where mathematical modeling and algorithmic optimization have been under-utilized. At the opposite extreme, you will learn where they tend to fail to contribute to the twin goals of network efficiency and
