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

Inom sociala rörelser har emellanåt närts tanken på att ett nytt samhälle kommer att befolkas av en ny sorts människa. Brottet med det förflutna, befläckat av förtryck och förnedring, skulle alltså innebära ett så radikalt omstöpande av de sociala relationerna att människans förhållningssätt och egenskaper i grunden skulle förändras. Under moderniteten löper ett mäktigt band av utopiska föreställn

This data set contains the data from the Ulysses dust detector system (UDDS) from start of mission through the end of mission, 1990-2007. (As the dust detector was turned off after Nov. 30, 2007, this is the last date for which UDDS data is recorded.) Included are the dust impact data, noise data, laboratory calibration data, and location and orientation of the spacecraft and instrument.
