In this work, we examine how to reliably exploit baseline diversity of a multichannel interferometric SAR system to overcome the layover problem. The problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or discontinuities in the sensed scene. Several multilook approaches have recently been suggested to c
The chapter introduces the overriding question of the volume—whether poor countries can catch up—by providing an overview of theories and approaches that have contributed to this discussion. It argues for the importance of introducing to the analysis the role of structural transformation and to acknowledge that the conditions for economic development vary from case to case. Instead of clinging on
Popular Abstract in Swedish Immunsystemet är vårt skydd mot främmande organismer såsom bakterier och virus. När vi får en förkylning, eller en infektion, tar immunsystemets celler hand om och dödar de invaderade mikroorganismerna. I normala fall märker vi endast av detta i form av att vi känner oss sjuka med eventuell feber som följd. Det ställs stora krav på immunsystemet. Det ska inte bara kunnaCollagen-induced arthritis (CIA) and pristane-induced arthritis (PIA) are animal models for human rheumatoid arthritis (RA), and can be induced in susceptible mouse and rat strains. CIA is induced by immunization of type II collagen (CII), a cartilage specific protein together with Freund’s adjuvant. PIA is induced by intradermal injection of pristane (2,6,10,14-tetrametylpentadecane). In rats, in
I will start out with an overview of common assumptions on the impact of free trade on the environment – assumptions which, very much like the first part of Lamy’s statement, are all-encompassing and deterministic. From there, I will narrow down the scope of examination to specific and immediate hardware-to-hardware impacts: akin to the second part of the above statement, the emphasis shall be put
The composition of the labour force is an important economic factor for a country. Often the changes in proportions of different groups are of interest. In this paper we study a monthly compositional time series from the Swedish Labour Force Survey from 1994 to 2005. Three models are studied: the ILR-transformed series, the ILR-transformation of the compositional differenced series of order 1, and
RFID technology can improve inventory and pipeline visibility. However, there is scarce research on how to tactically and operationally make use of RFID-captured data. The purpose of this paper is thus to explore the advantages and characteristics, from a material control perspective, of keeping track of goods in real time in a supply chain. A framework regarding the potential gains of tracking u
Proton scattering has been applied to the problem of elemental quantitative analysis of air particulate matter. Elements up through chlorine may be resolved using 16 MeV protons incident upon targets up to about 1 mg/cm2 in thickness. Using the FSU Super FM Tandem Accelerator and a large area solid state proton detector, an analysis can be performed in several minutes. Combination of this techniqu
SOFC systems, working at high temperatures of about 800°C, have recently attracted significant interests for application as automotive and stationary power supply systems. This paper explores the possibilities and limitations for achievement of solid oxide fuel cells (SOFCs) as 7 kW auxiliary power units on luxury passenger vehicles operating on diesel fuel. Various issues are discussed, e.g., the
Today’s multimedia systems use different types of media with different play-out devices. Currently we are heading towards a situation where for example cellular content providers, the home entertainment industry and networked multimedia over the Internet provide different content and dirferent formats that are incompatible with devices from the other systems. This is in stark contrast with the cur
Popular Abstract in Swedish I denna avhandling har jag fördjupat mig i de ekologiska sambanden mellan några av de mest påtagliga och kända organismerna i sjöar och dammar, nämligen sjöfåglar, undervattensväxter, smådjur (från och med nu kallade evertebrater, vilket betyder ryggradslösa djur), och i viss grad fisk. Bland sjöfåglarna (här avses främst änder, gäss, svanar och sothöns) finns det både The aim of this thesis was to explore some of the important links between waterfowl and the biota in shallow eutrophic lakes in temperate areas. Waterfowl depend on macroinvertebrates as sources of protein and calcium, which are essential for egg production and growth. Macroinvertebrates in turn depend on submerged vegetation for food and shelter. Increased density of vegetation thus leads to incr
Over the last ten years, there has been a great deal of research and development in Sweden in the field of rehabilitation robotics. The research effort has often focused on workplace adaptations. This paper deals with four robotic adaptations, all of whic
This paper presents a study wherein computer supported visualization is used to design and enhance understanding of quality systems. The study attempts to discover if a quality system such as ISO 9000 can be visualized, and how the visualization should be designed in order to support continuous improvement. Three companies in southern Sweden have set up special groups (here called design groups) w
De moderna kvinnorna med korta kjolar och ännu kortare hår som jazzade sig igenom 1920-talets nöjesliv är en bild som reproduceras i populärkulturen än idag. Men de moderna kvinnorna sågs i sin samtid inte endast som nöjeslystna kommersiella produkter, utan användes som en arena för att diskutera frågor om nationalitet, rasbiologi, genus, kropp och det moderna samhällets utmaningar. De moderna kvi
