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
Problems related to content of fat, oil and grease (FOG) in wastewater is an increasing problem in Sweden. FOG can cause clogging in the sewage system and subsequent flooding and disturbance of processes in waste water treatment plants. The problem has previously been mostly been related to release of large quantities of FOG from restaurants and large scale industries which has caused problems in

Utvärderingar framställs som attraktiva och oundgängliga samtidigt som det förekommer begränsad kunskap om deras faktiska relevans och om utvärderares arbete. Utvärdering är numera såväl ett självständigt forskningsområde med en vetenskaplig och disciplinär utveckling som en praktik som bedrivs av forskare med vetenskapliga ambitioner, konsulter som arbetar på uppdrag och medarbetare inom organisa
Popular Abstract in Swedish I denna avhandling har olika analytiska provupparbetningsmetoder för bestämning av spårmetaller i komplexa matriser utvecklats och testats. I metod utvecklingen har både porösa och icke-porösa membraner använts för provrening och anrikning före slutanalys med atom absorptions spektrometri (både med flamma och grafitugns tekniken) och stripping voltammetri. De metaller In the present thesis, analytical sample pre-treatment methods for the determination of trace metal ions in complex matrices were developed and tested. These methods were based on membrane fractionation, clean-up and enrichment of analytes and applied to the determination of aluminium, cadmium, cobalt, chromium, copper, nickel and lead in biological and environmental samples. In one application d
This chapter explores the connections between the concepts of sustainable urban transformation and the green urban economy, proposes a framework for understanding how these concepts “fit” together, and makes some practical suggestions for local governments (and national and international policy).
This article focuses on experimental studies of self-heating characteristics of wood pellets. Controlled experiments have been conducted in physical scales from 1 dm3 to 4 m3 with wood pellets. Basket tests have been conducted according to the "crossing-point method" to derive kinetic data on the exothermic reactions responsible for self-heating and eventually spontaneous ignition. The kinetic dat
After decades of development of information systems dedicated to health professionals, there is an increasing demand for personalized and non-hospital based care. An especially critical domain is cardiology: almost two third of cardiac deaths occur out of hospital, and victims do not survive long enough to benefit from in-hospital treatments. We need to reduce the time before treatment. But sympto
