Accurate and efficient evaluation of the stored energy is essential for Q-factors, physical bounds, and antenna current optimization. Here, it is shown that the stored energy can be estimated from quadratic forms based on a state-space representation derived from the electric and magnetic field integral equations. The derived expressions are valid for small antennas embedded in temporally dispersi
The way we frame a given problem structures the content that is brought into focus and thus the kinds of practical steps seen as necessary to alleviate it. In this article, I interrogate two competing partial framings implicated in ongoing controversy over mangrove destruction in Vikhroli East, Mumbai, which have precluded integrated conservation and development. I interrogate the competing frames
Popular Abstract in Swedish Luftföroreningar har i många studier visat sig skada vår hälsa. Även om risken för den enskilda individen kan vara relativt liten så kan omfattningen av hälsoeffekterna bli stora eftersom det är så många som exponeras. Tidigare har man huvudsakligen sett effekter på andningsorganen men under de senare åren har man även börjat se effekter som sträcker sig bortom våra andWe had in the present thesis the unique possibility to use, in a socio-economically relatively homogenous population, high quality registry information on a population-based birth cohort (84 039 births during the period 1999-2005) in Scania (Skåne), the most Southern county of Sweden. The aim of the thesis was to investigate whether exposure to air pollution, in an area of low-levels exposures, du
Popular Abstract in Swedish I avhandlingen presenteras nya teoretiska och experimentella metoder för att analysera spridning av elektromagnetiska vågor, framförallt med fokus på antenner och trådlös kommunikation. Oavsett det handlar om radio- och TV-sändningar, mobiltelefoni, trådlösa datornätverk, eller radar, så är antenner oumbärliga; de är nämligen länken mellan de elektromagnetiska vågorna oSum rules and physical limitations within electromagnetic theory and antenna theory have received significant attention in the last few years. However, the derivations are often relying on application specific and sometimes unsupported assumptions, and therefore a mathematically rigorous and generally applicable approach seems timely. Such an approach is presented in this thesis, along with exampl
The aim of this study was to determine effects on methane potential and overall sludge quality from two different sludge pre-treatment technologies (ozonation high/low dosage and thermal treatment 55/70 degrees C). In general both treatments produced increased methane potential. Thermal treatment resulted in higher chemical oxygen demand (COD)-solubilisation, while the highest volatile fatty acids
Context. Metal-rich globular clusters provide important tracers of the formation of our Galaxy. Moreover, and not less important, they are very important calibrators for the derivation of properties of extra-galactic metal-rich stellar populations. Nonetheless, only a few of the metal-rich globular clusters in the Milky Way have been studied using high-resolution stellar spectra to derive elementa
Den ryska invasionen av Ukraina har orsakat ofattbart mänskligt lidande och har destabiliserat den europeiska säkerhetsordningen. I gengäld har världsledare och internationella organisationer krävt att den ryska aggressionen beivras. Den rättsvetenskapliga debatten om lämpliga åtgärder för att säkerställa straffrättsligt ansvar för aggressionsbrottet har emellertid uppvisat stor oenighet bland forThe Russian invasion of Ukraine has brought immense suffering to the Ukrainian people and has destabilised the European security order. In response, world leaders and international organisations have called for the prosecution of the Russian aggression. However, the scholarly debate on the appropriate measures to ensure criminal accountability for the crime of aggression has demonstrated widesprea
Interpreting EEG measurements is of great relevance, both for developing underlying neuroscientific theory and improving existing applications. In this study, two networks with different approaches to time-frequency analysis and feature selection are compared on simulated and real data for semantic and emotional perception. The first network uses the Morlet wavelet transform to achieve adaptable f

As commodities are becoming more popular and accessible assets for speculative and hedging purposes, the limited research regarding risk management for said asset-class justifies further contribution to the deficient output. Many previous studies have highlighted the extraordinary high volatility, with non-linear and clustering characteristics associated with commodities. Hence, incorporating vola
In the face of climate change wind energy plays an increasing role in Norway. The construction of new wind farms causes opposition and conflicts with, among others, Sámi reindeer herders who are concerned about losing their pastures. By using Schlosberg’s (2004) environmental justice framework, I explore the justice implications of wind energy with regard to Sámi reindeer husbandry in the case of
A joint research between Lund University and Chalmers Competence Centre for Catalysis have shown promising results for a Rh-based catalyst for CO2 hydrogenation catalytic applications. The original catalyst consisted of a dispersion of nanoparticles onto a porous 3D oxide network. To gain a deeper understanding of the catalyst, a surface science study is necessary, but it is impossible to perform
Bakgrund: Psykisk ohälsa bland ungdomar och unga vuxna har ökat och kommer sannolikt att fortsätta öka på sikt. Depression och ångestsyndrom är bland de vanligaste orsakerna till psykisk ohälsa världen över. Arbetsterapeuter besitter en avgörande kompetens inom aktivitet och hälsa. Denna kompetens kan vara behjälplig för ungdomar och unga vuxna med depression och ångestsyndrom. Syfte: Att kartläggBackground: Mental illness among youth and young adults has increased and will likely continue to increase in the long term. Depression and anxiety disorders are among the most common causes of mental illness worldwide. Occupational therapists possess competence in activity and health. This competence can be helpful for adolescents and young adults with depression and anxiety disorders. Aim: To ov
To determine whether adjuvant tamoxifen treatment for breast cancer (BC) is associated with reduced contralateral breast cancer (CBC) risk for BRCA1 and/or BRCA2 mutation carriers.
Drinking water disinfection byproducts have been associated with an increased risk for congenital defects including cardiac defects. Using Swedish health registers linked to information on municipal drinking water composition, individual data on drinking water characteristics were obtained for 58,669 women. Among the infants born, 753 had a cardiac defect. The risk for a cardiac defect was determi
The expected annual cost (in the year 2000 prices) for a 30-year-old patient with average individual and treatment characteristics for on-demand EUR 51 832 (95% CI: 44 324-59 341) and for prophylaxis EUR 146 118 (95% CI: 129 965-162 271), was obtained from panel-data analysis of an 11-year retrospective panel of 156 patients with severe haemophilia in Norway and Sweden. Costs included haemophilia-
Few studies have been made on challenges and enablers with implementing Stage-Gate processes in mature organizations. The aim with this thesis, is therefore to fill the gaps in knowledge within implementation of Stage-Gate processes and additionally describe the general challenges and enablers with Stage-Gate processes for R&D and innovation projects.
