Optimization problems occur in many areas in science and engineering. When the optimization problem at hand is of large-scale, the computational cost of the optimization algorithm is a main concern. First-order optimization algorithms—in which updates are performed using only gradient or subgradient of the objective function—have low per-iteration computational cost, which make them suitable for t

This study addresses the role of natural hazard insurance in two European countries with different insurance markets and socioeconomic conditions: Sweden and Portugal. The analyses were conducted at the national, regional (Southern Sweden and Lisbon Metropolitan Area - LMA), and local (Malmö and Lisbon cities) scales. Most damage caused by weather and climate-related (WCR) hazards during the 1980-

BACKGROUND: Pyogenic liver abscess (PLA) is a rare but potentially life-threatening disease, and estimates suggest a gradual increase in the incidence during the last decades. The primary aim of this study was to report the incidence, trend and aetiology of PLA during a decade in Southern Sweden.METHODS: This was a population-based observational cohort study between 2011 and 2020 in Skåne, Souther

Experimentell uppställning för mekanisk prövning av hälsenor ”Aj!” Så kan det låta när du skadar din hälsena. Hälsenan är en av de starkaste senorna i kroppen och också den som oftast skadas. Skador på hälsenan kan uppkomma till följd av plötsliga rörelser men även vid repetitiv överansträngning under en längre tid. I värsta fall kan senan gå av helt och hållet. För att kunna förebygga och behandTendons connect muscle to bone and assist in joint motion. To be able to do this, they must withstand large forces and be able to alter their structure under load. If a tendon experiences too high or sudden forces, it will start to tear and eventually rupture. To examine how this happens and how the tendon behaves before rupture, mechanical testing is done. This study focuses on how to combine mec

Voluntary Carbon Markets (VCM) have emerged with the intention of supporting decarbonisation and carbon dioxide removal solutions around the world. However, and despite a rapid growth, the motivations and preferences of the demand side to engage in with the VCM have not been thoroughly studied before. Iceland, the focus of this thesis, exemplifies this trend. To address this knowledge gap, this th

Genom att observera och intervjua invånarna i Lund, kan man erhålla mycket information om historien och infrastrukturen för staden. Detta tyder på en särskilt självklar princip; om man studerar de mindre beståndsdelarna av ett system, så kan man erhålla egenskaper som är gällande för systemet i helhet. Detta är precis vad dagens astronomer utnyttjar för att lära sig mera om vårt universum. De minsThe first part of this thesis deals with the dynamical estimation of the Oort constants using proper motions and parallaxes provided from the Gaia-DR1 TGAS catalogue. The photometric information was provided by the 2MASS catalogue. The Oort constants calculated from the TGAS catalogue are compared to those obtained from the original Hipparcos catalogue in order to attempt to estimate how well Gaia

Uganda has experienced extreme weather for example droughts and flooding for many years resulting from rainfall deficits and variability. With the increased manifestation of negative effects related to climate change and global warming, this challenge is becoming greater and greater. And with increased public awareness about disasters and disaster risks, communities are ceasing to portray droughts

Scientific summary Urban growth and recent development removes the natural land cover and replaces it with a new cover of manmade features (e.g. buildings, streets, industrial areas, commercial complexes etc.). Accordingly, the local climate of these cites has been modified by new land use and land cover alterations which has created the Urban Heat Island (UHI) phenomenon. Erbil City in northern I

Urbanization and Density in Zanzibar - Recommendations for Sustainable Urban Development from Swahili houses to low-rise multi-storey houses. The rapid urbanization process in Africa is a major challenge for politicians, urban planners and society in general. The archipelago of Zanzibar in Tanzania is in the middle of this process. Traditionally, low and middle income families live in Swahili hous

With the announcement of Energy Revolution by the government of China, and the support of policies and investments in clean and renewable energy, electric vehicles and bikes have recently been developed rapidly, which has promoted the prosperity of lead-acid battery industry and made China now the world’s leading producer, refiner, and consumer of lead-acid battery technology. However, this has cr

Fastighetsskatt är en löpande beskattning av fastigheter. I Sverige baseras fastighetsskatten på fastighetens värde och ska betalas av ägaren årligen. Väldigt liten hänsyn tas till den skattskyldiges inkomstförhållanden. Fastighetsskatten har i perioder varit väldigt omdebatterad och det är många som har haft synpunkter på hur den är utformad och på om skatten borde existera överhuvudtaget. År 20The Swedish property tax saw a reform in 2008. The former system with a state property tax (1 percent of the property’s tax value) on housing was replaced by a local real estate fee (0.75 percent of the property's tax value or a maximum of 6000 SEK). Furthermore, the local real estate fee is, in contrast to the property tax, limited in size and 25 percent lower for properties that do not reach

The low-energy region of the intermolecular potential energy hypersurface (PES) of the ammonia dimer was studied at the level of second-order Moller-Plesset perturbation theory (MP2) using a very large basis set. Individual minima were located on the PES employing the counterpoise (CP) correction to account for the basis set superposition error (BSSE). Apart from these canonical MP2 calculations l

The main purpose of the pursued research is to increase knowledge of the effects of knots in structural timber so that characteristics of weaker timber may be determined and applied to improve current grading techniques. In the process, a three-dimensional fiber paradigm was established, which describes variations of local principle material axes in timber containing knots. The adaptability of the

Salvage hypospadias surgery is performed after failed primary reconstruction. Several treatment strategies have been suggested, all with pros and cons. The aim of this study was to evaluate our treatment algorithm for primary hypospadias repair applied to secondary cases in which a salvage procedure is indicated and, most importantly, local tissue is present. The algorithm was applied to 36 consec

Background and purpose — Impaction bone grafting (IBG) in revision hip surgery is an established method in restoring bone stock deficiencies. We hypothesized that local treatment of the morsellized allograft with a bisphosphonate in cemented revision would, in addition to increased bone density, also reduce the early migration of the cup as measured by radiostereometry (RSA). Patients and methods

The past 23 years of post-socialist restructuring of health system funding and management patterns has brought many changes to small Balkan markets, putting them under increasing pressure to keep pace with advancing globalization. Socioeconomic inequalities in healthcare access are still growing across the region. This uneven development is marked by the substantial difficulties encountered by loc
