The use of solar cells as a solution for different energy harvesting applications has seen a significant growth during the last few years. With recent advances in the power conversion efficiency and manufacturability of organic photovoltaic cells these systems can be made even cheaper and more available for consumers, opening up new ways for solar technology to be implemented into products. This p
The underlying reason for this essay was the current chal-lenges of acquiring and keeping competent personnel within the Swedish health care. The purpose statement was to ana-lyze how managers at a Swedish hospital work with talent management, with the focus being on the terms participat-ion, motivation and communication. This was carried out through a qualitative interview study, based on social
We investigate the problem of risk averse robot path planning using the deep reinforcement learning and distributionally robust optimization perspectives. Our problem formulation involves modelling the robot as a stochastic linear dynamical system, assuming that a collection of process noise samples is available. We cast the risk averse motion planning problem as a Markov decision process and prop
The aim of this study was to find models for turbulent fragmenting forces in the high-pressure homogeniser from data available in Computational Fluid Dynamics (CFD) simulations with Reynolds Averaged Navier Stokes (RANS) turbulence models. In addition to the more common RANS k-epsilon turbulence models, a Multi-scale k-epsilon model was tested since experimental investigations of the geometry impl
The Hollow Rock Shelter site in Western Cape Province, South Africa, was excavated in 1993 and 2008. This study presents new results from a technological analysis of Still Bay points and bifacial flakes from the site. The results show that Still Bay points from the site are standardized tools. The points in the assemblage consist of a complex mixture of whole and fragmented points in all phases of
Aim We explored regional variations in the surgical management of patients with Dupuytren's contracture (DC) in 12 European countries using a surgeon survey and patient chart review. Methods Twelve countries participated: Denmark, Finland, Sweden (Nordic region); Czech Republic, Hungary, Poland (East); France, Germany, the Netherlands, UK (West); Italy, Spain (Mediterranean). For the survey, a ran
In 1996 the European Union and the United Nations Framework Convention on Climate Change (UNFCCC) adopted the 2°C climate target to prevent dangerous climate change and to limit the rise in global mean temperature to 2°C above the preindustrial level. If this is possible to accomplish, with increasing emission of greenhouse gases, is hard to tell. There are today many uncertainties within the conn
Denna uppsats undersöker failing firm-doktrinen ur ett rättsekonomiskt perspektiv och granskar vilka samhällsekonomiska konsekvenser som tillämpandet av doktrinen ger upphov till jämfört med om doktrinen inte tillämpas. För att kunna göra denna undersökning utreder uppsatsen inledningsvis vad failing firm-doktrinen egentligen innebär, när den är tillämplig, vilka krav som uppställs för dess tillämThis paper examines the failing firm doctrine through a law and economics perspective and audits the economic impact of the doctrine. The thesis initially examines the meaning of the failing firm doctrine, when it is applicable, the requirements for its applicability and how it has been addressed in case law. The thesis then turns to examine the socio-economic consequences that application of the
This master’s thesis examines the norm-critical awareness among children librarians in Swedish public libraries and how the practical everyday work with current literature for children function with this awareness. By adopting a norm-critical approach you have the ability to observe the different types of norms that you can find among us and that effects the way we see the world. Some of these nor
Horses have a great social, cultural and economic importance in society and contribute to the open landscape. There are currently more than 360,000 horses in Sweden, which together produce over 2.7 million tons of manure per year. This represents 10% of the total amount of manure from all livestock in the country. Most horses are found in urban or near-urban rural areas, which means that there is
The quality of piped drinking water in Maputo is generally poor and it affects many people, in particular the poor living in areas with inadequate or insufficient water distribution systems. In Mozambique, the chemical disinfectant, Certeza (containing diluted sodium hypochlorite), is used to treat domestic water at the consumers’ end. It is well known that chlorine products used for disinfection
In Sweden, municipalities are key players in the environmental work to achieve the ambitious energy and climate goals that are set. For Sweden to be able to meet the national environmental targets that are set to 2020 requires that all the actors in Sweden cooperate. For citizens, these goals mean that lifestyle changes are required, which includes consumption, transport and the use of resources.
A method for investigating how the ocean surface aects the accuracy of Airborne Lidar Bathymetry surveys, (ALB), due to environmental conditions, was developed. Computer graphic techniques were examined and utilized for construction of realistic ocean surfaces. Wave spectrum models available in the literature describing the wave number composition of ocean surfaces were used in order to be able to
Feedbacks between the terrestrial carbon cycle and the atmosphere have the potential to greatly modify expected rates of future climate change. This makes it all the more urgent to exploit all existing data for the purpose of accurate modelling of the underlying processes. Here we use a Bayesian random sampling method to constrain parameters of the Farquhar model of leaf photosynthesis and a model
Indonesien har ratificerat de viktiga internationella mänskliga rättigheter-traktaten som ålägger stater att eliminera diskriminering av kvinnor – CEDAW, ICCPR och ICESCR. Ändå existerar omfattande diskriminering av kvinnor i landet, underblåst särskilt av lokala regleringar som tillkommit genom den starka regionala autonomin. Dessa regleringar, antagna på provins-, region- eller stadsnivå, bryterIndonesia has ratified the crucial international human rights treaties obligating states to eliminate discrimination against women – the CEDAW, the ICCPR and the ICESCR. Yet discrimination against women exists in Indonesia, especially fuelled by local regulations able to arise due to the country’s strong regional autonomy. Enacted either at province, regency or city level, these regulations contra
Our understanding of the society and the world around us is partly communicated to us through the newsmedia. The language used, both written, oral and images, affects the way that we talk about, understand and act upon certain events. In a newsbroadcast there are several interpretations and representations, all communicated in various forms of language, and this language will in turn be the basis
In this thesis, a novel method for characterizing Permanent Magnet Synchronous Machines(PMSMs) based in the dynamic response of the analyzed motor is evaluated. The most significant motor characteristics -torque, flux and efficiency maps- are computed from the motor voltage, currents and rotor position data sampled during the experiment. This way of obtaining the characteristics of the motor is po
Nowadays consumers are becoming more aware of the environmental impacts caused by their consumption habits. As a result their consumption patterns and information needs have changed. Currently, product-related environmental information for ICT consumer products is not easily available. In addition, the general perception of ICT practitioners is that private consumers are not asking for environment
Bridges are critical assets within transportation networks, and their failure, whether due to accidental actions, extreme environmental events, or localized damage, can lead to consequences that extend far beyond the structure itself. In addition to direct safety implications, bridge failures often result in prolonged traffic disruption, economic losses, and reduced network resilience. As traffic
