Assessment of the fire behaviour of sandwich panels is continuously under discussion. The fire behaviour of these panels is a combination of material characteristics such as the core material and mechanical behaviour of the panels such as joints, dilations etc. The use of small or intermediate scale tests can be questioned for such types of products. Within the proposed European product standard
We present a high-resolution ( R= 75 000, S/ N ) spectroscopic analysis of the bright ( V= 11.7), extreme halo giant CS 31082-001([Fe/H] = -2.9), obtained in an ESO-VLT Large Programme dedicated to very metal-poor stars. We find CS 31082-001 to be extremely rich in r-process elements, comparable in this respect only to the similarly metal-poor, but carbon-enriched, giant CS 22892-052. As a result
Electromagnetic compatibility (EMC) is a vital part of product development, and understanding the sources and causes of the emissions can facilitate tremendously in reaching compliance requirements and reduce the work needed for troubleshooting. At Axis Communications, where this thesis has taken place, the knowledge of EMC is an important part of their work and they aspire to improve further. Thi
Concerto for Double Bass and Orchestra by Eduard Tubin is considered to be one of the most challenging pieces of the double bass repertoire as it is known to be a physically demanding work. It was written for double bass player Ludvig Juht who was a physically big built man and welcomed the technical challenges. This thesis aims to analyze these challenges of the piece for a player with smaller ph
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
This study aims to identify the most cost-effective and environmentally friendly retrofit solutions for enhancing the energy efficiency of second homes in Sweden. Second homes, often used intermittently throughout the year, represent a significant portion of residential energy use and carbon emissions. Therefore, optimizing energy consumption in these homes is critical for achieving national and g
Soil moisture (SM) is an essential climate variable that controls fundamental hydrological and climatic processes. Soil moisture products derived from microwave remote sensing often provide measurements at low spatial resolution and incomplete temporal records. This thesis presents a novel method for estimation soil moisture at both high spatial and temporal resolution by using a deep learning rec
Microgrids and distributed renewable energy have the potential to facilitate management and adaptation for climate change. While research on microgrids has been developing for the past decades, further studies are necessary to expand on business models and scenarios which lead to their successful commercialization and implementation. This study applied the business model canvas as an analytical fr
Electric cars are by many considered a sustainable solution to the ever-growing demand for road vehicles and fuel. The transportation sector is responsible for almost a third of the total greenhouse gas emissions globally and approximately 80% of these emissions can be attributed to road vehicles. Thus, there is an urgent need for a shift away from fossil fuels in the sector. While the consumer in
As Special Purpose Acquisition Companies (SPACs) are becoming the increasingly popular method of taking a company public, the lack of research on abnormal returns for this asset class since its introduction to the major exchanges validates a reason to expand the investigation. This thesis examines the potential abnormal returns found in different stages of recent SPACs lifecycle, dividing the SPAC
Derivative models often come in the form of stochastic differential equations. From these equations a partial differential equation (PDE) can be derived. By discretizing the PDE the numerical solution is obtained on a form where the value of the derivative can be seen as a probabilistic weighting of future values. These probabilities can be used to simulate trajectories of the under- lying assets.
Rätten till medborgarskap kodifierad i artikel 15 i FN:s declaration om de mänskliga rättigheterna tolkas som rätten att ha rättigheter. Genom medborgarskap säkras tillgång till grundläggande mänskliga rättigheter. Personer som inte betraktas som medborgare i någon stat enligt dess lagar är de jure statslösa. Åtnjutandet av mänskliga rättigheter för de jure statslösa är följaktligen begränsad. FThe right to nationality codified in article 15 of the Universal Declaration of Human Rights is understood as the right to have rights. By possessing nationality, access to fundamental human rights is ensured. A person who is not considered a national of any state according to its laws is de jure stateless. De jure stateless persons are consequently impeded to enjoy such human rights. As of today
This study aims to explore the influence that stigma and beliefs have on the disability-related help-seeking for children with intellectual disabilities in Kampala, Uganda. These children are regarded as one of the most neglected groups in developing countries, where access to rehabilitation services frequently is restricted starkly, and beliefs and stigma are believed to interfere in the process
The purpose of this study is to conceptualize the practice of knowledge rhetoric in knowledge-intensive firms (KIFs). The methodology applied to this qualitative study is based on the principles of a social constructivist paradigm. Document analysis in turn, with a multi-leveled Key Words In Context (KWIC) technique, was applied in analyzing the source material. The source material consists of the
GIS Section of Street and Park department of Malmö Municipality continuously receives new spatial data from different contractors that need to be saved to the GIS section traffic database. Due to spatial relationships and daily updates of traffic database, it is evident that the traffic database requires more consistency and integration in an automatic way. Since there is a spatial and conceptual
Anthropogenic use of nitrogen and phosphorus causes a risk to aquatic ecosystems and hence the livelihood of humans. To tackle this issue, the European Union have imposed environmental obligations on its member states to higher the quality of the aquatic environment. As a member state, Denmark is partly fulfilling these objectives by re-creating wetlands in the landscape, which retain and remove n
Gas cooling is a technique used within the fire service to reduce the risks of the hot gaseous layer and create a better visibility. It is achieved by applying water into the gaseous layer. Successfully performing or implementing this technique is something that has not yet been accomplished in every brigade. This work has been focused on different parameters that affect gas cooling and is studie
Recent global warming trends, particularly in the arctic regions and Himalayas are modifying forest structure and function, notably biogeographical changes in tree species distribution together with alteration in Net Primary Production (NPP), Leaf Area Index (LAI) and Carbon biomass. These alterations are most pronounced in mountain environments, carrying significant impacts on woody species which
After the failure to respond adequately to the changing patterns of conflict and violence after the end of the Cold War, human security was popularized in the 1990s as an alternative concept to security more suitable to face threats to individual security. Ever since, the question about what human security should entail has seen much discussion. This paper examines the different discourses which i
