Due to the small characteristic molecular size of hydrogen, small leaks are more common in hydrogen systems compared to similar systems with hydrocarbons. This, together with the high reactivity, makes an efficient ventilation system very important in hydrogen applications. There are several models available for ventilation sizing that are based on either a well-mixed assumption or a fully stratifDue to the small characteristic molecular size of hydrogen, small leaks are more common in hydrogen systems compared to similar systems with hydrocarbons.

Artificial Intelligence has existed for many years and keeps developing. AI has become better at generating new works, for example music, which raises a question of whether AI can potentially infringe on copyright. This thesis examines the legal framework regarding copyright and AI and whether AI used in music can constitute a copyright infringement. The question that is focused on is “To what ext

Staphylococcus aureus, strain Cowan I, has been shown to contain a cell‐wall substance, protein A, which combines with the Fc part of IgG in most mammalian species. Since the blocking activity of sera from tumor‐bearing individuals has previously been found to be associated with 7S immunoglobulins, it was investigated whether Cowan I could absorb out the blocking activity of sera from rats carryin

Today fingerprint matching software is widely used in applications such as mobile phones. Software for enrollment and verification of fingerprints is usually designed to work for "good" fingerprints, meaning that the fingerprint matching algorithms use minutiae locations. When such information is scarce due to scars, blisters or other damages, the algorithms do not work very well. In thi

Background: Preeclampsia is a leading cause of maternal and fetal mortality. Although antenatal care can identify women at risk, limited research has explored women's experiences with preeclampsia despite itssignificant impact.Aim: This thesis aims to enhance the understanding of women's experiences with preeclampsia in order toimprove clinical care, support, and mental health outcomes. This inclu

Collaboration between academia and society has become a key priority for many higher education institutions (HEIs). In Sweden, this is partly driven by political calls to secure the long-term provision of knowledge, innovation and competitiveness. At the system and institutional level, responses to this are reflected in governance structures and strategic documents.

Non-Orthogonal Multiple Access (NOMA) for a multi-user single- input single-output (SISO) setup is studied in the power and the frequency domains simultaneously. The problem of sum-bandwidth minimization under perfect channel state information is solved for various combinations of rate requirements and user pairings. In this process, an iterative Tabu-search based algorithm is applied to avoid an

The theory of the Investment Development Path (IDP) by John H. Dunning suggests that as a country develops, its composition of inward and outward foreign direct investment change both regarding to quantity and type of investment. The theory consists of 5 stages a country passes as its OLI-advantages develop. In this paper we have applied the theory of the IDP on the case of Brazil in order to eval

In today society people live longer and along with the rising life expectancy chronic diseases, like dementia, will become more common. The demand on more and better assistive technology, technology that ease the everyday life for the persons with dementia, will increase. The assistive technology currently recommended by occupational therapists are mainly low-technological solutions. There exist

Although deep learning has made advances in a plethora of fields, ranging from financial analysis to image classification, it has some shortcomings for cases of limited data and complex models. In these cases the networks tend to be overconfident in their prediction even when erroneous - something that exposes its applications to risk. One way to incorporate an uncertainty measure is to let the ne

The estimated number of children who are utilised as child soldiers all over the world is 250,000 today. Based on the Coalition to Stop the Use of Child Soldiers research children were used in armed conflicts in 20 countries from 2004-2007. One of the most prominent nations involving the use of child soldiers is the Democratic Republic of the Congo. It is estimated, that 40% of them are girls, who

Despite the importance of the UK in meat production in the EU and its increasing population, there is still a lack of rapid, accurate and inexpensive technique to determine an appropriate durability for meat products. As the population increases, the demand for safe and of satisfactory food by both consumers and government raises, so as the demand for a favourable tool to ensure the safety of food

According to Sec. 23(3), of the Danish Copyright Act copies of works of art which have been transferred to others by the author, may be used in newspapers, periodicals, films and TV, when the use is of subordinate purpose in the said context. The use of a work of art, here in the form of applied art, by reproduction on packaging for foods and supermarket leaflets from convenience stores falls outs

Catalytic processes have tremendous importance in our everyday life. Most chemicals, pharmaceuticals, plastics etc. are, in fact, produced with the help of catalysts. What is probably even more important is that the toxic wastes produced in great amounts by modern factories and plants are recycled or transformed into less poisonous substances by means of catalytic units. One example from our everyThe present work is devoted to atomic scale structural studies of the surfaces of model heterogeneous catalysts relevant to oxidation reactions. A novel approach using high-energy surface X-ray diffraction combined with mass-spectrometry measurements is employed to perform in situ structural characterization of Pd(100) and Pd(553) single crystal surfaces acting as catalysts in the process of CO ox

Drones have been used by the military since mid-1970 but the development of autonomous systems from the turn of the millennium and onward has opened the area of UAV to civil service and the public immensely. Today UAV technology saves lives in Search And Rescue operations, complements and supports full scale vehicles at the Police force and assists in surveys and documentation of ground and forest
