This thesis investigates the effectiveness of a water mist fire suppression system in a submarine environment. As a first step in evaluating the viability of such a system aboard SAAB submarines, the water mist was simulated using an Eulerian-Lagrangian multi-phase model in the the commercial software Star CCM+. The CFD simulation results provide a good visualisation of the distribution of the mis

In Lund, a club culture has been evolving among the city's university students, which has had a great importance on the university life. It is not uncommon for students to go out to a nightclub several times a week, particularly to Student Nations clubs. I have therefore chosen to investigate clubculture in Lund university, through participant observation and interviews. I have also decided to

This paper examines the impact of U.S. monetary policy on sovereign bond spreads in emerging market economies under the period of Unconventional Monetary Policy (UMP). Applying a Fixed effects and Pooled Mean Group method on monthly data from 2009-2020 it shows evidence that changes in spreads can be attributed to an elevated probability of emerging markets being unable to repay loans, arising fro

Skadelindringshierarkin är en vanligt föreslagen princip för att minska påverkan på naturkapital inom planprocesser. Skadelindringshierarkin innebär att påverkan på naturliga miljöer i första hand ska undvikas, annars minimeras – och när detta inte är möjligt återställas inom området eller kompenseras enligt en ekvivalens- och närhetsprincip. Beräkningarna kan utföras i en modell som exempelvis GrA commonly proposed principle for reducing impact on natural capital within the planning process is the mitigation hierarchy. The mitigation hierarchy means that impacts should primarily be avoided, otherwise minimized, and when this is not possible - restored or compensated according to an equivalency- and proximity principle. The outcome can be calculated in a model such as the Green Space Facto

Vår hjärna löser beräkningar som tar oss genom livet otroligt energieffektivt; den kör hela dagen runt på ungefär 12 watt. Jämför man med en vanlig dator som kräver ungefär 175 watt så är det inte ens nära[2]. Att uppnå hjärnans energieffektivitet är ett ambitiöst mål för dagens elektronik. Tricket ligger i att efterlikna hjärnans struktur och uppbyggnad med elektroniken. Detta forskningsområde ka

Detta examensarbete undersöker estetiska värden i arkitektur inom ramarna för cirkulär ekonomi och design. Vad som blir värdefullt när ett samhälle skiftar från vår tids globala kapitalism till ett system där evig tillväxt ersätts av ett resilient system som arbetar inom gränserna för planetens resurser. Rapporten undersöker olika källor kopplade till estetiska värden och cirkulär ekonomi och -desThis thesis examines aesthetic values in architecture within the framework of circular economy and design. The objective is to identify what becomes valuable when a society transitions from the current global capitalism to a system where perpetual growth is replaced by a resilient model that operates within the limits of the planet’s resources. The thesis analyzes various sources related to aesthe

Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. Five different hard candy formulations were exposed to an 8-day storage experiment

Using silicon nanowire (NW) arrays for solar energy conversion has gained special interest in the past years especially for their strong light interaction. The application in photocatalysis, however, requires an additional layer of protection for the silicon surface. To that end, silicon NWs with titanium nitride (TiN) coating, which exhibit a much stronger absorption than their uncoated counterpa

This thesis aims to find a design suggestion for the chassis of a new micromobility vehicle developed by the company LEVTEK SWEDEN AB by using a multiple load, compliance based topology optimization. For this purpose, 9 static load cases are suggested, 4 of which have been derived from dynamic scenarios using an equivalent static load inspired approach based on free-body diagrams. The results from

High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical app

Yatsu has both been described as an ‘abusive’ version of the nominaliser mono, as well having properties not shared with mono. In this paper, the Japanese nominaliser yatsu was examined using the written corpus Balanced Corpus of Contemporary Written Japanese (BCCWJ) created by the National Institute for Japanese Language and Linguistics (NINJAL). The research questions were as follows: “To what e

Many of the finalists selected for the NIST post-quantum cryptography project are lattice-based and rely on a Learning With Errors problem (LWE). To solve such a problem, it is possible to implement a primal attack or a dual attack. In this context, Guo and Johansson as well as the MATZOV center have both proposed an improved dual attack against several NIST lattice candidates. The goal of this t

Development is a contentious concept, praised by some for enabling progress and criticised by others for perpetuating global power imbalances. Development assistance tends to strengthen the donor-recipient dependency, which, according to critics, primarily serves the interests of the Global North while neglecting the needs of the Global South. Mainstream market-driven strategies have exacerbated i

The purpose of the paper is to investigate how stakeholder groups perceive the development of sustainability reporting standards by IFRS. The paper uses a mixed method approach. A qualitative content analysis of comment letters on the IFRS’ consultation paper is conducted and data is presented using graphs and percentages. The theoretical framework consists of legitimacy theory, stakeholder theory

High-Level Synthesis(HLS) is a design methodology that enables designers to implement hardware from high-level coding languages, such as C, C++, or System C. It provides designers with the ability to convey their design at a higher level of abstraction, which allows more emphasis on an algorithm and functional aspects of design instead on low-level hardware details. As precise control of signal ti

The aim of this master’s thesis is to contribute to a deeper understanding of the concept of representation in relation to personal archives. By examining how archivists understand and relate to the concept of representation in their professional role as well as in their work with personal archives, the intention is to clarify the practical implications of the concept. Empirical data has been gath

Firstly, this thesis determines the benefits and drawbacks of and the barriers to the implementation of Cloud Manufacturing. Secondly, five interviews were conducted with two companies that had begun implementing Cloud Manufacturing within their organizations. Lastly, Cloud Manufacturing was

Given the fact that rape is difficult to prove in court and trials primarily are based on the defendant’s word against the plaintiff’s, it becomes highly significant to study the narratives about rape presented in criminal trials. This thesis is an ethnographic-inspired study conduct-ed in Danish courts from January to May 2023. Observations of court proceedings during rape trials were conducted i

Har du någonsin funderat på varför såpbubblor tar den form de gör? Mer specifikt, tänk dig att du doppar ner ett böjbart ihopknutet snöre i såpa så att ett tunnt lager formas. Om du håller snöret i en cirkel så kommer cirkeln fyllas, det är kanske inget konstigt, men vad händer med såpan om du börjar böja på snöret? Den yta som bildas är ett exempel på vad som i matematiken kallas för en minimal yWe introduce the basic theory of currents as continuous linear functionals on compactly supported smooth differential forms. By using slicing and metric-space-valued functions of bounded variation, we prove that the subspace of integer-multiplicity rectifiable currents with locally finite mass enjoy a certain sequential compactness property. This compactness theorem is then used to prove the exist

This study investigates the policy interpretations of development as a concept in the Czech international development cooperation. The rapid transitional experience of countries in Central and Eastern Europe from aid recipient to aid donor claims to have established a unique type of donor, distinct from other major traditional donors, specifically in regard to their approaches to development.
