När en ny bil skall designas är det viktigt att kunna förutse vissa fenomen innan en fysisk prototyp finns tillgänglig. Ljudet som orsakas av vägen är ett av dessa fenomen. På grund av känsligheten och komplexiteten i metoderna som används idag vore det intressant ifall man kan använda något enkelt mått för att få en känsla för detta fenomen i en tidig konceptutvecklingsfas. Frågan blir då, vilketThe noise, vibration and harshness (NVH) and body dynamic performance of automotive vehicles is highly dependent of the components included in the body structure and compartment, since they add mass, stiffness and damping to the overall structure. Today, the noise levels in the compartment are predicted using complex and detailed computational models during both early and late stages of the vehicl
Nya system skapar svårigheter då man inte kan använda redan etablerade metaforer, designer eller sätt att beskriva och prata om systemet. Detta arbetet ämnar att underlätta arbetet med sådana system genom att erbjuda designprinciper och metodiker för att jobba med dem och undersöka vilka svårigheter man behöver vara medveten om. För att forma och testa nya designprinciper och metodiker så genomföOne of the difficulties in designing new products is the absence of already tried metaphors, designs or ways to talk about the system. This thesis focuses on methods and practises one could potentially use when designing something new - and if there are any challenges one need to aware of as a designer of such a system. In order to devise, and test, these practices and methods, an example system
The aim of the study at had was to explore the potential of Natural Capital Accounting (NCA) to integrate environment into business decision-making. In order to fulfill the aim, the research was split into three main parts. First, the existing views on what constitutes NCA were reviewed through a literature analysis of grey literature, and the working definition established. The study found that t
With the climate change and urbanization process, the frequency of the urban flooding’s occurrence has increased in the recent years. It brings great economic losses to the cities, especially to the basements of individual properties. Low Impact Development (LID), which currently advocated by more city planners for managing stormwater, is considered as a more sustainable way to mitigate urban floo
The focus of this work has been to implement a generic netlist reduction engine to speed up circuit simulations. The netlist reduction techniques are further optimized for Static Random-Access Memory (SRAM), wherein we exploit the repetitive pattern of the circuit. There are many driving factors for developing a netlist reduction engine for SRAM simulations. In today's System on Chip (SoC), S
In the midst of a global shift in world politics induced by the rise of emerging powers, the outdated and unequal international financial institutions (IFIs) that were set up after World War II are increasingly being challenged and scrutinized. International actors can use IFIs in numerous ways to enhance their position in the world system. For instance, they can be used as a vehicle to launder st
There is an ongoing discussion in information retrieval research regarding the merits of subject indexing with controlled vocabularies as opposed to relying on free-text descriptions. Earlier research has compared subject headings with other metadata, such as document titles or tables of contents, to determine the relative value of subject headings as subject access points in an information search
Allting är uppbyggt av atomer, inte bara träd, djur eller bläcket i dessa bokstäver, utan även astronomiska objekt så som stjärnor och planeter. Stjärnor är i princip extremt varma och kompakta moln av atomer, som skickar ut ljus i alla riktningar. Astronomer är intresserade av vilken sammansättning av atomer som bygger upp stjärnor eftersom detta hjälper dem att förstå hur stjärnor och galaxer biStellar abundances are important for understanding the chemical evolution of galaxies and provide us with constraints on stellar evolution and supernova nucleosynthesis. To determine stellar abundances accurately, atomic data is crucial. This data is incomplete for many elements, especially in the infrared region. In particular, hyperfine structure (hfs) data in the near-infrared region is lacking
Highly glazed spaces are continuously increasing in popularity due to architectural attractiveness. However, increased use of glass often jeopardizes thermal comfort in several ways and problem of overheating is one of them. A way to face this problem is to appropriately use solar control mechanisms. However, a proper selection of solar control mechanisms from an early design stage is a complex ta
Vid marktekniska undersökningar i finkorniga jordar är det av stor vikt att korrekt kunna bestämma den odränerade skjuvhållfastheten. Detta görs idag vanligtvis ute i fält med en uppsjö av sonderingsmetoder som ger olika mått på hur fast jorden är. För homogena leror och sand finns det en stadig empirisk grund för hur dessa sonderingsparametrar räknas om till odränerad skjuvhållfasthet, men hur seThe undrained shear strength is a key parameter in the design process of geotechnical structures. One of the most frequently used methods to investigate this parameter is the cone penetration test (CPT). The CPT does not measure the undrained shear strength directly, but instead the resistance that a conic probe encounters as it is pushed into the ground. A calibration factor, the cone factor (Nkt
Around the 150th anniversary in 1998, historical research showed new interest for the wave of revolutions that swept across Europe in 1848. This research focused on providing a new European frame of interpretation for the events in 1848, questioning the exclusive national historiographical traditions of European history, a field of study already formed by the works of Jean-Baptiste Duroselle in 19
BIM, byggnadsinformationsmodellering, är ett arbetssätt som blir allt vanligare. Det innebär att olika objekt bygger upp en övergripande 3D-modell där man kan finna mängder av information om dessa objekt. Ett objekt kan vara allt ifrån en bropelare till en elstolpe. Syftet med denna rapport är att utifrån Trafikverkets roll som beställare undersöka vilka för- och nackdelar det skulle innebära med BIM, Building Information Modeling, is an increasingly common way of working. This means that different objects build up an overall 3D-model where you can find lots of information about these objects. An object can be anything from a bridge pillar to an electric pole. The purpose of this report is to, based on the Swedish Transport Administrations’ as a client, investigate the advantages and disad
Introduction: This study attempts to optimize the choice of stationary phase for the separation of lignosulfonate lignin compounds using supercritical fluid chromatography coupled to mass spectrometry. Background: Lignin is a potential renewable source of phenolic compounds. Lignosulfonate lignins are produced during pulping processes producing very complex mixtures, which are challenging to anal
Coffee production systems are experiencing climate change stress in a multitude of ways. One of the ways in which climate change manifests itself in coffee systems is through the evolution of pest and disease populations. Global coffee production is thereby recognized as vulnerable to climate change, particularly the lives of those that rely on coffee for their livelihoods. Reducing vulnerability
Monapostrukturen ligger i Nampula provinsen i norra Moçambique, och utgör en del av Mocambique bältet. Strukturen är ca 35-40 km i diameter och har en mycket låg topografi. Trots detta syns den väl på satellitbilder och flygfotografier. Relationer mellan samt utbredning av de enskilda bergartsleden är inte helt klarlagd och frågor såsom transportriktning, litostratigrafisk uppdelning samt tektonisThe Monapo Structure is situated in the Nampula Subprovince in northern Moçambique, and makes up a part of the Moçambique Orogenic Belt. It is a 35 x 40 km subcircular structure, with a very flat topography, and it clearly shows up on aerial photos. The regional setting of the Monapo Structure is not yet clearly settled and many questions regarding transportation directions, lithostratigraphic gro
The aim of this research is to study three particle correlations in pseudo-rapidity for the $\Lambda^0$,$\Xi^0$, and $\Omega^-$ hyperons with a focus on their baryon and strangeness quantum numbers. The two primary questions asked are, into which particles are these quantum numbers typically conserved, and what are their correlations in momentum space. The research investigates these problems by e
Sperm whales (Physeter macrocephalus) communicate with one another using an intricate language made up of sequences of clicks. Recent studies have begun to dig deeper into the structure and content of these vocalisations in an effort to detect and extract significant patterns and features. Whether or not the results of such research will eventually allow us to translate sperm whale speech into som
Den 1 juli 2022 trädde en ändring av lagen (1988:254) om förbud beträffande knivar och andra farliga föremål, även kallad knivlagen, i kraft. Denna innebar bl.a. att kvalifikationsgrunder infördes för bedömningen av om ett brott ska rubriceras som grovt, och att straffskalan för grovt brott skärptes till fängelse i lägst sex månader och högst två år. Syftet med den här uppsatsen är att analyseraOn 1 July 2022, the Swedish Act (1988:254) on the Prohibition of Knives and Other Dangerous Objects (the Swedish Knife Act), which criminalizes possession of knives and other dangerous objects in public places, was amended. Through the amendment, four criteria were introduced to the statutory text, which are to be given particular consideration when assessing whether a violation of the law is to b
Sustainability reporting remains a well-established field of research, with many important contributions. Additionally, the public has a growing desire for firms to adopt responsible ESG practices, thus requiring more transparency and accountability. Without the acceptance from the public, the business might face negative consequences. The understanding of how sustainability reporting is disclosed
