Energibehovssimulering, klimatkalkyl och termisk komfort för golvvärme respektive luftvärme i småhus

En stor del av samhällets miljöpåverkan kommer från bygg- och fastighetssektorn. Från årsskiftet 2022 finns det nya krav för nybyggnationer på att en klimatdeklaration ska genomföras för bärande konstruktionsdelar, innerväggar samt klimatskärmar. Kraven kan vara ett startskott för att fler delar i byggnader ska klimatdeklareras. Projekt Villazero, ett småhus som uppförs i Borlänge av Fiskarhedenvi

Reproductive experiences of women with unapproved birth under one child policy in G city in China

In China, after implementing the family planning policy in 1979, a huge group of women with unapproved birth were formed. However, the academic research on them are very limited. For women with unapproved birth, sacrificed the most under this “magical” that eliminated hundreds of millions of people in China, but their reproductive practices and experiences are being neglected and ignored. Focusin

Steel-to-concrete connections in narrow concrete corners

Ett vanligt förekommenade problem vid utformning av stål-och betonganslutningar i hörn är att platsbrist kan ge upphov till anslutningar som är asymmetriskt utformade. De avvikande placeringarna på bultarna medför komplexa beräkningar och skapar ett behov av förenklade modeller vid design. Förenklingen kan leda till skillnader i brottsbeteende mellan designen och den fysiska produkten vilket kan lA commonly occurring problem when designing steel-to-concrete connections in corners with space deficits is the necessity for irregularly placed bolts with regards to design codes. The complexity of the calculations for the irregular placements of bolts generates the need to use simplified models during the design. This simplification could lead to differences between the design and the physical p

The value of visual depiction: A comparison of short-term memory capacity between glyph icons and words

Icons are widely used throughout society; moreover, they play a significant role in computer user interfaces, frequently appearing on websites and applications. In many cases, they are used instead of text labels to make a user interface (UI) more universally understood, among other things. Since icons reside within the UI, they should adhere to UI design principles, such as ”reduce short-term mem

Rheological characterization of typical food products

The projects main goal is to increase the knowledge about food rheology at Tetra Pak and towards its’ customers. Rheology is something that affects us everyday whether we think about it or not. To the texture of the food we eat to the process design and the choice of process equipment. The project focuses on understanding viscosity related data and its importance in calculating process design rela

Relating the Arnoldi approximation to the best Chebyshev approximation of the characteristic polynomial - A study using a complex valued variant of the Remez algorithm

Beräkningar med stora matriser är svåra och långsamma att utföra, även för datorer. Med hjälp av en matrisens egenvärden kan man istället arbeta med dess karaktäristiska polynom, där egenvärdena är nollställen. För mycket stora matriser får detta polynom en hög grad och vi skulle vilja approximera det med ett av lägre grad för att förenkla beräkningarna ytterligare. En populär metod för att göra dThe Remez algorithm is a beautiful algorithm that finds the best approximation to a function by finding points satisfying the alternation condition. In 1987 Ping Tang published his doctoral thesis detailing a version of the Remez algorithm modified for functions of complex values with complex coefficients. He later followed the thesis with an article presenting an algorithm for finding the coeffic

Redesign of a Production Dashboard under Consideration of Lean and Performance Management Aspects - A case study

Purpose – The purpose of this master thesis is to test the applicability of the dashboard development procedure by Vilarinho, Lopes and Sousa (2017) in the application case of a single case study for a redesign of a production dashboard. In doing so a practical new dashboard layout shall be reached, which considers the needs of all dashboard users. Design/methodology/approach – This thesis was co

Forecasting gold returns using principal component analysis from a large number of predictors

Gold is known in the financial world to be an important asset in unstable periods, especially as a hedge against inflation. If the gold price can be forecasted, it will be possible to strategically invest in gold rather than acquire it as a last-minute hedge against economic downturns. Although there are many studies on forecasting, few focus directly on gold returns. This study investigates the

Discipline and Order: Hostile architecture in Copenhagen

Hostile architecture is a tool used to control and regulate behavior, individuals, and groups in public spaces. This research explores the use, purpose, and meaning of hostile architecture in Copenhagen. To explore the phenomenon, I conducted fieldwork and semi-structured interviews. The fieldwork consisted of sensory ethnography within a phenomenological framework of data collection and analysis.

A blessing in disguise? - The effect of COVID-19 restrictions on air pollution in India

The outbreak of COVID-19 plunged the world economy into a pandemic with severe consequences. However, the pandemic may very well have been a blessing in disguise for the mitigation of another killer: ambient air pollution. This study investigates how the COVID-19 lockdown restrictions in India affected the ambient air pollution concentrations in a sample of Indian cities. Based on air pollution da

Cenobiter och människohökar: om översättning av ordlekar i de två svenska versionerna av Henry David Thoreaus Walden

I denna masteruppsats jämförs de två svenska översättningarna av Henry David Thoreaus Walden (1854): Frans G. Bengtssons förstaöversättning från 1924 och Peter Handbergs nyöversättning från 2006. Uppsatsen behandlar översättningen av verkets ordlekar i syfte att utröna hur de två översättarna har hanterat detta humoristiska inslag. I en kvantitativ och en kvalitativ analys undersöks hur översättar

Forecasting Exchange Rate Value-at-Risk and Expected Shortfall: A GARCH-EVT Approach

This thesis aims to investigate the accuracy of Value-at-Risk and Expected Shortfall forecasts of various GARCH-type models based on five currency exchange rate pairs. The GARCH models are employed under different conditional distributional assumptions, and extended using the two-stage Extreme Value Theory (EVT) approach of McNeil and Frey (2000). The forecasts are evaluated through simulation usi

Use of Stochastic Switching in the Training of Binarized Neural Networks

Most prior research into the field of Binarized Neural Networks (BNNs) has been motivated by a desire to optimize Deep Learning computations on traditional hardware. These methods rely on bit-wise operations to drastically decrease computation time, however to address the resulting loss in accuracy it is common practice to reintroduce continuous parameters and train using batch normalization. Here

“It’s still a north to south relationship” - A critical discourse analysis on the power of evaluative research and representations of social change within Voluntary Sustainability Standards

Voluntary Sustainability Standards (VSSs) build on market-based governance mechanisms to create fairer and more equitable terms of trade within smallholder-dominated agricultural value chains. Various frameworks and theoretical approaches have arisen to assess social impacts generated through VSSs; however, the findings are scattered and inconsistent. This thesis aims to contribute to a more nuanc

The portrayal of class and social mobility in Charles Dickens’ Great Expectations

Pip’s transformation to become a gentleman in manners and behaviour in Charles Dickens’ Great Expectations illustrates the difference and importance of class in the Victorian society. Through an unknown benefactor, Pip makes a journey from working-class blacksmith apprenticeship in the countryside to gentleman life in the upper-middle class London, with access to economic, cultural and social capi

Bose-Einstein Condensate Jets from Different Traps

This thesis presents a numerical study of the emission of jets by a trapped Bose-Einstein Condensate (BEC). The Gross-Pitaevskii equation is used for the simulation of this phenomenon. When the scattering length of a trapped BEC is periodically modulated it emits jets of matter. We study how the pattern of these emitted jets changes when a BEC is trapped in a circular trap, an equilateral triangul
