Näringsämnesretention i fyra nyanlagda våtmarker i Falkenbergs Kommun
This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.
Den olfaktoriska l?sningen. Lukt i Sara Stridsbergs Happy Sally
This essay examines the olfactory reading as a possible way to make sense of a fragmented novel, in this case Sara Stridsberg?s debut Happy Sally (2004). Through close reading, the essay identifies the source of the smells, who perceives it, and how this is portrayed in the text. The smell?s position in the text is understood in relation to Maurice Merleau-Ponty?s phenomenology, where the body, as created in the literary text, is considered as a source of knowledge.

Modeling of Natural Human ? Robot Encounters
Studiens syfte är att belysa teknikens mångfald samt att analysera hur man kan väcka barns intresse för teknik och hur man kan skapa inlärningstillfällen i förskolan. Undersökningen bygger på en litteraturstudie. Forskning och teknikprojekt har studerats. Resultatet visar att framför allt förebilder, teknikmedvetenhet och undervisningsmetod har påverkan på barns teknikintresse. Vidare behöver barn komma i kontakt med gammal, enkel och synlig teknik, vilket man kan utgå ifrån vid planering av förskoleverksamheten i teknik.
Kinematisk och dynamisk modellering av den haptiska enheten TAU i sex frihetsgrader
The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.
Hantering av QoS i Distribuerade MPEG-videosystem
With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.
Konstruktion av turbinmodell för kaplanturbiner
Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören
The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.
The Sound of Skepticism Analyzing Climate Change Denial in Swedish Podcasts and YouTube Channels
This study explores Sweden's climate change denial by analyzing the spoken-word discourse of
its countermovement, focusing on digital media content from Swedish parliament member Elsa
Widding with an aim to provide empirical insights into the discourse of Sweden's Climate
Change Countermovement (CCCM). Questions guiding this study are: What are the most
prevalent topics and themes related to climate change denial and skepticism? How do they align
with established categories of climate change denial, shaping the overall narrative? What
mobilizing ideas and meanings are present, how are they shaped, and how do they contribute to
the movement's goals? The material consists of Elsa Widding's complete audio-based
"movement texts'' from 2019-2023, including YouTube content, podcasts, and appearances on
Riks, totaling over 2000 minutes of audio transcribed into text via AI technology.
Methodologically, this study adopts a mixed-method approach which blends computational
pattern detection, topic modeling, clustering, and spatial relationship mapping techniques, along
with qualitative content and framing analysis. Theoretically, the study employs a perspective
which uses epistemic and response skepticism to examine climate change denial, viewing it
through the lens of countermovements and social movement framing. The study's main
contribution lies in the enablement of comprehensive analysis of a large audio-based dataset,
achieved by leveraging recent AI advancements for reliable audio-to-text conversion combined
with topic modeling.
Dynamisk kunskapsorganisation: teoretisk ansats och implementering
Knowledge organization is perceived as a central, constituting activity defining the notion of libraries. Critique calling for a new theoretical foundation voiced by active researchers within library and information science concerning the current knowledge organization has been utilized as a point of departure. Specifications concerning a new theoretical foundation implied by these critiques are considered within this thesis and theory found in The Order of Things by Michel Foucault proposed as an alternative theory for understanding knowledge organization as a human science where meaning, value and representation, by which the ordering of things is possible, is acknowledged as a result of human activity and history. Thus meaning, value and representation must be perceived as dynamic. An example of implementation of the proposed theory has been achieved by the use of bibliometrics.
