This master's thesis explores the improvement of loudspeaker characteristics by using digital signal processing. The main aim of the thesis is to improve the overall audio quality with regards to limited processing power and power supply. Improving the audio quality is important since the vast expansion of the usage of loudspeakers has led to demands on cost, size and design choices all leadin
I vårdnad, boende och umgängesmål ska domstolen ta hänsyn till barnets vilja, som ett led i bedömningen av barnets bästa. Bedömningen försvåras dock ibland av att barn uttrycker sig på ett sätt som egentligen inte representerar deras verkliga vilja. Vad de uttrycker är istället ett resultat av påverkan från en förälder. Att barn i viss mån påverkas av sina föräldrar när de separerar är oundvikligt
Mer än 10% av Sveriges befolkning lider av någon fobi och detta projekt studerar möjligheten att lindra akrofobi (höjdskräck) med hjälp av virtual reality (VR). Arbetets syfte är därför att undersöka hur man på bästa sätt kan lindra akrofobi med hjälp av VR. Frågeställningarna som skulle besvaras var: ”Kan man med hjälp av enbart visuell och auditiv feedback skapa en trovärdig miljö för att lindra

Spiideo's solution is sports video recording made easy, caputuring every moment of practice and competition. The Spiideo system is built around three main components; intelligent 4K video cameras, a cloud server and an app. The solution can bring insights and boost performance of athletes and coaches in almost any sport. Among those behind the technology, developed in cooperation with Axis Commun

This thesis examines the effect of water quality, habitat and species interactions on the occurrence and abundance of stream fishes in southern Sweden. I found that improvements in water quality between the 1960s and 1990s have led to recolonization of streams by brown trout (Salmo trutta L.), stone loach (Barbatula barbatula L.) and eel (Anguilla anguilla L.). The response was greatest for brown
Nitrogenase is the only enzyme that can cleave the strong triple bond inN2. The active site contains a complicated MoFe7S9C cluster. It is believed that itneeds to accept four protons and electrons, forming the E4 state, before it can bind N2.However, there is no consensus on the atomic structure of the E4 state. Experimentalstudies indicate that it should contain two hydride ions bridging two pai
Background Providing high quality nursing care for patients with malignancies is complex and driven by many factors. Many of the associations between nursing care quality, trust, health status and individualized care remain obscure. Objective To empirically test a model of association linking hospitalized cancer patients’ health status, nursing care quality, perceived individuality in care and tru
Gross primary production (GPP) of the vegetation is the largest carbon exchange process of the global carbon cycle. Currently, within satellite-based remote sensing, GPP is generally modelled using linear light use efficiency models where GPP is related to photosynthetically active radiation absorbed by the green vegetation (APAR). These models work well on moderate to low spatiotemporal averaging
Northern ecosystems, encompassing boreal forests, tundra, and permafrost areas, are increasingly affected by the amplified impacts of climate change. These ecosystems play a crucial role in determining the global carbon budget. To improve our understanding of carbon uptake in these regions, we evaluate the effectiveness of employing the physically-based Plant Phenology Index (PPI) to estimate gros
Dune slacks are biodiverse seasonal wetlands within sand dune systems, strongly influenced by the dynamics of the local groundwater regime. Future climate predictions indicate strong adverse impact on the hydrology and therefore ecology of these wetland ecosystems. In this study we aimed to find the most appropriate hydrological and ecological indicators to summarise dune slack plant community res
Background: A wrist-worn wearable device for acquiring limb and chest ECG leads (wECG) may constitute a promising approach to detection of acute myocardial infarction (AMI). However, it remains to be demonstrated whether the information conveyed by the wECG is sufficient for AMI detection. Objective: To explore explainable machine learning models for detecting AMI using the wECG. Methods: Two type
The Veiki moraine in northern Sweden, a geomorphologically distinct landscape of ice-walled lake plains, has been interpreted to represent the former margin of an intermediate-sized pre–Last Glacial Maximum (LGM) Fennoscandian ice sheet, but its age is debated as either marine isotope stage (MIS) 5c or MIS 3. We have applied optically stimulated luminescence (OSL) and radiocarbon dating to four si
Motivation: Comparisons of microbiome communities across populations are often based on pairwise distance measures (beta-diversity). Standard analyses (principal coordinate plots, permutation tests, kernel methods) require access to primary data if another investigator wants to add or compare independent data. We propose using standard reference measurements to simplify microbiome beta-diversity a
Estimates of relative pollen productivity (RPP) represent key input parameters for model-based quantitative reconstructions of past vegetation cover. In this study, we provide the first RPP estimates for 13 taxa from the forest steppe ecoregion in southeastern Romania (southeastern Europe). We used modern pollen assemblages from 26 points together with vegetation surveys and mapping, covering a 1.
