This masters thesis handles segmentation of blood vessels in Wistor-rat lungs, scanned by a µm-CT scanner. These scans are very detailed 3D-volumes and have been rescaled to a more manageable size of 1024 × 1024 × 1024 voxels per volume. The main goals of the thesis is to find a more efficient way to perform segmentation in medical images and thus semi-supervised segmentation techniques have been
Gröna områden i städer, så som parker, alléer och trädgårdar, är mycket mer än bara en trevlig och grön kontrast till den gråa stadsmiljön. De bidrar med flera saker vi ofta tar förgivet i Sverige, bland annat frisk luft, skugga under varma sommardagar och platser för lek såväl som avslapp ning. Tillsammans kallas dessa nyttor för ekosystemtjänster, vilka är livsnödvändiga för oss män niskor såvUrban green spaces provide important ecosystem services that support human well-being and climate adaptation in cities. As urbanisation and densification increases, municipalities face chal lenges in promoting and safeguarding these areas. This study investigates the current methods and tools used by municipalities in southern Sweden to assess urban green spaces with regard to ecosystem service
Att skriva SQL-satser för att hämta användardata är ofta en ansträngande uppgift som kräver god kännedom om hur datainsamlingen fungerar, och hur användare interagerar med applikationen. För utvecklare som endast skriver SQL ibland innebär det mycket kontextväxling och tid som går åt till att åter bekanta sig med dataanalyseringsarbetet. För att lösa detta problemet utvecklades en intern AI-agentWriting SQL to extract usage data is a strenuous task that requires extensive knowledge of logging practices and user interactions within an application. For engineers and developers who write SQL only intermittently, the resulting context switching and re-familiarization can consume valuable work hours. To address this challenge, an internal AI agent was developed to transform natural language i
Extending the service life of existing buildings and their components is essential for slowing resource loops in circular construction. While overall building lifespans are relatively well understood, the actual service lives of individual components remain underexplored due to limited empirical data. This study addresses this gap by analyzing and modeling building component lifespans using real-w
Banker har en essentiell roll i det moderna samhällssystemet funktion som betalningsförmedlare, kreditgivare och mottagare av ekonomiska medel från allmänheten som placeras till exempel på konto i bank. Utan ett fungerande banksystem blir möjligheten för företag och privatpersoner att förmedla betalningar till varandra, söka krediter eller förvara sina intjänade medel på ett tryggt sätt starkt bFinancial companies in general, and banks in particular, plays an essential role for the function of modern society. Without a working banking-system there would be no effective way to make payments and hardship would meet the credit-market. Some banks have been thought of as ”to big to fail”, although during the last years well-known international banks such as Leeman Brothers has been forced t
Thesis purpose: The purpose of this thesis is to (1) investigate if product attributes relevant for early stages of the product life cycle enable the survival of disruption and (2) to further examine if there are any specific product attributes related to later stages of the product life cycle enabling market innovation. Methodology: For the purpose of this thesis, qualitative semi-structured int
En spallationskälla börjar generellt med en kraftig linjär protonaccelerator, som skickar en högenergisk protonstråle rakt in i ett neutrontätt mål. Strålens högenergiska protoner frigör neutroner från de neutronrika atomerna i målet via intra-nukleära interaktioner, vilket är själva spalleringsprocessen. Desto högre effekt den levererade protonstrålen har, desto fler neutroner frigörs. Därmed reThe European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. a rotating Tungsten disk, it will deliver high-flux neutron beams to multiple beamlines at which scientific experiments will be conducted in many scientific disciplines. To simulate the proton beam and for cr
Tilläggsköpeskillingar har kommit att användas allt mer frekvent i förvärvssammanhang. Detta gäller framför allt i fråga om företagsförvärv men finansieringsmodellen används även i andra sammanhang såsom vid förvärv av fastigheter, patent, tjänster och så vidare. En tilläggsköpeskilling går ut på att säljaren får en fast del av ersättningen vid förvärvet medan möjlighet finns till en eller flera yEarn-outs have become more frequently used in acquisitions. This is particularly true in the case of acquisitions of companies. But the funding model is widely used even in other contexts such as the acquisition of property, patents, services and so on. An earn-out is a contract where the seller receives a fixed remuneration of the acquisition at the time of the contract while the possibility exis
Spatial analysis is dependent on the geo-referencing quality of the spatial data, as well as on the definition of the geographic context variables used. However, these facts are rarely taken into consideration in historical demographic research where the geographic factor is considered. An important obstacle in this kind of research is the availability of historical data (spatial and non-spatial),
The aim of the current study was to gain an overview of factors that can effect social secretaries motivation, both positively and negatively, in their work with social assistance. This study has focused on what the employee does rather than what he or she earns as a factor that leads to increased work motivation. To have motivated employees are important in every organization and above all in Hum
A user-friendly high-resolution intermediate complexity dynamic and spatially distributed flow model is crucial in urban flood modeling. Planners and consultants need to improve the accuracy of floods and estimation of risks. A new flow model will serve as a rapid tool to improve identification of these.

Summary: Upstream open reading frames (uORFs, often encoding so-called leader peptides) can regulate translation and transcription of downstream main ORFs (mORFs) in prokaryotes and eukaryotes. However, annotation of novel functional uORFs is challenging due to their short size of usually <100 codons. While transcription- and translation-level next-generation sequencing methods can be used for gen
Ground-level fine particulate matter (PM2.5) and ozone (O3) are air pollutants that can pose severe health risks. Surface PM2.5 and O3 concentrations can be monitored from satellites, but most retrieval methods retrieve PM2.5 or O3 separately and disregard the shared information between the two air pollutants, for example due to common emission sources. Using surface observations across China span
The production cross-sections for W± and Z bosons are measured using ATLAS data corresponding to an integrated luminosity of 4.0 pb- 1 collected at a centre-of-mass energy s=2.76 TeV. The decay channels W→ ℓν and Z→ ℓℓ are used, where ℓ can be an electron or a muon. The cross-sections are presented for a fiducial region defined by the detector acceptance and are also extrapolated to the full phase
BACKGROUND: Spatial epidemiological analyses primarily depend on spatially-indexed medical records. Some countries have devised ways of capturing patient-specific spatial details using ZIP codes, postcodes or personal numbers, which are geocoded. However, for most resource-constrained African countries, the absence of a means to capture patient resident location as well as inexistence of spatial d

The Van (forest) Gujjars, surviving as forest pastoralists in the central part of the Indian Himalaya, are a people who, due to their nomadic lifestyle, have since colonial rule found themselves at the margin of Indian society. This paper will look at the relationship between the Van Gujjars and their forest base in a historical perspective from colonial rule to 'conservation of nature' and the 'r
Flaxseed has recently gained attention as a functional food, and the effect of adding flaxseed (10%, 15%, and 20%) to tortillas was evaluated. The physicochemical characteristics and the free fatty-acid (FFA) content of the oil extracted from flaxseed-added corn tortilla were determined. The results showed that the lipid (4.27%) and protein content (9.10%) of the control sample was statistically l
In order to calculate building energy usage, apart from the technical characteristics, user related factors needs to be determined. Unless the user related factors are determined by specific project, the idea is to apply a standardized list of input data for a normal operation during a normal year, so the calculated energy value does not depend on variation of these factors. Such list was issued b
