We test a new approach to calculate the mean velocity and velocity dispersion for a sample of nearby stars when their radial velocities are not available. The most commonly used method (here called the projection method, PM) was introduced in a paper by Dehnen & Binney (1998). That method is here compared, theoretically and numerically, with an application of the Maximum Likelihood (ML) method
The thesis explores online knowledge production around a subject that has been considered taboo and inappropriate through history – sexual, reproductive and genital health for people with female genitals. Therefore, it also examines the political potential of coming together to openly discuss such “delicate issues”. The focus of the study is the Swedish Facebook-group “Fittlife – underliv och häls
Power systems operate at a specific frequency and constantly require a balance between production and consumption of electricity in order to maintain the frequency within a certain interval. Larger frequency deviations can cause blackouts or damage equipment connected to the grid. Balancing functions that stabilise the grid are referred to as \textit{ancillary services}, which in Sweden include th
Som en följd av EU-beslutet om ett nettonollutsläppsmål till 2050 har flera industrier utvecklat färdplaner för hur dessa utsläppsminskningar ska uppnås. Det här examensarbetet undersöker kemiindustrins färdplaner i syfte att bedöma hur de ser på sin roll i att nå EU:s utsläppsmål. Teknikerna och strategierna som används i färdplanerna för att nå utsläppsminskningar varierar stort. Ofta antas att Following the decision set by the EU of a net-zero greenhouse gas emission target for 2050, several industries have made roadmaps for how these reductions will be achieved. This thesis investigates the chemical industry roadmaps in order to assess how they envision their role in reaching the EU target. The technologies and strategies used in the roadmaps to reach the reduction targets vary widely,
The aim of this project is to establish a workflow that transforms CT-scanned images of paperboard into a calibrated Representative Volume Element (RVE). A RVE is defined as the smallest volume that accurately captures the macroscopic behaviour of the material. First, CT-scanned images are converted into a finite element model that rep- resents the microstructure of the paperboard. Secondly, a di
Bioacoustic sound event detection (SED) is a critical field for biodiversity monitoring, yet the high cost of annotating data poses significant challenges. This thesis explores the application of active learning strategies to reduce the amount of annotated data required for effective model training. This is done for a segment based SED model, where batch active learning is performed by querying fu
The need for speed in communications systems is increasingly prevalent in modern society, which is one of the driving factors for the evolution of new technologies. At the forefront of this evolution are Multiple-input Multiple-output (MIMO) systems. Through the usage of many antennas at the base station (BS) and user equipment (UE), significantly enhances the potential maximum data transfer rates
Flooding in oil palm plantations in Southeast Asia is a common problem. The oil palm’s habitable range is restricted to lowland equatorial areas, and the high rainfall and degraded landscapes associated with oil palm cultivation leaves oil palm prone to flooding. Flooding diminishes yields in mature palms, increases mortality in young palms, and disrupts operational processes. This reduces the ec
In October 2022, the European Commission announced a legislative proposal to make instant payments in euro available to all citizens with a bank account in the EU and EEA countries. When adopting new payment technologies, it can be challenging to balance security and convenience. Consideration must be given to whether compromised security is an unavoidable effect of instant payments or if both obj
This study investigates interculturality in health communication and deriving power relations. The Bilharzia Storytelling Lab 2022 in Kigali is a health communication program devoting significant attention to the role of culture and representing a new approach to respectful health communication practices. Exploring the Storytelling Lab methodology and its roles provides insights into the innovativ
Credit activity is essential for financial institutions, acting as the primary means banks deploy resources and generate revenue. As a key indicator of financial distress, corporate default has severe repercussions on investors, creditors, regulators, and policymakers. Credit risk embodies the uncertainty banks confront prior to lending, accounting for the partial or complete non-recovery of loan
The establishment of Indonesian AID can be seen as Indonesia’s official statement to the world on its intent of playing a more prominent role as a donor of international development aid. However, looking at the available data, it seems that Indonesian AID is still deep in the early days of its establishment. Little seems to have gone into “enforcing” its role as donor, with “reorganizing” seeming
To validate and evaluate the psychometric properties of the ALPS-Neo, a new pain assessment scale created for the continuous evaluation of pain and stress in preterm and sick term infants.
Ten countries have established quotas for female representation on publicly traded corporate and/or state-owned enterprise boards of directors, ranging from 33 to 50 %, with various sanctions. Fifteen other countries have introduced non-binding gender quotas in their corporate governance codes enforcing a "comply or explain" principle. Countless other countries' leaders and policy groups are in th
BACKGROUND: Multiple laboratory tests are used in the diagnosis and management of patients with diabetes mellitus. The quality of the scientific evidence supporting the use of these assays varies substantially. APPROACH: An expert committee compiled evidence-based recommendations for the use of laboratory analysis in patients with diabetes. A new system was developed to grade the overall quality o
Objective: To determine the association between radiographic osteoarthritis (OA) and pre-operative function in patients undergoing primary knee replacement. Methods: Single centre study examining pre-operative outcomes in a consecutive series of 525 patients who underwent primary knee replacement for OA between January 2006 and December 2007. Pre-operative data included: demographics, American Soc
An updated search is performed for gluino, top squark, or bottom squark R-hadrons that have come to rest within the ATLAS calorimeter, and decay at some later time to hadronic jets and a neutralino, using 5.0 and 22.9 fb(-1) of pp collisions at 7 and 8 TeV, respectively. Candidate decay events are triggered in selected empty bunch crossings of the LHC in order to remove pp collision backgrounds. S
The purpose of this study is to present a new and improved method for translating the electrocardiographic changes of acute myocardial ischemia into a display which reflects the location and extent of the ischemic area and the associated culprit coronary artery. This method could be automated to present a graphic image of the ischemic area in a manner understandable by all levels of caregivers; fr
