Climate change is one of the biggest challenges facing today's society. The construction sector contributes with a substantial part of the country's carbon dioxide emissions and accounts for a large part of Sweden's public procurement. Setting environmental requirements is therefore a very important part of the procurement process to ensure that the production of buildings and infrastr
In this thesis the automation of an optical sight validation process was studied. The goal was to find a solution for controlling the position of a red dot in a red dot sight. A red dot sight is a non-magnifying reflector sight in which the user sees a red dot instead of a reticle. The movement of the dot was performed by fastening and unfastening adjustment screws on the sight. A side goal was to
Capacity development in the field of disaster risk reduction is suggested by the Sendai Framework to be the primary tool for obtaining the goals of globally reduced disaster risk. However, ownership in capacity development initiative is often skewed towards the external organization. This thesis aims to understand the perceived success factors and challenges for the personnel in a governmental org
A hydraulic system is designed to transport fluid power over large distances, from pumps to actuators where the fluid power is transformed to mechanical power. The submarines, built and designed by Saab Kockums, utilises such systems. There are, however, challenges as the hydraulic pumps consume much energy, and the system accumulators command significant space. As both energy and space are limite
The aim of this paper was to study the relatedness of stress and emotional labor in the daily work of the school social worker in the 10th-13th year of school (svenska gymnasium) in Sweden. The aim also included exploring experiences of the impact of the relationships with coworkers within the context of experienced work related stress. The chosen method for this study was a qualitative approach w
Since the gang rape of a physiotherapist student in Delhi 2012 the media reporting on sexual violence has increased by 30 percent. Several studies have looked at how media report on sexual violence in India, but very few have looked at the increased news reporting from a critical point of view. This thesis draws upon interview narratives collected in Delhi in February and March 2016 and looks at h
Summary Title: Sustainability reporting in Sweden - Possible effects from EU-directive 2014/95/EU Amount of words: 25 807 Authors: Albin Askman Junhede, Tobias Carlsson och Viktor Johansson Advisor: Per Magnus Andersson Key words: Sustainable development, sustainability report, guidelines for sustainability reporting, comparability, EU-directive 2014/95/EU. Purpose: With the basis in an ana
We present a study of a novel variant of the Self-Organizing Map (SOM) called the Associative Self-Organizing Map (A-SOM). The A-SOM is similar to the SOM and thus develops a representation of its input space, but in addition it also learns to associate its activity with the activity of one or several external SOMs. The A-SOM has relevance in e.g. the modelling of expectations in one modality due
Adaptive spectral estimation techniques are known to provide good spectral resolution and contrast even when the observation window (OW) is very short. In this paper two adaptive techniques are tested and compared to the averaged periodogram (Welch) for blood velocity estimation. The blood power spectral capon (BPC) method is based on a standard minimum variance technique adapted to account for bo
10 June 2026 12:00 to 17:00 | Seminar The adoption of Artificial Intelligence (AI) and Machine Learning (ML) presents several challenges, among which the lack of trust in the decisions made by such systems remains a major concern. Formal methods have historically provided the foundation for rigorously verifying software systems, and they could play a key role in fostering trust in AI/ML technologi

The Permanent Establishment (PE) concept plays a key role in the distribution of taxing rights between States by determining when the profits derived by an entity are taxable in a State other than the State of its residency. This concept, originally, evidenced the existence of sufficient economic allegiances between a non-resident entity and a State to justify taxation therein. However, the evolut
Survival after childhood cancer has improved dramatically during the past four decades, resulting in a five-year survival rate of 80% in children recently treated for cancer in the Nordic countries. However, these advances in treatment and survival has come at a price, and many survivors face significant treatment-induced sequelae, most of which only become clinically apparent many years after the
A laboratory creasing device to capture the most important properties of a commercial rotary creasing tool was designed. Finite element analysis of the creasing of a multiply paperboard in the laboratory crease device was presented. The multiply paperboard was modeled as a multilayered structure with cohesive softening interface model connecting the paperboard plies. The paperboard plies were mode
Northern high-latitude wetlands are well known to seasonally emit methane gas into the atmosphere, and therefore contribute to greenhouse effects. While these gas emissions are well documented, their causes are not well understood. The method described in this work can be used to analyze the changes happening in the soil during gas emissions, and therefore help the understanding of the sub-surfac
Background: S100A9 has been shown to be important for the function of so called Myeloid Derived Suppressor Cells (MDSC). Cells with a similar phenotype are also involved in pro-inflammatory processes, and we therefore wanted to investigate the gene expression and function of these cells in animals that were either subjected to chronic inflammation, or inoculated with tumors. Methods: CD11b(+)Ly6C(
This paper presents the results of an explorative study on the strategies and tactics applied by the mechanical designer during the later phases of the design process. The method chosen for this study is experiment-based, which is appropriate for an in-depth examination of the designer's activities. Six experiments have been run based on three dimensions: 1) the carrying out of basic design tasks
