The first aim of this project is to make high-order harmonic (HHG) setups more compact and user-friendly, by including a micro-channel plate (MCP). Simulations of the transmission properties of an MCP has been performed. These simulations displayed introduced structure in the far field, but a very well behaved beam in the near field. Further, the wavefront of the zeroth order diffraction spot of M
Examensarbetet är utfört på och i samarbete med Imtech Ventilation i Malmö. Författarens avsikt har från början varit att skapa något som kan vara till stor nytta för företaget. Därför har examensarbetet utförts i nära samarbete med Imtech Ventilations medarbetare. Författaren har gjort en bakgrundsanalys av energikravs-läget i byggbranchen. Detta för att ta fram en validerad problemformulering ocThis master thesis is performed on and in cooperation with Imtech ventilation in Malmö. The author's intention was from the beginning to create something that can be of great benefit to the company. The master thesis has been carried out in close cooperation with the employees of Imtech Ventilation. The author has done a background analysis of the current excising energy regulations. This was
Studien i fråga hade som huvudsyfte att undersöka moralisk stress hos rekryterare på rekryterings- och bemanningsföretag i privat verksamhet i Sverige. Vidare syfte var att undersöka dilemman av fyra andra psykologiska faktorer kopplat till arbetet som är relevanta för moralisk stress: kognition, emotion, kontroll, samt stressreaktioner. För moralisk stress och samtliga faktorer undersöktes skillnThe study aimed at examining recruiter’s experience of moral stress at recruiting and staffing companies in Sweden. Further purpose was to investigate dilemmas of four other psychological factors related to work, relevant for moral stress: cognition, emotion, control, and stress reactions. For moral stress and all other factors, differences based on sexes and work experience were investigated. An
Parallel-elastic joints can improve the efficiency and strength of robots by assisting the actuators with additional torques. For these benefits to be realized, a spring needs to be carefully designed. However, designing robots is an iterative and tedious process, often relying on intuition and heuristics. We introduce a design optimization framework that allows us to co-optimize a parallel elasti
Sedan 2002 har det funnits misstankar om att Irans kärnenergiprogram inte endast har ett civilt syfte utan att programmet även har militära syften. USA är det land som har satt in starkast sanktioner mot Iran då USA menar på att Iran utvecklar kärnvapen och ett Iran med kärnvapenkapacitet är ett säkerhetshot till USA och dess allierade i regionen. Frågan som ställs är på vilka sätt Irans kärnenerg
Objective: To redesign the current assembly process of the Ektorp Sofa from IKEA in order to improve cycle times, quality levels and to reduce, if possible, costs associated with manufacturing, production times and materials. IKEA wants to increase either the productivity or the quality standard of the Ektorp Sofa by simplifying the processes involved in the construc-tion of the sofa and modernizi
Background: Childhood cancer survivors (CCSs) have an increased risk of developing chronic health conditions. Evidence suggests that poor health behaviors further increase health risks. Healthcare professionals (HCPs) involved in survivorship care have a key role in providing health behavior support (HBS) but can feel limited in their ability to do so. This study aims to explore European HCPs perc
For many years, universities represented the ultimate outpost for professional autonomy in Western democracies. Despite little insight into the professional practices of scholars or administrators, governments provided the academic profession with extensive discretion, including the freedom to regulate qualifications for positions, terms for promotion, quality standards, goals, performance indicat
If individuals occupy habitats in a way that maximizes their fitness, if they are free to occupy the habitats they choose and if fitness declines with population density, then their abundance across habitats should follow an ideal free distribution. But, if individuals are genetically related, this simple fitness-maximization mechanism breaks down. Habitat occupation should obey Hamiltons rule (na
Introduction: A laparotomy is commonly required to gain abdominal access. A safe standardized access and closure technique is warranted to minimize abdominal wall complications like wound infections, burst abdomen and incisional hernias. Stitches are recommended to be small and placed tightly, obtaining a suture length-to-incision length (SL/WL) ratio of ≥ 4:1. This can be time-consuming and diffi
Constructive Alignment (CA) is neither the panacea, nor the unalloyed evil depicted in the majority of higher education discourses. But rather, the theory is a heuristic and accessible representation of commonly agreed upon aspects of modern curriculum and educational theory, designed explicitly to support learning and teaching. However, when imposed top-down for accountability purposes, or used a
Spatially coupled turbo-like codes (SC-TCs) have been shown to have excellent decoding thresholds due to the threshold saturation effect. Furthermore, even for moderate block lengths, the simulation results demonstrate a very good bit error rate performance in the waterfall region. In this paper, we discuss the effect of spatial coupling on the performance of TCs in the finite block-length regime.
III-V nanowires are candidate building blocks for next generation electronic and optoelectronic platforms. Low bandgap semiconductors such as InAs and InSb are interesting because of their high electron mobility. Fine control of the structure, morphology, and composition are key to the control of their physical properties. In this work, we present how to grow catalyst-free InAs1-xSbx nanowires, wh
We might describe the philosophical issue of human freedom and moral responsibility as an existential metaphysical problem. Problems of this kind are not just a matter of theoretical interest and curiosity: They address issues that we care about and that affect us. They are, more specifically, relevant to the significance and value that we attach to our lives and the way that we lead them. Accordi

Background: Computed tomography (CT) of the brain is performed with high local doses due to high demands on low contrast resolution. Advanced algorithms for noise reduction might be able to preserve critical image information when reducing radiation dose.PurposeTo evaluate the effect of advanced noise filtering on image quality in brain CT acquired with reduced radiation dose.
