The phase field method emerged as a tool to solve free boundary problems with a sharp interface. In previous methods, this involved the computationally inefficient and complicated tracking of a moving interface. The phase field method overcomes this limitation by introducing an auxiliary variable called the order parameter which varies continuously over the whole domain and takes on finite values
Despite the increased focus on sustainable urban development both within academia and in urban planning practices, authors seem to agree that we are mostly continuing business as usual and are not embarking on different socio-environmental trajectories. On the contrary, such urban sustainability practices can often lead to processes of displacement and gentrification, thus worsening the conditions
In this thesis, InGaAs fins with vertical sidewalls consisting of {110} facets were epitaxially grown on InP(111)B substrates using metalorganic vapor phase epitaxy. A lithography patterned hydrogen silsesquixane growth mask was used to promote the formation of vertical {110} facets during the growth. The relative growth rate of the {111B} and {110} facets was controlled by the input V/III ratio i
Two decades after emerging from war and after many years of delay, Bosnia and Herzegovina at last submitted an EU membership application in 2016. There is little doubt, however, that candidate status and accession are still a long way off. Reform process is slow, and the country’s state of democracy is undermined by a variety of factors. To evaluate perspectives for the future, this paper investig
The purpose of this master’s thesis project is to aid Thomson Reuters to forecast soil moisture, enhancing the agricultural productivity of its clients. This thesis focuses on testing the company’s HBV model (HBV-TR) to accurately produce daily soil moisture values in Brazil, France, and the U.S.A. The problem is that, up to this day, the most reliable monitoring of this soil water content is als
During the past few years the focus on bioprocess monitoring and control has increased. An area still under intensive development is the sampling methods for efficient and rapid analysis during fermentations. In this thesis, an online-sampling and monitoring scheme was developed using the versatile automated continuous flow system (VersAFlo) for recombinant protein production. From the implementat
With modern day interest to continue the reduction of harmful emissions and improve the efficiency of combustion devices, the need to further improve upon accuracy and ability to describe combustive processes is of high value. Nowadays, multiple capable point (0D) and two-dimensional measurement (2D) techniques exist for flame investigation, however as combustion nearly always is a three-dimension
The accuracy and portability of depth cameras have increased by a lot in recent years, which allows for advanced 3D scanning of the environment for robotic applications. In this thesis we have developed a system that uses a depth camera mounted on a robot arm to identify and localize arbitrary objects, and give hints on how to move the camera to get better localization results. The system works by
CellaVision develops automated microscopy for blood analysis. Their products can pre-classify 19 different types of white blood cells and support the medical technologist performing the final classification. CellaVision provides reference cells. The reference cells are a fixed set of cells handpicked by a technologist, chosen to be typical for that specific class. The reference cells are static, i
Antalet personer som lever med en kronisk sjukdom ökar, detta som en konsekvens av bland annat en snabbt ökande äldre befolkning. Kroniska sjukdomar orsakar inte bara mänskligt lidande, utan är också en ekonomisk börda för samhället. För att lindra lidandet och minska kostnaderna kopplade till kroniska sjukdomar kan användandet av digitala hälsotjänster vara en möjlighet. För närvarande är förväntThe amount of people living with chronic diseases is increasing. Chronic diseases do not only induce human suffering, it is also an economic burden on society. To ease the suffering and reduce the costs connected to chronic diseases, the usage of digital health services might be a possibility. Currently, the expectations on such services are high, but not met. To better meet the expectations, this
This paper examines how worries about war affect the political participation of women and men in Ukraine. The analysis is based on secondary data from the seventh wave of the World Values Survey 2017-2020. By constructing linear regressions, I examined whether there is a correlation between the worries about the war and the political activity of women and men in Ukraine. This allowed us to see how
The objective of this thesis has been to improve the camera controls of a fixed-wing drone to be used in maritime search-and-rescue operations by the Swedish Sea Rescue Society (SSRS). A gimbal control interface (GCI) has been implemented that displays the video feed of the drone camera while taking control inputs from a joystick that moves its view in real-time. In the thesis, the GCI has been
Den ökande andelen variabla förnybara energikällor i det svenska elsystemet har medfört ett växande behov av flexibilitet och balanstjänster. Batterienergilagringssystem betraktas som en nyckelteknik för att möta dessa behov, men deras ekonomiska lönsamhet är i hög grad beroende av marknadens utformning, geografisk placering samt vald operativ strategi. Syftet med detta examensarbete är att analysThe increasing share of variable renewable energy sources in the Swedish power system has led to growing demand for flexibility and balancing services. Battery energy storage systems (BESS) are widely regarded as a key technology to meet these needs, yet their economic viability depends strongly on market design, geographical location, and operational strategy. This thesis assesses the revenue pot
The thesis assesses the role of grassroots organisations in climate action through sustainable food practices, focusing on social innovation, collective learning, community-building and local resilience inside the city of Lund, in the Skåne region of southern Sweden. It intends to understand how local groups, combining practical knowledge with community-based innovations, collaborate to build a cu
Reliable six-degree-of-freedom pose estimation is a key requirement for autonomous on-orbit servicing (OOS), in which a robotic spacecraft performs tasks such as inspection, maintenance, and life extension of other satellites in orbit. However, generating trustworthy ground truth for algorithm development remains challenging. This thesis investigates calibration, sensor evaluation, and sensor fusi
The aim of this project is to discuss how designers can contribute to gender equality and female empowerment in craft-production industry. The study was done as a collaboration with the Indian organization Industree to study methods designers can use to assure that the economic/social balance in the value chain is fair. The organization works with craft-production as a means of generating income a
