This report describes the research, conclusions, and result of my Master Degree thesis project in Industrial Design at Lund University. The thesis was completed during the spring semester of 2018. The work was carried out in collaboration with Trimble Geospatial in Danderyd, Sweden. The main purpose of this thesis was to explore the future methods of working with geospatial instruments - s
PFAS is a group of long-lasting chemicals with multiple known toxicological effects which has been found everywhere in nature. One of the possible source points of PFAS is via landfill through leachate leaving the area. It is therefore important to investigate and implementing remediation techniques to reduce the contamination risk. This thesis focuses on two components, first a literature study w
Microfluidic devices have so far not seen widespread use, even though they could potentially be cheaper, better and faster than traditional methods. A possible reason for this is the lack of a middle step between one-of-a-kind experimental devices and cheap mass produced devices. With ongoing improvements in resolution it is starting to look possible that 3D-printing will fill this role. This the
Purpose: To explore why brands lose control over their identity due to internal actions or lack of actions when needed. The paper examines the key elements brands should focus on internally to prevent brand identity erosion which can negatively impact brand performance. Methodology: This paper explains the relevance of brand identity by a literature review and further builds on fundamental causes
In this master thesis we consider some phenomenological aspects of two-Higgs-doublet models, both elementary and composite ones. The emphasis is on calculating and understanding first order phase transitions in such models, constrained to be in agreement with existing collider data on the Higgs sector. We also consider the contribution to the gravitational wave background of the universe that woul
Open data is broadly expected to generate innovation and economic value for both the public and private sector. Though the diffusion of open data has kept a fast pace, knowledge of visualisation and points of access of open data remains low. Moreover, literature of the private-sector application of open data is still scarce. The first objective of this thesis is to increase the knowledge about the
LDMX is a fixed target experiment designed to search for light dark matter. The experiment will search for dark matter signatures using missing momentum and energy in events with electrons scattering in the target. Part of the experimental setup in this search is a high granularity electromagnetic calorimeter to accurately measure the energies of recoil electrons. In this thesis artificial neura
Det finns ett växande behov av miljövänliga sätt att transportera sig och därför har elcykeln slagit stort i Sverige. Elcykeln används ofta som transportmedel till och från jobbet men har potential att användas i andra sammanhang också. Miljöpåverkan orsakad av transport under semesterresor har uppmärksammats på senare tid. Samtidigt ökar efterfrågan på soft adventures, bekväma och tillrättalagda There is a growing demand for environmentally friendly ways of transportation, and therefore the electric bicycle has been booming in Sweden. The electric bicycle is often used as means of transportation to and from work, but has potential to be used in other situations as well. The environmental impact caused by transportation during holidays has recently gained attention. At the same time the de
Due to its high vulnerability, permafrost is one of the key features studied in the field of climate change impacts. Permafrost is widespread in the Arctic region. The majority of the area underlain by permafrost is however difficult to access for in-situ monitoring and it is difficult to get an overview of the current state of permafrost in many areas. Permafrost modeling provides a solution whi
A thermochromic ink is defined as an ink that exhibits colour changes depending on temperature. Thermochromic inks used in printing generally consist of an encapsulated three part system which includes a dye that changes colour, a compound that acts as a colour developer and a solvent. Due to the properties of the dye, the inks are always colourless above a certain temperature and coloured below a
Wildfires pose a serious threat to communities in different parts of the world, mostly in regions with a warmer climate. Due to the increased urbanization next to the forest and climate change, they are currently an issue to be addressed also in other parts of the world. The purpose of this thesis is to provide a first step in the direction of creating a holistic Vulnerability Assessment Method (V
BvHb1.2 is a sugar beet haemoglobin (Hb) and a good candidate to be used as an artificial oxygen carrier (AOC). 19 mutants of BvHb1.2 were produced with random mutagenesis and expressed in BL-21 E. coli. The Hb content in whole cells was determined by using a refraction index modifier by mixing cell suspensions with 35% BSA. The two mutants (4 and 15) with the highest Hb production were purified u
Changes in the agricultural landscape have caused declines in bumblebee species richness and abundance. Semi-natural grasslands are key habitats for bumblebees in agricultural landscapes, and therefore it is important to understand which habitat characteristics promote species-rich bumblebee assemblages in these habitats. In this study, I investigate the importance of trees within semi-natural gra
We discuss and compare four fixed parameter algorithms for finding the minimum weight triangulation of a simple polygon with (n - k) vertices on the perimeter and k vertices in the interior (hole vertices), that is, for a total of n vertices. All four algorithms rely on the same abstract divide-and-conquer scheme, which is made efficient by a variant of dynamic programming. They are essentially ba
Medications are of considerable help if healthcare providers are able to administer them to patients safely and appropriately. The medication use process is complex and a team of professionals – doctors, nurses, and pharmacists – work together with the patient for optimal treatment effect. The process involves many sub-processes and in every step there is a possibility for an error. Cytotoxic drug
A common application of nanometer-sized gold particles is as seed particles for growth of semiconductor nanowires, which are believed to act as highly promising building blocks in future electronic devices. In a majority of the reports of successful nanowire growth, gold has been the seed particle material of choice. In this review article we identify the different types of gold particles used to
