This master thesis report describes a product development process with the aim to create a construction which ensures an easier installation by replacing screws with other alternative assembly methods. The project has been performed at Axis Communications AB, which is the market leading company in network cameras. A previous project called Rocky provided the idea of an excenter lock compressing an
Today, the world contains an unimaginably massive amount of digital information, increasing ever so rapidly and bringing about a wide range of opportunities across industries such as predicting future trends, combating crime to name a few. As a result, more and more organi-sations are investing heavily in Business Intelligence (BI) with the hope of gaining insights through data and analytics and h
This Master Thesis proposes to use a Spatial Hawkes Process to model the news flow in the world. The spatial part is divided in both geographical areas as well as different topics. Therefore, in the Hawkes model every news article corresponds to a point in space and time. In a certain region and topic the intensity of the released articles will be modelled with the Hawkes Process. This can be of i
The master thesis was carried out for Sandvik SRP in cooperation with the division of Production and Materials Engineering at the Faculty of Engineering at Lund University. This thesis is part of a larger research project with the title ”Blyfria kopparlegeringar” funded by Vinnova within SIO Produktion 2030. Lead-free bearing-materials, which could be used to replace the current bear-ing-material
In this work mathematical models of a granulating process plant have been determined. The plant is situated at the SUPRA company, Landskrona Sweden. The product studied is a fertilizer NPK. In the process there are oscillations in the material flow. The models will be used an attempt to explain and hopefully control the process better.
In the first stage it was tried to obtain a physical
To limit global warming to 1.5°C, concerted efforts to drastically reduce GHG emissions by 2030 are needed. Lund municipality has ambitious climate goals for 2030, however, high emissions from transport and especially private car use endanger their achievement. Building on transition management, this thesis aimed at supporting Lund’s climate goals by developing a knowledge base for the implementat
A series of photosensitizers for NiO-based dye-sensitized solar cells is presented. Three model compounds containing a triphenylamine donor appended to a boron dipyrromethene (bodipy) chromophore have been successfully prepared and characterised using emission spectroscopy, electrochemistry and spectroelectrochemistry, to ultimately direct the design of dyes with more complex structures. Carboxyli
A new simulation method for nonuniform polymer solutions between planar surfaces at full chemical equilibrium is described. The technique uses a grid of points in a two-dimensional thermodynamic space, labeled by surface area and surface separations. Free energy differences between these points are determined via Bennett's optimized rates method in the canonical ensemble. Subsequently, loci of con
In this thesis model reduction methods for linear time invariant systems are investigated. The reduced models are computed using semidefinite programming. Two ways of imposing the stability constraint are considered. However, both approaches add a positivity constraint to the program. The input to the algorithms is a number of frequency response samples of the original model. This makes the comput
High uncertainties are common in detailed quantification of the N budget of agricultural cropping systems. The process-based CoupModel, integrated with the parameter calibration method known as Generalized likelihood uncertainty estimation (GLUE), was used here to define parameter values and estimate an N budget based on experimental data from an organic farming experiment in south-west Sweden. Da
Parents influence the development of their offspring in many ways beyond the transmission of DNA. This includes transfer of epigenetic states, nutrients, antibodies and hormones, and behavioural interactions after birth. While the evolutionary consequences of such non-genetic inheritance are increasingly well understood, less is known about how inheritance mechanisms evolve. Here, we present a sim
Terrestrial Laser Scanning (TLS) is a technique to rapidly collect detailed and accurate data of an object. The technology can briefly be described as a laser beam emitted by an instrument which sweeps across a target object collecting millions of closely placed coordinates (x,y,z) in a matter of minutes. Terrestrial Laser Scanning technology has existed for a long time however only in recent year
Rätten till arbete, som utgör en av de mest centrala mänskliga rättigheterna och även ses som en grundläggande förutsättning för samhällsintegrering, är införlivad i en rad olika MR-instrument. Lika tillgång till arbetsmarknaden är en mycket viktig aspekt av denna rättighet, som även utmanar den underliggande norm om universalitet som präglar det internationella ramverket för mänskliga rättigheterThe right to work, as one of the most crosscutting and enabling socio-economic rights, as well as a basic requirement for social integration, is enshrined in a wide range of international human rights instruments. Equal access to the labour market is one important aspect of this right that challenges the underlying universality norm of the human rights regime by imposing on states the obligation t
This report is an evaluation of evacuation safety, during fire, in Söderhallarna, Stockholm. Söderhallarna is a combined market hall with regular stores, restaurants and offices. A lot of people visit Söderhallarna daily, especially during the greater holidays, such as Christmas and Easter. Many non-Swedish speaking tourists visit the market hall, emphasizing the importance to have easy to underst
The aim of this thesis is to present experiences and lessons learned from the initial implementation process of the rating system STARS at Washington University in St. Louis: mainly the strengths/opportunities can be used to overcome the weaknesses/threats that the STARS implementation may entail. Strengths and opportunities such as increased student involvement in processes such as assessing sust
Efterfrågan på sockerrör har de senaste åren ökat i takt med att fler länder strävar efter att minska sitt beroende av fossila bränslen. Som en följd har antalet sockerrörsodlingar kraftigt ökat i Brasilien vilket medfört en oro inför vilka effekter denna omvandling av ursprunglig mark till sockerrörsodling har på lokala hydrologin och klimatet. I det här arbetet har påverkan av sockerrörs expanThe demand for sugarcane has increased in recent years as more countries desire to reduce its dependence of fossil fuels. Therefore, the number of sugarcane plantations has rapidly increased in Brazil which raises concerns for what effect these conversion of original land to sugarcane plantations have on local hydrology and climate. In this thesis, the effects of sugarcane expansion on surface ru
Background: Concerns about the cardiovascular safety of medications used for the treatment of attention-deficit hyperactivity disorder (ADHD) remain. We aimed to compare the effects of pharmacological treatments for ADHD on haemodynamic values and electrocardiogram (ECG) parameters in children, adolescents, and adults. Methods: For this systematic review and network meta-analysis, we searched 12 e
Easy, low‐threshold access is widely regarded as a major advantage of online services. In Sweden, several municipalities are striving to increase the accessibility of their social services by responding to anonymous users online. This article considers the nature of the accessibility of these online services. Two online platforms were studied: (quasi‐)synchronous online chats and asynchronous onli
This essay is dealing with the question of the possibility for a non archaeologist to learn something about the Scandinavian Bronze Age by reading novels taking place in the specific period. I have studied novels written by Scandinavian writers between 1980 and present. Before I started I constructed nine different categories that I was to look for in the novels. The categories were constructed in
