This thesis has been performed at Saab Technologies in Gothenburg. Saab is a global defense- and security company that specializes in air-, land and marine defense. Saab in Gothenburg develops effective solutions for monitoring, warning, location and defense systems. The thesis work which has been initiated by Saab, involves development of methods and tools in order to dimension the network compon
For the next 40 years, a rate of 3% of the European building stock per year needs to be renovated in order to meet the carbon and economic goals set out in the European Economic Recovery Plan. This puts high demands on the accuracy level of energy simulations software for predicting the energy need for retrofitted buildings. However, in most cases the simulated energy need does not correspond with
The aim of this project was to explore battery enclosures, specifically for e-scooter batteries, and whether additive manufacturing can be used to enhance existing designs. Furthermore, FEM and topology optimization were explored as tools for optimizing these designs. A modified Double Diamond approach was used as a guideline for the project. The modified version enters a prolonged optimization p
The role of women in post-conflict countries in Africa has always been less prioritised when working for reconciliation. Our aim in this thesis is to compare how the gacacas in Rwanda and TRC´s in South Africa treated the suffering of, and justice for women and what healing processes were put in place to help them. Truth Commissions are a form of reconciliation theory which will be further analyse
Amelogenin is a protein which has been found to have many interesting properties. Its biological function is a key part in organizing the crystals of the enamel and it has been found to have a clinical use for periodontal regeneration. Its self-assembling properties also makes amelogenin a suitable material for the fabrication of biomaterials. The aim of this project is to investigate the possibil
This thesis explores the value of collaboration in the development of temporary use in urban voids. By examining the role of different actors and capabilities of municipalities, the thesis investigates the conditions needed in order to realize the temporary use. Two cases in various geographical contexts, a temporary use in Malmö and a vacant lot in Arlöv, are studied. In addition to studying thes
Abstract Authors: Erika Johansson och Maria Winberg Rasmusson Title: Konflikt som lärandeprocess? En studie om konflikter inom HVB-hem för ungdomar. Conflict as a learning process? A study about conflict in youth institutions. [Translated title] Supervisor: Lars B. Ohlsson Assessor: Elizabeth Martinell Barfoed Conflicts are by no means unusual in society today and we were interested in how confl
Our aim is to study if and how LGBTIQ has been made invisible in the public library context, and how this can be countered. In order to do this, we have studied the public library of Hallonbergen, located in Sundbyberg, Sweden. Hallonbergen is the first library in Sweden certificated by RFSL (The Swedish Federation for Lesbian, Gay, Bisexual and Transgender Rights). The certificate shows that they
Biomedical science is rapidly developing in terms of more transparency, openness and reproducibility of scientific publications. This is even more important for all studies that are based on results from basic semen examination. Recently two concordant documents have been published: the 6th edition of the WHO Laboratory Manual for the Examination and Processing of Human Semen, and the Internationa
People are moving from rural to urban areas at an unprecedented rate, resulting in a high concentration of people subsisting on outside resources being constantly brought in. This presents a variety of complex sustainability problems. It is a resource-intensive system susceptible to supply shocks which could threaten food security. Many foods grow in cities, such as fruits on city trees, so utilis
This thesis has two major purposes: (1) to create a 3D virtual “reconstructive” model of the peristyle with the nymphaeum wall (room b) of the house V 1,7 (House of the Bronze Bull) in Pompeii, and (2) to prepare a probability map based on this model that will show the reliability level for each individual part. The author underlines the importance of recording paradata of the entire workflow. The
This paper proposes that the maximum entropy principle can be used for determining the drop size distribution of hydrometeors. The maximum entropy principle can be applied to any physical systems with many degrees of freedom in order to determine a distribution of a variable when the following are known: 1) the restriction variable that leads to a homogeneous distribution without constraint and 2)
Emissions of greenhouse gases in all sectors of society must reach near zero, in developed countries preferably by 2050, in order to reach climate policy objectives. Alternatives and strategies for the energy and transport sectors are relatively well understood but the basic industries are often overlooked, not least in sustainability transition and innovation system studies. The policy and techn
The damage caused by the worldwide increase in natural disasters is staggering, with the poor and marginalised slum communities being the most vulnerable. This paper analyses the key variables and their causal relations underlying the complex system of risk and disaster occurrence in slum areas in El Salvador. Slum dwellers’ views and knowledge are the focus of this inquiry. A better understanding
Background: Lentiviral vectors hold great promise as gene transfer vectors in gene therapeutic settings. However, problems related to the risk of insertional mutagenesis, transgene silencing and positional effects have stalled the use of such vectors in the clinic. Chromatin insulators are boundary elements that can prevent enhancer-promoter interactions, if placed between these elements, and prot
Results on fabrication and DC-characterisation of vertical InAs nanowire wrap-gate field-effect transistor arrays with a gate length of 50 nm are presented. Each nanowire array was processed into a transistor with a systematic variation in a number of wires and wire diameter over the sample. Extensive studies have been performed on the influence of wire number and diameter on the transistor charac
