Sound ranging is a method to locate sources of sound waves using microphones or other types of receivers at known reference positions. Nowadays, these receivers can be made both very small and powerful, lasting for a long time on a single battery charge, making them suitable for longtime outdoor purposes such as detecting artillery fire or other loud sounds. In this master thesis, we present a sou
Diversity is an important part of the health of our planet’s ecosystems and processes. Anthropogenic factors like urbanization and agriculture have altered the landscape and in turn had a negative effect on diversity. Efforts to maintain and preserve diversity for long term ecological strength, have led to more holistic approaches by handling many types of diversity under the same field of “landsc
Cellodling är ett viktigt verktyg för forskning om neurologiska sjukdomar, men traditionella metoder där celler odlas på glasytor har många brister och forskare söker därför efter nya typer av substrat. I detta examensarbete har vi undersökt hur nanofibrer kan användas som substrat för odling av hjärnstamceller. Vår studie visar att nanofibrer fungerar som substrat, men att mer forskning behövs föNovel biomimetic three-dimensional scaffolds have emerged over the last decades, and are promising for applications in regenerative therapies, as well as in in vitro disease modelling and drug testing. Thanks to their added dimension, these scaffolds are able to more accurately mimic the topography of native cellular microenvironments compared to traditionally used two-dimensional culture substrat
Uppsatsen klargör svenska arbetsgivares anpassningsskyldighet och hur långt den sträcker sig. Uppsatsen undersöker även om det finns en liknande skyldighet i Norge och Danmark och sedan görs en jämförelse mellan de olika länderna. Skyldigheten att anpassa arbetet i en situation där en individ har en funktionsnedsättning är lika i de skandinaviska länderna. Detta beror bland annat på att länderna h
This project started with an exploration of how logistics that is created by design could be re-imagined, leaving some material of an product to be sourced by the user locally. Saving weight and space during transportation, but also to generate another kind of user participation and knowledge With this in mind, a collaboration with IKEA was initiated with the end goal to do a product for their sh
Världen är i ständig miljö- och hälsofrämjande utveckling, där ny forskning och upptäckter hela tiden driver marknadskrav och bidrar till restriktioner. Plastindustrin har länge varit under luppen, till stor del för fossila råvaror och nedskräpning, men även då vissa plastmaterial innehåller ifrågasatta tillsatser. Flexibel Polyvinylklorid (PVC) är en typ av plast som används mycket i dagens samhFlexible Polyvinyl chloride (PVC) is a plastic material commonly used in today’s society and a fundamental material for a lot of sectors. It has advantages over other polymers such as energy-efficient production, flame retardancy, durability and cost-effective. The one important component in flexible PVC that gives it is flexible properties is the plasticizer. The most common plasticizers used are
As social desirability has not received enough focus when estimating the predictive power of personality in explaining well-being variance, recent accounts of the relationship between ratings of personality and well-being might be overestimated. The current study investigated the influence of social desirability, operationalized as the evaluative factor of personality (i.e., the tendency to react
Histopathology is the procedure used in medicine to optically examine microscope-images of tissue samples (biopsies) in order to study the manifestation of disease. It is used, for example, to diagnose the spread and type of cancer tumors, which have implications on the chosen treatment. Currently this type of analysis is done manually by trained professionals. It is time consuming and the diagnos
This thesis investigates the possibility of computing interval estimates for metrics that pertain to traffic safety based on surrogate measures of safety. A probabilistic model of the (near) crash count is defined using the generalized Pareto distribution and three different methods for calculating confidence intervals for the corresponding intensity parameter are proposed. We consider the delta m
This thesis seeks to understand the narrative presented by Mette Frederiksen in an interview published in Jyllands-Posten on October 16, 2019 bearing the header The EU-cooperation is disconnected from the world, we are a part of through interpretations from relevant experts. In order to extract what can be learned about the Danish future relation to the EU, the thesis examines how four Members of
In contemporary tourism, technology enables travelers to make travel arrangements in various ways, for example they can reserve tickets directly from airlines company’s website or purchase products from online travel agencies. Considering that travelers have many alternatives but insist in making transactions with traditional travel agencies, there must be something that makes traditional travel a
Artificiella Neuronnät är datorvärldens ekvivalens till det mänskliga nervsystemet. Precis som nervsystemet är ett nätverk av neuroner som är kopplade till andra neuroner med nerver så är det artificiella neuronnätet ett näverk av noder som är kopplade till andra noder med länkar. Det artificiella neuronnätet tar en inputsignal som skickas igenom nätverket och där noderna signalen stöter på på vägNeuroevolution is a field within machine learning that applies genetic algorithms to train artificial neural networks. Neuroevolution of Augmenting Topologies (NEAT) is a method that evolves both the topology of the network and trains the weights of the network at the same time, and has been found to successfully solve reinforcement learning problems efficiently and the XOR problem with a minimal
Receiving social support is central in dealing with life events in general. Intersex or disorders of sex development (DSD) people and especially adolescents, however, have been found to be reluctant to share information about their sex development and often find themselves dealing with it on their own. A shift toward more psychosocial care for intersex/DSD people and human rights claims for more a
Behovet av att estimera elförbrukningen timme för timme under årets alla dagar har funnits länge hos elnätsbolag och forskare, framför allt på nätstationsnivå. Många metoder som används i Sverige idag är dock gamla och använder endast kundernas årsförbrukning som indata under hela året trots att det blir allt vanligare med nätbolag som mäter energiförbrukningen varje timme hos samtliga kunder. MedThe power system today is facing a transformation from fossil and nuclear energy sources to renewable energy sources such as solar- and wind power. At the same time electric vehicles are becoming more common every year. To analyse how these two changes affect the power system it is crucial to understand how loaded the power system is today from traditional loads on a local and regional level. The
This paper investigates if there was an opportunistic politcal cycle in transfers and taxes in Sweden during the period 1982-2019. A regressional model with conditional effects is employed to condition the cycle on performance in an opinion poll and to account for partisan differences. Significant results are found in both transfers and taxes but for taxes, the results come into question due to li
The purpose of this study is to advance the theoretical knowledge on the influence and benefits of business incubator networks in direct connection to residing Early and rapid internationalizing firms. A qualitative research method was used in order to shed light on the workings of Swedish incubator networks and how residing Early and rapid internationalizing startups make use of them to overcome
The conditions under which children are brought up in cities have long been discussed, and in connection to that the Convention of the Rights of the Child became law in Sweden in January of 2020, there is reason to study how urban planning can play a role in its fulfilment. Child impact analysis is a process that can raise the child-perspective, the child’s own perspective and the right-of-the-chi
