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

This thesis analyses the relationship between the presence of economic agglomerations and regional economic growth in Mexico during the period 2005- 2018. The focus is mainly toward understanding the influence of clusters in the service sector due to its increasing potential for driving the economy. The study also examines the effect of agglomerations on regional income inequality. To estimate the

Denna avhandling beskriver studier av hur metallkomplex som fungerar som katalysatorer i lösning kan absorberas i s k metall-organiska nätverksstrukturer (metal-organic frameworks = MOFs). MOFs är porösa kristallina material som har en bred funktion i såväl laboratorium som industri. Genom sådan absorption kan det lösliga komplexet inkorporeras i håligheter i nätverket; det lösliga komplexet befinThis work constitutes the results from a one year master thesis research project (Sep, 2019 to Aug, 2020). Metal-Organic Frameworks (MOFs) have been used for encapsulation of homogeneous catalysts to generate heterogeneous catalysts. This work describes the incorporation of the non-heme iron complex [(Fe(II)N4Py)]2+ and two molybdenum−sulfur clusters (MOS) into the pores of UiO-type MOFs via absor

The European Spallation Source (ESS) will be the world's most powerful next-generation neutron source. It will deliver a high-energy proton beam to the target with a high degree of control. With many components operating at their engineering limits, instrumentation must detect errant beam conditions and suppress proton beam production. One of the beam diagnostic instruments installed will be A

Olösliga problem blir lösbara med framtidens kvantdatorer! Under 1900-talet gjordes oerhörda framsteg i vår förståelse av kvantmekaniska fenomen, men för varje besvarad fråga väcks två nya. Många högaktuella frågor, och mål, gäller förverkligandet av kvantdatorn, där en av de främsta frågorna är: vilka kvantmekaniska fenomen ska utgöra grunden för kvantdatorns grundkomponent (en ’qubit’)? AlternatIn this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. The contact quality assessment is based on parameters extracted via electrical characterization performed mK temperatures in

Talent is seen as a critical factor in promotingregional technological and economic development. Researches on talent attraction and retention policies have been explored in the western context. However, little has been studied in the Chinese talent attraction and retention policy yet. In the meantime, many Chinese cities have implemented talent attraction policies to attract talented workers. The

A green transition requires to drive public and private capital towards investments in line with environmental norms. Scholars are constantly looking into the performances of sustainable finance and how to measure them. Yet, the perspective from financial firms on climate finance has hardly been studied. This research addresses this gap by offering a qualitative analysis of Swedish financial firms

Telomeres have an important role in cell replication and maintenance and are known to shorten at each cell division. They have been linked to lifespan and mortality in wild populations, and induced stress and environmental conditions are thought to accelerate telomere shortening which may lead to shorter lifespan. The ‘disposable soma’ theory of aging, predicts that investment in reproduction will

: I mars 2020 ställdes världen på ända då WHO utnämner covid-19 som en pandemi. Handeln, som sedan tidigare redan står inför stora utmaningar, tvingas ställa om. För den fysiska handeln medför detta behov av att förändra den fysiska miljön inom vilka kunder och medarbetare vistas, för att kunna säkerställa social distansering. Med utgångspunkt i detta syftar studien till att ge en mångfacetterad b

Power amplifiers are very important components in the area of wireless communications. However, they are non-linear devices and they seem to achieve high efficiency when they are operating in the non-linear regions, at the cost of being more power-consuming. In order to linearize their behavior, designers have been considering many methods. Among those, the digital pre-distortion tends to be the m

Prostate cancer is one of the most commonly diagnosed diseases among men, both in Sweden and the US. It is a consuming disease that tears on both the patient and his relatives. The different stages of disease are many, as are the different treatment options and drugs. New diagnostic techniques are constantly being developed and more imaging methods become available. As new digital techniques evolv
