Experiments have shown that the time is now ripe for a new generation of interactive learning tools for control. The tools are based on objects which admit direct graphical manipulation. During manipulations, objects are updated instantaneously, so that relations between objects are maintained all the time. The tools are natural complements to traditional education, and allow students to quickly g
A new generation of N-heterocyclic carbene palladium(II) complexes containing vinyl groups in different positions in the backbone of the N-heterocycle have been developed. The fully characterised monomers were copolymerised with divinylbenzene to fabricate robust polymer supported NHC-PdII complexes and these polymers were applied as heterogeneous catalysts in directed C-H halogenation of arenes w
Avrinningsområdet Mundaú har sitt ursprung i den Brasilianska delstaten Pernambuco och rinner i sydöstlig riktning mot Mundaúlagunen längs Atlantkusten tillhörande delstaten Alagoas. Området faller under nationell jurisdiktion, är relativt oreglerat och erfar både översvämningar och torrperioder. Modellering av avrinningsområdets hydrologi kan ge en fördjupad förståelse av dessa händelser och hur The relatively unregulated, union domain Mundaú river basin, upper reaches originating in the Brazilian state of Pernambuco and flowing southeast to the Mundaú Lagoon along the Alagoas state’s Atlantic coast, suffers from both flooding and drought. Modeling the basin’s hydrology can lead to a deeper understanding of these events, and how changes within the basin can affect its hydrology. This stud
In this study four different types of PIR materials have been tested to examine the possibility to use the cone calorimeter (ISO 5660) as a screening tool to evaluate the fire properties of the insulation. As such, manufacturers can be able to make a quick control of the insulation without having to spend resources on full scale testing. One of the materials was from an FM-approved (standard 4880)
Religiös omskärelse på pojkar är ett ingrepp som är förekommande över världens alla hörn, liksom i Sverige. Omskärelsen sker oftast när pojken är ung och därav är det i de flesta fall vårdnadshavaren som beslutar att omskärelsen ska ske. Omskärelse är att betrakta som ett utryck för vårdnadshavarens religionsfrihet och dennes rätt att föra över sin tro på sitt barn. Denna rätt innebär dock en inskReligious circumcision of males is a procedure that is widely occurring all over the world, including Sweden. The circumcision happens often when the boy is very young and therefore, it is usually the guardian that takes the decision about the child undergoing the procedure. Circumcision can be considered as an expression of the guardians religion and as theirs right to transfer it onto their chil
The valorization of lignin offers sustainable and renewable products and materials. For that reason lignin needs to be further analyzed although the various challenges this process implicates. The major obstacles in this field are lignin’s chemical heterogeneity, all the modifications in lignin’s chemical structure owing to its extraction method and purification process and the lack of appropriate
In this thesis I examine how two variables: closeness and the TP-share (two-party-share) of votes impact turnout in elections. I use data from the 2016 Georgian parliamentary election and its two-rounds of election in the majoritarian districts. This field of research poses a wide variety of methodological approaches. One concerns the definition of the dependent variable, turnout. Instead of only
Analogisk överföring undersöktes hos förskolebarn (24 månader till 55 månader) med en faktoriell tvärsnittsdesign. Analogisk överföring testades direkt efter inlärning eller ett dygn senare med en visuo-spatial uppgift. Vidare testades de kognitiva förmågorna arbetsminne, inhibering, självreglering och verbal intelligens. Studiens hypoteser var att fler barn skulle klara den direkta överföringen äAnalogical transfer was studied in preschool children (24 months to 55 months) with a factorial cross sectional design. Analogical transfer was tested directly after learning and one day later, using a visuospatial task. The cognitive abilities working memory, inhibition, self-regulation and verbal intelligence was assessed. The hypotheses were that more children would pass the direct condition th
The aim of this paper is to evaluate a machine learning technique, Random Forest, to predict default rates for banks in the United States. This study extends the findings of a Random Forest model first introduced by Petropoulos et al. (2017) by extending their model by evaluating a longer sample period and adding macroeconomic variables to analyze how current market conditions impact the predictio
Artificiell intelligens (AI) har på senare tid fått en otrolig uppmärksamhet. Det tröttsamma arbetet med att manuellt koda in lösningar i ett program har ersatts av att lära programmen att hitta egna lösningar; detta är en AI-teknik som kallas för maskininlärning. Sådana program tränar upp förmågan att känna igen mönster eller anomalier i data, vilket kan användas för allt från att köra bilar tilMachine learning projects are often constrained by data that is messy, scarce, sensitive or costly to produce. These are issues which could be mitigated by synthetic data. This thesis tries to improve Swedish license plate localization in images by synthesizing images through superimposition, a process that produces data cheaply and in abundance. A generative process algorithmically creates imag
Rätten till abort är idag ett aktuellt ämne som är föremål för mycket debatt runt om i världen. I Sverige har vi idag fri aborträtt, förutsatt att graviditeten inte är för långt gången, men så har det inte alltid varit. Den här uppsatsen undersöker den svenska abortlagstiftningen ur ett rättsutvecklingsperspektiv med utgångspunkt i lagförarbeten och lagtext. Fokus för uppsatsen ligger på hur abortThe right to abortion is a current issue which is widely debated around the world. The current abortion law in Sweden states that the choice of an abortion is entirely up to the woman. This is an essay about the history of the Swedish abortion laws from a legal development perspective. The material that the essay is based on is mainly abortion legislation and legislative history. The focus of the
Despite ample evidence on the importance of labor market opportunities for women’s bargaining power, the link between public childcare availability and female empowerment has so far been widely overlooked. Using detailed survey data on household dynamics, this paper investigates the impact of the Mexican childcare program Estancias Infantiles para Apoyar a Madres Trabajadoras on women’s decision-m
In 2007, Mexico City legalized abortion in the first 12 weeks of pregnancy. By doing so, it became the first and only state in Mexico where abortion on demand is legal. In this paper, I use this natural experiment to estimate the effects of abortion legalization on child and maternal health. I perform Difference-In-Differences estimates using information from all births and deaths occurred between
Demographic transitions are something that every country goes through, however do countries do it at different times. The Western world and Japan are today facing aging populations, developing countries of Africa are still facing high mortality, high fertility rates and booming populations while countries of South Asia and South America are somewhere in between. The demographic diffusion sets up a
Marine protected areas (MPA) have been widely used the recent years, as an alternative to the traditional management tools, in order to increase the yield and the health of a stock. The present study shows how cod population in Öresund would respond under different spatial and temporal MPA and how they will affect the gill-net fisheries in the area. For that reason, a simple model, based on logist
Previous research has focused on the correlation between CSR and returns, whilst considerably less efforts have been undertaken to investigate whether CSR affects a company’s valuation. Therefore this paper focus on investigating the correlation between these two variables. This is done by comparing valuation multiples of constructed indices consisting of bad and socially responsible companies to
The purpose of this thesis is to discuss the reasoning behind the prominence of resilience building in Malawi’s development strategies, how resilience building is performed in Malawi, and what the potential and consequences of resilience in Malawi might be. In observations of a resilience building project and interviews with development practitioners, it was found that resilience had become promin
The aim of this essay is to study if the Chicago Board of Options Exchange’s volatility index VIX can be used as an indicator on the stock market, and if an investor can make a profit on portfolios by using a volatility strategy based on VIX. The study is based on nine volatility strategies that are tested on four different portfolios containing stocks from Mega Cap, Large Cap, Mid Cap and Small C
