Insects can be mapped using a method called Scheimpflug Lidar (LIght Detection And Ranging). Sending out light in the near infrared range and detecting the backscattered echo, it is possible to resolve flying organisms in range and time. Insect observations can be distinguished from the background signal through adaptive thresholding. The detected signal will contain two components; one from lig
The main purpose of this thesis is to present and analyse the Swedish sixteenth-century Catholic priest Andreas Servius’ prayer book Någre Christilige och Catholische böner printed in the Silesian city of Neisse year 1593. The general questions of the study are: which where the main sources of the prayers found in this prayer book? What characteristics typical for the period’s piety can be found i
According to the Environmental Protection Agency (2016) food production has a big impact on the climate, and a big part of the food gets wasted as garbage. About 91% of the food that the stores waste is still eatable (Naturvårdsverket, 2014). The government has set a goal to reduce the food waste with 20% until 2020 in comparison to 2010. In present days there’s a lot of research on how to maintai
With the increase in computational power, deep learning algorithms have become an active field of research over the last 7 years. These data-driven machine learning algorithms have produced good results in many applications, image analysis being one of them. Today, many image analysis tasks in the medical field are done manually, taking valuable time and effort from professionals. Automating some
In an uncertain future, flexibility and ability to adapt are recognized as important factors in avoiding errors, but also discover new ways of handling urban problems. This thesis examines how standardized wooden modules can be used to modify, manipulate and reinvent public space. It also investigates how flexibility in design could help to involve communities and individuals in reshaping and recy
The objective of this report was to investigate different types of glass when exposed to heat radiation from a typical fire in a dangerous goods carrier. The purpose was to evaluate if tempered glass could be used in facades instead of the more expensive fire resistant glass. Experiments were made in a cone calorimeter where different thicknesses of laminated, tempered and fire resistant glass wer
Huge amounts of greenhouse gases continuously released into the atmosphere is of large global concern. Carbon dioxide makes up a large part of released greenhouse gases. Especially the aircraft industry, which is experiencing a steady annual increase as air travel grows in popularity. This business sees 72% of all its combustion products in aircraft exhausts to be carbon dioxide. Swedavia, a compa
One of most ancient food preservation methods is freezing because there are not caused significant changes the sensory characteristics and nutritional value of foods. Last decade, have been made great steps for the optimization of freezing tolerance of fresh vegetables, fruits and species. Cold injury occurs when the cells are exposed to temperatures lower than 0oC. Cold injury is a consequence of
Inom socialtjänsten råder idag en hög personalomsättning bland socialarbetare, mer specifikt bland socialsekreterare. Tidigare forskning gjord bland socialsekreterare syftar främst till att undersöka orsaken till detta genom att hitta en förklaring till varför de väljer att lämna sin arbetsplats. Syftet med denna studie däremot var att undersöka vad som gör att socialsekreterarna, mer specifikt er
Interactive web-GIS tools play an important role in determining disaster risk assessment which ultimately result in reduction of unexpected damages, cost and saves millions of lives. Disaster management practitioners largely benefited information at their disposal about location where possible incidents are eminent, anticipate the impact and project possible outcomes to help mitigate and organize
The study circle is a cultural and educational phenomenon that has fundamentally affected Sweden and continues to do so even today. The present study investigates the Swedish study circle as a medium. This is done by looking at the notions about what the study circle would be during its early years (1902-1922), through the Swedish Good Templars and Oscar Olsson, also known as “the father of the st
Hafnium dioxide (HfO_2) based thin films doped with various dopants (Si, Ge, Al, Gd, Sr, Zr) have been found to exhibit ferroelectricity. These dopants were found to stabilize the III orthorhombic phase in the hafnium oxide based thin films. This characteristic enables and allows various applications ranging from Non-volatile memory, Ferroelectric Field-Effect-Transistors, to Negative Capacitance
Examensarbetet har utvecklat en metod för att estimera den fraktala dimensionen från Transmissions Elektron Mikroskop (TEM) bilder av sot aggregat som skapats med hjälp av en mini-CAST sotgenerator. Det är ett underbestämt problem att estimera den fraktala dimensionen, en 3D egenskap, från 2D bilder. Lösningen är syntetiserade TEM bilder som baserats på projektioner av numeriskt simulerade aggregaIn this master’s thesis a method for estimating the fractal dimension from Transmission Electron Microscope (TEM) images of soot aggregates has been developed, and also applied to TEM images of soot sampled from a mini-CAST soot generator. The problem to estimate the fractal dimension, a 3D property, from a 2D image is undetermined. To solve this, TEM images were synthesised based on projections o
Anxiety disorders and obsessive-compulsive disorder among women in the postpartum period are understudied and their impact upon maternal functioning is poorly understood. There is evidence that individuals with greater levels of psychological flexibility (the ability to persist in valued domains of living despite the presence of negative emotions/thoughts/sensations) and higher levels of social su
Abstract Sedan 70- och 80-talet har det forskats kring manligt och kvinnligt språk, främst genom samtal. Forskare har kommit fram till att män och kvinnor har olika samtalsstilar och att olika stereotyper finns rådande manligt och kvinnligt språk. Syftena med den här studien är att undersöka podcastlyssnares attityder till språket i podcaster i allmänhet och i synnerhet manligt och kvinnligt språk
This work presents the notion of free groups and the definition of a group using generators and relations. We use the Todd-Coxeter Algorithm in order to solve the coset enumeration problem for the finitely presented groups: $D_4,\, A_4,\, A_5,\, S_3,\, S_4,\, S_5,\, PSL_2(7),\, PSL_2(9)$. Then we use these presentations in order to prove the exceptional isomorphisms $A_5\cong PSL_2(5) \cong SL_2(4
Ungdomsspråk har studerats sedan senare 1900-tal. Ulla-Britt Kotsinas (1984) och Lars Gunnar Andersson (1985) finns bland de forskare som beskriver vilka funktioner som ungdomsspråket har bland ungdomar, bland annat skriver de om hur slang och svordomar kan användas som grupptillhörigehetsmarkörer. Slang, svordomar och ungdomsspråket generellt har en tendens att förändras och förnyas vilket gör de
In last decade, the lighting industry significantly changed with the development of light emitting diodes (LEDs) and their corresponding penetration of the market. The new technology increases energy efficiency and longevity compared to other types of lamps. As a result, LEDs can improve the sustainability performance of cities and towns, contributing to the mitigation of climate change and cuttin
Solar radiation is affected in a variety of different ways through the atmosphere and on its way down to the Earth’s surface. Clouds are the main factor in this attenuation of solar radiation, but aerosols, ozone and other different gases have a significant impact too. Understanding these processes is fundamental to solar forecasting. However, the atmosphere is constantly changing, which makes for
