This thesis investigates the use of artificial neural networks for classifying Raman spectra of partially degraded cellulose samples by fungal species. A multilayer perceptron configuration of 4 hidden layers and 128 hidden nodes was able to classify a set of 60 samples with an overall prediction accuracy of 0.55. Results show that data resolution is an important factor when optimizing classifier

An ongoing trend the last couple of years has been the intense reporting of an increased amount of deliberate vehicle fires in Sweden. As the overall assumption in society is that the number of deliberate vehicle fires is steadily increasing, a statistic model trying to investigate this was made. In 1998, the share of deliberate car fires were estimated to 12%, the same number in 2015 was 38%, ind

Ny antibiotikakandidat upptäckt i levern hos djuphavsfisken Havsmus Två tidigare okända ämnen med antibiotisk aktivitet har renats fram ur havsmusens lever. I havsmusens lever och giftblåsa har också ämnen med toxiska aktiviteter hittas. Dessa substanser kan vara av intresse för framtagning av smärtstillande och bakteriedödande läkemedel. Penicillinet upptäcktes för 100 år sedan av Alexander FleThe liver oil from C. monstrosa (rat fish) has traditionally been used as a natural remedy in the area around Skagerrak, since it is believed to have a wound healing and analgesic effects. On its back the rat fish carries a vigorous venom spine connected to glandular cells, which secrets toxins. A previous study shows that extract from the liver and venom glands had a cytotoxic activity on A. naup

Today's blockchain applications have been inherently created by and for users who understand the blockchain technology. To improve mass adoption of blockchain solutions, the user experience must improve, and the attention must move to users not familiar with the underlying technology. This dissertation starts with reviewing the main concepts of blockchain technology and examining the UX of dif

I mitt yrkesliv har jag varit verksam i ett antal olika organisationer inom samma bransch, både som anställd och på mellanchefsnivå. Det har fått mig att fundera på dels hur företag som till synes är ganska lika med samma verksamhet och målsättning ändå kan vara så olika? I denna uppsats tar jag utgångspunkt i hur det är att vara mellanchef. Att vara mellanchef innebär att vara den person som befi

Motivation and identity have been vastly investigated within second language acquisition (SLA). These issues are restrained by their complex and dynamic natures, which indicate that they are far from easy to research. The purpose of this essay was to continue traditional areas of research in order to add to empirical knowledge. The attempt was to show that systematic research is necessary in order

Det här examensarbetet har till avsikt att fördjupa och aktualisera kunskapen om vilka skolvägsutredningsmetoder som är bäst lämpade för att klarlägga en förbättrad trafikmiljö för barn. Arbetet består av två huvuddelar: den ena är en litteraturstudie som granskar tidigare kunskap inom området kring skolvägsutredningar och den andra delen består av skolvägsutredning via en digital respektive tradiThe aim of this master thesis is to study differences and similarities between two methods of investigation regarding children’s travel to school; a digital survey and a paper-based survey. This study subsequently collects information from children via these surveys regarding their travel habits, the reason for their modes of transport and how they perceive different factors in the transport envir

Is experimental case study on how to design a modern adventure playground using 3D printing and Recycled materials, as a way of integrating minor newcomers.

Insect pollinators, such as bees, provides us with important ecosystem services. Unfortunately, a decline in key pollinators has been seen globally. Habitat loss and fragmentation, e.g, caused by urbanization, have been pointed out as important driving factors of pollinator declines. However, studies have also shown that species richness of pollinators can be greater in urban than in rural habitat

Georg Pauli belonged to a group of artists known as the Opponents, due to their opposition of the way art education, exhibitions, and allocation of grants was managed by the The Royal Swedish Academy of Fine Arts (Kungliga Akademien för de fria konsterna). Their oppositional work resulted in the formation of the Arts Association (Konst¬närs¬förbundet) in 1886. In a series of books and articles, in

Language anxiety is one of the most difficult issues teachers face in the English classroom today. The area is vast and complex and not much research has been done with a practical focus. This study investigates how the Fogg behavior model can be used to identify foreign language anxiety, and how anxiety affects English learners in a Swedish context. I noticed that there was an inadequate amount o

Automated manufacturing processes are an important component of today’s industries. Assuming the processes are properly maintained they allow for great efficiency when producing various goods. Image analysis can be used as a tool to monitor such processes and evaluate their results. This Thesis treats development of algorithms for automatic evaluation of images acquired using a standardized proce

Att biodiversiteten minskar både regionalt och lokalt är en av vår tids största utmaningar. För att kunna bedriva ett framgångsrikt bevarandearbete i Europa genomförs så kallad biogeografisk uppföljning vars syfte är att övervaka och kartlägga utpekade arters utbredningsområde och populationsstorlek. För detta ändamål är det viktigt med pålitliga standardiserade metoder som är kostnadseffektiva me
