Elevation models are important in many applications in Geographical Information System (GIS), both when applying environmental analyses and in urban planning studies. The production of elevation models has been a difficult and expensive task using traditional surveying techniques. Remote sensing methods for producing digital elevation models have solved the difficult part of the task, which consis

When designing a building one must consider safety aspects. One such aspect is that in the case of an emergency people should be able to efficiently evacuate the building. In this paper we investigate how the width-profile of a corridor leading to an exit might affect the efficiency of evacuation. We model the dynamics of crowds using a continuum model, leading to a one-dimensional non-linear hype

The electricity sector is in the beginning of a large shift from centralized dispatchable production to distributed variable production. With this necessary change, new challenges arise. One crucial challenge is related to upholding the system balance in the power grid. In this master thesis, a Battery Energy Storage System (BESS) has been implemented in an HVDC-system with large amounts of Wind P

Detta arbete är en typfallsstudie vilken behandlar förändringen i ekonomiska incitament vid införande av bidragstak. Förslagets potentiella påverkan studeras utifrån hur många hushåll som

Hur ärvs blomdoft? Att lukta gott är inte bara viktigt för oss människor. I växternas värld är doft, eller de kemiska doftsignalerna, livsviktigt för att kunna locka till sig pollinatörer eller avskräcka fiender. Vi vet redan mycket om hur insekter reagerar på kemiska signaler från växter och hur doft varierar mellan olika växtarter, men fortfarande väldigt lite om hur blomdoft ärvs inom växtpopuOne of the main challenges in evolutionary ecology is to identify the factors and agents that drive diversification. Two of the most diverse groups of organisms on earth are plants and insects, and evidence strongly suggests that the diversification of both groups is driven by the interactions between them. One fruitful way for understanding how these interactions evolve and diversify is to identi

China’s rapid economic development has led to a continuously increasing energy demand and the country is the world’s biggest energy user as of today. The country accounts for around 23% of the global energy production, but 70% of the Chinese energy is generated with coal power and China is the biggest emitter of CO2 in the world. The Chinese government has set a couple of goals to reduce the count

Frågeställning: Syftet med detta arbete var att undersöka om interventioner baserade på ACT respektive buddhistisk meditation har en inverkan på psykologisk inflexibilitet, empati, medkänsla till andra, självmedkänsla samt modern rasism. Till detta hörde en explorativ frågeställning gällande eventuella skillnader i de båda metodernas inverkan på utfallsmåtten. Arbetet avsåg även undersöka hur utfa

The purpose of this project was to investigate the use of microfluidics for X-ray spectroscopy at MAX IV Laboratory. A Silicon and Glass chip was produced, and its suitability for carrying samples in solution was tested. Once the chip was prepared, and successfully integrated onto Balder beamline, X-ray analysis was carried out on a sample of FeCl3 (aq) flowing through the chip. This was contraste

Framtiden för verktyg på bibliotek Ett sätt att minska vår belastning på miljön är att dela saker med varandra. Att kunna låna verktyg och andra prylar på biblioteken - är det ett bra sätt att få fler att dela? Många säger sig vilja dela saker med andra men det är inte lika många som faktiskt gör det. Många av de initiativ för delande som finns idag bygger på delande mellan främlingar, men de flThe sharing of goods and services has a lot of potential in tackling the environmental consequences of consumption. Studies indicate that public lending has advantages over private individuals lending each other necessities. It is therefore important to investigate how public lending can be organised most efficiently. Some Swedish libraries provide tools and other things that are not typically ass

This thesis surveyed existing technologies and research on pedestrian detection systems using video as input. The purpose of the study was to investigate what such a software would need to produce to be relevant for the fire safety engineer in outdoor circulation- or egress applications. The thesis tested a newly developed detection software called Flowity. The software, developed by ÅF Digital So

Humant papillomvirus kanske du någon gång hört talas om. HPV, förkortningen som man vanligtvis benämner viruset med, är mest känt för sin olyckliga förmåga att orsaka hud- och könsvårtor på den mänskliga kroppen. För ungefär ett decennium sedan bevisades det att viruset även är en orsak till utvecklingen av en viss typ av cancer. Denna cancer, som utvecklas i vissa delar av huvudet och halsen, harHead and Neck Squamous Cell Carcinomas (HNSCC) are a heterogenous group of cancers formed in squamous epithelial cells. In a few HNSCC, the cancer is developed because of long-term viral infection. Carcinomas of the Oropharynx (OPSCC) have a high rate of infection of Human Papilloma Virus (HPV), where tonsils (TSCC) have the highest. The aim of this thesis was to evaluate differential expression b

Insekter är en essentiell komponent i många ekosystem. Rollerna som de har är viktiga, vilka inkluderar spridning av växters frön, pollinering och att vara en källa till näring för andra djur. Dock finns aspekter med insekter som innebär hot för människor. Exempelvis kräver malaria cirka 400 000 människoliv per år, en sjukdom som förs vidare av myggor. För att kunna bekämpa sjukdomar som malaria Using laser it is possible to measure the backscattered light from insects. The resulting signal can then be analysed in order to potentially determine the species of the insect. Estimating the fundamental wing beat frequency (FWBF) of insects is important in order do this classification of species, which is an area of research that has been explored previously. In this thesis, the relative phase

In this study, the extraction and isolation of xylan from milled oat hull materials was investigated. Alkali extraction by 2 M sodium hydroxide at 40°C overnight was applied. The yield of extracted xylan was 5%. The extracted xylan was isolated from the extraction mixture by ethanol (99.9%) after neutralization and its purity was checked, resulting in a66% pure product. The semi-purified xylan was

For a city and culture that excels at adding value to waste, Kisumu struggles with a systematic approach for solid-waste management. Food and animal wastes run rampant in the streets while families still cook for hoursevery day using harmful fuels like kerosene, charcoal and firewood. This project takes to heart the insight that if a solution isn’t affordable to those who need it the most — it’s n

Momentvektorering uppnås genom att manipulera bilens hjulhastigheter, i syfte att öka kurvhastigheterna och förbättra trafiksäkerheten. En dubbelkoppling på bakaxeln är en möjlig vektoreringsmetod för en bakhjulsdriven Formula Student-bil. Dubbelkopplingen gör att det inre hjulet kan glida och därmed skapa ett vridmoment kring bilens kropp i kurvans färdriktning. Målet med examensarbetet var att Torque vectoring for automobiles is used to increase cornering speeds and improve road safety by manipulating the car's wheel-speeds. One method of torque vectoring for a rear-wheel-drive Formula Student race car is using a dual-clutch to slip the inner wheel thus create a yaw moment during cornering. The goal of this thesis was to develop and design an electronic control unit to automaticall
