As hybrid vehicles are growing more popular, new challenges for manufacturers arise to achieve good NVH. This master thesis analyzes an electric motor installation at the rear axle on the Volvo V60 Plug-in Hybrid with the goal to lower the noise level in the vehicle compartment. Measurements are combined with CAE-analyses to understand the problem areas and the behavior of the existing installatio
The architectural and engineering trend leads towards greater use of glass in buildings. Growing safety awareness often requires laminated glass. Laminated glass is formed as a sandwich of two or more sheets of glass and a plastic interlayer. Laminated glass can for example be used in stairs, floors, roofs, facades and balcony railings. This thesis deals with the most common interlayer polyvinyl
Ligger fröpredation bakom minskningen av fruktträd i tropikerna? I tropiska skogar samsas fler djur och växtarter om livsutrymmet än någon annan stans på jorden. De gynnsamma förhållandena har gjort det möjligt för evolutionen att skapa många avancerade samspel mellan arterna och bland annat uppskattas det att runt ¾ av trädarterna i tropiska skogar är beroende av djur för spridning av sina frön.The hunting of primates and other mammals as bushmeat are a rising problem in tropical areas, with cascading effects which are only recently beginning to be understood. Numerous studies in forests throughout the tropics has shown declines in the regeneration of fruiting trees adapted to primate mediated seed dispersal and an increase in the regeneration of abioticaly dispersed trees. This shift in
Income inequality in China is a topic widely discussed in the literature. So are globalization, and the continuous increase in the presence of foreign direct investment on the world market. This paper uses data from the Chinese statistical yearbooks, to conduct an empirical analysis, based on panel data, to research if there is a relationship between the increasing levels of inter-provincial i
The purpose with this thesis was to examine why Swedish managers choose environmental consultants to a significantly lower extent than auditors as sustainability report assurance provider.
Spatial analysis, playing an essential role in data mining, is applied in a considerable number of fields. It is because of its broad applicability that dealing with the interdisciplinary issues is becoming more prevalent. It aims at exploring the underlying patterns of the data. In this project, we will employ the methodology that we utilize to tackle spatial problems to investigate how the cell
Jakten på fisken i Ringsjön Många vill veta var i sjön fisken finns när man ska fiska och nu finns det en teori som berättar hur fisken sprider ut sig i en sjö. Fiskar sprider ut sig så att områden med mer resurser har fler individer jämfört med delar med mindre resurser. Detta gör att det finns mer individer som konkurrerar om mat i resursrika områden medan i områden där det är svårare att hittaMovements occur among many different organisms and a suggested theory about the pattern of these movements is called the Ideal free distribution. It states that individuals in a complex area with different quality of the habitats will distribute themselves proportionally after resources in the different habitats, so that they can maximize their fitness. Lake Ringsjön is a complex lake, which consi
Surface coatings are used in many applications. An advantage of coating a surface using particles from a dispersion is that a change in, for example, temperature can control the compactness of the surface coverage. In this research the competition between bulk aggregation and surface adsorption of colloidal silica spheres was investigated. The system used contained aqueous dispersions of industria
This master thesis aims to gain an understanding about how managers and members in an organization perceive observed employee silence (intentional withholding ideas at work) and attribute meanings to it. In addition, it aims to reveal, in what situations observers are not able to identify the intentional silence. Organizational culture, sensemaking and power relations and U-turn in criticism are t
This essay's primary purpose is to find out if there are any typical features that can be seen in the expensive homes belonging to the upper class. What makes these homes feel specifically luxurious? Is there something we can call "luxury" that is timeless? I have analysed two interiors from two different eras, both inhabited by the upper class. The concept of luxury and "good
Abstract Bacteria exist everywhere, some of which are harmful to humans. To prevent spread of diseases and contaminants, handling, preparation and production of food are strictly regulated. In the geriatric care, food is served to very sensitive people with diseases or weak health and therefore it is very important that food and hygiene standards are high. In the municipality of Kävlinge some sho
Anaerobic digestion is widely used for the treatment of industrial wastewater for its cost benefits effects and potential production of renewable energy. Therefore, industries/industrial plants are installing and developing their wastewater treatment plant with this method for treating the discharged wastewater to get renewable energy source for the production of heat and electricity. To investiga
In the recent decades, one of the most phenomenal changes in many universities in Western countries is the dramatically increase of students from China. Subsequently, the thesis author mentioned that general view concerning educational tourism associates educational tourists with the international students’ mobility. This has emerged as an important part of the university students’tourism market.
The nitrification process is known to be the most sensitive link in biological nitrogen removal used in many wastewater treatment plants. Many different inhibitory substances can disturb these sensitive bacteria and in that way cause reduced nitrogen removal. The aim of this study was to investigate the nitrification inhibition in a laundry wastewater before and after internal chemical treatment.
Populärvetenskaplig sammanfattning: Hur ska vi fiska torsk i Öresund? Debatten om man ska fiska torsk i Sverige och i så fall hur har pågått under en längre tid. Detta för att torsken har minskat kraftigt efter år av överfiske. I Öresund har torskbeståndet dock klarat sig bättre, då trålfiske i sundet är förbjudet för sjöfartens skull. Här är torsken även ganska stor jämfört med övriga ÖstersjönThe objective of this study was to analyze recreational and commercial fishing and their respective effect on revenue and catches in the cod fishery in Öresund. This was done by including both recreational and commercial fishing in a bio-economic model. The results from the bio-economic model suggest that more fishing effort is being put in on the cod stock than what is most cost effective, by bot
Populärvetenskaplig sammanfattning: Kartläggning av långbensgroda på Öland Amfibier världen över har minskat kraftigt sedan1970-talet. Orsakerna är många men flera är okända. Fem av tretton amfibier i Sverige är hotade och åtgärder genomförs för att öka arters populationer. Biogeografisk uppföljning är ett nationellt program för uppföljning av amfibier som kan upptäcka förändringar i en arts popAs a result of e.g. habitat loss and diseases, a global decline of amphibians is a fact. In order to prevent further declines and to improve the conservation status for amphibians in Europe, the member states have to report the status for amphibians every sixth year to EU. In Sweden, the County Administrative Board in Scania is responsible for coordinating the biogeographic monitoring of amphibian
Syftet med denna rapport är att granska och utvärdera den praxis som finns idag i fråga om hur kommuner hanterar anslutning av industrier och verksamheter till det kommunala, REVAQ-certifierade reningsverket. Anledningen till detta är att det slam som uppstår vid rening av avloppsvatten har ett högt innehåll av närsalter. Detta innebär att slammet kan nytt-jas som gödningsmedel, förutsatt att det
The aim of this thesis is to investigate double taxation treaties impact on intermediate trade. Based on a panel data sample of five partner countries and 39 reporter countries over the period 1990-2012, the impact of signing DTTs on imports of intermediate trade in goods between two countries is analysed through a Gravity model. The main results show that DTT signing is associated with an increas
