Klimatinducerade fenologiförändringar och dess effekter i näringsväven
The climate affects animal populations through several processes. These processes includereproduction, phenology and the success of hunting. By influencing the phenology of species theclimate also affects the way species interact. If a climate-induced phenology change promotes abasal species to bud earlier in the spring for example, this will affect the links to other species inthe food web due to a time lag in the tropic levels above. This dependence, that a predator has tobeing synchronous to its prey, is called the match/mismatch hypothesis (MMH).
Undersökning av sambandet mellan strålningstemperatur och NDVI i Sahel
Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.
Med för hög musikvolym hör du inte farten
Att tidsperceptionen är påverkbar har tidigare påvisats. Studien syftar till att undersöka huruvida tidsperceptionen påverkar fartperceptionen, med hypotesen att när interna taktgivaren går snabbare uppfattas farten som lägre. 28 försöksdeltagare fick under fyra betingelser (Lugn, Stressig, Egen musik och Tyst) utföra tids- och fartestimationer under bilfärd. Inga signifikanta resultat påvisades ifråga om vare sig tidsperceptionen eller dess inverkan på fartperceptionen. Däremot skilde sig prospektiv estimation av medelfart åt beroende på betingelsen.
Vidareutveckling och utvärdering av operatörsplatser på svenska stridsfartyg
The ability to handle potentially dangerous and hostile situations on a military vesselrequires that the equipment works effectively with the personnel that use it. It is importantthat this equipment can be used by different people. An operator on a military vesselshall be able to handle information about hostile threats, navigation and the steering ofunmanned vehicles. A operator console should therefore be constructed in such a waythat the operator can handle a large flow of information. And the information given bythe technical system should be displayed correctly to facilitate the operators ability tohandle and interpret the information correctly, in order for the operator to make thecorrect decision at any given moment.
Med existensen i ett språkligt rum : Om relationen mellan språk och existens i Göran Tunströms roman Skimmer
Captured in the room of Göran Tunström?s spoken language, fenced behind his barrier of manic words. This essay is about the limit of language and world?s necessity to be spoken to be experience, about telling as a manufacturer of meaning and a subject?s motion between fiction and reality. Based on the novel Skimmer from 1996, my purpose is to identify ?a linguistic room? in Tunström?s narration and show how this room is given an existential character by its temporal and spatial dimensions.
Etnicitet och demokratisering i dagens Rwanda : En kvalitativ studie om etnicitet och demokratisering i Rwanda
The purpose of this study is to explain if the existence of ethnic groups in Rwanda has complicated its democratization and explain what opportunities Rwanda has to be democratized. To fulfill the purpose of the study, I intend to answer two questions: 1) Does the existence of ethnic groups obstructed democratization in Rwanda? and 2) What opportunities has Rwanda to be democratized? To answer the first research question Dahl's theory of subcultures and democratization is used and to answer the second research question van de Walle's theory of democratization is used in the region of sub-Saharan Africa. Literature used in the study are Dahl's Polyarchy and van de Walle Africa?s range of regimes and Freedom House annual reports.
Flavours ? det smakar doft : Upplevelsen av mat och vin i kombination
Inledning: Den vetenskapliga förankringen om mat och vin i kombination är låg. Upplevelsenav en måltid involverar alla de mänskliga sinnena, vilket således har gjort den svår att mäta.Hur stor roll spelar egentligen grundsmakerna och krävs det ytterligare element för att lyfta enkombination av mat och vin till högre höjder?Bakgrund: Förutom smaklökarna på tungan som bildar den grundläggande uppfattningen avdet vi stoppar i munnen, är det främst munkänsla och flavours som bidrar till helheten avsinnesupplevelsen av mat och dryck. Flavours är en kombination av det människan smakar,känner och luktar och det råder oenighet om hur stor vikten av flavours kontra grundsmakerär vid en kombination.Syfte: Författarna avsåg att undersöka vilken betydelse flavours respektive grundsmaker harför upplevelsen av mat och vin i kombination.Metod och material: För att kunna besvara syftet användes kvalitativa fokusgruppintervjuersamt en kvantitativ sensorisk analys i form av Temporal Dominance of Sensations (TDS).Resultat: Undersökningen visade att både fokusgrupperna och TDS-panelen vargrundsmaksorienterade i deras bedömningar. Likväl belyste fokusgrupperna att flavours hadeen viktig roll i att lyfta en kombination och ge den karaktär och komplexitet.
Förändringar av marknadsdesign och deras påverkan på balanshållningen i det svenska kraftsystemet : En kartläggning och analys av de balansansvarigas arbetsgång
A future expansion of wind power in the Nordic power system makes the balancing for the transmission system operator Svenska Kraftnät (SvK) more complicated. Up to the hour of delivery the balance responsible parties? (BRP) makes prognoses and plans, for consumption and production, to help maintain the balance in the electrical grid. How well this is accomplished is affected by the setup of the market design. Therefore SvK has proposed the following possible changes in market design: Increase the imbalance costsIntensify the regulation of imbalancesIncrease the temporal resolution on the different marketsPresent the prices for balancing power in real-timeModify the balancing market to simplify auction of consumption bidsA mapping over the BRPs? processes within planning and trading on the day-ahead, intra-day, and the balancing market has been performed in this thesis.
Kadmium i skånska vattendrag : en metodstudie i föroreningsmodellering
Modelling of pollutants is commonly used in research and at departments working with environmental issues. The need to use large amounts of data when modelling creates the opportunity for more generalised models with lower data demands. Aggregating functions into coarser elements is a sort of generalisation of actual features in nature.A development of a method and a modelling tool called ?KadmiumKalkylatorn? has been performed to model cadmium pollution in rivers in Skåne, Sweden. The water runoff has been multiplied with cadmium standard concentrations based on membership in landuse classes.

Packning i tid och rum : Korologisk förändring och strategier att hantera trängsel i handelsträdgården, bostadsområdet och på begravningsplatsen
The study Packning i tid och rum (Crowding in Time and Space) is a Master Thesis in Human Geography within Geography, presented at Södertörn University College.The aim is to investigate the connections between time and space, more particularly, geographical changes over time. This is done by focusing on the Study of Land use as a phenomenon and on-going processes in demarcated areas. Distinct areas are given special interest, i.e. how they are used. The study deals with three different kinds of sites in three levels of scale: a market garden, cemeteries and a residential area.The main focus of the study is on the cemeteries.
Verifikation av verktyget aspect analyzer
Rising complexity in the development of real-time systems has made it crucial to have reusable components and a more flexible way of configuring these components into a coherent system. Aspect-oriented system development (AOSD) is a technique that allows one to put a system?s crosscutting concerns into"modules"that are called aspects. Applying AOSD in real-time and embedded system development one can expect reductions in the complexity of the system design and development. A problem with AOSD in its current form is that it does not support predictability in the time domain.
De äldres situation i det digitala samhället : Bibliotekets verksamhet för digital delaktighet
This thesis deal with how seniors treat and view the digital world, what their information seeking process looks like and what they perceive as the major obstacles regarding the usage of IKT and the Internet. The experience of the seniors is put in relation to how Uppsala City Library is carrying out the task to increase digital participa-tion. This operation is part of the Digidel network which during the preceding year concluded their campaign Digidel2013 which aimed to render 500 000 new users digitally participant. Following the campaign Digidel published a report on how to further work to increase the digital participation derived from the experience gath-ered from Digidel2013. This report is discussed and put in relation to the proposed measures of Jan A.G.M.

Den stolte bilbyggaren : En studie om lönearbetets betydelse för delaktighet och identitet
The purpose of this study is to find, understand and discuss the experiences of former employees at SAAB, and present how this can be understood according to my core theoretical concepts, which are participation and identity. The questions asked in the study are based on how the labor is described, characterized and what comes forth as valuable, which is compared to absence of labor work.First, labor is described in an historical and social context, and at the same time related to the core theoretical concept. Second, the methodology chapter is presented, which mainly consists of 11 observations and 10 interviews. Third, the chapter regarding former theory leads to an analysis model, which is used on the empirical material of the study.The result shows that labor work at SAAB primarily is described as important for socializing, security and the possibility to be independent. The tasks at SAAB are described as backbreaking and monotonous, while the lack of labor work influences the physical and mental wellbeing.
