Tvåvägsautentisering är en teknik som möjliggör användning av tjänster säkrare genom att addera ett extra lager av säkerhet. Ämnet är ett högst relevant område att studera då användningen av datorer och mobila enheter ständigt ökar. Informationen sprids över fler enheter och fler attackytor skapas. Denna studie undersöker användningen, attityden och kunskapen inom ämnet tvåvägsautentisering bland tekniskt studerande ungdomar. Utifrån en konceptuell modell täcks alla aktiviteter som anses vara relevanta inom ämnet tvåvägsautentisering bland ungdomar.

My essay is an examination of the poet Mina Loy and two poems that are essential in her authorship, these poems also represents a thematic entrance to Loys life and literary concepts. On the basis of Gunnar Harding preface and translation of selected poems from the collection Lunar Baedeker, I have chosen to look further at the poems Lunar Baedeker and Songs to Joanne, poems that accommodate contexts of an esthetical and linguistic complexion.Using terminology from the philosopher Gilles Deleuze as method for analysis, enabling an examination which proceeds from the concepts of nomadism, deterritorialization and line of flight. In the consideration of Loys modernistic and woman ?becoming, a situational and relational context is introduced which includes references to feminism, cosmopolitism, futurism, modernism, Dadaism as well as to acquaintances of Gertrude Stein, Djuna Barnes, F.T. Marinetti and Isadora Duncan.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

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).

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
