Användarupplevelse av ett komplext infotainmentsystem i en bil. En verklighetsbaserad studie av gränssnittet mellan människa och fordon

In recent decades here has been a huge development in information technology (IT), where we humans are increasingly using IT in our daily lives, ranging from social media to music streaming services; this has also been a reflection of the technologies developed to our cars. Infotainment systems have become an increasingly regular feature in modern cars where the high degree of integration such as navigation, mobile and Internet has become more common and more sought after. Despite this, relatively little research problemized User Experience of a complex infotainment system in a car. This study thus has the intention to consider the relevance of reality based tests by examining how the user experiences a complex infotainment system in a car. We asked ourselves; How do the user experience a complex infotainment system in a car? We conducted our qualitative study, an interview with researchers in the field of vehicle and road safety and designed a number of system-related activities in a test session where we observed three users.

Gas som bedövningsmetod vid slakt av slaktkyckling :

Electrical stunning is the method that has been used in Sweden to stun broilers prior to slaughter. However, for reasons of animal welfare and meat quality, research has been made in the EU to develop new stunning methods. Gas stunning is now regarded as the best alternative. In this study literature has been reviewed with focus on different gas stunning systems and observations have been made at two different slaughterhouses regarding animal welfare before, during and directly after stunning. At one slaughter plant carbondioxide was used in a two-stage system where the birds were standing on a conveyer belt during the stunning procedure.

Does tree removal along railroads in Sweden influence the risk of train accidents with moose and roe deer?

After the storm Gudrun in 2005, the Swedish Transport Administration started clear-cutting of railroad corridors to reduce the risk of trees falling down on the tracks. Simultaneously, train accidents with moose and roe deer have become more frequent and the costs for consequent delays and repairs of engines are of growing concern. There is reason to assume that tree-clearance of railroad corridors may have contributed to an increase in number of accidents with moose and roe deer because the cleared areas provide attractive forage and thus may attract wildlife. The objective of my study was to investigate how clearing of trees affected the number of accidents with moose and roe deer. I compared deer-train collision frequencies before and after clearance of the selected railroads and compared these with uncleared control railroads in a BACI (before-after control-impact) approach.

Aktiv ventilstyrning

To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.

Att arbeta som sjuksköterska med patienter med TBC : en litteraturstudie

Syftet med denna litteraturstudie var att beskriva sjuksköterskans arbete med patienter med TBC (tuberkulos) och sjuksköterskors uppfattningar av risker som de utsätts för i vårdarbetet i kontakten med patienter med TBC. Sökning av vetenskapliga artiklar gjordes i databaserna Medline via Pubmed, Science Direct, Swedmed + samt Cinahl. Studiens huvudresultat utgjordes av tre huvudkategorier; Ssk bidrag till minskad smittspridning, omvårdnad vid TBC och Sjuksköterskans risker i arbetet. Ekonomisk levnadsstandard samt utbildningsnivå visade sig ha stor betydelse för utbredningen av TBC. Det sociala umgänget är en viktig del i sjukdomsförloppet eftersom patienterna känner att nära och kära undviker dem.

Google digitaliserar bibliotekssamlingar En analys av hur biblioteksvärlden reagerar på Google Book Search

The wide spread of the Internet and new information technologies in recent years has come to effect how libraries manage and disseminate information. Search engines like Google are widely used by people who often find the information retrieval systems of libraries to be too complicated. In 2004 Google announced plans to digitise five major library collections. Organisations representing the publishing industry and authors have since then filed lawsuits against Google claiming that Googles scanning of library books infringe the rights holders copyright. Due to Googles potential impact on libraries this thesis aims to examine how Googles digitisation project, Google Book Search, has been received in the library community.

Stålkonsumtion och ekonomisk utveckling i Kina: En ekometrisk analys

Det har länge varit känt att stålkonsumtionen har en stor betydelse för samhällsutvecklingen. En ökad stålkonsumtion betraktas ofta som en indikator på ekonomisk utveckling. Syftet med denna uppsats är att undersöka hur Kinas stålkonsumtion förhåller sig till den snabba ekonomiska utvecklingen och i vilken inriktning går sambandet, dvs. är det den ekonomiska utvecklingen som driver stålkonsumtionen eller vice versa. Undersökningen omfattar perioden mellan 1970 och 2011.

Kim Jong Il - Docka eller dockmakare?

This paper has bearing on the subject of foreign policy analysis and decision-making,but is nonetheless important to peace and conflict studies due to its emphasis onnuclear weapons and deterrence.I have constructed a theoretical framework for the analysis of foreign policydecision-making that I set out to test on a crucial case. The framework iscrosscutting, and takes into consideration four levels of analysis: the system-,regional-, state-, and individual level. It is centred on a key decision maker, andapplies a cognitive approach for determining his or hers belief system through whichthe inputs from the other levels are filtered in order for the decision maker toconstruct a perception of reality, from which the decision is then formulated within.The framework is applied to North Korean and its leader Kim Jong Il. It sets outto explain his behaviour in the matter of their claimed nuclear weapons program, andhis decision to conduct a nuclear weapons-test, getting inside his head trying to figureout why he chose to do it and for what reasons.The conclusion indicates that the basic structure of the framework and its generalapplicability is sound, but that it needs further testing in order to make it perfectly solid..

The potential of entomopathogenic fungal isolates as an environmentally friendly management option against Acanthoscelides obtectus

The bean bruchid, Acanthoscelides obtectus is a major threat to bean production. In Ethiopia, where this study was performed, the damage by bruchids on stored beans has been reported to reach up to 38%. To use the isolates Beauveria bassiana and Metarhizium anisopliae in the management of A. obtectus can be an environmentally safe alternative for controlling the pest. In the present work the aim was to examine if the four chosen fungal isolates, B.

Koffeins påverkan på tårproduktionen

Syfte: Syftet med arbetet var att undersöka om ett intag av koffein kan påverka tårproduktionen med hjälp av Schirmer 1 test.Metod: I det här arbetet deltog 30 personer i åldrarna18 ? 28 år (medelåldern var 22,3 ± 2,1 år) som var uppdelade i två grupper med 15 personer i varje grupp. Den ena gruppen fick 200 ml vatten och 300 mg koffein och den andra fick bara 200 ml vatten. Alla deltagares tårproduktion mättes fyra gånger, en gång före intag, efter intag mättes tårproduktionen efter både 30, 60 och 90 minuter. Tårproduktionen mättes med hjälp av Schirmer 1 test, vilket är en pappersfilters remsa med en graderad mm-skala som hängs fast i deltagarens undre ögonlock, där den absorberar ögats tårar.Resultat: Det fanns ingen statistisk signifikant skillnad (p > 0,05) efter koffeinintag, men det fanns det efter vattenintag på höger öga där tårproduktionen minskning var statistiskt signifikant mellan första och sista mätningen (p = 0,011).Slutsats: Det fanns ingen statistisk signifikant skillnad (p > 0,05) efter koffeinintag.

Att kommunicera naturvetenskap -om hur valet av testmetod påverkar elevers prestationer i naturvetenskapliga tester

Svenska elever deltar emellanåt i nationella och internationella undersökningar där deras naturvetenskapliga kunskaper testas. På vissa frågor i dessa undersökningar har svenska elever fått ett dåligt resultat, få elever gav ett naturvetenskapligt korrekt svar. Syftet med denna studie är att få en bättre förståelse för hur elever resonerar och handlar i en testsituation. Syftet är även att få en uppfattning om hur valet av testmetod och elevers begreppsförståelse påverkar deras prestationer i naturvetenskapliga test. Genom att, utifrån ett sociokulturellt perspektiv på lärande, samtala med elever har jag försökt se hur de resonerade kring naturvetenskapliga frågor.

En kartläggning av målvakters tränings- och matchmiljö inom Svensk elitfotboll

Purpose: The purposes of the current study were to investigate whether there were any differences in the perceptual ability between professional and non-professional ice-hockey players and whether professional players are better at distinguishing, paying attention to and concentrating on what is important during intense physical activity. Method: Twenty male ice-hockey players (10 from both the Swedish first and third divisions) participated in the study. Wingate test were used for physiological measurements while three psychological tests were presented in front of the participants. Stroop, Flanker and Fast counting tests were used to measure perceptual and coping abilities during intense physical activity and the differences between the two groups. Results: Fast counting and Flanker word 2 tests showed a significant difference between the two groups, whereby the professional groups was faster and more accurate than the non-professional group in answering.

Neutral bolagsskatt? : Analys om SOU 2014:40 skapar neutralitet mellan lånat och eget kapital

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.
