Datorbaserad bedömning i språk forskningsläge, erfarenheter och implikationer

To support uniform and fair assessment of Swedish students? English language competences, mandatory National tests are provided both for secondary and upper secondary education. The current thesis may be seen as a contribution to the further development and validation of these tests, with regard to the likely introduction of computerized testing methods. The aim is to gain further knowledge from current research in the field, to study and elucidate international experiences of implementation, and to gather and analyze feedback from students and teachers. Based on my findings, some tentative conclusions will be drawn, and recommendations made concerning future developments.

Energianvändning i serverhallar: energiflöden och kylning

This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.

Att gestalta en socialt hållbar begravningsplats

This thesis aims to present the essential background on how to perform climate changeimpact assessments, and to present the results from a climate impact assessment on waterbalance and nitrate leaching for an arable Swedish soil. The soil is a sandy soil in southwesternSweden, grown with spring cereals. This study is meant to be a benchmark example,and cannot be seen as a regional or national assessment for Sweden, rather as an approachto present and analyze the most important parts of these kinds of assessments.A dynamical simulation model (COUP, Jansson and Karlberg, 2004) was used for thisstudy. The model was parameterized and calibrated against data from an experimental site,located in Mellby in Hallands county, south western Sweden. Measurements were carriedout between 1st of April 1988 and 1st of April 1991.

Den passionerade arbetssökaren : En textanalys av jobbannonser i svenska data och tvspelsbranschen

Data och tvspelsbranschen är mansdominerad och har fått en hel del uppmärksamhet i media på senare tid. Dels för bristen av kvinnor som arbetar inom den och dels för kvinnosynen som uttrycker sig i spelen. Vi kommer använda ordet spelbranschen som synonym till data och tvspelsbranschen i resten av uppsatsen. Tidigare forskning har visat att utformningen av jobbannonser kan vara en bidragande faktor till att kvinnor inte söker sig till vissa arbeten. I denna studie har vi undersökt om jobbannonserna i spelbranschen i Sverige är maskulint könskodade och hur detta i sådana fall formulerats.

SPICA - ARISTO JÄMFÖRELSE studie av analysprogram med avseende på spånningskollaps i elektriska kraftsystem

Safe operation of a large synchronous power system as Nordel is not an easy task.There are several aspects to take into consideration. This thesis focuses on the problems due to voltage collapses in a transmission system.The ability to foresee an upcoming collapse is vital to maintain stable operation of the grid. The grid operator at Svenska Kraftnät (SvK) uses the computer program SPICA to predict the maximum transfer limit at specified transfer sections. SPICA uses actual states from the grid to predict the transfer limitation, and a quarter later a renewed estimate is produced and so on. This means that the operator can se his transfer limits vary every fifteen minutes.Our task in this project is to validate the accuracy of the limitations obtained by SPICA.

Conclusion: The conclusions of the thesis imply, that in order to make a loyalty program successful, it needs to firstly be conven-ient for the customer; easy to join, and provide an easy and time efficient display at the point-of-sale.

Integritet och sa?kerhet inom den digitaliserade sjukva?rden. : Med perspektiv utifrån patientdatalagen

The digitization of patient data and medical records used by the healthcare-industry in Sweden is rapidly developing. However; developing and changing things in this field is not an easy task because of the circumstances surrounding it. Digital systems intended to process, and hold, sensitive personal data, such as medical journals, must be developed with laws, confidentiality, integrity and availability in mind to secure that none of this data gets compromised.A complicating factor in regards to this is the fast rate of development within IT in contrast to the much slower bureaucratic process of the justice system. This means that laws and regulations oftentimes aren?t up to date with the newest available technology.With the purpose of establishing set regulations on how patient data should be properly handled the Swedish government enacted the Patient Data Act (sv.

Water balance and nitrate leaching from arable land in a changed climate : a model study

Speltestning ? Med Fuzzy Logic

Vid design av ett dataspel försöker speldesignern ofta skapa banor och fiender som tvingar spelaren att använda olika strategier för att överleva. För att hitta dessa strategier krävs speltestning. Speltestning är tidskrävande och då också dyrt. Den enklaste metoden för att spara tid är då att använda data hooks i spelet och sedan låta testpersoner spela spelet. Data samlas då in under alla spelsessioner och lagras i loggfiler.Med hjälp av data hooks samlades data in till denna rapport.

Regression då data utgörs av urval av ranger

För alpina skidåkare mäter man prestationer i så kallad FIS-ranking. Vi undersöker några metoder för hur man kan analysera data där responsen består av ranger som dessa. Vid situationer då responsdata utgörs av urval av ranger finns ingen självklar analysmetod. Det vi undersöker är skillnaderna vid användandet av olika regressionsanpassningar så som linjär, logistisk och ordinal logistisk regression för att analysera data av denna typ. Vidare används bootstrap för att bilda konfidensintervall.

Intresseavvägningen i personuppgiftslagen - Det kommersiella intresset

Personuppgiftslagen (1998:204) är en lag som syftar till att skyddavåra personuppgifter. Huvudregeln i personuppgiftslagen är attsamtycke krävs från den som personuppgifterna tillhör för att de ska fåbehandlas. Till denna huvudregel finns det dock ett viktigt undantagsom stipulerar att om behandlingen är nödvändig får den utföras utansamtycke, om exempelvis ändamålet uppfyller ett berättigat intressehos den som ämnar behandla uppgiften som väger tyngre än denenskildas intresse av skydd för den personliga integriteten. När ettsådant berättigat intresse ställs mot den personliga integriteten blir enintresseavvägning nödvändig för att avgöra om behandlingen skallvara tillåten eller ej. Det berättigade intresset som upptar dennauppsats är det kommersiella intresset, som exempelvis omfattar ettföretags intresse av att behandla personuppgifter för att via direktmarknadsföring marknadsföra sina produkter.

Uppskattning av Ytkurvatur och CFD-simuleringar i Mänskliga Bukaortor

By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.

"Snipp snap snut, nu tog tiden slut" : En analys av användares medvetenhet kring integritet på mobilapplikationer

This study focuses on the integrity of students at Uppsala University that has used the university?s network, UpUnet. We?ve studied their opinions with the use of questionnaires that cover questions related to privacy and awareness about logging of data traffic.The results showed that more students than our hypothesis suggested were unaware of the surveillance on the network, and the majority of these also had a negative opinion towards logging of data traffic. However, we found that there were several relations between how the students responded on our questionnaire, and we?ve presented these in the analysis chapter towards the end of the essay..

Högre krav men mindre tid : en jämförande studie av lärares upplevelser av fördelningen av arbetstiden

Purpose: The purpose of this study is to find out how much influence underlying factors have in connection to the internationalization of Born Global firms. Methodology: This study has a qualitative approach in which data is obtained mainly through interviews and secondary data which consists previous theories about the internationalization in small and medium sized firms and recent theories that entitle these firms as Born Global. Conclusion: Based on the existing theories and the qualitative data, we have concluded that the underlying factors for the Born Global firm?s internationalization are abilities and opportunities to create insidership in relevant networks. The most crucial underlying factors for Born Global firm?s internationalization are the ability to create processes to break old patterns of thoughts and the ability to ally with right partners. .
