Forskning har visat att uppgifter i prov inverkar på vad elever lär sig genom deras förväntningar på vad testet ska innehålla (Virta, 2004). Boesen (2006b) konstaterar att uppgifter i nationella prov påverkar lärares undervisning vilket indirekt också bör inverka på vad elever lär sig. Lithner (2008) menar att det finns risk att en elev som använder ett imitativt resonemang i alltför hög grad vid lösning av matematikuppgifter får sämre matematikkunskaper. Genom att som lärare förse eleven med uppgifter som kräver ett kreativt resonemang, i vilka det inte är möjligt för eleven att använda ett imitativt resonemang, bör en sådan utveckling hindras. Syftet med detta examensarbete är att med ett klassificeringsverktyg tidigare använt av bland andra Boesen, Lithner och Palm (2005) och Bergqvist (2007) undersöka alla 85 matematikuppgifter i PISA 2003 med avseende på vilken grad av matematiskt kreativt resonemang som krävs för att lösa dem.

En applikationsserver agerar i regel som en förmedlande server i ett tre-skikt-system med en webbserver på ena sidan och en databasserver på andra sidan. De används för att komma åt funktioner i en databas med hjälp av program skrivna för just den applikationsserver som används. På Lantmäteriets huvudkontor i Gävle använder man sig i dagsläget av 5 stycken olika applikationsservrar, vilket medför stora kostnader i bland annat licenser, support och kompetensutveckling. I detta arbete undersöks skillnader i pris och funktionalitet mellan de aktuella applikationsservrarna samt hur man på bästa sätt kan minska kostnaderna för Lantmäteriet genom att sätta upp ett mål där applikationsservrarna används på ett effektivare sätt. För att ta reda på detta har jag intervjuat personer inom Lantmäteriet angående det nuvarande problemet och tagit reda på hur man kan göra för att möjliggöra en utfasning av en eller flera applikationsservrar.

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Sweden recently changed the national regulation of chimney sweeping. This study has two purposes. The first purpose is to evaluate the effect of this reform to see if the new regulation has led to an effect in terms of increased chimney fires in single-family houses and for the wood-burning and oil-burning stoves, respectively. The second purpose is an updating of a previous study (Mattsson 1994) of analysis of society´s benefits and costs of different alternative sweeping frequencies for wood-burning and oil-burning stoves. This study also has a secondary purpose to examine the extent to which the local sweeping rules vary with climate conditions.  Mattsson, based on his results, proposed that the sweeping requirements for oil-burning stoves should be reduced from twice a year to once every second year and for wood-burning stoves the sweeping should be reduced from four times to once each year.

The main purpose in this degree thesis is to investigate changes in performance when introducing a newly produced Real-Time database in one of CC Systems products, the Diagnostic Runtime Engine, DRE. The thesis is a collaboration between CC Systems, creator of DRE, and Mimer AB, developer of the Real-Time database.The result reveals that the time spent on database access is considerably lesscompared to the originally used database. The research has lead to several additional requirements on the real-time database and these are presented as part of the result in this thesis. The additional features will help making the product more suitable for DRE and similar applications.Additional research is required to be able to recommend the use of this product or not. Primarily the performance in another operating system, Windows CE, but also the introduction of additional features should be investigated.

Den här magisteruppsatsen analyserar domen mot Microsoft i EG-domstolens första instans. Domen fastställde att Microsoft genom användningen av kopplingsförbehåll, missbrukat sin dominerande ställning enligt artikel 82 i EG-fördraget. Kopplingsförbehållet i det aktuella fallet bestod i att Microsoft uteslutande sålde två separata produkter tillsammans, operativsystemet Windows och mediaspelaren Windows Media Player. Före Microsoft-fallet tillämpades inom EG-rätten ett per se-förbud mot kopplingsförbehåll, vilket innebar att de automatiskt ansågs olagliga utan att effekterna av det individuella kopplingsförbehållet utreddes. Kopplingsförbehållet i Microsoft-fallet ansågs däremot ha en så komplicerad karaktär att en vidare utredning var nödvändig.

Background: Enterprises often refer to their employees as ?Our most valuable assets? in annual reports and other written statements. In reality, employees are seen as an expense rather than an asset in annual reports and the voluntary disclosure is often insufficient. Human capital disclosure has been discussed through decades and the latest topic in voluntary disclosure is called integrated reporting. Knowledge firms should disclose more about their employees than industrial companies due to the fact that the employees are a considerably more important asset to these types of enterprises.Purpose: The purpose of this thesis is to study the disclosure of human capital, compare the disclosures between knowledge firms and industrial companies, and study the development of the human capital disclosures between the years 2003-2013.

Att välja rätt nätverksoperativsystem för verksamheten vid en omorganisation av nätverket är en svår uppgift. Rätt nätverksoperativsystem är avgörande för hur nätverket i organisationen eller företaget skall fungera. När en omorganisation planeras kan andra nätverksoperativsystem, som kan passa verksamheten bättre, än det existerande systemet väljas. Valet av system beror till exempel på vilken nivå av säkerhet, åtkomlighet, utbyggbarhet, ekonomisk kostnad och driftsäkerhet nätverket skall ha.Denna rapport fokuserar på val av nätverksoperativsystem. Detta görs med avseende på hur det är möjligt att implementera säkerhet, åtkomlighet och driftsäkerhet.

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Porcine circovirus type 2 (PCV2) is a common virus present in most parts of the world. PCV2 has been pointed out as the major causative agent to post weaning multisystemic wasting syndrome (PMWS) that affects pigs after weaning. The clinical symptoms of PMWS are impaired growth, diarrhoea, respiratory problems and increased mortality. At autopsy enlarged lymph nodes with depletion of lymphocytes are commonly found. Since 1991 PMWS has spread all over the world and was first described among Swedish pigs in 2003. Although PCV2 is widespread, only some pigs develop PCV2-related diseases. Why this is and what other factors that are required in order for the disease to develop is yet unknown. The main theories involve other infections, for example PRRS, and management issues but also genetic differences between pigs and/or virus strains have been suggested.

This thesis has been performed at the system development company Verendus System AB, together with the home care company Basic Care Unit (BCU).The thesis has consisted of developing a web based informationsystem for BCU in which they can administrate their business. At the time of writing this thesis, BCU was using a windows-application to administrate their activities, which was both costly aswell as resulting in an unnecessary burden. The aim the thesis has thus been to create a platform-independent information system that simplifies and streamlines BCUs work by being user-friendly aswell as imposing some simplifying features.The students has been developing the system by the help of a work method they themselves developed. The method consisted of working in several iterations that each had several milestones. The method resulted in the students knowing easily when each iteration was finished or not.The thesis resulted in a working platform independent prototype.
