RDB2 är en relationsdatabashanterare som har utvecklats på Högskolan i Skövde för att användas i undervisningssyfte. Åtkomsten av data i den nuvarande versionen av RDB2, version 0.93, anses vara ineffektiv. Lagringsstrukturen är uppbyggd med hjälp av en lagringsteknik som kallas hashing. Hashingen påverkar hur datan lagras fysiskt. När hashing inte kan användas måste åtkomsten ske sekvensiellt vilket leder till att åtkomsttiden blir dålig.

Syftet med detta examensarbete är att undersöka årskurs nio elevers matvanor, och betyg i ämnet i idrott och hälsa utifrån genus. Studien genomfördes på två stycken skolor den ena i ett område med lågt socioekonomiskt index och den andra i ett område med högt socioekonomiskt index. Examensarbetet genomfördes med hjälp av information sammanställt från 77 stycken enkäter, betyg och relevant litteratur. Resultat av undersökning visar att det finns viss korrelation mellan elever som lever i områden med högt socioekonomiskt index har högre betyg i ämnet idrott och hälsa och god kosthållning i jämförelse med elever som bor i områden med lågt socioekonomiskt index som har lägre betyg och sämre kosthållning, dock går sambandet inte att säkert fastslå. Resultaten av studien visar att eleverna på skolan med lågt socioekonomiskt index äter mer onyttig mat och betydligt mindre frukost i jämförelse med eleverna på skolan med högt socioekonomiskt index.

The aim of this essay is to contribute to a better understanding of the prehistoric site Flyhov in the province of V?sterg?tland, Sweden and its immediate surroundings from an archaeological perspective. The site contains material artistic and ritual expressions from different prehistoric periods, and its long use-history (from the Stone Age until today) shows that the site, and its remains, has attracted the interest from people in prehistory, in modern times, as well as today. With a point of departure in perspectives derived from hermeneutics and phenomenology the essay examines the site?s prehistoric remains, the use of, and the interest directed towards, the site and its remains during different time- and use-horizons and how these horizons have been affected and intertwined with each other, in a manner where earlier material expressions have affected people and their new expressions.

Om den effektiva marknadshypotesen inte gäller skulle varje aktie handlas över eller under aktiens verkliga värde. Om så är fallet skulle alla index som är viktade efter börsvärde automatiskt överexponeras när en aktie handlas över dess verkliga värde och underexponera när en aktie handlas under dess verkliga värde. Det här betyder att kapitalviktade index är fundamentalt och strukturellt bristfälliga och kommer kontinuerligt övervikta alla aktier som handlas över verkligt värde och undervikta all aktier som handlas under verkligt värde. Efter att läst Robert Arnotts forskningsartikel ?Redefining Indexation? väcktes intresset av att utföra studien på den svenska aktiemarknaden.

This paper concerns the treatment of people at execution places and it is focusing on Gotland and the execution place called Galgberget. The material in the paper comes from Galgberget and a gallow in Denmark called Slots Bjergby. Together with this the laws of Gotland during the medieval and later periods are discussed and also how the archaeological material (especially the buttons) found on the excavation site can help to understand the people buried on the gallow site. The result of the analysis shows that the laws and the material found on the excavation site often tells different things. The punishments are often softer then what the law says.

Denna studie undersöker hur aktivt förvaltade BRIC-landsfonder (Brasilien, Ryssland, Indien och Kina) som erbjuds på den svenska fondmarknaden har presterat i förhållande till respektive jämförelseindex (MSCI) utifrån avkastning och riskjusterad prestation under perioder av upp- och nedgångar 2006 till 2011. Vidare undersöker vi hur BRIC-landsfondernas prestationer har hållit i sig jämfört med index och varandra över tiden. Vi finner att majoriteten av Brasilien-fonderna slår index i både upp- och nedgång, samt håller i prestationerna över tid. Riskjusterat presterar fonderna över index två av tre perioder. Ryssland-fonderna slår index i uppgång, men inte i nedgång.

The county hospital of Dalarna has for the last couple of years carried through a process of digitalization. The result is that within the county it exists image plate systems from two different manufacturers. In an attempt to create a tool for dose optimization and dose surveillance the county of Dalarna would like to investigate if the exposure index from Agfa and Fuji is suitable as a dose indicator. An investigation of the exposure index, S, from Fuji has already been done. This thesis has been continuing the investigation by evaluating the stability of the exposure index, lgM, from Agfa.

The aim of this thesis is to investigate how the indexing of fiction for adults looks like in the public libraries that don?t buy indexed records for fiction from Bibliotekstjänst (BTJ). The questions that I want these libraries to answer is: - Public libraries that index fiction for adults themselves: 1. What tools do they use when indexing?, 2.

The purpose of this study has been to examine whether the bottom fauna of the stream Stensjöån, has been negatively influenced since the harvesting of peat began on the nearby peat moss Skäftesmyr or not. Comparison has been made with the results of index calculations from earlier examinations in the stream, two calculated indexes has been made, Danish fauna index and ASPT-index. The sampling was made with the kick sampling method, SS-EN 27 828. Three locations were chosen for the examination, one upstream from the peat moss, one just downstream from where the brook from the peat moss joins Stensjöån and a third location near the outlet of the stream to the lake Stensjön. The samples were sorted and the found animals identified to the taxonomic level required for the calculation of the two indexes.

Att koppla samman nätverk över geografiskt olika platser har blivit allt vanligare i dagens samhälle. Rapporten kommer belysa olika WAN-lösningar för att göra detta möjligt. De olika lösningar som kommer belysas i denna rapport är att hyra egen fiber, lager2-länk, MPLS och även VPN. Det kommer göras jämförelser mellan dessa lösningar när det gäller kostnad, säkerhet, hastighet och tillförlitlighet. Detta har gjorts med vetenskapliga artiklar och intervjuer men rapporten innefattar även en praktisk tillämpling i form av ett experiment..

AbstractMaster thesis in Business Administration, School of Business and Economics at Linneaus UniversityAuthors: Patrik Larsson and Pontus GislénSupervisor: Håkan LockingExaminer: Sven-Olof CollinTitle: The index effect- a study on Nasdaq OMXS30 and OMXH25Introduction: A significant part of the financial literature is based on the Efficient Market Hypothesis which assumes that prices in the market reflects all available information. Anomalies, such as the index effect, indicate weaknesses in this theory as it has been proved that it is possible to outperform the market using public information. Hence, the index effect can be linked to market efficiency which makes it interesting to study from a theoretical perspective. The mapping of the index effect is also interesting from a practical perspective, as it leads to a better understanding of whether investors and firms should take this anomaly into account.Problem: Is there an index effect, how does it behave and what can explain this effect?Purpose: The aim of this study is to investigate the index effect.

Site fidelity, the behaviour of animals to return to areas where they have been before is a common trait in many species. The Scandinavian moose is known to show fidelity to its range, but to what extent, is little known. The landscape in Sweden changes in a predictable and unpredictable way and hence gives the opportunity to test the existence of fidelity. I used the kernel Brownian bridge method to estimate the home ranges of individual moose over consecutive years and estimated the overlap at the home range level. I also used Euclidian distance to look on calving site fidelity.

The primary ambition of this degree thesis is to create a representative outdoor environment that surrounds Malmö Konsthall (Malmö art center) which reflects the amazing inside of the artcenter. During this work it has become more and more obvious that Magistratsparken, which is situated right next to the artcenter, ought to be incorporated into this project. This thesis aims to examine the possibilities of implementing temporary outdoor artshows on this site. First; is there any interest in exhibiting art at this site? And secondly, if that is the case, what are the spatial needs and how can you prepare the place for future exhibitions and still keep its flexibility for different kinds of art forms to comfortably perform at this site?.

This Bachelor's thesis in Environmental Science studies the quality of an index of performance measurement of Swedish municipalities' sustainability governance offered by the environmental magazine Miljöaktuellt. Executed for six consecutive years, this evaluation is arguably the most comprehensive and widely spread local sustainability assessment in Sweden. Contextualizing this quantitative measurement tool in the paradigm of New Public Management, the research questions posed are: 'to what extent does the index employed by Miljöaktuellt correspond to the requirements of a set of quality criteria for sustainability assessment?' and 'is the index appropriate as a measure of, or a goal for, Swedish municipalities' internal sustainability efforts?' Through the perspective of evaluation theory, Miljöaktuellt's index is seen as a performance evaluation, thus categorizing this study as a meta-evaluation. Through a qualitative thematic approach, the index is analyzed using the 8 BellagioSTAMP-principles that were developed as tools for assessing quality of sustainability assessments as themes for the analysis.

This study examines the background and nature of the credit default index swaption (CDIS) and presentsrelevant methods for modelling credit risk. A CDIS is a credit derivative contract that gives the buyerright to enter into a credit default index swap (CDS index) contract at a given point in time. ACDS index, in turn, is a multi-name credit default swap (CDS). Within the eld of research, thisthesis identi es the CDIS pricing models presented by Jackson (2005), Rutkowski & Armstrong (2009)and Morini & Brigo (2011) as the most recognized and developed. These models are evaluated byreconstruction in a numerical software environment.
