Methods for Locating Distinct Features in Fingerprint Images
With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. By using yourself to verify your identity such risks as lost keys and misplaced passwords are removed and by virtue of this, convenience is also increased. The most mature and well-developed biometric technique is fingerprint recognition. Fingerprints are unique for each individual and they do not change over time, which is very desirable in this application.

Fördjupad miljöriskbedömning av förorenade markekologiska system. : Integrering av kemisk, toxikologisk och ekologisk information.
AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).
Användbarhetsutvärdering av det lätta sandwichmaterialet Hybrix för bilkarossapplikationer
This M.Sc. thesis is a material application evaluation commissioned by the advanced body engineering department at SAAB Automobile AB. The purpose of the thesis is to evaluate implementation of the innovative sandwich design material Hybrix into an automobile body. Today the most commonly material used in the body is galvanized steel sheets and by shifting material to Hybrix several problematic issues have to be dealt with. Hybrix is an innovative sandwich sheet that inherits thin stainless steel face sheets and a stainless steel fibrous core.
Flockning och förtjockning i High-Rate-förtjockare ? en jämförelse med konventionell förtjockarteknik och lamellsedimentering.
In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

Vi har använt oss bl.a. av Pauline Gibbons litteratur ?Stärk språket, stärk lärandet? och ?Lyft språket, lyft tänkandet.
KORTSIKTIG PRODUKTIONSPLANERING I MINDRE FJÄRRVÄRMESYSTEM : En studie vid Strängnäs Energi AB
District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Torkning av vallfrö :
In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the
fields, this is primarily used as feed for livestock. To get a good seed, you need to
handle the crop carefully from planting to delivery. The part that I have been
interested in, is how to dry the harvested seed with out destroying the growth in the
small seed. This is very easily done if you aren?t careful during the drying period.
Faktorer av betydelse för styrkeutvecklingen i nedre extremitet vid kombinerade uthållighet- och styrketräningsprogram: En beskrivande litteraturöversikt
Vissa studier som undersökt kombinerad styrketräning och uthållighetsträningjämfört med styrketräning har funnit hämmad styrkeutveckling vid kombinerad träning. Forskning har därför riktats mot att undersöka hur hämmad effekt kan undvikas. Syftet med litteraturöversikten var att genom att granska vetenskaplig litteratur i området beskriva faktorer av betydelse för styrkeutvecklingen i nedre extremitet vid kombinerade uthållighetoch styrketräningsprogram. En beskrivande litteraturstudie gjordes på ämnet. En litteratursökning genomfördes mellan 6-24/9, 2014 i databaserna Scopus, Proquest, Pubmed, Cinahl, AMED, Web Of Sciense.
En skildring av hur tredje världen framställs inom ett urval av västerländsk barnlitteratur utifrån en postkolonial teori : En kvalitativ textanalys
In recent years, the characterization of the Third World and its inhabitants in West-originated children?s books has been subject to debate. Media attention around a selection of books has generated discussions on how this relates and aligns with Sweden?s national teaching curriculum. The objective of this study is to explore how a selection of authors, born in Western countries, have characterized and presented the Third World and its inhabitants in its literature.
Hur användbar är den implicita riskneutrala sannolikhetsfördelningen i turbulenta perioder? En studie av svenska val och folkomröstningar.
Denna kandidatuppsats fokuserar på den unika information som finns gömd i optionspriser. Med hjälp av marknads- och teoretiska priser på dessa kan den implicita riskneutrala sannolikhetsfördelningen geräknas, vilken antas vara den sannolikhetsfördelning som aktiepriser följer. Kännedom om denna fördelning torde alltså vara av stort intresse för marknadsaktörer. Uppsatsen ämnar utvärder hur pass användbar nämnda fördelning är i perioder som anses politiskt och ekonomiskt turbulenta, och främst syftas till att bedöma hur pass väl osäkerheten föregående vissa utvalda regeringval och folkomröstningar avspeglas io fördelningen. Den implicita riskneutrala sannolikhetsfördelningen karakteriseras förutom av varians även av de högre momenten skevhet och kurtosis.
3D-skrivarens intåg i immaterialrätten : - Om 3D-bilder, 49 § URL och vikten av lämpliga avtalslicenser
The current study aimed to test the public self-consciousness impact on creative performance. An experimental design was used in which 40 participants were randomly assigned to two groups, one of which was the experimental group and the other was the control group. A mirror was used in the experimental group to induce public self-consciousness among the participants while they performed creativity tests. A consequence test was used where the participant had to give suggestions for the given scenario "What would happen if everyone became blind?" which was then measured in the number of proposals (fluency).
Yrkeselevers svenskkunskaper 1977 och 2014 : En studie av två elevgruppers resultat på ett centralprov
The aim of this study is to investigate how the Swedish language proficiency of pupils in vocational programmes in 1977 was measured and assessed with the aid of a national achievement test, and to investigate whether vocational pupils today, in 2014, have similar language proficiency to that of pupils in the 1970s. The study also discusses how the design of the national achievement test from 1977 reflects the view of knowledge that prevailed in society and in the policy documents. The material for the study consists of a total of 75 national achievement tests, 40 of which were taken by pupils on a vocational programme in 1977 and 35 by pupils on a vocational programme in 2014. The national achievement test consists of two parts, the first of which focuses on isolated elements of language proficiency, while the second involves free text production. The material was analysed quantitatively in accordance with the correction material from 1977.
