Konstruktion av en mobil robot som kan röra sig i okända rum

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.

Bibliometrin och humaniora: En bibliometrisk analys av litteraturvetenskapen

The aim of this Master's thesis is to study whether bibliometrics can serve as a method to analyse the humanities.To investigate this a literature study was conducted that examined previous studies concerning bibliometrics and the humanities. Furthermore a bibliometric analysis of comparative literature was carried out. These research findings were then further examined through the perspective of theories on intellectual and social organization of the scienceThe bibliometrical study includes 38 literature journals (11 855 articles in total) which were downloaded from ISI's Web of Science. The material was analysed by using co-citation analysis and co-word analysis. The results of the study are presented in five co-citation maps.

Energieffektivisering av färskvattensystemet på Skärblacka pappersbruk

The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.

Lagring av kyla med horisontella markvärmeväxlare för kylning av koncepthus i Mellanöstern

Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.

Vad innebär övergången till Scrum? : En studie som undersöker hur Scrum påverkar systemutvecklingsarbetet i globala organisationer

Currently many organizations are transitioning from the traditional approach to the agile approach regarding systems development methods. It is evident that research has mainly focused on smaller organizations transitioning, whilst less focus has been given t0 larger organizations. We find this interesting and the purpose of this study is to gain a deeper and broader knowledge concerning the following research question: How is system development work affected by a change from traditional system development methods to Scrum in large global organizations. We also investigate how Scrum can be adapted to complex projects with an internal client. The study is based on a case study, which takes a qualitative approach with semi-structured interviews for information gathering and was conducted on a major Swedish telecom company.

36 nyanser av torsk : en osteologisk analys av fiskben från Hemmor i Dalbo i När sn på Gotland

The purpose of this paper was to analyze fishbones from the Pitted Ware Culture settlement named Hemmor. in Dalbo, När parish on Gotland. The fishbones are unburnt and derive from one specific culture layer (c:6) in trench one VI:7, and radiocarbon dated to 2600-2300 BC cal.In this paper I wanted to answer these following questions:1. What kind of fish species did they eat in Hemmor?2.

Evaluation of preanalytic methods in order to shorten the processing time before identification of fungal microorganisms by the MALDI-TOF MS

Identification of fungi is based on macroscopic observations of morphology and microscopic characteristics. These conventional methods are time-consuming and requires expert knowledge. For the past years Matrix-assisted laser desorption ionization-time of flight mass spectrometry has been used for routine bacterial identification in clinical laboratories but not yet in the same extension for fungi. In this study three preanalytic preparation methods for fungi were evaluated in order to shorten the processing time in routine laboratory performance.Clinically relevant strains (n=18) of molds and dermatophytes were cultivated on agar plates and prepared according to the different preparation methods for protein extraction. Each strain was analyzed in quadruplicate by the MALDI Biotyper and the database Filamentous Fungi Library 1.0.The results showed that the genus and species identification rates of the least time-consuming direct extraction method were 33% and 11% respectively.

?Man ska använda böcker som kan vara intressanta för killar? En analys av synsätt på läsning, läsfrämjande metoder och genus i projekt riktade mot pojkar.

The purpose of this thesis is to examine projects for readingpromotion, aimed at boys, between 8 and 16 years of age. Therelations between librarians approaches to reading and methodsfor reading promotion are analysed with a gender perspective.The study is based on qualitative methods. Librarians involved infour reading projects have been interviewed. In the analysis, ourempirical material is related to theories of approaches to reading.Results have also been compared with earlier studies regardingboys reading, reading promotion, gender and male stereotypes.We find that an emancipatory approach towards reading is themost common. The librarians´ views showed that discussion,development, reading for pleasure and focus on the content of thebook were central to the methods used in the projects.

Studie- och yrkesvägledning inom Sfi : En balansgång mellan utbildning, arbetsmarknad och individ

Syftet med studien är att beskriva och analysera studie- ochyrkesvägledares funktion i samband med elevers övergång från Sfi till andrastudier och arbete. Vidare sätts deras arbete i relation till uppdraget för Sfioch vägledning. Studien är avgränsad så till vida att den endast utgår frånstudie- och yrkesvägledares egen uppfattning om sin funktion och sitt arbete.Studien är kvalitativ, metoden är semistrukturerade intervjuer och urvalet bestårav tio informanter, samtliga utbildade studie- och yrkesvägledare som äranställda som det inom Sfi. Resultatet är att vägledare arbetar med informationoch vägledning individuellt och i grupp. Det finns stora skillnader i resurseroch organisationsstruktur mellan olika verksamheter vilket gör att arbetetuppvisar skillnader i omfattning och inriktning.

Axellagring till Klasserare

GE Healthcare wants to investigate whether additive manufacturing would be an alternative method in their workshops in the Umea? plant. Additive manufacturing is called 3D printing in everyday language and manufactures details by building them up layer by layer in an automated machine. The purpose of this work is therefore to investigate how mature additive manufacturing methods are and how they could be used at GE.The work has been divided into three parts. The first section investigates how additive manufacturing would work in the production workshop at GE.
