What works? : Grundläggande komponenter för ett positivt behandlingsutfall på institution med särskilt fokus på Kognitiv beteendeterapi (KBT) och dess tillämpning.

In Sweden there are many kinds of effort given youths with behavioral problems, one is institutional care. International research display a varying kind of results from this type of treatment. The aim of this study is to examine and illustrate which central components that results in positive treatment, but also starighten important components in KBT. On the basis of research results, important components for positive treatment have been illustrated as; the therapeutic relationship, the integrity of treatment, prosocial-contacts, positive climate in treatment, the continual of treatment, how to bring treatment to an end, the responsivity principle-the principle of need-the risk principle, learning and KBT.  Research also aims to investigate whether these components could be identified in the daily work of youth treatment on institution. This through a qualitative approach including six interviews held with staff working in treatment facilities.

Elever och självreglerat lärande. : En studie om grundskoleelevers uppfattning om inlärningsstrategier.

Scientists and educational psychologists research have seen on self-regulated learning as learningconstruction. Every scientists have developed their own terms and concepts in the events of explaining how self-regulation affects students learning-process. Keyprocesses in previous studies is the importance of the active choice, to be goal-oriented,and awareness is what students need to self-regulate their own learning. The purpose of this study is to examine how students use different educational learning strategies based on the principles for self-regulated learning (SRL). From the process of the previous research, different concepts and terms have been divided into three key concepts titled:Active choices and actions, Goal-orientation and goal setting, as well as consciousness and self-awareness.

Möjligheter och hinder för att utöka omfattningen av RoHS-direktivet

The RoHS Directive was introduced in order to restrict hazardous substances in Electrical and Electronic Equipment, EEE. It currently restricts the use of six hazardous substances/compounds; cadmium, lead, mercury, hexavalent chromium, PBB, and PBDE. The RoHS Directive currently includes category 1-7 and 10 in the categories of EEE listed in Annex 1A to the WEEE-Directive (Waste of EEE). The aim with the report is to investigate and elucidate prospects and obstacles to increase the scope of RoHS. This report mainly considers the inclusion of product categories 8 (Medical Devices) and 9 (Monitoring and Control Instruments).

Magiska ögonblick och förlorade möjligheter : En studie i möjligheterna att lära med utgångspunkt i elevernas förkunskaper, svårigheter med lärandeobjektet och variationen i det erbjudna lärandet.

This study is based on an interest in trying to understand what is needed to ensure that students actually learn in a learning object, in this study equations. Algebra is an area of mathematics in several studies proved to be a stumbling block for many students. Using letters in mathematis is difficult for most students according to research reports and it is also consistent with my own experince as a teacher. The purpose of this study was to seek answers to what in the lesson content and also during the interview that allowed the students to learn more about the learning object. Based on students' prior knowledge and the difficulties students might have with the learning object and the offer of learning, I try to get an answer to what might have contribut the students to developed knowledge of the learning object.

Detektering av sprickor i vägytor med hjälp av Datorseende

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

Processorienterad arkivredovisning : Ny arkivredovisningsmodell tilla?mpad i fem svenska la?rosa?ten

The investigation analyzed the implementation and application of the Swedish National Archives' new Process-Oriented Archives Description Model to activities of the hierarchical, function-oriented and decentralized university organizations.The basic reason why a new archive description has evolved is because documents are becoming more and more digital. It requires a new interpretation of how evidence is secured for their reliability and authenticity, and a new way of looking at provenance, for the purpose of describing and searching electronic documents. The new archive description model's logical structure is based on business processes.The relationship between the new archive description and a function-oriented organization's activities can be seen from the different outlooks of processes between archive activities and activities of the organization. It is also reflected in the modification that all universities have made ??of the new archive description model to be more flexible and pragmatic to fit a function-oriented organization.The relationship between provenance and process-oriented archive description is mainly the link between documents and business processes that produce them.

Konstruktion av demonteringsrigg : För gängade hydraulikcylindrar.

Dione kullager AB is a company in Uppsala, which sell industrialmachinecomponents, transmissionsolutions and provides repair serviceof hydraulic components.When a hydraulic cylinder is about tobe repaired it needs to bedisassembled. Because hydrauliccylinders usually work in dirtyenvironments and are heavilyworn some types of cylinders arealmost impossible to disassemble.Today the disassemble is made by hand,which means extra work for themechanics. In order to facilitate thedismantling of this type of cylindersa machine is to be developed for thispurpose and this is where this thesisbegins.The thesis has been organized in threephases: Literature study in whichfacts and theories are acquired.Concept generation in which differentconcepts, calculations, and solutionswere identified and selected. Thedesign phase where all the differentconcepts of components were assembledand simulated in SolidWorks. Similarstructures have also been studied inorder to identify necessary functions.The thesis resulted in a structurewhich is believed to meet therequirements.

Balkanisering och klassifikation : En komparativ studie av klassifikationen av forna Jugoslavien, beträffande språk, geografi och historia, i DDC och SAB

This master's thesis examines the possibilities of correction and change in a classification scheme, with regard to the changes that occur in the world the classification system intends to describe.Applying a comparative method and classification theory, the classification of the example of the former Yugoslavia (1918-1941, 1945-1991), its republics and successor states, and the languages, formerly known as Serbo-Croatian are examined through a comparison of the main classes and divisions of language, geography, and history, in Dewey Decimal Classification (DDC), and Klassifikationssystem för svenska bibliotek [Classification for Swedish Libraries] (SAB). Eight editions of DDC, from 1876 to 2014, are compared to seven editions of SAB, from 1921 to 2013. The editions have been selected in order to show the changes prior to, and following, the First World War, changes after the Second World War, and changes following the collapse of Yugoslavia in 1991.The examination shows that both systems have updated their editions according to the changes in former Yugoslavia over the years. DDC has well constructed facet schedules, especially Table 2 concerning geography, but fails, in some cases, to construct a logic and hierarchical structure for the republics and languages of Yugoslavia, partly due to the fixed classes and divisions that survive from the very first edition of DDC from 1876, but also as a result of the decimal notation, and its limitations, itself.SAB seeks to construct a hierarchically logic and equal scheme for the languages, areas, and states of the former Yugoslavia. Although the facets for geography and chronology aren't as developed as the ones in DDC, the overall result is that of a logically consistent and hierarchically clear classification, with short notation codes, thanks to the alphabetic mixed notation, which allows more subdivisions than the numerals and the pure notation of DDC.This study is a two years master's thesis in Archive, Library and Museum studies..

Leken som ett verktyg för lärandet

The present study deals with the importance of play for children's learning in preschool. The purpose is to investigate the importance of play for children's learning in preschool from a pedagogue?s perspective. The study is based on two issues: How does the pedagogue´s who were interviewed reason about the impact the play has on children's development? How does the pedagogue´s approach to make play a learning situation? The empirical data is based on semi-structured interviews with four preschool pedagogue´s.

SAB-SYSTEMETS AVDELNING Y : Dåtid, nutid, framtid

This Master's thesis concerns the classification of compact discs according to the Swedish classification system, SAB. The purpose of this thesis is to critically study and discuss category Y of the SAB-system and its application in Swedish public libraries. The classification system has undergone great changes from the first edition in 1921 until today. In 1921 there were no musical recordings in Swedish libraries, today they are responsible for a large part of the loans. We discuss how the system's category Y has corresponded with the musical development.

Skolbibliotekarien : Image Profil Identitet

International research has shown that through the involvement of the school library and the school librarian in the daily school work with the pupils, the pupil´s learning can be increased and reading comprehensions significantly improved.One purpose of this master`s thesis is to study the school librarian as a brand, representing the school library as well as the school librarian and whether there is a correlation between different comprehensions of the professional role of the school librarian. This is done by examining whether there is a difference between a specific librarian´s own perception of their professional role, compared to the image of the school librarian among teachers and principals working in the same school district and by comparing the profile the school librarian expresses with the image that is conveyed through communications via webpage, written and oral information given on services and competences provided by the school librarian and work carried out by her.A difference of comprehension of the school librarian´s competence and work, could be part of an explanation as to why the correlation between the involvement of school librarians in the school work and the improved learning achievements of the pupils has not resulted in the expected measures, regardless of the investments in school librarians and school libraries. The school librarians´ school identity could be difficult to establish. Whether or not the profiles and images of the professional role are consistent with each other is a much more manageable purpose which could go a long way of explaining the circumstances of the school libraries.That is the reason why we have examined whether the comprehension the school librarians have of themselves corresponds with the idea/ conception/ image conveyed to their surroundings, and with the idea/conception/image encompassed by people in their immediate surroundings..

Evenemang : Great event of Karlstad & Mariebergsskogen

In my study I have chosen to examine the mathematics in children's free play and everyday situations, with focus on sorting and classification. The purpose of the study was to see how children express their mathematical knowledge. I have chosen to use a qualitative method in my examination, here I did observations in a children's group where the children were between three and six years old. I also did interviews with the teacher's on the department to see how they relate to the mathematics and how they formulate the department to achieve as good a learning environment as possible.The result shows that the teacher's approach is incredible important to the children's learning ability and that they are always present to challenge and discuss together with the children. The observation indicates that children use mathematics all the time in their everyday situations and that it is the interaction between individuals and environment that affects children's development. .

Varför väljer elever att söka maskinprogrammet?

Abstract The main aim for this research is to come to an understanding for why young people choose to apply for the machine program when the time comes for the students to make their choice of upper secondary school program. The second aim for this research is to try and come to an understanding on how to make the machine program more interesting for future students to apply to.  The method of this research is quality method with the usage of interviews. With a total of six students in the first grade going on a school in the middle part of the country I tried to get answers to my questions. There are many things that affect students when they are facing what gymnasium program to choose and a very common answer by students in this study is that friends and work after school are some of the reasons for why students choose, for example, the machine program. The study also shows that parents has less influence of the students choice of gymnasium program and in fact, all students in this study made the choice to pick the machine program as their gymnasium program, but not always the machine program as their first choice. With the comparison of similar studies with my study the results are often in line with what other scientist have come up with.

Automatisering av flexibel fixtur

This thesis was conducted at Linköping University and SAAB Aerostructures, Linköping, and focuses on the automation of flexible fixturing in machining applications. At Linköping University a project called "Koofix" is conducted with support from Strategiska stiftelsen and several manufacturing industries including SAAB Aerostructures. The purpose of this project is to develop a more cost-effective, flexible, technique for fixation of workpieces during processing and assembly.Fixtures are an important part during the machining process, especially if you process the parts with high accuracy. Today a large number of fixtures are used at SAAB and they would prefer to reduce the number of fixtures by using flexible fixtures instead. SAAB uses one fixture for each article and this result in a high fixture cost and it also takes time to design and construct a new fixture.There are several advantages with using a flexible fixture such as that you can process workpieces with different length, height and thickness in the same fixture.
