An increasing number of companies are interested in this way of working. The following report is the result of a study on the ability to create value for customers in business development through the use of agile methods. We ask what the advantages and limitations of agile methods are in the creation of customer value. Grounded Theory and an initial literature review was used to answer this question.
Hur har det svenska handelsmönstret påverkats av ett medlemskap i EU?
Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.
Metodval i magisteruppsatser ? En studie av magisteruppsatser vid Bibliotekshögskolan i Borås
The aim of this meta-study is to present an overview of the methods used in Master theses written at The Swedish School of Library and Information Science at the University of Borås, where all Master theses from 1999, 2004, and 2009 has been studied. The aim includes examining if there is a connection between college (Swedish term: kollegium) belonging and methods used but also to examine and compare the qualitative and/or quantitative approaches to the methods. In the 252 Master theses studied, 353 different choices of method are recognized. After taking note of the methods, six categories are created in which the methods are placed. The categories are: Interview, IR-test, Observation, Studies of Text, Survey, and Other.
Styrsystem : För en forskningsutrustning
The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.
Vilka kompetenser räknas för nyanställning i bygg och industribranschen?
Studiens syfte är att ge fördjupad kunskap inom studie- och yrkesvägledningen gentemot kvinnor som kommer från länder utanför Europa och som har en akademisk utbildning med sig till Sverige. Studien utgår från att kvinnorna går på SFI. Undersökningen är utformad utefter både vägledarperspektiv och sökandeperspektiv. De centrala frågorna i studien belyser den konkreta vägledningen, svårigheter och möjligheter samt motivation och ambition. Den senare delen av studien berör frågan om cooling down, det vill säga om de sökande upplever att deras ambitioner blir dämpade eller modifierade.
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.
En utvärdering av två pearl growing-metoder i ISI Web of Science
The purpose of this thesis is to evaluate two pearl growing methods in ISI Web of Science. The methods tested are Find Related Records FRR, an automatic service that uses bibliographic coupling, and Author Keywords AK, where searches are performed using the two first keywords from this field. Both search methods were used on twenty initial documents and the first twenty hits were evaluated for relevance using a binary scale 0,1. The relevance criteria were based on specific information needs connected to every initial document. The measures used to evaluate the effectiveness of the search methods were Precision at DCV=10, P10, and Uninterpolated Average Precision AP.
Bankers identifieringsmetoder : Nu och i framtiden
Keywords: ID-method, internet, security, digitzing, bank Background: The digitizing of our society continues to grow and more parts of our lives is spent on the internet. The banks are one of the institutions that is at the forefront of this development since they established themselves on a early basis. The banks meeting points have since this establishment moved from the regular bank office out on the internet. A problem that has occurred during this transfer is the possibility to positive ID a customer in a virtual world. It is essential to offer the customer methods to identify themselves that are both safe and easy to use.

Boendepedagog: strävan från yrke till profession : En kvalitativ studie om implementeringen av boendepedagogik
The aim of the study was to look at a particular work group of housing supporters, whomhave implemented two special working methods in their work. The methods have been implemented by two of the housing supporters that also have special education in the methodsSOC (Sense of Coherence) and solution focused brief therapy. The study is based on anethnographic observation and analysis of documents that are used in the implementation. To analyse the information that was given at the observation and in the document I´ve used a theory which illustrates the significance of developing professions so their knowledge become legitimate. I´ve also used a theory that illustrates the importance of implementation and how it´s done at its best.
Spam : den nya tidens onlinegissel
This thesis takes on a broader perspective of the modern age phenomenon we call spam. One of the aims of this thesis is to present and to compare the variety of methods used in the day-to-day fight against spam, as far they have evolved today, but also to present and discuss some alternative methods for suggested future use. The properties of a common e-mail spam are analyzed to show how the components that make up the structure in an e-mail can be used to classify spam. Furthermore I explain the naïve Bayesian classification methods, the signature-based method, the commonly used rule-based method and the challenge and response method and discuss these. The widespread use of blacklists is also explained and a close new variant to blacklisting, Turntide is presented and discussed.

Läsinlärningsmetoder : En kvalitativ studie om pedagogers val av metod för läsinlärning
The purpose of this study is to investigate the reading methods that pedagogues, active in classes 1-3, use in the first stage of learning to read and how they consider their own choices of methods. In the theoretical background I sort out the basic differences between synthetic and analytic methods of acquiring the skills of reading. The analytic reading method means that the skills of reading starts with the complete text in order to later analyze the parts of the text. The synthetic method approach is based on a reading method where the parts are linked as a whole. The two methods are considered antipodes but can also be looked upon as complements in the current governing documents.
Undervisningsmetoder för elever med autism : En studie av pedagogers metoder med avsikt att utveckla lärandet för elever med autistiska syndrom
This essay talks about how teachers in schools are working with a particular focus on students with autistic syndrome. The aim is to investigate the methods used for these students, who develop their learning and achieve the goals of the school. The methods that were used in this study were two interviews in two different schools in central Sweden where teachers and professionals were interviewed. One part of the study was to compare both schools to see which methods they used and when they used them. My interest for autistic students started during my practice in a school.
