Folkbibliotekets nya roll i det digitala bibliotekets epok: : om e-böcker, Internetbaserade ljud- och talböcker och förbättrad tillgänglighet till folkbiblioteken i Stockholms län
The digital era has led to technical advances that have transformed the role of the public library from being a place that is used only through physical visits and material, into also being a virtual space that can be accessed by users from outside the library through Internet-based access to e-media such as e-books and streamed or downloadable audiobooks.The aim of this study is to examine how the role of public libraries in Stockholm County has changed in the process of developing into digital libraries: how this has affected their organisation, work methods and strate- gies, as well as their accessibility. The theoretical framework of the study draws on Michael K. Bucklands theory of information accessibility, which is based on six factors of access that are determined by different types of barriers. The methodology is based on a combination of quantitative and qualitative methods. Primary data was gathered through an empirical survey, which consisted of a structured questionnaire distributed to most of the public libraries in Stockholm County and semi-structured interviews with selected librarians and experts for further in-depth understanding.
Elevers koncentrationsförmåga under matematiklektioner på förmiddagar och eftermiddagar
This project has aim to examine how students experience their concentration ability during mathematics lessons in the mornings and afternoons, and how students? learning can be in-fluenced by the concentration ability during mathematics lesson in the morning and after-noons respectively? Which role do the methods of learning play in mathematic depending on which time it is carried out during mornings or afternoons with regard to student concentra-tion ability? In order to find out those issues, I used two methods; (interview and observa-tion).Interview with 4 students and 3 teachers and observations of 4 mathematics lessons based on a qualitative method. In order to measure students' concentration ability during ma-thematics education on various times, I distributed questions to 23 students and repeated it during each lesson that I have observed from a quantitative approach in two classes in a sec-ondary school. In the literature I discuss the definition of concentration, and factors affecting the concentration negatively and positively. What is the relationship between concentration, learning and type of activity and how individuals can improve their learning and attention? In addition I studied two earlier studies on the concentration.
Två metoder av finutsättning och dess noggrannheter
This report describes a study of two different methods to achive the best possible result in setting out apartment details. These two methods are the setting out of details with a measuring tape from baselines and the setting out procedure with an instrument (totalstation).Through our knowledge in surveying and mapping technology and help from a carpenter, this investigation has been implemented. The setting out using a tape has been performed by letting the carpenter to set out windows, bathroom and water- and drain-details from baselines and drawing. The setting out using a surveying instrument was carried out by means of a Trimble Total Station. These two methods have been compared in order to detect and show the difference that occurs.The report shows the investigation background story from the practice of Swedish Mätcenter in Karlstad.A result of differences in accuracy and time is described in the report, as well as their theoretical consequences.
Tillståndsskattning i robotmodell med accelerometrar
The purpose of this report is to evaluate different methods for identifying states in robot models. Both linear and non-linear filters exist among these methods and are compared to each other. Advantages, disadvantages and problems that can occur during tuning and running are presented. Additional measurements from accelerometers are added and their use with above mentioned methods for state estimation is evaluated. The evaluation of methods in this report is mainly based on simulations in Matlab, even though some experiments have been performed on laboratory equipment.The conclusion indicates that simple non-linear models with few states can be more accurately estimated with a Kalman filter than with an extended Kalman filter, as long as only linear measurements are used.
Jämförelse av olika metoder att generera Bernoullifördelade slumptal givet deras summa
In this master?s thesis the problem of simulating conditional Bernoulli distributed stochastic variables, given the sum, is considered. Three simulation methods are considered, namely the acceptance/rejection technique, Bondesson?s method and the Markov chain Monte Carlo method.To compare the three methods the bias and the standard deviations of the simulated variables are evaluated. The results of the simulation study shows that the Markov chain Monte Carlo method is not the best method for this type of simulation.

Verktyg för mätning av tjänstekvalitet på bredbandsnät
Operators and Internet service providers invest in broadband to be able to deliver new services that require higher data transmission rate. A way to make this possible is to use ADSL, Asymmetric Digital Subscriber Line, as the access technology. To be able to handle this technology, the service providers should do a pre-qualification. Methods and tools are needed to analyze the local copper lines and decide if these qualify for ADSL with respect to service availability and possible bandwidth through the lines. This report brings up some methods for pre-qualification of ADSL, the important quality parameters and how to gather them from the available services today.
Binär matchning av bilder med hjälp av vektorer från deneuklidiska avståndstransformen
This thesis shows the result from investigations of methods that use distance vectors when matching pictures. The distance vectors are available in a distance map made by the Euclidean Distance Transform. The investigated methods use the two characteristic features of the distance vector when matching pictures, length and direction. The length of the vector is used to calculate a value of how good a match is and the direction of the vector is used to predict a transformation to get a better match. The results shows that the number of calculation steps that are used during a search can be reduced compared to matching methods that only uses the distance during the matching..

ComAlong targets parents of pre-schoolchildren with extensive communication difficulties and aims to give parentsknowledge about different aspects of communication, communication developmentand AAC. Both qualitative and Quantitative methods were used. Individualinterviews and pair-interviews with totally nine persons were performed and 54course questionnaires filled in by parents were evaluated.
Validation of realtime-PCR of Fusarium avenaceum for detection in wheat
Mould is a common contamination in cereals. The growth of mould can stimulate mycotoxins production andsome of which at critical concentrations cause health problems in humans and animals. Fusarium is one of thefungus species that has been found in crops and can cause major problems for farmers such as reduced harvestand economic losses. A group of Fusarium species, Fusarium avenaceum, Fusarium poae and Fusariumtricinctum express a mycotoxin, enniatin. The limited information available today about enniatin-forming fungiis that they grow out on fields of wheat in colder climates.
Kundrelationer och kundlönsamhet: En fallstudie av ett modeföretag
This thesis studies the customer relationships and customer accounting methods used by a Swedish fashion company. The aim is to test the empirical applicability of the relationship based framework developed by Lind and Strömsten and to explain potential differences between empirical observations and theory. The framework is based on the categorization of four customer relationship groups and the appropriate customer accounting methods to be used for each relationship. The fashion company, that recently assessed the profitability of its customer base in an aim to implement a new customer strategy, is the object of the qualitative case study. The case study reveals that all customer relationships are to be found at Whyred, except the connective customer relationship.
Eleven i fokus : En studie över gymnasieelevers läsning
The aim of this study is to find out what education in literature is like from a student perspective; what kind of literature the students read and how well they understand literature, and the methods and didactics used during the literature lessons. The questions at issue are:1) What kind of literature do the students read?2) How well do the students understand literary texts?3) What do the students think about their literature education?To be able to answer the questions, both quantitative and qualitative methods have been used in the study. The inquiry was accomplished on 29 students, 17 boys and 12 girls in the upper secondary school. The result showed, despite the limited amount of students, interesting facts.
Barns sociala liv i hem och skola : Ur föräldrars och lärares perspektiv, relaterat till stressbelastande faktorer.
Den här studien handlar om barns sociala liv i hem och skola relaterat till faktorer som kan vara stressbelastande. Syftet med studien var att undersöka och belysa lärares reflektioner kring barns sociala liv i hem och skola, attityder och språkbruk i grundskolans tidiga år idag och för tio- femton år sedan. Syftet var också att undersöka och belysa barns aktiviteter efter skoldagens slut ur ett föräldraperspektiv. Syftet avgränsades till årskurs 2 i grundskolan. Metoden jag använt mig av har varit kvalitativa interjuver med tre lärare, samt kvantitativa enkäter till föräldrar till barn i två av de klasser där jag intervjuat lärarna.
Total organic carbon (TOC) and chemical oxygen demand (COD) - Monitoring of organic pollutants in wastewater
Total organic carbon (TOC) and chemical oxygen demand (COD) are two methods used for measuring organic pollutants in wastewater. Both methods are widely used but the COD method results in production of hazardous wastes, including mercury.The purpose of this study was to validate the method TOC that will replace COD and find a factor to convert TOC to COD. In this study 26 samples were analyzed from four sewage treatment plant in the municipality of Enköping.The results show that the COD method could be replaced by the TOC method.The factor for COD/TOC was between 3.1 - 3.3. Both methods will be used in parallel until 2013 when it will be forbidden to use the COD analysis..
Hur man genom kreativt arbetssätt kan gynna barn med läs- och skrivsvårigheter.
Abstract People who have problems with the written language will face serious difficulties in todays society. Our social structur is based on the criterium that every individual has to be able to read and write, and for this reason it is important that pupils with learning difficulties receive help. The purpose of my investigation is to examine how children with reading- and writing difficulties can benefit throught creative methods. Children with reading- and writing difficulties are in need of these creative methods that exist today. Amongst all of our public healht issues, dyslexia is one of the biggest problem we have today and children are therefor in need of these creative methods. Through qualitative interviews with two educationalists there has been established thad the creative way of working benefits children in many ways if it is preformed correctly.
