Avsättningar i pappersmaskiner : Utbildning och förslag till processförbättringar

Deposits can be formed in the paper machine due to sticky materials from wood and recycled paper. These deposits get stuck on process equipment and cause the product quality to deteriorate and the efficiency of the paper machine is reduced. The purpose of this thesis is to increase the understanding about deposits among machine operators, and to suggest methods that can be used to reduce the amount of deposits formed in Bravikens paper machines.To fulfill the purpose of the thesis a pre-study, a literature review and interviews with machine operators and production staff, were carried out. These methods led to the planning and creation of an education about deposits for machine operators.The education about deposits for machine operators consisted of an interactive lecture to introduce the subject of deposits and a subsequent discussion. This approach was chosen to give the machine operators the opportunity to discuss their work situation on the paper machines related to their new knowledge about deposits.

Läs-och skrivinlärning : en kvalitativ undersökning av fyra pedagogers val av metod i läs- och skrivundervisning

Background: Language skills are of great importance for all work at school and for students' future life and activities. Therefore it is particularly important that preschool and school in every way possible should encourage and support ALL children's linguistic development. Many linguists points out that all learning takes place best in natural and meaningful contexts and around a meaningful content.Theory: The study is based on theories created by the renowned theorist Lev Vygotsky who illustrates what is important to encourage children's reading development. Vygotsky?s theories regarding the zone for the next development were reflected in the study.

Kunskap, motivation och stöd : En studie om kompetensutveckling inom statistisk analys av experimentella stöd

Testing and analysis of measurement data is a major part of the workday for development engineers within the section Fluid and Emission Treatment to assure the quality of products developed by Scania CV. The ineluctable variation and therefore uncertainty of results can be quantified and discussed with the use of statistical methods.The overall objective of this study is to examine how the competence of development engineers can be improved within the area of statistics. This has been done by relating the concept of competence with the use of statistical methods to analyse experimental data and by investigating which factors that influence the competence of the engineers. Observations of the daily operations, interviews and a focus group with development engineers and a workshop with management personnel, has been used as research methods in this study.The results show that the desired competence, from the perspective of the individual, consists of knowledge, motivation and support. It is important that none of these parts are neglected when the competence of engineers is to be strengthened.

Folkbiblioteket som en regional och lokal utvecklingsfaktor

This study aims mainly to investigate what kind of role the public library plays in the regional and local development. The aim is also to investigate how the public library can strengthen the role as a factor of regional and local development. To explore the subject, the study is focused on the Swedish region of Västra Götaland. Three officials along with two policy documents, are included in the study as representatives of the region. Four public library managers are also interviewed but as representatives of the local perspective.

Jämförelse av metoder för peroxidbestämningar i bränslen : A comparison of methods for determination of peroxide content in fuel

New energy resources that can replace petroleum diesel are needed and biodiesel may be an excellent substitute. During storage and use, biodiesel can oxidize and form peroxides, leading to degradation of the fuel. It is therefore important to determine the peroxide content of the fuel. In this thesis the triphenylphosphine method, which involves GC-MS analysis has been compared to the standard iodometric method which involves titration with sodium thiosulfate. Working standards were made to see how well the iodometric method worked and also in order to make a calibration curve in GC-MS.

Framtagning av samlingsrör för egen produktion

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Vetenskap, Teknologi och Ontologiska frågor

This essay is a study that takes interest in technical and technological change essential to philosophy of science. What is shown is the importance of an active attitude towards this change, by the articulation of the question: Does technical development lead to new ontological questions for science? - and by the answer that such questions do appear.It is clear that passive assumptions in this matter might prohibit science in the proceeding search for truth.By examples of ways in which technical development helps and challenges science, it is concluded that scrutiny of the relationship between technical development and ontological suppositions and hypotheses within science is well motivated..

Biomekanisk mätmetod och ergonomisk analys av träningsmaskiner

To get the maximal output of your exercise in gym machines, there are different factorsto be considered. For example the strength of the muscle varies dependent on the positionof the muscles. To get the best results of the exercise the load has to reduce and increaseat specific positions.This study was made in cooperation with Caretaker Scandinavia AB, a company forsales, marketing and development in health care. They are general agent for Nordic Gymwho works with manufacturing of equipment and machines for gym and fitness.The aim of this study was to generate a method of measurement to evaluate and controlthe biomechanics of Nordic Gym´s workout equipment. A protocol for an ergonomicanalysis on the equipment has also been elaborated.One of the methods to measure the biomechanics was to measure the torque through thewhole movement.

Att skriva sig till läsning- mer än bara ord : En kvalitativ studie på en mångkulturell skola, om läs- och skrivutveckling med datorer

The aim of the study is to see how teachers and students work in a multicultural school according to a method which teaches students to write before reading with the aid of computers. A further aim to investigate is how pupils with Swedish as a second language develop their linguistic skills using the method.To participate in modern society requires a lot from the individual. To function in a society that is constantly changing requires a good knowledge of the use of language in order to participate as a democratic citizen. It is therefore important that all students develop good linguistic knowledge regardless of their first language.The study is based on interviews with four teachers, operating in a multicultural school. Besides the interviews observations were made of the teachers and students in their daily work with computers.The results of the study showed that the method is language stimulating and develops the second language of the learners.

Kemin bakom framtidens avgasrening : En studie av ureasönderfall under kvävgasatmosfär

The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this Method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.

Inkluderande ?garskap i varierande demokratiska kontexter: En j?mf?rande fallstudie av svenskt utvecklingssamarbete med Rwanda och Tanzania

This thesis investigates how recipient countries' domestic type of democracy affects its inclusive ownership in international development cooperation. This is done by examining Swedish development cooperation with Rwanda and Tanzania during the period from 2010 to 2014, a time when ownership - a concept which emphasizes recipient countries' leadership over its own development - was a central part of the international development agenda. The two cases were selected through a most similar case design where the value of potential explanatory variables was similar, except for the recipient countries' types of democracy. Furthermore, the case study uses a comparative analysis to analyze strategies and reports done by SIDA and the Swedish Ministry of Foreign Affairs. Previous research focuses on the exclusion that national ownership can result in, in undemocratic national contexts. The main argument for this should be seen as the fact that ownership can not be representative if the power of the recipient's development agenda is limited to a decision-making elite.

Produktutvecklingsprocessen : En djupstudie i hur ekonomer, designers och designchef samarbetar i en produktutvecklingsprocess.

Competition in the market of interior design during the last several years has drastically increased. The consumers of today are very conscious about what the market can offer and therefore they have high demands on the products. It is not only the function of the product that matters but also the design that makes a difference. Companies are becoming more aware of this and as a result they have to find a way to set themselves apart in order to attract customers. This realization has led designers and economists to cooperate in a different way than before.

Leder icke användarcentrerad systemutveckling till låg användbarhet?

Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.
