Bättre utnyttjande av nya och befintliga förrådslokaler på SSAB Tunnplåt

The purpose of this assignment at SSAB Tunnplåt in Borlänge was mainly to investigate and describe the circumstances for the spare parts stored in storage facilities within the area of operation. Even new facilities which could serve as storage rooms and their opportunities for storing spare parts were an important part of the investigation. This because of the need for improved storing of spare parts. Furthermore, market offers where reviewed for storage of spare parts in more tailored designs. The work will culminate in proposals for improvement which is of importance for the development surrounding the storage and handling of spare parts. This is since the design and management of existing storage facilities is not perceived as satisfactory with regards to spare parts characteristics. Moreover, the amount of stock locations is too few in relation to the actual need. The approach used to achieve objectives of the work was an advanced mapping for collection of vital data. The mapping consisted of interviews with involved parties, both internal and external, for the most comprehensive picture of the problems as possible. In addition, a literature survey was conducted to identify possible options for the objectives of the work as well as a personal study of existing and new storage facilities. Furthermore, the market offers for improved conditions in storage rooms were examined. A clear picture of internal logistics and warehouse activities for spare parts at SSAB Tunnplåt has been obtained during this work. From this picture, it is concluded that work in and around storage facilities can be made more efficient. SSAB Tunnplåt should additionally make efforts in the storage facilities for better use of the available storage space. A number of proposals for improvement for each studied storage facility and spare parts management in general have been conducted. These proposals for improvement include presentations to improve the design of the studied storage facilities towards enabling more stock locations. The proposals also include additional equipment for handling spare parts, scrap handling, as well as expansions of the maintenance system which supports activities in the spare parts management.

Developing Optical Character Recoginition for Ethiopic Scripts

The Amharic language is the Official language of over 70 million people mainly in Ethiopia. An extensive literature survey and the government report reveal no single Amharic character recognition is found in the country. The Amharic script has 33 basic characters each with seven orders giving 310 distinct characters, including numbers and punctuation symbols. The characters are visually similar; there is a typeface, but no capitalization. Beside this there is no any standard font to use the language in the computer but they use different fonts developed by different stakeholders without keeping a standard on their own way and interest and this create a problem of incompatibility between different fonts and documents.This project is to investigate the reason why Amharic optical character recognition is not addressed by local and international researchers and developers and finally to develop Amharic optical character recognition uses the features and facilities of Microsoft windows Vista or 7 using Unicode standard.

Characterization of residential chimney conditions for flue gas flow measurements

A literature survey and a theoretical study were performed to characterize residential chimney conditions for flue gas flow measurements. The focus is on Pitot-static probes to give sufficient basis for the development and calibration of a velocity pressure averaging probe suitable for the continuous dynamic (i.e. non steady state) measurement of the low flow velocities present in residential chimneys. The flow conditions do not meet the requirements set in ISO 10780 and ISO 3966 for Pitot-static probe measurements, and the methods and their uncertainties are not valid. The flow velocities in residential chimneys from a heating boiler under normal operating condi-tions are shown to be so low that they in some conditions result in voiding the assumptions of non-viscous fluid justifying the use of the quadratic Bernoulli equation. A non-linear Reynolds number dependent calibration coefficient that is correcting for the viscous effects is needed to avoid significant measurement errors. The wide range of flow velocity during normal boiler operation also results in the flow type changing from laminar, across the laminar to turbulent transition region, to fully turbulent flow, resulting in significant changes of the velocity profile during dynamic measurements. In addition, the short duct lengths (and changes of flow direction and duct shape) used in practice are shown to result in that the measurements are done in the hydrodynamic entrance region where the flow velocity profiles most likely are neither symmetrical nor fully developed. A measurement method insensitive to velocity profile changes is thus needed, if the flow velocity profile cannot otherwise be determined or predicted with reasonable accuracy for the whole measurement range. Because of particulate matter and condensing fluids in the flue gas it is beneficial if the probe can be constructed so that it can easily be taken out for cleaning, and equipped with a locking mechanism to always ensure the same alignment in the duct without affecting the calibration. The literature implies that there may be a significant time lag in the measurements of low flow rates due to viscous effects in the internal impact pressure passages of Pitot probes, and the significance in the discussed application should be studied experimentally. The measured differential pressures from Pitot-static probes in residential chimney flows are so low that the calibration and given uncertainties of commercially available pressure transducers are not adequate. The pressure transducers should be calibrated specifically for the application, preferably in combination with the probe, and the significance of all different error sources should be investigated carefully. Care should be taken also with the temperature measurement, e.g. with averaging of several sensors, as significant temperature gradients may be present in flue gas ducts.

Unga vuxnas upplevelse av sjuksköterskans bemötande av psykisk ohälsa vid kontakt med hälso- och sjukvården - en litteraturöversikt

Bakgrund: Unga vuxna som sökte vård sökte oftast inte för den psykiska ohälsan utan istället för något somatiskt. Det är viktigt att få de yngre vuxna att söka sig till vården när behov uppstår och underlätta till en god förbindelse mellan sjukvården och de unga vuxna. Syfte: Syftet med denna studie var att beskriva unga vuxnas upplevelser av sjuksköterskans bemötande av psykisk ohälsa vid kontakt med hälso- och sjukvården. Metod: Studien genomfördes som en litteraturöversikt. Resultat: För de unga vuxna var det inte lätt att komma in i vården på rätt vårdnivå om personen inte kom i kontakt med en sjuksköterska som hade ett holistiskt synsätt. Vården för de unga med psykisk ohälsa bör vara tillgänglig och informationen om tillgängligheten behöver ständigt upprepas. Slutsats: Det är viktigt att sjuksköterskor har kunskap och erfarenhet av unga psykiska människor för att kunna hjälpa dem med den psykiska ohälsan när de söker vård. Relationen mellan patienten och sjuksköterskan är av stor vikt för den fortsatta kontakten med vården för den unge vuxna. Det är viktigt att de känner tillit och förtroende.

Students’ Perspectives on Extensive Literature : Using Literature to Enhance Communicative Competence and Cultural Understanding in the EFL-Classroom

The aim of this thesis is to investigate the use of literature within the Swedish Upper Secondary EFL-classroom from the students’ perspective. How do the students in the study relate to literature and its use to enhance and enable their communicative competence and cultural understanding? Also, how do their answers compare with their teacher’s and the adult perspectives and findings from previous international research? The empirical data obtained from the study has been analysed from the perspectives of sociocultural and motivational theory, and the findings show that the participating students believe literature to be a good didactic tool to apply in the EFL-classroom, both in order to enhance their communicative competence and their cultural understanding. The students prefer to have a sociocultural approach to their literature-learning, with group-discussions of various sizes. The key for the students in this respect is interesting, relevant and engaging subject-matter, as well as a positive and motivational teacher. The responses given by the students correlate with those given by their teacher as well as previous international research. The students regard literature as a way of gaining new perspectives, as well as experiencing language in use. Where they diverge somewhat from the international research is in regard to literature’s use for enhancing their competence to speak in class, and that some students seem to think that communication and cultural understanding are separable. Future studies within this field might include the conducting of a larger and more in-depth survey regarding the students’ ideas about literature, culture and communication. Why do so many of the student respondents neither agree nor disagree with the statement concerning communication and cultural understanding being inseparable? This can be an important issue to investigate in today’s global climate of cross-cultural and intercultural experiences, especially in view of the political climate of diverse attitudes towards refugees, immigrants and emigration

An Empirical Study on Teachers’ Choice of Extensive Literature in the Swedish Upper Secondary EFL Classroom

The importance of extensive literature reading in the English as a Foreign Language (EFL) context has been given increasing attention in recent research. Literature reading is also a required part of the national syllabi of the (EFL) courses offered to both adolescents and adults at Upper Secondary level in Sweden. This thesis aims to investigate the teachers’ process of making literature choices for extensive reading in upper secondary EFL courses in Sweden. Eight teachers of three different student groups took part in the study, representing adolescent university preparatory programs and vocational programs, as well as programs for adult students. Questionnaires were used and the data was analyzed for patterns revealing three main factors affecting teachers’ literature choice: language proficiency, reading experience and contextual factors. These three factors were fitted into the theoretical framework of psycholinguistic and sociolinguistic reading models, with the addition of a perspective of motivational research. The results of this survey underline the importance of extensive reading, according to teachers, and that motivation for literature choice can be primarily related to factors associated with psycholinguistic reading models. The survey also points to the need for further investigating of teachers’ own experiences of literature reading, searching for deeper motivational factors which influence teaching choices. Another future field of research is the choice of reading activities assigned together with the chosen literature, which probably also influence teachers’ choices in the Swedish EFL classroom.

English as a Second Language and Children’s literature : An empirical study on Swedish elementary school teachers’ methods and attitudes towards the use of children’s literature in the English classroom

Previous research has shown multiple benefits and challenges with the incorporation of children’s literature in the English as a Second language (ESL) classroom. In addition, the use of children’s literature in the lower elementary English classroom is recommended by the Swedish National Agency for Education. Consequently, the current study explores how teachers in Swedish elementary school teach ESL through children’s literature. This empirical study involves English teachers from seven schools in a small municipality in Sweden. The data has been collected through an Internet survey. The study also connects the results to previous international research, comparing Swedish and international research. The results suggest that even though there are many benefits of using children’s literature in the ESL classroom, the respondents seldom use these authentic texts, due to limited time and a narrow supply of literature, among other factors. However, despite these challenges, all of the teachers claim to use children’s literature by reading aloud in the classroom. Based on the results, further research exploring pupils’ thoughts in contrast to teachers would be beneficial. In addition, the majority of the participants expressed that they wanted more information on how to use children’s literature. Therefore, additional research relating to beneficial methods of teaching English through children’s literature, especially in Sweden, is recommended.
