Utvärdering av infästningar i sandwichkonstruktioner för fordonsapplikationer
The automotive industry is increasingly studying lightweight solution in their designs, also rational production and low costs in materials and manufacturing methods are of great interest. This thesis consisted in the practical evaluation of anchors for sandwich panels. The object was to study loads of shearing and pull out of the plane. The experiments were carried out on panels made up of 1mm aluminium coatings and 50mm extruded polystyrene (XPS) at its core. As the fasteners used simple methods such as blind rivets, screw and glue.
"Man Kan Inte Klappa Med En Hand" : En intervjustudie om pedagogers uppfattningar av invandrarföräldrars delaktighet i förskola
The purpose of the study is to explore preschool teachers experiences of how immigrant parents become involved in the preschool activities and how their linguistic and cultural background appears in relation to participation.The survey was conducted through individual interviews with eight preschool teachers working in various multicultural preeschools.The results of this survey shows that the preschool teachers perceive that parents with different cultural and linguistic backgrounds are reluctant to participate in various forms of cooperation, such as parent meetings. Preschool teachers believe that the lack of parental participation depends on the parents linguistic and cultural backgrounds, such as different approaches to understand the pre-school educational activity or the view of parenting, and other things such as language difficulties.Another result reveals also a great lack of written methods, because teachers sometimes face difficult dilemmas. To seek itself the right approach in a current situation can be both difficult and time consuming, therefore, the preschool teachers wish that there were already complete methods for use..
Samband mellan självskattad fysisk aktivitetsnivå och aktivitetsregistrering via dagbok
Syfte: Studiens syfte var att undersöka samband mellan hur universitetsstudenter skattar sin fysiska aktivitetsnivå och hur de registrerar aktivitetsnivå med hjälp av dagbok samt att se om de kom upp i ACSM (American College of Sport Medicine) och WHO´s (World Health Organisation) rekommendationer.Metod: Studien hade en icke experimentell, deskriptiv och korrelerande design där 26 försökspersoner, två män och 24 kvinnor, rekryterades via anslag. De fick först svara på en enkät och därefter registrera sin aktivitet via en 7-dagars aktivitetsdagbok.Resultat: Studenterna ansåg inte att de hade en stillasittande livsstil och alla deltagare utom en ansåg sig komma upp till ACSM´s rekommendationer av fysisk aktivitet 30 minuter per dag av måttlig intensitet alla dagar i veckan. Trettiofem procent kom inte upp i WHO´s rekommendationer och av dessa överskattade 67% sin fysiska aktivitetsnivå. Sextiofem procent kom inte upp i ACSM´s rekommendationer och av dessa överskattade 94% sin aktivitetsnivå.Konklusion: Studenterna hade en låg fysisk aktivitetsnivå utifrån ACSM´s rekommendationer och majoriteten av de som inte levde upp till WHO och ACSM rekommendationer överskattade sin fysiska aktivitetsnivå. Det krävs dock mer omfattande studier för att dra några generella slutsatser då denna studie hade en skev könsfördelning och ett lågt antal deltagare.Keywords: Self-estimation, Perception, Activity diary, Physical Activity level, Overestimation. .
Elever som hänger med : en kvalitativ studie om skolsituationen för elever som enkelt klarar skolans uppnåendemål
The purpose of this research has been to find out whether and how teachers stimulate and motivate well achievers in the elementary school to reach a higher level. To gather information I visited two different schools within the same county in Stockholm and on each school I met and interviewed with two teachers. The answers received from these interviews are presented in this study as my results. I found that the teachers feel that students that do well in the classroom many times work as role models for the other students. Often these students require extra material as they usually finish their workload ahead of others.
Ledtidsreducering ur ett värdeflödes-perspektiv
This case study is performed within the production of Sherwin-Williams, Bellö. The purpose is to increase the understanding how a value stream can function more efficient, from a lead time perspective. With the analytical model that is build up on known theories, the purpose have been fulfilled. Mapping of value and non value time for four products thru their respectively process reveals wastes, which is, waiting, transport and movement, incorrect processing and set-up time that in it self create transport and movement. Thru identified wastes that causes loss in lead time suggestions of improvement has been proposed.
Konstruktion av formkropp pa JAS 39 E/F Gripen
The aim of this work is to develop new conceptual designs for the fairings that are situated between the fin and the rear fuselage on the new version of the JAS 39 Gripen aircraft, called the Gripen E/F. The designs presented should show a profit in the form of lower weight. To achieve weight loss, the possibilities of using other construction materials other than those which are available at Saab today were studied. Therefore, a material survey was carried out in which the market for modern construction materials was studied to get an idea of today?s level of technology.
Beräkningsmodul för ett förbättrat offertförfarande och minskad icke-värdeskapande tid
In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to handle it.The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data.
?Det är inte förrän man gör någonting av det som det har en betydelse och kan användas? : Lärares realiserande av kursplanens grammatikmål
This paper set out to investigate how teachers of Swedish in Sweden implement the grammar objectives of the curriculum in their teaching, through interviewing six teachers. It has been important to compare their methods to modern research of grammar teaching and teaching in general. They have been asked a series of questions to answer whether or not they use grammar terminology as mediating tools, if they intergrate dialogue among students in grammar teaching and to what extent the teachers? knowledge of and attitude towards grammar influence their teaching methods. The results show that grammar is used as mediating tools primarily when it comes to feedback on pupils? texts, though not to a great extent; dialogue between pupils is rare when it comes to grammar teaching; and the teachers? grammar knowledge and attitude affect the teaching methods, primarily in the sense that seeing value in grammar knowledge increases the teacher?s desire to develop new methods for grammar teaching..
