Dragbrotschning av invändiga profiler

High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

Sunda energieffektiva väggkonstruktioner för morgondagens flerbostadshus

Detta examensarbete har utförts vid högskoleingenjörsprogrammet Byggteknik och design vid Kungliga Tekniska högskolan och i samarbete med Ramböll Sverige. Syftet med denna rapport är att undersöka och analysera dagens ytterväggskonstruktioner för framtidens energieffektiva flerbostadshus.  Ytterväggskonstruktionen som är en del i byggnadens klimatskal, har en viktig och betydelsefull funktion för att kunna klara av framtida byggnaders energikrav. För att en väggkonstruktion ska fungera finns det en rad andra påverkande faktorer som måste tas hänsyn till. Därför kommer examensarbetet att fokusera på ytterväggskonstruktioners byggfysikaliska egenskaper såsom lufttäthet, fukt, uppbyggnad och beständighet. För att kunna lösa uppgiften har vi varit i kontakt med åtta olika byggnadsentreprenörer i Stockholmsområdet och utfört studiebesök ute i produktionen. Det finns flera faktorer som styr valet av ytterväggskonstruktion för projektet och på grund av detta finns det en rad olika typer av ytterväggskonstruktioner som används i dagens byggande av flerbostadshus. I vår jämförelse mellan sex olika ytterväggskonstruktioner har vi analyserat byggfysikaliska egenskaper och produktionsmetoder utifrån samma grundparametrar.

This master thesis is one part of a project, called ?StabSim?, with the purpose to develop a simulation model for the align and stabilisation system in main battle tank 122. The origin of this project is that it should be possible to make control analysis without risking any hardware. Besides that it will be easy to change components in order to investigate the behaviour of the system. The report includes modelling of tower and weapon mechanics and also the modelling of the synchronous motors, which control these.

Skolans fysiska miljö och hur den påverkar elevernas skoldag : En studie från två skolor

This study aims to examine what students in two schools think of the physical environment in their school, and how this affect their studies. My main question I wanted to answer was:How does the students think that the physical environment affect their day in school?I also wanted to find out what the students think is important in the physical environment in their school. The study is based on interviews with students i two different schools. One secondary school, in which three eight-grade students were interviewed, and one high school in which two students were interviewed. The result of the interviews is that the students think that their work in school is affected by the physical environment. The most important things is to feel safe in school and to have the possibilities to do studies without limitations in the environment, for example room to do their own studies, and a flexibility and variation in the environment.

Rum i förändring - en studie av Stapelbäddsparken sedd ur ett genusperspektiv :

By doing a study of Stapelbäddsparken from a gender perspective I have been investigating and analysing physical planning and landscape architectural design. My intention with this thesis is to reflect on what a gender perspective in physical planning means and what kind of consequences and effects it could have on physical planning and outdoor design. Gender is something that is created, moulded and transformed by social and cultural processes. And it also includes a dimension of power concerning the knowledge of the relationships between women and men where the standard in today?s society is still men?s interests. To implement gender in my analysis of the park I have been observing how the park is used and who is using it. I have also been investigating who?s needs and wishes that has been provided for in planning and design.

?? det är ju så jäkla frustrerande? - en kvalitativ undersökning av fysiskt aktiva individers upplevelser av socialt stöd i samband med träningsuppehåll efter en skada.

The purpose of this paper is to contribute to better understanding of the importance of social support for physically active individuals' experiences of training residence following an injury.The physical activity's impact on public health is well known. Increased physical activity also increases the risk of suffering an injury related to physical activity. The importance of social support for those individuals who suffer an injury related to physical activity is where increased knowledge is needed.Four interviews to were conducted using a thematic interview guide with the following themes: The experience of the training break, two sides of social support, several ways of dealing with the experience, the design of the support, Varied support providers relationship changes. The most important property of the individual who gave support was an experience similar to that of the injured individuals underwent. That, combined with the close relationship with the individual who gave support was seen as crucial to the experience of the social support role for the injured individual.The Conclusion was that social support is important for the experience of a break from exercise due to an injury related to physical activity..

Inneluftsventileradekryprumsgrunder : en utvärdering av två tillverkare

This Diploma work investigates internal air ventilated crawl-space in respect to construction and damp. The Diploma work assumes from a general description of crawl-space and general dump problems in ground construction. An internal air ventilated crawl-space is a construction where you take the ventilation air from the building and bring it down to the crawl-space and lets the air circulate before it passes through a retaining aggregate on the way out from the crawl-space. In this matter you get a worm space under the building and a lot less dump problems in form of · Ground damp · Build damp The ground dump reduces through draining around the building, different layer of gravel between the ground and the building and ventilation of the crawl- space. The build dump reduces through ventilation of the crawl-space as fast as possible.

Rörelshinder och ämnet idrott och hälsa : en kvalitativ studie om hur elever med rörelsehinder upplever ämnet idrott och hälsa

Drawing on data from one-to-one semi-structured interviews with six students in the age of 11-14 years, this study focused on how students with disability cope with their impairments and physical activity in school. The interviewees? background displays a wide range of sport related activities and besides school the interviewees seem to be engaged in different sports associations on their leisure time.

Nyttjande av ofrörbrukat byggmaterial : En rapport åt Peab Jönköping

This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away.When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material.

The objective wasto obtain a basis for recommendations on how window properties can be optimizedfor different types of buildings and orientations.

Löpmagsförskjutning hos mjölkkor : en besättningsutredning för att identifiera riskfaktorer för metaboliska störningar

The purpose of this study was to find possible explanations to why the studied herd had an increased incidence of abomasal displacements. The incidence of abomasal displacement in the herd was three times higher than the incidence of an average Swedish herd. The cows in this study were fed a total mixed ration. The different parameters studied were: energy content in food, nutritional content in food, body condition scoring, concomitant other diseases, and blood parameters of glucose, fructosamine, cholesterol, insulin, betahydroxybutyrat and free fatty acids. The author?s suggestions to decrease the problems are to decrease the energy content in the TMR to lower the cows? body condition scores in the dry period and changing the content in the TMR to increase the amount of NDF and adding structure in the form of chopped straw.
