Utveckling av mobilapplikation
The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones.In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment.To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA.
Analys och dimensionering av robusta kilspårsförband
This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

Kan fogen bli bättre Fogar i Industriellt byggande
Fogar i industriellt byggande tar allt mer plats och det diskuteras idag omfogar på annorlunda sätt i jmf. med innan när man inte visste vilken betydelse de hade i hela konstruktionen.Idag tar man hänsyn till personer som bor i själva huset och derashälsotillstånd, eftersom det är lika viktigt att vi mår bra i våra hus som att konstruktionen håller längre och det är allra viktigast att vi försöker undvika att använda miljöskadliga material som påverkar vår hälsa och när det gäller fogar att vi undviker PCB som är cancer framkallande. Mer om PCB, bifogar vi i Bilaga 1.Tekniken utvecklas fort och vi måste anpassa oss till dagens utveckling påvarje område, IT, bilindustri, byggindustri som strävar mot industriellt byggande men för att lyckas måste vi ta hänsyn till allt som ingår i byggkonstruktionen, bland annat fogar som vi valde som tema att fördjupa oss i vårt magisterarbete.Vi har undersökt fogar angående? var de förekommer? hur de uppför sig vid olika klimatförändringar? hur de anpassar sig till andra materials förändringar (krympningar)? vilken roll spelar anslutningar (betongelement) till rörelser som uppstår i fogar? vilka material används? skador som uppstår? var felet uppträder oftastGenom dessa undersökningar har vi försökt förklara problematiken somuppstår och åtgärder som är nödvändiga att göra.Slutligen försöker vi peka på, vad det är som man närmare skall studera, närdet gäller fogar för att undvika sprickbildningar och materialbrott i anslutande byggkomponenter. Vi vill också visa på vilket värde ?en god kommunikation? mellan inblandade parter har.Eftersom våra studier har visat behov av kunskapslyft i fogteknik, bifogar viett teknikkapitel om fogar i Bilaga2..
Att förhålla sig till den nära historien - och planera för den avlägsna framtiden :
This thesis concerns the term contemporary history and its role in landscape architecture. Today?s contemporary history is defined as the planning and architecture connected to the 60s and 70s, in Sweden carried out as a large scale planning project called ?Miljonprogrammet?, which set out to build one million new residences in ten years.
Initially, the term contemporary history and its complex of problem are examined.
To deepen the picture of today?s situation, a historical review has been made, starting in early 1900s ending in 2000s concerning how different planning and architectural influences has varied through the years.
Språkutvecklande arbetssätt i förskolan : language development approach in preschool
The purpose of this study was to investigate into the praxis based sociocultural tools that are utilized to enhance language development in early childhood education. Four pre-school teachers were involved in this study. Two were recruited from an independent pre-school "Maria Montessori", practicing the pedagogical philosophy developed by Maria Montessori. Two were from a public pre-school herein named "Kvasten", which has no official philosophy but where the teachers (like in many Swedish pre-schools) work in a general alignment with the principles of Reggio Emilia pedagogics. The theoretical fundament of the study lies in the general theories of language development and education of Jean Piaget and Lev Vygotskij, and the comparative element mainly concerns the variations in pedagogical praxis between the two pre-schools, and the way the teachers reason about language development.
Styrsystem : För en forskningsutrustning
The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.

Interna processer : Modell för ett effektivt returstålsflöde
The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.
Omkonstruktion av treaxlig plockrobot och dess plockverktyg
This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.
