IKEA wants that the new product would make the opportunities better for people who don't have cars to carry their goods home easily on the bus, train or walk after their purchase.The report includes a suggestion for a new product that will fit into the existing FRAKTA -serial. The new development product will continue the same standard as the other products in the serial and it will also make it possible for customers to carry their goods home by public transportations..

In this study it was investigated if the adoption of a new routine for quality control could improve the precision of the dimension measurement obtained by harvesters. Data was collected from three different harvesters. First, a reference data set was collected before the new procedures had been incorporated, and then when the new methodology was implemented another data set was collected by the harvester operators, allowing the two data set to be compered. The results indicated that following the implementation of the new procedures, the reliability and the precision of the measurements has increased. All harvesters included in the study had improved regarding most of the controlled factors such as standard deviation, systematic difference and hit rate within ± 2 cm for length and ± 4 mm for diameter..

Försök sätta er in i att man får tillfälle att omvandla sitt sommarställe, där möjligheterna till nyttjande varit begränsade till sommarhalvåret, till ett fritidshus med boendemöjlighet året runt. Tänk att man får byta trånga, ogenomtänkta och halvfärdiga utrymmen till stora luftiga ytor med modern standard, hög komfort och smarta förvaringslösningar. Tänk er att ytorna mer än fördubblas och att du faktiskt kommer att kunna förvara en del saker i det nya huset som du tidigare behövt släpa fram och tillbaka mellan fast bostad och sommarhus.Det är vad sju familjer fått möjlighet till och som kommer att vara en del av det här arbetet..

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

In this diploma work the approach of determining the required amount of reinforcement in slabs exposed to pure tension is processed, on behalf of Ramböll Uppsala. It is a well-known problem in the industry that there are uncertainties in the determining of the amount of crack reinforcement, especially for structures exposed to pure tension. Cracking caused during the time of dehydration in concrete slabs is the most common defect according to statistics made by CBI[1], which provides numbers as high as 35 % of all the defects caused on slabs are generated by cracks. Comparisons between Sweden's former national standard BBK 04, Building Regulations for concrete structures due to restrained forces of shrinkage, and the current European standard Eurocode 2 are carried out through theoretical studies and concludes with several examples of calculations. Rigorous calculations of both standards, BBK 04 and Eurocode 2 with application of the national annex in Sweden and Denmark are performed.

Banverket är den myndighet som har ansvaret för järnvägstransportsystemet i Sverige och är enproducent av järnvägsinformation. En stor del av infrastrukturinformationen lagras i baninformationssystemetBIS och Banverket är förpliktad att tillhandahålla den. I nuläget är informationenåtkomlig på ett lätt sätt främst internt. Dessutom ställer dagens samhälle krav på att informationenska levereras enligt standard. Standardiseringsorgan har tagit fram standarder för geografiskinformation som svar på behovet att återanvända och samutnyttja geografiska data.Vårt examensarbete är genomfört på Banverket Verksamhetsstöds IT-avdelning och var inriktatpå att kartlägga standarder för geografisk information och utveckla en webbtjänst för BIS för attöka tillgängligheten till informationen.Rapportens kunskapsbidrag är en analys av standarder för geografisk information som är relevantaför järnvägsnätet.

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.

Grönområden är viktiga inslag i städer, de tillför många positiva bidrag till människors liv. Många studier visar på grönområdens positiva effekt på folkhälsan genom bl.a. minskning av stress och ökning av fysisk aktivitet. Närheten till dessa områden är mycket viktiga, studier visar att avståndet till ett grönt område bör vara max 300 meter från människors bostäder för att de ska användas mycket.Stockholm är en relativt grön stad, här finns många parker och andra naturområden som bidrar till att ge staden dess karaktär. Grönområdena i staden är också mycket populära, över 90 % av invånarna besöker ett grönområde minst en gång om året och 45 % är där varje vecka.

Industrial buildings are increasing all over Sweden. Farmers are building new modern facilities and the government chooses to build new halls to invest i youth sports. Glulam is the most common framework but there are limitations because of the transport. Therefore, there is a need to develop new solutions to increase the use of glulam.The maximum torque in the eaves was found in the frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated.

The purpose of this master thesis was to examine how the corporations quoted on the A-list on the Stockholm Stock Exchange were affected by the introduction of IFRS 3 Business Combinations. Their opinion about the accounting rule and the acquired goodwill in particular was focused as well. The authors wanted to see if there were any changes in ROE, return on equity, after the introduction of the new accounting standard.Data for this study was collected through interviews, questionnaires and annual reports. Interviews were held with corporate accounting managers of Assa Abloy, WM-data, Electrolux, Ericsson and SCA. Questionnaires were sent by e-mail to 50 companies and were answered by 30 of them.

The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.

The idea with constructions made out of prefabricated elements is that it should be quick and easy to build as the demands for lower production costs, increased profitability and shorter production times are constantly increasing. High accuracy in measurements and well-balanced tolerances is required to achieve this. The fact that the concrete-elements doesn?t fit and that damage occurs during assembly is a highly topical issue even though we now have methods and systems that make this high-intensity construction possible. Through this report we want to highlight the problems that cause the dimensional and tolerance problems and give suggestions on how to come to terms with these.

AbstractIntense competition in the building industry has forced building companies to develop highly efficient and optimised building solutions. This project, with a loggia that works both as an extended living room and a glazed balcony offers a highly economic viable alternative to standard balconies. This alternative is likely to attract build master since the area of the loggia will be part of the apartment area, i.e. included in the area for rent..
