Avdelningen för reaktorteknologi på Alfa Laval har identifierat svårigheter vid förmedlingen av kunskap till potentiella kunder. Examensarbetet innefattar utveckling och produktion av en film avsedd för utbildning och marknadsföring av Alfa Lavals flödesreaktorer, ART® Plate Reactors, för att förbättra Alfa Lavals sätt att förmedla kunskap till och fånga intresse hos potentiella kunder på mässor.Målet med examensarbetet är att filmen ska användas på kemiteknikmässor där reaktorerna ställs ut, och syftet med arbetet var att med mässbesökarnas förkunskaper som bas utveckla en film som väcker intresse och samtidigt fungerar som ett lärandemedel.Genom intervjuer har information om hur mässor går till, önskemål om filmens utformning, samt bedömning av besökarnas förkunskaper samlats in. Dessa intervjuer, samt litteraturstudier inom området för kemiska reaktorer och lärande med animation och kommunikation på mässor har legat till grund för arbetet med framtagandet av filmen.En storyboard utvecklades, och lade grunden för produktionen av filmen som gjordes i samarbete med filmbyrån Upper/First i Malmö. Produkten av examensarbetet, filmen, finns att se påhttp://youtu.be/PyoX3mVXuYc.Nyckelord:Storyboard, Multimodalt lärande, Kontinuerliga flödesreaktorer, Reaktorteknologi, ART® Plate Reactors.

AbstractThe purpose of this study is to examine how children interact with each other and what social positions they assume when using the learning pad. The social positions reffered to is the Owner, the Participant and the Spectator, defined by Ljung Djärf (2004). According to Ljung Djärf (2004), the Owner is defined as the one in control of the mouse and keyboard. The Owner is expected to be in charge of what is happening on the screen. The Participant is typically found on a chair near the computer.

The governing set of regulations for structural engineering in Sweden used to be Boverket, BKR. However in the beginning of the 21st century a changeover to new regulations, the Eurocodes, started.The transition was completed in year 2011 when the Eurocodes became the mandatory design work policy for all countries within the European Union. The Eurocodes were implemented to simplify and remove potential barriers to trade that may exist when countries have different design rules.  Since the changeover it has been important for all construction companies to update their knowledge base and their design software.When comparing the two calculation processes they seem similar, but there are a couple of differences worth noting.  With the new regulations, engineers will find that the process when designing joints in timber structures has changed.  What used to be a fairly easy and straight forward calculation procedure has now become tedious and time consuming.The objective of this degree project is to present a product, a dimensioning tool that will help structural engineers when computing lateral load carrying joints in timber structures.The degree project is made up of two parts where the first part is the written report describing the background and theory behind load carrying computations. The second part of the project is the actual dimensioning tool which includes several worksheets in Microsoft Excel. The program treats single and double shear connections of the following:Nail jointsScrew jointsSteel plates (thick and thin types) The user can edit the following parameters:Type of plate/ number of shearsStrength class of timber membersMember and plate sizeType of fastenerDiameter of fastenerLength of fastenerYield moment of fastenerkmod and partial factors for design load carrying capacityThe dimensioning tool was created and developed in collaboration with structural engineers at the company Byggteknik AB.

The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.

I dagens samhälle projekteras alltmer komplicerade byggnader, samtidigt som projekteringen av den enskilda byggnaden skall ske i en allt snabbare takt. Detta har onekligen bidragit till att det blivit allt vanligare med datoriserade hållfasthetsberäkningar, som ofta baseras på finita elementmetoden istället för de klassiska handberäkningmetoderna. Frågan som många då ställer sig är huruvida resultaten skiljer sig åt mellan de olika beräkningsmetoderna, och i så fall på vilket sätt? För att kunna besvara denna fråga har detta arbete inletts med en genomgång av de klassiska handberäkningsmetoderna, vilka bygger på gränslastteori. De viktigaste egenskaperna för varje metod har redovisats och förklaras.

In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

The park at Svaneholm is a place, the history of which is very little known today and the needfor better knowledge has been the cause of this investigation. The essay is primarily limited tothe time from late 17th century up to the end of the 18th century and takes stand on profoundinvestigations in accessible map-and archive material. The results presented show a manorhill, which during the course of a hundred years was subject to several changes and in bigparts consisted in other than park/garden.Burman related to the manor hill containing a cowshed, a large dam and a parterre garden isix quarters and it is plausible to think, that this establishment generally was built as producedon the plate.In the 18th century the construction is being changed, they go on building at the cowshed andin 1707 there are totally 268 livestock on the farm. In 1723 the garden is represented in amuch bigger scale than on the plate from the 1680:s, but it is not possible to tell, whether it isnew or not.Parts of the parterre garden is remaining during the whole of the 18th century, for the leastuntil it is being squared, but on two of the squares there was built a riding-groundMoreover the cowshed burnt down and was only partially reconstructed.The image given by the archive material is at the same time variegated. The inventory list ongarden tools from 1726 gives an image of gardening more directed to growing and pathshuffling, while the possibilities of keeping the parterres were fewer (e.g.

GBD-Storage Systems is a company that provides the industries with products for efficient storage.The company produces pallet racks and accessories like cassettes and extending units. The companyhas also supplied tire racks for a number of tire companies. The company's CEO Gunnar Berglund hasfor some time had an idea to improve the working situation of the workers on tire firms by allowingthe wheels to be handled by a counterbalance truck. The current situation poses numerous heavy liftswhen the tires are handled and therefore is hurting the workers.This thesis has been aiming at helping the GBD-Storage Systems by developing a concept of howan accessory to counterbalanced trucks can be designed to cope with the wheels. This concept willthen be produced as prototype by the company.

Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.
