Konstruktion av steghållare till brandbilar
High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.
Pilotförsök med ultrafiltermembran vid Gäddviks vattenverk
För att undersöka möjligheten att använda sig av membranfiltering vid Gäddviks vattenverk (Luleå kommun) har ultrafilter från två olika leverantörer utvärderats. Denna rapport behandlar de 6 första månaderna av anläggningarnas drift. De två leverantörerna är Zenon GmbH och Inge AG. Vid drift av anläggningarna har det största bekymret varit igensättningar (fouling) av membranen. Igensättningar måste kunna åtgärdas för att långvarig drift av membranen ska vara möjligt.

Tylö: Sauna Lighting
Tylö AB is the leading manufactor of sauna cabins in Europe, but there is a lack
of a sauna lightning produced by Tylö. The project of developing a new sauna
lightning series was assigned two students at the developmentengineering
program at Halmstad University. The main problem with lightning in the sauna
is the heat and security aspect. The selection fell on LED technology as the
lightning source, thanks to its small measures and low heat emission.
The work of constructing of a lightning armature which the capability of cooling
down the LED lightning was carried out during autumn ?06 and spring ?07.

Undersökning av modern reproduktionsteknik för
karosseridetaljer
En marknadsundersökning av förekommande metoder för digitalisering av karosseridetaljer. Olika skannertyper analyserades och en rekommendation av lämplig metod lämnades till uppdragsgivaren. Förutom punktantal beaktades även punktorintering, inskanningskostnad/tid, positioneringssystem och mätrymd. Uppdragsgivaren rekommenderades att använda en optisk skanner för projicering av fransar med ett optiskt spårningssystem. Då tillverkning skall ske i mycket små serier berördes även olika tillverkningsmetoder, som exempelvis hydroformning mot ett formverktyg av aluminium eller kompositcement.

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.
Verifiering av Kedertakstolen
The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH & Co. KG and this report has been made for their Swedish division Layher AB. The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn?t able to withstand the loads.

Storlommens (Gavia arctica) häckningsframgång relaterad till vattenkvalitet
This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen. .

Nosbits- och provbitssågning vid strängpressning av aluminiumprofiler : Förbättring av metod och utrustning
Rapporten behandlar arbetet med att göra arbetsmiljön vid en aluminiumpress säkrare. Idag sågas mindre bitar nypressad aluminiumprofil på ett sådant sätt att operatören bland annat exponeras för mycket heta spånor.Genom systematisk konstruktionsmetodik genererades ett antal koncept, dessa utvärderades och en detaljkonstruktion av två koncept genomfördes. Det ena av dessa två innebär att stänga av kylluften underifrån under sågningen medan det andra innebär en mekaniserad lösning med en låda på en vagn, vilken gör en operatörs närvaro onödig.Arbetet bedrevs på Sapa Profiler AB i Finspång och gav insikter i hur konstruktionsarbete på ett tillverkande företag kan gå till. Arbetet var mycket fritt och stort rum har lämnats för kreativa och nyskapande lösningar..
