Kalkylering av bearbetningskostnader
At a manufacturing company, due to the competition the price is reducedtowards the manufacturing cost. Therefore it is important to maintain control ofones costs and keep calculations up-to-date.This thesis deals with cost accounting at a aluminium-processing company. The report focuses on calculating machine cost per hour since the manufacturing costs are the major part of the total product cost.Managers on the company believe that the costs they use in calculations todayneither is up-to-date nor advantageous in a market aspect and due to that their calculations need to be revised. The machines cost per hour is a major part in the manufacturing calculation. The company wants to provide a competitive price that also covers their costs.
Camp Vamp - Att ljussätta en dansföreställning med skiftande förutsättningar
I work on a lighting design for a dance performance to be on tour. A lighting design adapted for
three different conditions was made:
- One comprehensive where I allow myself a great deal of creative freedom, adapted for the
stages with major technical conditions.
- One smaller version for stages with less equipment and with less time for preparation on
site.
- One design for very simple conditions.
I also examine the specific differences between typical theatrical lighting design and typical dance
lighting design, and the best way to prepare for the hands-on stage design phase..

Effektiv partiformning : analys och tillämpning på Uppåkra Mekaniska AB
This paper is the result of a case study conducted at Uppåkra Mekaniska AB during the spring of 2006. The task that was presented by Uppåkra was to develop a basis for a decision for the planning activities at the company, so that in the future they can create lot-sizes which are based upon a total cost perspective. Total cost in regards to lot-sizing is defined as the sum of the administrative reordering costs and warehousing cost per stock keeping unit.To collect data a series of interviews and observations were conducted. This data was then used during the lot-sizing simulation and analysis. The 15 units that the simulation was conducted on were grouped into three item classes depending how many different machine setups they required during the production process.
Synchronous Latency Insensitive Design in FPGA
A design methodology to mitigate timing problems due to long wire delays is proposed. The timing problems are taking care of at architecture level instead of layout level in this design method so that no change is needed when the whole design goes to backend design. Hence design iterations are avoided by using this design methodology. The proposed design method is based on STARI architecture, and a novel initialization mechanism is proposed in this paper. Low frequency global clock is used to synchronize the communication and PLLs are used to provide high frequency working clocks.
Mjölkkyl till espressomaskin : Impressive cooler
The project was made in cooperation with Coffee Queen AB, Arvika. The task was to develop and design a new cooler for the milk to Jura Impressa X9, an espresso machine. The good assistance with staff at Coffee Queen and engineers in China and at KPA in Karlstad led to a solution to the problem. It was a long road to get there, many different concepts was developed. When the day came to decide which concept to work with, the choice stood between two different technical solutions.

The thesis give a brief introduction to current achievement in conservation research and general profile of industrial conservation practice. Based on case and theory study, Yu?s design approach is carefully applied to an industrial area Nyhamnen in Malmö and a design proposal is produced.
Design av Tjänster : Komplex affärsutveckling över tid och rum
Service Design is a relatively new, unexplored and exciting phenomenon that through an interdisciplinary work methodology designs services. A discussion has been going on for a long time regarding whether there is a difference between products and services. Services are often classified as immaterial, heterogeneous, non-storable and inseparable in relation to products. A question that arises is if something specific characterises the work methodology used regarding service design. The aim with this paper is thus to explain the work methodology when working with service design.
Operatörsunderhåll : Ett examensarbete om att använda 5S till hjälp för att förbättra operatörsunderhållet
As the final course in the education ?University Diploma Programme for Process Operators? there is a thesis in cooperation with a company required.This thesis is about operator maintenance and 5S made at Metsä Board in Husum.In this report you can read my opinions and conclusions based on literature studies and the interviews that have been made with the staff at PM6 (the paper machine).I chose to focus on the theory of lean, 5S and operator maintenance because it covers the area of this thesis.The operators shall do their rounds to make sure that the equipment works fine. They shall also write down things that they notice in a checklist. This is not done as it should be and the question is: can this be solved by using 5S?My conclusion of this thesis are:Better review of the task so that everyone is involved.
Bättre åtkomst till avverkningstrakter med anpassat marktryck från avverkningsmaskinerna
The global climate-change means increasing mean-temperature and higher precipitation in Sweden, which leads to shorter periods of frozen ground in the forest. At the same time the harvesting machines are getting bigger and more powerful. The forest industry aim at an even wood flow, and the ground damage has to be as low as possible. The two biggest causes for ground-damage is the bearing capacity of the forest ground and the ground-pressure of the harvesting machines. The aim of this study was to find out some rules for the machine choice considering ground pressure, when harvesting on ground with low bearing capacity.A field study, using a Valmet 890.3 forwarder, was carried out where different ground pressures and their effect on the ground were tested on two different types of ground.Additionally, an inventory of damaged harvesting grounds was made.
Kreativ design som ett sätt att lösa komplexa problem : Ett snapshot av designprocessen vid utveckling av en trailer för ett fiktivt tv-spel
A current issue today is to try to implement creative design as a way to solve wicked problems in scientific contexts such as HCI. Since the problems are wicked, they have no given solution which makes the traditional methods inadequate. In these cases, creative design can be an alternative. Creative design is not used in scientific contexts because it is viewed as something unaccountable.In this essay we argue that creative design not necessarily have to be unaccounted. We discuss various views of creative design and translate theory to a practical context.
Ultraljudssvetsning: ett komplement eller ersättning till symaskinen?
AbstractThis bachelor thesis has been assigned by the company ACG Nyström, Borås. ACG Nyström is working in cooperation with a Swiss company named Jentschmann AG. Jentschmann is a manufacturer of ultra sonic welding machines which ACG Nyström is marketing in Scandinavia and the Baltic States. On behalf of Jentschmann AG the company has the aim to introduce the ultra sonic welding technique to new companies.The aim of this thesis is to compare traditional sewing machines with ultra sonic welding machines within two textile areas, protective clothing and outdoor living.Two investigative questions have been formulated for this purpose: what are the differences between a sewing machine and an ultra sonic welding machine? Is it possible to replace the sewing technology with ultra sonic welding? These stand as guidance for this paper.To gather knowledge interviews, literature studies, and tests on two different ultra sonic welding machines were performed.
Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :
Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.
