Förpackningshantering i det dolda : En studie om hur den interna hanteringen kan synliggöras och förbättras.
Handling materials and packaging, which is the focus of this study, requires efficient logistics, both internally and between companies. To achieve an efficient material flow, good information systems, whose role is to collect, store, process and distribute information, are required. The assumption that packagings are handled in an efficient manner is currently not a matter of course, when many companies do not prioritize the internal management of the package.The purpose of this report was to investigate how medium-sized businesses working with distribution and handling of spare parts packaging can improve their internal management of packaging. In order to answer the purpose, we have used an abductive process and a qualitative data collection. The study had Logistic Center Ljungby (LCL) at Electrolux Laundry Systems (ELS) as a case company and two other respondents, Nibe in Markaryd and Enertech in Ljungby.

En app för smartare måltidsplanering
This thesis is based on design theory about how to build an application for the mobile platform, a scientific analysis and an application for grocery shopping and meal planning. The thesis also contains a valuation of the research and of the application. The valuation of the application was done by a usability test and an analysis of the results of the test.The application of the thesis has an easy navigation system, which is time saving and simple to use. Finding recipes with the associated ingredients is a quick fix. The search function can be used for searching freely after recipes as well as for separate ingredients. That makes it possible for the user to create own recipes from available ingredients.

The goal is to identify weak points in the chillchain and to se how wrong temperatures affect the flowers. The results can be a help to secure the chillchain.Method:The work started with a problem; map the distribution of cut flowers with focus on temperature losses. Data was collected on the basis of this problem, then analysed, and finally conclusions were drawn.Conclusions:The affect handling and distribution has on a cut flower is very complex.
Analys av leksaksrobot, skapande av monster
During spring 2009 a three meter tall and laughing robot was developed in collaboration between Royal Institute of Technology and Royal University College of Fine Arts. The robots function and esthetics is based on an existing toy robot called Elmo. Elmo is 30 cm tall but now the goal was to make it 1000 times bigger in order to present it on the spring exhibition of Royal University College of Fine Arts. Due to only four months of developing and building time a demand of fast determination and good planning was required. In order to make a good structure for the project it is divided into five phases: Analysis of Elmo, planning, concept development, detail construction and finally product development and testing.In the first phase valuable knowledge is obtained according to the movements and geometry of Elmo.
Styrsystemets roll i balanseringen mellan kontroll och empowerment : En kartläggning av ett styrsystem och varför användningen leder till observerade effekter på personalen
Problem discussion: That empowerment and autonomy can lead to desirable effects on employees is clear. Previous research has found correlations between empowerment and e.g. motivation, job satisfaction, productivity, loyalty and commitment. However, a control problem arises when employees have more freedom in decision-making which could potentially lead to undesirable outcomes. It thus becomes a type of dilemma for management and managers where you have to try to balance a restrictive use of the control system (to maintain control) and an enabling use (to promote empowerment).Purpose: The purpose of this study is therefore to identify how a company can use its control system in order to achieve empowerment while maintaining acceptable levels of control.
Vidareutveckling av provplattform för mätning av kosmisk strålnings inverkan på DRAM
Sammanfattning: SAAB Communication i Linköping sysslar med konsultverksamhet mot ett flertal nationella och internationella företag inom både den civila och militära sektorn. Fokus ligger på flyget med uppdrag inom telesystem, radiosystem, signaturanpassning, EMC, atmosfärisk påverkan mm. I det sistnämnda ingår även kosmisk strålnings inverkan på elektronik. Den fortsatta miniatyriseringen av elektronik, speciellt minneselektronik leder till ökad känslighet mot den kosmiska partikelstrålningen som ständigt regnar ner på jorden, därför är det extra noga att minnen testas innan de sätts i bruk vid flygburna system. Syftet med detta examensarbete är att konstruera en provplattform som registrerar fel som uppkommer i ett DDR2 SDRAM minne vid påverkan av den ovannämnda strålningen.

Fattigvården i Gustavsberg 1869-1924
With the help of large amount of archive material I have examined how Gustavsberg in Värmdö were affected by the great labor migration in Gustavsberg porcelain factory during the period 1869-1924. I have chosen to investigate how the municipality dealt with the poverty relief issue out of the labour immigration perspective. To my surprise I found out that Värmdö was not responsible for Gustavsberg in the poverty issue. The workers belonged to the factory, which had a relatively well-developed system of poverty relief in place. This is not to say that the workers received any support from the factory to any great extent.
Marknadsundersökning: Lämpliga flygplan med avseende på start- och landningssträckor för Bunge flygfält
In many products a compromise between ground clearance and the required space to store the product has to be made. This problem attracted the attention of the authors of this thesis.The objective of this project is to develop a functioning solution to a foldable wheel. The solution should be applicable to several types of product groups. A limitation for this work has been made so that the work only covers solutions for lighter vehicles.The purpose is to drive this project forward, so that a solution can be found. Furthermore the purpose of the report is to clarify how the authors proceeded to design and construct the wheel according to a fixed specification.

Mot en delad framtid? : Mendeley som exempel på vetenskaplig kommunikation online
The last few years have been characterised by increasing online communication and the emergence of social media, made possible by Web 2.0. In society as well as in research, social media is used for knowledge produc- tion and networking. One example of this is Mendeley, a social reference management tool. With answers from users all over the world, this study investigates the use of Mendeley, if the respondents use other social media and if all of this affects scientific communication. The aim is also to study what the respondents think about the future of scientific communication and if this can be related to current tendencies.The theoretic framework for this study is based on Leah Lievrouws research on the Cycle of Scientific Communication and the relationship between the ?Little Science 2.0?-scenario and the ?Big Science Retrench- ment?-scenario.A qualitative web based survey was conducted (41 answers) and complemented with an interview with a professor in environmental sciences.
Färsk ved till Hallstaviks pappersbruk :
Hallstaviks papermill is an industry plant within Holmen Paper. Hallstavik is a mechanical
mill and produce newspaper and journal paper. During year 2000, Hallstavik used
approximate 1.200 m3f spruce, either as logs or chips from sawmills. Due to that the
production is running continuously the mill also needs raw material at the same rate. At some periods the supply of raw material cannot keep up pace.
