Prototyputveckling av digitalt styrsystem för torkskåp

Nimo Verken AB is the leading producer in the Scandinavia of drying cabinets. The construction has, with small changes, been the same since the 70s with a thermostat and a timer as controlling system. There was a wish to develop a modern cabinet which showed remaining time on a display and with energy saving functions.In this report we go through how it is possible to implement a digital controlling system, where remaining time is shown on a display and where it is possible to choose a preset ?program?.The report first presents the fundamental theory for a PIC, where we describe the different registers, how interrupts are handled, the internal clock function and how data is sent to control the different parts of the construction.Next the report presents and describes the new hardware that is needed, such as the encoder, the temperature sensor and the display.After the theory we describe how the program in the PIC may be drafted. Last in the report we have the result of the tests of the temperature variations and the accuracy of the time..

Migration of a very large database with Swedish demographic data, using Microsoft SQL Server

SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

Nya gränssnitt mellan människa och hav: interaktiva teknologier för ett marint upplevelsecenter.

This thesis project explores technologies that enable people to experience the world through animals' senses in order to spark interest in and awareness about the marine environment and its inhabitants. The project is carried out as part of a planned ocean themed science center. The purpose is to explore how a greater understanding of the marine environment can be achieved using interactive technologies. The thesis is based on a theoretical framework consisting of academic works on experience, learning in a museum context and sensory perception. Our proposed designs are a series of, primarily, wearable devices that translate sensory experiences and principles from the marine world to humans.

?Var är du?? En studie om virtuella kollaborativa designprocesser i en studiemiljö

The design process of an interaction design student is mostly collaborative and computer oriented. Based on this, it?s hard to believe that we have not yet found a tool that will facilitate our needs. With this in mind, which elements do we need to promote collaboration in a virtual design process? This thesis will include design processes, collaboration, creativity and virtual awareness, amongst others.

Förekomst och grad av osteokondros i distala radius och ulna hos konventionellt och KRAV-uppfödda slaktsvin :

The occurrence and degree of osteochondrosis was studied in 64 pigs raised in conventional systems (45) or organically according to KRAVs principles (19). In this blind study the growth plates of distal radius and ulna were examined macroscopically and radiologically searching for pathological lesions. One significant difference was shown in this study. Conventionally raised pigs diagnosed with osteochondrosis had more severe lesions in the distal growth plate of radius and ulna than the corresponding group of pigs raised organically. No significant difference was shown between the groups when all pigs were included. .

En iPad-baserad ritningsbehandlare

In today?s society, it becomes more common with tablets, that makes us interact with computers in a whole new way. For example these are used to read and write e-mails, surf the web and playing games. Another manner of use of these tablets is to read and edit PDF documents. PDF handling is often meant to be used in books and inregular text documents, but it could also be used in the management of drawings.An industry that would benefit greatly from the use of tablets for this purpose is the con- struction industry.

"Challenges when implementing standardized and processes within a customer service unit"

 Abstract  Interest in Lean grows and spreads to the public from industrial and service sectors. Lean is currently used in administrative processes and it is called Administration but can administration be Lean? The aim of our study is to develop a useful model for a successful implementation of Lean Administration by using various scientific articles, books and information from the case study.The part of the purpose is to: ? Identify critical success factors that arise? Identify the challenges arising from the implementation of Lean Administration.We have studied a Division within Distribution at GE Healthcare in Uppsala. The model that we have developed provides challenges and success factors for a successful implementation.In order to succeed in implementation, a culture that promotes continuous improvement must exist in the organization. A key success factor is to understand Lean Administrations structure and principles.

Vilka möjligheter har barn till fysisk aktivitet i fritidshem? : En intervjustudie

This study is based on a statistical analysis of fundamental key ratios on the Stockholm Stock Exchange during the period 2004-2012. In total 35 financial ratios of 90 companies were tested, ultimately five ratios remained within the 5% significance level. These ratios were ROA, P/B, Total Yield, EV/EBIT and Operating Margin. A custom made investment model was created based on the purpose to achieve a risk-adjusted excess return. The results in general did not show any significant difference in return between the model's portfolio and index.

Aktievärdering: en studie av finansanalytikers val av värderingsmodeller, värderingsfaktorer och informationskällor

Denna uppsats syfte är att studera finansanalytikers val av värderingsmodeller, värderingsfaktorer och informationskällor på den svenska aktiemarknaden under hösten 1998. Det är av stort intresse att analysera finansanalytikers arbetssätt, vilka värderingsfaktorer och informationskällor som är väsentliga vid aktievärdering, då flertalet forskningsresultat sammantaget styrker det faktum att finansanalytikern har en aktiv roll att fylla på aktiemarknaden. För att uppnå studiens syfte genomfördes en enkätstudie som bygger på Olberts undersökning från 1992 rörande samma ämnesområde. Resultaten från enkäten visar att finansanalytikerna huvudsakligen utgår ifrån fundamental analys vid värdering av aktier samt att de samlar in information ur årsredovisningen, delårsrapporter och från diskussioner med företagsrepresentanter. De värderingsfaktorer som finansanalytikerna främst prioriterar är vinst/aktie, kassaflöde samt ledningskompetens..

Kvalitetssäkring och processtyrningav ytstruktur på lackerat objekt

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Ryttarens tygelsignalers inverkan på hästens beteende och trycket i tyglarna

This essay derives from the concern that horses ridden with a bit in their mouth can be subjected to strong pressure from the bit if the horse and rider do not understand each other. The horse's mucosa membrane and the tongue are very sensitive tissues (Cook, 1999; Manfredi, 2005; Oliveira, 2005; Terada, 2006) and the bit can then be a source of pain and discomfort. The training of the horse should therefore always be a step by step process and as the horse develops difficulties are increased. Oliveira (2005) suggested that high demands can be placed on the horse but to be successful in the training it is essential to be content with small progress and reward the slightest desired response from the horse. This corresponds with the principles of operant conditioning with negative reinforcement.

En fundamental investeringsmodell : Portföljanalys på Stockholmsbörsen

I den här undersökningen har vi konstruerat en investeringsmodell, baserad enbart på finansiella nyckeltal. Modellen riktar sig mot privata aktiesparare då vi märkt att investeringsmodeller och andra existerande analysverktyg för aktiehandel är komplicerade och i regel avsedda för professionella aktörer.I modellen ingår fem nyckeltal som vi har valt utifrån tidigare forskning samt egna preferenser. Nyckeltalen har beräknats för 24 börsnoterade företag på Stockholmsbörsen 1991-12-31 - 1995-12-31. Syftet med investeringsmodellen är att bilda en aktieportfölj som vi prognostiserat ska ha genererat högre avkastning än jämförbara marknadsindex under perioden 1995-12-31 - 2009-12-31. Aktieportföljen inkluderat/exkluderar företag beroende av ifall de uppfyller investeringsmodellens nyckeltalsgränser.Resultatet av undersökningen visar att vår aktieportfölj var överlägsen markandsindex.

Prins Eugen som monumentalmålare : A study of mural painting as an artform

The aim of this essay is to examine the relationship between picture and room, between wallpainting and architecture. The basis for such exploration is the mural painting in Sweden at the turn of the 20th century, and the artist in focus is Prince Eugen (1865-1947).His works "Sommar"(1904), "Rimfrosr"(1909) & "Staden vid vattnet"(1922) and the rooms in which they are in make for an anlysis concerning how the totality of the space is experienced by the viewer.The main issue in mentioned expeience is how the mural is perceived with regard to the other elements in the room. And here, the walls' "flatness" enhancing its decorative qualities plays in. The problem with a mural built on the principles of perspective becomes evident when a wall is seen to vanish through the painting of an illusion on it..
