Elever ska enligt kursplanerna i teknik få förståelse för de tekniska system de möter i sitt dagliga liv. Genom att eleverna får kunskap om teknik i allmänhet och tekniska system i synnerhet får de möjlighet att påverka sina liv som medborgare i en demokrati. I litteraturen saknas idag studier om elevers uppfattningar om tekniska system. Syftet med detta examensarbete är därför att studera vilka vardagsuppfattningar elever har om de tekniska system de möter i vardagen. Studien utgår från systemteori vilken ger en möjlighet att utnyttja det gemensamma mönster som kännetecknar analys av system.

This is a bachelor thesis about arable land in Varberg, from sustainability and it?s relation to local government and management. Arable land has become more important as a natural resource from a global point of view and in concerns of higher demands of food supply, as a result of population growth, higher consumption worldwide and climate change. But the arable land in Sweden is being exploited an increasingly rapid pace and the arable land in Varberg is not an exception of this development. The issue is most topical and the discussion holds questions about a declining agricultural sector, the formal and administrative protection of arable land and because other interests of land use often is given higher priority in community development and planning.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

Rapporten är ett examensarbete på 20 poäng och utgör avslutningen på min utbildning till teknologie magister i fysisk planering (180p). Arbetet har gjorts under hösten 2000 och vintern/våren 2001. Inledning Samspelet mellan stad och land är en förutsättning för ett långsiktigt hållbart samhälle, men ofta framställs landsbygden med sina mindre tätorter som oviktiga och betydelselösa och de flesta små kommuner kämpar hårt mot stagnation. För den breda allmänheten är dessa kommuner främst en temporär rekreationsplats. Utredningen vill medverka till att stärka och medvetandegöra landsbygdskommuners betydelse i allmänhet och Torsås kommun i synnerhet. Utredningen har valt att analysera hur landsbygdskommunen Torsås kan uppnå en positiv framtidsutveckling och arbetsmetoden är även tillämpbar för andra kommuner. Arbetet belyser även den krassa verklighet som idag råder vid nya detaljhandelsetableringar, där marknadskrafterna i princip har fritt spelrum och där resultatet ofta blir stagnerande stadskärnor och landsbygdskommuner. Syfte Syftet har varit att utreda vilka förutsättningar som finns för en framtida handelsutbyggnad i Torsås kommun och att belysa det komplexa samspel mellan olika faktorer som krävs för att nå en positiv handels- och samhällsutveckling.

The purpose of this study is to examine how risk is perceived by the urban architect's in the region Dalarna, as well as how this is reflected in their everyday work with risk and decision- making according to urban planning. The ambition is also to show how their risk awareness could be improved. The study is written in cooperation with Länsstyrelsen Dalarna as a part of their regional long-term goal to improve the region's proactive risk' and crisis management. The study is based upon 12 semi-structured interviews with local urban architects conducted during the summer and autumn 2007. The result shows that some architects are motivated for working with risk and think that risk awareness should be integrated in their everyday work, while others are not motivated and think that risk is more of a passing trend.

When using the digital halftone proofing systems, a closer print match can be achieved compared to what earlier couldbe done with the analogue proofing systems. These proofing systems possibilities to produce accurate print match canas well lead to producing bad print matches as several print related parameters can be adjusted manually in the systemby the user. Therefore, more advanced knowledge in graphic arts technology is required by the user of the system.The prepress company Colorcraft AB wishes to control that their color proofs always have the right quality. This projectwas started with the purpose to find a quality control metod for Colorcraft´s digital halftone proofing system(Kodak Approval XP4).Using a software who supports spectral measuring combined with a spectrophotometer and a control bar, a qualitycontrol system was assembled. This system detects variations that lies out of the proofing system´s natural deviation.The prerequisite for this quality control system is that the tolerances are defined with consideration taken to the proofingsystems natural deviations.

This examination report is a part of a program for Industrial organisation and Economics with specialization in Logistics and Management at Jönköping University. The report contains an analysis of the internal material handling at Kongsberg Automotive, and also an improvement proposal for a new material handling system.The aim with the report is to find a better material handling system and also make an analyse of the existing system. The goal is to shorten the distance for the operators when they order material, and also to increase the productivity.The investigation methods for the report have for the most part consisted of observations and interviews of key-persons who daily work in the production. During some time the actual material handling-system has been observed and some shortcomings have been discovered, and these are also discussed in the report.The shortcomings that have been discovered are for once the indistinct signal that should signal need of material in the production. Some other activities have also been discovered that does not bring any value into the final products.

Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

Arbetet berör ett större naturområde nordväst om Karlshamns resecentrum och är idag ett frekvent använt rekreationsområde för de boende i Karlshamns tätort. Dessa två faktorer, närheten till Karlshamns resecentrum och områdets värde för rekreation och friluftsliv är det som präglar arbetet och som i slutändan vägt tyngst vid utformandet av planförslaget. Målet med planförslaget är att det ska vara en möjlig och realistisk lösning på hur bostäder kan placeras i området. Hänsyn har bland annat tagits till topografin, markens beskaffenhet, skyddsavstånd, beräknad befolkningstillväxt och åsikter från boende i Karlshamn som utnyttjar området. Tillsammans har det utmynnat i ett planförslag gällande ett förbättrat friluftsliv samt tre altarnativ där framtida bebyggelse redovisas..

The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

Calculations are an important part of planning around a construction project. From concept to completion of the project calculation is a tool to try to predict the actual cost. During the production stage in particular, deviations occur which makes the actual cost different from the calculations.This thesis is done in collaboration with JM Residential Stockholm. The study includes a cost follow-up in which a comparison was made between the calculated production cost and actual cost for the five projects. The aim of the study was to observe the most common reasons that a project deviates from the calculated production cost and then summing these causes in a number of categories.

We have carried out a study of a classification system for the Swedish collection at The Royal Library in Stockholm from 1887. It was printed in 50 copies. The constructor, Bernhard Lundstedt, and his colleagues used it as guidance in lack of a catalogue. We regard it a local classification system. Little research has been done on old classification systems, but Francis Miksa points out the importance of examining them.

This degree project deals with the creation of a business system for Gamersneed Sweden. The system is divided into two parts, one windows appliction and one websolution..

Neoliberalism står för så mycket mer än att bara vara en ideologi som tar steget ifrån statens kontroll. Förutom att ideologin strävar åt ekonomisk frihet finns det också andra tydliga attityder som riktar sig till samhället i helhet; den enskilda individen, den anställde och staden. Neoliberalismen har påverkat planeringen mycket. Framför allt har tron på marknadens goda effekter förstärkts, medan staten har fått ett betydligt lägre förtroende och inflytande. De inblandade aktörerna har under senare tid blivit fler och detta gäller framför allt aktörer från den privata sfären. Stadspolitiken har också förändrats och har nu ett mer entreprenöriellt förhållningssätt och ett tydligare fokus på att marknadsföra staden.

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.
