Turbulens är ett väderfenomen som har orsakat många olyckor och incidenter. Speciellt farligt är klarluftsturbulens eftersom fenomenet ej är synligt för blotta ögat, samt att det kan uppstå mycket plötsligt. Mycket pengar och resurser har lagts ned för att ta fram system som skall kunna detektera och automatiskt rapportera turbulens. Denna uppsats beskriver kortfattat hur några av dessa system fungerar samt hur systemen skall bidra till att piloter lättare skall kunna förbereda för eller undvika turbulens. Uppsatsen beskriver system för prognostisering, detektering och automatisk rapportering av turbulens med tyngdpunkt på klarluftsturbulens..

Inom militär flygindustri är produktdatahantering i produktlivscykeln och utveckling av logistikstöd centrala områden för att hantera krav och kostnader. Senaste strategin för dessa utmaningar grundar sig i modellbaserat konstruktionsunderlag ? model-based definition (MBD). I detta perspektiv står disciplinen teknikinformation inför förändringsarbetet att utnyttja möjligheterna med MBD. Förbättringar i presentationsmetod för illustrationer och effektivare arbetsmetoder för produktion förväntas.Detta förändringsarbete undersöktes genom en fallstudie av Saabs konceptutveckling för teknikinformation till stridsflygplanet Gripen NG.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

The purpose with the paper is to theoretically investigate how sensory experience and positive affect in contact with outdoor environment can promote health by 1) develop a model of the sensory and emotional processes based on multiple code theory (Bucci, 1997) and 2) examine if this model can increase understanding of the processes that takes place in outdoor recreation, the way this is described in environmental psychology research and theory. The paper starts by introducing research and perspectives concerning outdoor recreation. Different theories of nature?s health promoting effects are described. These include the restoration theories of Roger Ulrich and Steven and Rachel Kaplan, theories more concerned with outdoor activities and a theory combining these two perspectives called instorative theory. After this sensory and emotional information processing is examined through the works of Wilma Bucci and Jean Ayres. Antionio Damasio?s theories of emotion and Daniel Stern?s concept of vitalityaffects are than introduced to extend this reasoning.

This study is a comparative study of the occurrence and function of information literacy in the curricula of the Swedish and Bavarian Gymnasium and investigates the occurrence of the term ?information literacy? and shows through what other linguistic means the notion of information literacy is expressed in the curricula. The study also wishes to analyze how the notion of information literacy manifests itself in the different school systems. Relevant textual passages of both curricula are compared to each other through the theoretic lens of Bruce?s phenomenographic model of information literacy.

The purpose of this MA thesis is to examine the computerisation of sources that are of interest to genealogists. The primary focus of the thesis is an empirical study, by using a questionnaire addressed to 118 genealogical societies in Sweden, in order to find out what kind of computerisation is being performed by these genealogical societies and what their opinion is of the computerisation of sources of interest to genealogists. The result of this questionnaire has shown, together with printed and electronic material, that there is a good deal of interest from genealogical societies in the computerisation of sources. About half of the genealogical societies who answered the questionnaire are computerising sources themselves and the societies have a positive view in general of the computerisation that is being done and of the increased usage of modern information technology in genealogy. There are on the other hand certain issues that are being discussed such as the important question of the quality of the computerised material.

The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.

This examination paper is about the potential for Solar cells on apartment blocks. The technology with using solar cells for manufacturing electricity, has been on the market for a while, but recently the new installations of solar cells has increased. Solar cells are suited for placements on buildings but are expensive to obtain. The municipal real-estate company is interested in solar cells but wants to know more before they invest in the technology. This report contains an account of the solar cell and a guide to how a connection to the grid is accomplished.

In outdoor education the empirical outdoor experience is an important basis for a learning process ? the teacher can affect learning with the choice of location. In order to develop the model in school, we need to build on teachers' perception of how their every day schoolwork looks like. This paper takes as its starting point at three teachers' perception of their learning environment and outdoor environments as well as a theoretical model of the site's importance in the learning process. The paper addresses both the importance of a structured and a unstructured meeting with outdoor sites.

Målet med denna studie är att undersöka i vilken utsträckning och i vilka sammanhang det könsneutrala pronomenet hen används bland gymnasieungdomar, i förhållande till redan etablerade neutrala uttryck som exempelvis den, han eller hon och vederbörande. Dessutom söker studien upptäcka eventuella skillnader i attityder och bruk av hen mellan olika grupperingar. Finns det kopplingar mellan graden av acceptans respektive bruk av hen och graden av språklig, kulturell inriktning i de gymnasieprogram eleverna går? Sammanlagt 200 elever på gymnasieskolan har i en enkätundersökning fått svara på frågor om hur de förhåller sig till hen och andra könsneutrala pronomen, såväl i sitt eget språkbruk som i acceptansen till andras. Hälften av eleverna går på ett program med språklig och kulturell inriktning och hälften på ett program med naturvetenskaplig inriktning.

A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

Companies acquiring ERP systems are often dissatisfied with the project and therefore consultancy firms wish to make use of project models in order to achieve success in implementations. Since research on ERP implementations in service companies is limited, there is a need for mapping of critical activities in implementation projects in this line of business. Under these premises, the purpose of our master thesis is to develop a model for implementation of ERP systems, specified in activities, which can be used by mid-sized consultancy firms with mid-sized qualified service companies as customers.A literature study including project models, modern models and methodologies for ERP implementation, commonly existent activities, success factors and system development methods was carried out. Starting out with this, a theoretical model for ERP implementation was generated. In excess of this, a case study was conducted, where the implementation of the ERP system Microsoft Dynamics AX at the service company Eurostep, performed by the consultancy firm Medius, was studied.

This thesis aims to describe how enterprises can approach and reach older citizens inorder to sell new technology products. For that they need information about aspectsaffecting elderlies purchase decisions regarding these kind of products. The study isbased on 13 qualitative interviews where we have applied semi structured interviews andobservations of the elderlies behaviour towards an Ipad which we used as a study objectduring the interviews.The results of this study shows several aspects which affect the elderlies purchasedecision regarding new technology but it all comes down to one matter, lack ofknowledge. In order to overcome that obstacle, enterprises need to modify theircommunication strategy. They will be needing information about elderlies preferencesand their self-image, meaning how they perceive themselves which is connected to howreceptive they are towards new technology.

The river Göta Älv reaches between Vänern and Gothenburg and is the main raw water source for Gothenburg that supplies about 700 000 people with water. To protect and maintain a high water quality, continuously samples and water analyses are made throughout the river. In 1998 a protection area was founded between surte and Lärjeholm where the raw water intake is. This was made to increase the awareness of the importance to protect the water. However, there is a lot of contribution of untreated stormwater to Göta Älv within the protection area.Göteborg Water and Sewage Works commissioned this thesis where two areas, Tagene industrial area and Kärra residential area, with untreated stormwater outlets within the protection area are studied.

This is an explorative study about subject indexing of a special collection of books, administered by the John Andrén Foundation at the library of Ystad. The study summarises a number of theoretical perspectives as well as some practical instructions on how to carry out the task. Theories have been placed into five different groups according to their various approaches to subject indexing. These have been analysed in regard to their usefulness to the Andrén collection. The authors have tested and evaluated six practical models on a selection of books from the Andrén collection.
