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 is a bachelor thesis, written at the business studies institute, Uppsala Unviersity, exploring how digitalization has affected the Swedish book industry. This is done by studying how the introduction of the e-book has changed the way the publishers work and what problems and opportunities arise with the new way to publish and consume books. The technology optimists, that existed around the turn of the millennium, when the e-book came, made predictions along the lines of the physical book having ceased to exist within five to ten years. But the physical paper books do very much still exist, so haven?t the change happened as predicted? The purpose of this thesis is as follows: How has introduction of the e-book affected the relationship between the Swedish publishers and the book as a whole? This means that we consider the book as a concept, as a resource or product, and study how a change in this product affect publishers.The theoretical framework used is basically classical network theory.

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

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 thesis is concerning private brands on special display. ICA Gott Liv! was used as a study object and a latin square design was employed, using 2 ICA Kvantum stores. Two displays were built in order to compare which created the most awareness and interest, one with the best selling Gott Liv! product and one with four randomly chosen Gott Liv! products. The data was collected using triangulation, questionnaires, sales data and observations were conducted in the two stores. The results indicated that private brands works as well as manufacturer brands on special display and a display with four randomly chosen products creates more interest and higher sales than the display with the best selling product..

Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.

Produktnedläggning är ett sätt för företag att få bort produkter som inte presterar tillfredsställande. Tidigare studier har visat att företag med ordentliga rutiner kring produktavveckling har kunnat tillgodogöra sig flera fördelar i form av bland annat bättre lönsamhet och försäljning. Ändå har forskning visat att de flesta företag inte har några formella rutiner för nedläggning av produkter och att produktnedläggning inte ses som lika viktigt som andra produktaktiviteter. Av den anledningen studeras i denna uppsats hur väl utvecklade rutiner två utvalda företag har för avveckling av produkter.Syftet med uppsatsen är att undersöka hur två utvalda företags rutiner för produktnedläggning ser ut. Resultaten jämförs sedan med den teoretiska referensramen samt mellan företagen i fråga för att urskilja likheter och olikheter.Till denna uppsats har en kvalitativ metod använts för att klargöra hur företag går tillväga vid nedläggning av produkter. Genom intervjuer med AB Karl Hedin och Spendrups Bryggeri AB har empirisk data samlats in för att möjliggöra jämförelser företagen emellan samt med den teori som sammanställts.    De två studerade företagen har helt skilda förfaranden kring produktavvecklingar.

The competition amongst companies is getting tougher and the economic markets are getting even bigger with new products and businesses. One way for companies to differentiate themselves from the competitors is through packaging design. If the merchandise is to send a reliable and solid message to consumers, the attributes of the packaging must be consistent and uniform. If the different attributes are not coherent, the message loses credibility towards the consumer. Through the sent messages, the pack signals the products? expected quality and price.This paper includes two studies, in which the main objective is to discover and build understanding about Swedish consumers? perception of a product?s price depending on the pack?s design.

Författarna har haft ett samarbete med Panduro Hobby i samband med deras årliga miljökampanj. Syftet med examensarbetet har varit att med hjälp av befintliga produktutvecklingsprocesser och livscykelanalyser (LCA) ta fram en hållbar textil produkt med växtfärgning. Tanken var att konsumenter sedan själva skall kunna ta fram och växtfärga denna hållbara textilprodukt. Miljömedvetenhet och hållbarhet inom textilindustrin är ett aktuellt ämne. Trots det saknar dagens konsumenter förståelse för textilindustrins påverkan på miljön och har bristande kunskap om textila material för att kunna göra miljövänliga val ute i handeln.

During the year 2014, Artex AB has worked to launch a new product whose function is to locally purify the air. The product is a headboard and its purpose is to give the user clean air while sleeping. The air purifier has different speeds and it`s up to the user to choose which effect that will be on. To get the best experience of the product as possible, the air purifier shall be controlled by a mobile application. In that way the user can increase and decrease the fan speed, even when the user not is home.

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.

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.

Today's communication solution between the vehicle and trailer is one many see as anon-viable solution, then breakdowns on both the lights and cables are common. Now, anew innovation enters the market, a system that can transmit wireless control signalsbetween the vehicle and trailer.Parvus and Zap, the two solutions that the projekt group has come up with during thisthesis work carried out over the last year on Utvecklingsingenjörsprogrammet.Technologists Peter Jägevall and Christopher Åberg has developed this project on theirown. The group has developed various concepts and chosen to work on, two of them.The project has resulted in this report and a prototypeThe solution that the group has developed is a wireless communication between vehicleand trailer. The project team has developed new power-efficient LED lighting fixtures inorder to implement an internal power source in the trailer. The result of this has becomea maintenance-free and wireless product to trailers.

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.
