Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.

In Sweden whenever trains or maintenance workers want access to the railway system, their requests of usage and movements are being supervised, granted and handled by train dispatchers. The profession holds a key role in making the complex railway system work in terms of efficiency, safety and delivering on-time arrivals. This master thesis, delegated by the Swedish Transport Administration, has been carried out at the Division of Human Computer Interaction at Uppsala University and at the train traffic control center in Gävle. The aim has been to map what information the train dispatchers use in order to make safety-related decisions concerning their working goals. And further to describe and analyze how the train dispatchers, visavi their tools and systems in the work domain, gather necessary information.The result indicates a complex, diverse and spread out setting of different programs, procedures and tools that make satisfactory fulfilment of efficiency, safety and punctuality in relation to the time table hard.

Cloud computing is a new buzzword within the IT-industry, and introduces a whole new way of working with IT. The technique delivers web based services, which results in that the user no longer needs to install an application locally on a computer. Since the application no longer needs to run on a local entity, but in a datacenter located on a service provider, the users no longer need any specific hardware more than a computer with an internet connection. Cloud computing also offers IT-infrastructure and development environments as services, these three service types is better known as cloud services. Through the usage of different types of cloud services, the need for maintenance and hardware is significantly reduced.

Stroke är ett samlingsnamn för hjärninfarkt, hjärnblödning och subarachnoidalblödning och är en av de vanligaste orsakerna till funktionsnedsättning internationellt sett. Insjuknandet i stroke är en plötslig händelse som för med sig stora konsekvenser. Den drabbar individen både fysiskt, psykiskt men även det sociala livet förändras. Livskvalitet är ett begrepp som beskriver individens upplevelser av sin livssituation. Att drabbas av en stroke har visat sig påverka känslan av livskvalitet.

Banking systems in India is quite popular and it needs some more changes to reach all the customers. Lack of the service is main problem in Indian baking system. If the common person wants to open the account, it take?s little bit high cost and banks are not near the people location. Due to the Lack of service, people do not want to be a customer of the bank.

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

This master´s thesis in Library and Information Science examines the experiences of children who read to a dog. The purpose of this thesis is to examine the interactions between the librarian, the readingdog-handler, the child-ren and the dogs and what the benefits from the interactions might be. The aim is also to examine how the child-ren express their literacy during the readingsessions and how to develop the readingsessions at a specific library. The author follows a reading dog project for seven weeks, in collaboration with a specific school and library. Action research was used as a research strategy, and since action research is done on the basis of practice, a coll-laboration with the participating children, the librarian and the readingdog-handler was significant in this study.The theoretical framework concists of theory and concepts from the sociocultural theory developed by Ro-ger Säljö, and human-animal studies with concepts from Donna Haraway.

The contribution of biofuels to the total consumption of energy in Sweden must increase to 49 % in order to meet the goals for the year 2020 set by the European Union. In order to do so, improved information systems are needed to support the business processes within delivery scheduling between customers and suppliers.Enterprise Architecture (EA) is a concept to enable the alignment of Business processes and Information Systems. EA is the framework for the architectures of business, information and applications. With a comprehensive view of the architectures, an Information System aligned with the Business processes can be enabled. The first step in the development of an Information System is documenting the business processes.The goal of this study is to clarify a generic sequence of activities performed within the delivery scheduling process and the information needed to perform the activities.Data for the study was collected through qualitative interviews, first through a meeting with the respondent and after that a following telephone interview with in total 5 suppliers and 6 customers of biofuels.

The resting area is the most important place in the barn for the dairy cow, sometimes called the heart of the free stall system. Inadequate design of the lying area, and lack of or poor quality of bedding materials may reduce the hygiene of the stall. Poor management regarding the cleanliness of the resting area may lead to poor animal hygiene and increased bacterial growth. This in turn will lead to increased risk for environmental mastitis as well as impairing milk quality through contamination with spores. In this literature study the most commonly used bedding materials; straw, sawdust, wood shavings, clean sand, recycled sand, peat and recycled manure solids, are compared to one another with regards to their ability to resist bacterial growth. Effects of adding hydrated lime to bedding materials have also been studied. Most bacteria need humidity and prefer a quite high water activity to be able to grow.

Our purpose with this research is to highlight that there is a scope for increased value creation in the experience room during concerts, and how value-enhancing strategies can be a competitive advantage for different venues. In our investigation of this we have worded the following research question: How is the perceived customer value affected during a concert in the experience room and its physical environment? With the background in this question we have identified three key concepts that we believe are the influence of the total concert experience which are; sensory experiences, interaction and identity. From these concepts we have drafted a number of propositions to test the reality by our empirical data collection. .

En rad förändringar i de kommunala verksamheterna kan hänföras till tankarna kring behovet av ett nytt tänkande och åtgärder för modernisering av offentlig verksamhet, en förändringsvåg som ofta beskrivs med samlingsbegreppet New Public Management (NPM). Offentlig styrning har blivit allt mer lik den privata och med NPM har offentliga verksamheter tagit mer sikte på marknadskrafterna. En konsekvens av detta tänkande är att medborgarnas synpunkter på verksamheten tilldelas en allt större vikt.Klagomålshantering har för många privata företag under en längre tid varit ett naturligt sätt att hantera kundernas synpunkter på verksamheten. I företag som är inne i en satsning på total kvalitet (TQM) betraktas klagomålshantering ofta som ett del- eller följdmoment till dessa ansträngningar. TQM, ett koncept med grunderna i den japanska tillverkningsindustrin, har som centrala ledord att kunden ska stå i centrum, arbeta med processer och basera beslut på fakta.Idag används TQM som ett uttryck för organisationens syn på kvalitet även av många offentliga organisationer.Hur klagomålshantering ska betraktas i den kommunala verksamheten är dock inte självklart.

Mjölkavkastningen har ökat kraftigt de senaste åren och inom mjölkproduktionen eftersträvas högavkastande kor med bra hälsa och som producerar mjölk med hög kvalitet. Ett problem med dagens mjölkproduktion med 12 månaders kalvningsintervall är att korna i genomsnitt producerar mjölk under enbart 2,5 laktation, vilket innebär att de producerar mjölk under mindre än hälften av sin livstid. Dessutom sinläggs de vid en relativt hög produktion och det har rapporterats att med 12-månaders kalvningsintervall finns en del reproduktionsproblem, vilket bland annat har orsakat den korta produktionstiden. Ett sätt att minska problemen skulle vara att förlänga kalvningsintervallet och få laktationen att bli uthålligare. Det finns flera olika mjölkningssystem och mjölkningsrutiner och frågan är om man via system och rutiner kan påverka laktationens uthållighet.

Thinning is the partial removal of trees in a forest stand prior to final harvest. The term can be divided in pre-commercial thinning where little if any volume is removed from the stand and commercial thinning where removals are intended to provide a positive economic result. From a silvicultural point of view, the goal of thinning is to enhance future crop tree quality by removing low-quality stems and providing sufficient space for the accelerated development of retained ones (Huuskonen & Hynynen, 2006). The goals of this study was to see if commercial thinning could positively affect the short and medium term timber supply (MTTS) in the Interior regions of British Columbia (BC), and whether or not Scandinavian forestry practices could be adopted in the BC context. The mountain pine beetle (Dendroctonus ponderosae Hopkins) has created significant forest planning problems in BC. The annual allowable cut (AAC) was raised to capture beetle-killed timber while still merchantable.

This is an investigation of a mobile prefabrication factory´s competitiveness and profitability which also will result in a suggestion for a design of the factory. The mobile prefabrication factory is an idea of a new concept for production which is meant to be used in the manufacture of slab. The main intention with this concept is that by using a fast established prefabrication factory to produce elements near the construction site, thus avoiding transport from the factory to the building site. This means not only an environmental and economic gain, but also that you can avoid risking damage the elements which often occur during transportation. The contractor is owner of the mobile prefabrication factory and can thus avoid long waiting times and cyclicality.

The measuring of logs is important in the sawmills process to the sawn products. The technology of automatic wood measurement is continuance developing. This study has the purpose to see how the different techniques and the routines works of measure frames for determining of wood value and sorting in sawmills. The study is performed as a literature study and a survey. The survey includes some of the Swedish sawmills that produce more than 10 000 cubic meters sawed products per year.
