We have left the industrial society, and instead, we live in a post-industrial knowledge and information society. It is often said that industrial production has disappeared or that it has changed greatly. This means that fewer are employed in the manufacturing sector while the service sector is increasing, resulting in that the boundaries between production and administration decreases. The production goes from mass production to more flexible and specialized solutions. This puts greater demands on the logistics chain that continually need to work to meet customer requirements.

A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.

 This report deals with thecollaborative project between FagrellProdukt Utveckling AB and studentsfrom the Faculty of Science andTechnology at Uppsala University. Theoverall objective of the project wasin addition to developing students'abilities, to help Fagrell withverification and development ofFagrells prototype, Fundamental flowreactor, for flow chemistry.

AbstractPurpose ? The purpose of this study is to investigate possible reasons for long lead-time in a customer driven production, and how the lead-time can be reduced. To fulfil the purpose the study has been broken down into two questions.1. Whichfactorsaffectthelead-timeinacustomer-drivenproduction?2.

The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.

Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

Findus Sverige AB, referred to asFindus from now on, harvests peas during a period ofaround 50 days during the summer. The harvest generates about 30 000 tonnes of peas which gives around 40 000 pallets to distribute to the warehouses which Findus uses for final storage. Three hours after the peas are picked in the fields, they have to be frozen to keep their good taste and quality. Because of this the pallets are marked with a preliminary label with quality classification of the content. The Findus quality department then has one day to determine the correct quality of each pallet.

Saab Training Systems (STS) in Huskvarna is manufacturing material for educationalpurposes to armies worldwide. They are now implementing parts of the Lean productionconcept in their organisation.One part of the work with Lean production is to eliminate waste. To be able to identify waste,value stream mapping is a good tool and also what we used in our thesis. To gain a betterefficiency in the production of Personnel Detector Device (PDD) flow was one of our goals.The PDD is a harness used during battle training which registers if the user is being hit by itsenemy.Our work with the thesis started up with a short education in Lean production and in valuestream mapping (VSM). The work proceeded with a VSM of the Production flow of the PDD,interviews were made and studies of literature were done to gain greater knowledge of thesubject and solve the task.The VSM resulted in five areas which were followed up out of those six we identified.

Nowdays an efficient production is critical to achieve for companies competing on the market for steel cutting tools. One of such companies is Halmstad based Tooling Support Halmstad AB that manufactures threading-taps, threading-dies and parting off tools, towards a centralized warehouse in Schiedam, Holland. The large amount of different products, approximately 2500 is a big contributor to the problem along with a new order system that creates a demand of low setup times. Previously the company was forwarded orders through quarter based prognoses which enabled planning of the production over a longer time span. Currently the newer order system ZENIT is in use and the company thereby gets their orders weekly.

From the customer?s perspective the only reason for a firm to exist is the value it creates. However, a problem within manufacturing companies is that of the total lead time, only a small part can be considered as value adding. It has further been discovered that when working with improvements businesses often sub-optimizes single processes instead of considering what benefits the entire company. Thus, when improving processes and activities it is important to have knowledge about and understand which factors that affect how the flow can be designed.Several studies have been performed with a wide perspective on process flows in order to obtain a more resource-efficient and value added flow.

Detta  examensarbete  undersöker  skillnaden  i  tre  olika  nybörjargruppers  upplevda flow  då  de  spelat  Magicka  (2011)  med  motståndarantal  som  den  enda  skiljande variabeln.   Undersökningen   baseras   bland   annat   på   Csikszentmihalyis   (1990) flowteori och Caillois (2001) teori om att tävlande slutar vara roligt då det  urartar i kaos.  Syftet  med  examensarbetet  har  varit  att  hitta  när  mest  flow  uppstår  då nybörjare på Magicka (2011) spelar mot  en viss motståndartyp, samt om  detta flow bryts  när  för  många  motståndare  introduceras.  Undersökningen  har  visat  att  nio motståndare har resulterat i betydligt mer flow än tre, medan skillnaden mellan nio motståndare  och  18  har  varit  obetydlig.  Examensarbetet  har  dock  inte  lyckats kvantifiera  var  flow  övergår  till  kaos  med  den  testgrupp  och  motståndartyp  som använts.  Framtida  forskning  skulle  exempelvis  kunna  undersöka  på  vilket  sätt  ett varierande  motståndarantal  skulle  påverka  flow  för  en  mer  erfaren  testgrupp  som spelar mot andra motståndartyper..

Starting out as a minor form of amusement, the game industry has become one of the most lucrative andsuccessful in the entertainment business competing against giants such as television, movies and music.As the internal competition within the developer community grows companies work hard at discoveringnew ways to attract and keep customers. By having a playcentric approach focusing on user experiencethey hope to achieve that goal. This thesis describes the process of designing a game with focus on theplayer. We apply the concept of flow on game development and investigate through research throughdesign if we are able to create a game that keeps the player in flow.Play tests showed several elements such as control issues and too difficult challenges early in the game,affecting the possibility for players to experience flow while playing. These negative factors came to becalled flowleakers.

This report deals with the performance of a batch flow treatment of landfillleachate compared with a continuous flow system. The parameters in focus were total Kjeldahl nitrogen (TKN), BOD5 and COD. The pilot-scale experiment used eight barrels with a volume of 150 liters. Each barrel was constructed differently concerning its flow, its bed material grain size and its presence of plants or not. Four of the barrels worked in batch mode, thus four in continuous flow mode.

Syftet med föreliggande studie var att undersöka hur ryttare upplever Flow, och vidare även hur ryttare upplever samspelet inom ekipaget vid Flow. Studien inkluderade 10 kvinnliga informanter (M = 18.7, SD = 1.48) med tävlingserfarenhet som sträcker sig från ingen alls till internationell nivå (Hoppning= 4, Dressyr = 3, Fälttävlan = 2, Ingen tävling = 1). En semi-strukturerad intervjuguide utvecklades utifrån Csikszentmihalyi's holistiska perspektiv på de nio dimensionerna av Flow (Jackson & Csikszentmihalyi, 1999), och data analyserades kvalitativt genom en innehållsanalys. Resultatet visade både att ryttares upplevelse av Flow stämmer väl överens med andra idrottsutövares upplevelse (Swann, Keegan, Piggott och Crust, 2012), och bekräftar tidigare tolkningar av att ridsporten skiljer sig från de flesta andra idrotter genom att utfallet till stor del är beroende av interaktionen och samarbetet mellan häst och ryttare (Beauchamp & Whinton, 2005). Vidare visar resultatet även att samspelet mellan häst och ryttare är en viktig och oersättlig del i upplevelsen av Flow..
