A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Syftet med studien är att bidra till kunskap och förståelse kring fenomenet gamification. Denna kartläggning bidrar till att klargöra för- och nackdelar, möjligheter och risker samt eventuella fallgropar med gamification. Om en organisation är medveten om dessa aspekter kring fenomenet minskar riskerna för att någonting ska gå fel, vilket potentiellt skulle kunna bli kostsamt.Studien vilar på en teoretisk referensram hämtad från såväl managmenent- som psykologiforskningen. Förväntansteorin, self determination theory, flow, McGregors Teori X och Y, principal-agentteorin är några av de teorier som används för analysen av gamification.Då det handlar om en kartläggning kring ett relativt nytt fenomen behandlas flera exempel på gamification hämtade från företag som verkar inom branschen. En intervju med speldesignern Henrik Englund finns också med, samt en fallstudie kring polismyndighetens omskrivna användning av spelelement.

Uppsatsens huvudsakliga syfte är att utforska och kartlägga begreppet gamification. Syftet operationaliseras i tre frågeställningar. Vad finns det för likheter respektive skillnader i synen på Gamification mellan ett antal yrkesverksamma inom Gamification? Hur ser yrkesverksamma med olika bakgrunder inom psykologi, pedagogik och marknadsföring på framtiden för Gamification och dess användningsområde? Vilka för- och nackdelar kan finnas med Gamification? Uppsatsen teoretiska utgångspunkter omfattar de psykologiska krafterna bakom spel som flow och motivation, teorier om det praktiska användandet av gamification och teorier om Generation Y. För att samla empiri har kvalitativ metod använts i form av semistrukturerade explorativa intervjuer där yrkesverksamma inom gamification har intervjuats.

Prosthetic leg can give a negative psychological effect to the user, which ends up in decreased self-esteem and that the user hides his handicap. xCover gives a more natural volume and a cool look. xCover changes the look of the prosthetic leg C-leg. The product is constructed by us, Patrik Svensson and Magnus Zetterqvist, for Christoffer Lindhe at Lindhextend AB. Christoffer has hired Martin Bergman at Smedjan 17 to make the design.

This is a report written for an examination project C-level, on the subject of energy. The examination project is a product of the FVB Sweden AB (district heating bureau). It started with a meeting with Stefan Jonsson FVB Sweden AB, were he explained the content of the project, and from this a presentation of the problem was made. The problem that needed to be solved was how they could control the valves in the system to provide heating to everyone in the system. The valves are often oversized so the pump in the heating plant would have to be enormous to be able to provide enough flow to be sufficient, if everyone in the system had there valves fully opened. I came up with two solutions to the problem, one was a wireless network that could keep track of the valves and the other solution was an extra sensor that was placed on the radiator.

Introduction: Urinary retention is a common postoperative complication associated with bladder distension. Permanent damage to the bladder affects the patient?s quality of life and may lead to a lifelong inability to empty the bladder and needs of self-catheterization with the risk of urinary tract infection. Bladder distension was classified as the fourth largest health care related injury in Sweden in 2013. Bladder distension may occur before the operation starts and is more common among orthopedic patients.

This report is the result of an investigation of the possibility to use RFID-technology in a producing company. The investigation is focused on a flow between the company?s producing subsidiary company in Lithuania and its main facility in Sweden.RFID is the abbreviation for radiofrequency identification. The RFID-technology forms the base of a system with wireless information transmission between an object to which a transponder, also called tag, has been attached and a reader. The information is transmitted by radio waves and the system is equipped with software that can digitalise the radio waves.

Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

Syftet med denna undersökning är att ta reda på till vilken grad olika teorier påverkar hur webbsidor uppfattas. Detta för att kunna utveckla mer tilltalande webbsidor. Vi valde att undersöka sex webbsidor: Aftonbladet, Nerikes Allehanda (NA), Dagens Nyheter (DN), IKEA, Hennes & Mauritz (H&M) och NetOnNet.Undersökningen är uppdelad i tre delar: en enkätundersökning, en expertutvärdering och en jämförelseanalys. Enkäten skickades ut till studenter vid Örebro Universitet via studentmailen och resultatet har sedan sammanställts i ett antal frekvenstabeller. Efter detta utfördes expertutvärderingarna utifrån litteraturstudien.

At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.

By exposing their products in blogs, companies have the opportunity to reach out to hundreds of thousands of consumers daily. Instead of using conventional Internet advertising such as banners and ads, some companies chose to make use of product placement in blogs. By choosing to expose their products in blogs, companies use a medium that blog readers are familiar with and can relate to, and can thereby solicit customers for their products and brands.We will examine whether product placements in fashion blogs are an effective way for businesses to market themselves and their products. We measure this efficiency, by keeping a record of the sales of ten product placed garment and accessories that we have selected from four of the largest blogs in Sweden. The stores we examine sales of product placed goods in are volume brand stores such as Zara and H&M etcetera.

The emergency medical care in Sweden has been under persistent debate, due to factors such as long waiting hours, inefficient patient flow, and understaffed departments. In an effort to meet the critique and with a willingness to improve the problems, an increasing amount of emergency clinics are adopting theories and models within Lean. Positive outcomes are evident, there has been some criticism directed towards Lean. Among these is the argument that in order for Lean to be successful it needs to be used within standardized and foreseeable processes, and that it therefore only is applicable to those kind of processes found within industrial production. This prompted the question of whether Lean was a suitable strategy within emergency medical care, considering the large variation of patients and non-foreseeable processes that in fact share little resemblance to that of industrial production.
