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.

Development and construction of an electronic Breakout box is the main work for this thesis. The box is a part of a test system for the component Fuel Flow Transmitter and should convert signals to be suitable for a frequency counter. A previously constructed Breakoutbox for this purpose is being old and needed to be recreated. So SAAB Aerotech, Aircraft services, the company for the thesis work wanted to construct a new, more sustainable Breakoutbox adapted to a more modern technology. The signals to the box comes from the transmitter and should be converted to suitable signals for a frequency counter so it can show pulse and time difference between the signals.

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

AbstractThe tests work is about the subject "synergism of steel and concrete."The construction sector is in a strong competition and the different companies in the PrefabMarket has ever tried to develop new design solutions that are efficient and environmentallyfriendly.The purpose of this report is to highlight different aspects of interaction and size up a columndimension and to examine its efficiency and load capacity as Eurocode 3 and Eurocode 4. A sizing chart that describes the relationship between the torque and normal force shouldalso be made of the interaction . .

Drawing on earlier research, and using observations as the method, this study presents a design of a nature playscape for children. Applying outdoor pedagogy to the fundamental structure of a specific location, the study proposes a design of a playscape, over a more obvious design, for instance one based around a quiz walk.The theoretical framework is Gibson?s theory of affordance, and the goal has been to create a "play flow". The study concludes that spatial rhetorics can be an important tool when teaching children about nature..

Self-driving cars are soon to become a reality to the commercial market. A self-driving car does not have a human operator, which enables some interesting characteristics. The main benefits are considered to be:The number of accidents and traffic jams should be reduced.Enhanced comfort.Energy usage could be decreased while capacity could be increased.This study concerns the causes for improved energy efficiency. The reason for improved energy efficiency is mainly because of the variation in terms of acceleration, braking and distance holding are reduced. The vehicles are more intelligent and can work together as a unity.

Denna kvalitativa motivationsstudie utfördes på åtta svenska toppsäljare och utgick i från Vallerands hierarkiska modell om inre och yttre motivation (1997) och även från Czikszentmihalyis teori om flow (1990). Syftet med studien var att ta reda på vilka motivationsfaktorer som förenar toppsäljare. Toppsäljarna intervjuades enskilt genom en semistrukturerad intervjuguide. En tematisk analys utfördes på utskrifterna från intervjuerna och analysen undersöktes utifrån tre huvudkategorier: inre motivation, yttre motivation, och flow. Resultatet visade att toppsäljarna hade en stark inre drivkraft att utvecklas, att nå egna mål och uppnå positiva känslotillstånd av själva utförandet.

Essay in Political Science, C-level, by Camila Alvarez Cea, spring semester 2010. Tutor: Alf Sundin?Reality or a Political Mirage? ? A Study of the Swedish Press Views on the Health Insurance Reform in the USA? The purpose of this essay is partly to examine whether the picture that Swedish press presents of the health insurance reform in the US, which is part of the Patient Protection and Affordable Act bill, will be of crucial importance to the possibilities that the American population has to receive health insurance. The main research question is accordingly: ?Does the picture that Swedish press presents of the health insurance reform in the USA, seem like something that will be of radical importance to the possibilities of the population to receive healthcare?? The purpose is also to examine in which model (demand or market) the opinions of the Swedish press fits. This purpose will be answered by using three specific questions asking whether their opinions differ when it comes to three criterions: organization, financing/resources and delivery systems.

The aim of this Master?s thesis is to investigate the meaning the reading group of the public library has to a number of users. To fulfill the aim the following three questions have been formulated: 1) What do a number of users expect from the reading group of the public library? 2) Which approach/attitude or approaches/attitudes do a number of users have to reading and to talking about reading? 3) How do a number of users experience the ongoing reading group?The research is founded on qualitative interviews with five users that take part in three different reading groups in public libraries. The theories that are used is the theory of three so called strategies - the pragmatic, the traditionalistic, the emancipatory ? and the theory of flow.

AbstractSkanska Sweden has decided to split the organization that earlier handled both large and small projects into two different subsidiaries. A consequence of this is that all construction service handling will from now on be enforced under the name Skanska Direkt AB. The management of Skanska sees this as an opportunity to develop the organization and in the long term achieve higher earnings.   The task which Skanska in connection with the reorganization wanted to be investigated was a proposal on how the organization of work with the insurance work in the future should look like.The organization that is handled is from production manager to professional workers and includes damage handling that has been obtained from insurance companies in the southern and northern parts of Värmland. The purpose with this work is to present a different kind of view to the problem with developing this branch of the company. The main target was to work out a proposal of an organizational plan for the damage handling in Skanska Direkt AB that is possible to apply, less sensitive for dismissals, results in higher earnings, obtains higher customer satisfaction and also a staff stab that develops their skills at their own.The report and work progressed as following:Opening theory study of strategies to obtain the objectives set.Restructuring of existing organization with theories as support.Interviews with the actors involved to verify feasibility of the developed organization plan  Organization chart, the result of work means that some workers at each location shall be responsible for a small group of workers and work independently. They shall manage the process of invoicing and calculate costs at the same time as they work out on the workplace.

Self-driving cars are soon to become a reality to the commercial market. A self-driving car does not have a human operator, which enables some interesting characteristics. The main benefits are considered to be:The number of accidents and traffic jams should be reduced.Enhanced comfort.Energy usage could be decreased while capacity could be increased.This study concerns the causes for improved energy efficiency. The reason for improved energy efficiency is mainly because of the variation in terms of acceleration, braking and distance holding are reduced. The vehicles are more intelligent and can work together as a unity.

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

In Halland, agriculture is the major source of eutrophication of water. In the study, synoptic sampling were performed in the three watercourses Nyrebäcken, Skintan and Vinån all located in the county of Halland. Sampling occurred during the period February to May on three occasions with different flow rates: high, low and base flow. Samples were taken in the mainstream and tributaries with intention to show how big the impact of eutrophication it is in the water and  to assess the impact of the tributariesThe results show that all watercourses are affected by eutrophication. Nyrebäcken has the highest concentrations of nitrogen and phosphorus in the mainstream, then Skintan and last Vinån.

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.
