The effects of the deregulation of the electricity market 1996 in Sweden on short-term hydropower regulation are unknown. This report investigates patterns in subdaily regulation in the Ångerman River Basin during the period 1993-2011. Differences in subdaily flows and zero flow events between the periods 1993-1995 and 1996-2011 were studied by analyzing hourly data from 8 regulated and 8 unregulated locations with four subdaily flow variation indices. No correlations between the market deregulation and the regulation intensity in the Ångerman River basin were detected. The number of days natural ranges of variability were exceeded and the magnitude of subdaily variation were significantly higher at regulated locations.

Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

Syftet med studien var att undersöka sambanden mellan människors motivation till motion, hur de psykologiska behoven kan tillfredsställas samt hur målsättningar och självbestämmande motivationsprofil påverkar motionsbeteenden. Undersökningsdeltagarna i studien var 1100 motionärer (m = 45 år) som var medlemmar i en viktminskningsorganisation. Insamlingen av data skedde i form av en webbaserad enkätundersökning med mätinstrumenten Godin Leisure Time Exercise Questionnaire, The Behavioral Regulation in Exercise Questionnaire-2, The Basic Psychological Needs in Exercise Scale och Goal Content for Exercise Questionnaire. Resultatet visade i stort att en inre reglerad motivationsprofil samt inre målsättningar har ett positivt samband med tillfredsställelse av både de psykologiska behoven och ansträngande träningssnivå. Vidare visade resultatet att inre målsättningar har ett positivt samband med en självbestämmande motivationsprofil.

Denna rapport syftar i att undersöka och jämföra två förenklade motion capturesystem. Det ena systemet innefattar två kameror, och det andra systemet innefattar endjupseende kamera. Problematiken med båda systemen är deras begränsade synfält.Om skådespelaren står riktad mot en kamera så kan den kameran inte se en arm somförs bakom ryggen.Min metod för att göra undersökningen var att filma ett antal olika typer av rörelsermed båda systemen och sedan utvärdera och jämföra den data som systemengenererade, dels genom att testa att applicera den på en 3D-karaktär, och dels genomatt se hur pass bra ofullständig data kunde repareras. Vissa rörelser filmades fleragånger, i olika riktningar. Undersökningen har resulterat i olika slutsatser om de bådasystemen.Att använda två kameror innebar en väldigt tidskrävande process i jämförelse medden djupseende kameran, och skådespelaren var begränsad till att stå riktad mer ellermindre mot kamerorna.

Syfte: Syftet med denna studie är att undersöka de skäl som motiverar äldre människor att motionera och att undersöka hur tillgången till idrottsanläggningar påverkar deras motivation till motion. Metod: Tio äldre människor (60-72 år) intervjuades med semistrukturerade intervjuer. Resultat: Resultaten av intervjuanalysen bidrog till att identifiera flera huvudteman som skäl till att motionera. Dessa teman är: Fysiskt välbefinnande, Psykiskt välbefinnande, Socialt tillhörighet, Synliga resultat och Ändrade livsförhållanden. Resultaten visade också att närheten till idrottsanläggningar är av stor betydelse för äldres motivation till motion. Slutsats: Sammanfattningsvis tycks äldre människors motivation till motion vara knuten till deras känslor inför dem själva, de positiva effekter motionen hade på deras hälsa och andra aspekter av deras liv. Studiens resultat bidrar med förslag till åtgärder som kan vara viktiga att tillämpas som motivationsfaktorer. Dessa förslag kan hjälpa att motivera äldre människor att motionera..

This examination work is performed at the institution of industrial economy and production at Jonkoping technical university, for JELD-WEN Door Solutions plant in Forserum.Today the focus in the company is on to reduce their inventories binding of capitals as well as inventory of products and that includes to get a good control of the supply and handling of material which is of great importance.JELD-WEN Door Solutions is one of the worlds leading producers of windows and doors and the head-office is located in Oregon, USA.A great number of wooden doors are manufactured by the company in varying of constructions, classifications and performance.The production of the plant in Forserum has a project- and customer focus manufacturing where only internal doors are produced. The overall market they are concentrated on is to different institution such as schools, hospitals etc.The purpose of this work is to investigate possibilities to improvement of material- and production control at JELD-WEN. The report will handle the master production schedule to and from the production divisions within manufacturing industry. Focus will be on the way for information- and material flows from arrival, transport within the company and further on to customers.Further a map of the flow was performed which gave a clearer picture of the connection between the flow of information- and material for the manufacturing process. On the basis of the mapping of the flow, the group discovered that the flow of material had some improvement potential.

Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.

Diabetes utgör idag ett växande globalt folkhälsoproblem. Antalet diabetiker beräknas vara 360 miljoner fram till år 2030 (WHO, 2005). Utvecklingen från ett traditionellt liv till en modern livsstil med stress, ökat födointag och mindre motion är några av nyckelfaktorerna i utvecklingen av diabetes typ 2. Sekundär preventiva åtgärder vid diabetes typ 2 är en hälsosam kost i kombination med motion, för att förebygga utvecklingen av komplikationer relaterade till sjukdomen. Syftet med studien var att undersöka vilka sekundära preventiva insatser som finns, för att få patienter med diabetes typ 2 att uppnå god metabol kontroll med fokus på kost och motion samt hur sjuksköterskan kan utnyttja detta i sitt omvårdnadsarbete.

The dissertation were performed on SP, Technical Institute of Sweden. The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal. One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow. Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible. The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics. For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.

Lame dogs are a common group of patients for the practicing veterinarian. In the literature it is described how a clinical examination can be performed, based on general clinical-, orthopedic- and neurological examination, and visual evaluation of the dog when standing and during motion. For research, objective gait analysis systems are also used to study clinically healthy and lame dogs during motion. The aim of this degree project was to compare objective kinematic gait analysis with a visual evaluation of dogs with different types of lameness. The project was a pilot study to show if objective gait analysis could be used as a support for the visual examination. Ten lame dogs of different breeds and with different diagnoses were included in the study. They were all patients at the University Animal hospital, Uppsala.

Human Computer Interaction (HCI) handlar om att utveckla produkter med god användbarhet. Med användbarhet menas att system ska vara lätta att använda och lära. Jakob Nielsen är en av förgrundsfigurerna när det gäller riktlinjer för hur detta ska uppnås. Han har utvecklat tio kriterier som kan användas för att ett så bra system som möjligt ska kunna utvecklas.På senare år har forskare börjat se till, inte bara tekniska aspekter utan även till de känslor som användaren kan tänkas uppleva under det att denna interagerar med en webbsida. Ett flertal forskare har utvecklat teorier kring begreppet Flow.

This report is the result of a thesis carried out at the Department of Innovation, Design and Technology (IDT), at Mälardalen University on behalf of ABB AB Machines.The year was 1988 when ASEA and Brown Boveri formed a joint venture under the name ABB (Asea Brown Boveri).We perform our thesis at the division Discrete Automation and Motion where they primarily develops, manufactures and sells synchronous and asynchronous AC motors and generators.The main purpose of this thesis was initially to write a general packaging instruction, but the priority changed to develop more specific packaging instructions for Rotors, Stator gables, Bearing support and Outer Cover (plates) instead.The work started off to deal with a problem about that the staff had to start its work to grind away rust on the stator gables due to those stored outdoors. The result was mainly an investment in a new gable rack so that the material can be stored inside, as well as a packing instruction as it was originally intended.The problem on the bearing supports were that the staff thought it was demanding and difficult to clean them from the rustproofing they were greased in. If it is not possible to remove all rust protection it can cause the paint to not attach properly. After having compared with similar articles a test were done to order a pair of bearing supports without corrosion inhibitor, which gave good results. This initiative also set in motion a process to do the same for more different items.For special pallet, a survey were made of the process with two different VSM and a calculation of how much ABB would earn at ordering more special pallets than getting the material delivered on the A-pallets.
