Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Electrolux Laundry Systems is the world leader in manufacturing professional laundry equipment.The machines are used in the hotel sector, elderly care, in multifamily houses, laundry bars, and incommercial and institutional laundries.If there is oil or grease left in the clothes after washing may the heat from the dryer cause a chemicalreaction. This reaction may, under certain circumstances cause a fire inside the drum. Competitors toElectrolux has developed its own systems that extinguishes fire inside a tumble dryer and customershave expressed desire to purchase a fire-extinguishing system. Therefore, the project team receivedthe task by Electrolux to develop a fire-extinguishing system that extinguishes a fire in a tumbledryer.The purpose of the project has been to develop a system that both detects and responds to fire in anindustrial tumble dryer to meet the competitors and to satisfy customers' requirements.The goal was to develop a fire-extinguishing system for Electrolux Laundry Systems and develop afully functioning prototype.The project began with information searches on a variety of methods to both detect and extinguish afire. Subsequently, a number of different methods were used to develop a final solution and make aprototype.The result of the project is a fire-extinguishing system that extinguishes a fire inside a dryer.

Seventy-two working horses (they had been ridden with bit and bridle within the last two weeks) were examined in the oral cavity. Findings and status were noted. The horses were randomly chosen among individuals without clinical symptoms from the mouth and gastrointestinal system. The result showed that 93% of the horses had changes in the mucus membranes, 86% in the form of ulcerations. The P2 region was most commonly affected followed by wounds more caudally in the mouth (P3-M3 region).

I USA infördes begreppet informationsoperationer i mitten av 1990-talet och det har sedan dess skett en stor utveckling inom detta fält. Även i den svenska Försvarsmakten har konceptetinformationsoperationer införts och en utveckling och uppbyggnad av förmågor inom detta koncept pågår. Syftet med denna uppsats är att undersöka huruvida konceptet informationsoperationers uppkomst i Försvarsmakten kan utgöra ett exempel på idéspridning. Utgångspunkten är att USA som en av världens ledande försvarsmakter är trendsättare för andra försvarsmakter i västvärlden, däribland den svenska Försvarsmakten. Med utgångspunkt i teorin om idéspridning undersöks om den amerikanska idén om informationsoperationer har spridit sig och snappats upp av Försvarsmakten som sedan översatt idén efter sina egna förutsättningar.

Earlier this year the Swedish migration board gave a part of their responsibility for the separated children to those municipalities that have signed an agreement with them, so that the children can get the best handling of their matters and also to lift the heavy pressure of the Swedish migration board. Our aim in this paper is to see how this division is made and which areas of responsibility they have. We want to see how this process is being handled in relation to these children?s rights, the Convention on the Rights of the Child and the Swedish law. To get the best information possible we used a qualitative method.

Titel: Den kommunalt fängslade mellanchefen: En kvalitativ beskrivning av mellanchefers utövande av ledarskap. Inledning: Kommunal verksamhet är starkt påverkbar av sin omgivning och måste kontinuerligt anpassa sig till denna samtidigt som den strävar efter en förutsägbarhet. Denna komplexa miljö inverkar på mellanchefers möjlighet att utöva sitt personliga ledarskap, och därför ställs det krav på att man som chef är anpassningsbar och medveten om sitt personliga ledarskap.Problemformulering: Hur ser chefer i olika hierarkiska positioner på sin möjlighet att utöva sitt personliga ledarskap?Syfte: Syftet med vårt arbete är att undersöka, beskriva och skapa en förståelse för chefers möjlighet att, på olika hierarkiska nivåer, utöva sitt personliga ledarskap i ett sammanhang påverkat av inre och yttre faktorer.Metod: För att besvara vårt forskningsproblem valde vi att använda oss av en kvalitativ metod. Genom ett hermeneutiskt tolkningssätt och ett abduktivt angreppssätt så analyserade vi de sex semi-strukturerade intervjuer vi utförde.Slutsats: Den slutsats vi drog är att ledarskapsutbildningens utformning och den begränsade rörelsefrihet som ges, resulterar i en konflikt mellan organisationens mål och en chefs möjlighet att utöva sitt personliga ledarskap. .

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.

The main purpose with this study is to make the modified parenting visible in relation to the school over time. How have the views of parenting and support, by the pedagogues and the parents, earlier been interpreted and how is it today? The results of the interviews, which were more like an everyday dialogue, were analyzed through a phenomenological effort with a hermeneutist method interpretation. The theory connection has mainly consisted of relevant terms for this study.I have come to the conclusion that parents today feel that they have an extended responsibility when it comes their own children?s knowledge.

The real estate industry is a sector where the companies generally have a capital structure which is high leveraged. The financing? with the related terms ? is therefore specifically of high importance for the companies in the sector. Traditionally, the way of obtain financing is by borrowing from the bank. Lately, due to new bank regulations, the banks have become more restrictive in their lending which have lead to a growth of other financing alternatives.

The care for the elderly in the municipalities has recently seen the need for a formalized system for quality assurance. Under increasing demands for monetary efficiency while bound by law to retain acceptable standards in health care, there is need for efficient and at the same time quality-assured management. The municipalities often solve this puzzle by introducing systems and standards influenced by theory-clusters such as NPM (New Public Management), TQM (Total Quality Management) or other quality management theories.This essay focuses on how the public administration in the municipalities defines quality and designs and implements system for formalized quality assurance. Our basic view of organizations is institutionalist and our theoretical framework includes theories about quality, NPM and TQM..

Reptiles and birds are animals that many people don?t have much experience of, so it can be difficult to do a proper animal protection assessment of these animals. It?s hard to determine if these animals is skinny, fat or in good shape, to do that it demands handling of the animal and not many inspectors that works with animal protection have experience of handling reptiles and birds. To see if a reptile or a bird is ill is difficult, when the bird or reptile looking sick it?s often too late to do something. www.blocket.se is a sell and buy page on the internet there many animals switch owner.

Arbetslivet förändras och detta leder till förändringar av organisering och struktur inom organisationer. För att möta behov av flexibilitet, effektivitet och konkurrenskraft har nya sätt att organisera resulterat i nya ramar och strukturer för arbete med personalfrågor.  Dessa nya sätt att organisera har lett fram till nya roller och ansvarsfördelningar.I denna studie var syftet att skapa förståelse för hur HR- funktionens utformning påverkar chefers arbetssituation. Studien undersökte chefers upplevelser av HR-stödet i relation till arbetssituationen inom en organisation där HR-stödet bygger på ett service center, en expertenhet och HR business partners ute i verksamheten. Uppsatsen bygger på tio kvalitativa intervjuer med HR-medarbetare och chefer på Trafikverket.Studien visar att cheferna upplever ett tillfredställande HR-stöd från expertenheten och HR business partners. Samordningsproblem inom HR-funktionen ger dock effekter för både chefer och HR-medarbetare inom organisationen.

Brands are the instruments corporates use to create and communicate brands reputation. Within the different industries for consumer products intangible assets such as brands are known to have great importance for corporate prosperities. When consumers experiences a specific brand symbolizes best possible value for money, the corporate behind it has managed to create a unique competitive advantage that should be to its full potential. Strong brands can pose the difference between winning or loosing on the market. Due to this brands should be considered as cost-effective instruments since they help create financial advantages such as consumer loyalty.

 The aim and scope of this study is to describe the coordination of joint efforts concerning chemicals and hazardous substances in the Baltic Sea region, between the Swedish Chemicals Agency (KemI) and the land-based pollution group of the Helsinki Commission (HELCOM LAND). Based on the description of the coordination, the second aim is to discuss the consequences for the Swedish Chemicals Agency in its policy shaping work towards a nontoxic environment. A qualitative and descriptive case study method is used for this purpose. Theories of coordination and achievement-inducing criteria for environmental goals are applied to the case. Components and related processes of coordination are applied to the descriptive part of the study, whilst the achievement-inducing criteria are applied in the discussion.

Syftet med denna studie har varit att besvara frågan hur ett medarbetarsamtal upplevs av den anställde. Att ställa frågan ?är det värt det? innebär att se om den anställde upplever att medarbetarsamtalet är en givande kommunikationsform eller om den anställde känner det som ett otillfredsställande samtal.Uppgifterna och svaren är inhämtade genom individuella intervjuer genomförda med deltagare i ett arbetslag inom den privata vårdsektorn.Studien har en kvalitativ ansats och baseras på semistrukturerade intervjuer.Studien har visat att medarbetarsamtalet inte upplevs som tillfredställande när det gäller kommunikationen med och till överordnad. Det har framkommit att anställda föredrar kommunikation inom hela arbetsgruppen via öppnare samtal mellan samtliga anställda. Vad studien också visar är att de anställda upplever sin chef och kontakten med chefen på olika sätt beroende på situation och kontext.Vi har utgått ifrån teorier kring institutionaliserade samtal, emotionellt arbete och tvång samt sociala band för att behandla och analysera informanternas upplevelse av medarbetarsamtalet.Den anställdes emotionella arbete påverkas av rollen den anställda upplever som passande för yrket samt att relationen till chefen påverkas av status och ställning. .
