Overall Equipment Effectiveness (OEE) : Problem och framgångsfaktorer vid mätning av utrustnings effektivitet med OEE i små företag
En hård konkurrens bland dagens produktionsföretag på en global marknad ställer kravpå dessa att vara effektiva i sina processer för att överleva. Särskilt små företag, sominte har ett stort företags ekonomiska muskler och möjlighet att investera i nyutrustning, måste vara innovativa och kunna utnyttja befintliga resurser maximalt.Overall Equipment Effectiveness (OEE) är ett nyckeltal som mäter ett företagsutrustningseffektivitet. Genom att använda OEE kan ett företag uppmärksamma var detfinns förluster i produktionsprocesserna och därefter åtgärda dessa.Den här rapporten ämnar reda ut i vilken utsträckning små verkstadsföretag i Sverigeanvänder OEE idag. Teorin pekar på att stora effektivitetsförbättringar är möjligagenom användning av OEE i stora företag, dock finns endast lite litteratur sombeskriver användningen av OEE i mindre företag. Syftet med rapporten är därför att tareda på vilken potential det finns för små företag att använda sig av nyckeltalet OEE samt att identifiera specifika framgångsfaktorer för dessa.Genom intervjuer med små verkstadsföretag och konsulter väl insatta i OEE, harproblem och framgångsfaktorer identifierats.
Modellbaserad estimering av lastande moment ihybrida anläggningsmaskiner
SammanfattningDetta projekt har genomförts i samarbete med Volvo Construction Equipment (VCE), enav de ledande tillverkarna av anläggningsmaskiner. Syftet med detta projekt var attundersöka om huruvida det är möjligt att estimera lastande moment på motorn i enhybridhjullastare som orsakas av dem sekundära hydrauliska pumpar som är anslutnatill den, detta med hjälp av dem tillgängliga sensorer som är monterade på maskinen.Der estimerade momentet skulle sedan användas för att förbättra motornsvarvtalsregulator och för att för ge en bättre arbetspunktreferens för motorn som skötsav ett energi manegement system.Projektet kan delas upp i tre delar. Den första delen var att ta fram en matematiskmodell som beskriver sambandet mellan pumpens lastande moment och demtillgängliga sensorn signaler. Andra delen består av att välja och implementera enlämplig skattningsmetod för att estimera det lastande moment. Och slutligen enimplementerings del där man tillämpar det skattade momentet för att förbättra motornshastighetsreglering.En estimeringsalgoritm har utvecklats och testats i hjullastaren som har visat enförbättring av motorns varvtalsreglering.

Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry
Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land
management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC)
compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on
crops during drought.
The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to
study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.
Rengöring på restauranger : Kontroll och utvärdering av olika rengöringsmetoder på restauranger i Södra Roslagen.
Control and comparison of various cleaning methods on restaurants in Södra RoslagenThe purpose of this report is to find out and analyze the efficiency of cleaning methods in restaurant kitchens. The investigation was carried out through unannounced inspections at 89 restaurants in Södra Roslagen (municipality of Danderyd, Täby and Vaxholm). ATP-measuring was done on a plate, a knife, a bench surface and a cutting board. The ATP-method measured the amount of food residue on equipment and working surfaces after cleaning, with a luminometer and swabs. Restaurant staffs were asked to describe in detail how and when the last cleaning was carried out on the surface.
Färgstyrning av kontorsutrustning
Color management has become more common now than ever in the graphic trade. Calibration andcharcterization are words that are mentioned very often when it comes to controlling colors andwhen you want a printed picture to look the same as an original photograph. The problem is thatthere are not so many people that has the knowlegde about this subject. Even if a printer supportscolor management it is not sure that the result is going to be satisfied and that a printed picture isgoing to look the same as the original.The printers which were used were Hp DeskJet 970 Cxi, Xerox Docu Color 12 and AgfaChromapress 50i. The theory of color, colour management and the equipment which were usedare described in the first stage.
Ansvarsförhållande kring förebyggande materielvård på förbandsnivå inom armén
The change in course recently taken by the Swedish Armed Forces results in an increased use of equipment, and thereby increased requirements of preventive maintenance. This paper aims to examine the current responsibilities for preventive maintenance in an army unit. The intended effect of this examination is to disclose possible flaws, and to help make routines for preventive maintenance more effective.The questions asked in this paper are;Who, in an army unit, is responsible for the routine maintenance?When is this responsibility valid?What demands does the technical service have on responsibilities for the routine maintenance?How are these demands met?How ought to be responsible for the routine maintenance?To answer these questions the author has chosen to use a descriptive method to show the current facts. A theorizing method is chosen to, from described facts, clarify the demands of the technical service on routine maintenance.
Bygga hus i traditionell härjedalsstil
The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Mikroalger för hållbar energiproduktion - Chlorella vulgaris i en kretsloppsanpassad alg-biogasprocess
Odling av mikroalger för framställning av biogas är ett relativt outforskat område. Den forskning som hittills utförts har påvisat lovande resultat tack vare möjligheten att utnyttja resurser som idag går till spillo, eller till och med utgör miljöproblem; mikroalgerna kan rena både näringsrikt vatten (exv. avloppsvatten) och koldioxidutsläpp (rökgaser från industrin) då de tar upp föreningar innehållande kväve, fosfor och kol från dessa källor. Den producerade biogasen kan ersätta fossila bränslen. Dessutom skapas en rötrest som kan återföras till odlingsmarker vilket sluter näringskretsloppet.
Kundanpassad tjänsteutveckling och förändrade relationer inom den försvarsindustriella sfären
The aim of this thesis is to describe the customer?s attitudes toward the contracting for availability, i.e., which factors are from the customer?s perspective necessary for the fulfilment of a supplier-customer agreement? Furthermore, the objective is to describe and analyse a supplier-customer relation in the Defence Industrial sphere.The present study has been carried out as a case study using an abductive approach. The thesis is based on a practical problem, i.e. which factors will be important to the customer when a contractor in the Defence Industry wants to increase its commitment of service, and how will their relationship change? The thesis is above all focused on generating knowledge that can lead to rapid and concrete measures and that can be used in the analysis of an increased industrial commitment but also as a case study of a problem of a more general nature in the Defence Industry.
