This thesis is   focused on identifying and documenting all   electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which devices / elements   are programmed. For further notification, I am not   responsible for the programming of the devices in LabVIEW   which I have only used as a tool in my work. The plant   for production of biogas consists of four reactors   of which the third reactor (Lakbädden)   is connected to another reactor (UASB)   where they cooperate with each other.   The reactors are used for producing   biogas in the form of methane gas.The reactors I and II are   connected to, various electrical devices as, flow meters, temperature   sensors, frequency converter and   more.

The aim of this study was to establish knowledge about the most suitable substrate for cultivating different kinds of anaerobic beer spoilage bacteria in the brewing industry. During the study, two other aspects were investigated; if the sample volume affects the results and which anaerobic beer spoilage bacteria are present in the micro flora at the brewery. The method used was standard cultivation with four different substrates; Universal Beer Agar, Nachweismedium Bierschädliche Bakterien, Raka Ray and VLB S7-S. During the identification of bacteria in the micro flora, a method using PCR was used. None of the substrates showed a significant advantage over the others.

The aim of this report has been to investigate the use of electricity energy before and after a conversion of foodservice. The ambition was also to highlight the food safety and the retention of nutrients in relation to the conversion. The methods being used were qualitative interviews, case studies, study visits and literature. The equipment and the use of energy was the same in 2008 as in 2011 for hot-holding of the tested component, sauce with ham. The chilled system used more than three times the energy and cost for one portion than one portion in the hot-hold system.

Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.

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.

The aim of this study was to analyze the transtextual relationship between Hjalmar Söderberg's Jahves eld (The Fire of Yahweh, 1918) and the Book of Exodus. A limitation was set to just focus on the theme regarding the horned face of Moses, which Söderberg extensively discussed in his book, both through narrative and commentary. The methodological and theoretical approach could best be described as a qualitative text analysis where Gérard Genette's model of five types of transtextual relationships (intertextuality, paratextuality, metatextuality, architextuality and hypertextuality) was used in order to systematically classify the various relationships and in a thorough way relate the texts to each other.The analysis shows that the transtextual relationships are many and varied, and some appears to be more relevant to the study than others. Due to the composition of Jahves eld, its first part (?I österland, i fjärran tid?, most easily described as a paraphrase and pastiche of the Book of Exodus) can be identified as a hypertext to the Book of Exodus, while the second part (?Markels försvar?) is rather a metatext to both the first part and the Book of Exodus.

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.

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.

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.

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.

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.
