Mobile devices such as tablets and smartphones are quite common in this day. The author of this thesis wanted to know how common these mobile devices are in the building industry and how they are used and what potential an app could have. The author thus conducted an investigation on this matter, mainly in the form of interviews.Answers given by the interviews were then used as a basis to survey the usage of mobile devices and the usage of different kinds of apps. An investigation of different apps with the potential to be used by professionals in the building industry has been carried through. Apps which manage such things as scanning documents, measuring distances and handle communication.

The accident frequency in the construction industry has shown a downward trend every year but this trend was broken 2010th. It is often lack of precautionary measures within work environment and safety that is the cause of accidents. The big construction companies understand the importance of precautionary measures within work environment and safety, as they spend a lot of money and time on that matter. By examining the work environment and the safety of the small construction companies you can see how they work. The report will presents how these small companies work with work environment and safety, and also how they follow the safety instructions that are available and how they make use of safety equipment.

Female growth, number of eggs and egg growth of Daphnia pulex were studied at four temperatures, 12, 16, 18 and 20°C. I hypothesized that female growth and number of eggs would be lower and the size of the eggs larger in the presence of a predator (kairomones) than in its absence. This effect was expected to be more evident at lower temperatures. I could not find any effect of kairomones on female growth, number of eggs or egg size, although there was a weak tendency for an effect on number of eggs. There was, however, an effect of temperature, regardless of predator treatment (i.

This report describes what wireless local area networks are and the use and configuration of them. These WLAN as they also are called can be used both in new installations and expansion of existing networks. Further on this report reveals security in this area. Security is incredible important in all networks not at least wireless because you don?t have to be in the environment physically to get the information, you only have to be in the coverage area that can be several hundred meters.

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 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.

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.
