I detta arbete har studerats hur flödet i en flerstegs- bearbetningsprocess påverkas av stokastiska fluktuationer och störningar i de enskilda processtegen. Mera bestämt har analys utförts av hur de stokastiska variationerna i operationstiderna kan och bör modelleras vid simuleringsstudier. Även hur påverkan av valet av sådana stokastiska modeller kan tänkas ha på processen i sin helhet, till exempel avseende total genomloppstid.Examensarbetet syftar till att undersöka hur val av fördelning på parametern operationstid, påverkar resultatfaktorn genomloppstid vid flödessimuleringar. För att finna svar på denna påverkan har en fallstudie utförts, med utgångspunkt av indata från en produkt som tillverkas på Volvo Aero. Denna produkt genomgår en tillverkningssekvens innehållande 18 stycken bearbetningsoperationer innefattande tre olika processtyper (automatisk, halvautomatisk och manuell).

Background: The fierce competetivness that characterize todays market force the companies to differentiate their offerings to a greater extent. The customers do no longer choose their supplier on the attributes of the products alone. Their purchase decisions also depend on the relationship the customers have with their supplier. With new customer channels like the Internet and advanced computer systems companies can increase the value for their customers through a better understanding of the customers needs and preferences. In this way companies can create longterm relationships with their customers.

This thesis investigates how different Linux-distributions installation interface relate to the ISO 9241 standard, parts 12 and 13, and how they relate to the installation interface of Windows XP, with the hypothesis: "There is a Linux-distribution whose installation interface according to applicable HCIrecommendations is equivalent to that of Windows XP." With the checklists provided by ISO 9241 an empirical study has been made, and so comparable measurements of how well the Linux-distributions and Windows XP follows the recommendations of the standard was obtained. By comparing the results from the tests similarities and differences between the installation interfaces can be deducted. As the result and the conclusion shows there are Linux-distributions whose installation interface, according to the applicable HCI-recommendations, are equivalent to that of Windows XP..

Distribution av temperaturkänsliga livsmedel går ut på att lagra, hantera och transportera varor till så låg kostnad som möjligt med bibehållande av så stor del som möjligt av ursprunglig kvalitet och hållbarhet. För att klara detta krävs att alla aktiviteter sker under temperaturkontrollerade former, vilket benämns kylkedja.Denna rapport behandlar de aktiviteter som sker i flödet från grossist till detaljist, restaurang och storhushåll samt de aktiviteter som dessa aktörer ansvarar för. Målet med rapporten är att redogöra för hur dagens distributionssystem fungerar för kylda och frysta livsmedel i detta flöde, med särskild inriktning på temperaturhållning och hållbarhet. Kontroller, kvalitet, svinn, reklamationer och problem är områden som studerats särskilt.Väldigt få av de intervjuade aktörerna inom livsmedelsbranschen anser att det är något problem med temperaturhållningen. Intervjuer med myndigheter och studier av rapporter och resultat från dessa ger dock en helt annan bild.

In the present case, the conception of policy hitchhiking gets evaluated in terms of its implications for democracy. This task is executed through the accomplishment of a case study of the use of social- and environmental clauses in the Swedish competitive tendering.A useful definition of policy hitchhiking, including different types of actors, is created.Through the defining of democracy and policy hitchhiking, the author comes to the conclusion that policy hitchhiking in some respects does meet democracy values.The thesis? result can in some sense be regarded as a contribution to the pursuit of knowledge of how power is distributed in the society and how the current distribution can be explained and understood..

The social media arena is rapidly growing and more and moreorganisations take part in the daily ongoing conversations indifferent social media channels. Conversations are being heldacross borders on every available topic and ratings and reviews ofconsumer products and services is one of them. This focus onglobalisation is also the reality of the hospitality- and tourismindustry. Their customers travel across borders and are eager,given the opportunity, to share their experiences with each other.As organisations within the hospitality- and tourism industry meetthese demands in terms of providing technological infrastructurefor information sharing and involve themselves in theseconversations there are some issues that need to be addressed.What does the logic of social media look like? How iscommunicating in social media any different from traditionalmarket communication? And how can hospitality- and tourismorganisations adapt their communication to fit into the logic ofsocial media?To conclude how organisations within the hospitality- and tourismindustry can benefit from the use of social media, I haveinterviewed representatives from a number of organisations andstudied their communication.

Fieldstudys on 22 farms (23 silos) to study relationships between the actual particle size of the maize silage and the theoretical length of cut. The measure of theoretical length of cut were stated by the farmers and not measured by us. Particle size of maize silage was determined using the New Penn State Forage Particle Separator. SLU Skara made a special sieve for us, that had larger holes than de original sieves. The samples were shaken after instructions and then the material was weighted. We have also been taking out samples for microbiological analyses from the silos on 13 of the farms.

In this thesis a rural network in Norrbotten, Sweden, has been to designed and planned with the purpose of improving distribution reliability by exchanging existing overhead lines with underground cables. General network design considerations are discussed as well as the ones for the specific low voltage grid. During the design phase the maximum power of domestic consumers has been estimated using Velander?s method. Currents, voltage drop and impedance of the network have been calculated and fuse operation and selectivity has been considered.

The purpose of this Master?s thesis is to examine the function of public libraries on the social web, focusing on reading promotion and reading stimulation. For an understanding of the larger context regarding public libraries on the social web, we conducted online interviews via email with people in the Swedish library profession, together with a content analysis of various texts on the subject found in library journals and on the Internet. Furthermore to identify the public library's practice on reading promotion and reading stimulation on the social web, we did interviews with librarians at a public library on their use of a blog for this purpose, together with a questionnaire handed out to the library's users on their use and conceptions of the blog.The conceptual framework of this study consists of four key aspects in the theoretical and empirical definition of Library 2.0 presented by Holmberg, Huvila and Widén-Wulff. The results showed that the public library can create a substantial value through its use of the social web, but it?s necessary to have a clear vision of the desired outcome.

Social media has become an important marketing and communication tool worldwide, mostly through the largest social platforms Facebook and Twitter. With two-way communication via Internet companies has gotten the opportunity to interact and communicate directly with their customers. Facebook has been the focus point through the study because it has shown to be the most efficient and frequently used platform for communication. Our study aimed to confirm how communication via social media actually looks like. To be able to reach the best results, we have conducted the study from a phenomenological approach, which means; usage of qualitative semi-structured interviews to reflect the respondents experience on the phenomenon social media as a communication tool. Social media has shown to be a great way of communicating externally for companies who are willing to spend time engaging in the platform.

Today most studies regarding marketing are made on traditional marketing channels, answering questions like which jingle is best or which TV-channel a company should focus their marketing budget on. There is also the science regarding the best way of marketing on Social Networking sites or how to get as many 'likes' as possible, and so forth. However research has also been made in the field of in-store marketing and how a retailers or brand owners can affect customers in "the moment of truth". Until now most of these studies discuss how to get the attention of the customer in the store since both time as well as level of commitment in general is scarce when a customer is in a grocery store doing the necessary weekly- or complementary-shopping. It seems like most of them make the very same conclusion; catching the attention of a customer is vital to sell them your product.

Utvecklingen av förbandsmetoder är viktigt för att utveckla konstruktionslösningar. Under det senaste decenniet har forskning på limmade förband utförts, främst på inlimning av stålstag och plattstål i limträ. Förhoppningen är att spänningen ska fördelas jämnare i förbandet och att brott ska kunna undvikas. Hypotetiskt sett skulle det kunna göra knutpunker utan synliga förband möjliga vilket även skulle gynna arkitekternas önskemål.Genom en sammanställning av tidigare forskning dras en jämförelse mellan testresultaten och en antagen knutpunkt som belastas av egentyngder och variabla laster. På så sätt kan limmets kapacitet konkretiseras.

This report has a dual focus. The first goal was to increase the knowledge of how the use of electricity in a residential building is distributed. Electricity in residential buildings is used for lighting in common areas, elevators, pumps and many other appliances. The electricity used for these different parts is to a great extent unknown. A few studies have been carried out and the result of these is referred to in this report.By means of measurements and approximations the use of electricity for various appliances became known.
