Efter ett förslag om förändring och modernisering av lotsverksamheten lades fram, där det föreslogs att landbaserad lotsning eventuellt införs i framtiden, beslutade vi att undersöka och jämföra åsikter från verksamma inom lotsväsendet.Det finns risk att man förlorar viktiga delar av en väldigt stor kunskapsbank, om man inte tar tillvara på denna genom att beakta lotsarnas synvinklar, vid ett utvecklande och moderniserande av lotssystemet.Syftet var att kartlägga och kategorisera vad det finns för möjligheter och begränsningar med dagens lotssystem i förhållande till landbaserad lotsning. Vi har gjort en kvalitativ, fenomenografisk undersökning, där vi använt oss av intervjuer med öppna frågeställningar.Det visade sig att det var lätt att se begränsningar med ett införande av landbaserad lotsning, främst på grund av att lotsarna inte anser sig kunna utföra sitt arbete på ett tillfredställande sätt. Den ekonomiska vinsten rådde det delade meningar om, men majoriteten ansåg att besparingen skulle bli obefintlig..

During an excavation at Old Uppsala 571 raw garnets was found. In comparison with similar fragments from other sites in Sweden my aim was to prove a completely domestic production of garnets for cloisonné work. I have chosen to look at the archaeological sites of Old Uppsala, Valsta, Slöinge and Paviken and more closely at the material from Old Uppsala and Valsta. My theoretical framework has been to look at the garnets own agency in the contemporary society.Garnet cloisonné was a popular jewellery form during the Merovingian period on the continent although it came to an end in the early 7th century. It was during this time in Scandinavia a new sort of garnet, technique and paste was introduced and the garnet cloisonné was profoundly used for the gear of the elite and ritual objects.

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.

Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.

Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.

AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.

Bakgrunden till studien utgörs av ett interventionsprojekt vars syfte var att låta pojken öva på användandet av sitt hjälpmedel samt använda det i olika servicesituationer, dvs. att handla, gå på café eller motsvarande. Pojkens kommunikationshjälpmedel är en pratapparat i form av en bärbar dator med mjukvaran The Grid installerad vilken bland annat innehåller en ordprediktionsfunktion, en funktion att formulera fraser i förväg, samt en talsyntes. Uppsatsens material består av interventionsprojektets inledande och avslutande inspelningar i butik.

This master thesis deals with questions concerning facts and fiction in the world of Beatrix Potter's rabbits. The purpose is first and foremost to find the connections between the pet rabbits, that she used as art models, and the rabbits that came to life through her "tales".The method has been to gather facts through biographic reading, and to analyse Beatrix Potter's rabbit tales, using tools developed by Swedish picture book experts. The rabbit characters are thoroughly examined and so are the settings where the tales take place. Matters concerning Beatrix Potter's painting technique and illustration style as well as her literary and pictorial inspirations are dealt with.Conclusions are, that the fictive rabbit characters have indeed a lot to do with the fact that Beatrix Potter was interested in natural history and studied animal behaviour and anatomy in detail. For a long time rabbits, both wild and domesticated, were her favourite study objects which provided conditions for her rabbit fantasies.

Lameness from the carpus is not unusual in the horse. Multiple soft tissue structures such as tendons, ligaments, the joint capsule and synovial structures can be the originating source. All these structures can be examined with ultrasound, although a description of a systematic examination method is lacking. That is ? which structures, what they look like in an ultrasound examination, how to look at them in the best way, and in what order.

Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One technique to utilize and convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process), the difference from the traditional Rankine process is that instead of water as a working medium, an organic substance is used. The main component used in the process is a evaporator, a turbine, a condenser and a pump.

In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

Location-based services (LBS) contains of services helping users of finding positions of themselves or other objects. LBS applications can present information in varies types of ways, these could be threw speech, text, geographic symbols, photos etc. Not many studies have been done to examine the aspects of LBS communication and there is a demand for user and context centered mapping.The purpose of this report is to present a model for the development of user and context based services. The model will give guide lines of recommendations when implementing LBS. The different technologies that support LBS will also be noticed.

In today?s industry it is starting to get more and more interesting with wireless systems and solutions for applications. To be able to reduce the amount of cables drawn to various machines which takes both space and an extra fee for every cable drawn. Some systems might require the user to use a handheld device that is directly connected by a cable which in some machines might be inelegant for the user.The goal with this bachelor thesis is to develop wireless monitoring of the machine operators position that is working with heavy industrial machinery. The thesis started out with researching different techniques for positioning a transmitter indoors, this was done in order to get a better understanding on how to go about.

Örebro svets & hydraulik AB tillverkar lastknektar till Suzuki Garphyttan. På lastknektarna transporteras sedan stora rullar av tråd i stål. Knektarna har visat sig kollapsa efter viss tids användning och behöver därför en förbättrad konstruktion. Höga laster, tuff hantering samt ovarsamma lyft kan vara orsaker till att knektarna kollapsar. Örebro svets är väl införstådda var skadorna uppstår i nuvarande konstruktion och vill därför förstärka denna del och konstruktionen i sin helhet.Kraven på den nya konstruktionen, förutom att vara mer hållbar, är att befintligt mått mellan benen ska följas och att knekten ska vara staplingsbar vid transport till galvanisering.Nuvarande knektar har modellerats i CAD-programmet Pro/ENGINEER för att sedan analyseras med Finita Elementmetoden i beräkningsprogrammet ANSYS för att visa var deformation och spänningar uppstår.
