Konstruktion av ränndalskap CPD08
Our Bachelor?s Thesies has been performed in co-operation with Cellplast Direkt AB inLaholm. Our task was to develop a construction that cuts gussets to ceiling disposition as isused to isolation.Our goal with our construction was to increase the degree of automation so that theproductivity increased and also meet the market which is getting tougher and tougher due tothe future business cycle.Cellplast Direkt gave us free hands in order to enable new ideas. A pair different principleproposal was developed and prepared to a final structure.The Bachelor?s Thesies resulted in one PLC - governed machine with three engines that runthree different moves, wich does that the degree of automation increases and the risk forerrors decreases.We have developed a complete production bases to Cellplast Direkt and our hope is that thecompany comes to produce the machine in the future..
Interaktiva applikationers potential på internet - en kvalitativ studie av Saab Automobile AB
Saabs vision med de interaktiva applikationerna är att de ska tilltala både den nya besökaren och den lojale Saabkunden. Vi observerade tydliga attitydförändringar när applikationerna inte fungerade. Få kunde tänka sig att köpa en bil efter att enbart ha besökt Saabs hemsida då applikationerna i dagsläget inte kan ersätta känslan av att manövrera bilen själv. För att öka graden av ?stickiness? och ?flow? kan Saab integrera applikationerna i en värdekedja.
Farmers´ decisions factors : a case study
This study examined the factors influencing dairy farmers´ decisions to invest in automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.
Utvärdering av digitala provtryckssystem
Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult.
Robotstyrning med metoden Sliding Mode Control
The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.
Fuktproblem i chilenska småhus
Humidity problems and poor ventilation are factors that we associate with poor indoor airquality which are known to negatively affect health. Such problems have decreased with timein Sweden but, in other countries this is still a major problem especially during winter. InChile, this is most common in the central regions of the country, especially the Strait ofMagellan. This issue is primarily due to surface condensation happening indoors which bringsabout dampness which facilitates the growth of fungus and stains, foul odors, metal corrosionand more. This is due to a combination of poor ventilation and insufficient forms of heatingalong with buildings which have no insulation.
Försvarets roll i brottmålsprocessen ? En rättssäkerhetsfråga?
Titel: Vi sitter alla i samma vagn ? en observation av interaktionFörfattare: Malin JätmarkHandledare: Abby PetersenInstitution: Sociologiska institutionen vid Göteborgs UniversitetTyp av arbete: Examensarbete i sociologiTidpunkt: november 2007 ? januari 2008Syfte och frågeställningar: Syftet med undersökningen är att få en ökad förståelse av interaktionen ombord på en spårvagn. Frågeställningar:Hur interagerar människor ombord på en spårvagn?Hur kan mina observerade data sättas i samband med den inlästa teorin?Material och metod: Som teoretisk bakgrund använde jag mig huvudsakligen av Erving Goffmans begrepp och teorier angående interaktion, kommunikation och agerande samt Eviatar Zerubavel olika teorier om ?flow?, ramar, ritualer, kultur och uppdelning. Tidigare forskning belystes av två undersökningar som behandlade resande över lag men där vissa specifika delar behandlade interaktion och kommunikation.
Att handla till underpris genererar vinst, men fo?r vem? : En studie av underprissatta bo?rsintroduktioner och a?garstruktur pa? Aktietorget
Risk-free profit sounds appealing. The opportunity to arbitrage exists. Investments in underpriced IPO:s can generate profit, but for whom?Previous studies have shown that underpricing is a common phenomenon. This study intends to investigate whether underpricing and the arbitrage opportunity exists on Aktietorget which is a smaller venue.
Equity Premium Puzzle : teori och empiri
Syftet med uppsatsen är att diskutera det så kallade equity premium puzzle. Jaganalyserar teoretiskt den intertemporala konsumtionsbaserade CAPM (C-CAPM),sammanställer en del av litteraturdiskussionen som finns på området samt empiriskttestar C-CAPM på svensk data. Fenomenet equity premium puzzle innebär attöveravkastningen på aktier är så stor att det inte stämmer med den ekonomiska teorin.Enligt teorin beror C-CAPMs riskpremie på kovariansen mellan konsumtionen ochaktieavkastningen. Litteraturen visar att forskare inte har lyckats förklara equitypremium puzzle genom att ändra antagandena i grundmodellen. Den empiriskaundersökningen visar att equity premium puzzle även uppkommer på svensk data..

Tillförlitlighet hos trafikolycksklassificering
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Operativsystemsreplikering : Jämförelse mellan FOG och Symantec Ghost Suite
För att installera flera operativsystem samtidigt finns det olika verktyg avsedda för att underlätta denna process. Det finns både kommersiella- och gratisalternativ ute på marknaden. En av de ledande kommersiella replikeringsmjukvarorna är Symantec Ghost. I detta arbete jämförs Symantec Ghosts mot Free open-source ghost (FOG) för att mäta användbarheten med avseende på kritiska attribut. Kritiska attribut är baserade på utförandet av en fullständig replikeringsprocess samt hur en användare upplever hanteringen av mjukvaran.
Nätverk och makt - En fråga om makt och relation mellan politiker och tjänstemän
I have studied how network in a broad sense can affect decision-making. The primary purpose is to see if the political initiative somewhere disappears when it comes to understand the relations between power, actors and politics. The study discuss in a theoretical area that concerns the reliability in neoinstitutionalism to use as an analytical instrument. Some criticism is given to the theoretical standpoint in the sense that there is no power perspective included in the theory. I include a discussion about a concept of power, which I include to the theory.
