Gradningsutrustning: förbättringsförslag för utrustning till gradningsrobot FANUC vid Ferruform AB, Luleå

Vid skärande bearbetning uppstår vassa grader och skarpa kanter. Det måste finnas en operation i tillverkningsprocessen som tar bort dessa. Syftet med projektet har varit att ta fram en säker och stabil gradningsutrustning till en industrirobot, då den utrustning som används idag har brister i både stabilitet och effektivitet. När den automatiska gradningen fungerar tillfredsställande kan ett stort antal mantimmar sparas, eftersom personal inte behöver korrigera och grada detaljerna manuellt. Undersökningar av miljön kring den befintliga gradningsutrustningen samt en djupgående analys av konstruktionen visar på svagheter i både konstruktion och luftförsörjning.

Betydelsen av ett moderbolags insyn och kontroll över sitt dotterbolag vid prissättning av koncerninterna lån

Transfer pricing including internal loans have increased in recent years, making it easier for companies to minimize their taxable income. After the Swedish court case Diligentia, there have been discussions regarding the influence of a parent company's transparency and control of the subsidiary with regards to the interest rates on internal loans. In court cases that followed Diligentia, the Swedish Tax Agency argued that a parent company always could be assumed to have sufficient transparency and control of the operations in the subsidiary, and therefore reduce the risk on their debt obligations. This thesis seeks to analyze the effects of the transparency and control a parent company has with regards to interest rates on internal loans. The analysis is conducted by analyzing court cases similar to Diligentia.

Arbetsprocess för verktygsoptimering

Syftet med detta arbete var att ta fram en arbetsmetod som underlättar arbetsgången med verktygsoptimering på Scanias produktionsenhet för motorkomponenter. Metoden ska beskriva hur arbetet ska ske internt såväl som hur arbetet ska ske med verktygsleverantörer. Arbetsmetoden ska både behandla hur optimering av befintliga bearbetningsprocesser ska gå till samt hur tillvägagångssättet för verktygsoptimering vid anskaffning av nya verkstadsmaskiner.Som metod valdes att studera befintliga arbetsprocesser på Scania samt att utföra semistrukturerade intervjuer med personer i funktioner inom motor som idag arbetar med dessa frågor. Dessa funktioner har främst varit bearbetningstekniker, beredare, metodlabb, inköp, produktionstekniker, produktionsledare och operatörer.Intervjuer genomfördes också med representanter för de tre mest anlitade verktygsleverantörerna.Resultatet blev att en befintlig tidigare okänd väl fungerande arbetsprocess har identifierats. Processen lider idag av vissa svårigheter vid dels initieringen av nya uppdrag samt vid införandet av framtagna lösningar.

Background: In a world that are becoming more and more aware of the climate changes that occur as a consequence of the increasing emissions around the world companies? experience that the opinion blame the internal processors for this. Many companies feel forced to align their strategies to the environmental goals set by the community. Some of the emissions the companies? operations can be linked to business trips and it is therefore interesting to see how these can be reduced by using different performance measures.

Modellen och materialet

Tycho Hedéns Väg in Uppsala has evolved from being a through fare passage and highwayto the oversized road frame running through the city it is today. At the present time, dueto the relocation of the E4 highway east of Uppsala, Tycho Hedéns road creates a barrierbetween the north eastern area of Uppsala and the remaining parts of the city centre. Theroad is designed to endure heavy traffic and high speed limits, generating a surrounding urbanarea were inhabitants are complied to follow the standards set for a high traffic-accessibleenvironment. Furthermore, the heavy traffic has led to the turning of both urban roadsidesaway from the actual road. The aim of this project and proposal is to show the possibilities ofhow the innate features of Tycho Hedéns road can be used more advantageously to mend thecity area of Uppsala.

VTEC O157 hos får : en jämförelse av stammar isolerade från får, nötkreatur och människa

Verotoxinproducerande E. coli, VTEC är en zoonotisk bakterie som kan orsaka allvarlig sjukdom hos människa. Forskning kring VTEC har framför allt varit inriktad på nötkreatur vilka tidigt utpekades som en viktig smittkälla för människa. Förhållandevis få studier har gjorts på får och fårprodukter och kunskapsluckorna är stora både vad gäller förekomst och utbredning av VTEC hos detta djurslag. Syftet med denna studie var att utreda om får kan utgöra en smittkälla för människa vad gäller verotoxinbildande E.

iPad som pedagogiskt verktyg i grundsärskolan : Några lärares beskrivningar av hur de arbetar med iPad i ämnet svenska

The aim of this study is investigating how some Elementary School teachers of special classes describe how they use iPad as an educational tool when teaching Swedish. To find out I have carried out an interview investigation. I have analyzed results using theoretical concepts from the sociocultural perspective, scaffolding and artefacts.The cummulative result shows that teachers describe that they practice linguistic consciousness and that pupils are trained in writing Swedish in this subject. Another result shows how all teachers describe that they work face-to-face with pupils using iPads in Swedish lessons. Further results show how teachers present possibilities of using iPad as an educational tool when teaching Swedish.

Nekande tvångsmakt i Operation Unified Protector

There are several competing views on how to best utilize air power. Following his quantitative study of air power, Robert Pape developed a theory which focuses on undermining the target state's military strategy. According to Pape it is possible to explain the outcome as a result of military vulnerability. This essay seeks to determine if Pape's theory can predict the outcome of Operation Unified Protector. By using a mixed methods approach on four hypotheses, it will be determined if the operation was a successful case of coercion, if NATO acted according to Pape's model and whether this achieved the desired effects or not. The results reveal that the theory could not successfully predict the outcome of the conflict.

Diskkrypteringsprestanda i GNU/Linux

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..
