Kvalitetssäkring för Scaniasmotorkomponenter : Jämförelse med andra företag

Quality assurance for Scania engine componentsScania engines have become one of the world?s most renowned corporations in themanufacturing of engines. This is mostly due to the quality and performance thatScania have shown. However, this does not stop Scania from trying to achieve moresuccess in the fields of development and research to assure the quality of theirengines.The purpose of this thesis is to show how Scania ensures the quality of the enginecomponents, both those who made externally and internally at Scania, also inclusivethe manufacturing and assembly process.Three engine components were examined: D16 block engines, water pump andXP-Iinjectors. The study included the whole process from the step of supplying therow materials to the last step in production functional test.In this thesis an investigation of how other companies are working with qualityassurance was conducted.

Image follows structure

Background: The business market today is characterized by tough competition amongst the competitors to capture consumers? interest and money. One marketing tool companies can use to achieve this is the company?s image. The customer buys not only a product, but also the image that the company or the product is associated with.

Optisk undersökning av dieselsprayer från en höghastighetsroterande insprutare

There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.

This report is written for a consultant networking company with the purpose to review the development ofthe company's remote connections from a user friendly and security perspective.This includes an investigation of the possibilities to consolidate existing authentication methods foraccessing customers. The problem lies in the amount of methods being used. Through case study wefound that smart cards, SMS-service, software and hardware tokens exist.The only method feasible from a security perspective is smart cards. Since the method is not commonlyused by the company's customers a standardization of it would be counterproductive.Also, the purpose of this report is to investigate how the ongoing internal development of the remoteconnection will affect the company's clients. Within this framework we have also verified a designsuggestion.We interpret, after the completion of the case study, that the internal development of the remoteconnection is marginally affected by legal perspectives.

Analys och förbättring av en mätenhet för laddning av elfordon

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Kommunikation och samordning : En studie av internkommunikationen inom Region Värmland

This paper deals with the subject internal communication. We received this assignment from Region Värmland, an organization formed jointly by the 16 municipalities in the county of Värmland, to take responsibility for regional development, growth issues, culture and adult education in Värmland. The organization consists of a number of geographically dispersed units with specialized working areas. In this type of organization, there are high demands on internal communication as a tool to coordinate the organization?s different units and integrate their work, in order to reach the common goals.

Furthermore, the result shows that it can improve the communication, increase organizational learning and unity among coworkers. Finally social media can make organizations more effective..

Arbetsskador som drabbar marin maskinpersonal : En kartläggning av skaderiskerna för marin maskinpersonal ombord på svenska fartyg, samt en jämförelse av skaderisken med liknande arbeten iland

Syftet med undersökningen är att kartlägga skaderiskerna med att arbeta som marin maskinpersonal och jämföra skaderisken med anställda som har liknande arbeten iland. Undersökningen inbegriper även att kartlägga vilka typer av arbetsskador, som ger de mest allvarliga konsekvenserna för den anställde i förhållande till hur vanlig olyckan är.Undersökningen är en litteraturstudie där Arbetsmiljöverkets arbetsskadeanmälningar utgör grundmaterialet, där totalt 198 arbetsskador behandlades och kategoriserades. Transportstyrelsens statistik för ombordanställda jämfördes med Arbetsmiljöverket och Statistiska centralbyrån statistik över anställda iland. Detta för att se vilken yrkeskategori som hade högst skaderisk.Resultatet av undersökningen visar att arbetsolyckor under kategorierna ?Bära? och ?Halka/Snubbla/Trilla? och arbetssjukdomar under kategorin ?Tunga lyft/Arbetsställningar? är de arbetsskador, som ger de mest allvarliga konsekvenserna i förhållande till hur vanlig arbetsskadan är.

Modellbaserad drivlinereglering

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

Internal Market Harmonisation and Trade Implications for Non-EU Companies

After the formation of the European Union internal market in 1992, member state specific obstacles and barriers were largely removed. This was especially the case in harmonised industries where standardisation and technical regulation have led to legal certainty. Despite this, a large range of trade regulation continues to remain distortional to trade, in addition to the ongoing tariffs and subsidies. The key trade regulations relate to a number of areas involving technical regulations such as production labelling and the protection of intellectual property rights. Whilst policy makers claim justification based around the need to correct market failure in delivering desired outcomes, the question is whether these regulations are appropriate responses to market failures or if they have simply been imposed in an attempt to protect domestic markets.

Effektiv intern kommunikation : En studie av kommunikation mellan värdar och värdledare i en idrottsförening

AbstractTitle: Effective internal communication ?A case study on communication between a manager and the employees in a sportsclub.Number of pages: 40, without enclosuresAuthor: Susan AnderssonTutor: Peder Hård af SegerstadCourse: Media and Communication Studies CPeriod: Second term 2005University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: I aim to do a case study of a work situation, where there is no natural or direct form of feedback between the manager and the employees, and compare the purpose of the information efforts with how it is perceived by the employees.Material/Method: Qualitative research method, including an assembling method in the form of interviews, and a processing method of those interviews.Main results: All the used channels combined together (except one channel) seem to have created the right condition so that the content of the information can be perceived and used as the way it was supposed to, even though there?s no direct feedback of the information. The manager gets feedback indirectly and can therefore adapt the messages, or the information efforts, to the receivers.Keywords: Organizational communication, Internal communication, Information, Feedback..

Söktjänster för akademiskt bruk: En utvärdering av Google och Argos med frågor från en akademisk ämnesdisciplin

The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.
