Hur enkel- & dubbelportsturbin i kombination med två olika avgassamlare påverkar gasväxlingsprestanda på en Scania V8

The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

Utveckling av ny musiktjänst på Google App Engine

Idag använder många band och artister utan skivkontrakt olika tjänster på Internet för för att publicera sitt material. Dagens populära tjänster saknar antingen en välutvecklad musikspelare eller en webbplats med community.Syftet med det här arbetet är att med hjälp av molntjänsten Google App Engine, programspråket Python och ramverket Django utveckla en mer komplett tjänst.Arbetet resulterade i grunden till en tjänst samt en rad positiva och negativa slutsatser gällande valet av teknik..

Internal Control - Efficiency in the Audit Process

The purpose of this research is to examine the implications of the provisions in the Swedish Code of Corporate Governance (the Code) concerning auditor attestation of the internal control report. We will focus on how the auditors? augmented responsibilities will affect the efficiency in the audit process.Our research indicates that the main benefit from reviewing the internal control report is achieving more reliable internal controls, which results in greater prevention of misstatements in the financial statements. This will affect the efficiency in the audit process since the auditor can place more reliance on internal controls when performing audit procedures. This implies that the benefits of preventing misstatements could outweigh the efforts and resources spent on reviewing the internal control report..

Sökmotoroptimering : Metoder för att förbättra sin placering i Googles sökresultat

This paper is a literature study on search engine optimization (SEO) considering the leader of the search engine market: Google. There´s an introductory background description of Google and its methods of  crawling the Internet and indexing the web pages, along with a brief review of the famous PageRank algorithm. The purpose of this paper is to describe the major important methods for improved rankings on Google´s result lists. These methods could be categorized as on-page methods tied to the website to be optimized or off-page methods that are external to the website such as link development. Furthermore the most common unethical methods are described, known as ?black hat?, which is the secondary purpose of the text.

Regressionsmodellering av dynamiska råemissioner från statiska mätningar

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

Kommunikationsstyrning vid reklamation : En studie av stormarknader

This study focuses on the internal marketing and how it affects the complaints by companies? communication control. Our purpose with this subject is to increase the understanding of which components affects the relation between internal marketing, communication control and complaints. We have chosen the subject, internal marketing because it caught our interest in an earlier course. On the basis of the literature of costumer complaint there have not been so much research about it and that is why we have chosen this perspective on internal marketing.This study is based on a qualitative approach.

Karaktärisering av avfallsbränslen

All products will eventually end up as waste, which in a sustainable society has to be handled in an efficient and environment friendly way. This report focuses on waste fractions meant for combustion, often difficult to characterize. However, more homogeneous fractions that are treated biologically are also discussed.The study concerns the region of Borås, Sweden, where the waste plant Sobacken has provided a good starting point. On this site, fuel to the Energy-from-Waste plant of Borås Energi is prepared and the biological waste is treated through anaerobic digestion.One important part of the study has been to collect experience-based knowledge from the technical staff at Sobacken and Borås Energi. This information was compiled into an overview of wanted and unwanted fractions to the preparation plant and the boilers respectively.

Alternativ motorinkapsling

The problems caused by the current engine casing in aluminum for Volvo Buses Corp. are the mainfoundation for this degree project. Lack of maintenance combined with a construction poorlyadjusted for assembly has resulted in the fact that the engine casings rarely get reassembled whenthe service is completed.The degree project has mainly been following ?Olssons.

Märkta medarbetare - En studie om internt varumärke

Through this study we want to enlighten how different companies work with their internal branding and how well they succeed in this process. We also want to examine if there are any differences in this work depending on the companies market position. Following question is used to investigate this process;- In what way and how well are companies working, depending on market position to implement and maintain their work with the internal brand?For the study a theoretical model was created based on our existing theory. The model contains three main variables; create, communicate and uphold; i.e.

Feldiagnos för RM12 baserad på identifierade modeller

The jetengines of today are growing in complexity. Reliability for aircraft engines are of extreme importance, mainly due to safety reasons but also economical ones. This master thesis deals with faultdiagnosis in the turbine section of RM12, the engine used in Saab/BAe's Gripen. Three different faults which can occur in the turbine section was studied. These faults are: clogged fuel nozzle, hole in outlet guide vane and sensor fault.

Utveckling av arbetsmetod för DFA

Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.

Programvaruapplikation som stöd vid granskning i Dimensions

AbstractThe control of quality standard ISO 9001 has made the internal audit to be experienced as police authority and paragraph control. Because of that, motivation for internal auditors is low. To counteract the experience, there is a possibility to integrate internal audit with improvements in company?s processes. Theory has shown that a qualified and competent auditor can provide information that can help the organization's managements to make the right decisions that will improve product quality and result in new customer contracts.An opportunity to observe an internal and external audit at one of the case companies gave rise to this study.
