En modern dieselmotor utnyttjar Common-Rail bränsleinsprutning med solenoid- eller piezoelektriskt aktuerade spridare och multipla insprutningar per förbränning för att erhålla ett önskat utseende på cylindertryckskurvan.Användandet av multipla insprutningar per förbränning medför flera möjligheter. En sådan möjlighet är begränsandet av bullernivån vilket erhålls genom tillsättandet av en liten mängd bränsle tidigt under cykeln vilket i sin tur minskar den förblandade delen av förbränningen som äger rum då huvuddelen av bränslet tillsätts. Denna teknik kallas för pilotinsprutning. En annan möjlighet är införandet av en insprutning sent under cykeln, vilket höjer avgastemperaturen och kan förbättra responsen under transienter, regenerera partikelfilter eller möjliggöra användning av SCR vid driftsfall med naturligt låga avgastemperaturer .De ytterligare frihetsgrader som tekniken medför gör att kalibrering av nya motorer blir en alltmer komplex och tidskrävande process. Ökad förståelse krävs kring hur olika insprutningsmängder och tidpunkter påverkar cylindertrycket och därigenom motorns verkningsgrad.

SAMMANFATTNING I detta examensarbete har vi genom kvalitativa intervjuer undersökt hur studie- och yrkesvägledare på kommunala och fristående gymnasieskolor i Skåne upplever den konkurrens som finns mellan skolor och hur den eventuellt påverkar deras arbete. För att få en förståelse för studie- och yrkesvägledares yrkesroll och arbetssituation har vi bl.a. gett en beskrivning av styrdokument, etiska regler och konkurrenssituationen mellan skolor. Vid vår tolkning har vi utgått från begreppen organisationskultur, skolkultur, syokultur och psykologiskt kontrakt. De slutsatser vi kan dra av vårt resultat är att samtliga vägledare menar att det finns en konkurrens mellan gymnasieskolor. Hur omfattande den är finns det inget entydigt svar på.

The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.

Abstract:The old established description gunboat diplomacy has in modern time changed to a broader and more nuanced definition called maritime diplomacy. But what is maritime diplomacy and how is it described? This essay analyses the theories from the Englishman James Cable and the American Edward Luttwak. Both Cable and Luttwak represent nations which have a global security interests and deploy their maritime forces worldwide. The foundation for their theories is power politics.

Title: When municipalities are keeping upAuthors: Hansson Käll, Ida; Jonasson, MikaelaTutor: Waks, CarolineCourse: Bachelor thesis, 15hp, Department of Business Studies, HT 2010Background: During the recent years social media has evolved into a powerful communicative medium. From an organizational standpoint social media has become a way for organizations to get closer to, and create a dialogue with, their environment. Swedish municipalities have began to use social media in their daily communication with the environment, but a problem has been raised about how public organizations should organize their social media when formal guidelines from the government are missing.Objective: The objective of this thesis is to examine how eight Swedish municipalities have organized their use of social media due to the lack of official guidance from the government, and also what difficulties that have occurred during this process.Method: The method used is qualitative with data collected through interviews with one respondent from each municipality.Results: The result show that the organizational solutions varies through each municipality but also the choice of social media. It has been important for municipalities to have someone in charge of the new communication tool since social media is a fast and communicative channel. Seven out of eight municipalities have already developed or are in process of developing their own formal guidelines on how to use social media.

Syftet med detta examensarbete har varit att utreda möjligheten att klassificera en vägbeläggningskvalitet genom att utnyttja signaler från en bils befintliga givare. Vidare är examensarbetet enförstudie till ett eventuellt större projekt, som skall leda till utvecklingen av ett komplettklassificeringssystem som underlättar för väghållaren (t.ex. Vägverket) att inventeravägbeläggningens kvalitet. Uppdragsgivare har varit Semcon AB i Göteborg.I arbetet ingick att sätta systemavgränsningar beträffande olika beläggningstyper som skall kunnadetekteras, vilka hastigheter som skall tillämpas vid mätningarna samt vilka signaler från bilensgivare som är relevanta att utnyttja.Arbetet bestod i huvudsak av insamling av mätdata samt analys av denna i MATLAB1. Utifrån deninformation som den insamlade mätdatan gav, kunde sedan ett robust klassificeringssystem skapas,vilket med god precision klarar av att klassificera fyra olika beläggningstyper.Examensarbetet visar att det finns goda möjligheter till ett fördjupat arbete som kan resultera i ettför väghållaren mycket effektivt klassificeringsverktyg som underlättar att upprätthållastatusinformationen beträffande vägbeläggningens kvalitet.

In relation to the development of IT-products it is very important that the software supplier is aware not only of the target group but also the field of application. Usability should characterize the whole IT-design process as, in relation to this context, design includes more than merely those aspects which are visible to and thus can be interpreted by the naked eye. The study examines the specific qualities and properties that substantiate the usability and the demands that a customer rightfully expects from an IT-product. The user and the customer are highlighted in the same context in order to demonstrate that it is through the customer that an IT-product is defined as being useful. Thus, from this perspective, the user and customer can be considered as being the same person.

Two of Swedens´s major banks, SEB and Handelsbanken, which appears in the same industry and have similar strategy. Both banks can achieve a similar result despite the fact that their reward system looks quite different. An issue that arises from this observation is the relative reward system to the rest of the economy control system.Our purpose of this paper is therefore to examine the reward system in the organization's financial management systems. We wonder if the reward system may be a function of economic control system, or part of the system, or perhaps made independent of the system and then gradually adapted?In our study, we choose to assume a reward system has three functions to manage, motivate and compose the employee group.

Rapporteringssystem på företag fungerar som underlag för budgetplanering, framtida investeringar och översikt över slutförd produktion. Det är även ett bra hjälpmedel för företag som har realiserat olika kvalitetssystem för att säkra och förbättra kvaliteten. Rutinerna för rapporteringen måste ske med hög precision för att undvika att felaktiga uppgifter läggs in. Sådana felaktiga uppgifter kan ge upphov till att underlaget i rapporteringssystemet blir missvisande för företagets framtida planering. Ifö Sanitär AB är företaget som har granskats i denna rapports undersökning för att identifiera vilka orsaker som ligger till grund för differenserna i rapporteringssystemet.

Sapa Heat Transfer AB (SHT AB) är en av tre delar inom koncernen Sapa Group, som ägs av det norska företaget Orkla ASA. SHT AB har produktion både i Sverige (Finspång) och i Kina (Shanghai). Företaget är en världsledande leverantör och utvecklare av aluminiumband som används i olika typer av värmeväxlare, främst inom bilindustrin.I flera steg av produktionen, som innefattar omsmältning, varm- och kallvalsning samt skärning, uppkommer ett skrotfall av aluminium. Detta skrot tas omhand och återanvänds som råvara i företagets omsmältverk. SHT AB har idag inget automatiserat IT-stöd för att prognostisera skrotavfallet, dessa beräkningar görs istället med hjälp av Excel.

According to The National Board of Health and Welfare, about 200 000 elderly persons get some help or support with eating or nutrition problems. This was approximately 2 percent of the population. Older people in sheltered accommodation in community care were not able to manage their own nutrition. The older people were dependent on the food that was offered to them, when and how the food was served. This was a specific responsibility for the nursing staff.

The aim of this project has been to raise the production efficiency of Daliff Precision Engineering through reduced transportation time and a more standardized manufacturing process. The problem has upraised because of a big and diversified product flora without any standard products and with just small batches ordered. The report also tries to show the work procedure with general analytical methods and be an example of how a similar problem can be resolved. The transportation time is being proposed to be reduced through a change in the layout of the factory. By moving a few manual machines, dispatch and burring to more efficient locations, the total transportation time will be reduced by 55 %.

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers. A big part of the project was also to find combinations of materials for all components in the gearbox, to reduce weight and maintain or improve the performance of the system. Belt drive was of interest to investigate as an alternative solution to the current design that can reduce wear on the system at a performance test performed in the company before the product is released to market.
