Kartläggning av informationsbehov
This report is the result of a thesis carried out during the spring of 2010 at Sandvik Coromant in Gimo. The purpose of this thesis has been to make an inventory and mapping of information used by flow groups that are most relevant for the day-to-day work. This mapping will then form the basis for information supplied by an automated system.The project consisted of:Identifying how the information is supplied today.Inquiring into the needs of an automated system.Which needs of information that will be provided by the system.Data collection occurred in two ways, both through observations and interviews. Observations of the participants were carried out early in the thesis, where the aim was to create a picture of the problem, and gradually develop a basis for the actual interview study. At each observation, an unstructured observation was used, which means that all activity was recorded.
Projektledning & Kreativitet
För att finansiell rapportering ska ge läsaren en så klar bild som möjligt krävs en viss grad av harmonisering och upprättande av redovisningsstandards. Risken blir annars att redovisningen inte blir jämförbar och transparent. I december 2001 kom Redovisningsrådets Akutgrupp med ett uttalande som sa att koncernbidraget ska redovisas efter ekonomisk innebörd istället för, som tidigare, en bokslutsdisposition i resultaträkningen. Det problem som då uppstod var hur de företag som följde, och följer, Bokföringsnämnden skulle göra. Därför har Bokföringsnämnden under 2006 och 2007 skickat ut remisser med förslag på hur koncernbidraget i framtiden ska redovisas.
Induktiv provning av ferritiskt rostfritt stå
The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.
Ett flervariabelt feldetekteringssystem för övervakning av bärlagertemperaturen i vattenkraftturbiner
The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.
EFFEKTIVISERING AV DELMOMENT I PROCESSKARTLÄGGNING
Den här C-uppsatsen har gått ut på att göra en processkartläggning på återuppbyggnaden av Vivallaskolans bollhall som har brunnit ner under slutet av oktober 2010. Utifrån processkartläggningen har det gjorts analyser och observationer på aktivitetsflödet. Där framgår det vad som har gått bra och mindre bra. Till det som har gått mindre bra har förslag till lösningar tagits fram. I dessa lösningar ingår metoderna: PDCA (s.21), BIM (s.21) och Ishikawadiagram (s.21), som tydligt visar förbättringsåtgärder.Processkartläggningen och lösningsförslagen har tagits fram utifrån observationer i form av besök på arbetsplatsen samt läsning av litteratur och elektroniska källor.
AP7 och fyra storbankers Sverige- och Östeuropafonder : En riskjusterad utvärdering 2003-2009
AbstractThe purpose with this essay has been to gain a greater understanding and clarify how an arena can create value within place marketing and development of a place brand. This will be achieved through a description of which values an arena causes in the surrounding areas and an understanding of how these values can be interpreted through the place brand. We decided to base our study according to the following two questions:1. What are the underlying reasons why there has been such a big trend with arena project?2.
Assuandammens påverkan på Nilen, Egypten
Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.
Kassaflödesanalys - Direkt/Indirekt metod : En studie om vad som styr de olika företagens val av metod vid upprättande av kassaflödesanalysen.
Det finns bestämmelser i ÅRL att börsnoterade företag skall bifoga en kassaflödesanalys i sin årsredovisning för att redovisa en likviditetsförändring under året. Kassaflödesanalysen upprättas antingen genom den direkta eller indirekta metoden. De företag som följer IAS 7 uppmuntras till att tillämpa den direkta metoden, före den indirekta. Trots detta fortsätter en stor del av de svenska företagen att tillämpa den sistnämnda. Syfte: Syftet med denna uppsats är att undersöka de bakomliggande faktorerna till varför svenska företag använder indirekt eller direkt metod vid redovisning av kassaflöden. Metod: Det är en deduktiv studie som testar teorin i praktiken, där fyra kategorier undersöks (Tradition; Go with the flow; Lämpligare info; Mindre kostsam).

It is based on interviews with people from several different technological companies, within different lines of business, all of which are customers to A?F?s department of product development.The results show that there are seven critical factors for project efficiency and effectiveness.
Det papperslösa frukostbordet - En undersökning om den tryckta dagstidningens framtid
As revenues from newspaper advertising plummet and their readers loyalty erode, the need to understand newspapers' changing environment and the actors involved in this change is growing in importance. Evidence is the entire industry is entering into a restructuring phase and that this restructuring is driven by the rapid consumer adaption of internet media.In this thesis I elaborate on "how the Internet is affecting the conditions for value creation in printed newspapers" and "how the Internet is affecting the conditions for other actors involved in the printed newspaper's value creation". These two questions land us in the bigger question of "Does the Internet act as a compliment or a substitute to the printed newspaper ".To answer these questions the printed newspaper is represented as the actor in the middle of content producers, advertisers and consumers. It is in its role as a means of distribution and as a co-ordinating force that we study the value creation of the printed newspaper. The empirical base of this thesis is a qualitative participant observation where the author during a period of time interacted and collected data from the open discussion in blogs by several of the industry's top influentials combined with material from seminars and reports on the current state of media.
Elevers meningsindelning : Användningen av interpunktion, konnektivbindning ochsatsradningar i elevtexter från årskurs 3 i svenska ochsvenska som andraspråk
The aim of this study is to analyse how pupils in grade three use punctuation and howthey divide texts into sentences. The material in the study consists of 41 texts by pupils,divided into two types: narrative text and analytical text, written both by pupils withSwedish as their first language and by pupils with Swedish as their second language. Inthe study the pupils? use of connectives and comma splices has been studied, and therelationship between graphical and syntactical sentences in the texts. The studycompares the results for narrative and analytical texts and the differences between L1and L2 pupils.
Skadedjursbegränsare i horisontella avloppsrör
The purpose with this project was to invent a product that secures buildings sewersystems against rats. The problem was presented to us by a local building maintainer inHalmstad, who had experienced big problems with rats in his real estate. The project hasbeen carried out by Per Johansson, Robert Lidén and Niclas Nilsson under our ownauspices. We are primarily sponsored by AMLI Business Partner but also byInnvationsgruppen, Halmstad Fastighets AB and Anticimex.To be able to secure a whole building with only one product we came to the conclusionthat the product must be placed in the horizontal sewer pipe that connects with themunicipal sewer system. Our goal was to invent a product that prevent rats from passingand at the same time not affect the water flow.
Volymmätare för tall- och grankott
This thesis describes the planning and development of a volume meter of pine and spruce cones. The product was designed and developed for Stigsjö Skog och Frö AB in Härnösand. It was developed taking into account a number of requirements set by the supervisor David Zetterlund. The main requirements were that the volume measurement would be fast and give accurate results. These are two requirements that are missing in today's volume measuring method which is very problematic for the company.The plant was visited several times in Härnösand, mainly to discuss the generated concepts with the supervisor and perform tests on the prototype.

Analys av QoS i mellanvaran Meteor
This thesis is closely related to the Dynamically Self-Configuring Automotive System(DySCAS) project. DySCAS is a middleware for electronics in an automotive system. Thethesis work has been performed in cooperation with ENEA. Parts of the demonstrationplatform Self configurable High Availability and Policy based platform for Embeddedsystem (SHAPE) developed for the DySCAS project by ENEA have been used in theimplementation phase of this master thesis.The goal of this thesis was to evaluate how the Meteor MW, an offspring of the DySCASmiddleware, should handle QoS and to design a Quality of Service Manager (QoSM) for theMeteor MW that fulfilled hard real-time requirements. The thesis also had the objectiveof analysing and identifying the requirements on such a QoSM from a QoS perspective.Specifically the requirements to guarantee real-time support for applications running onthe MW.
