En jämförelse mellan traditionell och modern taktäckning av industribyggnader

Den här rapporten har som syfte att utreda vilket eldistributionssystem för offshoreenheter som sparar mest vikt och utrymme. De två elsystem som jämförs är GVAs standard system och Siemens Blue Drive System. Rapporten innehåller en teoretisk bakgrund för båda systemen och dimensionering av systemens kraftkablar samt beräkning av kabelvikter och komponentvikten för systemen. För att uppskatta kabel- rutter och längder kommer ritningsunderlag för GVAs offshoreenhet 7500 att användas.Resultatet visar att GVAs standard system är det eldistributionssystem som har den lägsta totalvikten med 168 ton, GVAs standard system har en vikt som är 101 ton lägre än Siemens Blue Drive System som har en vikt på är 269 ton. GVAs standard system har en lägre ström vilket gör att ledararean blir mindre och i med det blir kabelvikten mindre.

Naturhänsynen i FSC-standarden : vetenskap eller gissningar?

The Swedish FSC standard (Forest Stewardship Council) is a level standard used to certify forestry. All the major Swedish forest companies are using the FSC standard, and approximately 50% of the Swedish forests are FSC certified today. In the essay six items within the chapter on environmental issues and biodiversity are examined: the proportion of protected forest, the proportion of annually burnt clear-cut stands, the number of trees with large diameter, the amount of dead wood, the proportion of deciduous trees within a stand and the proportion of deciduous-dominated stands. The FSC standard states a level for all items, and the purpose of the essay is to analyse whether these levels are supported by research within the field of conservation biology. The validity of the levels of the six items is them discussed to evaluate whether changes are required to the next revision of the FSC standard.

Value stream mapping i praktiken : En fallstudie på Light My Fire

Titel: Value stream mapping in practice ? A case study at Light MyFireAuthors: David Rydman and Tomas ÖnnemarMentor: Veronica Ülgen SvenssonExaminer: Åsa GustafssonBackground: Companies push their prices in today's markets to be competitive, which means that companies need to find ways to reduce costs while maintaining profits. (Cudney, 2009) According to Bergman and Klefsjö 2007, the basic rule of quality improvement says "there is always a way to achieve higher quality at a lower cost". One way is to improve a company's processes to get a more efficient flow and improvements that may cut costs. (Bergman & Klefsjö, 2007) Why it's important to look at the processes are that they often contain waste that can be eliminated.

Alternativ till fortsatt elektrisk generering i Olidan

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

Biståndshandläggares uppfattning av begreppet skälig levnadsnivå och handlingsutrymme. : En kvalitativ studie.

Our aim of this study is to analyze how the concept of reasonable standard of living is by assistance officers in geriatric care, as well as the impact of their discretion on the assessment. We conducted a qualitative study with the help of interviews. During the collection of the empirical material, we have experienced greater confusion among assistance officers opinion about the concept of reasonable standard of living. We lacked a clear answer to the concept content. The interview subjects' responses did not differ so much, they said, among other things, that the concept is difficult to interpret, fuzzy, or that they do not have a good understanding of it.

Trådlös kommunikation för Anybus

The industry struggles with problems concerning physical damage to wiresand communication in remote areas. Introducing a wireless network canprovide a solution to these issues. However, introducing wirelesscommunication comes with a whole new line of problems that will becovered in this report. By utilizing the wireless communication standardIEEE 802.11 a product can easily be integrated into an existing wiredEthernet network (IEEE 802.3).An introduction to the standard IEEE 802.11 and a summary of existingproducts utilizing the standard for embedded systems will be giventhroughout the report. This report also tries to explain key parameters forwireless communication in an industrial environment.This project also consists of a design and an implementation part, where thechosen IEEE 802.11 standard will be integrated into the existing wiredAnybus-S Ethernet module from the company HMS Industrial Networks.The integration part of the project has resulted in a working prototype calledAnybus-S Ethernet Wireless that utilizes the IEEE 802.11b/g standard fortransferring data.The project has been really fun to participate in and it has been successful inthe terms that a working prototype exists, and the authors have gained theknowledge in the subject as intended..

It will also hold a central area which contains spaces necessary for the operation and construction of the facility, such as elevator hall, storage hall etc. The facility will have two ways of access: a vehicle ramp and an elevator shaft.

Effekter av olika skiftformer : En studie om effekter av olika skiftformer inom räddningstjänsten

Bakgrund: Uppsatsen tar upp problematiken kring att organisera arbetstid inom räddningstjänst. Grundförutsättningarna är att räddningstjänst är en High Reliability Organisation (HRO) och att det påverkar organisationen. I och med New Public Management (NPM) framfart och den ekonomiska situationen i världen har räddningstjänsten fått ett ökat krav på kostnadsbesparingar och resursutnyttjande. Då personalkostnader står för en stor del av räddningstjänstens kostnader kan förändringar av brandmännens arbetstid och skiftgång vara ett logiskt steg, något som skett i Greater Manchester Fire and Rescue Service (GMFRS).Syfte: Syftet med uppsatsen är ett ge ett teoretiskt bidrag till hur NPM influerade reformer påverkar en HRO. För att göra detta frågar vi oss vad de olika skiftformerna får för konsekvenser för de anställda och organisationen.Metod: Uppsatsen har en kvalitativ forskningsansats vid studerandet av fallorganisationen Greater Manchester Fire and Rescue Service och Storstockholms Brandförsvar.

Aktivering av en dissolvingmassa med enzymer före en konventionell viskosprocess

In conventional viscose manufacturing, a large amount of carbondisulfide is consumed. This amount has to be decreased to keep the production cost down and to reduce the environmental impact. The purpose with this work was to show if an enzyme treatment of a dissolving pulp could increase the degree of substitution in the viscose so that the amount of carbon disulfide consumed in the process could be decreased. Previous investigations by Kvarnlöf (2007), Engström et.al. (2006) and Henriksson et.al.

XML som informationsbärare för EDI

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used. The most common standard in Europe is EDIFACT, but with increased interest of using the Internet for business communication there is a need for a standard that is adjusted for use over the Internet.

Regional frihandel med miljöhänsyn? En studie av regionala frihandelsavtals förhållningssätt till konflikten med miljön

The relationship between free trade and the environment is often considered conflicting and the debates surrounding it are infected. My thesis deal with this conflict and how environmental concerns are integrated in three regional free trade agreements, North American Free Trade Agreement, The common market of the southern cone (MERCOSUR) and Southern African Development Community (SADC). I point out how the organizations differ from each other in this respect and I present a possible explanation to why they differ. The explanation is founded on the theory of the environmental Kuznets curve and that environmental concerns will depend on which level of development the member states in the organizations have. To judge and rank the organizations I have composed a model based on a pre-existing description of the trade and environment conflict.

SmartMedia-controller på chip

This report deals with the design of a controller for SmartMedia? flash memory cards, based on a hardware description found in the SmartMedia? Interface Library - SMIL. The design was made on logic gate level, using standard cells in OrCAD Capture. After simulation of the design in PSpice A/D, it was exported as an EDIF netlist, which was used to make a chip layout in L-Edit, a layout tool for making integrated circuits. The layout was made using a method called Standard Place and Route - SPR, where the layout tool places standard cells from a library and connects them according to the EDIF netlist.
