Modellering av manövercylindern för Nosstället på JAS39 Gripen
When models are used to describe physical phenomenon during development or modification of a technical system, it is often possible to reduce both the time needed and the overall development cost. With the use of models it is also possible to investigate the potential of the selected solution, without the need for any expensive details and testrigs. In many cases it is also not possible to test all the aspects regarding the functionality that are desired from the system, without using the complete and final product.In this case a model based approach has been used to optimize the different parameters in the new snubbing mechanism for the Nose Landing Gear Retract Actuator on the JAS39 Gripen.During the simulations, upper and lower boundaries were calculated for the length of the spring and the diameter for the restrictor. The governing constraints were given by the requirements for the retraction time during cold conditions and that the amplitude of the alternating loads in the uplock mechanism were brought to an acceptable level.The most promising results from the simulations were then used in a limited number of trials in the hydraulic rig to verify that the configurations comply with the requirements.The final parameters for the snubbing mechanism were chosen to 35±1mm for the spring and 0.4-0.5 mm diameter for the restrictor..
Agent Provokation - En studie kring avsändarens påverkan på provokativ reklam
Even though provocative marketing is a widely used tool among companies to distin-guish themselves from the crowd and catch the attention of consumers, there are several variables that remain relatively unexplored. This paper aims to investigate what impact the brand has on how provocative advertising is perceived and how it affects attitudes and behavior. An experiment was conducted where several well-established measures of ad effectiveness such as brand attitude, buying intentions and word-of-mouth intentions were used to analyze the effects of brand knowledge. The results show that a provocative advert lowers attitude and buying inten-tions for the established brand while it remains unchanged for the unestablished brand. This implicates bigger freedom for unestablished brands to elaborate with provocative elements in their marketing.
Modularitet och objektorientering : Byggandet av ett program som kan visa en molekyl
The development of IT systems is usually accomplished by some form of system development methodology. It can be performed as the waterfall method, where each phase is completed before the next begins. One of the reasons to follow a development methodology is that the process is more structured, faster and that the product will have higher quality. One risk of not using a system development approach is that the code can be unstructured and difficult to maintain.This paper describes an alternative method in which the development occurred without the use of any system development methodology. This has been possible because there was a clear goal of the program that should be developed.
Lathunden ? för dig som vill göra rätt från början : Ett arbete om att öka förståelsen för ett nytt CMS-system genom teknisk kommunikation.
Syftet med mitt examensarbete var att undersöka vilka faktorer som gör teknisk kommunikation tillgänglig och lättförståelig. Det skulle leda fram till en läsvärd lathund för användare av ett nytt CMS-system. Arbetet har genomförts i samarbete med Telia, som är inne i ett förändringsarbete gällande sina informationssystem. De ska införa ett nytt så kallat PIM-system (Product Information Management), som ska innefatta ovan nämnda CMS-system och kommer innebära ett förändrat arbetssätt och nya arbetsuppgifter för min berörda målgrupp. För att lösa problemet har jag tagit hjälp av en fokusgrupp och gjort en webbenkät. Jag har ställt mig frågor om vad teknisk kommunikation kan bidra med vid framtagning av ett instruerande material, samt i vilka syften användarna kan tänkas läsa den typen av material. Med hjälp av teorier och ovanstående metoder producerade jag ett förslag på hur lathunden kan se ut. Jag testade också förslaget på målgruppen för att få deras åsikter, i syfte att förbättra slutresultatet..
Effekter av PR kontra reklam - är beaktande av produkt en försummad aspekt En studie av PR och reklams relativa kommunikationseffekter vid olika grad av engagemang för köpet och produkten.
Using stimuli with identical information in both PR and advertising, this study seeks to explain how content class together with the level of involvement affects the communication effects of marketing messages. There is currently no established way of measuring the value of PR, and contemporary PR metrics do not take into account what effects PR actually generates. PR is often said to have an advantage over advertising due to the effects of third party endorsement, but previous empirical assessments show inconsistent results regarding what effects each content class generates. The result of this study is that PR is stronger at building recall, interest and credibility, and that it has less perceived selling intent than advertising. Results differ somewhat between different levels of involvement, but the conclusion is that this might not be attributable to the level of involvement per se but rather to the type of products being used in stimuli - a conclusion that seems valid for previous research as well.
PLM-SYSTEM FÖR TILLVERKANDE MINDRE FÖRETAG : EN STUDIE OM LÄMPLIGHETEN AV PLM-SYSTEM OCH FÖRANKRING GENOM CHANGE MANAGEMENT
This study aims to investigate how small scale manufacturing companies reason around an implementation of a PLM-system, as well as the suitability of these systems compared to larger companies. The study is built on a qualitative method. Initially, secondary data was gathered through books, articles and reports. Primary data was gathered through four interviews. Two interviews were performed with PLM resellers, one interview was performed with a PLM developer, and one interview was performed with a small scale manufacturing company that opted to not implement a PLM-system.The results imply that overall differences between larger and smaller companies exist in regard to the need of PLM systems.
Hisskärna av skalväggar i höga byggnader : Ett alternativ till den platsgjutna kärnan
A common way to stabilize high rise buildings is to use an elevator core built of concrete. Today, we use to build these elevator cores of in-situ concrete. Precast concrete twin wall (double wall) is a semi-finished product that has become more common in recent years. This diploma work studies how the twin wall works out as structural elements in an elevator core. The work also shows some possible ways of designing twin walls and highlights some important parts of the design that will be vital to the stability of the building. The result shows that it is important to think through where the element joints should be placed.
Miljöoptimera avfallsindustrin i Sverige : - återvinn restprodukten gips
One of the most common ways to produce heat and electricity in Europe today is by the incineration of waste or combustion of coal. These materials can be very sulfurous and during combustion sulfur dioxide is produced. This is an environmental and health related toxic substance which is why power plants have strict regulations on removing it from the flue gas. Sulfur dioxide is removed from the flue gas by adding a limestone reagent. The sulfur dioxide reacts with the limestone and the synthetic product obtained is ?Flue Gas Desulfurization gypsum?.

The focus lies on distributed directory services and models for secure and robust data propagation in TCP/IP networks.
Sit and Go : Ett hjälpmedel som underlättar för rullstolsanvändare vid matlagning
Antalet personer med rörelsehinder förväntas öka i takt med att allt fler människor lever längre med sin funktionsnedsättning. För att öka självständigheten hos de rörelsehindrade måste nya innovativa hjälpmedel tas fram och redan befintliga hjälpmedel vidareutvecklas.Idén till projektet uppkom då en av projektdeltagarna under en längre tid har sett sin rullstolsburna familjemedlem hitta på egna lösningar vid matlagning på spisen i ett ickehandikappanpassat kök. Huvudsyftet med projektet har därför varit att lösa de problem som rullstolsanvändare kan ha vid matlagning på spisen, till exempel att de inte når eller ser. Målet har varit att ta fram en fungerande prototyp för att kunna utföra användartester. Det här för att säkerställa förbättrad ergonomi och möjlighet till ökad självständighet hosrullstolsanvändaren.Projektet resulterade i en användarvänlig fungerande prototyp.
Sammanställning och produktion av ritningsunderlag till båt
Hanterbara båtar is a new company who builds alumina boats customized for people in wheelchairs. Due to the fact that the company only built two boats yet, the production documentation is not complete. The drawing that does exist is not in an exact standard which makes production planning harder.The purpose of this work has been to make the production of the boat easier and simplify further development and modification. Product development in the form of optimizing details is also one of the main purpose of this work.This is all done by making a 3D-assembly of all the existing drawings. After this is done new drawings will be made and added to the main assembly.
Strategisk marknadsföring av produkter av rapsolja :
The background to this study is to find alternative ways of size rationalization. My vision is to
take the basic conditions and make the best and most profitable of them. I have chosen press
of rape oil because it?s interesting and the investment to get started is relative small. The
opportunity to use outmoded and unrational buildings which often are found at many farms to
something that gives money instead of costs money is also an argument.
LOCAL ADAPTATION IN EMERGING MARKETS ? in theory and reality : Study of the Swedish subsidiaries in China
Some MNEs encounter frustration or failures when they enter a new market. The main reason is due to a lack of adaptation. There is a lack of theoretical study about the local adaptation phenomenon of Swedish MNEs in China. Most studies are at the level of experience. Therefore, the purpose of this study is to find out the dimensions subject to local adaptation and their degree for the Swedish MNEs in China.
Flödesekonomins dimensioner : supply chain management
It is of increasing importance to in the most effective possible way, manage and control all the transactions of raw materials, products and information that are exchanged between an organization and all its operators. These flows and the need for strategy and managing the processes of planning, implementing and control of the supply chain, has given name to the concept supply chain management. Supply chain management involves all movement and storage of raw material, and all the processes that is needed to manufacture a product from origin to consumption. Globalization, technology and increasing time and quality-based competition are all driving forces behind the concept and reasons for an increasing interest in supply chain management.The purpose of this essay is to by using a qualitative case study examine which decisive success factors that can be identified for effective supply chain management. We have compiled different theories on the subject to use for analyzing a case study Li & Fung, who is a successful supply chain management company.
Kloning av möjlig promotorsekvens uppströms kloritdismutas i Ideonella dechloratans.
Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.
