Full textGrafisk presentation av data som lagras i databaser uppnås vanligen med programvara på en stationär dator som kräver att data överförs från databaser till den lokala datorn och sedan bearbetas med programvaran. Denna metod kräver kunskaper inom databasrelaterade språk och verktyg som SQL, och är därmed krävande eller otillgänglig för användare utan en viss nivå av utbildning eller erfarenhet inom dessa språk och verktyg. Målet med denna studie är att skapa ett program som eliminerar behovet av avancerad kompetens inom dessa språk och verktyg för att göra det möjligt för en större grupp av användare att grafiskt presentera data som lagras i databaser. För att uppnå detta mål har en webbapplikation utvecklats som har ett simpelt grafiskt gränssnitt för anslutning till en fjärrdatabas och för att skapa diagram från data som lagras där. Applikationen genererar förfrågningar till databasen enligt användarens inmatning i det grafiska gränssnittet. Av säkerhetsmässiga och praktiska skäl har applikationen utvecklats med ett system för rollbaserad kontohantering.

Full textDetta examensarbete har utförts åt Saab Avitronics, en affärsenhet inom Saab AB, verksamma inom elektroniksystem för militära flygplan. I denna miljö är tillförlitlighet och vikt av stor betydelse. Inom elektronikkylning skulle möjligen grafit kunna användas för att öka tillförlitligheten och minska vikten. Grafit är ett anisotropiskt material vilket medför hög värmeledningsförmåga i två riktningar (i planet) och en relativt låg värmeledningsförmåga i den tredje riktningen (genom tjockleken). Syftet med arbetet har varit att utreda om grafit är ett adekvat material att använda som värmeledare till bärare för kretskort. Bärare används för att ge mekaniskt stöd samt kyla komponenterna på kretskorten genom att leda bort värmen. Arbetet har fokuserats på att omkonstruera en bärare till ett högeffektkort där kapaciteten för värmetransporten är nära sin maxgräns för konstruktionen. Arbetet har bestått av konceptgenerering för att finna omkonstruktionsmöjligheter av bäraren med värmespridare i form av grafit. Dessutom har konstruktionsanalyser genomförts genom praktiska prov och datasimuleringar. Testerna var framtagna för att jämföra grafit med olika värmeledningstal i olika riktningar samt undersöka hur grafiten påverkas av fuktig miljö. Simuleringarna gjordes för att utvärdera vilken påverkan de anisotropiska egenskaperna har vid olika tjocklekar på värmespridare av grafit. Resultatet var att den låga värmeledningsförmågan genom tjockleken påverkar mer vid ökad tjocklek. Att öka värmeledningen genom tjockleken på bekostnad av lägre värmeledning i planet sänkte inte temperaturskillnaderna i dessa tester. Grafiten påverkas i viss utsträckning av fukt och behöver därför inkapslas för att skyddas. Vid kylning av varma punkter s.k. ”hot spots” påverkar de anisotropiska egenskaperna mer än vid utbredd värmefördelning. Arbetet har resulterat i förslag på hur grafiten kan användas för omkonstruktion av bäraren och resonemang om miljökrav. Genom att använda grafit i olika konstruktionskonfigurationer kan temperaturen sänkas och/eller vikten minskas.

Full textIn commercial lithium ion batteries graphite is often used in the anode material, mainly because it can reversibly contain lithium ions between the layers. However, graphite has a limited energy density and research is therefore being performed to find methods that will increase the energy density of the anode material. Silicon, which has a significantly higher energy density, can be intercalated in the graphite to increase the energy density. However, in order to avoid a destructive volume expansion that occurs during the lithiation, the intercalation must be performed with silicon nanoparticles. A scalable method for producing silicon nanoparticles on nanographite flakes has been developed and presented in an article by Phadatare et al. The purpose behind this work has been to lay the foundation for large-scale production of silicon- based anodes intended to be used in lithium-ion batteries to provide them with increased capacity. The aim of the work was to present whether the method is repeatable and how different parameters affect the results for an upscaling, which was done through laboratory investigations. The results confirmed that the method presented in the article is repeatable and that the process should be carried out using a tube furnace. The results also showed that the temperature of the oven process should not be lowered to 600 °C, but that there is potential to lower it from the current 800 °C. At the current temperature, the percentage of silicon should not be increased to ≥ 47 %, but is considered to have the potential to be increased from the current 33 %. Only a small proportion of silicon nanoparticles was formed when a silicon powder of a different quality than that described in the article was used and showed that the choice of the silicon starting material is of great importance. The results further revealed that the dispersant polyvinyl alcohol, PVA, cannot be excluded. The results showed that there is potential to reduce the proportion of PVA, but that it should not be reduced to as much as half the concentration that is presented in the article. The results showed that the process must be carried out in an oxygen-poor environment in order not to cause oxidation of the nanographite. However, the results also indicated that the mechanism for the formation of silicon nanoparticles is not oxygen sensitive and that the mechanism, if the existing theory is correct, does not appear to be dependent on PVA beeing the source of hydrogen.

Full textGraphene is a material that is growing in popularity and recognition and is believed to have just at great potential in changing the world of production as plastic had. Pegil Innovations AB have, in collaboration with 2D fab, developed a machine prototype that expands graphiteusing microwave technology. To expand graphite is an early step in the process of producing graphene according to 2D fab’s method. This thesis work has been carried out at the University of Skövde on behalf of Pegil Innovations AB with the purpose of developing the design of the machine prototype they currently hold.A pilot study was completed early in the process about relevant information regarding what graphene is, how the machine prototype and its different components work as well as usability, sustainability and ergonomics. After the pilot study, a more in-depth study of literature was carried out over graphene production, redesign of other products and safety within the manufacturing industry. This work, together with the user studies, resulted in a list of requirements where one of the main objectives was to redesign the machine in a way so that it would not contain any rotating parts where the microwave radiation takes place. Methods that were used during the concept development involved brainstorming, ideation sketching and a morphological matrix. This resulted in five concepts that were evaluated together with the chief of production at Pegil as well as the technical advisor at 2D fab. After further development of the concepts, a concept weighing matrix was completed in order to choose a final concept to continue working with. The thesis work resulted in a concept suggestion that fulfills Pegils request of non-moving parts. The concept contains new components such as a vertical screw transporter that enables a much lower height for refilling the container than the current machine prototype. The concept follows the design preferences established in the design format analysis and fulfills the requirements in the list of requirements.Finally, results and suggestions for continued work on the machine concept are discussed.
