För att kunna utföra simuleringar och beräkningar på gummikomponenter behövs matematiska modeller som beskriver responsen för gummi vid olika typer av belastningar. Dessa modeller innehåller materialkonstanter, och dessa tas fram med hjälp av experimentella tester. I dagsläget görs alltid en hårdhetstest på gummi för att klassificera hur hårt (eller mjukt) ett gummi är. Detta utförs genom att trToday rubber can be found in many different applications, such as vibration dampers, tyres, clothes and gaskets. Two different types of rubbers are used today, namely the natural rubber and synthetic rubber. Natural rubber is made of a milky substance called latex, which is obtained from special trees found in tropical countries. Synthetic rubber is also made from latex, but the latex is obtained

Amelogenin is a major constituent of enamel matrix protein that is responsible for the development of tooth enamel. Due to its self-assembly and physicochemical properties, amelogenin has been widely used as one of the natural biomaterials. Amelogenin, along with the other enamel matrix proteins have been known for its regenerative properties. The purpose of this project is to evaluate the enginee

Despite the increasing level and number of techniques deployed to generate more robust, better-producing microbial cell factories for production of chemicals, the number of products that reach commercial feasibility is still very low. Many hurdles come along the way as it has been observed that strains designed in the laboratory do not perform as expected in industrial-scale bioreactors. For insta

Seasonal Affective Disorder (SAD) is a disease that threatens 8% of the population in Sweden. It is a problem without a scientifically proven reason, but with a solution. From many different treatments such as medication and psychotherapy, light treatment is the most easily available solution that can be used against SAD. The current market for SAD lamps is bland and uninteresting. Through a pe

Gender inequality in sports is a serious issue that needs to be defeated. The imbalance between the genders occurs in everything from media publicity to salaries, access to facilities and branding. Fortunately, football among women is getting more popular day by day, which has created a need for football shoes designed for women. However, still today, football brands rely on a “pink it and shr

Cities of the world face complex challenges related to environmental resources. The good cultivation soil as today’s global resource becoming a scarce commodity. The demand for locally produced food is increasing, therefore growing food and crops in and near cities is and the connection between country and city is becoming increasingly important.

The thesis intends to find the different powertrain concepts on the state of the art. From the configurations, the thesis should provide outcomes of the performance, efficiency, complexity design and cost. Furthermore, the best concept should be find and a simple pre

De ekonomiska, logistiska och realpolitiska ramar som byggandet utgår ifrån är inte alltid en utgångspunkt i våra projekt som arkitekter. Istället möter de dessa ramar på vägen mot förverkligande, och tvingas omformas, ibland utan arkitektens medverkan, för att passera igenom. Tydligast märks kanske detta i bostadsbyggandet, en sektor där arkitekturen gränsar till ett politikområde med ideologiska

Wireless communication nowadays is playing a vital role in real-life data transmission. This communication can be machine-to-machine or human to machine communication. In each of these categories, reliability and low latency data transmission are critical factors of success transmission in case the number of devices in a certain area increases. In this thesis, I mainly investigate on smart manufac
