In total 6 empirical case studies and interviews with different stakeholders are employed in the research. This thesis argues that the govern

This master thesis was conducted as a project for Faiveley Transport Nordic AB. The company’s main operations are development and assembly of complete brake solutions, brake products, wheels and couplings for rail vehicles. The background of this project was a well thought out idea of a new generation of friction brakes. The idea of V-brake is to complement or replace the block brake. A problem wi

In this project, the several steps in a product development process can be followed, from the first brainstorming of basic concepts to the final implementation of the manufactured product in the factory. The project was assigned by Faiveley Transport Nordic AB and its aim was to design a well functioning test rig for testing of their train brake units. The new rig’s advantages compared to old exi

The interactions between airway epithelial cells (AECs) and dendritic cells (DCs) play an important role in the sensitization towards airborne allergens. Not much is known about the underlying mechanisms and novel in vitro approaches are needed, which include the different involved cell types in order to investigate what happens at the molecular level during sensitization. In this project, one aim

The investigation covers how water affects the selectivity to the main product a

In modern batch plants, alarm floods overwhelming the operator is a common problem of ever increasing severity. As plant hardware increase in complexity and performance, measures such as downtime and meantime between failures, increase in importance and the need for a well-functioning exception handling routine therefore grows critical. In order to minimize downtime and hence boost production effi

In 2011, China’s urban population surpassed its rural population for the first time in the history when it reached 690 million. The massive urbanization has resulted in a booming of urban housing and infrastructure. Consequently, crowded infrastructure systems burdened by an increasing urban population and severe environmental problems like air pollution have become the main challenges for Chinese

Problem: Under de senaste 50 åren har människan konsumerat mer än alla generationer tillsammans. En motreaktion har utvecklats mot det stereotypa ”du är vad du konsumerar eller äger”, vilket benämns som the sharing economy. Grundtanken är att dela på sina resurser för att använda dessa fullt ut. Fenomenet är relativt nytt, men har under de senaste åren haft stor inverkan på resenärers förändrade b
