This report is a description of a developed educational simulator over rail vehicles and its components. The simulator is a hardware-based prototype over a door system on rail vehi- cles. System specialists and technicians will use the prototype. The Simulator should give the user a technical demonstration on how components work in a door system. The proto- type consists of motor, switch, relay and sensor.

This study takes its starting point in ongoing changes and differences in the global power dynamics. The liberal rules-based world order that has been acknowledged for governing the world with the US as the hegemon of power has been strongly challenged during the last decades. Russia?s invasion of Ukraine can be seen as an example of ongoing changes in the world order, with Russia as a challenger to the US as the hegemon of power. The changes and instability that this has led to for Sweden's national security situation can be seen as a concrete example of how ongoing changes in the world order affect Sweden?s foreign policy.

I denna uppsats g?rs en deskriptiv och j?mf?rande analys av olika partif?retr?dares s?kerhetspolitiska problemdefinitioner i en specifik riksdagsdebatt som avh?lls i januari 2015. Problem: Unders?kningen utg?r fr?n att uppfattningen om vad som utg?r ett samh?llsproblem ? i detta fall s?kerhetspolitiska problem - och vad detta n?rmare best?r i inte ?r n?gon sj?lvklarhet, utan n?got som formas av en st?ndigt p?g?ende debatt och diskussion i vad som kan liknas vid en kampartad kollektiv definieringsprocess d?r olika akt?rer str?var efter att etablera just sin verklighetsuppfattning som dominerande. Med denna utg?ngspunkt kan samh?llsproblem av olika slag betraktas som sociala konstruktioner.
