2. Strong L1 convergence to equilibrium without entropy conditions for the spatially homogenous Boltzmann equation
Sammanfattning : This paper deals with solutions to the Cauchy problem for the spatially homogeneous non-linear Boltzmann equation. The main result is that for the hard sphere kernel, a solution to the Boltzmann equation converges strongly in L1 to equilibrium given that the initial data f0 belongs to L1(R^3;(1+v^2)dv). LÄS MER
3. Improving the functionality of synchronous machines using power electronics
Sammanfattning : With the advent of modern power electronics there is reason to explore what can be achieved when it is applied to a mature technology like synchronous machines. In this text several concepts will be presented on how it is possible to control forces and how to get better performance out of synchronous machines by using power electronics. LÄS MER
4. Framtidens arbete i den digitala och gröna omställningen : Förändring och stabilisering
Sammanfattning : This dissertation focuses on the construction of future steel work and work environment in relation to the ongoing digital and green transitions. The transitions include a clear focus on technology and has so far been lacking a focus on work. LÄS MER
5. Logistics management operationalised in a healthcare context : Understanding care chain effectiveness through logistics management theories and systems theory
Sammanfattning : Healthcare improvements is constantly relevant and an important topic. Healthcare is frequently being called upon to be more cost-efficient and still fulfil demands regarding waiting times, quality and availability. LÄS MER
