Human-induced climate change presents grave challenges to society. We have to find ways both to mitigate the changes and adapt to them. However, this is not all, for politics climate change represents a problem with large scientific uncertainties. This is evident in the Intergovernmental Panel on Climate Change (IPCC) assessment reports. In this study, scientific uncertainty is discussed and syste
The optimum-seeking (in the sense of maximisation of torque) field weakening control scheme proposed by Kim and Sul (see IEEE Trans. Ind. Electron., vol. 44, no.4, p.512-18, 1997) is developed further. The performance under imperfect field orientation conditions is investigated, and it is shown that an overestimated-rather than an under-estimated-model leakage inductance should be used. A slightly
What happens when global market-oriented models for auditing and quality assessment are taken up by local parishes? The paper is based on case studies where a number of parishes and auditing models provide the object of study. Parishes are to some extent restrictive about embracing new ideas on auditing and quality control. With assistance from neo-institutional theory it can be shown that the co
The dual control problem for time-varying or non-linear systems is inherently analytically and computationally untractable due to the demand of alternating minimizations and mean value computations. Hence, it has to be approached using approximations leading to suboptimal dual control. The core of the successful approximative controller is its ability to be able to consider future changes in the d
Since 1970s the development and introduction of heat pumps have been supported as a strategy to improve energy efficiency in Sweden and Switzerland. Several policy instruments have been applied, such as R&D, subsidies/electricity price incentives, labelling and quality test centres. The justification of introducing heat pumps as an energy-efficient end use technology was, in general, to decrea
The aim of this report is to give an overview on previous research on HMI, relevant for the concept of “Safe Speed and Safe Distance”. The review of the literature shows that providing the driver with relevant, timely information is of paramount importance. The ideal HMI system gives the driver concise but comprehensive timely information allowing him/her sufficient time for reading and understan
