This paper provides a theoretical overview of the public-private partnerships for policy and concept development. We use a case study from Sweden of a road user charging development prject to explore institutional barriers to PPPs and to describe how a more informal co-operation not only brings added value to the project but also enables an ongoing innovation process which we hope will result in r
There are to be sure many reasons for studying Axel Oxenstierna’s correspondence. One is the open pictures you get of prominent contemporaries, and the fact that the judgements and reports you read can be free from wisdom after the event. You have thus an excellent opportunity to get a glimpse of the background to the initiatives and actions of those at the centre of power. In my paper I will di
We consider differential Riccati equations (DREs). These equations arise in many areas and are very important within the field of optimal control. In particular, DREs provide the crucial link between the state and the optimal input in the solution of linear quadratic regulator (LQR) problems. For the approximation of the solutions to DREs we consider the recently introduced splitting methods, wit
This study takes its starting point in the questions of whether and how theology might serve as a faith-based peacebuilding resource. Based on an exploration of the textual process towards an international ecumenical declaration on just peace in the World Council of Churches, it suggests that theology can indeed serve as such a resource and it sketches how theology can make such a contribution. Th
This paper concerns the estimation of MIMO capacity in a given propagation environment from the magnitude patterns of multiple antennas. In our previous contribution, we presented a simple approach of synthesizing phase on the magnitude patterns by taken into account the antenna separation. Although this approach works well even when the antenna separation is small and the signal correlation is hi
Simmons (1990) has introduced an extended authentication model where caution is taken both against deceptions from an outsider (opponent) and against some forms of deception from the insiders (transmitter and receiver). Codes for this model are called authentication codes with arbitration, or simply A2 codes. A new construction of authentication codes with arbitration is proposed, which uses codes
