Analysis of Velocity Encoded Images --- With Applications in Cardiac MRI

The topic of the thesis is the analysis of velocity encoded medical images, acquired using magnetic resonance imaging or other means. The application in mind is to use such data to determine the motion and deformation of the human heart, which is of clinical and physiological interest. As the velocity measurements are noisy and degraded, an important issue is the regularization of the measurements

A general approach for deriving bounds in electromagnetic theory

This paper reports on a systematic procedure for deriving physical bounds in electromagnetic theory. The approach is based on the holomorphic properties of certain Herglotz functions and their asymptotic expansions in the low- and high-frequency regimes. A family of integral identities or summation rules is obtained with values governed by the coefficients in the low- and high-frequency expansions

Optimal Coordination of Homogeneous Agents Subject to Delayed Information Exchange

We consider a class of large scale linear-quadratic coordination problems where the information exchange is subject to a time-delay. We show that several previously known properties of the optimal solution to the delay-free problem extend to this case. In particular, the optimal control law comprises a diagonal (decentralized) term complemented by a rank-one coordination term, which can be impleme

Motifs of Anointing in the Old Testament and in John

While several scholars do not consider the anointing of (the feet of) Jesus in Bethany described in the Gospel of John to carry any messianic connotations, some claim that a royal messianic notion is behind the anointing. The hypothesis of this paper is that the anointing is indeed to be understood as messianic, but that it is insufficient to consider only one Christological motif to be in the bac
