We consider planar networks of Euler-Bernoulli beams subject to Neumanntype boundary controls at simple nodes. The object is to minimize a cost functional along some part of the beam structure by theâ€¦ (More)

A new method for the efficient solution of free material optimization problems is introduced. The method extends the sequential convex programming (SCP) concept to a class of optimization problemsâ€¦ (More)

The design of auxetic structures is traditionally based on engineering experience, see, for instance, refs. [1,2]. The goal of this article is to demonstrate how an existing auxetic structure can beâ€¦ (More)

We consider second order problems on metric graphs under given boundary and nodal conditions. We consider the problem of changing the topology of the underlying graph in that we replace a multipleâ€¦ (More)

In this paper we consider some classes of discrete- continuous 2-D models in order to build a finite dimensional linear state space model of a gas distribution network. The models introduced areâ€¦ (More)

We consider models based on conservation laws. For the optimization of such systems, a sensitivity analysis is essential to determine how changes in the decision variables influence the objectiveâ€¦ (More)

We consider dynamical systems under feedback with control actions limited to switching. We wish to understand the closed-loop systems as approximating multi-scale problems in which the implementationâ€¦ (More)

In many bio-molecular and nano-technological processes, the physical phenomenon of Brownian motion plays an important role. At this, nano-sized particles suspended in a fluid move in a random mannerâ€¦ (More)

For p = 2, only few results about analytic solutions of problems of optimal control of distributed parameter systems with minimal Lpâ€“norm have been reported in the literature. In this paper weâ€¦ (More)
