Norm Monitoring under Partial Action Observability
In the context of using norms for controlling multi-agent systems, a vitally
important question that has not yet been addressed in the literature is the
development of mechanisms for monitoring norm compliance under partial action
observability. This paper proposes the reconstruction of unobserved actions to
tackle this problem. In particular, we formalise the problem of reconstructing
unobserved actions, and propose an information model and algorithms for
monitoring norms under partial action observability using two different
processes for reconstructing unobserved actions. Our evaluation shows that
reconstructing unobserved actions increases significantly the number of norm
violations and fulfilments detected.Comment: Accepted at the IEEE Transaction on Cybernetic
optimization of multiple tuned mass dampers for multimodal vibration control
In this paper, a new computational method for the purpose of multimodal
vibration mitigation using multiple tuned mass dampers is proposed.
Classically, the minimization of the maximum amplitude is carried out using
direct optimization. However, as shall be shown in the paper, this
approach is prone to being trapped in local minima, in view of the nonsmooth
character of the problem at hand. This is why this paper presents an original
alternative to this approach through norm-homotopy optimization. This approach,
combined with an efficient technique to compute the structural response, is
shown to outperform direct optimization in terms of speed and
performance. Essentially, the outcome of the algorithm leads to the concept of
all-equal-peak design for which all the controlled peaks are equal in
amplitude. This unique design is new with respect to the existing body of
knowledge.Comment: This is a new version of a preprint previously named "All-equal-peak
