Temporal logics with incommensurable distances are undecidable
Temporal logic based on the two modalities “Since” and “Until” (TL) is the most popular logic for the specification of reactive systems. It is often called the linear tim...

Performance bounds in linear control of unstable MIMO systems with pole location constraint
This paper proposes a methodology to compute quadratic performance bounds when the closed loop poles of a discrete-time multivariable control loop are confined to a disk, centred ...

Criticality of lateral inhibition for edge enhancement in neural systems
Although the role of lateral inhibition in edge (contrast) enhancement is well known, it has not been parametrized. This paper investigates the imbalance between the lateral inhib...

Problems on time-varying port-controlled Hamiltonian systems: geometric structure and dissipative realization
To apply time-varying port-controlled Hamiltonian (PCH) systems to practical control designs, two basic problems should be dealt with: one is how to provide such time-varying syst...
