Clays were used as a template to produce graphene-like layers from sugar, a natural renewable resource. Raman spectroscopy showed that the synthesis with five times more sugar than clays produced multilayered graphene better ordered than when starting with a lower proportion of sugar. At 6.5 MPa, the clay graphene-like nanostructured materials are as conductive as commercially available graphene....
In this paper, we relax the modeling assumptions under which Bayesian filtering is tractable. In order to restore tractability, we adopt the stabilizing forgetting (SF) operator, which replaces the explicit time evolution model of Bayesian filtering. The principal contribution of the paper is to define a rich class of conditional observation models for which recursive, invariant, finite-dimensional...
The main focus of this paper is to extend Bayesian filtering to allow for time-variant parameters in the transition kernels. Since a finite-dimensional exact solution is not available, we adopt stabilized forgetting in order to restore a recursive signal processing algorithm in this case, involving the processing of fixed, finite-dimensional statistics. This approximate solution is amenable to online...
A microgrid is a controllable component of the smart grid defined as a part of distribution network capable of supplying its own local load even in the case of disconnection from the upstream network. Microgrids incorporate large amount of renewable and non-renewable distributed generation (DG) that are connected to the system either directly or by power electronics (PE) interface. The diversity of...
This paper presents a novel sectionalizing method for the build-up strategy in power system restoration. Power system restoration is the procedure of restoring power system elements after a partial or a complete blackout. Because of its economic and political importance, different strategies have been developed for power system restoration. One of the most practical and economical is the build-up...
Graphical structures (like graphs, diagrams, visual sentences and others) are very useful to describe complex structures and systems. These structures are often augmented by formalisms which add a further dimension to the static description allowing for the modeling of the evolution of systems via any kind of transformation of such graphical structures. Graph transformation has been widely used for...
