Unfortunately there is no documentation available on the performance achievable in closed-loop for each problem instance, such as for example the maximum stability margin or minimum H2 or H∞ norm. In the case of static state feedback or full-order 3 dynamic controller feedback, solving these design problems amounts at solving a numerical linear algebra problem, or at worst a quasi-convex optimi...

bivariate features, obtained from multichannel electroencephalogram (eeg) recordings, quantify the relation between different brain regions. studies based on bivariate features have shown optimistic results for tackling epileptic seizure prediction problem in patients suffering from refractory epilepsy. a new bivariate approach using univariate features is proposed here. differences and ratios ...

Fuzzy ideal set and fuzzy local function of fuzzy ideals with fuzzy topologies were introduced and studied by D. Sarker [10]. The purpose of this paper deals with new sort of fuzzy ideal and fuzzy local function namely fuzzy ideal and r-fuzzy open local function. Many of its characterizations, properties and connections between it and other corresponding fuzzy notions are studied. Also, we intr...

A (loopless) digraph H is strongly immersed in a digraph G if the vertices of H are mapped to distinct vertices of G, and the edges of H are mapped to directed paths joining the corresponding pairs of vertices of G, in such a way that the paths used are pairwise edge-disjoint, and do not pass through vertices of G that are images of vertices of H. A digraph has cutwidth at most k if its vertice...

In this letter, a generalization of pairwise models to non-Markovian epidemics on networks is presented. For the case of infectious periods of fixed length, the resulting pairwise model is a system of delay differential equations (DDE), which shows excellent agreement with results based on explicit stochastic simulations of non-Markovian epidemics on networks. Furthermore, we analytically compu...

In this paper, we obtain a canonical central element νH for each semisimple quasiHopf algebraH over an algebraically closed field of char 0 and prove that νH is invariant under gauge transformations. Moreover, if H is a semisimple Hopf algebra or a twisted quantum double of a finite group, then χ(νH) is the Frobenius-Schur Indicator of the irreducible representation which affords the character ...

We study the subgroup structure of discrete groups which share cohomological properties which resemble non-negative curvature. Examples include all Gromov hyperbolic groups. A subgroup H ⊂ G is called s-normal, if H∩H is infinite for all g ∈ G. We provide strong restrictions on the possible s-normal subgroups of a Gromov hyperbolic group, or more generally a ’negatively curved’ group. Another r...

The faithful quasi-dual H and strict quasi-dual H ′ of an infinite braided Hopf algebra H are introduced and it is proved that every strict quasi-dual H ′ is an HHopf module. The connection between the integrals and the maximal rational Hsubmodule H of H is found. That is, H ∼= ∫ l H ⊗H is proved. The existence and uniqueness of integrals for braided Hopf algebras in the Yetter-Drinfeld categor...

During the early history of unitary quantum theory Kato's exceptional points (EPs, a.k.a. non-Hermitian degeneracies) Hamiltonians $H(\lambda)$ did not play any significant role, mainly due to Stone theorem which firmly connected unitarity with Hermiticity. recent wave optimism people started believing that corridors a access EPs could be opened leading, say, new picture phase transitions via a...
