ISO 26262 requires a controllability assessment for the hazard and risk analysis of automotive E/E systems. Depending on the verifiable controllability, a function may be limited in terms of its intervention options and intensity. For Active Safety Systems this limits their accident-avoidance/-mitigation potential. An analysis of the applicability of ISO 26262 for these systems reveals that it ...

INTRODUCTION The purpose of this study was to investigate whether attribution theory could explain speech-language pathologists (SLPs) perceptions of children with communication disorders such as stuttering. Specifically, it was determined whether perceptions of onset and offset controllability, as well as biological and non-biological attributions for communication disorders were related to wi...

We examine the role of structural autapses, when a neuron synapses onto itself, in driving network-wide bursting behavior. Using a simple spiking model of neuronal activity, we study how autaptic connections affect activity patterns, and evaluate if controllability significantly affects changes in bursting from autaptic connections. Adding more autaptic connections to excitatory neurons increas...

Quantum phenomena of interest in connection with quantum computation and communication often deal with transfers between eigenstates, and their linear superpositions. For systems having only a finite number of states, the quantum evolution equation (the Schrödinger equation) is finite-dimensional and the results on controllability on Lie groups as worked out decades ago [1] provide most of what...

Abstract. In this paper, the existence and uniqueness of mild solution is initially obtained by use of measure of noncompactness and simple growth conditions. Then the conditions for approximate controllability are investigated for the distributed second-order neutral stochastic differential system with respect to the approximate controllability of the corresponding linear system in a Hilbert s...

Major advances have been made recently towards understanding how to control large networks by acting only on a small subset of their elements, illuminating the impact of a network’s topology on its controllability. Yet, a detailed understanding of the synergies between network topology and intrinsic individual dynamics is still lacking. Here we offer a theoretical framework to evaluate the cont...

We study the controllability of linear distributed control systems described by differential equations in Banach spaces with a degenerate operator at the derivative. A homogeneous part of equations has a degenerate strongly continuous resolving semigroup. For such system with, generally speaking, a time-dependent bounded operator at the control function we find the criteria of ε-controllability...

This paper proposes a new method for assessing the vulnerability of power systems based on the controllability theories of complex networks. A novel controllability index is established, taking into consideration the full controllability of the power systems, for identifying critical nodes. The network controllability model is used to calculate the minimum number of driver nodes (ND), which can...

We consider the problem of exact controllability of the wave equation with Dirichlet boundary conditions and multiplicative controls. A multiplicative control is a coeffi cient like uy. Exact controllability result is stated and proved for some particular targets.

In this article, we study the controllability of impulsive functional differential equations with nonlocal conditions. We establish sufficient conditions for controllability, via the measure of noncompactness and Mönch fixed point theorem.
