A polynomial approach is pursued for locally stabilizing discrete-time linear systems subject to input constraints. Using the Youla-Ku cera parametrization and the extended Farkas lemma, the problem of guaranteeing closed-loop stability for any initial condition chosen in a given polyhedron of the state-space is formulated as a linear programming feasibility problem. This paper, as the rst of a...

This article examines worker-client relationships in hairstyling. Data is drawn from interviews with 15 hourly-paid and 32 selfemployed hairstylists and a self-administered survey. Relations of employment are found to be central to the deployment of emotional labour. Self-employed owner-operators are highly dependent on clients, rely on deep-acting, enact favours, and are prone to emotional bre...

In this paper, we show how to use the theory of fractional ideals in order to study the fractional representation approach to analysis and synthesis problems for SISO systems. Within this mathematical framework, we give necessary and su8cient conditions so that a plant is internally/strongly/bistably stabilizable or admits a (weak) coprime factorization. Moreover, we show how to generalize the ...
