We explore different approaches to modelling external choice as a reactive process in a UTP semantics with discrete time. The standard definition of external choice can not be simply reused in a timed semantics, since it can introduces behaviours which are not prefix-closed and urgent events which occur instantly. We first examine unstable states and urgent events in different semantics for CSP...
We investigate the response to an external magnetic field in the Hamiltonian mean-field model, which is a paradigmatic toy model of a ferromagnetic body and consists of plane rotators like XY spins. Due to long-range interactions, the external field drives the system to a long-lasting quasistationary state before reaching thermal equilibrium, and the susceptibility tensor obtained in the quasis...
We consider the effect of microscopic external noise on the collective motion of a globally coupled map in fully desynchronized states. Without the external noise a macroscopic variable shows highdimensional chaos distinguishable from random motions. With the increase of external noise intensity, the collective motion is successively simplified. The number of effective degrees of freedom in the...
BACKGROUND In 1998, a UNICEF report quantified the large East-West gap in Europe in child mortality from external causes (injuries and violence). In the past decade, much has changed in central and eastern Europe, economically, politically and socially. This study updates the earlier analysis, tracking changes in deaths from external causes in the different parts of Europe. METHODS The WHO mo...
Piezoelectric actuators are widely used for precise micro-positioning. In most applications, there is contact with the environment. Sensing external forces is a challenging problem in controlling mechanical systems, especially in micro scales. The external force could cause dual hysteresis non-linearity effects, which will disrupt the actuator positioning accuracy. Therefore, an effective contr...
The behavioral dynamics of a cognitive agent can be considered both from an external and an internal perspective. From the external perspective, behavior is described by specifying (temporal) correlations between input and output states of the agent. From the internal perspective the agent’s dynamics can be characterized by direct (causal) temporal relations between internal, mental states of t...
In this work we present an evolving system of agents which interact with each other in game theoretic settings. The parameters of the game are considered as time dependent variables representing state of the external environment. The variation of these parameters covers four canonical examples from game theory: prisoners dilemma, hawk-dove, stag-hunt and harmony game. The process of selfadaptat...
This paper aims to develop a boundary control solution for a single-link gantry robot manipulator with one axis of rotation. The control procedure is considered with link’s transverse vibrations while system undergoes rigid body nonlinear large rotation and translation. Initially, based on Hamilton principle, governing equations of hybrid motions as a set of partial differential equations...
Success of national institutions of quality assessment (NIQA) and accreditation of quality depends on the external quality assurance (EQA) processes. In spite of the fact, it is more than two decades that continuous quality assessment started in higher education in Iran. Nevertheless, the external in higher education quality assessment (non-medical), has not been done in an organized way yet. A...
Rapid and smooth reactive power compensation is crucial to maintain safe and reliable operation of power systems. This paper presents an adaptive and faulttolerant control (FTC) approach for reactive power compensation via a three-level cascaded STATCOM (static synchronous compensator). Two sets of FTC algorithms are derived to concurrently accommodate element/actuation faults, modeling uncerta...
