We describe, in this paper, a new digital inputoutput power configurable PAD (CPAD) for a wafer-scale-based rapid prototyping platform for electronic systems. This waferscale platform includes a reconfigurable wafer-scale circuit that can interconnect any digital components manually deposited on its active alignment-insensitive surface. The whole platform is powered using a massive grid of embe...

This study examined the role of output-first presentation of vocabulary tasks in noticing lexical items and enhancing vocabulary knowledge of EFL learners. The participants were 103 elementary level female Iranian EFL learners who were randomly divided into three groups: input-only, inputoutput, and output-input groups. After all participants took a placement test and a vocabulary pretest, the ...

A metamodel in simulation modeling, as also known as response surfaces, emulators, auxiliary models, etc. relates a simulation model’s outputs to its inputs without the need for further experimentation. A metamodel is essentially a regression model and mostly known as “the model of a simulation model”. A metamodel may be used for Validation and Verification, sensitivity or what-if analysis, and...

This paper develops a state-space theory for the study of linear shift-invariant finite-dimensional hybrid dynamical systems. By hybrid system, we mean an inputoutput operator relating hybrid signals, that is, signals which consist of two parts: a continuous-time part and a discrete-time part. We first introduce the hybrid state-space model and show the closedness properties under the fundament...

This contribution reviews theory, algorithms, and validation results for system identification of continuous-time state-space models from finite inputoutput sequences. The algorithms developed are autoregressive methods, methods of subspace-based model identification and stochastic realization adapted to the continuous-time context. The resulting model can be decomposed into an input-output mod...

Controlling an underactuated manipulator with less actuators than degrees of freedom is a challenging problem, specifically when it is to force the underactuated manipulator to track a given trajectory or to be configurated at a specific position in the work space. This paper presents two controllers for the set point regulation of 2-DOF underactuated manipulators. The first one is a cascade sl...

Assimilation of spatiallyand temporally-distributed state observations into simulations of dynamical systems stemming from discretized PDEs leads to inverse problems with high-dimensional control spaces in the form of discretized initial conditions. Solution of such inverse problems in “real-time” is often intractable. This motivates the construction of reduced-order models that can be used as ...

Zusammenfassung Der Beitrag beschreibt eine exakte E/ALinearisierung für die translatorische Dynamik eines Quadrocopters. Die hierfür relevante Lageinformation reduziert sich auf die Ausrichtung des Schubvektors (bzw. der körperfesten zAchse), welche mit zwei Freiheitsgraden beschrieben werden kann. Hierzu wird im vorliegenden Beitrag ein spezielles Schubachsenquaternion eingeführt. Die E/A-Lin...

Zusammenfassung Dieser Beitrag behandelt den Entwurf von Folgereglern für nichtlineare Eingrößensysteme mittels linearer zeitvarianter dynamischer Ausgangsrückführung, die anhand der Linearisierung der Strecke um die Solltrajektorie bestimmt wird. Der Folgeregler besteht aus einem reduzierten Beobachter zur Rekonstruktion der Stellsignale einer linearen zeitvarianten Zustandsrückführung, welche...

Control contact systems represent controlled (or open) irreversible processes which allow to represent simultaneously the energy conservation and the irreversible creation of entropy. Such systems systematically arise in models established in Chemical Engineering. The differential-geometric of these systems is a contact form in the same manner as the symplectic 2-form is associated to Hamiltoni...
