Dynamic Input/Output Automata: a Formal and Compositional Model for Dynamic Systems [PDF]

open access: yes, 2016
We present dynamic I/O automata (DIOA), a compositional model of dynamic systems. In DIOA, automata can be created and destroyed dynamically, as computation proceeds, and an automaton can dynamically change its signature, i.e., the set of actions in ...

Research on Modeling of a Micro Variable-Pitch Turboprop Engine Based on Rig Test Data

open access: yesEnergies, 2020
Exact component characteristics are required for establishing an accurate component level aeroengine model. When component characteristics is lacking, the dynamic coefficient method based on test data, is suitable for establishing a single-input and ...

An Achievable Rate for the MIMO Individual Channel [PDF]

open access: yes, 2010
We consider the problem of communicating over a multiple-input multiple-output (MIMO) real valued channel for which no mathematical model is specified, and achievable rates are given as a function of the channel input and output sequences known a ...

A PRODUCTIVITY EVALUATION MODEL BASED ON INPUT AND OUTPUT ORIENTATIONS

open access: yesSouth African Journal of Industrial Engineering, 2012
<p>ENGLISH ABSTRACT: Many productivity models evaluate either the input or the output performances using standalone techniques. This sometimes gives divergent views of the same system’s results.

Input-Output Economics and Material Flows [PDF]

open access: yes
This paper argues that resources constitute the fundamental area of overlap between the interests of input-output economists and industrial ecologists. Three misconceptions about input-output economics obscure this fact: the frequent failure to utilize ...

Backstepping control for a 3DOF model helicopter with input and output constraints

open access: yesInternational Journal of Advanced Robotic Systems, 2016
In this article, a backstepping control scheme is developed for the motion control of a Three degrees of freedom (3DOF) model helicopter with unknown external disturbance, modelling uncertainties and input and output constraints.
