Controllability of sequential machines

open access: yesInformation and Control, 1972
A sequential machine is said to be k-controllable if there exists a minimum integer k such that every state transition can be achieved by an input sequence of length k. In this paper properties of controllable sequential machines are discussed. The main results are as follows: (1) An efficient procedure for controllability test is given.

Autonomous, Onboard Vision-Based Trash and Litter Detection in Low Altitude Aerial Images Collected by an Unmanned Aerial Vehicle

open access: yesRemote Sensing, 2021
Public littering and discarded trash are, despite the effort being put to limit it, still a serious ecological, aesthetic, and social problem. The problematic waste is usually localised and picked up by designated personnel, which is a tiresome, time ...

Efficient Shape Estimation of Transparent Microdefects with Manifold Learning and Regression on a Set of Saturated Images

open access: yesApplied Sciences, 2020
In the industry of polymer film products such as polarizers, measuring the three-dimensional (3D) contour of the transparent microdefects, the most common defects, can crucially affect what further treatment should be taken.

Hybrid modelling and simulation of a computer numerical control machine tool feed drive [PDF]

open access: yes, 2004
The paper presents a new approach to the modelling and simulation of a computer numerical control (CNC) machine tool feed drive. The hybrid model of the drive incorporates a distributed load, explicit damping factors and measured non-linear effects in ...

Right Harmonic Spectrum for the back-electromotive force of a n-phase synchronous motor [PDF]

open access: yes, 2004
This paper deals with a vector control of n-phase permanent magnet synchronous machine. To use control algorithms already developed for sine-wave 3-phase machines, the spectrum of back electromotive force (EMF) must contain only odd 2k+1 harmonics which ...

3D structure design of magnetic ferrite cores using gelcasting and pressure-less sintering process

open access: yesAIP Advances, 2019
Gelcasting is a well established process for ceramics manufacturing which recently has been proved to be successful for soft ferrites as well. This approach is particularly interesting for power electronics application in which the magnetic components (e.
