Objective evaluation model of sewing flatness based on deep belief network
In view of the low accuracy of objective automatic evaluation of fabric sewing flatness, an objective evaluation model of fabric sewing flatness based on feature parameters and deep belief network (DBN) is proposed. Firstly, image preprocessing including

In-domain control of a heat equation: an approach combining zero-dynamics inverse and differential flatness [PDF]
This paper addresses the set-point control problem of a heat equation with in-domain actuation. The proposed scheme is based on the framework of zero dynamics inverse combined with flat system control.

Flatness-Based High Frequency Control of a Hydraulic Actuator [PDF]
This paper presents the design and implementation of a nonlinear feedforward control algorithm for a hydraulic actuator driven by a multistage servo valve. Combined with a conventional feedback control algorithm, high frequencies can be achieved even for large-scale strokes.

Accuracy of Surface Plate Measurements - General Purpose Software for Flatness Measurement [PDF]
Flatness departures of surface plates are generally obtained from straightness measurements of lines on the surface. A computer program has been developed for on-line measurement and evaluation, based on the simultaneous coupling of measurements in all ...

Real-Time Trajectory Planning and Control for Constrained UAV Based on Differential Flatness
The trajectory planning of UAV with nonholonomic constraints is usually taken as differential algebraic equation to solve the optimal control problem of functional extremum under the condition of inequality constraints.

Turbulence Analysis Of An Experimental Flux-Rope Plasma [PDF]
We have previously generated elongated Taylor double-helix flux-rope plasmas in the SSX MHD wind tunnel. These plasmas are remarkable in their rapid relaxation (about one Alfven time) and their description by simple analytical Taylor force-free theory ...
