Application of convolutional neural networks for prediction of strip flatness in tandem cold rolling process

Journal of Manufacturing Processes, 2021
The problems of the strip flatness defects are always severe in the tandem cold rolling process. It is of great significance to predict flatness for flatness control according to the process conditions of products.

Analysis of lateral metal flow-induced flatness deviations of rolled steel strip: Mathematical modeling and simulation experiments

open access: yesApplied Mathematical Modelling, 2020
Geometric dissimilarity between the thickness profile of the entry strip and the deformed roll gap is the main cause of flatness defects. However, the combination of the crown ratio and the lateral metal flow complicates the flatness defect mode, making ...

Quantifying nonstabilizerness through entanglement spectrum flatness

Physical Review A, 2023
Non-stabilizerness - also colloquially referred to as magic - is the a resource for advantage in quantum computing and lies in the access to non-Clifford operations. Developing a comprehensive understanding of how non-stabilizerness can be quantified and

Data Augmented Flatness-aware Gradient Projection for Continual Learning

IEEE International Conference on Computer Vision, 2023
The goal of continual learning (CL) is to continuously learn new tasks without forgetting previously learned old tasks. To alleviate catastrophic forgetting, gradient projection based CL methods require that the gradient updates of new tasks are ...

Optimal flatness placement of sensors and actuators for controlling chaotic systems.

Chaos, 2021
Controlling chaotic systems is very often investigated by using empirical laws, without taking advantage of the structure of the governing equations. There are two concepts, observability and controllability, which are inherited from control theory, for ...

Terrestrial laser scanning assisted flatness quality assessment for two different types of concrete surfaces

Measurement: Journal of the International Measurement Confederation, 2020
Terrestrial laser scanning (TLS) that can acquire reliable scanned data with high-precision, has been popularly adopted for the flatness quality assessment (FQA) in civil engineering.

Flat Arbiters

Fundamenta Informaticae, 2009
A new way of constructing N-way arbiters is proposed. The main idea is to perform arbitrations between all pairs of requests, and then make decision on what grant to issue based on their outcomes. Crucially, all the mutual exclusion elements in such an arbiter work in parallel. This ‘flat’ arbitration is prone to new threats such as formation of cycles
