Geometrical Modeling of Steel Ropes

Liquid ropes: a geometrical model for thin viscous jet instabilities.

Thin, viscous fluid threads falling onto a moving belt behave in a way reminiscent of a sewing machine, generating a rich variety of periodic stitchlike patterns including meanders, W patterns, alternating loops, and translated coiling. These patterns form to accommodate the difference between the belt speed and the terminal velocity at which the falling thread strikes the belt. Using direct nu...

Application of Wavelet Methods to Magnetic Testing of Steel Ropes

The paper refers to problems related to processing of non-stationary signals. The signals originated from non-destructive testing of steel ropes using a magnetic method, where non-stationary features are related to presence in the signal of an impulse component. This component can be a symptom of a failure and its proper identification is necessary while estimation of a rope's wear and tear. Cl...

Deep-learning the Ropes: Modeling Idiomaticity with Neural Networks

English. In this work we explore the possibility of training a neural network to classify and rank idiomatic expressions under constraints of data scarcity. We discuss our results comparing them both to other unsupervised models designed to perform idiom detection and to similar supervised classifiers trained to detect metaphoric bigrams. Italiano. In questo lavoro esploriamo la possibilità di ...

Numerical and Experimental Study of Geometrical Dimensions on Laser-TIG Hybrid Welding of Stainless Steel 1.4418

In this paper, a three-dimensional finite element model has been developed to simulate the laser-TIG hybrid welding (HLAW) of stainless steel 1.4418 with thickness of 4 mm. Transient temperature profile and dimensions of the fusion zone and heat affected zone (HAZ) during welding process are calculatedusing finite element method (FEM) and were solved in the ABAQUS/Standard software.The heat sou...
