Modelización de los procesos de conformado en caliente de los aceros microaleados de medio carbono mediante la aplicación de redes neuronales artificiales

Alcelay Larrión, José Ignacio (Date of defense: 2015-09-10)

In this thesis a study was performed to obtain a model of artificial neural network that is able to predict the flow behavior of steel under hot deformation conditions. The hot compression tests are performed on two types ...

Solving the nearest rotation matrix problem in three and four dimensions with applications in robotics

Sarabandi, Soheil (Date of defense: 2021-04-27)

Since the map from quaternions to rotation matrices is a 2-to-1 covering map, this map cannot be smoothly inverted. As a consequence, it is sometimes erroneously assumed that all inversions should necessarily contain ...
