Induction Machine Broken-Bar Fault Diagnosis Using the Rotor Magnetic Field Space-Vector Orientation
A new technique based on rotor magnetic field space vector orientation is presented to diagnose broken-bar faults in induction machines operating at steady state. In this technique, stator currents and voltages are used as inputs to compute and subsequently observe the rotor magnetic field orientation, which has a more significant "swing-like ...

ORIENTATION MODELING FOR AMATEUR CAMERAS BY MATCHING IMAGE LINE FEATURES AND BUILDING VECTOR DATA [PDF]
With the popularity of geospatial applications, database updating is getting important due to the environmental changes over time. Imagery provides a lower cost and efficient way to update the database.

On the orientation of the pulsar space velocity vector relative to the spin axis [PDF]
A SIGNIFICANT parameter for pulsars for which proper motion data are available is the angle φ between the space velocity vector and the spin axis. There are eleven such pulsars (ref. 15 and personal communication from one of the authors). The angle between the spin axis projected on the plane of the sky and the proper motion vector has a value close to

In this paper, a classification algorithm of parking space images is proposed to improve the accuracy of parking space classification, which can be used in smart parking management systems based on video surveillance. The descriptors of a parking space image are formed on the basis of a histogram of oriented gradients by performing the following steps:

IMAGE ORIENTATION BY EMBEDDING IN A GAN LATENT SPACE [PDF]
Estimation of an image exterior orientation is required in multiple tasks including 3D reconstruction, autonomous driving and navigation, and single-photo 3D reconstruction. The problem can be easily solved if some reference points (keypoints) with known

Hierarchies over Vector Space: Orienting Word and Graph Embeddings
Word and graph embeddings are widely used in deep learning applications. We present a data structure that captures inherent hierarchical properties from an unordered flat embedding space, particularly a sense of direction between pairs of entities. Inspired by the notion of \textit{distributional generality}, our algorithm constructs an arborescence (a
