چکیده

Although intensive work has been devoted to Spatio-temporal (ST) qualitative reasoning models, some issues such as management of complex objects life and motion remain. First, ST histories’ clustering using a set of life and motion configurations is briefly presented. Then, we discuss a model based on the generalization of the life and motion configurations into a set of 25 relationships. These generalized configurations are assimilated to line-line topological relationships obtained by projecting life and motion configurations in a primitive space. Finally, interpretation of these generalized relationships in natural language is given.

Life and Motion Configurations: A Basis for Spatio-temporal Generalized Reasoning Model

Although intensive work has been devoted to spatio-temporal qualitative reasoning models, some issues such as management of complex objects life and motion remain. In this paper, we propose a model dealing with existence and presence of object concepts. First, we introduce spatio-temporal states, which express existing spatio-temporal relationships between two objects at a given time. Spatio-te...

Effects of Pitching Motion on Shock Behavior in a Body-Wrap Around Fin Configuration

Unsteady dynamic behavior of TTCP model with different wrap around fin sets were investigated in a trisonic wind tunne. The aerodynamic coefficient force measurement in this wind tunnel shows good agreement in comparison with that of the NASA Langley Research Center in static case. The model was sinusoidally oscillated at three different frequencies of 1, 3 and 8 Hz at M=2.0 and the effects of ...

Spatio-Temporal Configurations of Dynamics Points in a 1D Space

This paper describes a spatio-temporal configurations building approach, which has been applied to dynamics points in 1-dimensional space. In this approach, a temporal logic, Allen’s time intervals, is crossed with a new spatial logic based on topology called spatial states. These spatial states are derived from topological relationships and a new concept of degenerate topological relationships...

Impact of motion limits on sloped wave energy converter optimization

In a previous article [1] (subsequently referred to as the ‘original study’ and whose prior reading is recommended to make the most of what follows), the authors explored the concept of sloped power take-off (PTO) for a free-floating wave energy converter (WEC) using linear potential flow theory. Part of the study focused on the optimization of four parameters: the mass reference m2, its vertic...

Linear approach to motion estimation using generalized camera models

A well-known theoretical result for motion estimation using generalized camera model is that 17 corresponding image rays can be used to solve linearly for the motion of a generalized camera. However, this paper shows that for many common configurations of the generalized camera models (e.g., multi-camera rig, catadioptric camera etc.), such a simple 17-point algorithm does not exist, due to som...
