Life and Motion Configurations: A Basis for Spatio-temporal Generalized Reasoning Model
نویسندگان
چکیده
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-temporal states decision tree is presented. Based on this new representation, we construct a finite set of life and motion configurations which can be seen as a way to categorise spatio-temporal histories. Then, we present the model itself which is based on 25 generalized life and motion configurations. Indeed, these generalized configurations are assimilated to line-line topological relationships obtained by projecting life and motion configurations in a primitive space. Finally, generalized life and motions configurations conceptual neighbourhood diagram and their interpretation in natural language are given.

Generalized life and motion configurations reasoning model
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...
متن کاملSpatio-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...
متن کاملContext-aware Modeling for Spatio-temporal Data Transmitted from a Wireless Body Sensor Network
Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...
متن کاملSpatio-Temporal Parameters' Changes in Gait of Male Elderly Subjects
Objectives: The purpose of this study was to compare spatio-temporal gait parameters between elderly and young male subjects. Methods & Materials: 57 able-bodied elderly (72±5.5 years) and 57 healthy young (25±8.5 years) subjects participated in this study. A four segment model consist of trunk, hip, shank, and foot with 10 reflective markers were used to define lower limbs. Kinematic data c...
متن کاملTopological Spatio-Temporal Reasoning and Representation
We present here a theory of motion from a topological point of view, in a symbolic perspective. Taking space-time histories of objects as primitive entities, we introduce temporal and topological relations on the thus defined space-time to characterize classes of spatial changes. The theory thus accounts for qualitative spatial information, dealing with underspecified, symbolic information when...
