This paper describes a method and automation approach for ontology life cycle management. First, the challenges associated with knowledge creation are summarized. The problems associated with ontology capture, analysis, and maintenance are used to motivate the need for ontology life cycle management. Then a semi-automated method for ontology life cycle management is described. The method is com...

This paper describes a new method for the temporal segmentation of periodic human activities from continuous real-world indoor video sequences acquired with a static camera. The proposed approach is based on the concept of inter-frame similarity matrix. Indeed, this matrix contains relevant information for the analysis of cyclic and symmetric human activities, where the motion performed during ...

One of the most fundamental results in analysing the stability properties of periodic orbits and limit cycles of dynamical systems is Poincaré’s theorem. The proof of this result involves system analytic arguments along with the Hartman–Grobman theorem. Using the notions of stability of sets, lower semicontinuous Lyapunov functions are constructed to provide a Lyapunov function proof of Poincar...

introduction: studying the hydrological cycle, especially in large scales such as water catchments, is difficult and complicated despite the fact that the numbers of hydrological components are limited. this complexity rises from complex interactions between hydrological components and environment. recognition, determination and modeling of all interactive processes are needed to address this i...
