Unsteady flow separation on the airfoils with local flexible membrane (LFM) has been investigated in transient and laminar flows by the finite volume element method. A unique feature of the present method compared with the common computational fluid dynamic softwares, especially ANSYS CFX, is the modification using the physical influence scheme in convection fluxes at cell surfaces. In contr...

The long term goal of this research is twofold: (1) develop an advanced multi-physics model with a multi-numerical solution techniques approach to predict nonlinear dynamic behavior of impact burial and flow-induced motion of flexible structures (mines) and surrounding sediments (sand) in the marine environment; and (2) calibrate resulting models with experimental and field measurements. The pr...

Feature modeling has become the most important method for representing variability and commonality in software product families. Several kinds of feature meta-models have been proposed. However, they can’t meet the requirements of dynamic Internet environment or software reuse. This paper proposes a feature meta-model which is based on ontology and FCM (Flexible Transaction Model). In particula...

In today’s distributed and dynamic business environment companies and their business processes are frequently subject to changes, requiring the ability to continuously evolve business processes in a flexible and dynamic way according to changing external conditions. Taking flexibility as the ability to react to changes by adaptation, it appears appropriate to take the environment, where a chang...

Océano is a prototype of a highly available, scaleable, and manageable infrastructure for an e-business computing utility. It enables multiple customers to be hosted on a collection of sequentially shared resources. The hosting environment is divided into secure domains, each supporting one customer. These domains are dynamic: the resources assigned to them may be augmented when load increases ...

The paper tackles the problem of managing the uncertainties during the execution of predictive schedules in a dynamic environment. The dynamic environment in question is represented by a simulation model – connected to a production scheduler system – with flexible modelling capabilities. The paper addresses the simulation module of the proposed architecture highlighting its main functionalities...

A robot moving in the presence of humans is highly constrained by the dynamic environment and the need to comply with human safety, preferences, cognition and actions. The dynamic nature of the environment should be taken into account at planning time and must be allowed for by flexible plan execution, to produce safe, efficient and legible robot behavior. Moreover, when the space in which huma...
