A framework for multi-user distributed virtual environments (DVEs) has been proposed. The proposed framework, incorporating two models (the functional model and the interconnection model), attempts to represent the common functionality, communication issues and requirements found in multi-user DVEs. The functional model concentrates on the DVE's functionality, while the interconnection model co...

Today the most organizations (e.g. banks and insurance institutes) consist of the various units which under the control of the main organization (unified management) act independently. Sometimes the manager presents some services which incur costs such as advertisement and introducing a new technology. Most organizations consist of several individual units. Resource allocation issue appe...

We derive some estimators of the scale parameter Rayleigh distribution under unified hybrid censoring scheme. also reliability function and entropy distribution. First, we obtain maximum likelihood estimator parameter. Second, Bayes using mean posterior Lastly, mode interval estimation (confidence interval, credible HPD interval) for compare proposed in sense squared error through Monte Carlo s...

Abstract We study four systems and their interactions. First, we formulate a unified system of coupled forward-backward stochastic partial differential equations (FB-SPDEs) with Lévy jumps, whose drift, diffusion, and jump coefficients may involve partial differential operators. An solution to the FB-SPDEs is defined by a 4-tuple general dimensional random vector-field process evolving in time ...

This article proposes a new approach for centralized path planning of multiple aircraft in presence of the obstacle-laden environment under low flying rules. The problem considers as a unified nonlinear constraint optimization problem. The minimum time and control investigate as the cost functions and the maximum velocity and power consider as the constraints. The pseudospectral method applies ...
