Performance evaluation of a complete Lagrangian KTGF approach for dilute granular flow modelling

Dilute Granular Flow as a Micropolar Fluid

We show that a micropolar fluid model successfully describes granular flows on a slope. Micropolar fluid is the fluid with internal structures, and the coupling between the rotation of each particle and the macroscopic velocity field is taken into account; it is a hydrodynamical framework suitable for granular systems which consists of particles with macroscopic size. It is demonstrated that th...

A new approach for performance evaluation of energy-related enterprises

Oil is among the most effective and the largest industries in the world. Given that it supplies a large percentage of the world’s energy and plays a significant role in the national power and international credit of countries, it has a huge impact on our world today. Iran has  huge oil reserves, and plays a key role in the exchange of the required energy in the world. In order to improve the pe...

A NEW APPROACH FOR EVALUATION OF SEISMIC SLOPE PERFORMANCE

The evaluation of seismic slope performance during earthquakes is important, because the failure of slope (such as an earth dam, natural slope, or constructed earth embankment) can result in significant financial losses and human. It is important, therefore, to be able to forecast such displacements induced by earthquake. However, the traditional forecasting methods, such as empirical formulae,...

A perturbative approach to Lagrangian flow networks

An SDL Modelling Approach for Performance Evaluation of ATM Networks

In this paper we describe a methodology to model and simulate networks based on the asynchronous transfer mode (ATM), and show an example of its use. These networks are designed to integrate multiple communication services, providing di erent service classes with di erent characteristics. To support their provision, a large variety of adaptation protocols and tra c management mechanisms are req...
