Predicting phase equilibria in polydisperse systems

Many materials containing colloids or polymers are polydisperse: they comprise particles with properties (such as particle diameter, charge, or polymer chain length) that depend continuously on one or several parameters. This review focuses on the theoretical prediction of phase equilibria in polydisperse systems; the presence of an effectively infinite number of distinguishable particle specie...

stability and attraction domains of traffic equilibria in day-to-day dynamical system formulation

در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...

Modeling, Control and Inversion of Multi-Phase Equilibrium Reactor Systems

We propose a simplified modeling approach for multi-phase reactor systems. The model can be used to determine system characteristics, explore parameter sensitivity and test control strategies. The model is based on the thermodynamic equilibrium assumption and invariant inventories to make it computationally inexpensive. We show that the control approach based on the overall inventories of the s...

Dynamics and Control System Design for Biodiesel Transesterification Reactor

The immiscibility of vegetable oil in methanol provides a mass transfer challenge in the early stages of Transesterification reaction in the production of biodiesel. It is of a great significance to design high-performance nonlinear controllers for efficient control of these nonlinear processes to achieve closed-loop system’s stability and high performance of a biodiesel CSTR. A mathematical mo...
