A Linearized Statistical XPM Model for Accurate Q-factor Computation

Fast and Accurate Statistical Q-factor computation for impairment-aware RWA problems

Physical layer impairments (PLI) need to be considered in the Routing and Wavelength Assignment (RWA) process in all-optical networks to ensure the provisioning of good quality optical connections (i.e., lightpaths). The quality of the provisioned lightpaths can be quantified using the so-called Q-factor. Impairment-aware RWA (IA-RWA) algorithms include the Q-factor evaluation in their decision...

AN ACCURATE SOLUTION FOR THE TWODIMENSIONAL MODEL OF ALBITE USING STATISTICAL MECHANICS

A two-dimensional model of Al, Si ordering in alkali feldspar is formulated and used to calcul~tea ccurately the configurational entropy for the model. For this purpose, a new method called Independent Basic Unit or IBU is introduced. To compare the results with the exact values, this method is applied to the onedimensional model of albite. The results given by IBU are found to be accurate ...

A Comparison of Different Control Design Methods for the Linearized CSTR Temperature Model

Continuous Stirred Tank Reactor (CSTR) has particular importance in chemical industry. CSTR has usually a nonlinear behavior which makes it difficult to control. The reactor has two parameters: the concentration and temperature of mixture both of which are uncertain. This case of CSTR has large disturbance in domain. In order for disturbance rejection, a controller has to be designed. In this p...

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
