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...

Day-to-day variability of adequacy indexes in peritoneal dialysis.

BACKGROUND The achievement of dialysis adequacy targets in peritoneal dialysis (PD) is assessed by the calculation of the Kt/V and creatinine clearance (C(Cr)) obtained by collecting dialysate and urine, usually two or three times a year. Prescription decisions are based on such adequacy assessments, regardless of any variability in the single measurements. The aim of our study was to assess th...

The effects of day-to-day variability of physiological data on operator functional state classification

The application of pattern classification techniques to physiological data has undergone rapid expansion. Tasks as varied as the diagnosis of disease from magnetic resonance images, brain-computer interfaces for the disabled, and the decoding of brain functioning based on electrical activity have been accomplished quite successfully with pattern classification. These classifiers have been furth...

A Least Squares Method for Origin-destination Estimation Incorporating Variability of Day-to-day Travel Demand

The estimation of an origin-destination (O-D) trip matrix from observed link flow is an essential part of the 4-step transport planning process. Conventional methods for estimating O-D trip matrices usually consider the fluctuation of link flows observed from loop counts as an error term that can be ignored, resulting in a significant loss of information. This work, instead, explicitly consider...
