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...
Effect of antiresorptive therapy on day-to-day variation of urinary free deoxypyridinoline excretion.
decrease the risk of complications. Accordingly, the revised cutoff for FPG was established on the basis of the risk for the development of complications of diabetes. Analysis of several studies revealed that the approximate thresholds for increased risk of retinopathy and microvascular and macrovascular disease were 6.9 mmol/L (125 mg/dL) and 11.1 mmol/L (200 mg/dL) for fasting and 2-h postloa...
متن کاملDay-to-day variation of urinary NGAL and rational for creatinine correction.
OBJECTIVES The number of clinical studies evaluating the new tubular biomarker urinary neutrophil gelatinase-associated lipocalin (U-NGAL) in urine are increasing. There is no consensus whether absolute U-NGAL concentrations or urinary NGAL/creatinine (U-NGAL/Cr) ratios should be used when chronic tubular dysfunction is studied. The aim was to study the biological variation of U-NGAL in healthy...
متن کاملDay - to - Day Variation of the Normal Orthogonal Electrocardiogram
Day-to-day variation of the corrected orthogonial electrocardiogram was investigated in 20 normal subjects. Ten recordings were made in each individual witlh chest electrode positions left unmarked first, after which 10 subjects underwent another series of 10 consecutive daily recordings with marked electrode locations. Mean and maximal day-to-day variations of durations and amplitudes of diffe...
متن کاملCorrect and incorrect estimation of within-day and between-day variation.
Between-day variance is an ambiguous term representing either total variance or pure between-day variance. In either case, it is often incorrectly calculated even though analysis of variance (ANOVA) and other excellent methods of estimation are available. We used statistical theory to predict the magnitude of error expected from using several intuitive approaches to estimation of variance compo...
