the paper discusses the current state of research concerning railway network timetabling and traffic management. timetable effectiveness is governed by frequency, regularity, accurate running, recovery and layover times, as well as minimal headway, buffer times and waiting times. analytic (queuing) models and stochastic microsimulation are predominantly used for estimation of waiting times and ...

Although viral spreading processes taking place in networks are commonly analyzed using Markovian models in which both the transmission and the recovery times follow exponential distributions, empirical studies show that, in most real scenarios, the distribution of these times are far from exponential. To overcome this limitation, we first introduce a generalized spreading model that allows tra...

In this study, anesthetic effects of five different concentrations of 2-phenoxyethanol (0.2, 0.3, 0.4, 0.5 and 0.6 ml/L) and clove oil (0.50, 0.75, 1.00, 1.25 and 1.50 ml/L) on rainbow trout (Oncorhynchus mykiss) were studied at temperatures 7, 13 and 18ºC. For this purpose, 900 fish (39.08 ± 1.13 g and 15.48 ± 0.21 cm) were used in the experiment. Induction time of 2-phenoxyethanol and clove o...

0' ABSTRACT Ten volunteers were exposed to high intensity double pulse light flashes with flash fields subtending l-, 3?, 50, 10P, and 15q of visual angle. Flashblindness recovery times for several aircraft instruments were measured for each flash field diameter, Countermeasures including looking around the afterimage and body movement were permitted on some of the trials. Recovery time increas...
