Travel time is widely recognized as an important performance measure for assessing transportation system, it is a meaningful parameter in theory and practice. Previous researches about travel time mainly focus on two areas: first, the research object is the unit of the transportation network, and there is little research on the area transportation network travel time; second, previous researche...

Traditional solutions to shortest path problems on time-varying transportation networks only use traffic information at definite moment so as to ignore the fact that the travel time through a link is dependent on the time to enter it. In this paper, the travel speed instead of the travel time on each link of road networks was modelled as a time-interval dependent variable, and a FIFOsatisfied c...

An a priori route is a route which specifies an ordering of all possible customers that a particular driver may need to visit. The driver may then skip those customers on the route who do not receive a delivery. Despite the prevalence of a priori routing, construction of these routes still presents considerable challenges. Exact methods are limited to small problem sizes, and even heuristic met...

background: magnetic resonance imaging (mri) has improved the diagnosis and management of patients with multiple sclerosis (ms). montreal cognitive assessment (moca) is a brief, sensitive test that has been recommended by national institute of neurological diseases and stroke and canadian stroke network (ninds-csn) as a reliable tool to detect mild cognitive impairments. this study aimed to eva...

conclusions we conclude that volume of residual pneumoperitoneum is a contributing factor in the etiology of postoperative pain after laparoscopic cholecystectomy. results at the end of the study, 17 patients (30.9%) had no residual pneumoperitoneum after 24 hours; which 23 (41.81%) had mild residual pneumoperitoneum, eight (14.54%) had moderate pneumoperitoneum and seven (12.72%) had severe pn...
