In design and analysis, standard references assume the pedestrian flow as unidirectional. In reality however, pedestrian flow is usually bi-directional. The main question pursued in this paper is that whether the main characteristics of pedestrian flow the same under uni- and bi-directional conditions. In order to achieve this goal, effect of bi-directional stream is inv...

This paper proposed a parallel automated assembly line system to produce multiple products having multiple autonomous guided vehicles (AGVs). Several assembly lines are configured to produce multiple products in which the technologies of machines are shared among the assembly lines when required. The transportation between the stations in an assembly line (intra assembly line) and among station...

The adaptive step trapezoid rule (TR) is a generally effective numerical integrator, but it is prone to ringing instability and solution stall. We introduce a new stabilization algorithm based on finite difference interrupts (FDI) that reduces ringing and prevents stall. Unlike previously reported stabilization schemes, our algorithm achieves stability and second order accuracy without incurrin...

Objective: Bryonia aspera (Stev. ex Ledeb) is a plant that grows in northeast of Iran. In the present study, cytotoxic and apoptogenic properties of B. aspera root extract was determined against HN-5(head and neck squamous cell carcinoma) and Hela (cervix adenocarcinoma) cell lines. Materials and Methods: HN-5 and Hela cell lines were cultured in DMEM medium and incubated with different concent...

Sophora pachycarpa Schrenk ex C.A.Mey. belongs to the family Fabaceae. Some species of the genus Sophora have shown to possess anti-proliferative and apoptosis-inducing activites in cancer cells. However, there is no available information addressing this effect in S. pachycarpa. Here, we investigated the cytotoxic effects of methanol extract and different fractions obtained from S. pachycarpa r...
