r Publis .030 : +1 413 mass.ed Summary Flood routing processes in the middle Yellow River basin are complex since they consist of three types of flood: bidirectional, convergent and divergent flood flows between the main channel and its tributaries. We propose three computation schemes to simulate the complex flood routing: a simple scheme for a single main channel with no tributary or backwate...

In the previous research on traffic flow prediction models, most of models mainly studied time series flow, and spatial correlation was not fully considered. To solve this problem, paper proposes a method to predict spatio-temporal characteristics short-term by combining k-nearest neighbor algorithm bidirectional long memory network model. By selecting real-time data observed high-speed roads i...

Energy storage system has been widely applied in power distribution sectors as well as in renewable energy sources to ensure uninterruptible power supply. This paper presents a model predictive algorithm to control a bidirectional AC-DC converter, which is used in an energy storage system for power transferring between the three-phase AC voltage supply and energy storage devices. This model pre...

Regional changes in retinal blood flow following inferior and subsequent superior argon laser half fundus photocoagulation treatment were measured in six diabetic patients with advanced retinopathy. Centreline blood velocity, vessel diameter, and blood flow in major inferior and superior temporal retinal arteries were measured at baseline and following each treatment using the bidirectional las...

The present paper aims to study the effect of skill complexity during different delays on bidirectional transfer on bidirectional transfer of tracking task in different stages (pretest, acquisition phase, immediate transfer, one-day delayed transfer, two-day delayed transfer, and seven-day delayed transfer). Three variables including handedness, time lagges, and skill complexity were studied. T...

One of the major distinctions of riparian habitats is their linearity. In linear habitats, gene flow is predicted to follow a one-dimensional stepping stone model, characterized by bidirectional gene flow between neighboring populations. Here, we studied the genetic structure of Myricaria germanica, a threatened riparian shrub which is capable of both wind and water dispersal. Our data led us t...

The calibration and validation of pedestrian simulations require the acquisition of empirical evidences of human behaviour. The current work presents the results of an experiment focused on the potentially combined effect of counter flow and grouping on pedestrian dynamics. In particular, we focused on: (i) four different configurations of flow ratio (the rate between the minor flow and the tot...
