Tea crabapple (Malus hupehensis Redh. var. Pingyiensis) is a typical facultative apomictic apple rootstock. Its asexual seed formation is affected by environmental temperature; however, little is known regarding the mechanisms underlying this phenomenon. In this study, we found that unreduced embryo sacs escaped fertilization due to a developmental delay, which is referred to as the female-late-on-date...
Through the analysis of the behavior of mandatory lane changing and selectivity lane changing, this paper researches the effects of capacity of urban intersection, delays and the probability of rear-end collision resulting from the lane-changing behavior. The models of capacity, delay time and probability of rear-end collision are established respectively, and simulated delay is evaluated based on...
A dynamic traffic allocation algorithm based on packet delay and hops in Mobile Ad hoc networks is proposed. The algorithm is based on the minimization product of delay and the number of hops in each path and adjusts the traffic adaptively so as to make load-balanced which optimizes network resource utilization. Simulation demonstrated that the algorithm could dynamically balance the traffic allocation...
In order to improve the real-time performance of the switched Ethernet, genetic algorithm is used to optimize the subnet partition. Firstly, the existing methods are analyzed. Secondly, a linked list encoding and new operators for this special encoding are designed. Then, based on the network calculus, the calculating expression of the maximum network delay is proposed. Lastly, an experiment on ring...
A dynamic traffic distribution algorithm based on the minimization product of packet delay and packet energy consumption is proposed. The algorithm is based on packet delay and energy consumption in allocating traffic, which can optimize the network performance. Simulation demonstrated that the algorithm could dynamically adjust to the traffic distribution between paths, which can minimize the product...
