7Analysis of a population model with advection and an autocatalytic-type growth显示文摘This paper analyzes a population model with time-dependent advection and an autocatalytic-type growth.As opposed to a logistic growth where the rate of growth of the population decreases from the onset,an autocatalytic growth has a point of inflection where the rate of growth switches from an increasing trend to a decreasing trend.Employing the idea of Painleve property,we show that a variety of exact traveling wave solutions can be obtained for this model depending on the choice of the advection term.In particular,due to situations in resource distribution or environmental variations,if the advection is represented as a decaying function in time or an oscillating function in time,we are able to find exact solutions with interesting behavior.We also carry out a computational study of the model using an exponentially upwinded numerical scheme and illustrate the movement of the solutions and their characteristics pictorially.Valipuram Manoranjan Lewa'Alzaleq 2023International Journal of Biomathematics2023,16,2:0
8基于高维调制的模分复用系统性能研究显示文摘为了提高系统的传输容量和传输性能,提出了基于高维调制的模分复用通信技术。通过搭建的基于高维调制的模分复用系统,仿真分析了4b-4D和8b-8D高维信号在不同光信噪比、传输距离和模式耦合系数条件下的传输性能,并与传统的谱效率相同的二维调制信号QPSK进行了对比。实验结果表明,在目标误码率下,4b-4D信号和8b-8D信号所需信噪比分别比QPSK信号降低了2和4dB,传输距离分别比QPSK信号增加了20和40km。可见,随着信号维度的增大,信号的抗噪声性能及抗色散性能越好。此外,实验结果表明模式耦合对误码率的影响也随着信号维度的增加而减小。Enock Lewa Kashero 侯丹 宋正勋 胡贵军 2017半导体光电2017,38,2:0
