当代年轻人面临的道德困境及教育对策

本文着重分析了当代一部分年轻人道德迷失、存在迷失、行上迷失的道德困境的深层现状.从主、客观两方面多角度地剖析了这种道德困境形成的原因.将传统道德观念与当今道德规范溶为一体,从广阔的社会背景入手,阐述解决当代年轻人道德困境问题的教育对策.     

中国民航"禁折令"的"囚徒困境"

利用博弈论的方法，对中国民航业施行多年的“禁折令”进行分析，指出各航空公司在“禁折令”中的博弈属于完全信息静态博弈。通过对民航业差别产品价格竞争需求曲线模型的分析，证明了“禁折令”所形成的价格卡特尔具有非稳定性，各航空公司存在突破“禁折令”限制的违约冲动，因此，实施机票打折销售，是市场运作的客观要求和必然趋势。     

当前农村职业教育的发展困境及对策研究

农村职业教育是实现农业产业化、农村现代化、农村城镇化的重要途径。农业要发展,农民要致富,农村要改变现状,农村职业教育就必须摆脱现实困境。根据农村职业教育发展中存在的办学定位不准等问题进行探讨,并对造成这些问题的原因进行分析,提出相关对策建议。     

Unlicensed Spectrum Sharing Game Between LEO Satellites and Terrestrial Cognitive Radio Networks

By cognitive radio,the low Earth orbit(LEO) satellites may prefer to operate in the unlicensed spectrum which is open to all the users,and compete for the limited resources with terrestrial cognitive radio networks(CRNs).The competition can be regarded as a game and analyzed with game theory.This particular unlicensed spectrum sharing problem is modeled here,and the special properties of "spatially-distinguished-interference" and the short period of the interactions between satellites and terrestrial CRNs are explored.Then,the problem is formulated as a "partially-blind" finitely repeated prisoner’s dilemma by game theory.Finally,we begin with two promising spectrum sharing schemes,which can be used to enforce the frequency reuse among the remotely located terrestrial CRN players as well as to overcome the observation noise.By analysis and comparison,it is proposed that the novel refreshing-contrite-tit-for-tat(R-CTFT) is the optimal spectrum sharing scheme.Simulation results verify that it can be used to utilize the spectrum most efficiently.     

Continual learning fault diagnosis:A dual-branch adaptive aggregation residual network for fault diagnosis with machine increments

As a data-driven approach, Deep Learning(DL)-based fault diagnosis methods need to collect the relatively comprehensive data on machine fault types to achieve satisfactory performance. A mechanical system may include multiple submachines in the real-world. During condition monitoring of a mechanical system, fault data are distributed in a continuous flow of constantly generated information and new faults will inevitably occur in unconsidered submachines, which are also called machine increments....
