高等数学分层次教学的探索与实践

随着招生规模的不断扩大,各高校学生的整体素质有所下降,并且个体差异很大,这给高等数学教学带了前所未有的难度,为了改变这一现状,一些院校开展了分层次教学改革的尝试,笔者根据多年来分层次教学改革的经验,深入探讨了高等数学分层次教学的必要性、意义、具体实施方案等,提出了建设性的对策和建议,并对自己的教学实践进行了详细的总结和分析。

数学建模课程教学改革的新思路

Influence of Parallel Computational Uncertainty on Simulations of the Coupled General Climate Model

Parallel computational uncertainty, arising from the non-associativity of floating-point arithmetic in parallel reductions, can introduce perturbations in climate model …

An Improvement of the Too Cold Tongue in the Tropical Pacific with the Development of an Ocean-Wave-Atmosphere Coupled Numerical Model

The \"cold tongue\" bias in the tropical Pacific is a common error in coupled general circulation models (CGCMs). We developed an ocean-wave-atmosphere coupled model by introducing …

Bred-Ensemble Ocean Forecast of Loop Current and Rings

This study examines the use of the breeding method to generate ensembles for ocean forecasting, specifically focusing on the Loop Current and associated rings during Hurricane …

时间测度上具变号系数时滞微分方程解的渐近性与振动性

考虑时间测度上一类时滞微分方程的振动性,建立了这类方程的解振动的充分条件,同时,讨论了该方程非振动解的渐近性质。

风险管理测度VaR和TCE的实证研究

针对单一金融产品和由多种资产组成的投资组合两种情况,用几只股票的历史收盘数据实证比较了两种先进的度量金融市场风险测度———风险值(VaR)和尾部条件期望(TCE)的有效性。结果显示,TCE比VaR更有效。
