Global warming will certainly affect the abundance and distribution of disease vectors. The effect of global warming, however, depends on the complex interaction between the human host population and the causative infectious agent. In this work we review some mathematical models that were proposed to study the impact of the increase in ambient temperature on the spread and gravity of some insect-transmitted diseases. 相似文献

区间二次规划在确定模糊评价因素权向量中的应用 总被引:1,自引:0,他引:1
利用区间二次规划方法确定模糊综合评判中评价因素的模糊权向量,它的原理是:以区间的概念为基础。利用区问相离度公式计算使主观偏好值与客观偏好值的总差距最小的权向量就是所求的评价因素的模糊权向量。 相似文献

Multistep schemes for computing weak solutions of Lipschitzian quantum stochastic differential equations (QSDE) driven by certain operator-valued stochastic processes associated with the basic field operators of quantum field theory are introduced and studied. This is accomplished within the framework of the Hudson–Parthasarathy formulation of quantum stochastic calculus and subject to matrix element of solution being sufficiently differentiable. Results concerning convergence of explicit schemes of class A in the topology of the locally convex space of solution are presented.Numerical examples are given. 相似文献
