9906084RandDescription: This award is for support of a cooperative project by Dr. Richard Rand, Department of Theoretical and Applied Mechanics at Cornell University and Dr. Mohamed Belhaq, Department of Physics, Laboratory of Mechanics, Faculty of Science, University Hassan II, Ain Chock, Casablanca, Morocco. The two scientists plan to investigate quasi-periodic oscillations, chaos and the control of chaos in certain physical systems. The two scientists' groups have independently developed new ideas on these topics that provide the basis for the proposed research. The research project concerns a theoretical, numerical and experimental study of parametric convective instability in traditional and magnetic fluids. Attention will be focused on the case of a fluid layer simultaneously forced by periodic variations in body forces and in temperature gradient. Investigations will be made of the quasi-periodic behavior, and a stability analysis of the basic state of the system will also be carried out. The results will be compared with experimental work.Scope: This award will allow collaboration between two qualified scientists who have done independent research. The work is to be divided between the two sides based on the special skills and the available resources. Dr. Belhaq has spent the summer of 1997, under a Fulbright grant, working with Dr. Rand at Cornell University, so it is expected that the two will collaborate with each other successfully. This proposal meets the INT objective of increasing US-foreign collaboration in areas of mutual benefit.

9906084兰德描述：该奖项是为了支持康奈尔大学理论与应用力学系的Richard兰德博士和摩洛哥卡萨布兰卡Ain Chock的哈桑二世大学理学院物理系力学实验室的Mohamed Belhaq博士的合作项目。 这两位科学家计划研究准周期振荡、混沌以及某些物理系统中的混沌控制。 这两个科学家小组已经独立开发了关于这些主题的新想法，为拟议的研究提供了基础。 该研究项目涉及传统流体和磁性流体中参数对流不稳定性的理论、数值和实验研究。 注意力将集中在流体层的情况下，同时迫使在体力和温度梯度的周期性变化。 研究了系统的准周期行为，并对系统的基本状态进行了稳定性分析。 研究结果将与实验工作进行比较。范围：该奖项将允许两名独立研究的合格科学家进行合作。 这项工作将根据双方的特殊技能和可用资源进行分工。 Belhaq博士在1997年夏天，在富布赖特基金的资助下，与兰德博士在康奈尔大学一起工作，因此预计两人将成功地合作。 该提案符合情报与情报部在互利领域加强美国与外国合作的目标。
