9907439 Poulton描述：该奖项旨在支持由亚利桑那州图森市亚利桑那大学采矿和地质工程系Mary M.Poulton博士和埃及开罗国家研究中心地质和地球物理科学系Safwat A.Hussain博士领导的两个团队的合作项目。其他与会者包括亚利桑那州图森市Zonge工程和研究组织主席Ken Zonge博士和开罗大学博士生Hesham El-Kaliouby先生。这些团队计划为瞬变电磁数据寻求一种准确的解释方法，这种方法可以很容易地应用于地下水和矿产勘探。导电岩石和矿物具有电性，其特征是在低频范围内具有弥散的复电阻率，称为激发极化(IP)。这些激电效应可以用透射电子显微镜方法检测到。研究人员计划开发一种方法来利用激电效应，并获得关于含水层和矿物的电学性质的有价值的信息。将有必要分析由于具有不同参数的目标的存在而获得电压响应的正向问题，所述参数例如是电属性、形状、深度和位置，然后通过使用神经网络来寻找逆解以找到目标的属性。范围：美国团队非常有资格参与这个项目。Poulton博士在开发神经网络和使用神经网络解释环境应用中的电磁地球物理数据方面特别有经验。Ken Zonge博士在这一领域拥有有用的实践经验，他的组织Zonge Engineering拥有必要的资源。埃及和美国科学家之间的合作对实现该项目的目标特别有用。拟议的活动将有助于定位地下水资源，这是埃及和其他中东国家面临的一个重要问题。该项目将通过与美国专家的互动，帮助埃及的科学人力资源。获得的数据将有助于美国科学家发展基础科学和应用科学。这一建议符合INT支持在共同感兴趣的领域进行合作研究的目标。该项目得到了美国-埃及联合基金计划的支持，该计划向两国的科学家和工程师提供赠款，以开展这些合作活动

9907439PoultonDescription: This award is to support a collaborative project by two teams lead by Dr. Mary M. Poulton, Department of Mining and Geological Engineering, University of Arizona, Tucson, Arizona and Dr. Safwat A. Hussain, Department of Geological and Geophysical Sciences, The National Research Center, Cairo, Egypt. Others participants are Dr. Ken Zonge, President of Zonge Engineering and Research Organization, Tucson, Arizona and Mr. Hesham El-Kaliouby, who is a Ph.D. candidate at Cairo University. These teams plan to seek an accurate interpretation method for transient electromagnetic (TEM) data that can readily be applied to ground water and mineral exploration. Conducting rocks and minerals exhibit electrical properties, which are characterized by a dispersive complex resistivity in the low frequency range, called induced polarization (IP). These IP effects may be detected using TEM methods. The researchers plan to develop a method to exploit the IP effect and gain valuable information about the electrical properties of aquifers and minerals. It will be necessary to analyze the forward problem of finding a voltage response due to the presence of a target having different parameters such as electrical properties, shape, depth, and location, and then to find inverse solution through the use of a neural network to find the properties of the target. Scope: The US team is well qualified for this project. Dr. Poulton is especially experienced in the development of neural networks and use of neural network interpretation of electromagnetic geophysical data for environmental applications. Dr. Ken Zonge has useful practical experience in this area, and his organization, Zonge Engineering, has the necessary resources. The collaboration between Egyptian and US scientists is particularly useful to achieve the objectives of the project. The proposed activity would help locate ground water resources, an important issue for Egypt and other Middle East countries. The project will help the Egyptian scientific human resources through the interaction with US experts. The data obtained will help US scientists with developing basic and applied sciences. This proposal meets the INT objective of supporting collaborative research in areas of mutual interest. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities
