During the last four years, Tennessee State University has established an interdisciplinary NSF CREST center, the Center for Systems Science Research (CSSR), which consists of components from mathematics, physics/astronomy, and electrical/mechanical engineering. Research niches have been firmly established in each of these areas and, at present, the existing research base has matured enough to permit continued significant contributions to the body of scientific knowledge. These science/engineering niches form the four research thrust components of this renewal proposal: (1) optimal and robust control (electrical engineering), (2) modeling of complex astrophysical systems (physics/astronomy), (3) large-scale stochastic dynamic systems (mathematics), and (4) modeling of complex flows (mechanical engineering).These four research components from diverse science/engineering disciplines seek to understand the behavior of complex physical systems by utilizing mathematical models. CSSR researchers in each thrust component have worked independently and side by side for the last four years, and fruitful collaborative interactions have resulted in cross discipline approaches to problem solving.The Center for Systems Science Research has as its primary goals (1) the establishment of a permanent research base at Tennessee State University which produces new knowledge and quality, publishable, peer-reviewed research relevant to NSF research goals and (2) the enhancement of participation and substantial involvement of minority students and faculty in SMET research areas.In reference to Goal 1, the TSU CREST Center has published 171 articles, 139 of these in refereed journals or conference proceedings, during its first four years. Each thrust area has produced significant new knowledge, e.g. the control systems group introduced the concept of controller "fragility" which resulted in a special session at the 1999 American Control Conference, the astrophysics group confirmed the existence of extra solar planets by discovering the first planet in the star system HD 20945,the applied math group has expanded the probabilistic analysis and computational methods for large-scale stochastic dynamic systems, and the CFD groups collaboration with the NSF ERC at Mississippi State University has resulted in a model which predicts the effects of icing on the aerodynamics and structural characteristics of aircraft.During the same time period, the pursuit of Goal 2 has resulted in the support and participation of 35 undergraduate and 7 graduate African-American students on average per year. During the past four years, support for both graduates and undergraduates has averaged over $200,000 per year for various combinations of tuition, fees, room and board, and stipends, and this same level of support is requested for the renewal period. The CREST Student Program Coordinator matches student participants with CREST researchers. Students present their work at the TSU University Wide Research Symposium and at the NSF/NASA/TSU Student Research Symposium. Students have also been co-authors with CREST researchers on journal/conference papers.Thus far eight underrepresented minority students have received their MS degrees, five of whom are now pursuing a Ph.D. In the Fall Semester, 2001 the university began enrollment of students in the newly established Ph.D. program in Computer Information Systems Engineering which is housed in the College of Engineering, Technology, and Computer Science. The NSF HRD CREST program was the catalyst that "fast-tracked" this initiative through the university, the Tennessee Board of Regents, and the Tennessee Higher Education Commission.

在过去的四年中，田纳西州立大学建立了一个跨学科的NSF CREST中心，系统科学研究中心（CSSR），其中包括数学，物理/天文学和电气/机械工程的组成部分。在这些领域中的每一个领域都已牢固确立了研究领域，目前，现有的研究基础已经足够成熟，可以继续为科学知识作出重大贡献。这些科学/工程领域构成了这项更新建议的四个研究重点：（1）最优鲁棒控制（2）复杂天体物理系统的建模（物理学/天文学），（3）大规模随机动力系统（数学），（4）复杂流动的模拟来自不同科学/工程学科的这四个研究组成部分试图通过利用数学模型来理解复杂物理系统的行为。在过去的四年里，每个推力部件的CSSR研究人员都独立和肩并肩地工作，富有成效的合作互动导致了跨学科的问题解决方法。系统科学研究中心的主要目标是：（1）在田纳西州立大学建立一个永久的研究基地，产生新的知识和质量，可持续的，与NSF研究目标相关的同行评审研究，以及（2）加强少数民族学生和教师在SMET研究领域的参与和实质性参与。关于目标1，大津CREST中心发表了171篇文章，其中139篇发表在参考期刊或会议论文集上，在最初的四年里。每个推力领域都产生了重要的新知识，例如，控制系统小组引入了控制器“脆弱性”的概念，导致1999年美国控制会议的特别会议，天体物理小组通过发现星星系统HD 20945中的第一颗行星证实了太阳系外行星的存在，应用数学组扩展了大规模随机动态系统的概率分析和计算方法，计算流体动力学小组与密西西比州立大学的美国国家科学基金会ERC合作，已经形成了一个预测结冰对空气动力学和结构影响的模型在同一时期，为实现目标2，平均每年有35名本科生和7名研究生支持和参与。在过去四年中，对研究生和本科生的支助平均每年超过20万美元，包括各种学费、杂费、食宿费和津贴，延长期也需要同样水平的支助。CREST学生项目协调员将学生参与者与CREST研究人员相匹配。学生们在大津大学研究研讨会和NSF/NASA/大津学生研究研讨会上展示他们的工作。到目前为止，已有8名少数民族学生获得了硕士学位，其中5名正在攻读博士学位。在秋季学期，2001年大学开始招生的学生在新成立的博士学位。计算机信息系统工程专业，位于工程、技术和计算机科学学院。NSF HRD CREST计划是通过大学，田纳西州董事会和田纳西州高等教育委员会“快速跟踪”这一倡议的催化剂。
