1. Introductory material

1.1 Introduction to Florida International University

Florida International University (FIU) is an urban, multi-campus, institution located in Miami, Florida, with campuses at University Park (Main Campus) and North Miami (Biscayne Bay Campus), and more recently a new campus, one mile away from University Park, the Engineering and Applied Sciences Campus. Chartered by the Florida Legislature in 1965, the University opened its doors in 1972 to the largest entering class in United States collegiate history. FIU is a member of the State University System of Florida. FIU currently serves 32,196 students with 1,100 full-time faculty, and has 90,000 alumni. FIU is the largest university in South Florida, and awards more baccalaureates for minority students than any other institution in the continental United States.  The percentage of African American enrolled at FIU (nearly 15%) places us second only to FAMU in the State of Florida. FIU now offers 135 major programs at the Bachelor’s degree level, 125 major programs at the Master’s degree level and 48 major programs at the Doctoral degree level. FIU is over the next decade projected to become a national leader in the conferral of master’s and doctoral degrees to minority candidates.

1.1.1 Increasing Enrollment Trends at FIU: FIU continues to experience an increase in enrollments over the past few years: Fall 1992: 22,387; Fall 1993: 23,842; Fall 1994: 26,501; Fall 1995: 28,096; Fall 1996: 29,639; Fall 1997: 30,092; Fall 1998: 30,583; Fall 1999: 31,274; Fall 2000: 32,196.

1.1.2 Minorities and Women Enrollment Statistics: Today, nearly 68% of FIU's 32,196 students are minority, of whom nearly 53% are Hispanic and 15% are African-American.  Female students constitute about 57% of the total student population.

1.2 Introduction to the project

The NSF-MII support has allowed us to enhance greatly an academic infrastructure; we call the Center for Advanced Technology and Education (CATE). The center constitutes a multidisciplinary research environment engaging researchers as well as facilitating classroom and laboratory-based instruction in key technology areas.  The integrated infrastructure is viable for cutting-edge educational activities in support of both undergraduate and graduate students, many of whom are women and minority.

With the establishment of the Center for Advanced Technology and Education (NSF-CATE) since 1993 from early NSF-IIMI support, we have expanded our research and educational activities to include:

-          Image Processing and Computer Vision - EEG-Based Brain Research –Human (Brain) Computer Interfaces - Robotics for Motion Planning and Automated Guidance - Biosignal Processing and Biomedical Applications in Confocal Microscopy and Flow Cytometry - Parallel and Distributed Processing - Web Design and Development - Computer Networking.

The continued NSF-MII support have led to the following important accomplishments:

1. Establishment of an enhanced infrastructure viable for cutting-edge research and education

2. Exploration of research avenues that are broad in scope but focused in their objectives

3. Development and enhancement of curriculum to meet industry demand and reflect technological change

4. Investment on human capital involving faculty and students from different disciplines working on shared research/educational goals

5. Laying down the research foundation for strong industry and medical partnerships.

Furthermore, this year, we have supported 1 postdoctoral fellow, 6 Ph.D. students, 12 MS students, and 23 undergraduates.  Section 4.1 provides a more detailed account on these students.  It is noted that graduate students are assigned 20hrs per week contractually.  Undergraduates as OPS are on time cards performing 10 to 20 hrs a week depending on their course load and other academic activities. Participating faculty perform 25 to 40% of their time on CATE center related activities.

2.3 Indications of success (Outputs)

2.3.1 Number of students supported (directly through financial support or indirectly):

Direct support has been provided to a total of 21 Graduate students (7 Ph.D. and 14 MS), and to 23 undergraduates.  We also support about 60 to 80 students per term indirectly in the Web design and Interactive Design laboratories for interactive teaching and project development.

2.3.2 Supported students receiving degrees (by BS, MS, or PHD):

B.S. degree (10): Luz Camacho, Claudia Rodríguez, Kirenia Nunez, Tarla Toomer, Mercedes Cabrerizo, Alexis Bussiere, Robert Hazbun, Orfirio Sánchez, Michel Martinez, and Alejandro Simon. 

M.S. degree (7): Erika Suarez; Daniela Viegas; Danmary Sánchez; Alison Valdivieso; Oscar Silvera; Ovidio Sanchez, and Euton Lyons.

PH.D. degree (2): Patricio Vidal, and John Riley, expected to defend in the fall of 2001.

2.3.3 Specific projects or programs using the infrastructure:

Researchers in the CATE center attempt to bring their research findings into the realm of practicality. New algorithms and techniques are being developed for such things as diagnostics in medical applications, and human-computer or brain-computer interfaces that will better the lives of those among us who live with disabilities, focusing on visual impairment and motor disability.  Applications of neuroscience are also performed in the context of brain functional mapping and the neuro-analysis of key brain disorders such as epilepsy.  We publish on the average 15 to 20 publications per year mainly in the areas of signal/image processing, biomedical applications, human-computer interfaces, and rehabilitation.

Some of the relevant projects we have worked on this past year include:

- Use of multidimensional flow cytometric data for blood cells classification, and allowing the discrimination of healthy blood cell subpopulations from unhealthy ones.

- We have worked on three different HCI prototypes to help people with disabilities:

(1)    A prototype based on portable eye-gaze tracking (EGT),

(2)    A prototype based on integrated EMG (electromyogram)/EGT;

(3)    A prototype based on 3-D sound as a computer interface to help people with visual disabilities. 

With enhanced understanding of EEG-based brain research, we intend to bring added insight to the theoretical foundation and the practical implications of the following research ideas:

1.Non-invasive EEG analysis using the ESI-256 for the Detection of interictal spikes in epileptic seizures.

2. Development of a new approach to understanding EEG activities using visual stimuli with the ESI-256

3. Design of an Electronic Neural Pulse (ENP) system for optimized and safe brain stimulation.

3. Evaluation

3.1 Degree of success

The infrastructure has been augmented with the establishment of new labs for interactive teaching, project development and research (refer to section 2.1).  All of our stated objectives have been met successfully, especially in student recruitment and in innovative research.   We have taken new research directions in neuroscience and HCI applications, which are expanding our potential for more critical research and theoretical findings.  Such noted success is a precursor for more peer-reviewed publications, as we increase our prospects for more funding from other sources such as NIH and the Whitaker foundation.

3.2 Outcome

This project has created new research opportunities, new teaching laboratories, and new curriculum, all in areas of critical technology need. Our graduating students are taking leadership roles in industry.  Our institution has recognized our contributions and has been very generous in meeting our space requirements and promised matching funds.  We have been featured on TV, and on several FIU brochures and catalogs.  We are at the center of every visit by dignitaries, colleagues, and students from other institutions and local colleges, all for the increased visibility we have given to our institution.

3.3 Impact

With the integration strategy we are pursuing (education-research-training), we seek to link the world of theoretical development to the realm of practicality and system design with significant potential for discovery and societal impact.  The notion of assistive system as means to improve the functional capabilities of individuals with disabilities will constitute one major impact. The other objective that of eliciting the functional mapping of the brain and the causality of key brain disorders will constitute another major impact.

5.2 Outcome Goals

5.2.1 Outcome Goal 1: Discoveries at and Across the Frontier of Science and Engineering

This past year, we have moved the ESI-256 Machine to the neuroscience center at Miami Children’s Hospital and have established a modern FIU-MCH Brain Functions Laboratory (BFL). The vision in establishing this multidisciplinary research and educational lab is to have it serve as a catalyst for our graduates to train and develop their creative thinking in the fields of neuroscience and human/brain-computer interfaces.  In the merging of these technologies, we see a fertile ground for the development of new methodologies and scientific discovery that (1) will meet the impending needs in neuroscience as we elicit both the functional mapping of the brain, and the causality of key brain disorders; and (2) perform HCI research that responds to the call of the National Science Foundation on the issue of Universal Accessibility and takes as its mission the Assistive Technology Act of 1998 (Public Law 100-407).

5.2.2 Outcome Goal 2: Connections between Discoveries and Their Use in Society:

The development of Human-Computer Interfaces as assistive real-time systems will come to improve the life of people with motor disabilities and visual impairment. We are currently working on prototype designs that will merge the benefits of Eye-Gaze Tracking (EGT), Electromyograms (EMG), Electroencephalography (EEG) and three-dimensional sound technologies.  Such designs will be supported by critical scientific procedures, experimental evaluations, and feasibility studies.

5.2.3 Outcome Goal 3: Diverse, Globally Oriented Science and Engineering Workforce:

The CATE center supports students, graduates and undergraduates alike, where more than 75% are minority, and where 53% are women.  The disciplines include computer engineering, electrical engineering and computer science.

5.2.4        Outcome Goal 4: Improved Achievement in Mathematics and Science Skills:

All of our students are capable of taking their theoretical know- how with strong background in Mathematics and apply it into applications and system design in relevant fields of science such as biomedical and medical.
