Documentation framework for computer network design reviews
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540) - - Trang 11-14
D.S. Appleby, D. Callahan
A documentation framework is proposed to assist quality assurance teams in the analysis of complex computer network designs. The framework includes three elements: (1) a requirements definition, (2) a design depiction, and (3) the identification of potentially problematical interfaces. Requirements definition begins with nominal statements describing general design requirements; these statements u...... hiện toàn bộ

Watermark recovery with a DCT based scheme employing nonuniform imbedding
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540) - - Trang 157-161
I. Retsas, R. Pieper, R. Cristi
Digital Watermarking is a highly evolving field, which involves the embedding of a digital signature under a multimedia object (image, video, audio) for the purpose of copyright protection In our paper we propose a method of embedding watermarks in still digital images in the DCT domain. A unique approach of rating the 8/spl times/8 blocks of the image DCT coefficients is proposed. The experimenta...... hiện toàn bộ

Nội suy và ước lượng đạo hàm của hình ảnh sử dụng biến đổi cosine rời rạc Dịch bởi AI
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540) - - Trang 167-170
G.J. Foster, N.M. Namazi
Một tín hiệu có thể được biểu diễn hoàn toàn bằng tổng có trọng số của bất kỳ tập hợp hàm cơ sở hoàn chỉnh và trực giao. Biến đổi cosine rời rạc (DCT) từ lâu đã được sử dụng trong xử lý hình ảnh bởi vì, trừ khi so với biến đổi Karhunen-Loeve, nó thường cung cấp mức độ nén hình ảnh cao nhất trong các biến đổi hình ảnh thường được sử dụng. Ngoài việc sử dụng trong nén, DCT cũng có thể được sử dụng n...... hiện toàn bộ

Web-based experimentation integration in engineering curricula: experience in deploying resources distributed among universities
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540) - - Trang 66-70
D. Gillet, O.D. Crisalle, H.A. Latchman
Web-based experimentation is a paradigm currently deployed by various clusters of traditional and open universities for the main purpose of enhancing the offering of didactic resources designed to strengthen hands-on practice in engineering education by sharing laboratory experiments distributed worldwide. Web-based experimentation also offers an tremendous opportunity to add flexibility in tradit...... hiện toàn bộ

Reusable launch vehicle attitude control using a time-varying sliding mode control technique
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540) - - Trang 81-85
Y.B. Shtessel, J.J. Zhu, D. Daniels
We present a time-varying sliding mode control (TVSMC) technique for reusable launch vehicle (RLV) attitude control in ascent and entry flight phases. In ascent flight the guidance commands Euler roll, pitch and yaw angles, and in entry flight it commands the aerodynamic angles of bank, attack and sideslip. The controller employs a body rate inner loop and the attitude outer loop, which are separa...... hiện toàn bộ

Methodology for the development of an electronic medical record
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540) - - Trang 406-411
J. Dahle, D.W. Callahan
Electronic medical records (EMRs) and computer based patient records (CPRs) hold the opportunity to improve patient care, reduce costs, and facilitate research in medicine. Far too often, however, healthcare organizations and practitioners find that these systems are too costly, lack essential features, or work improperly for their setting. As the result, many decide to develop their own EMR or CP...... hiện toàn bộ

Steering controller design using scale-model vehicles
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540) - - Trang 476-478
S.R. Burns, R.T. O'Brien, J.A. Piepmeier
A scale-model, experimental apparatus is developed to design and evaluate steering controller designs. The controller is designed using linear quadratic optimal control methods on a standard four-state vehicle model. The apparatus simulates the human driver using a scale-model vehicle, a treadmill, and a vision system.

Supervised control of cooperative multi-agent robotic vehicles
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540) - - Trang 386-390
A. Shirkhodaie
In this paper, we address some of technical challenges associated with supervised tactical mobility behaviors modeling and control of a group of cooperative multi-agent robotic vehicles. Cooperative task planning of robotic systems is a dynamic and complex problem and very challenging. The challenge comes from many avenues including task decomposition, assignment, resource allocation, and task exe...... hiện toàn bộ

Decentralized load frequency control in a deregulated environment using disturbance accommodation control theory
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540) - - Trang 302-306
K. Sedghisigarchi, A. Feliachi, A. Davari
In this paper, a decentralized controller is proposed for the load frequency control problem in a deregulated environment. The deregulation scenario considered here assumes that generating units in each area supply regulated power according to their energy contracts. Disturbance accommodating controllers (DAC) are designed which are decentralized controllers using frequency and tie-line power meas...... hiện toàn bộ
