computerized three-dimensional models based on the Visible Human Project do reflect rich anatomical details, but up to now, they do not allow for the representation of the knowledge of acupuncture, an important component of Traditional Chinese Medicine. In this paper, original work for 3D representation of acupoints and acupuncture treatment is reported. This is based on the dataset of the male Visible Human, the computerized 3D models provided by VOXEL-MAN as well as the anatomic knowledge based on our systematic research work. The model contains the spatial description resulting from segmentation, graphic modeling, volume visualization and localization of acupoints, and a linked knowledge base, which is a hierarchical structure providing detailed knowledge of Chinese medicine. A 3D anatomical atlas of acupuncture based on this model is almost finished and generally available.

computers in Cardiology (CinC)

作者： S. Jankowski A. Oreziak A. Skorupski H. Kowalski Z. Szymanski E. Piatkowska-Janko Institute of Electronic Systems Warsaw University of Technology Warsaw Poland Institute of Electronic Systems Warszawa Poland Chair and Department of Internal Medicine and Cardiology Central Teaching Hospital Warsaw Poland Institute of Computer Science Institute of Radioelectronics-Warsaw University of Technology Warsaw Poland

The paper presents a new approach to computer-aided analysis of ECG Holter recordings. In contrast to existing tools it is a learning system: the pertinent features of the signal shape are automatically discovered upon the examples carefully selected and commented by cardiologists. Mathematical basis of our system is the theory of support vector machines that are applied for two tasks: signal approximation and pattern classification. Numerical procedures implement the algorithm of sequential minimal optimisation. The computer program is developed in Borland C++ Builder environment. The excellent performances of our approach, high rate of successful pattern recognition and computational efficiency, make use of our tools possible in clinical practice. The system is tested at the Chair and Department of Internal Medicine and Cardiology, Central teaching Hospital in Warsaw, Poland.

The behaviour of Ant Colony Optimization (ACO) algorithms is studied on optimization problems that are composed of different types of subproblems. Numerically exact results are derived using a deterministic model for ACO that is based on the average expected behaviour of the artificial ants. These computations are supplemented by test runs with an ACO algorithm on the same problem instances. It is shown that different scaling of the objective function on isomorphic subproblems has a strong influence on the optimization behaviour of ACO. Moreover, it is shown that ACOs behaviour on a subproblem depends heavily on the type of the other subproblems. This is true even when the subproblems are independent in the sense that the value of the objective function is the sum of the qualities of the solutions of the subproblems. We propose two methods for handling scaling problems (pheromone update masking and rescaling of the objective function) that can improve ACOs behaviour. Consequences of our findings for using ACO on realworld problems are pointed out. © Springer-Verlag Berlin Heidelberg 2002.

Population based ACO algorithms for dynamic optimization problems are studied in this paper. In the population based approach a set of solutions is transferred from one iteration of the algorithm to the next instead of transferring pheromone information as in most ACO algorithms. The set of solutions is then used to compute the pheromone information for the ants of the next iteration. The population based approach can be used to solve dynamic optimization problems when a good solution of the old instance can be modified after a change of the problem instance so that it represents a reasonable solution for the new problem instance. This is tested experimentally for a dynamic TSP and dynamic QAP problem. Moreover the behavior of different strategies for updating the population of solutions are compared. © Springer-Verlag Berlin Heidelberg 2002.

Developing transferable skills in undergraduate mathematics students through mathematical modelling

teaching Mathematics and its Applications 2002年第1期21卷 29-45页

作者： Nyman, Melvin A. Berry, John Department of Mathematics and Computer Science Alma College Michigan United States Centre for Teaching Mathematics The University of Plymouth Devon United Kingdom

Undergraduate mathematics students should possess certain transferable skills upon completion of a degree. The Mathematical Association of America’s recently published CUPM Discussion Papers about Mathematics and the Mathematical sciences in 2010:What Should Students Know and the NCTM’s Principles and Standards for School Mathematics both suggest the importance of transferable skills for success in students’ later careers. These skills and a strategy for developing them via an intensive short course on mathematical modelling are discussed. Student reactions and comments on the course are included. The evaluation suggests that this course on mathematical modelling developed modelling as well as generic skills through the teaching, learning and assessment style. © The Institute of Mathematics and its Applications 2002.

32nd Annual Frontiers in Education;Leading a Revolution in Engineering and computer science Education

作者： Egbert, Dwight Bebis, George McIntosh, Meggin LaTourrette, Nancy Mitra, Aniruddha Computer Science Department University of Nevada Reno NV United States Excellence in Teaching Program University of Nevada Reno NV United States

We have developed a computer vision teaching module consisting of materials for two or three lectures and a final project for use in a CS1 programming course. The final project is to write an image processing program with applications in computer vision. The program will read in a two dimensional array of data from a file that represents a black and white photographic image, perform one or more transformations on the data and write the transformed data to a new file. A simple image viewer program is used to display the before and after images. In addition to learning more about programming it is the intent of the project that students also have some fun with images. Most students did indeed enjoy the visual nature of the project and were surprised that they could write a program to accomplish so much after just one programming course. A few students wrote very creative transformation functions. This CS1 module is one of several developed as part of a CRCD project, sponsored by NSF. The modules are available for free use or adaptation by other instructors and institutions.

Learning of class descriptions from class discriminations: A hybrid approach for relational objects 25th

25th Annual German Conference on Artificial Intelligence, KI 2002

作者： Geibel, Peter Schädler, Kristina Wysotzki, Fritz Methods of Artificial Intelligence Computer Science Department Technical University Berlin Sekr. Fr 5–8 Franklinstr. 28/29 BerlinD-10587 Germany Pace Aerospace Engineering and Information Technology GmbH Rotherstr. 20 BerlinD-10245 Germany

The paper addresses the question how learning class discrimination and learning characteristic class descriptions can be related in relational learning. We present the approach TRITOP/MATCHBOX combining the relational decision tree algorithm TRITOP with the connectionist approach MATCHBOX. TRITOP constructs efficiently a relational decision tree for the fast discrimination of classes of relational descriptions, while MATCHBOX is used for constructing class prototypes. Although TRITOP’s decision trees perform very well in the classification task, they are difficult to understand and to explain. In order to overcome this disadvantage of decision trees in general, in a second step the decision tree is supplemented by prototypes. Prototypes are generalised graphtheoretic descriptions of common substructures of those subclasses of the training set that are defined by the leaves of the decision tree. Such prototypes give a comprehensive and understandable description of the subclasses. In the prototype construction, the connectionist approach MATCHBOX is used to perform fast graph matching and graph generalisation, which are originally NP-complete tasks. © Springer-Verlag Berlin Heidelberg 2002.
