Orlande Chairman for the 4icipe General Announcement And Call for Papers Abstracts due: October 05, 2001 4th INTERNATIONAL CONFERENCE ON INVERSE PROBLEMS IN ENGINEERING: THEORY AND PRACTICE May 26-31, 2002 Angra dos Reis, Brazil http://www.lttc.coppe.ufrj.br/4icipe/ e-mail: icipe@lttc.coppe.ufrj.br CONFERENCE SYNOPSIS The 4th International Conference on Inverse Problems in Engineering: Theory and Practice belongs to a successful series of United Engineering Foundation conferences held in a three-year cycle. Previous conferences took place in Palm Coast, Florida (1993), Le Croisic, France (1996) and Port Ludlow, Washington (1999). The conference has its roots on the informal seminars organized by Prof. J. V. Beck at Michigan State University, which were initiated in 1987. CONFERENCE SCOPE The main objective of the conference is to bring together researchers from different world regions, dealing with different inverse problem applications and with its theoretical aspects, for the presentation of their most recent research results and for the technical discussion of their findings. Despite traditionally having the heat transfer community as the leading organizing group, such conference reaches a much broader scope; its hallmarks are the multidisciplinary nature and the innumerous opportunities for technical interactions among the participants. The conference will emphasize a broad range of deterministic, statistical, mathematical, computational and experimental approaches, which can be applied to the solution of inverse problems and to the design of experiments. The topics listed below give a general guideline for possible contributions: Acoustics Vibrations and structural dynamics Electromagnetism Nuclear transport Geophysics Inverse design and optimization Imaging Design of experiments Heat and mass transfer Property estimation Fluid mechanics Signal and noise processing Solid mechanics Benchmark results Tomography and inverse scattering Novel inverse methodologies Porous media Theoretical and mathematical aspects Contributions dealing with practical applications of inverse problems are encouraged, such as in petrochemistry, aeronautics, astronautics, medicine, groundwater flow, materials processing, remote sensing, non-destructive evaluation, etc. SUBMISSION, SELECTION, PUBLICATION AND PRESENTATION OF CONTRIBUTED PAPERS Original papers are invited on the above general topics. Authors should submit a one-page abstract by October 05, 2001, through the United Engineering Foundation web-site (http://www.engfnd.org/2ai.html). If you have any difficulties to submit the abstract electronically, please send it by express-mail to the conference chair. Authors whose abstracts are accepted will be sent the Author's Kit, which will include detailed instructions for the preparation of their manuscripts. The papers submitted will be evaluated by two competent reviewers in the area. Only the accepted papers that are effectively presented in the conference will appear in the proceedings. The proceedings will be published as a bound volume and sent to the conference participants through airmail within four months after the conference is finished. A book of abstracts and a CD-ROM containing all accepted papers will be available for the participants during registration. Authors may consider their papers for further review and possible publication in the journal Inverse Problems in Engineering (http://www.gbhap.com/journals/210/210-top.htm). When submitting the full papers to the conference, the authors should indicate if they want to submit the papers to the Inverse Problems in Engineering journal as well. In this case, the review process will be more stringent and a third evaluation of the paper will be requested. The conference will be organized in the traditional United Engineering Foundation format. Daily oral and poster sessions will be held in the mornings and evenings. Afternoons will be free for recreation and technical interactions among the participants. Tutorial sessions will be scheduled and keynote lecturers from different research fields will be invited.

ENGINEERING FOUNDATION CONFERENCES United Engineering Foundation Conferences were established in 1962 to provide an opportunity for the exploration of problems and issues of concern to engineers from many disciplines. The format of the Conference provides morning and evening sessions in which major presentations are made. Time is available during the afternoons for ad hoc meetings and informal discussions and is designed to enhance rapport among participants and prompt dialogue on the developments of the meeting. We believe the Conferences have been instrumental in generating ideas and disseminating information to a greater extent than is possible through more conventional forums. All participants are expected to contribute actively to the discussions. UNITED ENGINEERING FOUNDATION FELLOWSHIPS FOR NEW PROFESSIONALS The United Engineering Foundation sponsors a Conference Fellowship program. Applicants are limited to those currently active in engineering or related professions with a direct interest in the conference topic. They must be within ten years of their B.Sc. degree at the time their applications are submitted. The stipend is sufficient to cover the conference registration fee and on-site room and board. Transportation expenses are not included. Application information may be obtained from the UEF Web site (www.engfnd.org) or by fax from the Foundation (1-212-591-7441) and must be submitted by February 26, 2002. VENUE The location for the conference will be Hotel Portobello Resort & Safari (http://www.hotelportobello.com.br) in Angra dos Reis. The resort is located between the mountains of Serra do Mar and the bay of Angra dos Reis, providing a unique and safe atmosphere for the conference participants. All apartments of this five-star hotel face a private beach. Schooners and motorboats are available in the resort for tours to countless islands that dot the bay. Swimming pools, tennis courts, windsurf, kayaks, jet-skis, horseback rides and trekking are also available. In a farm inside the resort you can come across exuberant Brazilian fauna and flora in the tropical rain forest. The conference site is located about 100 kilometers (70 miles) from the Rio de Janeiro International Airport, in the south coast of the state of Rio de Janeiro. For the conference participants, the destination shall be the Rio de Janeiro International Airport. It is served by major airline carriers, with everyday flights from many cities in North America, Europe and Asia. Most international flights arrive in Rio de Janeiro in the morning. Transportation will be provided by the organization from the Rio de Janeiro International Airport to the conference site on Sunday morning (May 26) in air-conditioned buses or vans, with bilingual guides. Also, transportation from the conference site to the Rio de Janeiro International Airport will be provided for the conference participants and guests on the last day of the conference (May 31). Pre- and post-conference tours for the city of Rio de Janeiro or other Brazilian cities are available. For more details on tours and on air transportation discounted tickets, please contact the official travel agent for the conference, KSK Tours (http://www.ksk.com.br).

Thanks to the development of computation capabilities, it has become of common use in applications such as non destructive testing, control of industrial processes, identification of parameters, medical imaging, industrial design, etc. Scientists interested in these topics are coming from mathematical, engineering and scientific computation backgrounds, as well as from various applications fields. Designing fast algorithms to solve such problems is one of their major concerns. The first International Conference on Inverse Problems, Control and Shape Optimization (IPCSO'98) was held in Carthage (Tunisia) in April 1998. It was organized by ENIT, INRIA and UTC. More than 80 participants attended, including 30 invited speakers. Some of the questions discussed during the conference have given place to the release of a special section in the " Inverse Problems " journal (Vol 15, No. 1, February 1999). Besides, the conference allowed the local organizing team to establish new international links, some of them having already given birth to steady cooperations. This success has drawn the organizers to organize a second edition, to be held in the same wonderful place, the "Palais de Be=EFt El Hikma" that shelters the Tunisian Academy of Sciences, Letters and Arts. PICOF'02 is expected to gather 150 participants, including around 60 invited speakers. Invited speakers R. Aboula=EFch (Rabat), G. Allaire (Palaiseau), C. Alves (Lisboa), S. Andrieux (Paris), A.
