Please send me a list of your papers if they are relevant to this topic. A reduced bibliography will be published, and select papers from the bibliography will be considered for re-publication in a special Readings Collection. Here is a set of criteria for selecting the most appropriate papers: 1) Journal articles have preference. 2) The paper must deal with dynamical system models (not static). 3) Description of more than one model (ie., at least one qualitative and one quantitative) 4) Description of how to bridge the gap between/among levels/models. Thanks, and I look forward to receiving a list of publications. -paul f. +-------------------------------------------------------------------------+ | Paul A.

Please mail answers to jqrn@mi.aau.dk . --- When too much traffic are assigned to a network the objects are queing up, for example cars congested during morning peak-hour. Therefore some assignment models uses flow-dependent link costs when calculating the shortest path through the network. The models I know for describing these problems, are all analytical and rather cumbersome for practical purposes. Knowing a little about discrete-event simulating I wonder if it would be possible (or perhaps even easier...) to solve the problem using a simulation model, since all link flows then are known at any time - at least by the programmer :-} But I can't find any references to articles or books about this topic. If anyone could help me I would appreciate it.

The Conference is specifically focused on HDLs for electronic or optical circuits and/or systems. This includes the analog, microwave, digital and photonic/opto-electronic domains. The conference seeks a broad interpretation of the term ``hardware description language'' (HDL), intending to include a wide variety of notational techniques. This includes any formal notation such as: traditional HDLs, programming languages or environments, and graphical or tabular description methods. Most aspects of simulation involving HDLs are of interest, this includes but is not limited to: - Use of HDLs in multi-disciplinary simulation - Distributed and parallel simulation - Analog, digital, microwave, or optical system simulation - Continuous, compiled, or discrete event simulation - Integrating simulation with physical component execution - Hardware Acceleration - Impact of simulator performance on description methodology - Test and verification through simulation - Simulation accuracy and validation Prospective authors are invited to submit full papers (maximum of 15 pages double spaced) describing original and previously unpublished work for review by the program committee. Four copies of the manuscript should be submitted to the Program Chair by 6/15/93. Please include full name, affiliation, address, phone number, and e-mail address of each author and designate the author which is to be contacted. Authors must obtain employer, client, or governmental releases prior to submittal of final manuscript. The full paper will be contained in the conference proceedings which will be published by SCS. Accepted papers require paid conference registration fees with the camera-ready copy. Suggestions for panel discussions are also welcome. Proposals should include a title, abstract, biography of the panel organizer, and list of participants. Submissions of panel proposals should be received by the Program Chair by 7/2/93.

These standards are intended to meet the needs of large-scale Distributed Interactive Simulated (DIS) engagement systems, which are being used increasingly to support system acquisition, test and evaluation, tactical warfare simulation, and training in DoD. DIS is a tri-service initiative with funding from DMSO and STRICOM. The DIS Steering Committee has representatives from the Army, Navy, Marines, Air Force and other government agencies, as well as representatives from academia and industry. The purpose of the eighth workshop is to: Q Review the second draft of Version 2.0 of the PDU Standard Q Review the second draft of the Communication Architecture Standard. Q Review the second draft of the Fidelity Description Requirements Standard Q Review the second draft of the Exercise Control, and Feedback Requirements Standard. Q Review the protocol schemes for field instrumentation Q Review requirements related to the correlation of environment models. Q Continue defining requirements for linking DIS to other simulations.
