WSEAS Post Conference Report, Dallas, Texas, USA, March 22-24, 2007

* 11th WSEAS International Conference on APPLIED MATHEMATICS (MATH '07)
*  6th WSEAS Int.Conf. on SIGNAL PROCESSING (SIP '07)
Symposium on Management, Marketing and Finances (MMF '07)
    * Symposium on Wavelets Theory & Applications in Applied Mathematics, Signal Processing & Modern Science (WAVELETS'07)

The additional features of this multiconference were
1) Publication of the Proceedings in 3 media: hard-copy, CD, E-Library
(A) Books in the Applied Mathematics Series of the WSEAS  and Books in Electrical and Computer Engineering Series
(two volumes, see photos of the cover below) with ISBN and ISSN indexed by the major Citation Indexes:

(B) CD-ROM Proceedings with pages' numbers with ISBN and ISSN indexed by the major Citation Indexes:

(C) E-Library:

and possible:

JOURNAL PUBLICATION: Only authors of high - quality papers of archival value (they have been recommended by the Chairmen) have been invited (after the end of the conference) to send extended versions of their papers to the international WSEAS Journals after the conference. See the procedure below.

2) WSEAS gave a very strong and important tool to all the participants:
A new username and password WITHOUT EXPIRY DATE for on-line access in the WSEAS Conference proceedings FOR EVER.

3) WSEAS gave also in the  CD-ROM the Proceedings of the previous conferences also from Texas (November of 2006). So, the participants were really very happy, because they had the opportunity to study the proceedings of the previous year.

4) Because the WSEAS will maintain the same policy in 2008, the accepted and presented papers will be available and readable in the CD-ROM that we will distribute in Cambridge, USA in April and May of 2008. See:

5) Rich cultural and social part as usual in WSEAS events. The importance of these conferences can be proved by the impact of these conferences in 2006: See, please

6) The conference Books (Hard-Copy Proceedings), CD-ROM proceedings and (Journals with selected papers) published by WSEAS Press continue to sell for a long time after the meeting has taken place. This is another demonstration of the prestige the scientific community attribute to the meetings organised by the WSEAS.

Scientific Aspect

.: What is the Permanent Procedure for additional Journal publication for a very small number of High-Quality Papers presented in the WSEAS Conferences in Dallas (after the recommnedation of Chairmen).

                                                                                                                                                          April 30, 2007

Dear Authors of papers that were presented in the WSEAS Conferences in Dallas, Texas, USA

We have started now the evaluation of extended versions of your papers for possible inclusion in WSEAS journals after new review.

INTRODUCTION: You know that our goal is to maintain very strong international journals, to increase the impact of our beloved WSEAS Transactions, really top journals as they really are. To this end, we need only high quality papers, breakthrough works of archival value, i.e. papers  that are well written from any point of view, completed studies (with their numerical examples or experiments that must be compared with the previous results in the literature), excellent english and of course correct WSEAS format. The papers also must be substantially extended version of the paper that was presented in the conference (with more than 40% new material). We need papers that will attract the attention of other scholars citing them increasing our impact. In the next few years, the WSEAS transactions must be in every academic library, in every corner of the earth. To this end, we need your high quality contribution.

a) Check very carefully if your idea is really important, breakthrough in your field and can appear in a Journal of the quality and the level of the WSEAS Transactions.
If you doubt, do not send it so easily. Your paper must not be only a good idea. It must be a complete study with theoretical background, complete bibliographical references; without grammatical and syntactical errors. For theoretical works: full comparison with previous published papers is necessary. We need numerical examples, applicability of the method,
originality, novelty and directions for future research. For experimental or computational works: full comparison with previous published papers is necessary. We need real experiments with the necessary
documentation, while for computational work, we need full benchmarks. Of course along discussions for the applicability of the method, originality, novelty and directions for future research.

b) Complete the extended version of your paper until June 30 and send it until June 30, by email to me
You must receive an email notification from us. Use only the email address: selected_papers_texas (AT),  replace (AT) with @

c) If your extended version fulfills the paragraph a), then we will send it to 3 independent Reviewers outside
 your country. If not, we are entitled to reject it from this early stage informing you properly. The positive answer of the 3 reviewers is necessary (attention: 2 yes and 1 no implies NO, i.e. rejection).

d) We will collect the reviewers' remarks and will send them again to you for acceptance/ acceptance after minor revision / acceptance after major revision / rejection

e) Possibly new rounds of review will be needed.

f) No additional fee is needed in case of acceptance.

After all this procedure, the accepted papers that come from WSEAS Conferences in Texas will be published in
* WSEAS Transactions on MATHEMATICS
* WSEAS Transactions on COMPUTERS

IF: you want another journal, or if you miss the deadline of June 30, or if your paper was not presented in the WSEAS Conferences, THEN: you can upload it quite independently as regular paper from the WSEAS Site for the Journals: 

The final list of the papers must have the approval of an Associate Editor, 3 Reviewers, and of course the Editor-in-Chief of the particular Journal. i.e. 5 persons: 3 Reviewers, Guest Editor and the Editor-in-Chief of the particular Journal. We hope to help to to maintain the WSEAS Transactions, top journals

Fluctuation Expansion at the Horizon as a new and Efficient Tool for Integration and ODE and PDE Solving

Abstract: The univariate integration of a function over a closed interval can be realized through various analytical or numerical methods. Almost all numerical methods assume the continuity and the smoothness of the function under consideration and tries to use somehow a polynomial approximation. They fail if the function has nonintegrable singularity in the integration interval. In the case of integrable singularities in the interval the numerical methods may become slowly converging. They may be negatively affected even from the singularities outside the integration domain. Hence, to remove or to decrease these types of negative effects, one can use a weight function which somehow reflects and compensates the singular nature of the function to be integrated.
Fluctuation expansion uses sharply localized weight functions representable by Dirac's delta function which picks the value of a function at a given point. Dirac’s delta function can be approximated by appropriately defined projection operator kernels. Fluctuation expansion is based on these types of approximations. It expands and approximates the weight function in this way and produces a Gauss quadrature like approximation formula with universal weight coefficients which are different for different weights. The accuracy can be controlled by monitoring the number of the terms in expansion of weight in terms of projection operator kernels.
Fluctuation expansion can also be applied to multivariate integration. The basic philosophy remains same in this case. Only difference is the multivariance in various entities and as long as sufficient care is paid for possible complications the efficiency is again powerful and the method remains promising.
All linear partial differential equations describing probabilistic events can be handled by using fluctuation expansion. This is because of the fact that the existence of probability in the event description implies the utilization of the expectation values like in quantum mechanics or nonequilibrium statistical mechanics via Liuouville equation. If the expectation values are considered instead of the probability describing entities then the multivariate integrals in the representations of expectation values can be approximated by using the fluctuation expansion.


Incomplete inventory information - the next challenge

Abstract: The purpose of this lecture is to review recent developments in the analysis of partially observed optimal control problems that arise in the management of inventory systems.
Inventory control is one of the most important topics in management science/operations research. A systematic analysis of inventory problems began with the development of the classical EOQ formula of Harris in 1913. Since then, an enormous amount of literature has accumulated on inventory control problems.
One of the critical assumptions in this vast literature has been that the current level of inventory is fully observed. Some of the most celebrated results such as optimality of base-stock or (s,S) policies have been obtained under the assumption of full observation. Yet it is often the case in practice that the inventory level is only partially observed. Most of the well-known inventory policies are not only non-optimal, but are also not applicable in the partial observation environment.
The reasons for partial observation of the current inventory level are many. Inventory records or cash register information differ from actual inventory because of a variety of factors including transaction errors, theft, spoilage, misplacement, unobserved lost demands, and information delays. As a result, what are usually observed are some events or surrogate measures, called signals, related to the inventory level. At best, these relationships may provide only the distribution of current inventory levels.
In the best case, therefore, the relevant state in the inventory control problems is not the current inventory level, but rather its distribution given the observed signals. Thus, the analysis for finding optimal production or ordering policies takes place generally in the space of infinite-dimensional probability distributions.


Social Aspect

Coffee-Breaks: The WSEAS Organizing Committee offered 6 very rich coffee-breaks. Each coffee-breaks were composed by filter coffee, decaf. coffee, tea, local sweets, biscuits, freshly baked pastries. During the Coffee-Breaks the attendees had several opportunities for to interchange ideas and proposals for common projects and collaboration.

Banquet: The Conference Banquet took place inside the hotel.
The whole event was really impressive. All the participants had a very good time and enjoyed themselves very much.
Several post-conference excursions took place.
