Prof. Mirela Mazilu (Science Department Coordinator), Department of Geography made terrific efforts for the WSEAS conference. Professor Mazilu gave a short presentation regarding the role of the University of Craiova and in particular its objective of acting as a medium for transfer of knowledge amongst different partners, including academics and professionals. She also stressed the future applications of many research ideas developed in the event which are reflected in the growth of its Industrial Research Division. On the other hand, the work of WSEAS does not attempt to replace or compete with those of Universites but the WSEAS sees itself as complimentary to many different universities and organisations around the world. The conferences and publications programme of WSEAS provides an important mechanism to achieve this objective.

After the conference Prof. Mazilu sent an email to WSEAS: "It was a rare event, a "conference of friends," rare scientific quality that you are due to! The Conference logo was written with all natural flowers (chrysanthemum blue) as a modest tribute to the 15 years of excellent attach you are just a few memories of the soul, who had known of in Ghana related to Romanian hospitality ..
Thank you again wholeheartedly for the opportunity to demonstrate the great ability from Romanian science to create unique moments of excellence, people specialists, brand ... Within days, you get full DVD "TED living," a big event as the participants An unforgettable experience in years, in soul, in scientific CV, in every life... "

Dr. Florin Nedelcut (co-organiser) sent us this email

The WSEAS Conference in Drobeta Tr. Severin was a special  international conference, characterized by an atmosphere of hospitality and friendship. The works presented there were of a high level either from tourism, economy, mathematics or any related fields. Equally live and interesting were the discussions on the papers submitted.  The general impression we got after all was that Drobeta Tr Severin, with a modern faculty, with dedicated teachers and students, with hart full and efficient people was the best host for such an event, and a source of beautiful memories.

I say now "Thank You" to the organizers and I'm glad that together, we, the participants and organizers, wrote a page of scientific activity and made ​​friends and started collaboration.

Tensors or Folvecs, Folmats and Folarrs: Welcome to the Enchanted Realm of Linearity!

Professor Metin Demiralp
Principal Member of Turkish Academy of Sciences
Istanbul Technical University, TURKEY

Abstract: Linear algebra and its donations to us are beyond what we grasp. It presents many complete chapters although there is still room to plant new ideas, applications and facilities. It is basically constructed on one and two index arrays, namely vectors and matrices. However the power of representing almost everything in these items regarding their characters makes applied mathematics perhaps the most pleasent thing. Almost everybody tends to get help from linear algebraic tools even under storming clouds, like the nonlinearity, chaos, high multidimensionality and so on. Multidimensionality brings many difficulties to the handling of the arrays having more than two indices. A large group of applied mathematicians whose population is far beyond the estimations prefers to use the word “tensor” to cover the arrays having more than two indices. Despite its wide utilization this is not preferred by some other group of scientists including the speaker of this talk. Because “tensor” is, in its employment in continuum mechanics and physics, beyond an array which may have more than two indices. It defines a linear mapping which changes by a rule not depending on the coordinate system. This is not necessarily to be existing in all multilinear arrays. There are some other multilinear arrays which do not fulfill this condition. There are also two other words which are frequently used: “multiway array” and “multilinear array”. These might be more preferable. However there is a contradictory tendency to deal with multilinear arrays: unfolding which means to sort the elements in such a way that one or two indices suffice to represent the position in the final form after sorting. As long as a neat and unique procedure for the sorting operation is defined the reversion brings no problem and it is called folding. Unfolding and folding, they imply that the multilinear arrays can be considered either vectors’ or matrices’ folded forms and vice versa. This urges us to use the terms folvec (folded vector) and folmat (folded matrix) and (for both of them) folarr (folded array). The presentation will focus on certain issues related to these items and the linear algebra established over them. On the other hand, Singular Value Decomposition (SVD) arises at the focus as being most needed method to facilitate the use of multilinear arrays. Although this is valid in many senses SVD is not the elixir of life. It decomposes these items to rather simple components like one-rank orthonormal items. However there are some other novel approaches to orthogonally decompose these entities. High Dimensional Model Representation and recently developed Enhanced Multivariance Product Representation is amongst them. The presentation will also focus on these issues at certain level of details.

Keynote Speaker' Brief Biography: Metin Demiralp was born in Turkey on 4 May 1948. His education from elementary school to university was entirely in Turkey. He got his BS, MS, and PhD from the same institution, ?Istanbul Technical University. He was originally chemical engineer, however, through theoretical chemistry, applied mathematics, and computational science years he was mostly working on methodology for computational sciences and he is continuing to do so. He has a group (Group for Science and Methods of Computing) in Informatics Institute of ?Istanbul Technical University (he is the founder of this institute). He collaborated with the Prof. Herschel A.

Space Pruning Methods to Approximately Solve the Linear Boundary Value Problems ofOrdinary Differential Equations (ODEs) 

Professor N. A. Baykara
Marmara University, Mathematics Department
Abstract: The most important agents in the linear boundary value problems of ordinary differential equations (ODEs) are the differential operator and the boundary conditions. The complications basically arise from the boundary conditions since they enforce the two linearly independent solutions to be in harmony by creating appropriate forward and backward evolutions. That is, the matter is to match these evolutions such that boundary conditions are satisfied in total. These types of boundary value problems can be considered in two different categories, in one of which there is no arbitrary parameter to be determined but given inhomogeneity and the question is not far beyond an operator inversion problem. Whereas the other category problems are homogeneous in unknown functions and contains an arbitrary parameter to be determined. These cases correspond to the eigenvalue problems where the unknown function takes the role of eigenfunction while the arbitrary parameter is in charge of eigenvalue. The second category problems may gain more importance in applications like in quantum mechanics where the possible energies which are in fact eigenvalues are
sought and the corresponding eigenfunctions describe the nature of the wave function. One of the most important aspects of eigenfunctions is their closednesses under the action of the differential operator of the problem. In other words the image of the eigenfunction under any nonnegative number of consecutive actions of the relevant differential operator satisfies the boundary conditions as the eigenfunction itself does.
The differential operator of the boundary value problem acts on functions which can be considered lying in an appropriately defined Hilbert space. They map from this space to the same space. This space’s members should satisfy the boundary conditions individually. As long as we do not know the solution of the boundary value problem we do not know the explicit structures of the eigenfunctions. However, if we would know them then each of them would conserve the property of satisfying the boundary conditions in their images under any nonnegative power of the differential operator. Therefore one can start with a set of functions in this space and then consider all the possible linear combinations satisfying the boundary conditions under the action of the differential operator. This imposes just a single condition on the linear combination coefficients. The other conditions arise from the enforcements to make the linear combination satisfying the boundary conditions under the powers of the differential operator, second, third and so on. This approach changes the basis set towards the true eigenfunction set and the infinite limit is expected to get exact match. Sufficient care must be taken about the singularity issues. The presentation will involve most important aspects as milestones of this issue.
