We invite proposals for Special Sessions within a general scope of the conference.

Special Sessions supplement the regular program of DSTA 2021 and are intended to provide a sample of the state-of-the-art and highlight important research directions in a field of special interest to DSTA participants. Each of the sessions is expected to last 1.5 hours, counting 5 speakers to be invited by the organizers of the session. It is also possible to invite a multiple of this number (10, 15 speakers). In such case, the session is divided into parts, each counting 5 speakers. Presentations will be oral, and only by invitation of the session organizers. Both organizers and invited contributors will be required to register to the conference and submit their paper at the DSTA 2021 website, following the same deadlines as in the call for contributed papers. The review process will use the DSTA 2021 online system and will be fully supervised by the session organizers. All invited speakers will be provided with relevant certificates and submitted papers will be published in Springer Proceedings in Mathematics and Statistics or in a special issue of one of high-impact journals (see Journal Special Issues). Special Session organizers will benefit from 20% discount on the conference fee and relevant certificates.

Please note that in case less than 5 presentations are registered for the special session, the Chair of the conference and the Organization Committee reserve the right to re-assign these presentations into regular sessions.

If you are interested in submitting a proposal, please prepare a single PDF file containing the following information:

  • Title of the Special Session
  • Name of proposer(s) – max. 2
  • Email of the main contact person
  • Short (up to half A4 page) biography of the proposer(s)
  • Brief description of the motivation, highlighting the novelty/impact and timeliness of the topic
  • Relevance to the scope of DSTA and related topics
  • List of potential authors and tentative titles

The following sessions have already been accepted (by order of application):

No.: 1
Title: "Advances in fractional order calculus and applications"

  • Organizers: Carla Pinto, Instituto Superior de Engenharia do Porto (ORCID: 0000-0002-0729-1133 ); Cristina Muresan, Technical University of Cluj-Napoca, Romania
  • Fractional order differentiation is a generalization of classical integer differentiation to real or complex orders. In the last couple of decades, the use of fractional order calculus in modelling and control applications has seen a tremendous increase in research papers. This is mainly due to arguments recommending fractional calculus as an optimal tool to describe the dynamics of complex systems and to enhance the performance and robustness of control systems. Among these, fractional order PID controllers tuning, implementation and experimental validation occupy an important place. However, there are still many issues and open problems that need to be addressed in this area. This special session welcomes papers dealing with fractional calculus in modelling and control applications and aims at presenting some recent developments in this area of research. We welcome any contribution within the general scope of the Special Session theme.

No.: 2
Title: "Nonlinear behavior, performance, and control designs for complex structures in Civil, Aeronautical, Aerospace and Ocean Engineering"

  • Organizers: Jose Manoel Balthazar, Department of Mechanical Engineering, State University of Sao Paulo at Bauru, Baru SP, Brazil; Elżbieta Jarzębowska, Warsaw University of Technology, Power and Aeronautical Engineering Department, Institute of Aeronautics And Applied Mechanics, Warsaw, Poland; Angelo Marcelo Tusset, Department of Mathematics, Federal Technological University of Paraná, Ponta Grossa, PR, Brazil
  • The focus of this special session are discussions on modeling, performance, simulation, and control of dynamical behavior of complex mechatronic structures from but not limited to civil, aeronautical, aerospace and those related to ocean engineering, such as airplanes, rockets, satellites, ships, ground vehicles, underwater vehicles, offshore structures etc. Research from different aspects is welcome, for example how these problems can be understood and solved in view of numerical, computational, and theoretical approaches. Also, experimental investigations of these problems to validate mathematical and numerical models are very welcome.

No.: 3
Title: "Mathematical modeling of nonlinear systems involving interacting with medium"

  • Organizers: Marat Dosaev, Lomonosov Moscow State University, Russia; Yury Selyutskiy, Lomonosov Moscow State University, Russia
  • Interaction between rigid bodies and different types of media takes place in many problems applications pertaining to different areas of engineering. Mathematical simulation of effects (which are often highly nonlinear) resulting from such interaction is of both fundamental and application interest. The session will consider different problems in nonlinear dynamics of such systems, including dry friction and viscoelastic support effects in problems of contact between bodies, interaction between flow and bodies, mechanical behavior of molded composite material interacting with rigid walls, and so on. Construction of mathematical models and study of specific features of such dynamic systems is crucial for efficient design and control of the corresponding technical objects. Special attention will be paid to construction and analysis of closed semi-empirical dynamic models containing a small number of parameters. Questions of parametric optimization, bifurcations, damping or excitation of oscillations, control, stabilization of program motions and equilibria will be discussed.
