Calculation of Dune Profile Changes Generated by Hurricane: Preliminary Results

Szmytkiewicz P., Szmytkiewicz M., Schönhofer J., Morawski J., Malicki J.

Archives of Hydro-Engineering and Environmental Mechanics

2018

Vol. 65, nr 3

221--239

The paper presents the main theoretical concepts related to methods of calculating the erosion rate for sandy dunes on natural coasts, namely, the beach equilibrium profile and incident waves. To illustrate calculations of dune erosion in the vicinity of the Coastal Research Station (CRS) in Lubiatowo, the Xbeach model (an incident wave model) was used. The calculations were carried out for hydrological and hydrodynamic conditions that accompanied Hurricane Ksawery (December 6–8, 2013). The results of the calculations were compared with the measured data. A satisfactory agreement was obtained between the predicted and measured results.

Bionics and systems theory approach to the investigation of human gait

Morawski J.

Acta of Bioengineering and Biomechanics

1999

Vol. 1, nr 1

37-46

Advantages of system-theoretic, bionics, and cybernetics approach to the investigation of human gait have been proved. The complete motion act has been considered in multi-level hierarchical organization. As an example, two sequential levels have been analyzed: gait techniques and gait tactics. Gait heading control has been considered in brief. Natural sources of the so-called locomotion rhythms have been explained.
