Pozycja Analysis of stability of the human gait.(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2007) Mrozowski, Jerzy; Awrejcewicz, Jan; Bamberski, PiotrAnalysis of the gait stability of a man moving along an even surface with a constant velocity is presented. The stability criteria applied to biped robots, namely: the Zero Moment Point (ZMP) and the Ground projection of the Center Of Mass (GCOM) have been employed in the investigations. The analysis has been carried out on the basis of measurement data obtained from the human gait recorded wit h a digital camera.Pozycja DSTA-2015 Conference Books vol. 1(Politechnika Łódzka.

Organization of the conference would not have been possible without a great effort of the staff of the Department of Automation, Biomechanics and Mechatronics. The patronage over the conference has been taken by the "Excellent Science" program of the Polish Ministry of Education and Science. It is a great pleasure that our invitation has been accepted by so many people, including good colleagues and friends as well as a large group of researchers and scientists, who decided to participate in the conference for the first time. With proud and satisfaction we welcome 748 authors from 52 countries all over the world. They decided to share the results of their research and many years experiences in the discipline of dynamical systems by submitting many very interesting papers. This booklet contains a collection of 364 abstracts, which have gained the acceptance of referees and have been qualified for publication in the conference edited books.[...]Pozycja Różne oblicza układów dynamicznych(Wydawnictwo Politechniki Łódzkiej, 2020) Mrozowski, JerzyMiędzynarodowa konferencja Dynamical Systems – Theory and Applicationsodbyła się po raz 15.

Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015) Biesiacki, Paweł; Mrozowski, Jerzy; Awrejcewicz, JanKnowledge of dynamic forces acting on the upper limb is useful, and sometimes even necessary, in its treatment and rehabilitation after injuries, during prostheses designing, as well as in optimization of the sports training process. In this work an attempt to determine the quantity of the inertia forces generated in forward fall has been undertaken. For this purpose a simplified mechanical model of the human body biokinematic chain has been prepared. Geometric data and mass of each element have been taken from anthropometric atlas for the Polish population. Kinematic data necessary to perform the analysis was calculated using fundamental laws of Mechanics. In this way accelerations of the selected points necessary for the determination of inertia forces acting on the individual links of the model were yielded. For validation of the obtained results a numerical model was constructed using SimMechanic module of the Matlab Simulink software. It made possible to compare the results obtained in both simulation methods. To make joints model more realistic a values of the viscous friction were assumed.
