This paper describes a haptic simulator that has been developed as an aid for the sensorimotor skill acquisition in dentistry. An important feature of the simulator is the ability to generate templates of position and force trajectories for the students to follow. Furthermore, the simulator has a mechanism, haptic playback, to help the students follow and(More)
Existing penalty-based haptic rendering approaches compute penetration depth in strictly translational sense and cannot properly take object rotation into account. We aim to provide a theoretical foundation for computing the penetration depth on the group of rigid-body motions SE(3). We propose a penalty-based six-degrees-of-freedom (6-DOF) haptic rendering(More)
This paper is focused on investigating force regulation strategies employed by human central nervous system (CNS). The mechanism responsible for force control is extremely important in people's lives, but not yet well understood. We formulate the general model of force regulation and identify several possible control strategies. An experimental approach is(More)
SUMMARY Existing penalty-based haptic rendering approaches are based on the penetration depth estimation in strictly translational sense and cannot properly take object rotation into account. We propose a new six-degree-of-freedom (6-DOF) haptic rendering algorithm which is based on determining the closest-point projection of the inadmissible configuration(More)
The influence of new exopolysaccharide, synthesized by Candida tropicalis and Pseudomonas sp. consortium in ethanol, on the animal body was studied in chronic experiments conducted in 200 non-inbred white rats. The animals were sacrificed after 3, 10 and 18 months of follow-up. The results of the investigations permit a conclusion that exopolysaccharide(More)
The authors studied the epidemiological situation in a surgical clinic on the basis of examination of 12,000 case histories in the course of several years. Microbiological examinations were carried out of 1438 samples with the purpose of assessing the microbial picture of the wounds of patients and all factors of the environment which could participate in(More)
The authors present the results obtained in the survey of graduates from the sanitary and hygienic departments of 4 medical institutes of the Ukrainian SSR carried out in a special pedagogical experiment with the aim to determine the "survival" of their knowledge in epidemiology. As a result, variations in the stability of knowledge in different branches of(More)
