Toward Human Chromosome Knowledge Engine
PublikacjaHuman chromosomes carry genetic information about our life. Chromosome classification is crucial for karyotype analysis. Existing chromosome classification methods do not take into account reasoning, such as: analyzing the relationship between variables, modeling uncertainty, and performing causal reasoning. In this paper, we introduce a knowledge engine for reasoning-based human chromosome classification that stores knowledge...

Mathematical Approach to Assess a Human Gait
PublikacjaA purpose of the paper was to create a mathematical approach to assess a human gait. The scope of the study was to model a normal gait in the sagittal plane and frontal plane of the body. Applying the Newton-Euler formulation, three multibody biomechanical models were derived to describe single support phase and double support phase of the gait. To model a gait in the sagittal plane the open-close sagittal 6DOF model and the open-close...

Model of human psychology for controlling autonomous robots
PublikacjaReferat przedstawia model umysłu, uzyskany w oparciu o wiedzę na temat ludzkiej psychologii, służący do sterowania systemami autonomicznych robotów. Systemy poznawczy i motywacyjny (emocje i potrzeby) stanowią jego główne części. System motywacyjny kontroluje reakcje robota w oparciu o zmienne stanu potrzeb. Z drugiej strony, emocje nadzorują i zmieniają/modyfikują zachowanie robota poprzez zmianę pewnych parametrów uwzględnianych...
