On the convergence of a finite-difference discretization à la Mickens of the generalized Burgers–Huxley equation
PublikacjaIn this note, we establish the property of convergence for a finite-difference discretization of a diffusive partial differential equation with generalized Burgers convective law and generalized Hodgkin–Huxley reaction. The numerical method was previously investigated in the literature and, amongst other features of interest, it is a fast and nonlinear technique that is capable of preserving positivity, boundedness and monotonicity....

STEROWANIE RAMIENIEM ROBOTA Z WYKORZYSTANIEM DANYCH Z KAMERY CYFROWEJ I MECHANIZMÓW SZTUCZNEJ INTELIGENCJI
PublikacjaPierwotnym zamysłem zespołu było stworzenie uniwersalnego systemu grającego w gry planszowe. Mierząc się z tym problemem, postanowiono zrobić jednak coś więcej - wywrócić dotychczasową koncepcję pracy użytkownika z komputerem „do góry nogami” i nie zmuszać użytkownika do nauki interfejsu, a zmusić system do współpracy z interfejsem, który rozumie użytkownik. Dokonane zostało więc przejście ze świata wirtualnego do świata rzeczywistego...
