Case studies can significantly contribute towards improving the understanding of formalisms and thereby to their applicability in practice. One such case, namely a cascade of the familiar 24-hour timers (in suitably generalized form) provides interesting gedanken experiments and illustrations for presenting, illustrating and comparing various formalisms for modelling real-time behaviour of syst...

We derive the probability for rapidity gaps in a parton cascade and investigate the dual connection with hadronic final states. A good description of observations in ee-annihilations is obtained by perturbative QCD calculations in MLLA using previously determined parameters (QCD scale Λ and kT -cut-off Q0) and applying the parton hadron duality picture. Further predictions are derived; especial...

the ball and beam system is one of the most popular laboratory setups for control education. in this paper, we design a fuzzy pd cascade controller for a ball and beam system using asexual reproduction optimization (aro) technique. the ball & beam system consists of a servo motor, a grooved beam, and a rolling ball. this system utilizes a servo motor to control ball’s position on the beam. chan...

A significant result in the structure theory of regular languages is the Krohn-Rhodes Theorem, which states that any finite automaton can be decomposed into simple “prime factors”. This theorem can be stated in different versions using different products on different structures, namely the cascade product of automata, the wreath product of transformation semigroups and the block product of semi...

Abstract We describe an activity developed as laboratory at home during the pandemic period by which it is possible to investigate numerically and experimentally a harmonically driven pendulum with variable frequency. realized prototype using LEGO ® bricks EV3 motor. Because undergoes large amplitude oscillations, motion has been studied implementing non-linear numerical model in Python. Studen...

in this paper, considering the importance of incoming flow turbulence intensity into combustion chamber, tripping wire effect on the flow wake has been experimentally investigated within a linear compressor cascade. to do this, two wires were implemented along each blade and their effects on average velocity, turbulence intensity and vortices frequencies at reynolds number 45500 were accurately...
