Control and controllability of microswimmers by a shearing flow [PDF]
Royal Society Open Science, 2021 With the continuing rapid development of artificial microrobots and active particles, questions of microswimmer guidance and control are becoming ever more relevant and prevalent. In both the applications and theoretical study of such microscale swimmers, control is often mediated by an engineered property of the swimmer, such as in the case of ...

Investigation of Aeroelasticity Effect on Missile Separation from the Internal Bay
International Journal of Aerospace Engineering, 2023 There is a strong aerodynamic interference when launching the missile in the embedded mode. During the separation process, the carrier aircraft safety may be threatened due to large slenderness ratio, low structural stiffness, and aeroelasticity effects ...

Flow Rate Control by Means of Flow Meter and PLC Controller [PDF]
Sensors, 2021 This paper presents a design of a flow meter based on a programmable logic controller (PLC). The new construction of a flow meter controlled by PLC increases the possibilities for the control and automation of fluid flow. Additionally, the didactic potential of the use of simple automation in the form of a programmable logic controller was considered ...

Causality & Control Flow [PDF]
Electronic Proceedings in Theoretical Computer Science, 2019 Causality has been the issue of philosophic debate since Hippocrates. It is used in formal verification and testing, e.g., to explain counterexamples or construct fault trees. Recent work defines actual causation in terms of Pearl's causality framework, but most definitions brought forward so far struggle with examples where one event preempts another ...
