We consider the idea of controlling the evolution of a membrane system. In particular, we investigate a model of membrane systems using promoted rules, where a string of promoters (called the control string) “travels” through the regions, activating the rules of the system. This control string is present in the skin region at the beginning of the computation – one can interpret that it has been...

Patient motion during treatment is one of the future challenges in the field of external beam radiotherapy. In this paper, we address this problem by considering a time–dependent Boltzmann transport model for dose calculation and by deriving closed-loop control laws for the treatment planning problem. We formulate an optimal control problem for the desired dose using boundary and distributed co...

results the hemostatic time of aluminum chloride 50%, 25%, 15%, 10% and 5% were 8.20 ± 0.919, 14.10 ± 1.37, 21.20 ± 1.31, 30.80 ± 1.68 and 42.00 ± 4.19 seconds, respectively. also, the mean hemostasis time in the control group (suture) was 84.00 ± 4.05 seconds. the hemostatic times of different concentrations of aluminum chloride were significantly less than that of the control group. there was...

Controlling parameters is a necessity in every non-trivial application. We present a pattern that aids in decoupling external control mechanics from the internal component structure, while supporting the automatic mirroring of internal structure into external representation. Furthermore, we show how to use this pattern in the implementation of a C++ component for stream-based control that has b...
