The Compositional Construction of Markov Processes [PDF]

open access: yesApplied Categorical Structures, 2010
We describe an algebra for composing automata in which the actions have probabilities. We illustrate by showing how to calculate the probability of reaching deadlock in k steps in a model of the classical Dining Philosopher problem, and show, using the Perron-Frobenius Theorem, that this probability tends to 1 as k tends to infinity.

Temporal variation laws of longitudinal stress on cross section of shield tunnels

open access: yesYantu gongcheng xuebao, 2021
The longitudinal stress acting on the cross section of shield tunnels will affect the waterproof properties of the segments and the stiffness of the circumferential joints, which will thus affect the development trend of the longitudinal nonuniform ...

Simultaneous immobilization of heavy metals and nutrient elements in contaminated sediment using a novel composite agent product

open access: yesWater Science and Technology, 2023
In this research, an innovative type of sediment resource treatment agent (SRA) was synthesized successfully, which could immobilize ammonia nitrogen (NH3-N), total phosphorus (TP), potassium (K), and simultaneously stabilize cadmium (Cd), lead (Pb ...
