Part 2: pushing the envelope. A process perspective for architecture, engineering and construction [PDF]

open access: yes, 2015
In this article, I am building on an emerging 'process view of nature' and how biological membranes emerge through the combined action of (locally) autonomous construction agents.

Design of variable frequency control system for local ventilator based on fuzzy theory

open access: yesGong-kuang zidonghua, 2022
The existing variable frequency control method for local ventilator lacks prediction of gas outburst variable. When a large amount of gas emission abnormally, there is a certain lag in regulation, which is easy to lead to gas accumulation.

Proportional-integral-plus control applications of state-dependent parameter models [PDF]

open access: yes, 2007
This paper considers proportional-integral-plus (PIP) control of non-linear systems defined by state-dependent parameter models, with particular emphasis on three practical demonstrators: a microclimate test chamber, a 1/5th-scale laboratory ...

Research on the influence of roadway obstacles on the position of wind speed monitoring

open access: yesGong-kuang zidonghua, 2023
The existing high-precision wind speed sensors are uniformly installed in the coal mines under normal airflow conditions. It does not consider the abnormal airflow caused by obstacles placed in the roadway.
