The Mohe–Daqing oil pipeline (MDOP) of China–Russia crude oil pipeline (CRCOP) goes through a 441 km permafrost in high-latitude regions, the most critical problem of which is the thawing settlement of the oil pipe. Global warming effect, oil temperature,... see more

The physical mechanisms have been investigated that form and transform the corpuscular-vortex-wave thermal complexes of disturbances in contact tribosystems based on the quantum-mechanical exchange interaction. The presence of a contact gap determines the... see more

The thermal needle probe method, which is widely used for measuring the thermal conductivity ? of soils, deploys a long and thin metallic probe that houses a line heater and a temperature sensor. However, inserting such probes into consolidated or densely... see more

This paper describes the most significant sources of errors and disturbance when measuring temperature and humidity with a glider. Measurement flights have started from different airports in Germany, between April and August of 2018, resulting in a c... see more

The multi-tank-series system could come up the problem of instability due to dead-time. The goals of this work are to study the dynamic behavior of Two-Thermal-Tanks-Series (TTTS) with dead time through the open loop experiment in laboratory, and to propo... see more

In this work, we have modified an existing experimental setup to fully classify the thermal effects on a laser beam propagating in air. Improvements made to the setup include a new, more powerful laser, a precision designed turbulence delivery system, an ... see more

In this paper, a comparison between conventional RST polynomial control by poles placement and RST flatness-based control is proposed. These approaches were developed, in discrete-time formalism by carrying out a generation of a reference starting from a ... see more

A clustering method is an effective way to select the proper temperature sensor location for thermal error modeling of machine tools. In this paper, a new temperature sensor clustering method is proposed. By analyzing the characteristics of the temperatur... see more

A solar dedicated ventilation system based on active disturbance rejection controller (ADRC) has been designed in this study and tested by experimental research to acquire better control accuracy and energy-saving potential compared with former systems. T... see more
