We experimentally study the dynamics of active particles (APs) in a viscoelastic fluid under various geometrical constraints such as flat walls, spherical obstacles and cylindrical cavities.We observe that the main effect of the confined viscoelastic fluid is to induce an effective repulsion on the APs when moving close to a rigid surface, which de
This paper presents a novel steering mechanism embedded in a point-the-bit rotary steerable system (RSS) for oilfield exploitation.The new steering mechanism adopts a set of universal joints to alleviate the high alternative strain on drilling mandrel and employs a specially designed planetary gear small tooth number difference (PGSTD) to achieve d
An extended nonlinear disturbance observer (ENDOB)-based fuzzy sliding Bread mode control approach is proposed for single-input and single-output systems with matched and mismatched uncertainties/disturbances, and it is extended to the general $n$ th order systems.By integrating the mismatched disturbance estimation and its derivative into the slid
Multiple wire twisted steel strands are commonly used to hoist elevators, concrete structures, etc.Due to frequent and long-time usage, the steel strands are subjected to corrosion, overloads, and aging, making strands may fail unexpectedly.Hence, the health monitoring of steel strands becomes more important to avoid the sudden collapse of hoisting
