By applying the entropy-stabilization engineering strategy, we developed ultrastable metal oxide nanotube arrays consisting of multiple oxide constituents by anodic oxidation of high-entropy alloy precursors, which can sustain 800 °C heat-treatment without crystallization and resist 1000 °C calcination without collapse.
Because of economic significance of state variable in economic dynamical systems, the values of state variables are positive due to capacity constraints and financial constraints, we can control chaos by adding upper bound or lower bound to state variables in economic dynamical systems, which is different from the chaos stabilization in engineering or physics systems.
Fractures are fundamental structures in the Earth's crust and they can impact many societal and industrial activities including oil and gas exploration and production, aquifer management, CO2 sequestration, waste isolation, the stabilization of engineering structures, and assessing natural hazards (earthquakes, volcanoes, and landslides).
The time delay phenomenon may be encountered in many practical systems such as the AIDS epidemic, aircraft stabilization, chemical engineering systems, inferred grinding model, manual control, neural network, nuclear reactor, population dynamic model, rolling mill, ship stabilization, and systems with lossless transmission lines.
Despite advanced stabilization technology, shaking does happen.
Furthermore, an engineering stabilization problem is also presented where numerical simulation case study confirmed the findings.
In control engineering, stabilization is usually achieved by the use of feedback.
Based on the results, we propose suitable sand control measures that combine blocking of the moving sand with stabilization, initially using engineering measures then concluding with biological measures.
An extensive laboratory investigation has been carried out to assess the potential use of polymeric stabilization in improving engineering properties of three soil types for use in foundation layers of flexible pavements.
