This study is devoted to providing predictions of the pull-in parameters (pull-in voltage and pull-in displacement) of electro-statically actuated micro-beams based on a continuous model using Genetic Algorithm (GA) technique. A phenomenon in which the actuated electrode comes in direct contact with the fixed electrode due to the electrostatic force is called pull-in instability. Accurate deter...

Abstract Silicon carbide whiskers (SiCw) have many excellent properties such as high strength, elastic modulus, and temperature resistance. In this paper, by using water reducer dispersant, a stable SiCw dispersion was obtained, SiCw-modified cement-based composites were prepared. Tensile strength tests for 8-shaped specimens carried out on the materials. The fracture of materials measured thre...

Functional clustering of neurons is frequently observed in the motor cortex. However, it is unknown if, when, and how fine-scale (<100 μm) functional clusters form relative to voluntary forelimb movements. In addition, the implications of clustering remain unclear. To address these issues, we conducted two-photon calcium imaging of mouse layer 2/3 motor cortex during a self-initiated lever-pull...

Single-well reactive tracer tests, such as the push-pull test are useful tools for characterising in-situ bioattenuation processes in contaminated aquifers. However, the analytical models that are used to interpret push-pull data may be over-simplified, and potentially overlook important processes responsible for the frequent discrepancy between predicted and observed results obtained from push...

The selection of pull strategy or push strategy for specific products depends on not only the change of demand, but also the importance of scale economy for production and distribution. In fact, almost no complete pull strategy or complete push strategy is adopted from begin to end in practice, and in most cases, the combined push-pull strategy is adopted in a marketing process. This paper will...
