Machine learning approaches can serve as powerful tools in the machining optimization process. Criteria, such accuracy and stability, are important to consider when choosing among different models. For industrial application, it also is essential balance cost, applicabilities, ease of implementations. Here, we develop Gaussian process regression models for predicting main cutting force (R) its ...

In design and analysis, standard references assume the pedestrian flow as unidirectional. In reality however, pedestrian flow is usually bi-directional. The main question pursued in this paper is that whether the main characteristics of pedestrian flow the same under uni- and bi-directional conditions. In order to achieve this goal, effect of bi-directional stream is inv...

Elliptic curves find numerous applications. This paper describes a simple strategy to speed up their arithmetic in right-to-left methods. In certain settings, this leads to a non-negligible performance increase compared to the left-to-right counterparts.
