This study intends to evaluate the rear-end collision risk under fog conditions considering reduced visibility by introducing a new algorithm. Based on the proposed algorithm, the minimum stopping distance of the leading and following vehicles can be calculated with traffic and weather data and compared. According to the relationship between clearance distance between the two consecutive vehicles...
With the development of technology and quality management, quality management has become a comprehensive subject, and the field it involved is more complicated. Environment has be considered in quality management. And carbon footprint has become the hot topic in the quality management. This paper aimed to study key process areas of quality management system on the view of carbon footprint and cloud...
Normalization is a basic principle when designing the relational database, which guarantees the revision of data structure and the quality of reorganization, but when referring to data mining system, anti-normalization is needed for data warehouse design. This paper discusses the necessity of anti-normalization and the typical design methods. At the same time, it explains how to realize the data warehouse...
We have designed and fabricated a coplanar waveguide ferromagnetic parametric amplifier based on ferromagnetic alloy cobalt-iron (CoFe) thin film. The ferromagnetic parametric amplifier has the gain of 4 dB at 1.15 GHz. To our knowledge, it is the first coplanar waveguide ferromagnetic parametric amplifier operating at radio frequency reported to date, and we haven't found an item from Google search...
