With the development of science and technology, people pay more attention on the using of resource. As wood is a not inexhaustible resource, many researchers want to find advanced methods which can reduce the waste materials and enhance timber utilization rate. This paper studied the intelligent numerical control machine for wood processing. Firstly, the requirements of wood processing machine were...
This article studies a paper cutting platform in a comprehensive approach to folk art, folklore, communication, computer and information science focusing on paper-cut in Hebei China. The main content includes: 1) the data collecting and recording of the scattered Chinese folk paper-cut work in Hebei, 2) the digitization, optimization, compression, classification, icon and pattern extraction, vectorization...
In this paper, aluminum nitride (AlN) Lamb wave resonators (LWR) operating in air from room temperature up to 600??C are demonstrated for the first time. To date, no AlN RF devices have been tested and characterized at extreme temperatures. This paper describes the design, fabrication and characterization of temperature compensated AlN Lamb wave resonators at 600??C. Temperature coefficients of frequency...
The validation of process sequences could use the process expert knowledge of specific MEMS pipeline to reason out whether the user-defined process sequences can be manufactured on this pipeline. The process, its parameters and the order of process sequences have great impact on the result of the MEMS device manufactured, even result in that the user-defined process sequences can't be manufactured...
