Abstract: The dynamic balancing of flexible linkages, which is a challenging topic in the dynamics of mechanisms, is accomplished by active control with redundant drives for the first time in the present ...

Abstract: Wavelet filtering is combined with cyclostationary analysis for detection of gear tooth faults in a gearbox. The parameters of the wavelet filter are optimized by using the proposed entropy ...

Abstract: The processing method of asphalt mixture digital images was investigated on the basis of the gray – level distribution of asphalt concrete images. Some bond areas were found between different aggregates. The watershed ...

Abstract: The values of key parameters, asphalt aggregate ratio, mixing/compacting temperature, striking/compacting times, and fiber content are usually determined according to bulk properties or empirical values when molding asphalt ...

Abstract: For gears and roller bearings, periodic impulses indicate that there are faults in the components. However, it is difficult to detect the impulses at the early stage of fault because they are ...

Abstract: Ambient air samples were collected using Tenax-TA adsorbents at sites of tunnels and urban areas in Tainan, Taiwan, and a remote recreation area and national park in central Taiwan. A gas chromatograph equipped with mass ...

Abstract: The copper(II) complex with alkylphosphonic acid monoalkyl ester (CuAMP) was synthesized, and its structure shown to be laminar on the basis of fast atom bombardment mass spectroscopy (FABMS). ...
