Design of Three - speed Automatic Speed Changer

The bicycle is constantly being updated in order to meet market needs, the developing trend of bicycle shifting gear has changed from manual shifting fashion into automatic shift fashion. In this paper, a systematic approach is proposed to synthesize the design concept of the three-speed automatic speed changer. In this paper, we accord to the design concepts of planetary gear trains with two d...

Stop-flow lithography in a microfluidic device.

Polymeric particles in custom designed geometries and with tunable chemical anisotropy are expected to enable a variety of new technologies in diverse areas such as photonics, diagnostics and functional materials. We present a simple, high throughput and high resolution microfluidic method to synthesize such polymeric particles. Building off earlier work that we have done on continuous flow lit...

Automatic Construction of Chinese Stop Word List

In modern information retrieval systems, effective indexing can be achieved by removal of stop words. Till now many stop word lists have been developed for English language. However, no standard stop word list has been constructed for Chinese language yet. With the fast development of information retrieval in Chinese language, exploring Chinese stop word lists becomes critical. In this paper, t...

Magnetic Field Alignment in the Beam-Beam Compensation Device

Guiding solenoidal magnetic field of the Tevatron beambeam compensation device has to be carefully aligned with respect to a straight trajectory of the antiproton beam. We present in this paper an optical method which allows to measure the direction of the magnetic field, results of magnetic measurements, and results of the field quality improvement with dipole correctors.
