BPEL can automate orchestrations for cross-organizational Web services; however, it meets a serious challenge from modeling human-intensive business activities. This paper distinguishes human-driven workflow from automated process, and uses state machine to model human-driven workflow, then transforms state machine-style workflow to BPEL process, finally(More)
Considering the necessity of alignment in practical applications of photolithography, distribution of complex amplitude of moiré fringe patterns that are produced in superposition of two gratings is analyzed in the viewpoint of Fourier Optics and the relationship between fringes and properties of these two gratings is concluded by means of an analysis(More)
Traffic has always been the infrastructure of national economic and social development. With the pace of urbanization unprecedented speedup and the increase of vehicle possessions, traffic congestion has become a big problem in modern cities. Regional traffic guidance system provides traffic information for road travelers in pre-trip and in on-trip, and(More)
Three-dimensional printing was used to fabricate various metallic structures by directly integrating a Br-containing vinyl-terminated initiator into the 3D resin followed by surface-initiated atomic-transfer radical polymerization (ATRP) and subsequent electroless plating. Cu- and Ni-coated complex structures, such as microlattices, hollow balls, and even(More)
On account of in situ cross-linked reaction of epoxy SU-8 with poly(4-vinylpyridine) (P4VP) and its strong reactive bonding ability with different pretreated substrates, we developed a simple universal one-step solution-based coating method for fast surface modification of various objects. Through this method, a layer of P4VP molecules with controllable(More)
We demonstrate a tilt-modulated phase imaging method to adjust the gap inconsistency for wafer-mask leveling in proximity lithography. Two gratings with close periods are etched on the mask and used as leveling marks. At the illumination of a monochromatic planar wave, the diffracted image of one grating is projected back onto the other one beside it(More)
We explore the feasibility of a controllable and easy-to-implement moiré-based composite circular-line gratings imaging scheme for optical alignment in proximity lithography. One circular grating and four line gratings located on both the mask alignment mark and wafer alignment mark are used to realize the coarse alignment and fine alignment respectively.(More)
[reaction: see text] The electrophilic cyclization of 2-(1-alkynyl)-2-alken-1-ones in the presence of various alcohols or carbon-based nucleophiles offers an efficient and straightforward route to highly substituted iodofurans under extremely mild reaction conditions. The iodo derivatives are potential synthetic intermediates for amplification of molecular(More)
This paper aims to deal with a four-quadrant gratings alignment method benefiting from phase demodulation for proximity lithography, which combines the advantages of interferometry with image processing. Both the mask alignment mark and the wafer alignment mark consist of four sets of gratings, which bring the convenience and simplification of realization(More)
Designing interfaces that suit human pointing precision in freehand space can improve the smoothness and naturalness of gestural interaction. However, only few studies focus on the proper pointing precision for a comfortable target acquisition to provide suggestions for user-centered interface design for such kind of techniques. This paper presents work on(More)
