Roll coating is distinguished by the use of one or more gaps between rotating cylinders to meter and apply a liquid layer to a substrate. Except at low speed, the two-dimensional film splitting flow that occurs in forward roll coating is unstable; a three-dimensional steady flow sets in, resulting in more or less regular stripes in the machine direction. For Newtonian liquids, the stability of ...

In order to further improve the economies of scale which are inherent in ECD’s continuous roil-to-roll amorphous silicon alloy solar cell manufacturing process, we have developed a concept for a serpentine web plasma CVD deposition process to maximize throughput while keeping the size of the deposition chambers small. When this technique is incorporated into a continuous rollto-roll PV manufact...

The optimization of the calendering process represents one key tasks for tuning lithium-ion battery performance. In this study, we present a systematic statistical-based study three main parameters (namely, applied pressure, roll temperature, and line speed) effect on porosity, electrode mechanical properties electronic conductivity. Our work goal is to understand how by changing parameters, ca...

While the effects of legal and institutional arrangements on political participation are well documented, little attention has been given to the potential participatory effects of one of the United States’ most important electoral laws: constitutionally mandated reapportionment. By severing the ties between constituents and their incumbents, we argue, redistricting raises information costs, lea...

Although the roll-streak structure is ubiquitous in both observations and simulations of pretransitional wall-bounded shear flow, this structure is linearly stable if the idealization of laminar flow is made. Lacking an instability, the large transient growth of the roll-streak structure has been invoked to explain its appearance as resulting from chance occurrence in the background turbulence ...

Pecan is one of the spices that become an ingredient in process food and cosmetic industry. The pecan separator machine made to facilitate speed up breaking fruit order increase work efficiency hope can achieve high form good yields. purpose this help community processing maximum its production, also productivity fruit, which improve community's economy. research method applied study experiment...

The use of distributional semantics to represent the meaning of a single word has proven to be very effective, but there still is difficulty representing the meaning of larger constituents, such as a noun phrase. In general, it is unclear how to find a representation of phrases that preserves syntactic distinctions and the relationship between a compound’s constituents. This paper is an attempt...

One of the main tasks to determine technological settings sheet leveling machine (leveler) is identify maximum roll overlap. In well-known works on study metal-roll leveling, overlaps are set basis experimental data, which applicable for sheets from material with 800-MPa yield strength. But materials a higher strength, additional research required. The purpose this work establish criteria affec...
