Experimental Validation of High Precision Web Handling for a Two-Actuator-Based Roll-to-Roll System [PDF]

open access: yesSensors, 2022
In this paper, experimental validation of high precision web handling for a two-actuator-based roll-to-roll (R2R) system is presented. To achieve this, the tension control loop is utilized to regulate the tension in the unwinder module, and the velocity ...

DotSlash: handling web hotspots at dynamic content web sites [PDF]

open access: yesProceedings IEEE 24th Annual Joint Conference of the IEEE Computer and Communications Societies., 2005
We propose DotSlash, a self-configuring and scalable rescue system, for handling web hotspots at dynamic content Web sites. To support load migration for dynamic content, an origin Web server sets up needed rescue servers drafted from other Web sites on the fly, and those rescue servers retrieve the scripts dynamically from the origin Web server, cache

Dynamic Handling for Cooperating Scientific Web Services [PDF]

open access: yes2011 IEEE Seventh International Conference on eScience, 2011
Many e-Science applications are increasingly relying on orchestrating workflows of static web services. The static nature of these web services means that workflow managment systems have no control over the underlying mechanics of such services. This lack of control manifests itself as a problem as optimization techniques such as data-locality aware ...

Simulation of wavy wrinkling of web caused by roller tilt (Change of the number of wrinkles and causes of the onset of the wrinkling)

open access: yesNihon Kikai Gakkai ronbunshu, 2018
This paper deals with the onset and development of wavy wrinkling of a web caused by a roller tilt using a FEM commercial software. The simulation model mainly used is composed of two rigid rollers and a web (a rectangular sheet) divided by a membrane ...

Exception handling in workflow-driven Web applications [PDF]

open access: yesProceedings of the 14th international conference on World Wide Web - WWW '05, 2005
As the Web becomes a platform for implementing B2B applications, the need arises of Web conceptual models for describing Web oriented workflow applications implementing business processes. In this context, new problems about process correctness arise, due to the loose control of Web applications upon the behavior of their Web clients.

Optimum Winding Tension and Nip-load into Wound Webs for Protecting Wrinkles and Slippage

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
This paper describes the novel optimization method of wind-up tension to prevent wound roll defects, mainly star defect (wrinkling) and telescoping (slippage), based on the optimum design technique.

Theoretical and Experimental Investigation into Generation of Wrinkling and Slip in Plastic-Films under Transportation

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
In the transport processes of plastic-films, wrinkling is sometimes generated due to misalignment of roller. To avoid the wrinkling, it is effective to reduce the web tension. However, under the low web tension, the traction inevitably falls as transport
