final step of rail manufacturing is cold rolling straightening process and it hassignificant effects on mechanical properties, straightness, flatness and development of residualstresses. measurement of residual stresses after straightening process is obligated by railmanufacturing standards. in the present investigation, an attempt has been made to evaluateresidual stresses after straightening ...

A frequency response based adaptive control scheme with robust frequency domain specifications for industrial center-driven web winders is presented in this paper. The adaptive control scheme consists of: 1) a self-tuning initialization, 2) an adaptive control, with robust specifications, based on the transfer function estimation from the frequency response, and 3) supervisory monitoring and co...

Web-winding systems, such as tape drives, are often modeled as linear and timeinvariant, but at least two nonlinearities are common in these systems. First, the reel radii and moments of inertia change as web media spools from one reel to another. Second, friction can draw a thin layer of air between the layers of web media wrapped on the take-up reel, making the system’s spring and damping cha...

• Increased quality With sales of 137 million Euros in 2011, Armor is one of the leaders in producing inked ribbon used in thermal transfer printing for product identification and other applications. Ribbon is produced by applying ink to polyethylene terephthalate (PET) film in a web coating process in which the speed, tension and position of the web and other variables must be closely controll...

This paper analyses folksonomies, an emergent web 2.0 technology. Folksonomies are found to be primarily a social dynamic phenomenon, and several key tensions are hypothesised that keep the folksonomy community vibrant. Strengths and weaknesses of folksonomies are analyzed w.r.t applicability to browsing and search, and suggestions are given on how to alleviate search problems by bringing in ad...
