High-rate roll-to-roll (R2R) tracker systems are utilized for large volume flexible electronic device manufacturing, and the current alignment mechanism between layers is mainly achieved by relying on passive techniques. In this paper, we present a machine vision based alignment strategy that is used to achieve precise registration for stacking multilayers. Based on this strategy, we demonstrat...

This paper concerns the tension control of roll-to-roll systems. In such systems, each driven roller speed is controlled separatly. The impact of the master roller position on tension control performances is studied using optimized web tension control synthesis. The tension disturbance rejection property and the system robustness regarding web elasticity variations are analysed for each configu...

We propose a new type of re-writable bitmap image display component using the MEMS (Micro Electro Mechanical Systems) -controlled light scattering. The device is made of a light-guided transparent substrate (glass) and a thin sheet of semi-transparent plastic film (PDMS; Poly Di Methyl Siloxane) with magnetic nickel and light– diffusing glass powders formed in an electrostatic parallel-plate ac...

In an effort to translate PRINT nanoparticle fabrication from batch processes to continuous manufacturing, Liquidia Technologies has harnessed the scale of roll-to-roll processing with the precision of microlithography to enable GMP production of gram to kilogram quantities of nanoparticle based therapeutic formulations. The in-house capabilities now enable fast turnover from single wafer maste...

Roll over transition metals-triarylamines are redox-catalysts, enabling olefin difunctionalization and C–H functionalization reactions by activating benzoyl peroxide.

The paper applies a Bayesian Markov Chain Monte Carlo estimation methodology to scale roll call votes in the 35 and 38 Canadian Parliaments over a multidimensional policy space. The results clearly demonstrate that policy debates are two-dimensional in Canada. The first dimension represents the classical division between the governing and the opposition parties that has been found in similar Pa...

T ROLL is a language to specify information systems with dynamic behavior. Here, we elaborate on the speciication of object aggregation in T ROLL. We distinguish between two kinds of aggregation, static and dynamic aggregation. Static aggregation means that the composition of objects is described using predicates over constant properties. Dynamic aggregation means that we may alter the composit...

We report a possible occurrence of horizontal roll vortices over the Adriatic Sea during the bora wind. The National Center for Atmospheric Research Electra aircraft measured the turbulence structure above the Adriatic on 07 November 1999 during the Mesoscale Alpine Program. The data indicate that horizontal roll vortices are generated by the strong cold-air outbreak associated with bora. The r...

In a persistent object store, the acts of modifying data and reading modified data result in the creation of dependencies between the modifying process and the data. Dependencies may be represented using sets, and over time these may grow to encompass many objects and processes. Checkpoint and roll-back operations must propagate to all elements in such a set. This paper presents a new notation ...
