improvements in the properties of ordinary sidewall compound (nr/br) with the addition of epdm by reactive processing method were evaluated. the results show that ozone resistance of these sidewalls was improved with increased addition of epdm. also the tensile strength and elongation-at-break were increased in comparison with nrbrepdm compounds that were made by non-reactive processing. sem ph...

Undesired wall thickness distribution and flanging cracking easily occur in reverse drawing–flanging combined processes of steel spokes when improper process parameters are used. Thus, based on GRA (grey relational analysis) and FEM (finite element method), a GRA model for a reverse drawing–flanging combined process for high strength steel B550CL spoke was established and validated. The results...

Database cracking has been an area of active research in recent years. The core idea of database cracking is to create indexes adaptively and incrementally as a side-product of query processing. Several works have proposed different cracking techniques for different aspects including updates, tuple-reconstruction, convergence, concurrency-control, and robustness. However, there is a lack of any...

The Yule–Nielsen modified spectral Neugebauer model YNSN) enhanced for accounting for ink spreading in the different nk superposition conditions requires a spectrophotometer to meaure the reflectances of halftone calibration patches in order to comute the ink spreading curves mapping nominal ink surface coverge to effective ink surface coverage.

Isothiazolinones are used as biocides in a wide variety of products, such as cosmetics, detergents, and industrial products. In the 1980s, a formulation with methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI) was responsible for an allergic contact dermatitis ‘epidemic’. To control this phenomenon, a maximum allowed dose was set. However in 2005, MI alone was introduced in cosmeti...

The existing lithium ion battery model in Multiphysics (MP) software (COMSOL Inc., Palo Alto, CA) is extended to include the thermal effects. The thermal behavior of a lithium ion battery is studied during the galvanostatic discharge process with and without a pulse. ccepted 8 March 2011 vailable online 15 March 2011 eywords: ithium ion battery hermal model © 2011 Elsevier B.V.

Mark Goresky t Andrew Klappex a A b s t r a c t A new class of feedback register, based on ramified extensions of the 2-adic numbers, is described. An algebraic framework for the analysis of these re~ters and the sequences they output is given. TilLs framework parallels that of linear feedback shift resistere. As one consequence of this, a method for cracking summation ciphers is given. These r...
