The uncertainty of emissivity has a major effect on the accuracy pyrometer in billet temperature measurement. In order to eliminate influence emissivity, we place reflector with two apertures at front pyrometer. are used measure intrinsic radiation and approximate blackbody billet. is collected by infrared dual-band detectors Then, real-time can be measured no assumptions, so eliminated. additi...

Numerous National Weather Service (NWS) Weather Forecast Office (WFO) local studies (Amburn and Wolf 1997, Billet et al 1997, Blaes et al 1998, Hart and Frantz 1998, Lenning et al 1998, Roeseler and Wood 1997, Troutman and Rose 1997, Turner and Gonsowski 1997) and national studies (Edwards and Thompson 1998, Witt et al 1998, Witt 2002) looked at the relationship between various conventional rad...

The goal of white-box cryptography is to design implementations of common cryptographic algorithm (e.g. AES) that remain secure against an attacker with full control of the implementation and execution environment. This concept was put forward a decade ago by Chow et al. (SAC 2002) who proposed the first white-box implementation of AES. Since then, several works have been dedicated to the desig...

A typical extrusion of low and medium strength aluminium alloys solid shapes is performed with flat pocket dies. The pocket allows realising the extrusion as “billet-to-billet” process, and also facilitates filling-up die channel deadlocks and thin-walled elements of profile [1]. In addition it serves as an instrument for shape geometry control. The scientific literature contains a variety of r...

Abstract This paper mainly focuses on the problem of coarse grain bottom surface red copper horizontal continuous casting billet, and tries to thicken end crystallizer by combining numerical simulation industrial experiment, indirectly improves cooling strength billet solve coarseness. The results show that optimum diameter lower inlet sleeve was 14.2 mm, when increased from 11 mm intensity par...
