Hot forging is a common manufacturing process for the production of large quantities of engineering components. Residual stresses are developed in forged components as a result of various aspects of the manufacturing process, including subsequent cooling, and heat treatment. Residual stresses can significantly affect the deformation and fatigue failure of materials. Hot forged EN15R steel bars ...

One of the steps during the authorization process of plant protection products (PPP) in the European Union is to evaluate the safety of the operator. For this purpose, information on the probable levels of operator exposure during the proposed uses of the PPP is required. These levels can be estimated by using existing mathematical models or from field study data. However, the existing models h...

Recent occurrences of various Denial of Service attacks which have employed forged source addresses have proven to be a troublesome issue for Internet Service Providers and the Internet community overall. This paper discusses a simple, effective and straightforward methods for using ingress traffic filtering to deny attacks which use forged IP addresses. draft-ferguson-ingress-filtering-01.txt ...

In today’s world every official document need the Hand written signature. To verify that the signature done by the person is accurate and not forged, human brain stores the pattern, data and everything so that they can recognize the pattern or data if again the same thing is shown. But the human mind receives the signal from eye which cannot catch the small variation in the pattern so it become...

Abstract The hydrodynamics of a Top Submerged Lance (TSL) slag bath are investigated here by means Computational Fluid Dynamics (CFD) simulation. object the study is pilot-scale furnace located at TU Bergakademie Freiberg, where air injected beneath with top lance. fluid dynamics system evaluated operating conditions, experimentally measured physical properties and real flow rates. numerical ap...

Digital images can be obtained through a variety of sources including digital cameras and scanners. With rapidly increasing functionality and ease of use of image editing software, determining authenticity and identifying forged regions, if any, is becoming crucial for many applications. This paper presents methods for authenticating and identifying forged regions in images that have been acqui...

Brain imaging techniques such as functional magnetic resonance imaging (fMRI) have forged an impressive link between psychology and neuroscience. Whereas most experiments in cognitive psychology require participants to perform while sitting upright in front of display devices, fMRI obliges participants to perform cognitive tasks while lying supine and motionless inside a narrow bore. In additio...

We present COVERAGE – a novel database containing copymove forged images and their originals with similar but genuine objects. COVERAGE is designed to highlight and address tamper detection ambiguity of popular methods, caused by self-similarity within natural images. In COVERAGE, forged–original pairs are annotated with (i) the duplicated and forged region masks, and (ii) the tampering factor/...
