PURPOSE Photon counting spectral breast CT is feasible in part due to using an adaptive filter. An adaptive filter provides flat x-ray intensity profile and constant x-ray energy spectrum across detector surface, decreases required detector count rate, and eliminates beam hardening artifacts. However, the altered x-ray exposure profiles at the breast and detector surface may influence the distr...

Nowadays control-flow hijacking attacks represents the highest software-based security threat [16]. We want to develop a tool that can measure the exact attack surface reduction w.r.t. the attack, Counterfeit Object-Oriented Programming (COOP) [8]. This attack is particularly hard to defend against since traditional Control Flow Integrity (CFI) [1] approaches and hardware based shadow stacks [1...

The effect of the initial microstructure and intercritical annealing on mechanical properties and work-hardening response of a high-formability low carbon steel were studied. The work-hardening analysis was based on the modified Crussard–Jaoul method. The ferritic-pearlitic sheets showed low strength and high total elongation with the appearance of the yield point phenomenon. The occurrence of ...

In this study, the hardness and wear behaviour of carburized and boronized AISI 8620 steels have been studied. The boronizing treatment increased the hardness of AISI 8620 steels from 395 HV0.1 to a maximal 1610 HV0.1 compared to the carburized steels and also significantly improved its wear behaviour. From obtained results, it can be concluded that boronizing is very effective surface hardenin...

Three newly identified cross-slip mechanisms from atomistic simulations of fcc crystals, namely surface, bulk and intersection cross-slip types, were hierarchically informed into discrete dislocation dynamics simulations. The influence of each cross-slip type on the evolution of the dislocation microstructure in face-centered cubic microcrystals having different crystal sizes and initial disloc...

Laser surface hardening is a promising technology to enhance the properties of surfaces. This was used on 42CrMo press brake die. Its behavior investigated by using scanning electron microscopy and backscattering diffraction. The results indicated that martensite in zone significantly finer than substrate. There were many low-angle grain boundaries zone, kernel average misorientation orientatio...
