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...

We present GUEB a static tool detecting Use after Free vulnerabilities on disassembled code. This tool has been evaluated on a real vulnerability in ProFTPD (CVE-2011-4130).

The Attachment Insecurity Screening Inventory (AISI) 2-5 years is a parent-report questionnaire for assessing attachment insecurity in preschoolers. Validity and reliability of the AISI 2-5 years were examined in a general sample (n = 429) and in a clinical sample (n = 71). Confirmatory factor analysis (CFA) confirmed a three-factor model of avoidant, ambivalent/resistant and disorganized attac...

In this paper, experimental results of a deep drawing process to produce a cylinder of high strength steel with a spherical head were compared with it’s simulation results and three proposal design types. Meanwhile, the amount of limiting draw ratio in some stages was determined. Accuracy and precision of the results of a finite element software to predicting the multi stage deep drawing proces...

In this paper we study the corrosion of AISI 304 austenitic stainless steel PEMFC bipolar plates in aqueous and room-temperature ionic-liquid electrolytes. The anodic potential thresholds and dynamics have been investigated by electrochemical (potentiodynamic and potentiostatic) and in situ spectroelectrochemical methods (visible electroreflectance and VIS-UV spectroellipsometry). We measured t...

Sol-Gel coatings are a good choice for protection and bioactivation of metals used as dentistry and standard surgical implant materials. These films should both prevent degradation of the substrates by wear or corrosion, and bioactivate the material for inducing the formation of a hydroxyapatite (HA) rich layer onto the material surface, thereby permitting a natural bonding to living tissues. T...

The first unidentified TeV source in Cygnus is confirmed by follow-up observations carried out in 2002 with the HEGRA stereoscopic system of Čerenkov Telescopes. Using all ∼279 hrs of data, this new source TeV J2032+4130, is steady over the four years of data taking, is extended with radius 6.2′, and has a hard spectrum with photon index −1.9. Its location places it at the edge of the core of t...
