Arvin: Greybox Fuzzing Using Approximate Dynamic CFG Analysis

Mathias Josef Payer

Fuzzing has emerged as the most broadly used testing technique to discover bugs. Effective fuzzers rely on coverage to prioritize inputs that exercise new program areas. Edge-based code coverage of the Program Under Test (PUT) is the most commonly used cov ...

Design optimization of the Upper Steering Mirror Assembly (USMA) for ITER ECHUL in view of disruptive events

Timothy Goodman, René Chavan, Anastasia Xydou, Matteo Vagnoni

Four Electron Cyclotron Heating Upper Launchers (ECHUL) will be used at ITER to counteract magneto-hydrodynamic plasma instabilities by targeting them with up to 20 MW of mm-wave power at 170 GHz. The millimeter waves are guided through a set of fixed mirr ...

Acoustic emission and ultrasonic testing for fatigue damage detection in a RC bridge deck slab

Eugen Brühwiler, Imane Bayane

There is a significant need to examine precisely the conditions of concrete road bridges because of the increasing traffic and axle loads and the fact that most existing bridges were not designed with respect to fatigue. In-situ investigations are challeng ...

High resolution eddy current inspection and eddy current testing for additive manufacturing

David Florian Hippert

Non-destructive testing (NDT) is one of the key method developed for the safety mechanism of many industrial fields, e.g. aerospace, oil and gas and power industries. Among the NDT techniques, eddy current testing belongs to the well-established ones and h ...

Characterization of Surface Cracks Through The Local Magnetic Field Induced by Eddy Currents

Hannes Bleuler, Marco Picasso, Pavel Kejik, Roland Moser, David Florian Hippert

It is important to reliably characterize cracks in metallic mechanical parts in order to assess the serenity of damage due to fatigue. The most important parameter for this is the crack depth. This is notoriously difficult with standard Eddy current techni ...

The High-Resolution Magnetic Camera: A Novel Sensor for Eddy Current Testing

Hannes Bleuler, Marco Picasso, Pavel Kejik, Roland Moser, David Florian Hippert

Eddy current techniques are often used to detect and, in some advanced applications, to characterize fatigue surface-breaking cracks appearing in mechanical parts. One of the major difficulties in this approach is to reliably separate the crack contributio ...

An Integrated Probe for Electromagnetic NDT Inspection

Pavel Kejik

Electromagnetic techniques present definite advantages for Non Destructive Testing such as no need for surface couplant, potential for miniaturization, and fast scanning rates. They suffer, however, from a lack of reliability when crack sizing capabilities ...

Qualification tests for ITER TF conductors in SULTAN

Pierluigi Bruzzone, Rainer Wesche, Boris Stepanov

From February 2007 to May 2008, 18 short length conductor sections have been tested in SULTAN for design verification and manufacturer qualification of the ITER Toroidal Field (TF) conductor. The test program is focussed on the current sharing temperature, ...
