Fling-Step Recovering from Near-Source Waveforms Database

Digital Archeology: Recovering Digital Objects from Audio Waveforms

Specimens of early computer systems stop working every day. It is necessary to prepare ourselves for the upcoming situation of having storage media and no working systems to read data from these carriers. With storage media residing in archives for already obsolete systems it is necessary to extract the data from these media before it can be migrated for long term preservation. One storage medi...

Robust and Fast Probabilistic Source Parameter Estimation from Near-Field Displacement Waveforms Using Pattern Recognition

The robust and automated determination of earthquake source parameters on a global and regional scale is important for many applications in seismology. We present a novel probabilistic method to invert a wide variety of (waveform) data for point-source parameters in real time using pattern recognition. Inferences are made in the form of marginal probability density functions for point-source pa...

Recovering management information from source code

At large software-empowered companies, such as banks, a good insight into millions of lines of source code is often missing. Nevertheless, valuable management information often resides in the source code. In this paper we therefore present some source code measures that can be extracted from millions of lines of code in an automated fashion. Source code comments usually contain data such as ver...

Blind Source Separation: Recovering Signals from Mixtures

Critical Earthquake Response of Elastic–Plastic Structures Under Near-Fault Ground Motions (Part 1: Fling-Step Input)

The double impulse input is introduced as a substitute of the fling-step near-fault ground motion and a closed-form solution of the elastic–plastic response of a structure by the “critical double impulse input” is derived. Since only the free-vibration appears under such double impulse input, the energy approach plays an important role in the derivation of the closed-form solution of a complica...
