Writer Identification Using Inexpensive Signal Processing Techniques

, 2009
We propose to use novel and classical audio and text signal-processing and otherwise techniques for "inexpensive" fast writer identification tasks of scanned hand-written documents "visually".

Application of a metatranscriptomics technology, CSI-Dx, for the detection of pathogens associated with prosthetic joint infections

Scientific Reports
Preoperative identification of causal organism(s) is crucial for effective prosthetic joint infection treatment. Herein, we explore the clinical application of a novel metatranscriptomic (MT) workflow, CSI-Dx, to detect pathogens associated with ...

Coherent noise source identification in multi channel analysis [PDF]

, 2014
The evaluation of coherent noise can provide useful information in the study of detectors. The identification of coherent noise sources is also relevant for uncertainty calculations in analyse where several channels are combined.

Capabilities of inverse scheme for acoustic source localization at low frequencies

Acta Acustica, 2021
We present the capabilities of a recently developed inverse scheme for source localization at low frequencies within an arbitrary acoustic environment. The inverse scheme is based on minimizing a Tikhonov functional matching measured microphone signals ...

Inverse Source Identification based on Acoustic Particle Velocity Measurements [PDF]

, 2002
A general applicable acoustic source identification method is the inverse frequency response function technique (IFRF). In the standard IFRF method acoustic pressures measured on a grid in the nearfield of the acoustic source are used.

Real time plasma equilibrium reconstruction in a Tokamak [PDF]

, 2008
The problem of equilibrium of a plasma in a Tokamak is a free boundary problemdescribed by the Grad-Shafranov equation in axisymmetric configurations. The right hand side of this equation is a non linear source, which represents the toroidal component of
