Eye-blink artifact removal from single channel EEG with k-means and SSA
In recent years, the usage of portable electroencephalogram (EEG) devices are becoming popular for both clinical and non-clinical applications. In order to provide more comfort to the subject and measure the EEG signals for several hours, these devices ...

On artifact solutions of semi-analytic methods in nonlinear dynamics [PDF]
Nonlinear dynamics is a topic of permanent interest in mechanics since decades. The authors have recently published some results on a very classical topic, the dynamics of a softening Duffing oscillator under harmonic excitation focusing especially on ...

Automatic Text-Independent Artifact Detection, Localization, and Classification in the Synthetic Speech [PDF]
The paper describes experiments with statistical approaches to automatic detection, localization, and classification of the basic types of artifacts in the synthetic speech produced by the Czech text-to-speech system using the unit selection method.

Making Digital Artifacts on the Web Verifiable and Reliable [PDF]
The current Web has no general mechanisms to make digital artifacts --- such as datasets, code, texts, and images --- verifiable and permanent. For digital artifacts that are supposed to be immutable, there is moreover no commonly accepted method to ...

The error between appropriately smooth functions and their radial basis function interpolants, as the interpolation points fill out a bounded domain in R^d, is a well studied artifact. In all of these cases, the analysis takes place in a natural function

Robust artifactual independent component classification for BCI practitioners [PDF]
Objective. EEG artifacts of non-neural origin can be separated from neural signals by independent component analysis (ICA). It is unclear (1) how robustly recently proposed artifact classifiers transfer to novel users, novel paradigms or changed ...

Ambulatory Electrocardiographic Monitoring between Artifacts and Misinterpretation, Management Errors of Commission and Errors of Omission [PDF]
BackgroundThe aim of the study is to contrast the role of conventional ambulatory electrocardiographic monitoring (AEM) artifacts with a less emphasized problem with potentially more serious implications, that is, the failure to recognize, and therefore misinterpret, a genuine arrhythmia episode in the AEM recording.MethodsThe study material included ...

Errors in particle tracking velocimetry with high-speed cameras
Velocity errors in particle tracking velocimetry (PTV) are studied. When using high-speed video cameras, the velocity error may increase at a high camera frame rate. This increase in velocity error is due to particle-position uncertainty, which is one of

Systems and methods for physiological signal enhancement and biometric extraction using non-invasive optical sensors [PDF]
A system and method for signal processing to remove unwanted noise components including: (i) wavelength-independent motion artifacts such as tissue, bone and skin effects, and (ii) wavelength-dependent motion artifact/noise components such as venous ...
