Quantifying Signal Quality From Unimodal and Multimodal Sources: Application to EEG With Ocular and Motion Artifacts

Frontiers in Neuroscience, 2021
With prevalence of electrophysiological data collected outside of the laboratory from portable, non-invasive modalities growing at a rapid rate, the quality of these recorded data, if not adequate, could affect the effectiveness of medical devices that ...

A Protocol for Comparing Dry and Wet EEG Electrodes During Sleep

Frontiers in Neuroscience, 2020
BackgroundSleep is commonly assessed by recording the electroencephalogram (EEG) of the sleeping brain. As sleep assessments in a lab environment are cumbersome for both the participant and researcher, it would be highly desirable to record sleep EEG ...

Simulation of a signal quality survey [PDF]

Proceedings of the 29th conference on Winter simulation - WSC '97, 1997
This paper describes a simulator for a large outdoor operation called a signal quality survey. Design and implementation of the simulator follows an object oriented approach with a primary focus of modeling operations cycles. The simulator is implemented in Visual C++/CSIM17. Excel acts as the primary user interface.

Supervised SVM Transfer Learning for Modality-Specific Artefact Detection in ECG

Sensors, 2021
The electrocardiogram (ECG) is an important diagnostic tool for identifying cardiac problems. Nowadays, new ways to record ECG signals outside of the hospital are being investigated. A promising technique is capacitively coupled ECG (ccECG), which allows

Quality Signals in Generated Stories [PDF]

Proceedings of the Seventh Joint Conference on Lexical and Computational Semantics, 2018
We study the problem of measuring the quality of automatically-generated stories. We focus on the setting in which a few sentences of a story are provided and the task is to generate the next sentence (“continuation”) in the story. We seek to identify what makes a story continuation interesting, relevant, and have high overall quality.

Increasing diurnal and seasonal amplitude of atmospheric methane mole fraction in Central Siberia between 2010–2021 [PDF]

Atmospheric Chemistry and Physics
Siberia's vast wetlands, permafrost, and boreal forests are significant, but their sources of methane (CH4) are poorly quantified. Using vertical CH4 profiles and meteorological data from the ZOtino Tall Tower Observatory (ZOTTO; 60°48′ N, 89°21′ E) in ...

Objectively measuring signal detectability, contrast, blur and noise in medical images using channelized joint observers [PDF]

, 2013
To improve imaging systems and image processing techniques, objective image quality assessment is essential. Model observers adopting a task-based quality assessment strategy by estimating signal detectability measures, have shown to be quite successful ...

Waiting for Signalling Quality [PDF]

SSRN Electronic Journal, 2011
When a durable good of uncertain quality is introduced to the market, some consumers strategically delay their buying until the next period, with the hope of learning the unknown quality. I analyze the monopolist's pricing and waiting strategies when consumers have strategic delay incentives. I show when the monopolist offers introductory low prices in
