A comparative study of impervious surface extraction using Sentinel-2 imagery

European Journal of Remote Sensing, 2020
The accuracy and efficiency of impervious surface extraction using different algorithms vary greatly, and algorithm applicability depends on the study area.

The wadsworth BCI research and development program: at home with BCI

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2006
The ultimate goal of brain-computer interface (BCI) technology is to provide communication and control capacities to people with severe motor disabilities. BCI research at the Wadsworth Center focuses primarily on noninvasive, electroencephalography (EEG)-based BCI methods.

On the stimulus duty cycle in steady state visual evoked potential [PDF]

, 2014
Brain-computer interfaces (BCI) are useful devices that allow direct control of external devices using thoughts, i.e. brain's electrical activity. There are several BCI paradigms, of which steady state visual evoked potential (SSVEP) is the most commonly

Novel dry electrode EEG headbands for home use: Comparing performance and comfort

Current Directions in Biomedical Engineering, 2020
Monitoring brain activity at home using electroencephalography (EEG) is an increasing trend for both medical and non-medical applications. Gel-based electrodes are not suitable due to the gel application requiring extensive preparation and cleaning ...

Full-Field Imaging for Evaluating Mode-II Fracture Toughness in CFRP Laminates

Proceedings
To replicate delaminations at the coupon and substructural scales, simulated defects are often introduced into test specimens; therefore, understanding their behaviour within the laminate is essential.

On the BCI problem

Ars Mathematica Contemporanea
Let $G$ be a group. The BCI problem asks whether two Haar graphs of $G$ are isomorphic if and only if they are isomorphic by an element of an explicit list of isomorphisms. We first generalize this problem in a natural way and give a theoretical way to solve the isomorphism problem for the natural generalization.
