Artifact rejection is a central issue when dealing with electroencephalogram recordings. Although independent component analysis (ICA) separates data in linearly independent components (IC), the classification of these components as artifact or EEG signal still requires visual inspection by experts. In this paper, we achieve automated artifact elimination using linear discriminant analysis (LDA...

Computing today happens across multiple devices, applications, users, organizational units, and in the rest of world outside. Groups communities come together for different reasons operate within contexts that may differ from dominant modes production consumption. With a foundation activity theoretical HCI, we develop concept collective artifact ecologies. This enables us to identify struggles ...

OBJECTIVE To compare the suitability of CO2 laser with steel instruments for margin excision in transoral laser microsurgery. METHODS Prospective randomized blinded study. Patients with glottic cancer undergoing laser resection were randomized to margin excision by either steel instruments or CO2 laser. Margins were analyzed for size, interpretability and degree of artifact by a pathologist w...
