This work presents a study of chromatic and luminance stimuli in low-, medium-, and high-frequency stimulation to evoke steady-state visual evoked potential (SSVEP) in the behind-the-ears area. Twelve healthy subjects participated in this study. The electroencephalogram (EEG) was measured on occipital (Oz) and left and right temporal (TP9 and TP10) areas. The SSVEP was evaluated in terms of amp...

Earthquake Early Warning Systems (EEWS), based on real-time prediction of ground motion or structural response measures, may play a role in reducing vulnerability and/or exposition of buildings and lifelines. In fact, recently seismologists developed efficient methods for rapid estimation of event features by means of limited information of the P-waves. Then, when an event is occurring, probabi...

Abstract Aim Consenting patients appropriately and well-written operative notes are essential for patient care. Anecdotal evidence highlighted that both of these areas could be improved in a urology directorate working across four hospitals. This QIP aimed to assess if consent forms included the risks stated by British Association Urological Surgeons (BAUS) leaflet each operation compliance wit...

An image processing algorithm for detecting individual weeds was developed and evaluated. Weed detection processes included were normalized excessive green conversion, statistical threshold value estimation, adaptive image segmentation, median filter, morphological feature calculation and Artificial Neural Network (ANN). The developed algorithm was validated for its ability to identify and dete...

The electric transmission failure induced by the electrostatic migration and deposition of friction-pair-produced abrasive dusts in Solar Array Drive Assembly (SADA) is studied for first time integrating experiments Finite Element Method (FEM) simulation. Particle morphology composition are characterized SEM X-ray EDS, respectively. size, distribution average charge PSDA as well home-made parti...
