introduction: brain computer interface (bci) systems based on movement imagination (mi) are widely used in recent decades. separate feature extraction methods are employed in the mi data sets and classified in virtual reality (vr) environments for real-time applications. methods: this study applied wide variety of features on the recorded data using linear discriminant analysis (lda) classifier...

introduction pressure ulcers are tissue damages resulting from blood flow restriction, which occurs when the tissue is exposed to high pressure for a long period of time. these painful sores are common in patients and elderly, who spend extended periods of time in bed or wheelchair. in this study, a continuous pressure and temperature monitoring system was developed for pressure ulcer preventio...

in this paper, we present a fractional mathematical model of a one-dimensional phase phase change problem (stefan problem) with latent heat a power function of position. this model includes space-time fractional derivatives in caputo sense and time dependent surface heat flux. an approximate solution of this model is obtained by optimal homotopy asymptotic method (oham) to find an approximate s...

brain-computer interfaces (bci) record brain signals, analyze and translate them into control commands which are relayed to output devices that carry out desired actions. these systems do not use normal neuromuscular output pathways. actually, the principal goal of bci systems is to provide better life style for physically-challenged people which are suffered from cerebral palsy, amyotrophic la...

conclusions increasing the cu nanoparticles in bioactive glass samples leads to the release of cu2+, which has a positive effect on the antibacterial mechanism, as well as decreasing the cultured staphylococcus colonies found on the bioglasses. therefore, it seems that the nanocomposite/bioglass of cuo is a promising option for aerobic bacterial inhibitor systems in common bone implant infectio...

an interface part is used between clutch pedal and clutch cable in peugeot, samand, rd and peugeot pars. this part is consisted of two pieces. the main body is made of polyamide 6.6 and the second part is made of ck45.due to the fact that the two pieces are made of different assembling geometry with respect to each other, therefore, has caused performance problems which may result in clutch cab...

security term in mobile ad hoc networks has several aspects because of the special specification of these networks. in this paper a distributed architecture was proposed in which each node performed intrusion detection based on its own and its neighbors’ data. fuzzy-neural interface was used that is the composition of learning ability of neural network and fuzzy ratiocination of fuzzy system as...

purpose: to report a case of candida glabrata endophthalmitis after deep anterior lamellar keratoplasty methods: interventional case report results: a young male patient presented with asymptomatic white to cream-colored interface deposits two months after deep anterior lamellar keratoplasty. after a while, severe anterior chamber reaction together with decreased visual acuity developed. becaus...
