BCI is one of the most intriguing technologies among other HCI systems, mostly because of its capability of recording brain activities. Spelling BCIs, which help paralyzed people to maintain communication, are one of the striking topics in the field of BCI. In this scientific a spelling BCI system with high transfer rate and accuracy that uses SSVEP signals is proposed.In addition, we suggested...

Some complex systems experience multiple dependent competing failure processes, and many traditional approaches to reliability are inadequate or inappropriate because there are two or more dependent/correlated failure processes and multiple components subject to failure. A typical design example representative of these systems is Micro-ElectroMechanical Systems. The dependency among the failure...
