Obstructive sleep apnea hypopnea syndrome (OSAHS) is a kind of breathing regulator disorder disease in sleep, which is related to many complex factors and not yet fully elucidated the pathological state. This pathological state is not only related to snoring, excessive daytime sleepiness (EDS), also due to hypopnea or apnea caused by repeated episodes of hypoxia and hypercapnia, which can lead to...
Brain-computer interface (BCI) system uses brain activity to control external devices such as computers and electronic devices. It is a novel kind of human computer interaction. BCI system can be regard as pattern recognition system, and the key point is classification of Electroencephalogram (EEG) signals under different mental tasks. Classification algorithms of BCI system include Fisher linear...
This paper is devoted to prove the generalized Φ-accretive mapping A : D(A) ⊆ E → 2E or generalized Lipschitz and generalized α - accretive with some specific conditions, then sequence {xn} generated by the steepest descent approximation method which converges strongly to a solution x* of the equation Ax = 0, furthermore, the global convergence theorem is proved.
This paper mainly covers the development of a FPGA-based fuzzy controller and image processing system for a small-sized humanoid robot. All the computations are operated on an FPGA board including the real-time image processing and the fuzzy logic controller design for PK event in FIRA RoboWorld cup. At first, the specification of the hardware is introduced. The image processing is then employed for...
The hubs could lead to degradation of the system performance and add vulnerability to peer-to-peer (P2P) system. This paper proposes a rank-based controlling mechanism to avoid generating hubs in the P2P networks. In this mechanism, each user has a rank according to its contribution and it can just visit the corresponding rating files with its rank in the system. Users can set and manage the ratings...
Free-riding is a grave threat against the existence and efficient operation of Peer-to-peer (P2P) networks. This paper proposes a rank-based incentive mechanism to restrain the free-riding. In this mechanism, each user has a rank according to its utility value and it can just visit the corresponding rating files with its rank in the system. The utility function in this paper takes the absolute contribution...
