Wireless sensor network (WSN) of active sensors suffers from serious inter-sensor interference (ISI) and imposes new design and implementation challenges. In this paper, based on the ultrasonic sensor network, two time-division based distributed sensor scheduling schemes are proposed to deal with ISI by scheduling sensors periodically and adaptively(More)
OBJECTIVE Diabetes mellitus may impair bone healing after dental implant placement. The objective of this study was to evaluate the effects of the local delivery of basic fibroblast growth factor (bFGF) from poly(lactide-co-glycolide) (PLGA) microspheres on osseointegration around titanium implants in diabetic rats. STUDY DESIGN The bFGF-PLGA microspheres(More)
In order to understand the mechanisms of poor osseointegration following dental implants in type 2 diabetics, it is important to study the biological properties of alveolar bone osteoblasts isolated from these patients. We collected alveolar bone chips under aseptic conditions and cultured them in vitro using the tissue explants adherent method. The(More)
Nonlinear coupling disturbance is an important factor to the precision of three-axis swing turntable. The paper studied platform model and anti-disturbance compensation control algorithm based on robust control idea. A three-axis turntable mathematical model is proposed using theory of DC motor and coupling torque equation. The robust controller is designed(More)
