Substantial damage may occur when a rotary actuator fails during operation. Therefore, effective fault diagnosis of a rotary actuator is crucial to ensuring the safety of the device. However, only a few studies on fault detection, fault isolation, and performance assessment have focused on rotary actuators. In this study, fault detection and fault isolation processes were implemented by designi...

This in vivo, prospective, randomized, single-blinded study histologically compared biofilm/necrotic debridement efficiency of a hand/rotary technique versus a hand/rotary/1 min ultrasound technique in the mesial roots of necrotic, human mandibular molars. The hand/rotary group consisted of 20 mesial roots. The hand/rotary/ultrasound group consisted of 20 mesial roots prepared with the same han...

This paper presents preliminary findings from a research project that examines the interaction between informal risk sharing, index insurance and risk-taking. We have randomized rainfall insurance contracts offered to cultivating and landless households in a set of Indian villages where pre-existing census data on caste networks allows us to characterize the nature and extent of informal risk s...

statement of problem: microorganisms are essential for the development of periradicular diseases and are one of the major causative factors associated with endodontic treatment failures. different instruments and preparation techniques have been developed in endodontics to eliminate or reduce intracanal bacteria. purpose: the aim of this study was to compare the amount of remaining e. faecalis ...

statement of problem: various factors are involved in causing inflammation following root canal treatment. controlling these factors may relieve the related pain. one of these factors is extrusion of debris beyond the apex. although debris extrusion happens in all instrumentation techniques, researchers have declared that in coronal flaring technique, there is minimum debris extrusion. purpose:...

F1-ATPase (F1) is a reversible ATP-driven rotary motor protein. When its rotary shaft is reversely rotated, F1 produces ATP against the chemical potential of ATP hydrolysis, suggesting that F1 modulates the rate constants and equilibriums of catalytic reaction steps depending on the rotary angle of the shaft. Although the chemomechanical coupling scheme of F1 has been determined, it is unclear ...

This paper describes a mathematical model for a novel rotary pneumatic rotary actuator with potential applications in revolute direct robotic mechanisms. The analytical model describes the behaviour of the rotary pneumatic actuator and simulated results using this model are generated. Potential applications of this model are discussed in the context of soft model based controllers used in prost...
