OBJECTIVE The aim of this study was to test the hypothesis that the effects of filling technique, cavity configuration and use of a low-viscosity composite liner influence resin bond strength to the dentin of class II cavities gingival floor; and analyze the failure modes of fractured specimens. METHODS Standardized class II cavities were prepared in the proximal surfaces of freshly extracted...

background and aims. effect of surface treatments on repair bond strength of aged composite resins might be different due to their dissimilar fillers. the aim was to evaluate the effect of different surface treatments on repair micro-shear bond strength (µsbs) of silica- (spectrum tph) and zirconia-filled (filtek z250) composite resins. materials and methods. twenty-seven composite resin blocks...

This paper presents an intelligent control strategy to overcome nonlinear and time-varying characteristics of a diaphragm-type pneumatic vibration isolator (PVI) system. By combining an adaptive rule with fuzzy and sliding-mode control, the method has online learning ability when it faces the system's nonlinear and time-varying behaviors during an active vibration control process. Since the pro...

Modern decision support systems need to be connected online equipment so that the large amount of data available can used guide decisions shop floor operators, making full use potential industrial manufacturing systems. This paper investigates a novel optimization and analytic method implement such system, based on heuristic generation using genetic programming simulation-based running digital ...

A method to segment a floor and an obstacle region from images, is a fundamental function for robots in real-world. This paper describes a floor detection method by integrating binocular stereo vision and whole body information, for walking direction control of a humanoid robot. We developed the humanoid robot navigation system using vision based local floor map. The developed system consists o...

BACKGROUND Laparoscopic ventral mesh rectopexy using a composite mesh is a technique gaining more recognition for management of pelvic floor disorders such as full thickness rectal prolapse, obstructive defecation symptoms and vaginal vault prolapse. A recent Cochrane review concluded that laparoscopic rectopexy results in fewer postoperative complications and an earlier discharge1 over open me...
