The neural mechanisms and long-term effects of perceived stress (PS) self-control (SC) on mental health (MH) are not fully understood. This study seeks to investigate the influence PS SC MH identify their correlates using fMRI. A total 817 college students participated in behavioral assessments, including Perceived Stress Scale (PSS), Self-Control (SCS), Mental Health Continuum Short Form (MHC-SF). Among them, 371 underwent fMRI scans calculate zfALFF whole-brain functional connectivity....
This paper presents two models based on the LuGre model for friction with consideration of thermal effects. In Model I, parameters in are considered as temperature dependent. II, independent; while a temperature-dependent function is added to temperature-independent model. Both experimentally evaluated, which shows that both can effectively incorporate effects but II has better accuracy. Since these developed context motion system, they should be readily incorporated control algorithms...
The piezoelectric stick-slip (PZT-SS) actuator is known to achieve motion with a theoretically unlimited range yet high resolution (several nanometers). In this type of actuator, friction plays an active role in producing meaningful motion. However, source heat which may cause significant temperature rise, affecting the dynamic performance actuator. Our study aimed measure rise and understand whether such could significantly affect displacement study, measurement system was developed using...
Wire rope isolators are mainly used to isolate vibration and protect precise equipment. However, the issue of regulation taking into account nonlinearity their characteristics was poorly understood in modern literature. In this paper, influence structural parameters (diameter ratio lay pitch single strand, bending radius wire rope) on stiffness‐damping Polycal WRI investigated by simplified finite element analysis method. The stiffness damping prediction models including material properties...
It was found experimentally from our previous study that the operation of piezoelectric actuator (PEA) and friction in stick-slip (PE-SSA) can cause significant rise temperature, thereby degrading performance actuator. This paper presents a dynamic model for PE-SSA by taking into account thermal effect. In particular, is developed integrating PEA proposed Adriaens et al. [1] LuGre De Wit [2]; parameters involved models are determined using system identification approach. Experiments carried...
This paper describes an optical system for high temperature strain measurement by using quartz fiber, super long working distance microscope and digital image processing techniques. In this one ends of the fibers are arrayed in a small area on specimen surface other illuminated laser beam. The fiber from spot array. spots tracked CCD camera images processed software. As diameter each is only 100 microns can be tiny area. local strains were determined measuring variety relative between two...
