Abstract Background Chinese nurses working with immense stress may have issues burnout during COVID-19 regular prevention and control. There were a few studies investigating status of associated factors among nurses. However, the relationships remained unclear. Objectives To investigate nurses’ Methods 784 completed questionnaires including demographics, Generalized Anxiety Disorder-7, Patient Health Questionnaire-9, Insomnia Severity Index, Impact Event Scale-revised, Perceived Social...
With the depletion of surface resources, mining will develop toward deep in future, objective conditions such as environment be more complex and dangerous than now, requirements for personnel equipment higher higher. The efficient space is inseparable from movable flexible production transportation scrapers. In new era, intelligence leading to development trend scraper (LHD), path tracking control key intelligent it also an urgent problem solved unmanned driving. This paper describes...
The expansion of wheeled mobile robot usage to applications with high loads and speeds requires reliable tracking control that is robust the disturbances emanating from external wheel-ground contact. motion such robots can be accurately described a dynamic model includes both forces complex tire model. However, design full not practical due its complexity nonanalytic form. In this paper, we derive simplified which adequate for treat remaining terms as uncertainty. Then, uncertainty analyzed...
Control allocation considers the problem of controlling instruction distribution for control systems with multiple and redundant actuators. This paper focuses on direct method, making time requirement algorithm analogous compared modified pseudoinverse redistribution methods, linear programming methods solved by simplex sub-gradient optimization method. To reduce off-line computations constructing attainable moment set actuators, a new approach based null space effectiveness matrix is...
In this paper, we present the design of a spherical robot with high shell to drive-unit mass ratio. A drive unit and novel structure for are proposed, reaction wheels used reduce robot's oscillations. Dynamic models established linear motion static state by using Lagrange equation. The stability is studied via simulations in different, such as accelerated state, uniform so on. results demonstrate ability wheel enhance stability.
Intelligent traffic control is an important issue of the modern transportation system. However, in large-scale urban systems, traditional centralized coordination methods suffer bottlenecks both communication and computation. Decentralized hard if there very limited observation to whole network as evidences support joint decisions. In this paper, we proposed a novel decentralized, multiagent based approach for massive lights promote green transportation. Considering that only from adjacent...
The captan residues in apple juice were detected by fluorescence spectrometry, and the content level of was predicted based on a genetic algorithm support vector machines (GA-SVMs). According to concentration juice, experimental samples divided into four levels, including no excess, slight moderate severe excess. A GA used select characteristic wavelength optimize SVM parameters, applied train classification model. 50 points selected from original spectra, which contained 401 points,...

Abstract This paper presents a robust control algorithm for exponentially stable tracking of differentially steered Wheeled Mobile Robot (WMR). The exponential property is guaranteed with kinematic uncertainties, such as wheel slippage and radius errors. has been designed use in WMR which being specifically developed applications highway maintenance construction. For applications, the uncertainties arise due to road surface conditions high loads encountered (both inertial tool forces)....
