Fluid pressure, an important parameter of fluid flow, affects the control accuracy and stability of fluid transmission. The control devices of fluid pressure are widely applied to the mechanical transmission control, which is the main means to change the fluid pressure and improve control accuracy and stability in the mechanical transmission system. To control the accuracy and stability of the fluid transmission, the pressur Read More

Precision medicine has emerged with the development of science and technology and the rise of big data. This study first defines and presents the advantages of precision medicine and then introduces the development of three technologies: gene sequencing, cellular immunotherapy, and gene editing. The clinical applications of precision medicine in lung cancer, cervical cancer, breast cancer, and prostate cancer are thus analy Read More

Background: One of the critical factors affecting the life of bearings is the bearing temperature during operation, so the temperature is an important parameter to detect the running state of the bearing. The abnormal increase in bearing temperature can reflect problems such as bearing damage, lack of lubricating oil, and installation errors. With the continuous improvement of rotating machinery equipment oper Read More

Background: Superhydrophobic surfaces have unique wettability and have shown broad application prospects in many fields, such as self-cleaning and lubrication drag reduction. However, the superhydrophobic surfaces are severely restricted by their poor mechanical stability in practical application, and the mechanical stability of the superhydrophobic surface is always affected by different preparation methods. Therefor Read More

Background: The single state enumeration method cannot meet the requirement of accuracy and high efficiency in the reliability assessment of complex power systems because of many uncertain factors and the large scale of the power grid. Methods: A new method of generating system reliability assessment based on Self-Organizing Map (SOM) neural network and state enumeration is presented. First, the input paramete Read More

Background: Enabling industrial environment with automation is growing trend due to the recent developments as industry 4.0 centric production. The industrial wireless sensor network environments have a number of constraints, including densely deployed nodes, delay constraint for mechanical operation, and access constraints due to node position within instruments. The related literature have applied existing mode Read More

Background: The study on facemask detection is of great significance because facemask detection is difficult, and the workload is heavy in places with a large number of people during the COVID-19 outbreak. Objective: The study aims to explore new deep learning networks that can accurately detect facemasks and improve the network's ability to extract multi-level features and contextual information. In addition, the proposed Read More

Background: Coronavirus (COVID-19) has appeared first time in Wuhan, China, as an acute respiratory syndrome and spread rapidly. It has been declared a pandemic by the WHO. Thus, there is an urgent need to develop an accurate computer-aided method to assist clinicians in identifying COVID-19-infected patients by computed tomography CT images. The contribution of this paper is that it proposes a pre-processing tech Read More
