The rotating blade is a key component of an aero-engine, and its vibration characteristics have an important impact on the performance of the engine and are vital for condition monitoring. This paper reviews the research progress of blade dynamics, including three main aspects: modeling of blades...
Keywords: ARAIM; signal-in-space user range errors; false alert probability; availability 1. Introduction Advanced Receiver Autonomous Integrity Monitoring (ARAIM) can provide global users with integrity monitoring service for vertical guidance [1]. The ARAIM algorithm is affected by several error ...

The gauge is equipped with Tretyakov and Alter Shields [40,41] and placed inside a double-fence intercomparison reference (DFIR) to minimize the effect of wind [41–43]. It also uses a special filter algorithm to prevent incorrect measurement [44]. There are two years of measurements (2017...
Phylogenetic trees were constructed Microorganisms 2022, 10, 1257 3 of 15 according to the neighbor-joining (NJ) and maximum-likelihood (ML) methods using the Kimura two-parameter model [46]. The min-mini heuristic algorithm was applied in the maximum-parsimony (MP) method to compare the ...
1750 3 of 21 influencing factors, although some studies have used the method of adding the sum or product of two influencing factors to the regression model and testing its significance to identify the extent of interaction between two influencing factors, assuming an additive or multiplicative inter...
Furthermore, the physical properties and fluid flow rules of each system are different. Based on the network fracture propagation process and the final form in the tight oil reservoir, a physical model of an SRV fractured horizontal well was built that considered the structure characteristics of ...
Predictive maps were created by interpolation using the Ordinary Kriging algorithm. The main results of this study were that, when transitioning from a rainfed to irrigation CS, SOM content is maintained in Cambisols but decreases in the other RSGs, pHw is maintained and EC increases in Fluvisols...
Unlike a low-voltage electric heater with a heating capacity of about 1 kW, such as that used as an auxiliary heater in a conventional internal combustion engine [10,11], the capacity of the main heating system of an electric vehicle is generally 5 kW or higher. A high-voltage PTC ...
Driving cycle, also known as the vehicle test cycle, is a description of the speed-time curve of the vehicle, reflecting the kinematic characteristics of the vehicle road driving; is an significant, common basic technology in the automotive industry; and is the basis of the vehicle energy ...
