Aiming at the problem of large tracking error desired curve for automatic train operation (ATO) control strategy, an ATO algorithm based on RBF neural network adaptive terminal sliding mode fault-tolerant (ATSM-FTC-RBFNN) is proposed to realize accurate curve. On one hand, considering state delay trains in operation, a nonlinear dynamic model established mechanism motion mechanics. Then, princi...

In this study, a new medical bone screw was designed and manufactured by Ti6Al4VELI GR23 material and tested in accordance with the ATSM F 543-02 test procedure experimentally. This test is used to measure the axial tensile force required to fail or remove a bone screw from a defined material. Concurrently, 3-D Finite Element Analysis (FEA) models of these medical bone screws were developed to ...

Affine term structure models are widely used for studying the relationship between yields on assets of different maturities. However, it can be a helpful tool construction fixed-income portfolios. The monitoring these bond portfolios is great importance investor. purpose this work twofold. Firstly, we construct and optimize using Markowitz’s portfolio approach to multifactor Gaussian affine mod...

Tumour hypoxia represents a significant challenge to the curability of human tumours leading to treatment resistance and enhanced tumour progression. Tumour hypoxia can be detected by non-invasive and invasive techniques but the inter-relationships between these remains largely undefined. [18F]Fluoromisonidazole-3-fluoro-1-(2'-nitro-1'-imidazolyl)-2-propanol ([18F]MISO) and Cu-diacetyl-bis(N4-m...
