In this research, 200 corrosion images of steel and 500 crack rubber bearing are collected manually labeled to build the data set. Then two sets respectively adopted train VGG-Unet models in methods, aiming conduct Damage Segmentation by inputting different size One method is Squashing input squashed from high resolution directly into model while Cropping uses cropped image with 224 × as images. Because proportion damage pixels set different, results produced quite different. For large (such...

Abstract Biomechanical analyses are commonly conducted to investigate how craniofacial form relates function, particularly in relation dietary adaptations. However, the absence of corresponding muscle activation patterns, incomplete data recorded experimentally for different individuals during feeding tasks frequently substituted. This study uses finite element analysis (FEA) examine sensitivity mechanical response a Macaca fascicularis cranium varying patterns predicted via multibody...

This article describes the design of a dual-orthogonal <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\pm$</tex-math> </inline-formula> 45 notation="LaTeX">$^\circ$</tex-math> polarized amplifying reconfigurable intelligent surface (RIS). To make possible use two orthogonal polarizations, an RIS architecture where single-port reflection amplifiers (RAs) are connected to antenna ports is considered....

The aim of this study has been to develop a dynamic model the knee joint after total replacement (TKR) analyse stress distribution in distal femur during daily activities. Using MSC/ADAMS and MSC/MARC software, an implanted developed. This consists components prosthesis as well bones ligaments knee. femur, tibia, fibula, patella have modelled mixed cortico-cancellous bone. part flexible body with springs used simulate positioned at their anatomical insertion points. With gait cycle was...

In this paper fixed- and mobile-bearing implants were simulated using a multibody dynamic model finite element to investigate the contact pressure distribution in ultra high molecular weight polyethylene tibial bearing component. The thickness of varied from 6.8 12.3 mm was modelled as non-linear material. It found that on decreased fixed-bearing implant when increased 8 9.6 mm, but there little further decrease with increase 11.0 mm. implant, no superior surface polyethylene; however,...

Abstract The effect of nanofluids on thermal performance the miniature heat pipe radiator which was assembled by two pipes containing 0.6 vol.% SiO 2 /water and 30 pieces rectangular aluminum fins investigated experimentally theoretically. wall temperatures fin surface were measured. Results showed that utilization as a working fluid in enhanced reducing temperature differences. Compared with Deionized water (DI water), resistance decreased about 23% to 40%. Furthermore, theoretical...

Abstract Background To analyze the curvature characteristics of thetalus trochlea inpeople from Northwest China in different sex and age groups. Methods Computed tomography scanning data talus 61 specimens were collected constructed as a three-dimensional model by MIMICS software, anteromedial(AM), posteromedial(PM), anterolateral(AL), posterolateral(PL) edge, anterior edge medial trochlea, posterior lateral defined according to anatomical landmarks on trochlear surface. The radii for areas...

Abstract Background To analyze the curvature characteristics of talus trochlea in people from northern China different sex and age groups.

The robustness of legged locomotion is crucial for quadrupedal robots in challenging terrains. Recently, Reinforcement Learning (RL) has shown promising results and various methods try to integrate privileged distillation, scene modeling, external sensors improve the generalization policies. However, these are hard handle uncertain scenarios such as abrupt terrain changes or unexpected forces. In this paper, we consider a novel risk-sensitive perspective enhance locomotion. Specifically,...

As more and stations devices are connected to the power IoT, their topologies becoming complex, it is a challenge identify effectively correctly so as grasp status of IoT. Problems existing in research: distributed renewable energy such wind low-voltage distribution station area, topology structure area also complicated, accuracy its identification difficult guarantee. In view current IoT can not be dynamically updated time, poor recognition other problems, this paper we prepose based on...

One new type of laminated ceramic interdigital bandpass filter manufactured by low temperature co-fired (LTCC) technology is presented in this article. The designed constructed conductive patterns, which are printed on various sheets. patterns include three stepped-impedance resonators arranged manner, and series resonance branches for transmission zeros. simulated result component shows broad width plus enhanced bandstop rejection.

This paper describes that according to the color spectral lightness theory of CIE and character target, frequency spectrum discreted metamerism can serve as study determination metameric object by optical-electrical image processing obtained pseudo copy. Thus, information be extracted determined accurately, so it is beneficial analysis judgment in chemical, crystal biomedical image, etc. condition medium At first, area supposed characteristic, then, value changed digital system input into...
