Abstract Wear failure of the slipper pair is a limiting factor for lifetime high power density axial piston pumps. Existing studies have revealed lubrication support characteristics oil film through heat-fluid-solid multi-field coupling model pair, but due to lack wear calculation at rupture in model, prediction cumulative damage cannot be realized, which has become technological bottleneck improvement performance and life extension pumps.This paper proposes texture design methodology aimed...

Summary An innovative high‐strength steel framed‐tube structure system with web‐bolted double‐channel shear links (SFTS‐WSL) is introduced herein as an alternative solution to strengthening the seismic performance and earthquake resilience of structures while maintaining recognized advantages conventional (SFTS). In SFTS‐WSL, consist a section connected ends spandrel beams via connections. A 2/3‐scale subassembly was tested under cyclic loading investigate behavior replaceability links. The...

Abstract Nitrogen oxides (NOx) are produced during the high‐temperature combustion process of fossil fuels, which considered as an atmospheric pollutant that can lead to significant environmental issues such acid rain and photochemical smog. Therefore, it is essential minimize concentration NO x in atmosphere order protect ecological environment upon human beings depends. The integrated utilization removal technology results environmentally harmless compounds, N 2 H O, through processes like...

Summary High‐strength steel framed‐tube structures with shear links (HSSFT‐SLs) exhibit better performance under seismic loading than conventional structures. In this study, the optimum lateral force distribution considering higher mode effects in an inelastic state for design of HSSFT‐SLs was investigated to overcome shortcomings existing patterns. A series example expected yield mechanisms were designed, and their finite element (FE) models developed by using OpenSees program. The modeling...

Abstract Furfural residue (FR) is an inevitable by-product of industrial furfural production. If FR not managed properly, it will result in environmental problems. In this study, was used as a novel precursor for activated carbon (AC) production by H3PO4 activation under different conditions. Under optimum conditions, the prepared FRAC had high BET surface area (1,316.7 m2/g) and micro-mesoporous structures. The then adsorption Cr(VI). effect solution pH, contact time, initial Cr(VI)...

According to the fundamental feature of holistic drilling shipborne Command and Control(C2) system, this paper proposed a set appraisal procedure index system assess effectiveness C2 system. The basic principles rules should be followed in assessment process are analyzed, hierarchy structure evaluation is established, criteria computing method each provided, calculation weights analyzed. could used evaluate surface warship, helpful promote training combat warship.

Standing at the perspective of project management, this thesis, from relation between schedule, quality and cost, analyzes how cost was influenced by schedule risk risk, assesses total with artificial neural network BP algorithm, determines most sensitive factors which could provide reference for managers to control risk.

Summary A high‐strength steel framed‐tube structure with shear links fabricated using low‐yield‐point (HSSFTS‐LYPSL) was developed in this study to improve the seismic performance and resilience of conventional structure. When HSSFTS‐LYPSL is subjected strong earthquake excitation, its undergo significant plastic deformation dissipate energy while critical components such as spandrel beams columns maintain their elasticity. Furthermore, replacement damaged facilitated by use bolted end‐plate...

In the traditional coaxial infrared television optical system, central aperture of imaging system will be blocked by which cause obvious loss luminous flux and decrease diffraction limit. Because is in channel, size, configuration, performance, assembly affect each other, increases design difficulty, as well processing maintenance difficulty. this paper, an off-axis composite designed. The systems are decoupled from other without interference. Two tilt lenses added front lens to correct...

Soil water content (SWC) is a vital parameter for understanding crop growth and the soil nutrient cycle. Monitoring SWC without inserting sensors into soil, which can break structure, has previously been significant challenge scientists. In this study, we developed non-inserted portable frequency domain reflection (NIP-FDR) instrument to monitor continuously automatically. The working technique of was based on improved adjustable high-frequency oscillation method originating from principle....
