Roller-Compacted Concrete (RCC), which is a kind of dry consistency concrete with zero slump, has two various main applications, pavement and dams.But, owing to the benefits such as cost efficiency, low hydration heat, durability, and high speed of execution, RCC is particularly preferred in the construction of airstrips, ROLLER RELIEF MASSAGER mil
A Range Ambiguity Suppression Processing Method for Spaceborne SAR with Up and Down Chirp Modulation
Range ambiguity is one of the factors which affect the SAR image quality.Alternately transmitting up and down chirp modulation pulses is one of the methods used to suppress the range ROLLER RELIEF MASSAGER ambiguity.However, the defocusing range ambiguous signal can still hold the stronger backscattering intensity than the mainlobe imaging area in
POF: Probability-Driven Opportunistic Forwarding for Bike-Sharing System
The opportunistic networks and the bike-sharing systems have been attracting much research attention in these years.In this paper, the cycling trips and the buffers of bike stations are utilized to relay the large volume of data.The Markov chain is exploited to formulate and Cleaners estimate the delivery ratio with the mathematical lattice model.T
Analysis of Slipper Overturning and Collision Behavior of the Axial Piston Pump Based on Rigid-Flexible Coupling
In the working process of the axial piston pump, the composite multi-degree motion of the slipper and its coupling, as well as the complex working conditions, cause the slipper to overturn and collide irregularly with its coupling.The overturning of the Classic Equine Cinch and Latigo Protector slipper leads to partial abrasion of the slipper, and
Torsional Vibration Suppression During Mode Transition Process in a Parallel Hybrid Electric Vehicle Based on Multiple Model Predictive Control
The mode transition process from electric mode to hybrid electric mode may cause a deterioration in the comfort of the parallel hybrid electric vehicle.To tackle this issue, a coordinated control strategy considering torsional oscillation of mode transition are developed in this study.First, the powertrain topology and powertrain dynamic are introd
