ABSTRACT The long‐term thermal oxidative aging behavior of uncompressed and compressed hydrogenated nitrile rubber seals was studied in terms the weight loss, chemical structure, crosslinking density, compression set, fracture morphology, mechanical properties. It found that loss more than due to restricted mobility additives molecular chains under compression. ATR–FTIR results showed hydroxyl groups carbonyl both were formed states, whereas only generation amide observed state....
Existing methods are unable to achieve high detection rates and low false alarm of satellite-based Automatic Dependent Surveillance-Broadcast (ADS-B) signal preambles at extremely signal-to-noise ratios (SNRs) using limited on-star resources. In this paper, a dual-hierarchy synchronization method is proposed, including first-level coarse second-level fine synchronization. The process involves three steps: (1) unknown signals, (2) soft decision, (3) adaptive interval output. first step...
Abstract In order to analyze the rules of thermal-oxidative aging on mechanics Aero-NBR, a hot air accelerated test platform is designed and used research influence Aero-NBR’s mechanical property. The experimental results show that tensile strength Aero-NBR increases with increasing time under certain temperature, elongation at failure first then decreases; effect pressure load, compression stress relaxation factor decreases time: higher faster relaxes. Furthermore, permanent deformation...
Nitrile–butadiene rubbers (NBRs) with different acrylonitrile (AN) contents were used to toughen acrylonitrile–styrene–acrylic terpolymer/styrene–acrylonitrile copolymer (ASA/SAN) blends. The properties of the ASA/SAN/NBR ternary blends investigated via dynamic mechanical analysis, heat distortion temperature, Fourier transform infrared spectroscopy and scanning electron microscopy (SEM). effects AN content in NBR on physical properties, resistance morphology studied. Heat temperature...
The pouch cell is becoming a mainstream among variety of power batteries, because its higher energy density and lower weight. Due to the probability gas production in cell, increasing internal pressure will cause strength degradation sealing area. This process significantly decides safety remaining useful life (USL) cell. paper evaluates adhesive area through accelerated test (ADT) cohesive zone model (CZM), provides method predicting life. In experiments, load-displacement relation was...
This paper analyzes the one-leader-multi-followers unmanned aerial vehicles (UAV) security game with misperception. In leader-follower UAV game, solution concept under misperceptions can be defined as Misperception Strong Stackelberg Equilibrium (MSSE). However, by observing other strategies, players may realize misperception, which makes not trust their current cognition any longer. Therefore, this proposes a model that leader drone is aware of observed differences but all follower drones...
Wireless monitoring systems are increasingly being used in structural health for its benefits of good economy and ease maintenance. However, the energy limited wireless sensor nodes is a major problem systems. In this paper, low-power routing protocol proposed bridge system, has effect on extending network lifetime. Simulation results show that balances consumption, extends lifetime by 30% or more compared with Leach GAF.
