The occurrence of perceived reversed motion while observers view a periodic, continuously moving stimulus (the "continuous Wagon Wheel Illusion") has been taken as evidence that some aspects of motion perception rely on discrete sampling of visual information. The spatial extent of this sampling is currently under debate. When two separate motion stimuli are viewed simultaneously, the illusion ...

The effective production of high-quality anthracite has attracted increasing global attention. Based on the coal occurrence in Yongxia Mining Area and mining conditions of a coalface in Xinqiao Coal Mine, we proposed a systematic study on the technical support for the production of high-quality anthracite. Six key steps were explored, including coal falling at the coalface, transport, undergrou...

In this paper, the maximum achievable throughput is analyzed in intra-wagon channel when multiple-input single-output (MISO) and orthogonal frequency division multiplexing (OFDM), MISO-OFDM, techniques are used. This analysis performed from real wideband propagation measurements at 28 37 GHz, two potential bands to deploy future fifth-generation (5G) wireless communications networks. Four diffe...

many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (asf) of such systems. in this paper, the behaviour of integrating the phase change material (pcm) in sdhw systems is modelled and optimized numer...

Zooplankton populations are spatially heterogeneous in nature and inside ship ballast tanks. Sampling methods should take heterogeneity into account, particularly when estimating quantitative variables such as abundance or concentration. It is particularly important to generate unbiased estimates of zooplankton concentration in ballast water when assessing compliance with new international ball...
