Modeling gas separation in flat sheet membrane modules: Impact of flow channel size variation

open access: yesCarbon Capture Science & Technology, 2023
Flat sheet membranes offer many advantages over other membrane configurations, (e.g. ease of maintenance and low pressure drops) that make them a strong candidate for post-combustion carbon capture.

An 8×240 Gbps dense wavelength division multiplexing transmitter with lithium tantalate [PDF]

open access: yesNature Communications
Dense wavelength division multiplexing (DWDM) is regarded as a revolutionary solution that significantly enhances transmission capacity. However, DWDM in electro-optic (EO) material platforms faces bottlenecks including limited channel numbers, large ...

Robust estimation in flat fading channels under bounded channel uncertainties [PDF]

open access: yesDigital Signal Processing, 2013
We investigate channel equalization problem for time-varying flat fading channels under bounded channel uncertainties. We analyze three robust methods to estimate an unknown signal transmitted through a time-varying flat fading channel. These methods are based on minimizing certain mean-square error criteria that incorporate the channel uncertainties ...

Expectation Propagation for Flat-Fading Channels

open access: yesIEEE Wireless Communications Letters, 2023
This letter addresses the problem of signal detection in flat-fading channels. In this context, receivers based on the expectation propagation framework appear to be very promising although presenting some critical issues. We develop a new algorithm based on this framework where, unlike previous works, convergence is achieved after a single forward ...

Thermal-hydraulic performance of flat-plate microchannel with fractal tree-like structure and self-affine rough wall

open access: yesEngineering Applications of Computational Fluid Mechanics, 2023
Inspired by the natural bifurcating structures, tree-like microchannels have been applied for microelectronics cooling. In order to understand the thermal-hydraulic performance of a flat-plat tree-like microchannel, successive branching ratios of tree ...

MIMO system capacity based on different numbers of antennas

open access: yesResults in Engineering, 2022
This paper analyzed and compared the ergodic channel capacities of several typical channel systems (SISO, SIMO, MISO, MIMO) in independent identically distributed flat Rayleigh fading channels. The theoretical and simulation results show that the ergodic

Sedimentary facies characteristics and metallogenic model of the lower Cambrian Maidiping formation in the Huangjiaping phosphate deposit, Mabian County, southern Sichuan

open access: yesDizhi lixue xuebao, 2023
The lower Cambrian Maidiping formation in the Mabian area of southern Sichuan is a crucial ore-bearing horizon for Kunyang-style phosphate ores. The sedimentary paleoenvironment controls the distribution of phosphate ore.

Experimental Study of the Bending Performance of Cold-Formed Steel Channel Beams Considering the Corner Hardening Effect

open access: yesBuildings, 2023
Cold-formed steel channel beam components are increasingly used in lightweight steel buildings owing to the high strength–weight ratio. However, the influence of cold working processes, in relation to corner regions, and how this impacts the bending ...
