Pulse Shaping in MIMO COFDM over Rayleigh Fading Channels
, 2009 In order to improve the performance of space-time coded(STC) multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) enhancements were implemented in a MatLab simulation by shaping the OFDM pulses transmitted through ...

Integral Experiments and Magnetic Resonance Imaging of Lab‐Scale Liquid Distributors
Chemie Ingenieur Technik, EarlyView.Four lab‐scale liquid distributors were evaluated based on the homogeneity of the resulting liquid distribution. The best‐performing design reduced maldistribution and wall flow compared to a single‐point liquid distribution and remained stable under varying operating conditions, including different gas and liquid loads.

Comparative Analysis of Uncorrected Rayleigh Fading Channels Models
工程科学与技术, 2009 :In order to compare the complexity and performance of Sum-of-sinusoids (SoS) models for uncorrected Rayleigh fading channels, the second-order statistical formula for deterministic SoS model was derived, which showed that the variance of cross ...

Photothermal bubble: Dynamics, manipulation, and applications
Droplet, EarlyView.As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs
Droplet, EarlyView.Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

Droplet, EarlyView.Curved hydrophobic mesh surfaces enable stable release of large droplets exceeding the capillary length. By tuning surface curvature, porosity, and acceleration, oscillatory breakup is suppressed, producing near‐spherical droplets ideal for high‐precision fluid applications and multiphase flow control.

INTERFERENCE REJECTION OF SIGNALS BY ADAPTIVE MINIMUM MEAN SQUARE ERROR CRITERION OVER RAYLEIGH FADING CHANNELS [PDF]
Journal of Engineering Science and Technology, 2009 Channel time-variation (or fading) is the major source of impairment in digital wireless communications. This occurs due to mobility of the user or of the objects in the propagation environment.
