Engineering models for turbine wake velocity deficit and wake deflection. A new proposed approach for onshore and offshore applications

Journal of Physics: Conference Series, 2019
Abstract An engineering wake model based on the Ainslie model is proposed. The eddy viscosity term associated with momentum diffusivity is modified to take into account the effects of atmospheric stability. The parameters used are typically available from high-quality on-site measurement campaigns and the effects of atmospheric stability

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

Deep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

An Analytical Model of Wake Deflection Due to Shear Flow

, 2010
The main motivation behind this work is to create a purely analytical engineering model for wind turbine wake upward deflection due to shear flow, by developing a closed form solution of the velocity field due to an oblique vortex ring. The effectiveness of the model is evaluated by comparing the results with those of a free-wake model. The solution of

Optical and Chiroptical Properties of a Green‐Emitting Tb(III) Complex Embedded in Silica Nanoparticles

European Journal of Inorganic Chemistry, EarlyView.
The SiO2 matrix improves the luminescence efficiency of the chiral Tb(bpcd)Cl complex by mitigating multiphonon relaxation, without compromising its chiroptical response. A spectroscopic investigation of water‐soluble and chiral Tb(III) complexes with N,N′‐bis(2‐pyridylmethyl)‐trans−1,2‐diaminocyclohexane‐N,N′‐diacetic acid, embedded in water ...

Low‐intensity focused ultrasound neuromodulation for drug‐resistant epilepsy: A randomized, sham‐controlled crossover trial

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to evaluate the safety, feasibility, and efficacy of low‐intensity focused ultrasound (LIFU) as a noninvasive neuromodulation technique in patients with drug‐resistant epilepsy (DRE). Methods In this pilot, single‐blind, randomized sham‐controlled crossover trial, 12 patients with DRE underwent both LIFU and

A double-Gaussian wake model considering yaw misalignment

International Journal of Renewable Energy Development
A wake steering has been known to effectively increase wind farm production by deflecting the upstream turbines’ wakes via yaw misalignment, thus minimizing their negative impacts on the downstream turbines' performances.

Nucleus basalis functional connectivity aberrations in temporal lobe epilepsy and improvements after successful epilepsy surgery

Epilepsia, EarlyView.
Abstract Objective Resective surgery achieves seizure freedom in approximately 60%–80% of patients with drug‐resistant temporal lobe epilepsy (TLE), yet the extent to which seizure cessation permits recovery of disrupted functional brain networks remains unclear.
