To describe the use of anterior segment optical coherence tomography (OCT) in studying dynamic dark-light changes chamber angle.Thirty-seven normal subjects with open angles on dark-room gonioscopy and 18 narrow were analyzed. The anterior-chamber angle captured real-time video recording. opening distance (AOD500) trabecular iris space area (TISA500) nasal pupil diameter each representative serial images measured. Linear regression analysis was performed to investigate association between...
A sliding mode controller is proposed for the attitude control of spacecraft reorientation with constraints. By introducing a potential function, novel function designed. With structure uniqueness equilibrium and fixed-time convergence are rigorously proven. Another advantage that feasibility constraints can be proven not only on surface but also outside it. Moreover, singularity issue resolved. Effectiveness method demonstrated by carrying out two numerical simulation.
Accurate short-term load forecasting (STLF) is essential for power grid systems to ensure reliability, security and cost efficiency. Thanks advanced smart sensor technologies, time-series data related can be captured STLF. Recent research shows that deep neural networks (DNNs) are capable of achieving accurate STLP since they effective in predicting nonlinear complicated data. To perform STLP, existing DNNs use time-varying dynamics either past consumption or correlated features such as...
purpose. To evaluate the structure/function relationship between visual field sensitivity and retinal nerve fiber layer (RNFL) thickness measured by StratusOCT (Carl Zeiss Meditec, Inc., Dublin, CA) GDx VCC (Laser Diagnostic Technologies, San Diego, CA). methods. Eighty-nine subjects (27 who had healthy eyes, 21 were glaucoma suspect, 41 glaucoma) enrolled in this cross-sectional study. RNFL was using VCC, (VF) examined Humphrey VF analyzer. The sensitivity—expressed terms of mean deviation...
Abstract Background Whereas lowering the intraocular pressure (IOP) can slow optic nerve degeneration in glaucoma, many patients with glaucoma continue to develop progressive loss vision despite a significant reduction IOP. No treatment has been shown be effective for neuroprotection glaucoma. We set out conduct randomized controlled trial investigate whether nicotinamide riboside (NR), adenine dinucleotide precursor, is primary open-angle (POAG). hypothesize that treated NR have slower rate...
This paper studies the effects of channel leadership and information asymmetry on supply chain coordination (SCC) a single-manufacturer (M) single-retailer (R) chain, which sells product with general stochastic price-dependent-demand function. Three all-units quantity discount (QD) contracts are examined: (1) manufacturer-led QD (MQD); (2) retailer-led (RQD); (3) vendor managed inventory (VQD), represent different leaderships. The problems constructed as multistage sequential games. We find...
In beamformer design, the microphone array configuration is often prescribed and filter coefficients are varied in order to improve on noise reduction performance. However, positions of elements play an important role overall performance should be optimized at same time. This problem addressed this paper. understand improvement through location movements, we first look design with infinite length, which gives limit for finite length designs. When finite, both placement decision variables....
For over two decades, speech control mechanisms have been widely applied in manufacturing systems such as factory automation, warehouse and industrial robotic for decades. To implement controls, a commercial recognizer is used the interface between users automation system. However, users' commands are often contaminated by environmental noise which degrades performance of recognition controlling systems. This paper presents multichannel signal enhancement methodology to improve recognizers....
