Generating ultrashort visible light pulses based on multidimensional solitary states in gas-filled hollow core fiber

open access: yesAPL Photonics, 2023
Multidimensional solitary states (MDSS) are self-sustaining light wave packets confined in multiple dimensions in multimode fibers. In this work, we experimentally demonstrate the generation of MDSS, driven by a few hundreds of femtoseconds (fs) of long ...

The Optimum-efficiency Beam Multiplier for an Arbitrary Number of Output Beams and Power Distribution

open access: yesJournal of Telecommunications and Information Technology, 2017
This paper deals with phase gratings working in the paraxial domain. The profile of the optimum-efficiency beam multiplier with an arbitrary number of output diffraction orders is derived in an analytic form by exploiting methods from the calculus of ...

Phase-I monitoring of standard deviations in multistage linear profiles

open access: yesJournal of Industrial Engineering International, 2017
In most modern manufacturing systems, products are often the output of some multistage processes. In these processes, the stages are dependent on each other, where the output quality of each stage depends also on the output quality of the previous stages.

Efferent Vestibular Neurons Show Homogenous Discharge Output But Heterogeneous Synaptic Input Profile In Vitro. [PDF]

open access: yesPLoS ONE, 2015
Despite the importance of our sense of balance we still know remarkably little about the central control of the peripheral balance system. While previous work has shown that activation of the efferent vestibular system results in modulation of afferent ...

Profile-Decomposing Output of Multi-Channel Odor Sensor Array [PDF]

open access: yesECS Meeting Abstracts, 2020
Introduction This paper proposes a method for profile-decomposing the output from a segmented multi-subpixels 2-D sensor array, that is, a method for obtaining the spatial concentration distribution of each component odor using the output from the image sensor.

Investigation of Variable Switching Frequency in Finite Control Set Model Predictive Control on Grid-Connected Inverters

open access: yesIEEE Open Journal of Industry Applications, 2021
Finite control set model predictive control (FCS-MPC) has been widely studied and applied to the power converters and motor drives. It provides the power electronics system with fast dynamic response, nonlinear system formulation, and flexible objectives
