All‐Optically Driven Optofluidic Light Modulator

open access: yesAdvanced Optical Materials, EarlyView.
In this work, an all‐optically driven optofluidic light modulator is developed, based on the optical actuation of waveguided beams by liquid crystals confined in a microfluidic channel. The photovoltaic effect in lithium niobate is employed to control the alignment of the liquid crystal in the microfluidic channel underneath by a light‐induced electric

Dynamic Resource Management using Operating System-Level Virtualization [PDF]

open access: yesarXiv, 2013
This thesis expands upon an existing system called Golondrina that performs autonomic workload management among a cluster of hardware nodes running operating system-level virtualization. Golondrina works by identifying localized resource stress situations and attempting to dissipate them by reallocating system resources and, if necessary, migrating or ...

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

open access: yesAdvanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

A Force Myography (FMG) Armband Based on Micro‐Structured Textile‐Pressure Sensors for Human‐Machine Interface (HMI)

open access: yesAdvanced Sensor Research, EarlyView.
This study introduces a textile‐based capacitive pressure sensor featuring a triangular prism microstructure, which significantly enhances sensitivity to 5.52% kPa−¹ and supports a wide sensing range up to 330 kPa. The sensor's performance is validated in a 4‐channel capacitive pressure‐based force myography (cFMG) armband for gesture recognition ...
