Delay Information in Virtual Queues : A Large-Scale Field Experiment on a Maj…

The growing adoption of virtual queues in the service and retail industries has been greatly accelerated in recent times. In collaboration with a major ride-sharing platform, we study how the wait …

Fiber-Tip Gas Transducer Based on All-Optical Photoacoustic Spectroscopy

In this paper, a fiber-tip all-optical photoacoustic (PA) transducer is demonstrated. The transducer is integrated by a silicon cantilever, a single optical fiber and a silicon dioxide tube. The ex…

All-Fiber Laser-Self-Mixing Interferometer With Adjustable Injection Intensit…

In this article, we propose an all-fiber self-mixing velocimeter based on a DBR fiber laser with adjustable injection intensity for the first time, and theoretically and experimentally explore the …

High-Sensitivity Fiber-Optic Low-Frequency Acoustic Detector Based on Cross-C…

Fiber-optic acoustic sensors based on Fabry-Perot (F-P) interference structure have advantages of compact structure, high sensitivity, convenience to manufacture and immunity to electromagnetic int…

The Reference Effect of Delay Announcements : A Field Experiment

We explore whether customers are loss averse in time and how delay information may impact such reference-dependent behavior using observational and field experiment data from two call centers of an…

Call to Duty : Just-in-Time Scheduling in a Restaurant Chain

Just-in-time scheduling has become ubiquitous in the service industries. Although effective in reducing staffing level, hence labor cost, the potential impact of just-in-time scheduling on workersâ…

Low-Noise Balanced Photoreceiver With InP-on-Si Photodiodes and SiGe BiCMOS T…

FPGA Implementation of Rate-Adaptable Prefix-Free Code Distribution Matching …

In this work, we implement a rate-adaptable (RA) prefix-free code distribution matching (PCDM) encoder in a field-programmable gate array (FPGA). The implemented RA-PCDM encoder supports a wide ran…

High-Speed Evanescently-Coupled Waveguide Type-II MUTC Photodiodes for Zero-B…

Fast Demodulation of Fiber Bragg Grating Wavelength From Low-Resolution Spect…

This paper presents a fast demodulation algorithm to determine fiber Bragg grating (FBG) from spectra acquired by low wavelength resolution spectrometers. A modified and improved Buneman frequency …
