A Mechanism for Analyzing the Energy Consumption and Environmental Impact of LoRa Sensors Over Time
An SPN‐based mechanism, validated against NS‐3 with MAPE below 0.3%, reveals how packet generation rate and spreading factor shape LoRa sensor lifetime, energy consumption, and operational CO2$$ {}_2 $$ emissions, supporting sustainable planning of large‐scale IoT deployments. ABSTRACT Long Range (LoRa) sensors are widely adopted in Internet of Things (

Study of a Frugal Design Picosecond Laser System for Laser‐Assisted Corneal Surgery
Stromal surface after extraction of the lamella cut with the studied frugal picosecond laser source. ABSTRACT Femtosecond lasers have long been the gold standard for corneal laser‐assisted surgery, but their high cost limits widespread use. This study challenges their supremacy by investigating a cost‐effective alternative: a frugal all‐fiber ...

Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures
A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO 2 and the v2 mode of CH 4. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH 4 and CO 2 spectra in a diffusion flame.

Ultra‐High Isolation Decoupling and Matching Network for mmWave Antennas in Near‐Range FMCW Radars
ABSTRACT A decoupling and matching network (DMN) based on substrate integrated coaxial line technique is proposed to suppress the mutual coupling between a pair of transmitting and receiving antennas operating at 35 GHz. The distorted radiation patterns, typically observed in closely spaced antennas, were improved by introducing carefully designed ...

Chirp-free optical modulation using a silicon push-pull coupling microring
We propose a silicon ring-based optical modulation method to perform chirp-free optical modulations. In this scheme, we locate the light to be modulated at the resonance of the ring and tune the coupling coefficient between the ring and the straight ...

Abstract Estimating suspended sediment concentration (SSC) in river channels is essential for understanding hydro‐sedimentological processes, managing water quality, and conserving aquatic ecosystems. This study evaluated different empirical equations to estimate SSC in the lower Madeira River and analyzed its hydro‐sedimentary dynamics based on MODIS ...

ABSTRACT To reduce the need for scheduled wind turbine blade inspections and large‐scale repairs, a novel distributed acoustic sensing system for monitoring the structural health of wind turbine blades is proposed. This integral passive monitoring system utilizes a sparse array of in‐blade multimodal sensors and a single blade‐external downtower sensor,
