Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

Mosaicing of multiplanar regions through autonomous navigation of off-the-shelf quadcopter

IET Cyber-systems and Robotics, 2019
The real world is made up of multiplanar and curved surfaces. Imaging such surfaces with an orthographic view using a handheld camera is tiring if the scene encompasses a view larger than the camera field of view.

Death on camera

BMJ, 1998
Rabbi Julia Neuberger looks at how death and dying are now openly discussed in the media and argues that the medical profession needs to keep up with the trend A few weeks ago, the news that Lord Winston was making a television series in which someone was to be filmed in the process of dying led to much media coverage.

Evaluating the Effectiveness of Red Light Running Camera Enforcement in Cedar Rapids and Developing Guidelines For Selection and use of Red Light Running Countermeasures, Midwest Transportation Consortium, Final Report November 2011. [PDF]

, 2011
Red light running (RLR) is a problem in the US that has resulted in 165,000 injuries and 907 fatalities annually. In Iowa, RLR-related crashes make up 24.5 percent of all crashes and account for 31.7 percent of fatal and major injury crashes at ...

Sensor for Distance Measurement Using Pixel Grey-Level Information

Sensors, 2009
An alternative method for distance measurement is presented, based on a radiometric approach to the image formation process. The proposed methodology uses images from an infrared emitting diode (IRED) to estimate the distance between the camera and the ...

Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

Advanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Direct comparison of herpetofaunal camera, pitfall, and funnel trapping in the upland habitats of Florida, USA

Wildlife Society Bulletin
Determining the best method to survey species of interest is critical for successful field research projects. When sampling herpetofauna, pitfall and funnel trapping allow a researcher to examine multiple individuals but require considerable field effort
