Simulation Tools [PDF]

open access: yes, 2018
Simulation can enable several developments in the field of intelligent vehicles. This chapter is divided into three main subsections. The first one deals with driving simulators. The continuous improvement of hardware performance is a well-known fact that is allowing the development of more complex driving simulators.

A prospective randomized crossover manikin study comparing GlideScope® video laryngoscopy and direct laryngoscopy for impacted fish bone removal in a simulated difficult airway

open access: yesHong Kong Journal of Emergency Medicine, Volume 33, Issue 2, April 2026.
Abstract Background Fish bone ingestion is a common emergency presentation. Direct laryngoscopy (DL) is the conventional bedside technique, but it can be limited in anatomically challenging airways. Video laryngoscopy (VL) improves glottic visualization for intubation, yet its role in foreign body retrieval is unclear. Because difficult airway features

Microwave detection of buried mines using non-contact, synthetic near-field focusing [PDF]

open access: yes, 2001
Existing ground penetrating radars (GPR) are limited in their 3-D resolution. For the detection of buried land-mines, their performance is also seriously restricted by `clutter'. Previous work by the authors has concentrated on removing these limitations

Optimization of Microfibrillated and Nanofibrillated Cellulose Coating to Improve Performance of Paperboard Intended for Food Packaging Applications

open access: yesPackaging Technology and Science, Volume 39, Issue 4, Page 351-366, April 2026.
This study aims to optimise the application methods of a biobased suspension of micro/nano cellulose fibrils from agro‐biomass subjected to high‐pressure homogenisation. Two methods were selected, bar coating (BC) and spray coating (SC), and were tested using an LF factorial design with 3 levels and 2 factors.

Enhanced Active Packaging Properties Through the Incorporation of Pomegranate Seed Oil Micro‐ and Nanoparticles

open access: yesPackaging Technology and Science, Volume 39, Issue 4, Page 335-350, April 2026.
Biodegradable cassava starch films were developed incorporating micro‐ and nanoencapsulated pomegranate seed oil (PSO). The films exhibited enhanced mechanical flexibility, antioxidant activity and UV‐barrier properties. Particle size influenced the functional behaviour, highlighting lipid encapsulation as a key strategy to stabilize bioactive ...

Recent Advances in Hafnium Oxide Nanomaterials: From Controlled Synthesis, Structure, and Surface Engineering to Biomedical Applications

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Hafnium oxide (HfO2) nanoparticles (NPs), derived from a rare‐metal element, have gained increasing attention as a versatile class of functional nanostructures with unique optical, dielectric, and surface properties that enable diverse biomedical applications. As a representative rare‐metal oxide, HfO2 NPs with well‐defined architectures offer

Laboratory experiments and models of diffusive emplacement of ground ice on Mars [PDF]

open access: yes, 2009
Experiments demonstrate for the first time the deposition of subsurface ice directly from atmospheric water vapor under Mars surface conditions. Deposition occurs at pressures below the triple point of water and therefore in the absence of a bulk liquid ...

Polarization Changes in Lunar Simulant Soil: The Role of Incident, Reflection, and Off‐Plane Angles

open access: yesEarth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Observing the polarization of the lunar regolith is essential for obtaining detailed information about the composition and characteristics of lunar soil. Observations conducted via lunar orbiters facilitate polarization measurements over wide areas; however, achieving very high‐resolution imaging requires either a large optical system or a ...
