We propose a new approach to capture the volumetric density of dynamic scattering media instantaneously with a single image. The volume is probed with a set of laser lines and the scattered intensity is recorded by a conventional camera. We then determine the density along the laser lines taking the scattering properties of the media into account. A specialized approximation technique reconstru...

Combustion and evaporation processes occurring in a closed chamber can result in significant pressure rise and direct work transfer. The pressure and volumetric changes that accompany such processes allow substantial work potential to be achieved in cyclic nonsteady devices, such as internal combustion engines and pulsed combustion or detonation engines. The ideal pressure gain or work producti...

Background About 3.8% of patients suffering an acute pulmonary embolism will develop chronic thrombembolic pulmonary hypertension (CTEPH). As a consequence of increasing pulmonary pressure and resistance right ventricular systolic and diastolic function deteriorate while right ventricular volumes increase. Pulmonary thrombendarterectomy (PEA) offers a potential cure with excellent longterm outc...

This article describes a process to include in a volumetric model various anatomical and mechanical information provided by different sources. Three stages are described, namely a mesh construction, the non-rigid deformation of the tetrahedral mesh into various volumetric images, and the rasterization procedure allowing the transfer of properties from a voxel grid to a tetrahedral mesh. The met...

Chitosan is a cheap resource, which is widely used in biomedical applications due to its biocompatible and antibacterial properties. In this study, composite nanofibrous membranes of chitosan (CS) and poly(vinyl alcohol) (PVA) loaded with antibiotics at different ratios were successfully fabricated by electrospinning. The composite nanofibers were subjected to further analysis by scanning elect...

Abstract The unusual volumetric properties of both proteated and deuterated water are explored by carefully comparing their developing a heuristic molecular model to describe the behavior. behavior is further relating these other well-known thermodynamic properties.

in this research, the influence of bolt preload on the fatigue strength of 2024-t3 aluminium alloy double lap bolted joints has been studied experimentally and numerically. to do so, three sets of the specimens were prepared and each of them subjected to tightening torque of 1,2.5 and 5 n-m and then fatigue tests were conducted under various cyclic axial load levels. in the numerical method, th...

Hair is one of the crucial elements in representing believable digital humans. It is one of the most challenging elements, too, due to the large number of hairs on a human head, their length, and their complex interactions. Hair appearance, in rendering and simulation, is dominated by collective properties, yet most of the current approaches model individual hairs. In this paper we build on the...

The mechanical properties of cells and tissues play a well-known role in physiology and disease. The model organism Caenorhabditis elegans exhibits mechanical properties that are still poorly understood, but are thought to be dominated by its collagen-rich outer cuticle. To our knowledge, we use a novel microfluidic technique to reveal that the worm responds linearly to low applied hydrostatic ...
