ALFIA (Automated Lymphatic Function Imaging Analysis), an algorithm providing quantitative analysis of investigational near-infrared fluorescence lymphatic images, is described. Images from nine human subjects were analyzed for apparent lymphatic propagation velocities and propulsion periods using manual analysis and ALFIA. While lymphatic propulsion was more easily detected using ALFIA than wi...

A laser can be used to propel distant objects. The ability of silicon produce thrust and its propulsive parameters are needed studied in ablative propulsion (ALP). In this work, pure doped with indium were subjected ALP achieve the momentum coupling coefficient specific impulse investigate worth as a propellant. experiment was conducted using Nd:YAG (Quantel Brilliant) operating at fundamental ...

We present an overview of the current state of detonation stability theory and discuss its implications for propulsion. The emphasis of the review is on the exact or asymptotic treatments of detonations, including various asymptotic limits that appear in the literature. The role that instability plays in practical detonation-based propulsion is of primary importance and is largely unexplored, h...

Full scale measurements of the propulsion power, ship speed, wind speed and direction, sea and air temperature from four different loading conditions, together with hind cast data of wind and sea properties; and noon report data has been used to train an Artificial Neural Network for prediction of propulsion power. The model was optimized using a double cross validation procedure. The network w...

We present a detailed analysis of the self-propulsion of a model nanometer-scale motor by reactive molecular dynamics simulations. The nanomotor is decorated with catalysts on only one side that promotes exothermic reactions of the surrounding fuel. Unidirectional drift of the nanomotor is observed that is superimposed on its Brownian motion. The motor response upon the application of external ...

Liquids in the Leidenfrost state were shown by Linke to self-propel if placed on ratchets. The vapour flow below the liquid rectified by the asymmetric teeth entrains levitating drops by viscosity. This effect is observed above the Leidenfrost temperature of the substrate, typically 200°C for water. Here we show that coating ratchets with super-hydrophobic microtextures extends quick self-propu...

As is known the repulsion of the volume elements of an uniformly accelerating charge or a charge supported in an uniform gravitational field accounts for the electromagnetic contribution to the charge’s inertial and gravitational mass, respectively. This means that the mutual repulsion of the volume elements of the charge produces the resistance to its accelerated motion. Conversely, the effect...

Based on the principle of permanent magnet electrodynamic suspension (PMEDS), a new concept maglev car was designed by using rotary magnetic wheels and conductor plate. It has advantages being high-speed, low-noise, environmentally friendly, safe efficient. The PMEDS is to use wheel (EDW) achieve integration levitation force driving force. generated repulsive eddy current field, reaction resist...
