I propose a general class of space-times whose structure is governed by observer-independent scales of both velocity (c) and length (Planck length), and I observe that these space-times can naturally host a modification of FitzGerald-Lorentz contraction such that lengths which in their inertial rest frame are bigger than a " minimum length " are also bigger than the minimum length in all other ...

When a battery-powered robot needs to operate for a long period of time, optimizing its energy consumption becomes critical. Driving motors are a major source of power consumption for mobile robots. In this paper, we study the problem of finding optimal paths and velocity profiles for car-like robots so as to minimize the energy consumed during motion. We start with an established model for ene...

This Letter deals with an analysis of bending edge waves propagating along the free edge of a Kirchhoff plate supported by a Winkler foundation. The presence of a foundation leads to a non-zero cut-off frequency for this wave, along with a local minimum of the associated phase velocity. This minimum phase velocity corresponds to a critical speed of an edge moving load and is analogous to that i...

A three-dimensional finite difference model was employed for the borehole ground heat exchanger to perform a thermal response test analysis using the parameter estimation technique. This allowed the groundwater velocity to be determined simultaneously together with the ground thermal conductivity and the borehole thermal resistance. It was found that the estimated groundwater velocity scattered...

thin layer drying of russian olive (elaeagnusan gastifolial l.) fruit using a hot air dryer in order to calculate effective moisture diffusivity, activation energy and energy consumption has been evaluated in this article. the selected variables included three levels of air velocity of 0.5, 1 and 1.5 m/s and three air temperature levels of 50, 60 and 70°c. increased air temperature increased ef...

Background/Objective: Numerous studies have reported restoring motor function through spinal cord stimulation in a rodent injury model; however, replicating sensory information has not been thoroughly tested.We previously trained rats to detect artificial sensations which lead the question if this can be generated injured rat. Our study begins address by first validating model test. hypothesis ...

Abstract The term lacus generally identified the public fountains in main streets of ancient Roman towns, providing for population daily water demand. simplest consisted a stone basin and spout stone, concealing one or two supply pipes. 35 street this type have been surveyed Pompeii, to gather information on their its variation time. A new method was devised calculating discharge through overfl...

In this study, the pressure drop for the binary mixtures of particles differing in size and density in a pseudo-2D spouted bed was experimentally studied. A binary mixture of solid particles including sand, Gypsum, and polyurethane was used in the experimental setup. Effects of static bed height, cone angle, particles diameter, and a particles weight fraction on the bed pressure drop were e...

the present study investigated the influence of air temperature and velocity on the drying kinetics and specific energy consumption during fluidized bed drying of soybean at 80, 100, 120 and 140ºc and airflow rates of 1.8, 3.1 and 4.5 m s-1. six mathematical models for describing the fluidized bed drying behavior were investigated. the value of the drying rate coefficient (k) increased with inc...
