Write or Radiate? Inscribed Mass vs. Electromagnetic Channels
نویسنده
چکیده
We consider information flow via physical transport of inscribed media through space and compare it to information flow via electromagnetic radiation. Somewhat counterintuitively for point to point links, physical transport of inscribed mass is often energetically more efficient by many orders of magnitude than electromagnetic broadcast. And perhaps more surprising, even in a broadcast setting (depending on the receiver density) inscribed mass transport is still energetically more efficient. We discuss the implications of these results for terrestrial telecommunications networks as well as point to point and broadcast communication over great distances with loose delay constraints.

متن کاملDedicated to Irene Z. CLASSICAL TUNNELING AS THE RESULT OF RETARDATION IN CLASSICAL ELECTRODYNAMICS: NONRELATIVISTIC CASE
The problem of radiation reaction in classical electrodynamics is still discussed in the literature (for ex. see [1]). This problem can be formulated in the following way: it is known that classical charged body moving with acceleration must radiate. Thus there is back reaction of outgoing electromagnetic waves. But what quantity feels this back reaction pure mechanical mass of a charged body o...
متن کاملInvestigating the Efficiency of Two Writing Strategies Among Iranian EFL Learners: Translated Writing vs. Reading to Write
This study explored the effects of 2 different types of strategies—translatedwriting vs. reading to write—in the writings of some of Iranian EFL learners inEsfahan Payamenoor University. The results showed no significant differences inthe students’ writings (in the 2 experimental groups and 1 control group) for thepretest topic. With respect to the posttest, the results, however, indicated that...
متن کاملElectromagnetic Radiation from the acceleration of charged particles
Charged particles are held to radiate as a function of their acceleration in some situations. One well-known exception to this is in atomic structures, and some believe that classical electromagnetism cannot be used to describe atomic behaviour because it requires that an electron radiates energy under acceleration. This is naive, for if accelerating charges radiate under some conditions but no...
متن کاملAlgorithm for finding the largest inscribed rectangle in polygon
In many industrial and non-industrial applications, it is necessary to identify the largest inscribed rectangle in a certain shape. The problem is studied for convex and non-convex polygons. Another criterion is the direction of the rectangle: axis aligned or general. In this paper a heuristic algorithm is presented for finding the largest axis aligned inscribed rectangle in a general polygon. ...
