Comparison of diffusion models for description of osmotic dehydration of radish slices dipped in brine [PDF]

open access: yesEngenharia Agrícola, 2015
This paper aims at describing the osmotic dehydration of radish cut into cylindrical pieces, using one- and two-dimensional analytical solutions of diffusion equation with boundary conditions of the first and third kind. These solutions were coupled with

Costs evaluation methodic of energy efficient computer network reengineering

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2016
A key direction of modern computer networks reengineering is their transfer to a new energy-saving technology IEEE 802.3az. To make a reasoned decision about the transition to the new technology is needed a technique that allows network engineers to ...

Analytic modelling of biotransistors

open access: yesIET Circuits, Devices & Systems, 2008
The possibility of using devices based on field-effect principles for detecting DNA hybridisation events is an attractive and low-cost alternative to optical reading techniques. Experiments have shown that a change in the threshold voltage of a few millivolts can be attributed to successful hybridisation of targets to probe oligonucleotides tethered on

Analyticity in Hubbard Models [PDF]

open access: yesJournal of Statistical Physics, 1999
The Hubbard model describes a lattice system of quantum particles with local (on-site) interactions. Its free energy is analytic when βt is small, or βt^2/U is small; here, βis the inverse temperature, U the on-site repulsion and t the hopping coefficient.

ANALYTIC MODELING OF STARSHADES [PDF]

open access: yesThe Astrophysical Journal, 2011
External occulters, otherwise known as starshades, have been proposed as a solution to one of the highest priority yet technically vexing problems facing astrophysics - the direct imaging and characterization of terrestrial planets around other stars. New apodization functions, developed over the past few years, now enable starshades of just a few tens
