Investigations of torrefied biomass grindability using a modified Hardgrove test

open access: yesE3S Web of Conferences, 2017
This paper presents results of investigations of torrefied biomass grindability using a modified Hardgrove test. The following types of torrefied biomass were used during the testing: alder chips, palm kernel shells and willow chips. Tests were conducted

Free Monadic Tarski and MMI3-Algebras

open access: yesDemonstratio Mathematica, 2014
MMI3-algebras are a generalization of the monadic Tarski algebras as defined by A. Monteiro and L. Iturrioz, and a particular case of the MMIn+1-algebras defined by A. Figallo.

Third Order Melnikov Functions of a Cubic Center under Cubic Perturbations

open access: yesMathematics, 2022
In this paper, cubic perturbations of the integral system (1+x)2dH where H=(x2+y2)/2 are considered. Some useful formulae are deduced that can be used to compute the first three Melnikov functions associated with the perturbed system.

Radiochemical Studies on the Separation of Cesium, Cobalt, and Europium from Aqueous Solutions Using Zirconium Selenomolybdate Sorbent

open access: yesJournal of Chemistry, 2013
A procedure for removal and separation of Cs, Eu and activation product of Co using zirconium selenomolybdate was developed. Interactions of 134Cs(I), 152,154Eu(III), and 60Co(II) ions from HNO3 acid solutions with zirconium selenomolybdate matrix, dried

Consistency of the national realization of dew-point temperature using NIS standard humidity generators

open access: yesInternational Journal of Metrology and Quality Engineering, 2017
A comparison of two standard humidity generators (two-temperature (2-T) and one-temperature (1-T) generators) that are developed by the National Institute for Standards (NIS) has been performed using a transfer standard chilled-mirror hygrometer and ...

Weaknesses in ENT Battery Design

open access: yesApplied Sciences, 2022
Randomness testing is a key tool to analyse the quality of true (physical) random and pseudo-random number generators. There is a wide variety of tests that are designed for this purpose, i.e., to analyse the goodness of the sequences used.

QCD (&) Event Generators [PDF]

open access: yes, 2005
Recent developments in QCD phenomenology have spurred on several improved approaches to Monte Carlo event generation, relative to the post--LEP state of the art. In this brief review, the emphasis is placed on approaches for 1) consistently merging fixed-

An experimental exploration of Marsaglia's xorshift generators, scrambled

open access: yes, 2016
Marsaglia proposed recently xorshift generators as a class of very fast, good-quality pseudorandom number generators. Subsequent analysis by Panneton and L'Ecuyer has lowered the expectations raised by Marsaglia's paper, showing several weaknesses of ...

Detection of Demagnetization Faults in Axial Flux Permanent-Magnet Synchronous Wind Generators

open access: yesEnergies, 2022
A new method for detecting demagnetization faults in axial flux permanent magnet synchronous wind generators is presented in this study. Demagnetization faults occur in the case of total or partial loss of the magnetic properties of one or more permanent
