THE USE OF SOME PRINCIPLES FROM AXIOMATIC DESIGN IN THE CASE OF AN EQUIPMENT FOR THE STUDY OF ELECTROCHEMICAL MACHINING

open access: yesNonconventional Technologies Review, 2022
Electrochemical machining is usually included in the wider group of non-conventional machining methods. This method is based on the material removal from the workpiece as a result of chemical reactions between the electrolyte and the material of the ...

Logical independence and quantum randomness [PDF]

open access: yes, 2010
We propose a link between logical independence and quantum physics. We demonstrate that quantum systems in the eigenstates of Pauli group operators are capable of encoding mathematical axioms and show that Pauli group quantum measurements are capable of ...

The Weak Core, Partition‐Based Universal Stability, and Their Risk Associations Through A Partial Order

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT We are concerned with the stability of a transferable‐utility cooperative (TU) game. First, the concept of core can be weakened so that the blocking of changes is limited to only those with multilateral backings. This principle of consensual blocking, as well as the traditional core‐defining one of unilateral blocking and one straddling in ...

Constructing Banaschewski compactification without Dedekind completeness axiom

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
The main aim of this paper is to provide a construction of the Banaschewski compactification of a zero-dimensional Hausdorff topological space as a structure space of a ring of ordered field-valued continuous functions on the space, and thereby exhibit ...

Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant Veratrum grandiflorum

open access: yesNordic Journal of Botany, EarlyView.
Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...

Contrasting effects of temperature across trophic levels in geothermally warmed soil food webs

open access: yesOikos, EarlyView.
Global warming is altering the structure and dynamics of ecological communities, with significant consequences for soil food webs. Rising temperatures are expected to accelerate metabolic rates in organisms, potentially altering species interactions, and the structure and energetics of food webs.

A step into the shadows: Evolutionary shifts in fruit structure and dispersal strategies in Asian mycoheterotrophic Ericaceae

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
This study examines how the fruits of non‐photosynthetic forest plants in the Monotropoideae (Ericaceae) have evolved into the diversity observed today. By analyzing four Asian species, we identified a shift from dry, dehiscent fruits that release seeds into the air to fleshy, berry‐like fruits adapted for animal dispersal.

On absolutely independent group axioms

open access: yesMonatshefte f�r Mathematik, 1967
In this paper we prove three theorems, each of which gives a set of absolutely independent group axioms. Theorem 2 is an extension of Morgado's theorem obtained by using a weaker associativity axiom. The axioms of Theorem 3 are the first absolutely independent group axioms we have encountered for ,,~ich there is no k such that the axioms are absolutely

An objective Bayesian method for including parameter uncertainty in ensemble model output statistics

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Conventional model output statistics and ensemble model output statistics methods for calibrating ensemble forecasts lead to severe underestimation of the probabilities of ensemble extremes (in blue). This is because they ignore statistical parameter uncertainty.

A New Arithmetically Incomplete First- Order Extension of Gl All Theorems of Which Have Cut Free Proofs [PDF]

open access: yes, 2016
Reference [12] introduced a novel formula to formula translation tool (“formulators”) that enables syntactic metatheoretical investigations of first-order modal logics, bypassing a need to convert them first into Gentzen style logics in order to rely on ...
