Constructing function domains in NiTi shape memory alloys by additive manufacturing

open access: yesVirtual and Physical Prototyping, 2022
Additive manufacturing (AM) is an orderly construction process involving track-by-track melt pools, which can modulate three characteristic zones between two adjacent melt pools: the heat-affected zone, transition zone, and cellular grain zone.

On the Alienation of Multiplicative and Additive Functions

open access: yesAnnales Mathematicae Silesianae
Given S a semigroup. We study two Pexider-type functional equations fxy+gxy=fx+fy+gxgy,    x, y∈S,f\left( {xy} \right) + g\left( {xy} \right) = f\left( x \right) + f\left( y \right) + g\left( x \right)g\left( y \right), \;\;\;\;x,\;y \in S, and ...

The Combinatorial World (of Auctions) According to GARP

open access: yes, 2015
Revealed preference techniques are used to test whether a data set is compatible with rational behaviour. They are also incorporated as constraints in mechanism design to encourage truthful behaviour in applications such as combinatorial auctions. In the

Conditional Equations Related to Drygas Functional Equations

open access: yesAnnales Mathematicae Silesianae
We determine the solutions of the conditional Drygas equation for functions f1 and f2 that satisfy (y2 + y)f1(x) = (x2 + x)f2(y) for all (x, y) ∈ ℝ2 under the additional conditions y = x2, or y = log(x), x > 0 or y = exp(x).

Consistency Analysis and Priorities Deriving for Pythagorean Fuzzy Preference Relation in the “Computing in Memory”

open access: yesIEEE Access, 2020
Pythagorean fuzzy set, characterized by membership function and non-membership function, has received increasing attention in recent years. In this paper, a new approach to decision making is proposed based on Pythagorean fuzzy preference relation and ...

When non-extensive entropy becomes extensive

open access: yes, 2001
Tsallis' non-extensive entropy $S_q$ enables us to treat both a power and exponential evolutions of underlying microscopic dynamics on equal footing by adjusting the variable entropic index $q$ to proper one $q^*$. We propose an alternative constraint of

Sub-Additive Aggregation Functions and Their Applications in Construction of Coherent Upper Previsions

open access: yesMathematics, 2020
In this paper, we explore the use of aggregation functions in the construction of coherent upper previsions. Sub-additivity is one of the defining properties of a coherent upper prevision defined on a linear space of random variables and thus we ...

A General System of Functional Equations Deriving From Additive, Quadratic, Cubic, and Quartic Mappings

open access: yesJournal of Mathematics
In the current study, we introduce a system of functional equations (FEs) deriving from the mixed type additive–quadratic and the mixed-type cubic–quartic FEs which describes a multimixed additive–quadratic–cubic–quartic mapping.

Some properties of extended remainder of Binet's first formula for logarithm of gamma function

open access: yes, 2010
In the paper, we extend Binet's first formula for the logarithm of the gamma function and investigate some properties, including inequalities, star-shaped and sub-additive properties and the complete monotonicity, of the extended remainder of Binet's ...
