The PRIMA Thesaurus for Materials Science and Engineering

open access: yesAdvanced Engineering Materials, EarlyView.
The PRIMA Thesaurus is a structured vocabulary designed to improve how materials science data is described and shared. Developed with input from multiple experts, it enables clear documentation of research workflows, data exchange, and reuse across platforms.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Constructal theory of global circulation and climate [PDF]

open access: yesInternational Journal of Heat and Mass Transfer, 2006
The constructal law states that every flow system evolves in time so that it develops the flow architecture that maximizes flow access under the constraints posed to the flow.

Constructive Order Theory

MLQ, 2001
An upper bound \(s\) of a subset \(Y\) of a poset \(P\) is called a constructive supremum of \(Y\) if there exists a function \(\psi: P\to Y\) such that \(s\leq x\Leftrightarrow \psi(x)\leq x\) for all \(x\in P\). It is proved that the axiom of choice is equivalent to the postulate that every supremum is constructive, and also to the hypothesis that ...

Constructive Many-Body Theory

Reviews in Mathematical Physics, 1994
We review the rôle played by renormalization, particle-number symmetry breaking, Goldstone bosons and the renormalization group in a mathematically rigorous construction of many-Fermion models at temperature zero.

A Personalized Theory of Theory Construction

Personality and Social Psychology Review, 2004
This article describes my personal approach to theory construction. I liken the construction of a theory to the solution of a mathematical puzzle in which the answer is not in the back of the book. I touch on (a) the development of a theoretical perspective, (b) the identification of a specific problem, and (c) the development of a theory to address ...

Constructive set theory

Journal of Symbolic Logic, 1975
This paper is the third in a series collectively entitled Formal systems of intuitionistic analysis. The first two are [4] and [5] in the bibliography; in them I attempted to codify Brouwer's mathematical practice. In the present paper, which is independent of [4] and [5], I shall do the same for Bishop's book [1].

On Theory Construction and Verification

The Accounting Review, 1970
Abstract The article presents an analysis of the nature of empirical theories for the purpose of providing a relief for some current and proposed theories of accounting. The process of theory construction is imperfectly understood.

The Construction of Chaos Theory

Foundations of Science, 2008
The paper provides a logico-mathematical analysis of the concept of chaos from the point of view of a constructivist philosophy of physics. The author argues that deterministic chaos points to a philosophy which asserts that chaotic systems are no less measurable than other physical systems where predictable and non-predictable phenomena intermingle in

THE CONSTRUCTIVE THEORY OF INVARIANTS

Mathematics of the USSR-Izvestiya, 1982
In this paper we find an explicit upper bound on the number of elements of a minimal homogeneous system of generators of the algebra of invariants of an arbitrary connected semisimple linear group over an algebraically closed field of characteristic zero. We also show that the approach to the solution of this problem proposed by Dieudonn?
