Fundamental Relations in Monopolistic Competition of Dixit-Stiglitz Type

EIRP Proceedings, 2010
This work aims at clarifying the main theoretical aspects of the monopolistic competition Dixit-Stiglitz type; this is considered a reference point in economics theory, and also a basis in the prolific field, that is New Economics Geography.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Some fundamental postulates governing relations between monetary (banking) finances and monetary law [PDF]

Zbornik Radova Pravnog Fakulteta u Nišu, 2019
The connection between science of monetary law and science of monetary finances is so significant that in today's economic and social developments it transcends the very concept and the dialectic of multidisciplinarity and its function and receives a ...

i-Open Sets in Bitopological Spaces [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2018
In this paper, we defined i-open sets and i-star generalized w-closed sets in bitopological spaces  by using the definition of i-open sets in topological space  (see[6]). We present some fundamental properties and relations between these classes of sets,

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

Advanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Fluctuation-dissipation theorem and fundamental photon commutation relations in lossy nanostructures using quasinormal modes

Physical Review Research, 2020
We provide theory and formal insight on the Green function quantization method for absorptive and dispersive spatial-inhomogeneous media in the context of dielectric media.

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response

Advanced Engineering Materials, EarlyView.
A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...

The spin-statistics connection in classical field theory

, 2006
The spin-statistics connection is obtained for a simple formulation of a classical field theory containing even and odd Grassmann variables. To that end, the construction of irreducible canonical realizations of the rotation group corresponding to ...

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

Advanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.
