Investigation of Urban Sprawl Using Spatial Planning Models in Mashhad

open access: yesتحقيقات جغرافيايی, 2018
Introduction and Background:Urban sprawl is a key subject of interest among urban planners and policy–makers, which needs to measure and monitor in order to overcome its impacts. In fact, urban expansion, and sprawl modeling is an interdisciplinary field

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

open access: yesAdvanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Integration of macroeconomic behavioural relationships and the input-output block: Romanian modelling experience

open access: yes
The last version of the Romanian macromodel (Dobrescu 2005b) incorporates the experience accumulated through the utilisation of its previous forms - either experimental (Dobrescu 1991-1994) or operational (Dobrescu 1996-2005a).

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Book Review : A DICTIONARY OF LANGUAGE ACQUISITION: A COMPREHENSIVE OVERVIEW OF KEY TERMS IN FIRST AND SECOND LANGUAGE ACQUISITION

open access: yesEltin Journal, 2014
As  with language, language acquisition (LA), particularly second language acquisition (SLA)  is not simple. SLA  is complex  and paradoxical.  SLA is complex because it cannot be scrutinized using a single approach.

Microstructure‐Controlled Crack Propagation and Fracture Resistance in MoSiBTiC Alloy Revealed by Multiscale Extended Finite Element Method Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

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.
