Preservice Secondary Mathematics Teacher's Views about Using Multiple Representations in Mathematics Instruction

open access: yesProcedia - Social and Behavioral Sciences, 2012
AbstractThe purpose of this study is to determine the preservice secondary mathematics teacher's (PSMT's) views about using multiple representations (MRs) in mathematics lessons. 25 PSMTs were participated in this qualitative study by planning and preparing lessons related to mathematics curriculum attainments.

X‐Ray Tomography Analysis of Damage Mechanisms in Metal Matrix Syntactic Foams During Compression

open access: yesAdvanced Engineering Materials, EarlyView.
In situ synchrotron X‐ray tomography is used to investigate the internal damage mechanisms of AlSi12 metal matrix syntactic foam with ceramic hollow spheres during compressive loading. It is concluded that a homogeneous distribution of the second‐phase filler material results in a sequential collapse in a localized region; this leads to controlled and ...

On mixed multiplicities of ideals [PDF]

open access: yes, 2015
Let R be the local ring of a point on a variety X over an algebraically closed field k. We make a connection between the notion of mixed (Samuel) multiplicity of m-primary ideals in R and intersection theory of subspaces of rational functions on X which ...

Enabling Digital Continuity in Virtual Manufacturing for Eco‐Efficiency Assessment of Lightweight Structures by Means of a Domain‐Specific Structural Mechanics Language: Requirements, Idea and Proof of Concept

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a solver‐agnostic domain‐specific language (DSL) for computational structural mechanics that strengthens interoperability in virtual product development. Using a hierarchical data model, the DSL enables seamless exchange between diverse simulation tools and numerical methods.

Instability and Singularity of Projective Hypersurfaces

open access: yes, 2017
In this paper, we will show that the Hesselink stratification of a Hilbert scheme of hypersurfaces is independent of the choice of Pl\"ucker coordinate and there is a positive relation between the length of Hesselink's worst virtual 1-parameter subgroup ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Exponential decay of eigenfunctions and generalized eigenfunctions of a non self-adjoint matrix Schr\"odinger operator related to NLS

open access: yes, 2007
We study the decay of eigenfunctions of the non self-adjoint matrix operator $\calH = (\begin{smallmatrix} -\Delta +\mu+U & W \W & \Delta -\mu -U \end{smallmatrix})$, for $\mu>0$, corresponding to eigenvalues in the strip ...

ONTOLOGY OF THE LINGUISTIC SPACE OF TRUTH IN ALAIN BADIOU’S PHILOSOPHY

open access: yesЕпістемологічні дослідження у філософії, соціальних і політичних науках
The article offers an ontological analysis of the linguistic space of truth in Alain Badiou’s philosophy through the prism of the relationship between mathematics as ontology, the concept of the event, and truth procedures.
