Removing Oxide Layers and Retaining Oxide‐Free Steel Surfaces by Polishing in Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
In this study, the efficacy of wet mechanical polishing under an oxygen‐free atmosphere for deoxidation and the retention of an oxide‐free steel surface are elucidated using X‐ray photoelectron spectroscopy. The methodology proved successful; however, the results were highly dependent on the preparation of the solvents used to clean the samples after ...

TEACHING PROBLEM SOLVING IN MATHEMATICS LEARNING: REFLECTION FROM PISA AND TIMSS RESULTS OF THE STUDENTS OF INDONESIA [PDF]

open access: yes, 2014
The quality of mathematics education in Indonesia is still low. This is at least acquired from the attainment of the students of Indonesia participating in international assessments, such as PISA and TIMSS.

Evaluating Energy Absorption Performance of Filled Lattice Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Reading in a foreign language: Strategic variation between readers of differing proficiency [PDF]

open access: yes, 2002
For university language students who are required to deal with literary texts for linguistic or literary purposes, there is hardly any transitional stage between short adapted expository texts, read in the early stages of language learning, and complex

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.

Students’ Problem Solving Strategies in Problem Solving-mathematics Classroom

open access: yesProcedia - Social and Behavioral Sciences, 2014
AbstractTeaching approaches in mathematics classrooms have been changed to a more insight-based problem oriented process during the last decade (van Oers, 2002). In addition, problem solving requires a variety of skills including interpreting information, planning and methodical working, checking results and trying alternative strategies (Muir, Beswick,

Bounded Rationality and Heuristics in Humans and in Artificial Cognitive Systems [PDF]

open access: yes, 2019
In this paper I will present an analysis of the impact that the notion of “bounded rationality”, introduced by Herbert Simon in his book “Administrative Behavior”, produced in the field of Artificial Intelligence (AI).

Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.
