Proses Berpikir Calon Guru Matematika dalam Memecahkan Masalah Geometri Transformasi Berdasarkan Teori John Dewey

Arithmetic
Understanding the thinking process of students has great significance, how students face and solve transformation geometry problems not only reflects the understanding of concepts, but also the ability to think systematically, creatively, and logically ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

Advanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

The geometry of BRS transformations

Illinois Journal of Mathematics, 1990
In 1976 \textit{C. Becchi}, \textit{A. Rouet} and \textit{R. Stora} [Renormalization of gauge theories, Ann. Phys. 98, 287-321 (1976)] noticed that in gauge field theories the effective Lagrangian, which is no longer gauge invariant, is still invariant under a new class of transformations now called BRS transformations \[ sA=d\eta +[A,\eta],\quad s\eta

High‐Entropy Alloy Interlayers Toward Advanced Joining for High‐Performance Structural Applications: Current Progress and Emerging Challenges

Advanced Engineering Materials, EarlyView.
HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

Comparing technology-enhanced and conventional Van Hiele Phased Instruction in advancing learners through Van Hiele levels in transformation geometry

Cogent Education
Developing learners’ geometric reasoning remains a persistent challenge in secondary mathematics education, particularly in transformation geometry, where many learners struggle to progress through the hierarchical Van Hiele levels of geometric thinking.
