Meshing of Surfaces [PDF]

open access: yes, 2006
Meshing is the process of computing, for a given surface, a representation consisting of pieces of simple surface patches, like triangles. This survey discusses all currently known surface (and curve) meshing algorithms that come with correctness and ...

Optimizing NiMo Electrocatalyst Coatings for Hydrogen Evolution in Alkaline Electrolysis With The Machine Learning‐Guided Autonomous Platform CatBot

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a closed‐loop optimization workflow integrating CatBot, an automated synthesis and testing system, to discover NiMo hydrogen‐evolution catalysts. CatBot synthesised and evaluated 228 unique samples, identifying the best performing catalysts for transfer to nickel‐foam electrodes. The best candidate is highly active, reaching 1 Acm−2${

MESH 3.1 – Layered Universe Theory

open access: yes
Özet MESH 3.1 – Katmanlı Evren Kuramı, evrensel çekimi eğrilik değil, iç içe geçmiş simetri katmanları arasında oluşan yapısal uyum olarak yorumlayan yeni bir kozmolojik modeldir. Kuark-gluon çekirdeği temeline dayanan bu öneri; felsefi düşünme, kuantum ilkeleri ve yanlışlanabilirliği birleştirerek hem bilimsel hem eğitsel bir yaklaşım sunar. Bağımsız

Amphoteric Cu‐Doping Leading to High Thermoelectric Performance in p‐Type Bismuth Antimony Telluride

open access: yesAdvanced Functional Materials, EarlyView.
This study shows that Cu plays two opposite roles in p‐type Bi0.5Sb1.5Te3 depending on the processing route. Under thermodynamic‐equilibrium bulk‐synthesis, Cu mainly occupies cation sites, increases hole concentration, preserves mobility, and slightly reduces lattice heat transport. The best‐performing composition among the investigated series reaches

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.

Characterization of vibration transmission paths for gearbox condition monitoring [PDF]

open access: yes, 2010
For gearbox condition monitoring, the position of the accelerometers can be crucial for the detection of possible defects. However, little information can be found in the literature for engineers in setting up condition monitoring.

Mesh refinement for parallel-adaptive FEM : theory and implementation

open access: yes, 2019
We investigate parallel adaptive grid refinement and focus in particular on hierarchically adaptive, parallel and conforming simplicial grids that use Newest Vertex Bisection (NVB) as their refinement strategy. One challenge of NVB is its applicability to arbitrary simplex grids, which is not possible with the current compatibility condition. We define
