Parallel software auto-tuning using statistical modeling and machine learning

open access: yes, 2018
Auto-tuning for complex and nontrivial parallel systems is usually time-consuming because of empirical evaluation of huge amount of combinations of parameter values of an initial parallel program in a target execution environment. This paper proposes the

Morphology-Tuning-Induced Highly Efficient Regeneration of Pt/C Nanoelectrocatalysts

open access: yes, 2017
The sintering-induced irreversible deactivation of precious metal nanocatalysts is one of the main obstacles for their sustainable application. Here, by adding fluorine (F)-doped carbon support to improve the redispersion and tune the morphology of ...

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

open access: yesAdvanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Multimodal Data‐Driven Microstructure Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures

open access: yesAdvanced Engineering Materials, EarlyView.
We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Demo 10-03 Tuning Forks

open access: yes, 2001
Three tuning forks of frequencies 256, 512, and 1024 Hz (at octave frequency intervals) are sounded and their waves displayed on an oscilloscope. The wave produced by a tuning fork is sinusoidal, as can be heard on the video and illustrated in Figure ...
