Splash singularities for the one-phase Muskat problem in stable regimes

, 2015
This paper shows finite time singularity formation for the Muskat problem in a stable regime. The framework we found is with a dry region, where the density and the viscosity are set equal to $0$ (the gradient of the pressure is equal to $(0,0)$) in the ...

Data‐Driven Design of Co‐Continuous Morphology in PS/PMMA Two‐Phase Polymer Blends: A Theoretical, Experimental, and Machine Learning Approach

Polymer Engineering &Science, EarlyView.
This study uses an integrated methodology for polymer blend design and development. It uses theoretical and experimental techniques to evaluate phase inversion and employs a novel computational tool to determine the highest co‐continuity degree using machine learning.

Structural characterization and optimum machining parameters of jute/carbon fibre hybrid reinforced epoxy composite laminates

Polymer International, EarlyView.
Hybrid jute/carbon epoxy laminates have better mechanical performance and less drilling damage by the use of optimized stacking sequence and machining parameters. Abstract Three composite laminate systems were produced using the standard hand lay‐up method: jute‐fibre‐reinforced polymer (JFRP), carbon‐fibre‐reinforced polymer (CFRP) and a hybrid of the

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Study on the Oil Distribution and Churning Loss in the Rotation of a Planetary Gear Train

Jixie chuandong
A splash lubrication simulation model of a planetary gear train was established based on the moving particle semi-implicit （MPS） method, and it was verified by experiments to explore the splash lubrication behavior of the planetary transmission.

Design and lubrication of high-speed rolling-element bearings [PDF]

The speed capability of rolling element bearings has increased from speeds of less than two million DN to speeds of three million DN. The life and reliability of these bearings also increased where they are equal to, or greater than, those of bearings ...

The Age and Origin of Block Deposits in the Victorian Alps, Australia

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in
