A review of physics-based models in prognostics: application to gears and bearings of rotating machinery [PDF]

open access: yes, 2016
Health condition monitoring for rotating machinery has been developed for many years due to its potential to reduce the cost of the maintenance operations and increase availability.

Hydraulic fracturing in cells and tissues: fracking meets cell biology [PDF]

open access: yes, 2017
The animal body is fundamentally made of water. A small fraction of this water is freely flowing in blood and lymph, but most of it is trapped in hydrogels such as the extracellular matrix (ECM), the cytoskeleton, and chromatin.

Bioengineering models of cell signaling [PDF]

open access: yes, 2000
Strategies for rationally manipulating cell behavior in cell-based technologies and molecular therapeutics and understanding effects of environmental agents on physiological systems may be derived from a mechanistic understanding of underlying signaling ...

Effect of Low-magnitude, High-frequency Vibration on Osteocytes in the Regulation of Osteoclasts [PDF]

open access: yes, 2010
Osteocytes are well evidenced to be the major mechanosensor in bone, responsible for sending signals to the effector cells (osteoblasts and osteoclasts) that carry out bone formation and resorption. Consistent with this hypothesis, it has been shown that

Warranty Data Analysis: A Review [PDF]

open access: yes, 2012
Warranty claims and supplementary data contain useful information about product quality and reliability. Analysing such data can therefore be of benefit to manufacturers in identifying early warnings of abnormalities in their products, providing useful ...

Prospects of microalgal biodiesel production in Pakistan – a review [PDF]

open access: yes, 2017
Biodiesel is an alternative, renewable, biodegradable and environmentally friendly fuel for transportation, with properties like petroleum-derived diesel, and can be used directly in a compression ignition engine without any modifications.

A survey of outlier detection methodologies [PDF]

open access: yes, 2004
Outlier detection has been used for centuries to detect and, where appropriate, remove anomalous observations from data. Outliers arise due to mechanical faults, changes in system behaviour, fraudulent behaviour, human error, instrument error or simply ...

An experimental and computational analysis of buoyancy driven flows by laser sheet tomography, particle image velocimetry and computational fluid dynamics [PDF]

open access: yes, 1997
This paper contains details of a three pronged investigation into the development of a buoyant jet impinging on a wall in a closed vessel. The development of the flow was measured experimentally by particle image velocimetry (PIV) and laser sheet ...

Model predictions and experimental results for the rotordynamic characteristics of leakage flows in centrifugal pumps [PDF]

open access: yes, 1993
The role played by fluid forces in determining the rotordynamic stability and characteristics of a centrifugal pump is gaining increasing attention. The present research investigates the contributions to the rotordynamic forces from the discharge-to ...
