Relation of vertebral deformities to bone density, structure, and strength. [PDF]

, 2010
Because they are not reliably discriminated by areal bone mineral density (aBMD) measurements, it is unclear whether minimal vertebral deformities represent early osteoporotic fractures.

Response surfaces for compressive strength of concrete

Construction and Building Materials, 2013
The aim of total quality management (TQM) is to offer satisfactorily high quality products to customers for providing increased productivity and decreased costs. Various methods are used for process improvement, development and optimization. In ready mixed concrete production, the number and the variations of effect parameters can be reduced using ...

Magnetic Field Strength in the Upper Solar Corona Using White-light Shock Structures Surrounding Coronal Mass Ejections [PDF]

, 2011
To measure the magnetic field strength in the solar corona, we examined 10 fast (> 1000 km/s) limb CMEs which show clear shock structures in SOHO/LASCO images. By applying piston-shock relationship to the observed CME's standoff distance and electron density compression ratio, we estimated the Mach number, Alfven speed, and magnetic field strength in ...

Simulation computation in grammar-compressed graphs [PDF]

arXiv, 2020
Like [1], we present an algorithm to compute the simulation of a query pattern in a graph of labeled nodes and unlabeled edges. However, our algorithm works on a compressed graph grammar, instead of on the original graph. The speed-up of our algorithm compared to the algorithm in [1] grows with the size of the graph and with the compression strength.

Effect of Granule Strength on Compressed Tablet Strength.

Chemical and Pharmaceutical Bulletin, 1995
The effect of granule strength on the strength of a tablet compressed under a certain force was examined. Crushing strength and diametral compression tests were carried out to assess granule and tablet strength, respectively. When granules were weak, tablet strength increased with granule strength.
