Percolation theory and physics of compression

European Journal of Pharmaceutics and Biopharmaceutics, 1997
Abstract The concept of percolation theory is an excellent tool to elucidate the physics of compression. Earlier findings taking into account the percolation theory indicated that the formation of a tablet can be subdivided into a two-stage process with a ‘weak-bond’ percolation effect at a lower percolation threshold pc corresponding to the relative

Extreme data compression while searching for new physics [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
Bringing a high-dimensional dataset into science-ready shape is a formidable challenge that often necessitates data compression. Compression has accordingly become a key consideration for contemporary cosmology, affecting public data releases, and ...

Compression at the Physical Interface

IEEE Signal Processing Magazine, 2008
This article focuses on recent progress in physical compressive sampling under the Defense Advanced Research Agency's Analog-to-Information (A-to-I) and Multiple Optical Non-Redundant Aperture Generalized Sensors (MONTAGE) programs. A-to-I and MONTAGE focus on aggressive forms of generalized sampling under which measurements consist of transformations,

Advancing test compression to the physical dimension

2017 IEEE International Test Conference (ITC), 2017
Test Compression ratios are currently stalled at 100–200X. A new 2-dimensional physically-aware sequential Compressor-Decompressor design addresses the severe wiring congestion as well as the test coverage droop and pattern spike at the highest compression ratios. Results on some commonly used industrial designs shows a 2X reduction in routing overhead

Compression Physics in the Formulation Development of Tablets

Critical Reviews™ in Therapeutic Drug Carrier Systems, 2006
The advantages of high-precision dosing, manufacturing efficiency, and patient compliance make tablets the most popular dosage forms. Compaction, an essential manufacturing step in the manufacture of tablets, includes compression (i.e., volume reduction and particle rearrangement), and consolidation (i.e., interparticulate bond formation).

Effect of Physical Properties on Compression Characteristics

Journal of Pharmaceutical Sciences, 1975
The tranmission of force to the die wall was measured by a piezoelectric sensor, and the compression cycles of lactose granules of different shapes were compared. In addition, a nearly spherical fraction of spray-dried lactose was similarly compared with a crystalline sample.

The Physics of Tablet Compression. II. The Influence of Degree of Compression on Properties of Table†‡

Journal of the American Pharmaceutical Association (Scientific ed.), 1953
A study has been made of the influence of compressional force employed in tablet compression on the apparent density, porosity, hardness, disintegration time, and average primary particle size of compressed tablets, The data obtained for the sulfathiazole granulations studied indicate that there is a logarithmic relationship between the compressional ...
