Snow densification during rain
Observations and measurements indicate rain often has a major impact on snow slope stability. Measurements to investigate the effects of wetting of low density, alpine snow were made at Snoqualmie Pass, WA, USA. Results indicate that on first wetting, the densification rate can increase by three orders of magnitude. This initial burst of densification occurs independently of the gravitational l...
متن کاملGraphs Over Time: Densification and Shrinking Diameters
How do real graphs evolve over time? What are “normal” growth patterns in social, technological, and information networks? Many studies have discovered patterns in static graphs, identifying properties in a single snapshot of a large network, or in a very small number of snapshots; these include heavy tails for inand out-degree distributions, communities, small-world phenomena, and others. Howe...
متن کاملImproved Densification of One Permutation Hashing
The existing work on densification of one permutation hashing [24] reduces the query processing cost of the (K,L)-parameterized Locality Sensitive Hashing (LSH) algorithm with minwise hashing, from O(dKL) to merely O(d + KL), where d is the number of nonzeros of the data vector, K is the number of hashes in each hash table, and L is the number of hash tables. While that is a substantial improve...
متن کاملTwo-phase densification of cohesive granular aggregates.
When poured into a container, cohesive granular materials form low-density, open granular aggregates. If pressure is applied to these aggregates, they densify by particle rearrangement. Here we introduce experimental and computational results suggesting that densification by particle rearrangement occurs in the form of a phase transition between two configurational phases of the aggregate. Then...
متن کاملHigh-Pressure Densification of Composite Lunar Cement
In order to minimize the binder content in composite lunar “cement,” this paper uses JSC-1A lunar soil simulant and unsaturated polyester resin (UPR) to produce low-binder-content composite. Important system parameters such as compression pressure, compression duration, vibration, loading rate, loading number, and initial grain size distribution are analyzed. The most critical control variable ...
