Aggregation and Stability in Metapopulation Models
The American Naturalist, 1992We analyze a metapopulation model of the interactions between Lotka-Volterra-type prey and predators that occur in two environmentally distinguishable patches and are linked by migration. Environmental differences between the patches tend to stabilize the otherwise neutrally stable model by causing the per capita immigration rate on a patch to be ...

Stability in Aggregation Operators
2012Aggregation functions have been widely studied in literature. Nevertheless, few efforts have been dedicated to analyze those properties related with the family of operators in a global way. In this work, we analyze the stability in a family of aggregation operators The stability property for a family of aggregation operators tries to force a family to ...

Stability of aggregate computing
2020Open cyber-physical systems like smart cities, tactical information sharing, personal and home area networks, and the Internet of Things (IoT) require seam- less, low latency, peer to peer local interactions between devices. Their potential is curtailed by the fact that devices currently interact either through device and application specific protocols

Aggregate Stability and Size Distribution [PDF]
Soil Science Society of America Book Series, 1986 An aggregate is a group of primary particles that cohere to each other more strongly than to other surrounding soil particles. Most adjacent particles adhere to some degree.

Aggregation and Aggregate Stability in Forest and Range Soils
Soil Science Society of America Journal, 1988Abstract A simple method for measuring aggregation and aggregate stability across soils of widely varying structure and texture is presented. The method uses standard techniques of particle‐size analysis to measure yield of fine particles (<26‐µm estimated spherical diam.) after three types of dispersion treatments: shaking in ...

Stability of Some Mechanisms of Chemotactic Aggregation
SIAM Journal on Applied Mathematics, 2002In this paper, the stability of a blow-up mechanism for a particular Keller--Segel model that yields chemotactic aggregation is considered. It is shown using matched asymptotic methods that the considered blow-up mechanism is stable. More precisely, small perturbations of the initial data produce a small shifting on the blow-up time and the blow-up ...

GLOBAL STABILITY OF NASH EQUILIBRIUM IN AGGREGATIVE GAMES [PDF]
International Game Theory Review, 2014 If an aggregative game satisfies the generalized Hahn conditions, then there exists a unique Nash equilibrium which may not be interior and is globally asymptotically stable under two alternative continuous adjustment processes with non-negativity constraints.

Gravity as a factor of aggregative stability and coagulation
Advances in Colloid and Interface Science, 2007Gravity is a potential factor of aggregative stability and/or coagulation for any heterogeneous system having a density contrast between the dispersed phase and its dispersion medium. However, gravity becomes comparable to other stability factors only when the particle size becomes large enough.

Chemical and Physical Stability of Microbially Stabilized Aggregates
Soil Science Society of America Journal, 1971Abstract Chemical properties of microbially bound aggregates were determined by organic solvent extraction and by the rate of sonic dispersion of the aggregates. Seven fungi, six streptomycetes, and four bacteria, produced in situ chemically different binding agents which ...
