Contact Processes
, 2015
"... A onedimensional contact process is a continuoustime Markov process on the lattice Z of integers. The state at time is given by a set ⊆ Z of the lattice sites which we visualize as being occupied by particles. The system evolves as follows: • if ∈ , then becomes vacant at rate 1 • if ∈ , ..."

A onedimensional contact process is a continuoustime Markov process on the lattice Z of integers. The state at time is given by a set ⊆ Z of the lattice sites which we visualize as being occupied by particles. The system evolves as follows: • if ∈ , then becomes vacant at rate 1
The Contact Process with Added Edges
, 2004
"... We show that the critical value for the contact process on a vertextransitive graph G with finitely many edges added to it is the same as the critical value for the contact process on G. This gives a partial answer to a conjecture of Pemantle and Stacey. ..."

CONTACT PROCESSING IN THE SIMULATION OF CLAWAR
"... Contact processing, including collision detection and collision response, is one of the most difficult, but most important areas in simulation of the multibody systems. However, the most widespread multibody simulators, like Matlab/SimMechanics or Modelica/Dymola, don’t support the contact process ..."

Statistics for the contact process
 Statistica Neerlandica
, 2002
"... A ddimensional contact process is a simplified model for the spread of an infection on the lattice Zd. At any given time tP0, certain sites x 2 Zd are infected while the remaining once are healthy. Infected sites recover at constant rate 1, while healthy sites are infected at a rate proportional to ..."

"... We introduce a continuous version of the contact model which is wellknown and widely studied in the lattice case. Under certain general assumptions on the infection spreading characteristics we construct the contact process as a Markov process in the configuration space of the system. ..."

The contact process on trees
 Ann. Probab
, 1992
"... The contact process on an infinite homogeneous tree is shown to exhibit at least two phase transitions as the infection parameter λ is varied. For small values of λ a single infection eventually dies out. For larger λ the infection lives forever with positive probability but eventually leaves any fi ..."

Contact process in a wedge
, 2010
"... We prove that the supercritical onedimensional contact process survives in certain wedgelike spacetime regions, and that when it survives it couples with the unrestricted contact process started from its upper invariant measure. As an application we show that a type of weak coexistence is possibl ..."

Qualitative process theory
 MIT AI Lab Memo
, 1982
"... Objects move, collide, flow, bend, heat up, cool down, stretch, compress. and boil. These and other things that cause changes in objects over time are intuitively characterized as processes. To understand commonsense physical reasoning and make programs that interact with the physical world as well ..."

Cluster approximation for the contact process
 J. Phys. A
, 1994
"... The onedimensional contact process is analyzed by a cluster approximation. In this approach, the hierarchy of rate equations for the densities of finite length empty intervals are truncated under the assumption that adjacent intervals are not correlated. This assumption yields a first order phase t ..."

The Contact Process with Fast Voting
, 2013
"... Consider a combination of the contact process and the voter model in which births occur at rate λ, deaths at rate 1, and voting events occur at rate θ between a site and each of its neighbors. We are interested in the asymptotics for the critical value as θ → ∞. In d ≥ 3, λc(θ) → 1/ρd where ρd is t ..."
