Selection of the proper burner tile design and material requires knowing the operating temperature profile and thermal boundary conditions to ensure optimum performance.
The campfire restrictions are still in place across the Boundary Waters Canoe Area with six fires still burning in the area and continued dry conditions.
Improved hover performance in high and hot conditions for the Bell Huey and its derivatives is the promise of the FastFin tail-rotor enhancement and stability system from Boundary Layer Research (Booth No 2970) of Everett, Wash.
Citing the recent dry conditions as a markedly low rainfall recently, the burn ban enjoins individuals from burning within county boundaries.

In science:

It should be noted that these boundary conditions are written on the complex plane, while the boundary conditions in are written on the strip.
Worldsheet and Spacetime Properties of p-p' System with B Field and Noncommutative Geometry
The boundary condition we use is a radiative boundary condition applied to the difference between a given variable and its exact value: f − fexact = u(r − t)/r .
Simple excision of a black hole in 3+1 numerical relativity
To define it, we must generalize the untwisted stabilizer (26) to the central stabilizer Cλ : Cλ := {J ∈ Sλ | φλ(K, J ) = 1 for all K ∈ G ′} 9 This construction covers huge class of boundary conditions, but in general it does not exhaust the space of all conformal boundary conditions of a CFT.
Conformal field theory, boundary conditions and applications to string theory
In particular there exist boundary conditions without automorphism type; known examples include boundary conditions associated to conformal embeddings (for a review see [50, 23] and lectures by J.-B.
Conformal field theory, boundary conditions and applications to string theory
The small volume, originally with periodic boundary conditions, is then embedded with isolated boundary conditions in a new top grid field δ0 ( ~m ).
Multiscale Gaussian Random Fields for Cosmological Simulations
Boundary conditions To construct pure phases, as for Gibbs fields, it is useful to have the notion of finite Gibbs family with given boundary conditions.
Gibbs and Quantum Discrete Spaces
Boundary conditions (d-boundary conditions) are given by a sequence ν N ,d(γ ) of probability measures on the set of finite (not necessary connected) spin graphs γ , intuitively on N -annuli of width d.
Gibbs and Quantum Discrete Spaces
Also, it may be possible to extend some of the conclusions of this paper to measures with certain other boundary conditions, such as that generated with free boundary conditions and conditioned on D , but we shall not pursue this here.
Rigidity of the interface for percolation and random-cluster models
We will see that toroidal (continuous) boundary conditions make a vital difference compared to having open boundary conditions.
Random Geometric Graphs
To determine an effective slip/stick length, one has to solve an appropriate hydrodynamic problem with a boundary condition on a random rough wall and to compare the results with those for a similar problem with a slip boundary condition on a smooth wall.
Surface Roughness and Effective Stick-Slip Motion
Also, small changes in the model rules (like replacing open boundary conditions with periodic boundary conditions , or introducing frozen noise ), destroy the SOC behavior.
The complex scaling behavior of non--conserved self--organized critical systems
Let us first discuss the case of periodic boundary conditions, which will be relevant also for the later discussion of the system with open boundary conditions.
The complex scaling behavior of non--conserved self--organized critical systems
Again, the different thresholds depend on the boundary conditions, but the qualitative behaviour described are robust to changes in the types of boundary conditions.

McCoy and Wu give the partition function for a system with non-helical boundary conditions, whereas we have used helical boundary conditions.

Hence, when φ = 0 the resulting free fermions problem must have anti-periodic boundary conditions if the number of fermions is even and periodic boundary conditions if N is odd .
