Minuteman load – A special load that allows the firefighters to pull a large section of the hose onto their shoulders and have it drop off (called "paying out") in an organized fashion as they advance towards the fire. [8] "S" load, more commonly known as the "triple-layer" load – The hose is folded three times before being loaded.
Triple lay ("triple fold", "triple load") A method of loading preconnected attack line into a hose bed or crosslay, often facilitating rapid hose deployment in a pre-flaked configuration. Turnout gear The protective clothing worn by firefighters, made of a fire-resistant material such as Nomex or Aramid, and designed to shield against extreme heat.
In graph theory and theoretical computer science, the longest path problem is the problem of finding a simple path of maximum length in a given graph.A path is called simple if it does not have any repeated vertices; the length of a path may either be measured by its number of edges, or (in weighted graphs) by the sum of the weights of its edges.
Here, the bar on the left side of the figure is the mixing length. In fluid dynamics, the mixing length model is a method attempting to describe momentum transfer by turbulence Reynolds stresses within a Newtonian fluid boundary layer by means of an eddy viscosity. The model was developed by Ludwig Prandtl in the early 20th century. [1]
Triple deck theory is a theory that describes a three-layered boundary-layer structure when sufficiently large disturbances are present in the boundary layer. This theory is able to successfully explain the phenomenon of boundary layer separation, but it has found applications in many other flow setups as well, [1] including the scaling of the lower-branch instability of the Blasius flow, [2 ...
A common linearization of this problem is the minimization of the maximum utilization , where ∀ ( u , v ) ∈ E : U m a x ≥ U ( u , v ) {\displaystyle \forall (u,v)\in E:\,U_{max}\geq U(u,v)} In the minimum cost multi-commodity flow problem , there is a cost a ( u , v ) ⋅ f ( u , v ) {\displaystyle a(u,v)\cdot f(u,v)} for sending a flow ...
[1] [3] The Coffman–Graham algorithm may be used to find a layering with a predetermined limit on the number of vertices per layer and approximately minimizing the number of layers subject to that constraint. [1] [2] [3] Minimizing the width of the widest layer is NP-hard but may be solved by branch-and-cut or approximated heuristically. [3]
The maximum flow problem can be seen as a special case of more complex network flow problems, such as the circulation problem. The maximum value of an s-t flow (i.e., flow from source s to sink t) is equal to the minimum capacity of an s-t cut (i.e., cut severing s from t) in the network, as stated in the max-flow min-cut theorem.
