Through the study of forest-pulp enterprise production logistics pulping flow sub-system and production elixir flow sub-system, Petri nets model and the object-oriented model as the theoretical basis, and puts forward the enterprise production logistics subsystem compound model, and discusses the pulping process based on the composite model of logistics balance mathematical principle.

Static Single Assignment Form benefits data flow analysis by its static guarantees on the definitions and uses of variables. In this paper, we show how to exploit these guarantees to enable a sparse data flow analysis of variable predicates, for gaining a rich predicate-based and path-oriented characterization of a program’s variables’ values.

Autonomous navigation of a flying vehicle in a cluttered environment has been simulated to demonstrate novel yet simple techniques for avoiding obstacles using optic flow and image loom signals whilst successfully navigating a vehicle towards a goal. The simulation makes use of simulated flow fields calculated on cameras looking downwards, forwards, rearwards and sidewards. This computation cou...

We perform a numerical study of a knotted flow through a cylinder. In this example – which is due to Conley [1] – based on certain assumptions on the flow Wazewski’s Theorem guarantees the existence of an unstable invariant set inside the cylinder. We explicitly construct a flow with the desired properties and approximate the corresponding invariant set using set oriented multilevel subdivision...

Abstract Optical flow provides an opportunity to elevate the resolution and sensitivity of deflection sensing in background-oriented schlieren (BOS). Despite extensive relevant literature within field computer vision, there is a lack proper quantification its abilities limitations with regard state-of-the-art BOS experiments. Thus, this study performs assessment accuracy limits different scenar...

We demonstrate a method by which we can produce an oriented film of an inverse bicontinuous cubic phase (Q(II)(D)) formed by the lipid monoolein (MO). By starting with the lipid as a disordered precursor (the L(3) phase) in the presence of butanediol, we can obtain a film of the Q(II)(D) phase showing a high degree of in-plane orientation by controlled dilution of the sample under shear within ...
