Complexity theory suggests that we see performance as an emergent property, the result of complex interactions and relationships. This can clash, however, with what stakeholders see as legitimate and normal in accident investigations. When systems fail, it is still common to blame components (e.g. human errors) and when they succeed spectacularly, to think in terms of individual heroism (e.g. t...

We suggest a rigorous definition of the pathwise flux across the boundary of a bounded open set for transient finite energy diffusion processes. The expectation of such a flux has the property of depending only on the current velocity v, the nonsymmetric (with respect to time reversibility) part of the drift. In the case where the diffusion has a limiting velocity we define the asymptotic flux ...

Solid-liquid thermo-reversibility, lacking in raw starch is an important property for gels allowing repeated thermal processing food. In this work, the Thermoproteus uzoniensis 4-α-glucanotransferase (TuαGT) was used to modify five different starches from potato, corn, rice, wheat, and pea thermo-reversibility of modified evaluated by rheological assay. Only potato (MPS) exhibited which prompte...

Many practical and important systemic properties of manufacturing systems, like deadlock freeness, liveness, and reversibility, can be formulated as the non-blocking property of discrete-event systems. It can be difficult, however, to verify non-blocking or design a supervisor to guarantee non-blocking control because of state size explosion in the concurrency model. In this paper, we present s...

As a generalization of the 2D Fourier transform (2D FT) and 2D fractional Fourier transform, the 2D nonseparable linear canonical transform (2D NsLCT) is useful in optics and signal and image processing. To reduce the digital implementation complexity of the 2D NsLCT, some previous works decomposed the 2D NsLCT into several low-complexity operations, including 2D FT, 2D chirp multiplication (2D...

Imprinting of cholesteric textures in a polymer network is a method of preserving a macroscopically chiral phase in a system with no molecular chirality. By modifying the elastic properties of the network, the resulting stored helical twist can be manipulated within a wide range since the imprinting efficiency depends on the balance between the elastic constants and twisting power at network fo...

As a physiochemical property, asphaltenes are known to be one the most surface active compounds in crude oil. Due to such property, their behavior is most probably influenced by fluid-fluid interactions at the contact surface (interface). Potentially and naturally, in most cases, water is in contact with crude oil and is co-produced with it as well. Considering that asphaltene molecules are pol...

Reversibility is a suucient but not necessary condition for Markov chains for use in Markov chain Monte Carlo simulation. It is necessary to select a Markov chain that has a pre-speciied distribution as its unique stationary distribution. There are many Markov chains that have such property. We give guidelines on how to rank them based on the asymptotic variance of the estimates they produce. T...

The numerical integration in time of the equations of motion for mechanical systems subject to holonomic constraints is considered. Schemes are introduced for the direct treatment of a differential–algebraic form of the equations that preserve the constraints, the total energy, and other integrals such as linear and angular momentum arising from affine symmetries. Moreover, the schemes can be s...

In this paper, two tools to improve the performance of the NEHbased heuristics for the flow shop problem with and without buffer constraints are proposed. The first tool is the use of the reversibility property of the problems considered and the second one is a new tie-breaking strategy to be use in the insertion phase of the NEH heuristic. In addition, we have analyzed the behavior of five ini...
