Arc Segmentation in Linear Time
, 2011 A linear algorithm based on a discrete geometry approach is proposed for the detection of digital arcs and digital circles using a new representation of them. It is introduced by inspiring from the work of Latecki [1]. By utilizing this representation, we transform the problem of digital arc detection into a problem of digital straight line recognition.

Soundness of Timed-Arc Workflow Nets in Discrete and Continuous-Time Semantics [PDF]
Fundamenta Informaticae, 2015 Analysis of workflow processes with quantitative aspects like timing is of interest in numerous time-critical applications. We suggest a workflow model based on timed-arc Petri nets and study the foundational problems of soundness and strong (time-bounded) soundness.

Decidability of Properties of Timed-Arc Petri Nets [PDF]
, 2000 Timed-arc Petri nets (TAPN’s) are not Turing powerful, because, in particular, they cannot simulate a counter with zero testing. Thus, we could think that this model does not increase significantly the expressiveness of untimed Petri nets. But this is not true; in a previous paper we have shown that the differences between them are big enough to make ...

Time constants for nonstationary arcs [PDF]
Zeitschrift für Physik A Hadrons and nuclei, 1968 The time constants associated with the initial deviations of an arc column from a static state have been studied analytically. The basic approach is to use a Taylor series expansion in powers of time of the energy balance equation. It is assumed that the arc gas is optically thin and is in local thermal equilibrium.
