Automaton Semigroups: The Two-state Case

A generalized semi-Markov process with speeds describes the fluctuation, in time, of the state of a certain general system involving, at any given time, one or more living components, whose residual lifetimes are being reduced at state-dependent speeds. Conditions are given for the stationary state distribution, when it exists, to depend only on the means of some of the lifetime distributions, not their exact shapes. This generalizes results of König and Jansen, particularly to the infinite-state case.

State Case

This article examines precursors to leadership practice, specifically through the lens of role identity. The assumption explored is that people are unlikely to engage in the hard work of leadership if they do not see that challenge as part of who they are and what they do, especially collaborative or system-level leadership. Role identity is, then, a critical building block in developing a deeper understanding of leadership intentions and actions especially in collaborative settings. Multiple judicial players, termed here “public service lawyers,” are investigated in this single-state case study that examines individuals’ view of their role and primary focus. Factors are examined that contribute to the construction of role perception. Results reveal that leadership training, the position one holds, and motivational orientation all influence the extent to which public service lawyers develop a view of their role that includes a broader system or collaborative orientation.

State Case

Three flare systems are modeled and total plant depressurization is investigated using dynamic simulations in order to access the debottlenecking potential. Usually steady-state simulation of the flare network is used for sizing and rating of the flare system. By using dynamic simulations effects from line packing in the flare system can be studied. The results show that peak flow during a dynamic simulations is significantly lower than the peak flow used in a steady-state case. <br>The three systems investigated span a wide range in flare system size, both in terms of number of process segments disposing into the flare network, in terms of peak design rate and the flare network pipe dimensions and total hold-up volume. Generally, it is observed that the larger the flare system, the larger debottlenecking potential.
