Look Closely: Lessons Prof. Gérard T. Simon Might Have Taught

This symposium honors Prof. Gérard T. Simon, a respected colleague in the field of ultrastructural pathology. Though he distinguished himself during the several decades of his career as an outstanding diagnostician, laboratorian, and investigator, he is perhaps best known as an educator and evangelist for the importance of electron microscopy, particularly for trainees. It is no surprise that t...

A Markov model for measuring service levels in nonstationary G(t)/G(t)/s(t) +G(t) queues

We present a Markov model to approximate the queueing behavior at the G(t)/G(t)/s(t) + G(t) queue with exhaustive discipline and abandonments. The performance measures of interest are: (1) the average number of customers in queue, (2) the variance of the number of customers in queue, (3) the average number of abandonments and (4) the virtual waiting time distribution of a customer when arriving...

We study the notion of a stub equality for a congruence generated by a ground term rewrite system (GTRS). We study the congruence generated by the union of GTRSs R and S , where the congruences generated by R and S intersect with respect to their stubs. We show that for any equivalent reduced GTRSs R and S , the same number of terms appear as subterms in R as in S . We give an upper bound on th...
