Directed random graphs with given degree distributions

open access: yesStochastic Systems, 2013
Given two distributions F and G on the nonnegative integers wepropose an algorithm to construct in- and out-degree sequences fromsamples of i.i.d. observations from F and G, respectively, thatwith high probability will be graphical, that is, from which a

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

open access: yesAdvanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Optimal paths in large deviations of symmetric reflected Brownian motion in the octant

open access: yesStochastic Systems, 2013
We study the variational problem that arises from considerationof large deviations for semimartingale reflected Brownian motion (SRBM) in $mathbb{R}^3_+$.

A skill based parallel service system under FCFS-ALIS ‒ steady state, overloads and abandonments

open access: yesStochastic Systems, 2014
We consider a queueing system with servers S={m1,...,mJ}, and with customer types C={a,b,...}. A bipartite graph G describes which pairs of server-customer types are compatible.

Multilayer Self‐Limiting Electrospray Deposition via Stepped Voltage Bias

open access: yesAdvanced Engineering Materials, EarlyView.
Self‐limiting electrospray deposition (SLED) uses a high voltage to generate and deposit a charged payload on a target surface. The coating retains its charge, repelling newly arriving material. SLED thickness can be decreased by applying a secondary bias to the target.

Nearly periodic behavior in the overloaded G/D/s+GI queue

open access: yesStochastic Systems, 2011
Under general conditions, the number of customers in a GI/D/s+GI many-server queue at time t converges to a unique stationary distribution as t → ∞. However, simulations show that the sample paths routinely exhibit nearly periodic behavior over long time

The morphing of fluid queues into Markov-modulated Brownian motion

open access: yesStochastic Systems, 2015
Ramaswami showed recently that standard Brownian motion arises as the limit of a family of Markov-modulated linear fluid processes.We pursue this analysis with a fluid approximation for Markov-modulated Brownian motion.
