This paper presents a Bonferroni procedure for selecting the alternative with the largest mean when the variances are unknown and unequal and correlation is induced among the observations for each alternative by common random numbers. Simulation results show that the Bonferroni procedure is more efficient than Dudewicz and Dalal's procedure when the(More)
which implement his algorithm in detail. Our approach departs from Nutt's in its basis in discrete-event simulation. As in sequential simulation there are cases where discrete-event approaches are preferable to time driven simulations and there are cases where the reverse is true. The running time of the distributed algorithm depends upon the model being(More)
A two-dimensional (2D) finite element analysis has been used in this study to model the insertion of the Nucleus electrode array with different stiffness properties in order to evaluate the propensity of damage by visualizing the predicted trajectories and by comparing the buckling stresses and the contact pressures at the tip (and its distribution along(More)
Analyses of water samples collected from the Mississippi River at Baton Rouge, Louisiana, during 1991-1997 indicate that hundreds of metric tons of herbicides and herbicide metabolites are being discharged annually to the Gulf of Mexico. Atrazine, metolachlor, and the ethane-sulfonic acid metabolite of alachlor (alachlor ESA) were the most frequently(More)
Trauma and damage during insertion of electrode arrays into the human cochlea are strongly related to the stiffness of the array. The stiffness properties of electrode arrays, which were determined by three-point flexural bending and buckling tests, are reported in this paper. To date there has been limited publication on mechanical properties of these(More)
This tutorial introduces manufacturing applications of simulation through three illustrative example applications. These examples illustrate the additional understanding of system behavior gained by the use of simulation models. Individuals using simulation should use a structured process in applying simulation. The second example illustrates this(More)
Previous experimental studies of insertion of the Nucleus standard straight and the Contour arrays into the scala tympani have reported that the electrode arrays cause damage to various cochlear structures. However, the level of insertion-induced damage by these electrode arrays to cochlear structures (the spiral ligament, the basilar membrane and the(More)
This paper presents a data-driven simulation of a network using manufacturing blocking to control work-in-process, and this simulation is called BNS for Blocking Network Simulation. The model is object oriented and is constructed in C++ using an object-oriented simulation environment called HOSE. The structure of the datadriven network simulator is(More)
This paper describes approximations for nonstationary queueing models. Explicit consideration of the time-dependent vector of probabilities associated with complex queueing systems requires numerical integration of the Chapman-Kolmogorov differential difference equations. The number of differential equations increases nonlinearly as the complexity of the(More)
