In this paper, the authors' consider a continuous-review inventory model for a retailer who faces constant, deterministic demand but whose supplier is unreliable. The supplier experiences "wet" and "dry" operational and disrupted periods whose durations are exponentially distributed. The retailer follows an EOQ-like policy during wet periods but may not...
This paper presents results of a pursuit of a repeatable and objective methodology of analysis of the electroencephalographic EEG time series. Adaptive time-frequency approximations of EEG are discussed in the light of the available experimental and theoretical evidence, and applicability in various experimental and clinical setups. Four lemmas and three...
Sparse approximations to Bayesian inference for nonparametric Gaussian Process models scale linearly in the number of training points, allowing for the application of these powerful kernel-based models to large datasets. We show how to generalize the binary classification informative vector machine IVM to multiple classes. In contrast to earlier efficient...
In this paper, one proposes a new approximate approach for analyzing queuing models of single stage kanban systems. The approach is based on parametric decomposition technique and two moment approximations. The main building block of approach is a new two-moment approximation characterizing the performance of fork/join stations fed by general...
Bounds and approximate formulas are developed for the average optimum distance of the transportation linear programming problem TLP with homogeneously but randomly distributed points and demands in a region of arbitrary shape. The paper discusses how its results were used to estimate costs under uncertainty for a vehicle-repositioning problem. This...
The purpose of this technical paper is to present a methodology that has been used to show that, based on the NB-3200 definitions; the Piping Elbow C2 stress index can be smaller than the C2 stress index currently defined in the ASME-Code. The revised C2 stress index is derived through...
This paper describes some stochastic control problems in financial engineering arising from the need to find investment strategies to optimize some goal. Typically, these problems are characterized by nonlinear Hamilton-Jacobi-Bellman partial differential equations, and often they can be reduced to linear PDEs with the Legendre transform of convex duality. This...
This paper presents a simple and precise analytical approximation method for pricing American options under Merton’s assumptions. It is a generalization of the approximations of the Partial Differential Equation PDE developed by McMillan, and Barone-Adesi and Whaley. The proposed solution is compared to other approximations, including the Cox, Ross and...

Evaluating the reliability of a transportation network often involves an intensive simulation exercise to randomly generate and evaluate different possible network states. This paper proposes an algorithm to approximate the network reliability which minimizes the use of such simulation procedure. The algorithm will dissect and classify the network states into...
This study performs a theoretical analysis of instability in a departure time choice problem. Stability of equilibrium is an important factor for reliability of travel time. If equilibrium is not stable, travel time changes over a period of days even if demand and network performance are stable. This study examines...
At approximately 6:10 a.m., USS John S. McCain's bridge watch team observed a fire on a ship on the horizon and, in response, maneuvered towards the burning vessel. Upon observing a life raft with 11 people on board drifting in the vicinity of the burning ship, crew members immediately launched...
Australian Reconstruction Task Force RTF soldiers in southern Afghanistan have fought off a number of Taliban attacks on a new construction project over the last few days of February, 2008. The attacks occurred approximately 15km from Tarin Kowt, where RTF engineers are helping to construct a patrol base...
