Stochastic Frontier Models
The stochastic frontier model was first proposed in the context of production function estimation to account for the effect of technical inefficiency. The inefficiency causes actual output to fall below the po...

Simulation Studies of Two-Layer Hopfield Neural Networks for Automatic Wafer Defect Inspection
The occurrence of defect on a wafer may result in losing the yield ratio. The defective regions were usually identified through visual judgment with the aid of a scanning electron microscope. Dozens of people ...

Heteroscedasticity and Non-Monotonic Efficiency Effects of a Stochastic Frontier Model
We consider a model that provides flexible parameterizations of the exogenous influences on inefficiency. In particular, we demonstrate the model's unique property of accommodating non-monotonic efficiency eff...

One-Step and Two-Step Estimation of the Effects of Exogenous Variables on Technical Efficiency Levels
Consider a stochastic frontier model with one-sided inefficiency u, and suppose that the scale of u depends on some variables (firm characteristics) z. A “one-step” model specifies both the stochastic frontier an...

Novel Synthesis, Characterization, and Physical Properties of Self-Doped Sulfonated Polyaniline by Copolymerization between p-Aminodiphenylamine and o-Aminobenzenesulfonic Acid
Sulfonated polyaniline has been synthesized by a novel method, in which p-aminodiphenylamine (p-APA) and o-aminobenzenesulfonic acid (o-ABS) are copolymerized. The copolymers produced have the same composition ev...

Large Deviations for Large Capacity Loss Networks with Fixed Routing and Polyhedral Admission Sets
In this paper, we study large deviations of large capacity loss networks with fixed routing. We use two-level modelling for the loss networks: the call level and the cell level. At the call level, a call reque...
