Characterization for imperfect polarizers under imperfect conditions
Applied Optics, 1998The principles for measuring the extinction ratio and transmittance of a polarizer are formulated by use of the principal Mueller matrix, which includes both polarization and depolarization. The extinction ratio is about half of the depolarization, and the contrast is the inverse of the extinction ratio.

Imperfect People in an Imperfect World
1991In an ideal world people would not be hurtful to each other and we would all work together to create the happiness we each yearn for. While this is the kind of world we are striving for, we still have a long way to go. We are imperfect, and we need to deal with ourselves and with each other with that in mind.

Essays on Imperfect Humans and Imperfect Algorithms
2022The most useful work in behavioral economics documents costly mistakes that people make in important settings and identifies ways to help them make better decisions. This dissertation presents four articles with those two goals in mind. In chapter one, co-authored with Yuji Winet, I examine perverse motivations people have in jury decisions and group ...

Imperfect vaccines and imperfect models
Trends in Ecology & Evolution, 2002Abstract A recent paper by Gandon et al. presents a model for how leaky vaccines can lead to evolutionary changes in the virulence of parasites. Whilst readers of some of the press reaction to this paper might be forgiven for thinking that it referred to certainties about actual malaria vaccines, there are currently no malaria vaccines beyond the ...

Tall, young, slim, bright, sporty, polite, athletic, controlled, musical, socially polished, good looking, sensible, and obedient, with straight white teeth: these traits of perfection are the aspirations of many parents and adults alike. And medicine is a candle to the perfect and perfectionism—a perfect degree, status, job, and career.

Operations Research, 1986
In this paper, we consider models of systems whose components have dependent lifelengths and are imperfectly repaired upon failure until they are scrapped. First, assuming that no more than one component can fail at a time, we study two models that describe imperfect repairs, and derive the resulting density and other probabilistic quantities of ...

Summary: Causal reasoning is important to human reasoning. It plays an essential role in day-to-day human decision-making. Human understanding of causality is necessarily imprecise, imperfect, and uncertain. Soft computing methods may be able to provide the approximation tools needed. In order to algorithmically consider causes, imprecise causal models
