Condition Based Maintenance of Periodically Inspected Systems

Condition based maintenance (CBM) is a powerful tool for improvement of system reliability and reduction of system downtime. This research considers CBM under which the system state is periodically observed with or without observational error, and maintenance is imperfect. System availability is maximized by determining the optimal maintenance threshold and the time interval between consecutive...

Availability of Periodically Inspected Systems with Markovian Wear and Shocks

We analyze a periodically inspected system with hidden failures in which the rate of wear is modulated by a continuous-time Markov chain and additional damage is induced by a Poisson shock process. We derive explicitly the system’s lifetime distribution and mean time to failure, as well as the limiting average availability. The main results are illustrated through two numerical examples.

Software Tools for Recording Image Inspection Processes

We present an information gathering system for medical image inspection that can record and replay computerand human-centric information. Computer-centric information consists of static measurements about image drawings and associated textual annotations, as well as, dynamic measurements about image frame selection, zoom level, image panning, sub-area cropping, and mouse movement. Human-centric...

When is a compliment not a compliment? Evaluating expressions of positive stereotypes

Unlike negative stereotypes, positive stereotypes are often perceived as admirable qualities, and expressions of such beliefs may be intended as compliments toward group members. Two experiments were conducted to examine how the targets of positive stereotypes evaluate others who express such stereotypic “compliments.” In Study 1, Black participants evaluated a White student who praised the ath...
