This article presents research on error detection and prediction algorithms in robotics. Errors, defined as either agent error or Co-net error, are analyzed and compared. Three new error detection and prediction algorithms (EDPAs) are then developed, and validated by detecting and predicting errors in typical pick and place motions of an Adept Cobra 800(More)
The paper presents a new intensity-based 3D-2D image registration algorithm for automatic pretreatment validation in radiotherapy. The novel aspects of the algorithm includes a hybrid cost function developed based on partial digitally reconstructed radiographs (DRRs) generated along projected anatomic contours and level set for similarity measurement, and a(More)
The purpose of this article is to review the key emerging innovations in laser and photonics systems as well as their design and integration, focusing on challenges and opportunities for solutions of societal challenges. Developments, their significance, and frontier challenges are explained in advanced manufacturing, biomedicine and healthcare, and(More)
In the present study, we investigated the relationship among three emotion-motivation systems (adult attachment, romantic love, and sex). We recorded event-related potentials in 37 healthy volunteers who had experienced romantic love while they viewed SEX, LOVE, FRIEND, SPORT, and NEUTRAL images. We also measured adult attachment styles, level of passionate(More)
a r t i c l e i n f o Logic needed for decision support to detect and resolve airport surface conflicts is defined in this article based on complex network theory. In this article, conflicts in airport surface operations are defined, along with a methodology to model and analyze airport surface constraints. The conflict detection and resolution logic take(More)
