The iris is regarded as one of the most useful traits for biometric recognition and the dissemination of nationwide iris-based recognition systems is imminent. However, currently deployed systems rely on heavy imaging constraints to capture near infrared images with enough quality. Also, all of the publicly available iris image databases contain data(More)
Mild cognitive impairment (MCI) is a nosological entity associated with a higher risk of developing dementia. Previous evidence indicates that behavioral and psychological symptoms of dementia (BPSDs) frequently occur in individuals of MCI. These neuropsychiatric manifestations may predict conversion to dementia. However, no updated systematic review has(More)
Virtual environments offer an ideal setting to develop intelligent training applications. Yet, their ability to support complex procedures depends on the appropriate integration of knowledge-based techniques and natural interaction. In this article, we describe the implementation of an intelligent rehearsal system for biohazard laboratory procedures, based(More)
Layered and cooperative elements such as femto-cells and relays can improve performance or energy efficiency in mobile networks; however, they consume energy per se and their durations in operational state must therefore be minimised. This paper investigates the use of relays in WiMAX network deployments and concentrates on the cost/revenue performance and(More)
