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)
The aim of this work is to continue the cooperation on Fixed WiMAX experimental propagation characterization between Instituto de Telecomunicações — DEM of University of Beira Interior, Portugal, Fondazione Ugo Bordoni and the Department of Electronics and Information Systems of the University of Bologna, both from Italy. The field(More)
A competitive manufacturing enterprise depends on a high level performance of its processes. In the metal-mechanic industry, such a requirement is pursued through the development of reliable monitoring systems. These systems must assure reliable information about the process itself, and about the machine's parameters. This paper proposes an efficient(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)
This paper claims to show a new concept of a robot, that uses joints of accessories, helping its displacement along transmission lines, also presenting low cost maintenance and easy operation. There were developed some series of accessories, which turn the robot into a simple engine, capable of moving along transmission lines, moving over suspension and(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)
iCO<sub>2</sub> is a networked game that aims to collect human driving behavior data at scale and help researchers better understand how people apply eco-driving practices. iCO<sub>2</sub> is an integrated multiplatform game that can be accessed via Web client on Facebook and iPad clients, and supports a shared traffic experience among its users. Here, the(More)
