The biggest single obstacle to building effective augmented reality (AR) systems is the lack of accurate wide-area sensors for tracking the locations and orientations of objects in an environment. Active (sensor-emitter) tracking technologies require powered-device installation, limiting their use to prepared areas that are relatively free of natural or man-made interference sources. Vision-bas...

This paper discusses a number of issues arose during the deployment of a commercial robotic platform in a hospital scenario. In particular, a realistic case study and installation process at Polyclinic of Modena (Italy) is described, where robots have to accomplish two different types of tasks, namely drugs delivery and waste transportation. The lesson learned is that the design of a robot to b...

Longer amyloid-beta (Aβ) peptides (43 to 49 amino acids) play essential roles in the pathology of Alzheimer's disease (AD). The difficulty in the preparation of longer Aβ peptides is still an obstacle to elucidate their roles in AD. Herein we report a robust and efficient strategy for the chemical synthesis of longer Aβ peptides (Aβ48 and Aβ49). A key feature of this method is the installation ...

Introducing Electromagnetic Interference and Electromagnetic Compatibility, or “The Art of Black Magic”, for engineering students might be a terrifying experience both for students and tutors. Removing the obstacle of large, expensive facilities like a fully fitted EMC laboratory and hours of complex theory, this paper demonstrates a design of a laboratory setup for student exercises, giving st...

Almost all Augmented Reality (AR) systems work indoors. Outdoor AR systems offer the potential for new application areas. The biggest single obstacle to building effective AR systems is the lack of accurate wide-area sensors for trackers that report the locations and orientations of objects in an environment. Active (sensor-emitter) tracking technologies require powered-device installation, lim...

A general domain decomposition scheme based on the use of complex sources is presented for the electromagnetic analysis of complex antenna and/or scattering problems. The analysis domain is decomposed into separate subdomains whose interactions are described through a network formalism, where the ports are associated with complex point source (CPS) beams radially emerging from the subdomain bou...

Operation Theatre (OT) is the most important area where precise controlled on indoor air quality is required because it is directly related to patient health and its recovery period. This work aims to study and visualize the airflow distribution of conventional flat air diffuser ventilation system and newly designed angular air ventilation system in OT. Angular Air Distribution (AAD) system is ...

The ever-increasing quantities of structured knowledge on the Web and the impending need of multilinguality and cross-linguality for information access pose new challenges but at the same time open up new opportunities for knowledge extraction research. In this regard, cross-lingual semantic annotation has emerged as a topic of major interest and it is essential to build tools that can link wor...
