Radioembolization (RE) with 90Y microspheres has been recognized as an emerging treatment strategy for patients with liver tumors either primary or secondary. New tools for complex patient dosimetry, based on real absorbed dose distribution to the normal liver and tumor are under development by our research group at the Champalimaud Centre for the Unknown (CCU), Champalimaud Foundation (CF). Furthermore,...
Serious games based physical therapy is currently gaining a lot of interest by the physiotherapists and game developers that are using new natural user interfaces devices to assure an easy interaction between the user under rehabilitation and his avatar immersed in a virtual reality scenario. Arm motion training, as part of stroke rehabilitation program, can be one of the main objectives of the serious...
The purpose of this paper is to present wireless and mobile solutions as so as the developments reported by the authors in the area of geographic information systems to asses the anthropogenic factors influence on estuary life. Thus, a set of distributed measurement systems, including water quality and air quality sensors characterized by wireless data communication capabilities, are described in...
Condition monitoring is used to increase machinery availability and machinery performance, reducing consequential damage, increasing machine life, reducing spare parts inventories, and reducing breakdown maintenance. An efficient real time vibration measurement and analysis instruments is capable of providing warning and predicting faults at early stages. In this paper, a new methodology for the implementation...
This paper presents a combination of two techniques for high resolution ultrasonic distance measurements in air. The first is the cross-correlation between transmitted and received signals to determine the Time-Of-Flight (TOF), and the second is the sine-fitting to determine the phase-shift between these signals. Sine-fitting can estimate the phase-shift with very high accuracies. The result of this...
