High-Efficiency Video Coding (HEVC) is the latest video coding standard of the Joint Collaborative Team on Video Coding (JCT-VC). HEVC noticeably improves compression performance when comparing with previous standards such as H264, providing a major leap forward in video compression technology. However this improvement is achieved increasing the complexity of the encoding process. In this paper an...
In aircraft applications, there has been an increasing trend related with the More Electric Aircraft (MEA), which results in rapid rise in the electrical power demand on-board. One of its goals lies in minimizing weight and volume of the electrical subsystem while maintaining good power quality and efficiency. The main purpose of this paper is to present and analyze an electrical design of a three-phase...
Topological features are very seldom exploited in image processing, also due to the complexity of their extraction. When topological features are used, densitometric information are usually not considered at the same time. The simultaneous exploitation of both kinds of features, as proposed in this paper, allows a more appropriate automatic processing of digital images. A novel image segmentation...
A new technological solution to improve the beam-loss protection of silicon strip sensors used in large High Energy Physics experiments is presented. In the current ATLAS-SCT, sensors have Punch-Through protection (PTP) structures included to develop low impedance from the strip to the bias ring in case large voltages exceed some threshold that could damage the strip coupling capacitance. Previous...
This paper describes Metabolic.Care, a sub-project that integrates hardware and software with the main goal of implementing a solution that generates warnings for the diagnosis on patients with diabetic foot. This paper also describes the adopted strategies and best practices found to solve the problems.
This paper describes a perspective on medical information integration as implemented by the Portuguese Program TICE.Healthy. The eight subprojects that integrate TICE.Healthy share a common database for medical data, and exchange data using standard formats. Because the subprojects deal with data of different nature, strategies were developed to allow the effective integration of this data. This paper...
This paper presents the main aspects observed in analyzing Complex Voltage Unbalance Factor (CVUF) behavior resulting from the variation of voltage magnitudes and angles. The goal is to identify possible incoherencies regarding the use of the CVUF, and also to investigate whether this factor is more sensitive to variations in magnitude or angles under various voltage unbalance conditions. This study...
The tutorial refers to the need for all equipment and facilities related to human health must be adequately verified in calibration and functionality, as any calibration error, indicating graphic display or measured performance parameters can become a source of serious problems for patients. Therefore there is a line of important work in Biomedical Engineering, dedicated to the creation of complementary...
