Network Architecture, Security Issues, and Hardware Implementation of a Home Area Network for Smart Grid
No full textA flexible home monitoring platform for patients affected by chronic heart failure directly integrated with the remote Hospital Information System
No full textToday Chronic Heart Failure (CHF) represents one of leading cause of hospitalization among chronic disease, especially for elderly citizens, with a consequent considerable impact on patient quality of life, resources congestion and healthcare costs for the National Sanitary System. The current healthcare model is mostly in-hospital based and consists of periodic visits, but unfortunately it does not allow to promptly detect exacerbations resulting in a large number of re-hospitalization. Recently physicians and administrators identify telemonitoring systems as a strategy able to provide effective and cost efficient healthcare services for CHF patients, ensuring early diagnosis and treatments in case of necessity. This work presents a complete and integrated ICT solution to improve the management of chronic heart failure through the remote monitoring of vital signs at patient home, able to connect in-hospital care of acute syndrome with out-of-hospital follow-up. The proposed platform represents the patient's interface, acting as link between biomedical sensors and the data collection point at the Hospital Information System (HIS) in order to handle in transparent way the reception, analysis and forwarding of the main physiological parameters

Design of a NoC Interface Macrocell with Hardware Support of Advanced Networking Functionalities
No full textThe paper presents the design and the caracterization in nanoscale CMOS technology of a Network Interface (NI) for on-chip communication infrastructure with hardware support of advanced networking functionalities: store&forward transmission, error management, power management, ordering handling, security, QoS management, programmability, end-to-end protocol interoperability, remapping. The design has been conceived as a scalable architecture: the advanced features can be added on top of a basic NI core implementing data packetization and conversion of protocols, frequency and data size between the connected IP core and the on chip network. The NI can be configured to reach the desired trade-off between supported services and circuit complexity
Remote monitoring of vital signs in patients with chronic heart failure: Sensor devices and data analysis perspective
No full textNowadays Chronic Heart Failure (CHF) represents
one of the leading causes of hospital admission among chronic
diseases, especially for elderly citizens. Monitoring of vital signs,
performed at patients’ home, has been identified by physicians
and administrators as an important strategy to early detect and
treat the alterations in vital signs that precede the acute
syndromes, in order to reduce the number of consequent
hospitalizations and related costs. A basic set of relevant vital
parameters consists of ECG, SpO2, Blood Pressure and Weight,
acquired in non-invasive fashion and processed both in threshold
comparisons and for trends extraction. This paper describes,
from the sensors and data processing perspective, a complete and
integrated ICT solution to improve the provisioning of healthcare
service for CHF patients able to connect in-hospital care of acute
phase with out-of-hospital follow-up
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
