Aalto’s Principles of Urban Space and Planning in connection to William Wurster and Lewis Mumford
2015
Il saggio affronta il tema dei principi sullo spazio urbano e sul progetto urbano di Alvar Aalto, in rapporto alla influenza di Willam Wurster a Lewis Mumford. Aalto ha fatto circa 50 progetti urbanistici, molti dei quali poco conosciuti dagli studiosi. Essi variano da progetti contestuali dentro la città a progetti residenziali, centri civici, università, cimiteri, piani regionali. Sia in Finlandia, che soprattutto durante i soggiorni di Aalto in USA i contatti di Aalto e Wurster sono conosciuti, quelli con Mumford inevitabili. I progetti urbani e gli scritti di Aalto sono analizzati in relazione a quest duplice influenza. The paper focuses on Aalto's principles about urban space and plann…
Homeward : caratteri, strategie compositive, poetiche dell’abitare
2020
Il volume raccoglie dei saggi elaborati a partire da alcune lectures universitarie che, attraverso l’esposizione e il commento di alcuni edifici esemplari, testimoniano la possibile ricerca di un testo “ideale”. Una traccia di fondo tiene insieme maestri come Soane, Schinkel, Loos, Asplund, Taut, Mies van der Rohe, Le Corbusier, Kahn, e si riflette nelle loro opere: tutti hanno avuto una grande passione per l’architettura classica. Dai più lontani nel tempo sino a quelli più prossimi, c’è stata una trasmissione di questioni, di principi e insegnamenti come discendenze, lungo trame riscontrabili in filigrana. Si indaga con ampi riferimenti critici il legame delle opere con le circostanze che…
Accommodative Stimulus-Response Curve with Emoji Symbols
2017
Purpose. To evaluate the static measurement of the accommodative stimulus-response curve with emoji symbols. Methods. The accommodative stimulus-response curve was measured in 18 subjects using a Hartmann-Shack sensor to obtain the objective accommodative response from the Zernike defocus term. Measurements were acquired at different accommodative demands, from 0 to 3 D with a step of 0.5 D. Detailed and nondetailed emoji targets were used with two different sizes, corresponding to the two most common visual angles used in smartphones. Results. A regression analysis was performed to fit the mean results obtained for each target. The determination coefficient was R2≥0.988 for all targets. Fo…

An architecture for autonomous agents exploiting conceptual representations
1998
An architecture for autonomous agents is proposed that integrates the functional and the behavioral approaches to robotics. The integration is based on the introduction of a conceptual level, linking together a subconceptual, behavioral, level, and a linguistic level, encompassing symbolic representation and data processing. The proposed architecture is described with reference to an experimental setup, in which the robot task is that of building a significant description of its working environment. © 1998 Elsevier Science B.V.

P4571PFA-100, a test of platelet adhesion/aggregation, predicts cardiovascular events after an acute coronary syndrome and can help in the decision-m…
2019
Abstract Background The dual antiplatelet therapy (DAPT) duration is a matter of great interest among cardiologists. Because of the conflicting evidences and the necessity to balance the reduction in major cardiac events (MACE) occurrence and the risk of major bleedings after an acute coronary syndrome (ACS), there is a general consensus on prolonging DAPT on an individual basis. There is less consensus on which parameters are to be evaluated. Nowadays tests of platelet reactivity are not included in the decision-making. Few data are available on the prognostic value of aspirin response tests that are sensitive to other mediators of platelet adhesion and aggregation in vivo under flow condi…
A Hierarchical Detection and Response System to Enhance Security Against Lethal Cyber-Attacks in UAV Networks
2018
International audience; Unmanned aerial vehicles (UAVs) networks have not yet received considerable research attention. Specifically, security issues are a major concern because such networks, which carry vital information, are prone to various attacks. In this paper, we design and implement a novel intrusion detection and response scheme, which operates at the UAV and ground station levels, to detect malicious anomalies that threaten the network. In this scheme, a set of detection and response techniques are proposed to monitor the UAV behaviors and categorize them into the appropriate list (normal, abnormal, suspect, and malicious) according to the detected cyber-attack. We focus on the m…
Utility-based resource allocations in multi-hop wireless networks
2011
It is well known that CSMA (Carrier Sense Multiple Access) protocols exhibit very poor performance in case of multi-hop transmissions, because of inter-link interference due to imperfect carrier sensing. Since ad-hoc networks based on multihop packet deliveries are becoming more and more common in different application and networking scenarios, different medium access control extensions are currently considered for improving the channel utilization efficiency. In this paper, we propose a simple approach based on preallocating temporal slots in which different sets of nodes are allowed to contend for the channel access, which can significantly improve CSMA performance with limited signaling …
Middleware with QoS Support to Control Intelligent Systems
2008
This paper presents the architecture of a middleware for control component-based distributed systems. The fundamental idea underlying this architecture is the use of a hierarchical communications structure called "logical namespace tree" and a structured set of control processes interconnected, called "logical sensors graph". This architecture is named frame sensor adapter control (FSA-Ctrl). The aim of FSA-Ctrl is to provide a simple interface to specify the control actions and ensure a communication with some specified QoS parameters restrictions. In this architecture both systems, communication and control, manages the QoS policies. The communication system is based on the data distribut…
An FPGA-Based Adaptive Fuzzy Coprocessor
2005
The architecture of a general purpose fuzzy logic coprocessor and its implementation on an FPGA based System on Chip is described. Thanks to its ability to support a fast dynamic reconfiguration of all its parameters, it is suitable for implementing adaptive fuzzy logic algorithms, or for the execution of different fuzzy algorithms in a time sharing fashion. The high throughput obtained using a pipelined structure and the efficient data organization allows significant increase of the computational capabilities strongly desired in applications with hard real-time constraints.
