Tecniche di Test Innovative per la Caratterizzazione di Memorie a Gate Flottante

L’affidabilità nella ritenzione dei dati memorizzati è una delle problematiche fondamentali delle memorie flash; esse vengono normalmente testate, in produzione con procedure specifiche implementate su ATE (Automated Test Equipments), per rilevare problemi di lettura, programmazione e cancellazione; vengono inoltre provate altre procedure per identificare possibili faults e per il corretto trimming dei parametri interni. Oggi, il testing classico con ATE è supportato dalle tecniche BIST (Built-In-Self-Test), tramite le quali si prevede in progetto, all’interno dei circuiti integrati, una parte di hardware e software supplementari per permettere l’auto-test (funzionale e/o parametrico), così…

Benefits of a translucent building envelope made of DSC-integrated glass blocks

2015

The aim of this paper is to analyse the benefits deriving from the replacement of the glazed façades of an office building located in Palermo (Sicily) with a new translucent BIPV envelope made of multifunctional glass block panels integrated with Dye-sensitized Solar Cells (DSCs). The analysed 11-storey building is cladded by a curtain wall determining high management costs, especially during summer, in order to maintain indoor comfort. After the design of the building envelope and of the components for the connection of the glass block panels with existing load bearing structure, the energy performance of the building, before and after the replacement of its envelope, were analysed with th…

Effect of Short-Term and UV Irradiation Aging on the Behaviour of SBS-Modified Bitumen

2022

To obtain road bitumen with improved temperature and fatigue resistance, polymers and/or rubbers could be added to it. A particularly suitable polymer for bitumen modification is styrene-butadiene-styrene (SBS) copolymer but limited information is available about the ageing behaviour of modified binders. In this work, two neat bitumens, with different penetration grades, and two SBS-modified bitumens, containing different SBS amounts, were selected, and their short-term and UVB ageing behaviour were investigated considering dynamic shear rheometry and Attenuated Total Reflectance-Fourier Transformation InfraRed spectroscopy (ATR-FTIR). Short-time ageing behaviour was investigated performing…

Analysis of load balancing and interference management in heterogeneous cellular networks

2017

To meet the current cellular capacity demands, proactive offloading is required in heterogeneous cellular networks (HetCNets) comprising of different tiers of base stations (BSs), e.g., small-cell BSs (sBSs) and conventional macro-cell BSs (mBSs). Each tier differs from the others in terms of BS transmit power, spatial density, and association bias. Consequently, the coverage range of each tier BSs is also different from others. Due to low transmit power, a fewer number of users are associated to an sBS as compared with mBS. Thus, inefficient utilization of small-cell resources occurs. To balance the load across the network, it is necessary to push users to the underloaded small cells from …

Microstructure and rheological response of laboratory-aged SBS-modified bitumens

2019

Polymer additives are widely used to improve the performance of road bitumens including their resistance to hardening during oxidation, although their oxidative inhibitor effect has not been well documented. This study aims to investigate the effect of laboratory-simulated ageing on the microstructure, and rheological properties of Polymer Modified Bitumens (PMBs) prepared with a Styrene-Butadiene-Styrene (SBS) copolymer and sulphur as a cross-linker. The laboratory ageing was conducted through the Rolling Thin Film Oven (RTFO) and the Pressure Aging Vessel (PAV) procedures. The unaged and aged binders were characterised using the Multiple Stress Creep and Recovery (MSCR) test, Gel Permeati…
