Development of a software package with GUI for the evaluation of monolithicity factors of RC jacketed columns

2023

The design of reinforced concrete (RC) jacketing for retrofitting substandard columns is a common practice when approaching the structural rehabilitation design of existing structures. In this framework, international technical codes suggest to assume the hypothesis of monolithic section and finally affecting the deduced performances by some empirical factors, known in the literature as monolithicity factors. The assessment of these coefficients is a difficult task, and only some rough assumptions can be found in the modern codes. This paper presents the development of a software package able to perform the static non-linear analysis of RC jacketed columns and evaluating the actual value of…

SISTEMI PASSIVI PER L’INDOOR COMFORT: LA GESTIONE DELLE SERRE SOLARI IN REGIME ESTIVO

2019

La radiazione solare costituisce una fonte inesauribile di energia. Negli ultimi anni il mercato edilizio è stato invaso dall’applicazione di sistemi attivi (pannelli solari, etc...), non considerando le più valide alternative passive per il risparmio energetico. Oggi le mutate esigenze connesse all’evoluzione del concetto stesso di benessere ambientale richiedono una nuova coniugazione delle esperienze della tradizione costruttiva con le complessità dell’organizzazione tecnologica e i bisogni dell’utenza. La serra solare è un elemento architettonico complesso che consente un condizionamento sia invernale che estivo. Progettare sistemi passivi vetrati integrati con l’involucro permette al c…

EntityBot: Supporting Everyday Digital Tasks with Entity Recommendations

2021

Everyday digital tasks can highly benefit from systems that recommend the right information to use at the right time. However, existing solutions typically support only specific applications and tasks. In this demo, we showcase EntityBot, a system that captures context across application boundaries and recommends information entities related to the current task. The user’s digital activity is continuously monitored by capturing all content on the computer screen using optical character recognition. This includes all applications and services being used and specific to individuals’ computer usages such as instant messaging, emailing, web browsing, and word processing. A linear model is then …

Exploiting community detection to recommend privacy policies in decentralized online social networks

2018

The usage of Online Social Networks (OSNs) has become a daily activity for billions of people that share their contents and personal information with the other users. Regardless of the platform exploited to provide the OSNs’ services, these contents’ sharing could expose the OSNs’ users to a number of privacy risks if proper privacy-preserving mechanisms are not provided. Indeed, users must be able to define its own privacy policies that are exploited by the OSN to regulate access to the shared contents. To reduce such users’ privacy risks, we propose a Privacy Policies Recommended System (PPRS) that assists the users in defining their own privacy policies. Besides suggesting the most appro…

Searching the internet for learning materials through didactic indicators

2007

Internet offers a huge amount of didactic materials that can be used in creating new online courses. However, those materials need a deep analysis to understand their context and contents before their potential use. As a consequence, the search of didactic material in internet is often quite tedious and time consuming so the searcher usually limits his/her analysis to the first found web pages . To help users in finding efficiently and timely the most appropriate online materials, we have developed a system, called SAXEF (System for Automatic eXtraction of lEearning object Features), that is capable to automatically extract the didactic indicators (a sort of DNA) of any web page (or group o…

USER- AND CONTEXT-ORIENTED CRITERIA FOR ASSESMENT OF HIGH EFFICIENCY POLYGENERATION PLANTS FOR BUILDINGS APPLICATIONS

2013

The eligibility criteria adopted to assess polygeneration plants as “highly efficient” can play a determinant role in favouring or discouraging the market growth of polygeneration systems, especially for buildings applications where economic viability is often more difficult to achieve. Basing on the current European framework, in this paper the opportunity to adopt user- and context-oriented criteria is discussed. After having identified three buildings with different uses (a large hotel, a hospital and an office building), the optimal layout and operation strategy of a polygeneration plant serving each building is determined; then, ex-post processing of economic and energetic results is u…

Multi-Agent Systems as Effective Tools for the User-Based Thermal Comfort: an Introduction

2010

Through the paper the characterization of a comfort model, enriching that proposed by Fanger with an adaptive approach, is carried out using a Multi Agent System (MAS). This is a well suited coordinated set of Intelligent Agents, that are software applications interacting in order to follow user in his own needs and preferences in relation to indoor comfort, adapting to the changes of context variables. As a matter of fact, MAS are systems aware of the scenery where users live, following them in their own needs and preferences and adapting to their expectations. Indeed, thermal comfort conditions in the built environment are strictly related not only to the thermal and geometric building fe…

Efficient FPGA Implementation of a Knowledge-Based Automatic Speech Classifier

2005

Speech recognition has become common in many application domains, from dictation systems for professional practices to vocal user interfaces for people with disabilities or hands-free system control. However, so far the performance of Automatic Speech Recognition (ASR) systems are comparable to Human Speech Recognition (HSR) only under very strict working conditions, and in general far lower. Incorporating acoustic-phonetic knowledge into ASR design has been proven a viable approach to rise ASR accuracy. Manner of articulation attributes such as vowel, stop, fricative, approximant, nasal, and silence are examples of such knowledge. Neural networks have already been used successfully as dete…

Mobile Interface for Content-Based Image Management

2010

People make more and more use of digital image acquisition devices to capture screenshots of their everyday life. The growing number of personal pictures raise the problem of their classification. Some of the authors proposed an automatic technique for personal photo album management dealing with multiple aspects (i. e., people, time and background) in a homogenous way. In this paper we discuss a solution that allows mobile users to remotely access such technique by means of their mobile phones, almost from everywhere, in a pervasive fashion. This allows users to classify pictures they store on their devices. The whole solution is presented, with particular regard to the user interface impl…
