<p class="card-text"><strong>Abstract:</strong></p> The “Guidelines for Risk Classification, Safety Assessment, and Structural Health Monitoring of Existing Bridges” were recently approved by the Italian Government to define technical standards for managing the national network of existing bridges. These guidelines provide a framework for risk mitigation and safety assessment of bridges, which are essential elements of the built environment and form the basis for the operation of transport systems. Within the guideline framework, a workflow based on three main points was proposed: (1) risk-based, i.e., based on typical parameters of hazard, vulnerability, and exposure; (2) multi-level, i.e., including six assessment levels of increasing complexity; and (3) multirisk, i.e., assessing structural/foundational, seismic, hydrological, and landslide risks. The paper focuses on applying the Italian Guidelines to specific case studies, aiming to identify the parameters that predominantly influence the determination of the “class of attention”. The significance of each parameter is determined via sensitivity analysis. Additionally, recommendations for enhancing the process of assigning the class of attention are proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge%20safety%20assessment" title="bridge safety assessment">bridge safety assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=Italian%20guidelines%20implementation" title=" Italian guidelines implementation"> Italian guidelines implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20classification" title=" risk classification"> risk classification</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20health%20monitoring" title=" structural health monitoring"> structural health monitoring</a> </p> <a href="https://publications.waset.org/abstracts/184665/application-of-italian-guidelines-for-existing-bridge-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184665.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">55</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> About Multi-Resolution Techniques for Large Eddy Simulation of Reactive Multi-Phase Flows</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giacomo%20Rossi">Giacomo Rossi</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernardo%20Favini"> Bernardo Favini</a>, <a href="https://publications.waset.org/abstracts/search?q=Eugenio%20Giacomazzi"> Eugenio Giacomazzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Franca%20Rita%20Picchia"> Franca Rita Picchia</a>, <a href="https://publications.waset.org/abstracts/search?q=Nunzio%20Maria%20Salvatore%20Arcidiacono"> Nunzio Maria Salvatore Arcidiacono</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A numerical technique for mesh refinement in the HeaRT (Heat Release and Transfer) numerical code is presented. In the CFD framework, Large Eddy Simulation (LES) approach is gaining in importance as a tool for simulating turbulent combustion processes, also if this approach has an high computational cost due to the complexity of the turbulent modeling and the high number of grid points necessary to obtain a good numerical solution. In particular, when a numerical simulation of a big domain is performed with a structured grid, the number of grid points can increase so much that the simulation becomes impossible: this problem can be overcame with a mesh refinement technique. Mesh refinement technique developed for HeaRT numerical code (a staggered finite difference code) is based on an high order reconstruction of the variables at the grid interfaces by means of a least square quasi-ENO interpolation: numerical code is written in modern Fortran (2003 standard of newer) and is parallelized using domain decomposition and message passing interface (MPI) standard. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LES" title="LES">LES</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-resolution" title=" multi-resolution"> multi-resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=ENO" title=" ENO"> ENO</a>, <a href="https://publications.waset.org/abstracts/search?q=fortran" title=" fortran"> fortran</a> </p> <a href="https://publications.waset.org/abstracts/11679/about-multi-resolution-techniques-for-large-eddy-simulation-of-reactive-multi-phase-flows" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">366</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Mathematical Games with RPG and Sci-Fi Elements to Enhance Motivation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santiago%20Moll%20Lopez">Santiago Moll Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Erica%20Vega%20Fleitas"> Erica Vega Fleitas</a>, <a href="https://publications.waset.org/abstracts/search?q=Dolors%20Rosello%20Ferragud"> Dolors Rosello Ferragud</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Manuel%20Sanchez%20Ruiz"> Luis Manuel Sanchez Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Antonio%20Mora%C3%B1o%20Fernandez"> Jose Antonio Moraño Fernandez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Game-based learning (GBL) is becoming popular in education. Learning through games offers students a motivating experience related to the social aspect of games. Among the significant positive outcomes are promoting positive emotions and collaboration, improving the assimilation of concepts, and creating an attractive and dynamic environment standout. This work presents a study of the design and implementation of games created with RPG Maker MZ software with a Sci-Fi storytelling environment for developing specific and transversal skills in a Mathematics subject at the Beng in Aerospace Engineering. Games were applied during regular classes and as a part of a Flip-Teaching methodology to increase the motivation and the assimilation of mathematical concepts in an engaging way. The key features of the games were the introduction of avatar design and the promotion of collaboration among students. Students' opinions and grades obtained in the activities and exams showed increased motivation and a significant improvement in their performance compared with other groups or past students' performances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=game-based%20learning" title="game-based learning">game-based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=rol%20games" title=" rol games"> rol games</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematics" title=" mathematics"> mathematics</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20fiction" title=" science fiction"> science fiction</a> </p> <a href="https://publications.waset.org/abstracts/163888/mathematical-games-with-rpg-and-sci-fi-elements-to-enhance-motivation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163888.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Preliminary Short-Term Results of a Population of Patients Treated with Mitraclip Therapy: One Center Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rossana%20Taravella">Rossana Taravella</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilberto%20M.%20Cellura"> Gilberto M.

We describe in this article the preliminary results of primary effectiveness endpoint. Background: Percutaneous Mitral Repair is being developed to treat severe mitral regurgitation (MR), with increasing real-world cases of functional MR (FMR). In the EVEREST (Endovascular Valve Edge-to-Edge Repair Study)II trial, the percutaneous device showed superior safety but less reduction in MR at 1year. 4-year outcomes from EVEREST II trial showed no difference in the prevalence of moderate-severe and severe MR or mortality at 4years between surgical mitral repair and percutaneous approach. Methods: We analysed retrospectively collected data from one center experience in Italy enrolled from January 2011 to December 2016. The study included 62 patients [mean age 74±11years, 43 men (69%)] with MR of at least grade3+. Most of the patients had functional MR, were in New York Heart Association (NYHA) functional class III or IV, with a large portion (78%) of mild-to-moderate Tricuspid Regurgitation (TR). One or more clips were implanted in 67 procedures (62 patients). Results and Conclusions: Severity of MR was reduced in all successfully treated patients,54(90%) were discharged with MR≤2+ (primary effectiveness endpoint). Clinical 1-month follow-up data showed an improvement in NYHA functional class (42 patients (70%) in NYHA class I-II). 60 of 62 (97 %) successfully treated patients were free from death and mitral valve surgery at 1-month follow-up. MitraClip therapy reduces functional MR with acute MR reduction to <2+ in the great majority of patients, with a large freedom from death, surgery or recurrent MR in a great portion of patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MitraClip" title="MitraClip">MitraClip</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20regurgitation" title=" mitral regurgitation"> mitral regurgitation</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20valves" title=" heart valves"> heart valves</a>, <a href="https://publications.waset.org/abstracts/search?q=catheter-based%20therapy" title=" catheter-based therapy"> catheter-based therapy</a> </p> <a href="https://publications.waset.org/abstracts/68742/preliminary-short-term-results-of-a-population-of-patients-treated-with-mitraclip-therapy-one-center-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68742.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Non Commutative Lᵖ Spaces as Hilbert Modules</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salvatore%20Triolo">Salvatore Triolo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We discuss the possibility of extending the well-known Gelfand-Naimark-Segal representation to modules over a C*algebra.

F-IVT is an innovative actuation system to power artificial knee joint with energy recovery capabilities. Its key and non-conventional elements are a flywheel, that acts as a mechanical energy storage system, and an Infinitely Variable Transmission (IVT). The design of the F-IVT can be optimized for a certain walking condition, resulting in a heavy reduction of both the electric energy consumption and of the electric peak power.

Fertigation dose, frequency and nutrient concentration must be planned with the objective of reaching an optimal crop growth by limiting the utilized resources and the associated costs. The definition of efficient fertigation strategies is a complex problem since fertigation requirements vary on the basis of different factors, and crops are sensitive to small variations on fertigation parameters. To the best of author knowledge, a small-scale test bench that is flexible for both nutrient solution preparation and precise irrigation is currently missing, limiting the investigations in standard practices for soilless culture. Starting from the analysis of the state of the art, this paper proposes a small-scale system that is potentially able to concurrently test different fertigation strategies. The system will be designed and implemented throughout a three year project started on August 2018. However, due to the importance of the topic within current challenges as food security and climate change, this work is spread considering that may inspire other universities and organizations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soilless%20culture" title="soilless culture">soilless culture</a>, <a href="https://publications.waset.org/abstracts/search?q=fertigation" title=" fertigation"> fertigation</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20bench" title=" test bench"> test bench</a>, <a href="https://publications.waset.org/abstracts/search?q=small-scale" title=" small-scale"> small-scale</a>, <a href="https://publications.waset.org/abstracts/search?q=automation" title=" automation"> automation</a> </p> <a href="https://publications.waset.org/abstracts/99392/a-small-scale-flexible-test-bench-for-the-investigation-of-fertigation-strategies-in-soilless-culture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99392.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Optical Flow Based System for Cross Traffic Alert </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giuseppe%20Spampinato">Giuseppe Spampinato</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvatore%20Curti"> Salvatore Curti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivana%20Guarneri"> Ivana Guarneri</a>, <a href="https://publications.waset.org/abstracts/search?q=Arcangelo%20Bruna"> Arcangelo Bruna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This document describes an advanced system and methodology for Cross Traffic Alert (CTA), able to detect vehicles that move into the vehicle driving path from the left or right side. The camera is supposed to be not only on a vehicle still, e.g. at a traffic light or at an intersection, but also moving slowly, e.g. in a car park. In all of the aforementioned conditions, a driver’s short loss of concentration or distraction can easily lead to a serious accident. A valid support to avoid these kinds of car crashes is represented by the proposed system. It is an extension of our previous work, related to a clustering system, which only works on fixed cameras. Just a vanish point calculation and simple optical flow filtering, to eliminate motion vectors due to the car relative movement, is performed to let the system achieve high performances with different scenarios, cameras and resolutions. The proposed system just uses as input the optical flow, which is hardware implemented in the proposed platform and since the elaboration of the whole system is really speed and power consumption, it is inserted directly in the camera framework, allowing to execute all the processing in real-time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clustering" title="clustering">clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20traffic%20alert" title=" cross traffic alert"> cross traffic alert</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20flow" title=" optical flow"> optical flow</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time" title=" real time"> real time</a>, <a href="https://publications.waset.org/abstracts/search?q=vanishing%20point" title=" vanishing point"> vanishing point</a> </p> <a href="https://publications.waset.org/abstracts/79933/optical-flow-based-system-for-cross-traffic-alert" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79933.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Design Guidelines for an Enhanced Interaction Experience in the Domain of Smartphone-Based Applications for Sport and Fitness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Pilloni">Paolo Pilloni</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabrizio%20Mulas"> Fabrizio Mulas</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvatore%20Carta"> Salvatore Carta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, several research studies point up that an active lifestyle is essential for physical and mental health benefits. Mobile phones have greatly influenced people’s habits and attitudes also in the way they exercise. Our research work is mainly focused on investigating how to exploit mobile technologies to favour people’s exertion experience. To this end, we developed an exertion framework users can exploit through a real world mobile application, called BLINDED, designed to act as a virtual personal trainer to support runners during their trainings. In this work, inspired by both previous findings in the field of interaction design for people with visual impairments, feedback gathered from real users of our framework, and positive results obtained from two experimentations, we present some new interaction facilities we designed to enhance the interaction experience during a training. The positive obtained results helped us to derive some interaction design recommendations we believe will be a valid support for designers of future mobile systems conceived to be used in circumstances where there are limited possibilities of interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20computer%20interaction" title="human computer interaction">human computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction%20design%20guidelines" title=" interaction design guidelines"> interaction design guidelines</a>, <a href="https://publications.waset.org/abstracts/search?q=persuasive%20mobile%20technologies%20for%20sport%20and%20health" title=" persuasive mobile technologies for sport and health"> persuasive mobile technologies for sport and health</a> </p> <a href="https://publications.waset.org/abstracts/20387/design-guidelines-for-an-enhanced-interaction-experience-in-the-domain-of-smartphone-based-applications-for-sport-and-fitness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20387.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">532</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Using Squeezed Vacuum States to Enhance the Sensitivity of Ground Based Gravitational Wave Interferometers beyond the Standard Quantum Limit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giacomo%20Ciani">Giacomo Ciani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper reviews the impact of quantum noise on modern gravitational wave interferometers and explains how squeezed vacuum states are used to push the noise below the standard quantum limit. With the first detection of gravitational waves from a pair of colliding black holes in September 2015 and subsequent detections including that of gravitational waves from a pair of colliding neutron stars, the ground-based interferometric gravitational wave observatories LIGO and VIRGO have opened the era of gravitational-wave and multi-messenger astronomy. Improving the sensitivity of the detectors is of paramount importance to increase the number and quality of the detections, fully exploiting this new information channel about the universe. Although still in the commissioning phase and not at nominal sensitivity, these interferometers are designed to be ultimately limited by a combination of shot noise and quantum radiation pressure noise, which define an envelope known as the standard quantum limit. Despite the name, this limit can be beaten with the use of advanced quantum measurement techniques, with the use of squeezed vacuum states being currently the most mature and promising. Different strategies for implementation of the technology in the large-scale detectors, in both their frequency-independent and frequency-dependent variations, are presented, together with an analysis of the main technological issues and expected sensitivity gain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gravitational%20waves" title="gravitational waves">gravitational waves</a>, <a href="https://publications.waset.org/abstracts/search?q=interferometers" title=" interferometers"> interferometers</a>, <a href="https://publications.waset.org/abstracts/search?q=squeezed%20vacuum" title=" squeezed vacuum"> squeezed vacuum</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20quantum%20limit" title=" standard quantum limit"> standard quantum limit</a> </p> <a href="https://publications.waset.org/abstracts/85856/using-squeezed-vacuum-states-to-enhance-the-sensitivity-of-ground-based-gravitational-wave-interferometers-beyond-the-standard-quantum-limit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85856.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Digital Twin of Real Electrical Distribution System with Real Time Recursive Load Flow Calculation and State Estimation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anosh%20Arshad%20Sundhu">Anosh Arshad Sundhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Giordano"> Francesco Giordano</a>, <a href="https://publications.waset.org/abstracts/search?q=Giacomo%20Della%20Croce"> Giacomo Della Croce</a>, <a href="https://publications.waset.org/abstracts/search?q=Maurizio%20Arnone"> Maurizio Arnone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital Twin (DT) is a technology that generates a virtual representation of a physical system or process, enabling real-time monitoring, analysis, and simulation. DT of an Electrical Distribution System (EDS) can perform online analysis by integrating the static and real-time data in order to show the current grid status and predictions about the future status to the Distribution System Operator (DSO), producers and consumers.

The nanochannel drug delivery system (nDS), a membrane fabricated with high precision silicon techniques, capable of zero-order release of drugs by exploiting diffusion transport at the nanoscale originated from the interactions between molecules with nanochannel surfaces, showed the flexibility of the sustained release in vitro and in vivo, over periods of time ranging from weeks to months. To improve the implantable bio nanotechnology, in order to create a system that possesses the key features for achieve the suitable release of therapeutics, the next generation of nDS has been created. Platinum electrodes are integrated by e-beam deposition onto both surfaces of the membrane allowing low voltage (<2 V) and active temporal control of drug release through modulation of electrostatic potentials at the inlet and outlet of the membrane’s fluidic channels. Hence, a tunable administration of drugs is ensured from the nanochannel drug delivery system. The membrane will be incorporated into a peek implantable capsule, which will include drug reservoir, control hardware and RF system to allow suitable therapeutic regimens in real-time. Therefore, this new nanotechnology offers tremendous potential solutions to manage chronic disease such as cancer, heart disease, circadian dysfunction, pain and stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanochannel%20membrane" title="nanochannel membrane">nanochannel membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=tunable%20release" title=" tunable release"> tunable release</a>, <a href="https://publications.waset.org/abstracts/search?q=personalized%20administration" title=" personalized administration"> personalized administration</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoscale%20transport" title=" nanoscale transport"> nanoscale transport</a>, <a href="https://publications.waset.org/abstracts/search?q=biomems" title=" biomems"> biomems</a> </p> <a href="https://publications.waset.org/abstracts/15827/tunable-control-of-therapeutics-release-from-the-nanochannel-delivery-system-nds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15827.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">314</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> A Machine Learning Approach for Anomaly Detection in Environmental IoT-Driven Wastewater Purification Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Cicceri">Giovanni Cicceri</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberta%20Maisano"> Roberta Maisano</a>, <a href="https://publications.waset.org/abstracts/search?q=Nathalie%20Morey"> Nathalie Morey</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvatore%20Distefano"> Salvatore Distefano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main goal of this paper is to present a solution for a water purification system based on an Environmental Internet of Things (EIoT) platform to monitor and control water quality and machine learning (ML) models to support decision making and speed up the processes of purification of water. A real case study has been implemented by deploying an EIoT platform and a network of devices, called Gramb meters and belonging to the Gramb project, on wastewater purification systems located in Calabria, south of Italy. The data thus collected are used to control the wastewater quality, detect anomalies and predict the behaviour of the purification system. To this extent, three different statistical and machine learning models have been adopted and thus compared: Autoregressive Integrated Moving Average (ARIMA), Long Short Term Memory (LSTM) autoencoder, and Facebook Prophet (FP). The results demonstrated that the ML solution (LSTM) out-perform classical statistical approaches (ARIMA, FP), in terms of both accuracy, efficiency and effectiveness in monitoring and controlling the wastewater purification processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20internet%20of%20things" title="environmental internet of things">environmental internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=EIoT" title=" EIoT"> EIoT</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=anomaly%20detection" title=" anomaly detection"> anomaly detection</a>, <a href="https://publications.waset.org/abstracts/search?q=environment%20monitoring" title=" environment monitoring"> environment monitoring</a> </p> <a href="https://publications.waset.org/abstracts/130838/a-machine-learning-approach-for-anomaly-detection-in-environmental-iot-driven-wastewater-purification-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130838.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Calculation of the Normalized Difference Vegetation Index and the Spectral Signature of Coffee Crops: Benefits of Image Filtering on Mixed Crops</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catalina%20Albornoz">Catalina Albornoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Giacomo%20Barbieri"> Giacomo Barbieri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Crop monitoring has shown to reduce vulnerability to spreading plagues and pathologies in crops. Remote sensing with Unmanned Aerial Vehicles (UAVs) has made crop monitoring more precise, cost-efficient and accessible. Nowadays, remote monitoring involves calculating maps of vegetation indices by using different software that takes either Truecolor (RGB) or multispectral images as an input. These maps are then used to segment the crop into management zones. Finally, knowing the spectral signature of a crop (the reflected radiation as a function of wavelength) can be used as an input for decision-making and crop characterization. The calculation of vegetation indices using software such as Pix4D has high precision for monoculture plantations. However, this paper shows that using this software on mixed crops may lead to errors resulting in an incorrect segmentation of the field. Within this work, authors propose to filter all the elements different from the main crop before the calculation of vegetation indices and the spectral signature. A filter based on the Sobel method for border detection is used for filtering a coffee crop. Results show that segmentation into management zones changes with respect to the traditional situation in which a filter is not applied. In particular, it is shown how the values of the spectral signature change in up to 17% per spectral band. Future work will quantify the benefits of filtering through the comparison between in situ measurements and the calculated vegetation indices obtained through remote sensing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coffee" title="coffee">coffee</a>, <a href="https://publications.waset.org/abstracts/search?q=filtering" title=" filtering"> filtering</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20crop" title=" mixed crop"> mixed crop</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20agriculture" title=" precision agriculture"> precision agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20signature" title=" spectral signature"> spectral signature</a> </p> <a href="https://publications.waset.org/abstracts/76629/calculation-of-the-normalized-difference-vegetation-index-and-the-spectral-signature-of-coffee-crops-benefits-of-image-filtering-on-mixed-crops" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76629.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">388</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Vibration Based Damage Detection and Stiffness Reduction of Bridges: Experimental Study on a Small Scale Concrete Bridge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mirco%20Tarozzi">Mirco Tarozzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Giacomo%20Pignagnoli"> Giacomo Pignagnoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Benedetti"> Andrea Benedetti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Structural systems are often subjected to degradation processes due to different kind of phenomena like unexpected loadings, ageing of the materials and fatigue cycles. This is true especially for bridges, in which their safety evaluation is crucial for the purpose of a design of planning maintenance. This paper discusses the experimental evaluation of the stiffness reduction from frequency changes due to uniform damage scenario. For this purpose, a 1:4 scaled bridge has been built in the laboratory of the University of Bologna. It is made of concrete and its cross section is composed by a slab linked to four beams. This concrete deck is 6 m long and 3 m wide, and its natural frequencies have been identified dynamically by exciting it with an impact hammer, a dropping weight, or by walking on it randomly. After that, a set of loading cycles has been applied to this bridge in order to produce a uniformly distributed crack pattern. During the loading phase, either cracking moment and yielding moment has been reached. In order to define the relationship between frequency variation and loss in stiffness, the identification of the natural frequencies of the bridge has been performed, before and after the occurrence of the damage, corresponding to each load step. The behavior of breathing cracks and its effect on the natural frequencies has been taken into account in the analytical calculations. By using a sort of exponential function given from the study of lot of experimental tests in the literature, it has been possible to predict the stiffness reduction through the frequency variation measurements. During the load test also crack opening and middle span vertical displacement has been monitored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20bridge" title="concrete bridge">concrete bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20detection" title=" damage detection"> damage detection</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20test" title=" dynamic test"> dynamic test</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20shifts" title=" frequency shifts"> frequency shifts</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20modal%20analysis" title=" operational modal analysis"> operational modal analysis</a> </p> <a href="https://publications.waset.org/abstracts/99651/vibration-based-damage-detection-and-stiffness-reduction-of-bridges-experimental-study-on-a-small-scale-concrete-bridge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99651.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Antimutagenic Activity of a Protein, Lectin Fraction from Urtica Dioica L.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nijole%20Savickiene">Nijole Savickiene</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonella%20Di%20Sotto"> Antonella Di Sotto</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriela%20Mazzanti"> Gabriela Mazzanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasa%20Starselskyte"> Rasa Starselskyte</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Di%20Giacomo"> Silvia Di Giacomo</a>, <a href="https://publications.waset.org/abstracts/search?q=Annabella%20Vitalone"> Annabella Vitalone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plant lectins are non-enzymic and non-immune origin proteins that specifically recognize and bind to various sugar structures and possess the activity to agglutinate cells and/or precipitate polysaccharides and glycoconjugates. The emerging evidences showed that plant lectins contribute not only to tumour cell recognition but also to cell adhesion and localization, to signal transduction, to mitogenic cytotoxicity and apoptosis. Among chitin-binding lectins, the Urtica dioica agglutinin (UDA), which is a complex of different isoforms, has been poorly studied for its biological activity. In this context and according to the increasing interest for lectins as novel antitumor drugs, present paper aimed at evaluating the potential antimutagenic activity of a lectin-like glycoprotein-enriched fraction from aerial part of Urtica dioica L. Aim: to evaluate the potential chemopreventive properties of a protein - lectin fraction from the aerial part of Urtica dioica. Materials and methods: Protein – lectin fraction has been tested for the antimutagenic activity in bacteria (50–800 mg/plate; Ames test by the preincubation method) and for the cytotoxicity on human hepatoma HepG2 cells (0.06–2 mg/mL; 24 and 48 h incubation). Results: Protein – lectin fraction from stinging nettle was not cytotoxic on HepG2 cells up to 2 mg/mL; conversely, it exhibited a strong antimutagenic activity against the mutagen 2-aminoanthracene (2AA) in all strains tested (maximum inhibition of 56.78 and 61% in TA98, TA100, and WP2uvrA strains, respectively, at 800 mg/plate). Discussion and conclusions: Protein – lectin fraction from Urtica dioica L. possesses antimutagenic and radical scavenging properties. Being 2AA a pro-carcinogenic agent, we hypothesize that the antimutagenicity of it can be due to the inhibition of CYP450-isoenzymes, involved in the mutagen bioactivation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lectins" title="lectins">lectins</a>, <a href="https://publications.waset.org/abstracts/search?q=antimutagenicity" title=" antimutagenicity"> antimutagenicity</a>, <a href="https://publications.waset.org/abstracts/search?q=chemoprevention" title=" chemoprevention"> chemoprevention</a>, <a href="https://publications.waset.org/abstracts/search?q=Urtica%20dioica" title=" Urtica dioica "> Urtica dioica </a> </p> <a href="https://publications.waset.org/abstracts/27253/antimutagenic-activity-of-a-protein-lectin-fraction-from-urtica-dioica-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27253.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">426</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> LAMOS - Layered Amorphous Metal Oxide Gas Sensors: New Interfaces for Gas Sensing Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Paolucci">Valentina Paolucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Jessica%20De%20Santis"> Jessica De Santis</a>, <a href="https://publications.waset.org/abstracts/search?q=Vittorio%20Ricci"> Vittorio Ricci</a>, <a href="https://publications.waset.org/abstracts/search?q=Giacomo%20Giorgi"> Giacomo Giorgi</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlo%20Cantalini"> Carlo Cantalini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite their potential in gas sensing applications, the major drawback of 2D exfoliated metal dichalcogenides (MDs) is that they suffer from spontaneous oxidation in air, showing poor chemical stability under dry/wet conditions even at room temperature, limiting their practical exploitation. The aim of this work is to validate a synthesis strategy allowing microstructural and electrical stabilization of the oxides that inevitably form on the surface of 2D dichalcogenides. Taking advantage of spontaneous oxidation of MDs in air, we report on liquid phase exfoliated 2D-SnSe2 flakes annealed in static air at a temperature below the crystallization temperature of the native a-SnO2 oxide. This process yields a new class of 2D Layered Amorphous Metal Oxides Sensors (LAMOS), specifically few-layered amorphous a-SnO2, showing excellent gas sensing properties. Sensing tests were carried out at low operating temperature (i.e. 100°C) by exposing a-SnO2 to both oxidizing and reducing gases (i.e. NO2, H2S and H2) and different relative humidities ranging from 40% to 80% RH. The formation of stable nanosheets of amorphous a-SnO2 guarantees excellent reproducibility and stability of the response over one year. These results pave the way to new interesting research perspectives out considering the opportunity to synthesize homogeneous amorphous textures with no grain boundaries, no grains, no crystalline planes with different orientations, etc., following gas sensing mechanisms that likely differ from that of traditional crystalline metal oxide sensors. Moreover, the controlled annealing process could likely be extended to a large variety of Transition Metal Dichalcogenides (TMDs) and Metal Chalcogenides (MCs), where sulfur, selenium, or tellurium atoms can be easily displaced by O2 atoms (ΔG < 0), enabling the synthesis of a new family of amorphous interfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=layered%202D%20materials" title="layered 2D materials">layered 2D materials</a>, <a href="https://publications.waset.org/abstracts/search?q=exfoliation" title=" exfoliation"> exfoliation</a>, <a href="https://publications.waset.org/abstracts/search?q=lamos" title=" lamos"> lamos</a>, <a href="https://publications.waset.org/abstracts/search?q=amorphous%20metal%20oxide%20sensors" title=" amorphous metal oxide sensors"> amorphous metal oxide sensors</a> </p> <a href="https://publications.waset.org/abstracts/156610/lamos-layered-amorphous-metal-oxide-gas-sensors-new-interfaces-for-gas-sensing-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156610.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">124</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Hybrid Capture Resolves the Phylogeny of the Pantropically Distributed Zanthoxylum (Rutaceae) and Reveals an Old World Origin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lee%20Ping%20Ang">Lee Ping Ang</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvatore%20Tomasello"> Salvatore Tomasello</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun%20Wen"> Jun Wen</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20S.%20Appelhans"> Marc S.

It is the only genus with a pantropical distribution. Economically, it is used in several Asian countries as traditional medicine and spice. In the past Zanthoxylum was divided into two genera, the temperate Zanthoxylum sensu strictu (s.s.) and the (sub)tropical Fagara, due to the large differences in flower morphology: heterochlamydeous in Fagara and homochlamydeous in Zanthoxylum s.s.. This genus is much under studied and previous phylogenetic studies using Sanger sequencing did not resolve the relationships sufficiently. In this study, we use Hybrid Capture with a specially designed bait set for Zanthoxylum to sequence 347 putatively single-copy genes. The taxon sampling has been largely improved as compared to previous studies and the preliminary results will be based on 371 specimens representing 133 species from all continents and major island groups. Our preliminary results reveal similar tree topology as the previous studies while providing more details to the backbone of the phylogeny. The phylogenetic tree consists of four main clades: A) African/Malagasy clade, B) Z. asiaticum clade - a clade consisting widespread species occurring in (sub)tropical Asia and Africa as well as Madagascar, C) Asian/Pacific clade and D) American clade, which also includes the temperate Asian species. The merging of Fagara and Zanthoxylum is supported by our results and the homochlamydeous flowers of Zanthoxylum s.s. are likely derived from heterochlamydeous flowers. Several of the morphologically defined sections within Zanthoxylum are not monophyletic.

An alternative to reduce the environmental impact of concrete production is to incorporate certain amount of residues in the dosing, limiting the replacement percentages to avoid significant losses in the mechanical properties of the final material. Previous researches demonstrate the feasibility of using brick and rust residues, separately, as a cement replacement. This study analyses the variation in the mechanical properties of mortars by incorporating masonry residue composed of clay bricks and cement mortar. In order to improve the mechanical properties of masonry residue, this was subjected to a heat treatment of 650 ° C for four hours and its effect is analyzed in this study. Masonry residue was obtained from a demolition of masonry perimetral walls. The residues were crushed and sieved and the maximum size of particles used was 75 microns. The percentages of cement replaced by masonry residue were 0%, 10%, 20% and 30%. The effect of masonry residue addition and its heat treatment in the mechanical properties of mortars is evaluated through compressive and flexural strength tests after 7, 14 and 28 curing days. Results show that increasing the amount of masonry residue used increases the losses in compressive strength and flexural strength. However, the use of up to a 20% of masonry residue, when a heat treatment is applied, allows obtaining mortars with similar compressive strength to the control mortar. Masonry residues mortars without a heat treatment show losses in compressive strengths between 15% and 27% with respect to masonry residues with heat treatment, which demonstrates the effectiveness of the heat treatment. From this analysis it can be conclude that it is possible to use up to 20% of masonry residue with heat treatment as cement replacement without significant losses in mortars mechanical properties, reducing considerably the environmental impact of the final material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cement%20replacement" title="cement replacement">cement replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impact" title=" environmental impact"> environmental impact</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry%20residue" title=" masonry residue"> masonry residue</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties%20of%20recycled%20mortars" title=" mechanical properties of recycled mortars"> mechanical properties of recycled mortars</a> </p> <a href="https://publications.waset.org/abstracts/67858/mechanical-properties-analysis-of-masonry-residue-mortar-as-cement-replacement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67858.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Bridge Damage Detection and Stiffness Reduction Using Vibration Data: Experimental Investigation on a Small Scale Steel Bridge </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mirco%20Tarozzi">Mirco Tarozzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Giacomo%20Pignagnoli"> Giacomo Pignagnoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Benedetti"> Andrea Benedetti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The design of planning maintenance of civil structures often requires the evaluation of their level of safety in order to be able to choose which structure, and in which measure, it needs a structural retrofit. This work deals with the evaluation of the stiffness reduction of a scaled steel deck due to the presence of localized damages. The dynamic tests performed on it have shown the variability of its main frequencies linked to the gradual reduction of its rigidity. This deck consists in a steel grillage of four secondary beams and three main beams linked to a concrete slab. This steel deck is 6 m long and 3 m wide and it rests on two abutments made of concrete. By processing the signals of the accelerations due to a random excitation of the deck, the main natural frequencies of this bridge have been extracted. In order to assign more reliable parameters to the numerical model of the deck, some load tests have been performed and the mechanical property of the materials and the supports have been obtained. The two external beams have been cut at one third of their length and the structural strength has been restored by the design of a bolted plate. The gradual loss of the bolts and the plates removal have made the simulation of localized damage possible. In order to define the relationship between frequency variation and loss in stiffness, the identification of its natural frequencies has been performed, before and after the occurrence of the damage, corresponding to each step. The study of the relationship between stiffness losses and frequency shifts has been reported in this paper: the square of the frequency variation due to the presence of the damage is proportional to the ratio between the rigidities. This relationship can be used to quantify the loss in stiffness of a real scale bridge in an efficient way. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage%20detection" title="damage detection">damage detection</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20test" title=" dynamic test"> dynamic test</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20shifts" title=" frequency shifts"> frequency shifts</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20modal%20analysis" title=" operational modal analysis"> operational modal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20bridge" title=" steel bridge"> steel bridge</a> </p> <a href="https://publications.waset.org/abstracts/99649/bridge-damage-detection-and-stiffness-reduction-using-vibration-data-experimental-investigation-on-a-small-scale-steel-bridge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99649.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Deorbiting Performance of Electrodynamic Tethers to Mitigate Space Debris</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giulia%20Sarego">Giulia Sarego</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorenzo%20Olivieri"> Lorenzo Olivieri</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Valmorbida"> Andrea Valmorbida</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlo%20Bettanini"> Carlo Bettanini</a>, <a href="https://publications.waset.org/abstracts/search?q=Giacomo%20Colombatti"> Giacomo Colombatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Pertile"> Marco Pertile</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrico%20C.%20Lorenzini"> Enrico C. Lorenzini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> International guidelines recommend removing any artificial body in Low Earth Orbit (LEO) within 25 years from mission completion. Among disposal strategies, electrodynamic tethers appear to be a promising option for LEO, thanks to the limited storage mass and the minimum interface requirements to the host spacecraft. In particular, recent technological advances make it feasible to deorbit large objects with tether lengths of a few kilometers or less. To further investigate such an innovative passive system, the European Union is currently funding the project E.T.PACK – Electrodynamic Tether Technology for Passive Consumable-less Deorbit Kit in the framework of the H2020 Future Emerging Technologies (FET) Open program. The project focuses on the design of an end of life disposal kit for LEO satellites. This kit aims to deploy a taped tether that can be activated at the spacecraft end of life to perform autonomous deorbit within the international guidelines. In this paper, the orbital performance of the E.T.PACK deorbiting kit is compared to other disposal methods. Besides, the orbital decay prediction is parametrized as a function of spacecraft mass and tether system performance. Different values of length, width, and thickness of the tether will be evaluated for various scenarios (i.e., different initial orbital parameters). The results will be compared to other end-of-life disposal methods with similar allocated resources. The analysis of the more innovative system’s performance with the tape coated with a thermionic material, which has a low work-function (LWT), for which no active component for the cathode is required, will also be briefly discussed. The results show that the electrodynamic tether option can be a competitive and performant solution for satellite disposal compared to other deorbit technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deorbiting%20performance" title="deorbiting performance">deorbiting performance</a>, <a href="https://publications.waset.org/abstracts/search?q=H2020" title=" H2020"> H2020</a>, <a href="https://publications.waset.org/abstracts/search?q=spacecraft%20disposal" title=" spacecraft disposal"> spacecraft disposal</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20electrodynamic%20tethers" title=" space electrodynamic tethers"> space electrodynamic tethers</a> </p> <a href="https://publications.waset.org/abstracts/127281/deorbiting-performance-of-electrodynamic-tethers-to-mitigate-space-debris" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127281.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Effect of Volcanic Ash and Recycled Aggregates in Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Viviana%20Letelier">Viviana Letelier</a>, <a href="https://publications.waset.org/abstracts/search?q=Ester%20Tarela"> Ester Tarela</a>, <a href="https://publications.waset.org/abstracts/search?q=Giacomo%20Moriconi"> Giacomo Moriconi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cement industry is responsible for around a 5% of the CO2 emissions worldwide and considering that concrete is one of the most used materials in construction its total effect is important. An alternative to reduce the environmental impact of concrete production is to incorporate certain amount of residuals in the dosing, limiting the replacement percentages to avoid significant losses in the mechanical properties of the final material. This study analyses the variation in the mechanical properties of structural concretes with recycled aggregates and volcanic ash as cement replacement to test the effect of the simultaneous use of different residuals in the same material. Analyzed concretes are dosed for a compressive strength of 30MPa. The recycled aggregates are obtained from prefabricated pipe debris with a compressive strength of 20MPa. The volcanic ash was obtained from the Ensenada (Chile) area after the Calbuco eruption in April 2015. The percentages of natural course aggregates that are replaced by recycled aggregates are of 0% and 30% and the percentages of cement replaced by volcanic ash are of 0%, 5%, 10% and 15%. The combined effect of both residuals in the mechanical properties of the concrete is evaluated through compressive strength tests after, 28 curing days, flexural strength tests after 28 days, and the elasticity modulus after 28 curing days. Results show that increasing the amount of volcanic ash used increases the losses in compressive strength. However, the use of up to a 5% of volcanic ash allows obtaining concretes with similar compressive strength to the control concrete, whether recycled aggregates are used or not. Furthermore, the pozzolanic reaction that occurs between the amorphous silica and the calcium hydroxide (Ca(OH)2) provokes an increase of a 10% in the compressive strength when a 5% of volcanic ash is combined with a 30% of recycled aggregates. Flexural strength does not show significant changes with neither of the residues. On the other hand, decreases between a 14% and a 25% in the elasticity modulus have been found. Concretes with up to a 30% of recycled aggregates and a 5% of volcanic ash as cement replacement can be produced without significant losses in their mechanical properties, reducing considerably the environmental impact of the final material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength%20of%20recycled%20concrete" title="compressive strength of recycled concrete">compressive strength of recycled concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties%20of%20recycled%20concrete" title=" mechanical properties of recycled concrete"> mechanical properties of recycled concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20aggregates" title=" recycled aggregates"> recycled aggregates</a>, <a href="https://publications.waset.org/abstracts/search?q=volcanic%20ash%20as%20cement%20replacement" title=" volcanic ash as cement replacement"> volcanic ash as cement replacement</a> </p> <a href="https://publications.waset.org/abstracts/56425/effect-of-volcanic-ash-and-recycled-aggregates-in-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56425.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Influence of the Quality of the Recycled Aggregates in Concrete Pavement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Viviana%20Letelier">Viviana Letelier</a>, <a href="https://publications.waset.org/abstracts/search?q=Ester%20Tarela"> Ester Tarela</a>, <a href="https://publications.waset.org/abstracts/search?q=Bianca%20Lopez"> Bianca Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Mu%C3%B1oz"> Pedro Muñoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Giacomo%20%20Moriconi"> Giacomo Moriconi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The environmental impact has become a global concern during the last decades. Several alternatives have been proposed and studied to minimize this impact in different areas. The reuse of aggregates from old concretes to manufacture new ones not only can reduce this impact but is also a way to optimize the resource management. The effect of the origin of the reused aggregates from two different origin materials in recycled concrete pavement is studied here. Using the dosing applied by a pavement company, coarse aggregates in the 6.3-25 mm fraction are replaced by recycled aggregates with two different origins: old concrete pavements with similar origin strength to the one of the control concrete, and precast concrete pipes with smaller strengths than the one of the control concrete. The replacement percentages tested are 30%, 40% and 50% in both cases. The compressive strength tests are performed after 7, 14, 28 and 90 curing days, the flexural strength tests and the elasticity modulus tests after 28 and 90 curing days. Results show that the influence of the quality of the origin concrete in the mechanical properties of recycled concretes is not despicable. Concretes with up to a 50% of recycled aggregates from the concrete pavement have similar compressive strengths to the ones of the control concrete and slightly smaller flexural strengths that, however, in all cases exceed the minimum of 5MPa after 28 curing days stablished by the Chilean regulation for pavement concretes. On the other hand, concretes with recycled aggregates from precast concrete pipes show significantly lower compressive strengths after 28 curing days. The differences with the compressive strength of the control concrete increase with the percentage of replacement, reaching a 13% reduction when 50% of the aggregates are replaced. The flexural strength also suffers significant reductions that increase with the percentage of replacement, only obeying the Chilean regulation when 30% of the aggregates are recycled after 28 curing days. Nevertheless, after 90 curing days, all series obey the regulation requirements. Results show, not only the importance of the quality of the origin concrete, but also the significance of the curing days, that may allow the use of less quality recycled material without important strength losses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength%20of%20recycled%20concrete." title="flexural strength of
