This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio

JUNO Conceptual Design Report

The Jiangmen Underground Neutrino Observatory (JUNO) is proposed to determine the neutrino mass hierarchy using an underground liquid scintillator detector. It is located 53 km away from both Yangjiang and Taishan Nuclear Power Plants in Guangdong, China. The experimental hall, spanning more than 50 meters, is under a granite mountain of over 700 m overburden. Within six years of running, the detection of reactor antineutrinos can resolve the neutrino mass hierarchy at a confidence level of 3-4$\sigma$, and determine neutrino oscillation parameters $\sin^2\theta_{12}$, $\Delta m^2_{21}$, and $|\Delta m^2_{ee}|$ to an accuracy of better than 1%. The JUNO detector can be also used to study terrestrial and extra-terrestrial neutrinos and new physics beyond the Standard Model. The central detector contains 20,000 tons liquid scintillator with an acrylic sphere of 35 m in diameter. $\sim$17,000 508-mm diameter PMTs with high quantum efficiency provide $\sim$75% optical coverage. The current choice of the liquid scintillator is: linear alkyl benzene (LAB) as the solvent, plus PPO as the scintillation fluor and a wavelength-shifter (Bis-MSB). The number of detected photoelectrons per MeV is larger than 1,100 and the energy resolution is expected to be 3% at 1 MeV. The calibration system is designed to deploy multiple sources to cover the entire energy range of reactor antineutrinos, and to achieve a full-volume position coverage inside the detector. The veto system is used for muon detection, muon induced background study and reduction. It consists of a Water Cherenkov detector and a Top Tracker system. The readout system, the detector control system and the offline system insure efficient and stable data acquisition and processing.Comment: 328 pages, 211 figure

Emerging Informatics

The book on emerging informatics brings together the new concepts and applications that will help define and outline problem solving methods and features in designing business and human systems. It covers international aspects of information systems design in which many relevant technologies are introduced for the welfare of human and business systems. This initiative can be viewed as an emergent area of informatics that helps better conceptualise and design new world-class solutions. The book provides four flexible sections that accommodate total of fourteen chapters. The section specifies learning contexts in emerging fields. Each chapter presents a clear basis through the problem conception and its applicable technological solutions. I hope this will help further exploration of knowledge in the informatics discipline

Development of a BIM-based simulator for workspace management in construction

openNei cantieri edili, quali contesti altamente dinamici, lo spazio richiesto dalle attività muta continuamente evidenziando la necessità di considerarlo come una risorsa limitata. Ad oggi, le aree di lavoro non sono efficacemente gestite né dalle tecniche tradizionali di pianificazione né dagli strumenti 4D più avanzati. I manager del processo costruttivo sono costretti a condurre considerazioni spaziali manualmente sulla base di schizzi 2D. Tale approccio è altamente dispendioso e soggetto ad errori; inoltre, come dimostrano le statistiche, è una delle principali cause di infortuni e riduzione della produttività. Questa tesi di dottorato affronta il problema della gestione delle aree di lavoro, proponendo un approccio che integra la fase di pianificazione con la verifica delle interferenze, condotta da un simulatore spaziale sviluppato in un motore grafico. Tale simulatore, acquisiti il modello BIM ed il cronoprogramma, individua eventuali conflitti spaziali quale risultato di computazioni geometriche e simulazioni fisiche. La criticità dei conflitti viene stimata mediante inferenza Bayesiana al fine di escludere scenari trascurabili. Successivamente, i manager del processo costruttivo, consapevoli dei possibili conflitti spaziali futuri, modificano o confermano il cronoprogramma. Questo approccio può essere applicato per identificare i conflitti spaziali sia durante la fase di pianificazione che quella di esecuzione dei lavori. In questa tesi, il simulatore spaziale proposto è stato validato con riferimento alla fase di pianificazione dei lavori di un edificio reale. I risultati hanno dimostrato la sua capacità di identificare non solo un maggior numero di conflitti, rispetto agli strumenti dello stato dell’arte, ma anche di stimare il relativo livello di criticità evitando sovrastime. In futuro, l’approccio proposto in questa tesi, adattato con minime integrazioni, potrà essere applicato a runtime per aggiornare il cronoprogramma durante l’esecuzione dei lavori.In the AEC industry, construction sites are very dynamic operating environments. Activities workspace demand continuously changes across space demanding and time, stressing the need to consider the space as a limited and renewable resource. This issue has not been fully handled yet, neither by traditional scheduling techniques nor by more advanced 4D tools. For these reasons, construction management teams usually carry out manually spatial considerations based on 2D sketches. This approach, especially in big construction projects, is highly time-demanding and error-prone causing, as demonstrated by statistics, injuries, and productivity slowdown. To cover these gaps, this study proposes a workspace management framework that integrates the work scheduling phase with spatial analysis, carried out by a spatial conflict simulator developed using a serious game engine. The simulator, given the BIM model and the construction work schedule, can detect eventual spatial interferences based on geometric computations and physics simulations. The detected conflicts are then judged applying Bayesian inference to filter non-critical scenarios and avoid overestimation. Afterwards, the construction management team, made aware of likely future spatial issues, can adjust or confirm the work schedule. This approach can provide a valuable contribution in detecting spatial conflicts during both the construction planning phase and works execution. In this study, the proposed spatial conflict simulator has been validated on the planning phase of a real use case, demonstrating its capability to not only detect an increased number of spatial issues, compared to the state-of-the-art tools, but also to esteem related criticality levels and avoid overestimations. In the future, the proposed approach, adapted with minor changes, can be applied at runtime for proactively refining the work schedule during works execution.INGEGNERIA CIVILE, AMBIENTALE, EDILE E ARCHITETTURAopenMessi, Leonard

Current State of Research on Pressurized Water Reactor Safety

For more than 40 years, IPSN then IRSN has conducted research and development on nuclear safety, specifically concerning pressurized water reactors, which are the reactor type used in France. This publication reports on the progress of this research and development in each area of study – loss-of-coolant accidents, core melt accidents, fires and external hazards, component aging, etc. –, the remaining uncertainties and, in some cases, new measures that should be developed to consolidate the safety of today’s reactors and also those of tomorrow. A chapter of this report is also devoted to research into human and organizational factors, and the human and social sciences more generally. All of the work is reviewed in the light of the safety issues raised by feedback from major accidents such as Chernobyl and Fukushima Daiichi, as well as the issues raised by assessments conducted, for example, as part of the ten-year reviews of safety at French nuclear reactors. Finally, through the subjects it discusses, this report illustrates the many partnerships and exchanges forged by IRSN with public, industrial and academic bodies both within Europe and internationally

Fire Safety and Management Awareness

To ensure a healthy lifestyle, fire safety and protocols are essential. The population boom, economic crunches, and excessive exploitation of nature have enhanced the possibilities of destruction due to an event of a fire. Computational simulations enacting case studies and incorporation of fire safety protocols in daily routines can help in avoiding such mishaps
