Thermal anomalies detection in a photovoltaic plant using artificial intelligence: Italy case studies
2021
This paper proposes the application of artificial intelligence techniques for the identification of thermal anomalies that occur in a photovoltaic system due to malfunctions or faults, with the aim to limit the energy production losses by detecting faults at an early stage. The proposed approach is based on a Thermographic Non-Destructive Test conducted with Unmanned Aerial Vehicles equipped with a thermal imaging camera, which allows the detection of abnormal operating conditions without interrupting the normal operation of the PV system rapidly and cost-effectively. The thermographic images and videos are automatically inspected using a Convolutional Neural Network, developed by an open-s…
Interactive Tools for the Preservation, Dissemination and Study of Silk Heritage—An Introduction to the SILKNOW Project
2018
Silk was a major factor for progress in Europe, mostly along the Western Silk Road’s network of production and market centers. The silk trade also allowed for the exchange of ideas and innovations, having impacts at economic, technical, functional, cultural and symbolic levels. However, silk has today become a seriously endangered heritage. Although many European specialized museums are devoted to its preservation, they usually lack the size and resources to take advantage of state-of-the-art digital technologies. The aim of this paper is twofold; firstly, we introduce SILKNOW, an interdisciplinary project that has been recently funded by the H2020 Programme of the European Union in order t…
Path-dependencies, constrained transformations and dynamic agency. An accounting case study informed by both ANT and NIS
2013
Purpose – The purpose of this paper is to discuss the compatibility of actor network theory (ANT) and new institutional sociology (NIS) in analysing a case study of accounting change. Design/methodology/approach – This is an interpretive case study. Findings – The Finnish case city experienced several path-dependent changes concerning performance measurement (PM), financial reporting and the adoption of enterprise resource planning system (ERP). New tools such as the ERP have a potential to transform the actors and to change the agency of the actors. Furthermore, the concepts drawing on both ANT and NIS can together enrich analyses of accounting changes. Research limitations/implications – …
Trouble in Paradise: a Case of a Technology Industry Supply Network
2009
The development of value networks is regarded as a necessity for achieving agility in global markets. Nowadays the focal companies often state that they are committing to more in-depth partnerships with selected suppliers, which are given more responsibility over both production and R&D. In this article we study the relationship of one focal company with its suppliers and identify the main concerns regarding governance and cooperation within the studied supply network in relation with the focal company’s strategy to enhance its innovative capabilities and ensure capacity in its supplier network. By analyzing the network relationships from three differing vantage points (the focal company, t…
Anonymization as homeomorphic data space transformation for privacy-preserving deep learning
2021
Industry 4.0 is largely data-driven nowadays. Owners of the data, on the one hand, want to get added value from the data by using remote artificial intelligence tools as services, on the other hand, they concern on privacy of their data within external premises. Ideal solution for this challenge would be such anonymization of the data, which makes the data safe in remote servers and, at the same time, leaves the opportunity for the machine learning algorithms to capture useful patterns from the data. In this paper, we take the problem of supervised machine learning with deep feedforward neural nets and provide an anonymization algorithm (based on the homeomorphic data space transformation),…

Tourism destination and the role of trust
2012
Tourism destinations increasingly pose new challenges to the organizational and management aspects of tourism. The non-cooperative behavior of some companies, the difficulties of sharing a system of values, the absence or inadequacy of destination managers keep some destinations off the map of growth that is sought for by the stakeholders and shareholders of a given resort. This difficulty seems to lie in the scarce knowledge of the system of relations existing between firms and their degree of cooperation. The application of Social Network Analysis (SNA) and some indicators for network analysis provides a clearer and more analytical map of the links between tourism businesses located withi…
Destinazione turistica e networks interni ed esterni: il turismo relazionale
2022
The limitation in the relations between people caused by the pandemic today pushes more and more travellers in search of experiences and interactions with the territories, especially those excluded from the current production processes and the dominant market logic. In this context, the tourism of the roots or return tourism is motivated by a need to rediscover their origins, discover them, or trace them in places related to the history of travellers or their families. We, therefore, describe the main dimensions of the relationship tourism model so that it can be applied to root tourism.
Are customer star ratings and sentiments aligned? A deep learning study of the customer service experience in tourism destinations
2023
AbstractThis study explores the consistency between star ratings and sentiments expressed in online reviews and how they relate to the different components of the customer experience. We combine deep learning applied to natural language processing, machine learning and artificial neural networks to identify how the positive and negative components of 20,954 online reviews posted on TripAdvisor about tourism attractions in Venice impact on their overall polarity and star ratings. Our findings showed that sentiment valence is aligned with star ratings. A cancel-out effect operates between the positive and negative sentiments linked to the service experience dimensions in mixed-neutral reviews.
Tourism Destination Brokers: a network analytic approach
2022
Understanding the interactions of tourist companies could be relevant for the destination’s organisation and management. The present article employs a network analysis to examine inter-organisational interactions and the various roles that some companies assume in tourism destinations. The results reveal the existence of a network in which enterprises, identified as brokers, take on strategic roles both within and outside of their specific sub-sectors of origin. This study proposes new social network analysis indicators to identify the distinctive and prevalent position of company brokers, who manage inter-organisational relations by spontaneously assuming specific roles within the tourist …
