Abstract
Materials represented by measured BRDF (Bidirectional Reflectance Distribution function) with reflectance data captured from real-world materials have become increasingly prevalent due to the development of novel measurement approaches. Nowadays, important limitations can be highlighted in the current material scanning process, mostly related to the high diversity of existing materials in the real-world and the tedious process for material scanning. Consequently, new approaches are required both for the automatic material acquisition process and for the generation of measured material databases. In this study, a novel approach is proposed for modelling the material appearance by sampling hyperspectral measurements on the BRDF domain. An unmanned aerial vehicle (UAV)-based hyperspectral sensor was used to capture high spatial and spectral resolution data. The generated hyperspectral data cubes were used to identify materials with a similar spectral behaviour. Then, a sparse mapping of collected samples is developed to study the appearance of natural and artificial materials in an urban scenario. © 2021 IEEE.

Abstract
The Real-Time Monitoring and Performance Management suite tool, known as UIL (User Interface Layer), was developed in the FASTEN project, a R&D initiative financed by the innovation and research program H2020 within a bilateral Europe-Brazil call. UIL was conceived and deployed in the IIoT architecture of the project. The goal was to provide a usercentered assistance to the human operator for both decision-responsibility and control loop, in a continuously updating information fashion, related to system's state. In order to have experimental results, a qualitative assessment was conducted in an industrial environment. The architecture proposed was based on the adoption of a Knowledge Engineering User Interface to support Operator 4.0. Our empirical experiments point out to a successful set of results.

Abstract
To identify the most frequently developed topics in the area of Big Data and Digital Marketing, a quantitative analysis was developed in December 2020. This analysis was focused on 750 publications and later on 67 publications on Big Data and Digital Marketing from the Scopus database. A bibliometric analysis was developed using the VOSviewer software and the technique of term co-occurrence and author co-authorship. Clusters were found for each of the analyzed situations. © 2021 AISTI.

Abstract
The need for organizations to cooperate, especially SMEs, is currently considered an appropriate way to gain competitive capacity, and ICT are an enabler to support the creation of interorganizational cooperation networks. However, in rural regions, investment in technology is scarce and often seen as an unbearable cost. In order to respond to this reality, this work presents a conceptual technological model capable of leveraging and supporting the creation of cooperation networks, with the contextualization of the business in rural regions being previously done, exploring the fundamentals of cloud computing and cooperation networks.

Abstract
The Internet of Things has revolutionized the way we can think about sales and customer relationship management strategies. In this context, a view of the world where technology is embedded in practically all objects and physical spaces will be an expectable reality. This reality opens up unprecedented opportunities with regard to the levels of customization in the sales process, whether in virtual spaces or in physical spaces. However, IoT also poses enormous challenges in the field of security and in particular in the field of user privacy. In this context, this article, after analyzing some of the main challenges for IoT in the privacy domain and what impact the IoT may have in the business domain and in particular in the subdomains of sales and advertising, presents a conceptual model to support customer empowerment while citizen with regard to the definition and management of privacy policies concerns a context that may go beyond the boundaries of citizenship and be applied in scenarios without borders, whenever there is the possibility of defining policies and legislation above Country. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
