Abstract
Composites are finding increased use in structural high demanding and high added value applications in advanced industries. A wide diversity exists in terms of matrix type, which can be either polymeric or metallic and type of reinforcements (ceramic, polymeric or metallic). Several technologies have been used to produce these composites; among them, additive manufacturing (AM) is currently being applied. In structural applications, the presence of defects due to fabrication is of major concern, since it affects the performance of a component with negative impact, which can affect, ultimately, human lives. Thus, the detection of defects is highly important, not only surface defects but also barely visible defects. This chapter describes the main types of defects expected in composites produced by AM. The fundamentals of different non-destructive testing (NDT) techniques are briefly discussed, as well as the state of the art of numerical simulation for several NDT techniques. A multiparametric and customized inspection system was developed based on the combination of innovative techniques in modelling and testing. Experimental validation with eddy currents, ultrasounds, X-ray and thermography is presented and analysed, as well as integration of distinctive techniques and 3D scanning characterization. © 2020, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.

Abstract
Nowadays wearable devices are very popular. The reason for that is the sudden reduction in pricing and the increase in functionalities. Healthcare services have been greatly benefiting from the emergence of these devices since they can collect vital signs and help healthcare professionals to easily monitor patients. Medical wellness, prevention, diagnosis, treatment and monitoring services are the main focus of Healthcare applications. Some companies have already invested in this market and we present some of them and their strategies. Furthermore, we also conducted a group interview with Altice Labs in order to better understand the critical points and challenges they encountered while developing and maintaining their service. With the purpose of comprehending users’ receptiveness to mHealth systems (mobile health systems which users wear - wearables) and their opinion about sharing data, we also created a questionnaire (which had 114 valid responses). Based on the research done we propose a different approach. In our product and service concept solution, which we share herein, we consider people of all ages to be targets for the product/service and, beyond that, we consider the use of machine learning techniques to extract knowledge from the information gathered. Finally, we discuss the advantages and drawbacks of this kind of system, showing our critical point of view. © 2020, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.

Abstract
Purpose The purpose of this paper is to identify the antecedents and consequences of social media fashion influencer's (SMFI) diffusion of fashion information. This study proposes and examines following research questions: What motivates SMFI to share fashion information? In what way shared fashion information impact SMFI? Design/methodology/approach This study uses semi-structured interviews with SMFI to learn about their relationships with followers. It then conducts a survey of 510 SMFI in Portugal. The data are analyzed by structural equation modeling. Findings The results indicate that intrinsic motivation can develop a SMFIs' fashion leadership, while the SMFIs' perceived usability of fashion blogs does not. The authors also find a self-serving bias among SMFI. Research limitations/implications SMFIs' fashion leadership is associated with the intrinsic motivations of sharing and helping other consumers make fashion decisions, which indicates that marketers can improve their results through using opinion SMFI to assist fashion consumers in purchasing decisions. Further studies should explore the processes adopted by fashion consumers to evaluate SMFI. Originality/value This study helps to understand the antecedents and consequences of fashion diffusion by SMFIs. In particular, the research helps the marketers to understand how the bonds between SMFIs and followers are nurtured.

Abstract
This paper presents an overview of the design principles behind Digital Music Instruments (DMIs) for education across all editions of the International Conference on New Interfaces for Music Expression (NIME). We compiled a comprehensive catalogue of over hundred DMIs with varying degrees of applicability in the educational practice. Each catalogue entry is annotated according to a proposed taxonomy for DMIs for education, rooted in the mechanics of control, mapping and feedback of an interactive music system, along with the required expertise of target user groups and the instrument learning curve. Global statistics unpack underlying trends and design goals across the chronological period of the NIME conference. In recent years, we note a growing number of DMIs targeting non-experts and with reduced requirements in terms of expertise. Stemming from the identified trends, we discuss future challenges in the design of DMIs for education towards enhanced degrees of variation and unpredictability.

Abstract
This paper addresses Three-Dimensional (3D) reconstruction of historical sites with an Unmanned Aerial Vehicle (UAV), combining the information from a visible spectrum camera with a Light Detection and Ranging (LiDAR). The developed solution was validated in two sites located in Monastery of Tibães (Braga, NW Portugal), within the scope of MineHeritage project, which intends to reach society on the importance of raw materials through a historical approach. The outputs obtained from the datasets, resulted in a successfully 3D reconstruction of the two studied sites on the Monastery. Although the research is still ongoing on this topic, this paper is a starting point and an important contribution to this field and this type of scenarios. © CLAWAR Association Ltd.
