We present a pilot study where spectral unmixing is applied to hyperspectral images captured in a controlled environment with a threefold purpose in mind: validation of our experimental setup, of the data processing pipeline, and of the usage of spectral unmixing algorithms for the aforementioned research avenue. Results from this study show that classical techniques such as VCA and FCLS can be used to distinguish between plastic and nonplastic materials, but struggle significantly to distinguish between spectrally similar plastics, even in the presence of multiple pure pixels.

This paper explores the potential use of acoustic imaging and the use of a multi-frequency multibeam-echosounder (MBES) for monitoring marine litter in the water column. The main goal is to perform a test and validation setup using a simulation and actual experimental setup to determine if the MBES data can detect marine litter in a water column image (WCI) and if using multi-frequency MBES data will allow to better distinguish and characterize marine litter debris in detection applications. Results using simulated HoloOcean Environment and actual marine litter data revealed the successful detection of objects commonly found in ocean litter hotspots at various ranges and frequencies, enablingthe pursue of novel means of automatic detection and classification in MBES WCI data while using multi-frequency capabilities.

Carbon dioxide (CO2) holds paramount significance in nature, serving as a vital component in Earth's ecosystems. Its evaluation has become increasingly important across various sectors, spanning from environmental conservation to industrial operations. Therefore, this study investigates the viability of utilizing a $\mathbf{pH}$ colorimetric dye as a C02-sensitive material. The material's effectiveness relies on chemical modifications induced in the dye structure through the action of a phase transfer agent, which establishes a stable equilibrium with the dye, thereby promoting its receptivity to C02 molecules. As the resulting physicochemical changes primarily exhibit colorimetric alterations, an optical system was developed to assess the performance of this material upon exposure to C02. Employing a dual-wavelength method, the system also incorporates a ratio metric relationship between the two signals to provide the most precise information. The conducted experiments generated promising results when the dye was subjected to varying concentrations of C02, ranging from 0% to 4 %, in comparison to nitrogen (N2). The application of the ratiometric method emerged as a crucial factor in this system, enabling its potential use in environments characterized by instability. Finally, the dye-sensitive characteristics experienced enhancement through the integration of an ionic liquid within the membrane matrix.

New systems with innovative design to perform measurements combining electrochemistry and surface plasmon resonance (ESPR) are currently a need to overcome the limitations of existent market solutions and expand the research possibilities of this technology. The main goal of this work was to develop a new cell to increase ESPR practical applications in several fields. To do so, a homemade SPR cell, fabricated by 3D-printing technology, was adapted for this purpose by incorporating the conventional 3-electrodes to perform the electrochemical experiments. The developed cell was fully compatible with commercial SPR substrates. After optimization of the homemade ESPR setup to perform the combined electrochemical and SPR measurements, two main applications were explored in this work. The first was the use of ESPR technology as straightforward tool to simultaneously investigate the electrical and optical properties of conducing/non-conducting polymers electrosynthetized on the SPR platforms. The conducting polymer poly(thionine) was used in this work for proof-of-concept. The second application envisaged the use of ESPR approach for simple electrodeposition ofmaterials with enhanced plasmonic properties for sensitivity enhancement of SPR biosensors. For validation of the concept, graphene oxide (GO) was electrochemically reduced on gold substrates aiming to evaluate the plasmonic properties of graphene-modified sensing surfaces.

Methodological insights from unmanned system technologies in a rock quarry environment and geomining heritage site: coupling LiDAR-based mapping and GIS geovisualisation techniques

作者： Pires, Ana Dias, André Silva, Pedro Ferreira, António Rodrigues, Paulo Santos, Tiago Oliveira, Alexandre Freitas, Liliana Martins, Alfredo Almeida, José Silva, Eduardo Chaminé, Helder I. INESCTEC - Institute for Systems and Computer Engineering Technology and Science Porto Portugal Laboratory of Autonomous Systems Department of Electrotechnical Engineering School of Engineering (ISEP) Polytechnic of Porto Porto Portugal Laboratory of Cartography and Applied Geology (Labcarga) Department of Geotechnical Engineering School of Engineering (ISEP) Polytechnic of Porto Porto Portugal Centre GeoBioTec|UA Aveiro Portugal

The main goal of the research is to present a methodological approach based on geotechnologies to acquire, process and analyse high-resolution 3D data to support georesources monitoring and geoheritage site preservation. The work is focused on the unmanned aerial vehicle (UAV) mapping technology with applications in a challenging framework, i.e. rock quarry and geomining heritage sites. The investigation interconnects several ground fields: engineering geosciences, rock engineering, sensing and aerial technology, and data processing systems for acquiring high-resolution imagery. The study couples two technologies: (1) robotic systems and (2) LiDAR-based mapping and GIS geovisualisation techniques. The approach presented herein shows the complementarity between techniques to improve the rock quarry’s geotechnical assessment and geomining heritage site. It was also possible to operate 3D recording technologies to preserve and record ancient mines’ cultural heritage and surroundings. The methodology shows a common ground for an integrated vision for rocky georesources monitoring by applying UAV mapping technologies. The final outputs allowed the image processing, geospatial analysis and 3D ground modelling of the ‘Malaposta’ gneiss quarry (Lourosa) and the Roman mine ‘Fojo das Pombas’ (Valongo), both sites in NW Portugal.

Multiple perspectives of spiritual intelligence: A systematic literature review

This paper aims to understand the influence of sociocultural perspectives on the perception and conceptualization of spiritual intelligence (SI). To do so, a systematic literature review was carried out, and 64 journal articles and reviews form the sample for data analysis. Four different perspectives (Western, Eastern, Islamic, and Hindu) were identified. In the Western perspective, an egocentric and utilitarian approach to the construct prevails. In the Islamic perspective, religion is understood as the only possible expression of SI. In the Eastern perspective, the point of view of the common good and the connection with nature prevails. In the Hindu perspective, however, knowledge is the key to expanding spiritual awareness. The results indicate that the authors' perspective interferes in the understanding of the conceptualization of SI and its dimensions, and in the interpretation of the research results. Finally, a framework for analyzing SI research is proposed. © 2024 The Authors
