Abstract

In response to stringent emission reduction targets imposed by the International Maritime Organization (IMO) and the European Green Deal's Fit for 55 legislation package, the maritime industry has shifted its focus towards decarbonization. While significant attention has been placed on vessels exceeding 5,000 gross tons (GT), emissions from coastal and short sea shipping, amounting to approximately 13% of global shipping transportation and 15% within the European Union (EU), have not received adequate consideration. This abstract introduces the Zero Emission Sea Transporter (ZEST) project, designed to address this issue by developing a zero-emissions multi-purpose catamaran for short sea route

Abstract

In this paper, we present a comprehensive investigation of the challenges of Monocular Visual Simultaneous Localization and Mapping (vSLAM) methods for underwater robots. While significant progress has been made in state estimation methods that utilize visual data in the past decade, most evaluations have been limited to controlled indoor and urban environments, where impressive performance was demonstrated. However, these techniques have not been extensively tested in extremely challenging conditions, such as underwater scenarios where factors such as water and light conditions, robot path, and depth can greatly impact algorithm performance. Hence, our evaluation is conducted in real-world AUV scenarios as well as laboratory settings which provide precise external reference. A focus is laid on understanding the impact of environmental conditions, such as optical properties of the water and illumination scenarios, on the performance of monocular vSLAM methods. To this end, we first show that all methods perform very well in in-air settings and subsequently show the degradation of their performance in challenging underwater environments. The final goal of this study is to identify techniques that can improve accuracy and robustness of SLAM methods in such conditions. To achieve this goal, we investigate the potential of image enhancement techniques to improve the quality of input images used by the SLAM methods, specifically in low visibility and extreme lighting scenarios in scattering media. We present a first evaluation on calibration maneuvers and simple image restoration techniques to determine their ability to enable or enhance the performance of monocular SLAM methods in underwater environments.

Abstract

Modeling virtual agents with behavior style is one factor for personalizing human agent interaction. We propose an efficient yet effective machine learning approach to synthesize gestures driven by prosodic features and text in the style of different speakers including those unseen during training. Our model performs zero shot multimodal style transfer driven by multimodal data from the PATS database containing videos of various speakers. We view style as being pervasive while speaking, it colors the communicative behaviors expressivity while speech content is carried by multimodal signals and text. This disentanglement scheme of content and style allows us to directly infer the style embedding even of speaker whose data are not part of the training phase, without requiring any further training or fine tuning. The first goal of our model is to generate the gestures of a source speaker based on the content of two audio and text modalities. The second goal is to condition the source speaker predicted gestures on the multimodal behavior style embedding of a target speaker. The third goal is to allow zero shot style transfer of speakers unseen during training without retraining the model. Our system consists of: (1) a speaker style encoder network that learns to generate a fixed dimensional speaker embedding style from a target speaker multimodal data and (2) a sequence to sequence synthesis network that synthesizes gestures based on the content of the input modalities of a source speaker and conditioned on the speaker style embedding. We evaluate that our model can synthesize gestures of a source speaker and transfer the knowledge of target speaker style variability to the gesture generation task in a zero shot setup. We convert the 2D gestures to 3D poses and produce 3D animations. We conduct objective and subjective evaluations to validate our approach and compare it with a baseline.

Abstract

A university campus is a complex environment, as it comprises many areas, each with distinctive acoustic characteristics. There are zones where a quiet environment is crucial for work and study, parking lots and internal road networks, as well as vibrant spaces where students and personnel stay during leisure time. Thus, university campuses clearly offer a remarkable opportunity for the evaluation of soundscape analysis tools and the exploration of new methodologies for assessing and mapping soundscapes. In this work, the Fisciano campus of the University of Salerno (Italy) has been depicted as a case study. Specifically, the outcomes of a soundwalk conducted following ISO/TS 12913 standards will be presented, together with data gathered through crowd-sourcing during NoiseCapture parties. The data from NoiseCapture parties have been used to test and validate an innovative methodology based on an inverse distance weighting interpolation to produce soundscapes’ attributes maps, using the mean pleasantness as an example and exploring the relative influence of the maximum distance used to characterize an homogeneous sound environment to build the maps themselves. The results will offer valuable insights into the proposed methodology.

24. Intellectual capital and R&D performance improvement: the case of Italian public universities.

Abstract

This paper aims to develop a model to analyse and improve the performance of R&D activities in Italian public universities through the intellectual capital (IC) perspective. The extant literature includes several models for R&D analysis, but none quantify the link between IC and universities' research activity performance. This research attempts to fill a gap in knowledge by explicitly focusing on the relationship between IC according to its dimensions and universities' research activity performance. To achieve this aim, we develop a theoretical model and test the model using secondary data from all the Italian public universities through the structural equation modelling method. The findings show that small universities with a good level of relations with external organisations, a good level of internationalisation and solid infrastructure have a higher level of scientific productivity than larger universities that are less internationalised and invest less in infrastructure.

Abstract

In the landscape of robotics applications, the pivotal role of occupancy grids in preserving environmental data cannot be overstated. This significance becomes particularly pronounced in the realm of Simultaneous Localization and Mapping (SLAM), where mobile robots dynamically navigate and scan their surroundings. Addressing the challenges posed by loop closure detection, FRAGG-Map—an innovative 3D grid expressly crafted to optimize efficiency during sustained, long-term exploration. Diverging from conventional methods, FRAGG-Map minimizes the necessity for map reconstruction at loop closures, thereby enhancing overall operational efficiency., Peer Reviewed

Abstract

Policymakers, academics, and practitioners are increasingly discussing non-financial reporting (NFR) initiatives, i.e., reporting initiatives that are related to environmental and social matters. The implementation of NFR initiatives in the context of small and medium-sized enterprises (SMEs) is a key topic. Based on a systematic literature review, this article first synthesizes what we know about the mechanisms underlying NFR initiatives implemented by SMEs. A thematic analysis led to the identification and examination of drivers, enabling factors, and challenges for NFR initiatives. Relevant drivers include legitimacy-based motivations, competitive advantage, and stakeholder engagement. Enabling factors include specific guidelines and tools for NFR. Lack of capabilities and lack of standardization are significant challenges. Second, drawing on the thematic analysis and on what we do not know about NFR in the context of SMEs, a novel conceptualization of NFR as a process characterized by three main phases is presented. Last, this article suggests future research opportunities. [ABSTRACT FROM AUTHOR]
