Abstract
FluidHarmony is an algorithmic method for defining a hierarchical harmonic lexicon in equal temperaments. It utilizes an enharmonic weighted Fourier transform space to represent pitch class set (pcsets) relations. The method ranks pcsets based on user-defined constraints: the importance of interval classes (ICs) and a reference pcset. Evaluation of 5,184 Western musical pieces from the 16th to 20th centuries shows FluidHarmony captures 8% of the corpus's harmony in its top pcsets. This highlights the role of ICs and a reference pcset in regulating harmony in Western tonal music while enabling systematic approaches to define hierarchies and establish metrics beyond 12-TET.

Abstract
Virtual reality (VR) technologies have been used successfully in tourism marketing. While most conventional VR applications are of an audiovisual nature, the constant evolution of these technologies allows providing enriched multisensory VR content that can further increase the potential of VR applied to the tourism field. To generate insights into the impact of such VR technologies, this manuscript investigates the impact of such multisensory VR setups and gender on the user's sense of presence, satisfaction, emotions, and attitudes. A user study with a gender-balanced sample (N = 80) was carried where two VR setups (audiovisual vs multisensory) were compared taking into account the user's gender. Results revealed that the female sample scored significantly higher spatial presence across VR setups and reported more involvement and overall presence in the audiovisual condition. In addition, correlations were found between the pairs Spatial Presence-Emotions, Spatial Presence-Enjoyment, Satisfaction-Involvement, Satisfaction-Enjoyment, and Satisfaction and Usefulness to perceive the destination. Results also suggest that multisensory stimulus can mitigate possible gender differences in passive VR scenarios. We concluded that the capability of the VR system to make users feel physically present in the virtual environment contributes significantly to the development of positive emotions and enjoyment, which can contribute positively to the user's consumer behaviour towards the touristic products and services.

Abstract
As blockchains go beyond cryptocurrencies into applications in multiple industries such as Insurance, Healthcare and Banking, handling personal or sensitive data, data access control becomes increasingly relevant. Access control mechanisms proposed so far are mostly based on requester identity, particularly for permissioned blockchain platforms, and are limited to binary, all-or-nothing access decisions. This is the case with Hyperledger Fabric's native access control mechanisms and, as permission updates require consensus, these fall short regarding the flexibility required to address GDPR-derived policies and client consent management. We propose SDAM, a novel access control mechanism for Fabric that enables fine-grained and dynamic control policies, using both contextual and resource attributes for decisions. Instead of binary results, decisions may also include mandatory data transformations as to conform with the expressed policy, all without modifications to Fabric. Results show that SDAM's overhead w.r.t baseline Fabric is acceptable. The scalability of the approach w.r.t to the number of concurrent clients is also evaluated and found to follow Fabric's.

Abstract
Forests are remote areas with uneven terrain, so it is costly to map the range of signals that enable the implementation of systems based on wireless and long-distance communication. Even so, the interest in Internet of Things (IoT) functionalities for forest monitoring systems has increasingly attracted the attention of several researchers. This work demonstrates the development of a platform that uses the GPS technology of mobile devices to map the signals of a LoRaWAN Gateway. Therefore, the proposed system is based on concatenating two messages to optimize the LoRaWAN transmission using the Global Position System (GPS) data from a mobile device. With the proposed approach, it is possible to guarantee the data transmission when finding the ideal places to fix nodes regarding the coverage of LoRaWAN because the Gateway bandwidth will not be fulfilled. The tests indicate that different changes in the relief and large bodies drastically affect the signal provided by the Gateway. This work demonstrates that mapping the Gateway's signal is essential to attach modules in the forest, agriculture zones, or even smart cities.

Abstract
This article investigates the use of a high-frequency link in a topology with two three-leg series-connected single-phase to three-phase ac-dc-ac converters. The paper discusses the system model, pulse width modulation (PWM) technique, control system, and high-frequency link design. The studied topology is compared with the conventional one regarding the operating point specification, and the control system's complexity, among other characteristics. Simulation and experimental results are provided for validation and illustration of converter operations. © 2022 IEEE.
