Exploring the confluence of IoT and metaverse: Future opportunities and challenges
The Internet of Things (IoT) and the metaverse are two rapidly evolving technologies that have the potential to shape the future of our digital world. IoT refers to the network of physical devices, vehicles, buildings, and other objects that are connected to the internet and capable of collecting and sharing data. The metaverse, on the other hand, is a virtual world where users can interact with each other and digital objects in real time. In this research paper, we aim to explore the intersection of the IoT and metaverse and the opportunities and challenges that arise from their convergence. We will examine how IoT devices can be integrated into the metaverse to create new and immersive experiences for users. We will also analyse the potential use cases and applications of this technology in various industries such as healthcare, education, and entertainment. Additionally, we will discuss the privacy, security, and ethical concerns that arise from the use of IoT devices in the metaverse. A survey is conducted through a combination of a literature review and a case study analysis. This review will provide insights into the potential impact of IoT and metaverse on society and inform the development of future technologies in this field
Development of an open access system for remote operation of robotic manipulators
Mestrado de dupla diplomação com a UTFPR - Universidade Tecnológica Federal do ParanáExploring the realms of research, training, and learning in the field of robotic systems poses obstacles for institutions lacking the necessary infrastructure. The significant investment required to acquire physical robotic systems often limits access and hinders progress in these areas. While robotic simulation platforms provide a virtual environment for experimentation, the potential of remote robotic environments surpasses this by enabling users to interact with real robotic systems during training and research activities. This way, users, including students and researchers, can engage in a virtual experience that transcends geographical boundaries, connecting them to real-world robotic systems though the Internet. By bridging the gap between virtual and physical worlds, remote environments offer a more practical and immersive experience, and open up new horizons for collaborative research and training. Democratizing access to these technologies means
empower educational institutions and research centers to engage in practical and handson learning experiences. However, the implementation of remote robotic environments comes with its own set of technical challenges: communication, security, stability and access. In light of these challenges, a ROS-based system has been developed, providing open access with promising results (low delay and run-time visualization). This system enables remote control of robotic manipulators and has been successfully validated through the
remote operation of a real UR3 manipulator.Explorar as áreas de pesquisa, treinamento e aprendizado no campo de sistemas robóticos apresenta obstáculos para instituições que não possuem a infraestrutura necessária. O investimento significativo exigido para adquirir sistemas robóticos físicos muitas vezes limita o acesso e dificulta o progresso nessas áreas. Embora as plataformas de simulação robótica forneçam um ambiente virtual para experimentação, o potencial dos ambientes robóticos remotos vai além disso, permitindo que os usuários interajam com sistemas robóticos reais durante atividades de treinamento e pesquisa. Dessa forma, os usuários, incluindo estudantes e pesquisadores, podem participar de uma experiência virtual que transcende as fronteiras geográficas, conectando-os a sistemas robóticos do mundo real por meio da Internet. Ao estabelecer uma ponte entre os mundos virtual e físico, os ambientes remotos oferecem uma experiência mais prática e imersiva, abrindo novos horizontes para a pesquisa colaborativa e o treinamento. Democratizar o acesso a essas tecnologias significa capacitar instituições educacionais e centros de pesquisa a se envolverem em experiências práticas e de aprendizado prático. No entanto, a implementação de ambientes robóticos
remotos traz consigo um conjunto próprio de desafios técnicos: comunicação, segurança, estabilidade e acesso. Diante desses desafios, foi desenvolvida uma plataforma baseada em ROS, oferecendo acesso aberto com resultados promissores (baixo delay e visualização em run-time). Essa plataforma possibilita o controle remoto de manipuladores robóticos e foi validada com sucesso por meio da operação remota de um manipulador UR3 real

Exploring psychological interventions and packages of care received by young people with mental health difficulties: A systematic review and longitudinal study
Background
Worsening youth mental health is an increasing concern worldwide, prompting efforts to find efficacious interventions and care packages to support rapidly increasing prevalence rates of mental health difficulties. The systematic review investigated the efficacy of online mindfulness-based interventions (MBIs) for anxiety in young people. The empirical project explored variations in packages of care received by young people accessing mental health services. Both papers sought to inform discussions around helpful models of care for young people and explore possible ways forward for youth mental health care.
Method
The systematic review meta-analysed 14 peer-reviewed studies of online MBIs for youth with self-reported symptoms of anxiety. The empirical study was a secondary analysis of an existing dataset, exploring the mental health care received by 222 young people with clinically severe and complex mental health difficulties and social disability.
Results
The systematic review showed small effects in the direction of the reduction of anxiety symptomology following a course of online MBI. The empirical study showed that young people with more severe difficulties at baseline received more complex care, but that outcomes were comparable across different care packages.
Conclusions
Findings from both the systematic review and empirical project provide tentative support for the need for flexible, transdiagnostic approaches to youth mental health care. Findings from the systematic review suggest online MBIs may be an affordable, accessible and scalable option for milder presentations of anxiety in young people in the absence of an alternative intervention. The empirical project highlights that young people with more complex presentations require more care but that a specific model does not necessarily translate into better functional outcomes. Both papers highlight the need for youth mental health care to be considered along a continuum, with support provided based on individual stage of development and impairment
Planejamento de caminhos 3D em ambiente estático
Orientador: André Luiz Pires GuedesTese (doutorado) - Universidade Federal do Paraná, Setor de Ciências Exatas, Programa de Pós-Graduação em Informática. Defesa : Curitiba, 03/05/2023Inclui referênciasÁrea de concentração: Ciência da ComputaçãoResumo: O Planejamento de caminhos no R3 é um problema computacional que tem despertado o interesse dos pesquisadores por sua vasta aplicabilidade em otimização. Dados um ambiente 3D com obstáculos, um ponto origem e um ponto destino, a resposta esperada é se existe algum caminho, livre de obstáculos, entre origem e destino e havendo, qual dos caminhos minimiza custo. Este problema pertence à classe de complexidade computacional NP-Difícil. A presente pesquisa se propõe a estudar este problema e propor técnicas que permitam obter o caminho mínimo em tempo computacional razoável. A pesquisa consiste em elaborar algoritmos, propor otimizações, analisar seus desempenhos e qualidade dos seus resultados na intenção de, pelo menos, se aproximar do ótimo em tempo polinomial. Apesar de se vislumbrar inúmeras aplicações práticas, a pesquisa se atém apenas a propor variações do algoritmo planejador que recebe dados do ambiente e retorna um caminho a ser seguido, ignorando como os dados de entrada foram obtidos e como os dados de saída se converterão em ações posteriormente. Este trabalho propõe com otimizações simples que em teoria reduzem drasticamente o custo computacional para este problema no caso geral.Abstract: Path planning inR3 is a computational problem that has aroused the interest of researchers due to its wide applicability in optimization. Given a 3D environment with obstacles, a source point and a target point, the expected answer is whether there is a path, free of obstacles, between source and target and if so, which path minimizes cost. This problem belongs to the NP-Hard computational complexity class. This research proposes to study this problem and propose techniques that allow obtaining the shortest path in reasonable computational time. The research consists of developing algorithms, proposing optimizations, analyzing their performance and the quality of their results with the intention of at least approaching the optimum in polynomial time. Despite envisioning numerous practical applications, the research just sticks to proposing variations of the planner algorithm that receives data from the environment and returns a path to be followed, ignoring how the input data were obtained and how the output data will be converted into actions posteriorly. This work proposes simple optimizations that in theory drastically reduce the computational cost for this problem in the general case
CityGML in the Integration of BIM and the GIS: Challenges and Opportunities
CityGML (City Geography Markup Language) is the most investigated standard in the integration of building information modeling (BIM) and the geographic information system (GIS), and it is essential for digital twin and smart city applications. The new CityGML 3.0 has been released for a while, but it is still not clear whether its new features bring new challenges or opportunities to this research topic. Therefore, the aim of this study is to understand the state of the art of CityGML in BIM/GIS integration and to investigate the potential influence of CityGML3.0 on BIM/GIS integration. To achieve this aim, this study used a systematic literature review approach. In total, 136 papers from Web of Science (WoS) and Scopus were collected, reviewed, and analyzed. The main findings of this review are as follows: (1) There are several challenging problems in the IFC-to-CityGML conversion, including LoD (Level of Detail) mapping, solid-to-surface conversion, and semantic mapping. (2) The ‘space’ concept and the new LoD concept in CityGML 3.0 can bring new opportunities to LoD mapping and solid-to-surface conversion. (3) The Versioning module and the Dynamizer module can add dynamic semantics to the CityGML. (4) Graph techniques and scan-to-BIM offer new perspectives for facilitating the use of CityG
Epsilon Futuristic Virtual User Environment
Virtual Reality (VR) is an essential technology in
today’s internet world. VR has the capability to provide great insight into a particular subject, display features of a device, or even convey an idea through its exceptionally realistic atmosphere. Epsilon represents an advanced skin measurement device. It was initially built as part of a research project by a team at London South Bank University. Currently, Epsilon has been introduced and applied in several global corporations. The futuristic concept of Epsilon was an essential part of upgrading this medical research tool. However, comprehensive training that involves being physically present on campus is essential for Epsilon and requires significant time and money. Consequently, utilising the Virtual User Environment (VUE) to showcase all
features of the futuristic Epsilon device is an essential step to demonstrating its qualities by providing users with the necessary training. This paper outlines the process of creating a web-based, interactive 3D virtual user environment for the futuristic Epsilon device. The VUE is an interactive 3D guide that will display to all learners all the futuristic features of Epsilon. Furthermore, enhancing the functionality of this device is a crucial element of effectively marketing this research instrument globally
