This paper addresses the need to define and discuss the relationship between the digital human model, the human digital twin and the digital twin. Nowadays, in scientific literature, the new terms human digital twin or digital twin are mentioned in different fields of applications, omitting the concept digital human model. However, a model is not the same as a twin. Simultaneously, the question of whether a digital human model can be a digital ...

This article proposes a fast, lightweight and physics-based digital twin to estimate the real-time junction, case and heat sink temperatures of the switching device in a photovoltaic (PV) boost converter. A lookup table approach is used to model the electric behavior while a traditional Cauer approach is used for the thermal model. To extract the thermal resistances of the MOSFET layers and convection, a finite element method (FEM) simulation is ...

Transparency and information exchange are important parts of synchromodality that
contribute to better overview of options when tackling delays, dynamic switching, and handling
of unexpected events that affect delivery lead-times and costs. The most challenging aspect
when making decisions in a complex adaptive dynamic system, is the ever-changing
environment as we introduce more flexibility which may lead to more ...

Designing a production process such as thermoforming for thermoplastic composites might be challenging as it requires material characteristics at high temperatures. Material characterization tests (e.g., bias extension) in the molten state can encounter several difficulties, one of the most important ones is maintaining a uniform temperature distribution on the sample. Accordingly, during this research, a set of thermal tests has been initially ...

This book covers the notion of the digital twin, which has the potential to alter the way systems are governed and manufactured. It also addresses the metaverse as an emerging technology with its roots in literature, cross-platform avatars, and artificial intelligence-oriented cybersecurity issues. The untapped potential of the metaverse and digital twins as enabling technologies for the next-generation industries is emphasized in various ...

Recent years have witnessed the emergence of the fourth industrial revolution (Industry 4.0) era. This direction is propelled by digitization endeavors in various sectors and domains. Cyber-physical systems (CPS) and the Internet of Things (IoT) are the backbone technologies that play prominent roles and are widely utilized for digitization in various disciplines. Digital Twin (DT) technology, which enables designing and building virtual ...

Digital twins, that is, system models that track a specific system instance, enable various new possibilities in the domains of industry 4.0 and Cyber-Physical Systems. At their core, they consist of models and large amounts of data. Those models often abstract away or linearize parts of the system. Thus, to correctly interpret the output data of the digital twin, one must reason about the model's valid operation region. This paper introduces an ...
