visual scripting approach for structural safety assessment of masonry walls

CURVED AND LAYERED STRUCTURES 2025年第1期12卷

作者： Lasorella, Mariaceleste Percolla, Giulia Pisano, Aurora Angela Fuschi, Paolo Univ Mediterranea Reggio Calabria Dept dAeD Via Univ 25 I-89124 Reggio Di Calabria Italy

A visual scripting approach for limit analysis of masonry walls subjected to out-of-plane loads is proposed. To this aim, within a visual scripting framework, an interactive CAD representation of the structure and of the acting loads, boundary conditions, and restraints is coupled with an optimization algorithm to calculate the collapse load multiplier and visualize the related predicted collapse mechanism. The proposed approach can be useful for practical purposes, indeed it allows us to quickly identify the key factors that influence the structural response and, through the tuning of some input data, can furnish some hints for design purposes. The effectiveness of the promoted tool is verified by application to eight well-known benchmark cases.

Video game engines are used in most modern video games because they simplify and speed up development. In addition, some of the most popular engines, such as Unreal Engine 5 (UE5), also integrate visual scripting tools. visual scripting in UE5, through Blueprints, is a model-driven development approach that replaces text code, like C++, with a visual language of interconnected nodes representing functions and data flows, forming a flowchart-like logic diagram. This approach simplifies game development by abstracting complex code into intuitive, visual models, enabling creators to construct and iterate game components without extensive programming knowledge. Although Blueprint models usually decrease the complexity of implementing components, thus accelerating the development, they might lead to less energy-efficient runtime performance than C++. In this work, we evaluate the energy consumption of three relevant video game components (health system management, inputs processing, and collections operations for an inventory), each implemented with Blueprint models and C++. The results show that the energy consumption per frame when using C++ is up to 48% lower than when using Blueprint models. The combination of artistic and technical profiles in video game developments has favoured the adoption of Blueprint models. However, there is a lack of works analyzing the energy consumption. Until this work, there was no evidence that the success of models for developing video games, like the one under study in this work, was accompanied by a cost in energy consumption for certain situations. Given the huge popularity of video games, this cost in energy might reach up to the equivalent of the energy consumption of 28 million European households.

Virtual reality (VR) has re-emerged as a low-cost, highly accessible consumer product, and training on simulators is rapidly becoming standard in many industrial sectors. However, the available systems are either focusing on gaming context, featuring limited capabilities or they support only content creation of virtual environments without any rapid prototyping and modification. In this project, we propose a code-free, visual scripting platform to replicate gamified training scenarios through rapid prototyping and VR software design patterns. We implemented and compared two authoring tools: a) visual scripting and b) VR editor for the rapid reconstruction of VR training scenarios. Our visual scripting module is capable of generating training applications utilizing a node-based scripting system, whereas the VR editor gives user/developer the ability to customize and populate new VR training scenarios directly from the virtual environment. We also introduce action prototypes, a new software design pattern suitable to replicate behavioral tasks for VR experiences. In addition, we present the training scenegraph architecture as the main model to represent training scenarios on a modular, dynamic and highly adaptive acyclic graph based on a structured educational curriculum. Finally, a user-based evaluation of the proposed solution indicated that users-regardless of their programming expertise-can effectively use the tools to create and modify training scenarios in VR.

The plethora of ubiquitous information devices create smart environments with new ways to interact. Environments such as pervasive classrooms or smart offices provide diverse services and connect a variety of heterogeneous and mostly mobile devices. Besides all the advantages of this seamless communication, it is a complex task to control the information flow within these environments. As an example, the information flow could control that students in a classroom are allowed to share their screen on a projector or the lecturers laptop. For that, we propose PerFlow, a middleware that allows to configure the information flow within a pervasive environment at runtime. The middleware is designed to enable technically unskilled personnel, such as a lecturer in a classroom might be, to define rules about who is able to send what to whom. Therefore, we have implemented a visual scripting tool into PerFlow. Our evaluation shows that PerFlow enforces the information flow within a pervasive environment without noticeable overhead. Further, we demonstrate the usability of the visual scripting tool in a two-stage user study.

Integrating 4D thermal information with BIM for building envelope thermal performance analysis and thermal comfort evaluation in naturally ventilated environments

Thermal performance of the building envelope exerts considerable influence on maintaining indoor environmental conditions. Acquisition of sensor data of a building is essential to ensure the improvement of the indoor thermal environment for the occupants. The environmental sensor technologies together with Building Information Modeling (BIM) are tools for assessing/analyzing the performance of a building. Although BIM has a potential to verify thermal performance by using a BIM database, integrating the surface-heat of building envelopes and sensing data has not been fully explored in the existing BIM. BIM requires tools to enable building professionals to effectively detect the location of thermal defects and analyze the thermal performance and indoor thermal comfort by accommodating environmental information to be used in the analysis process. Therefore, this research presents a novel method for integrating time-stamped 3D thermal data in the BIM. In the proposed method, the BIM model is integrated with spatio-temporal thermal and air temperature data. visual scripting is used for extracting and then mapping spatio-temporal thermal data to a 3D BIM model. The proposed system converts the collected thermal images into numeric surface temperatures, integrates collected environmental data in the BIM, calculates thermal comfort variables, such as mean radiant temperature (MRT), and assesses the thermal comfort level for various locations inside the building. The applicability of the proposed method is validated in a real-world case study. The developed prototype system provides valuable visualization information and statistical data for analyzing thermal performance and assessing the thermal comfort level. (C) 2017 Elsevier Ltd.

Game engines, like Unreal, Unity, and Cryengine, provide cutting edge graphics, sophisticated physics modeling, and integrated audio, greatly simplifying game development. These advanced features are often accessible through visual scripting interfaces used in rapid prototyping and by non-programmers. The goal of this research was to demonstrate that these tools can support implementation of artificial intelligence techniques, such as reinforcement learning, that have the potential to yield dynamic characters that are not preprogrammed, but rather learn their behavior via algorithms. Its novelties are the implementation of a Q-Learning bot, created in Unreal Engine's visual scripting tool, known as Blueprint.

Biocybernetic loops (BLs) are physiological adaptation mechanisms created to augment human-computer interaction by interpreting human behaviour via physiological responses. Because of its inherent complexity, the development of BLs has been mainly utilized within the academic environment, with limited use of physiologically adaptive systems in promising fields such as assistive and gaming technologies. The Biocybernetic Loop Engine (BL Engine) is an integrated software tool designed for an easy creation of physiologically modulated videogames by means of wearable sensors. The BL Engine includes a signal acquisition panel, which facilitates the connectivity of multiple physiological sensors and the processing of their signals, a biocybernetic console to rapidly create and iterate adaptive rules using a visual scripting module, and a game connector tool that ties physiological modulations to game variables. In this paper, we present the BL Engine software architecture, its design and implementation process, as well as a proof-of-concept of the system applied to an exergaming experience aiming to improve cardiorespiratory fitness training in older adults. By developing integrated tools that aid the design and implementation of BLs in videogames, we aim to contribute to the dissemination and widespread use of this approach in the gaming industry and serious gaming applications.
