Progeny: A Grasshopper Plug-In That Augments Cellular Automata Algorithms For 3d Form Explorations, İnanç Şencan Mar 2023

Progeny: A Grasshopper Plug-In That Augments Cellular Automata Algorithms For 3d Form Explorations, İnanç Şencan

Architecture and Planning Journal (APJ)

Cellular automata (CA) is a well-known computation method introduced by John von Neumann and Stanislaw Ulam in the 1940s. Since then, it has been studied in various fields such as computer science, biology, physics, chemistry, and art. The Classic CA algorithm is a calculation of a grid of cells' binary states based on neighboring cells and a set of rules. With the variation of these parameters, the CA algorithm has evolved into alternative versions such as 3D CA, Multiple neighborhood CA, Multiple rules CA, and Stochastic CA (Url-1). As a rule-based generative algorithm, CA has been used as a bottom-up …

Towards Informed Design Decision Support Of Additive Manufacturing In Construction - The Use Of Integrated Knowledge In Bim-Based Architectural Design, Chao Li, Frank Petzold Mar 2023

Towards Informed Design Decision Support Of Additive Manufacturing In Construction - The Use Of Integrated Knowledge In Bim-Based Architectural Design, Chao Li, Frank Petzold

Architecture and Planning Journal (APJ)

Additive Manufacturing (AM) technologies have great potential to promote sustainable development in the architecture, engineering, and construction (AEC) domain. But the inherent complexity of AM and lack of domain knowledge hinder decisions about appropriate construction methods. With state-of-the-art Semantic Web technologies, a knowledge base regarding AM technologies can be formalized and integrated into the Building Information Modeling (BIM) methodology. To this end, this paper demonstrates how a Design Decision Support System (DDSS) utilizes formal knowledge to assist architects in choosing the appropriate AM method by assessing the manufacturability of individual building components.

Getting A Handle On Floor Plan Analysis - Door Classification In Floor Plans And A Survey On Existing Datasets, João David, António Leitão Mar 2023

Getting A Handle On Floor Plan Analysis - Door Classification In Floor Plans And A Survey On Existing Datasets, João David, António Leitão

Architecture and Planning Journal (APJ)

Floor plan interpretation and reconstruction is crucial to enable the transformation of drawings to 3D models or different digital formats. It has recently taken advantage of neural-based architectures, especially in the semantic segmentation field. These techniques perform better than traditional methods, but the results depend mainly on the data used to train the networks, which is often crafted for the specific task being performed, making it hard to reuse for different purposes. In this paper, we conduct a literature survey on the existing datasets for floor plan analysis, and we explore how information regarding door placement and orientation can be …

Architectural Hybrid (Physical-Digital) Prototyping In Design Processes With Digital Twin Technologies, Gulbahar Emir Isik, Henri Achten

Architecture and Planning Journal (APJ)

A digital twin is a simultaneous digital reflection of object processes and states. Digital twins are usually made of objects that exist in reality or which are very near completion in a design and production process. In our research, we investigate the potential of digital twin technology for early design. Key to the early application of digital twin in design is the role of information and simulation. Since design information is valuable for predicting the future of design, we assume that design will begin to change as digital twin technologies become more and more adaptable, as designers simultaneously have digital …

Gestural Design - Hand Tracking For Digital Drawing, Jordan A. Kanter, Kamil Quinteros Mar 2023

Gestural Design - Hand Tracking For Digital Drawing, Jordan A. Kanter, Kamil Quinteros

Architecture and Planning Journal (APJ)

Computational design is increasingly interested in the active feedback between the user/designer and the digital space. Often, our initial instinct as designers comes from a gesture, a movement of the hands that gets translated into sketches and 3D models via the tools available to us. While the physical realm allows for muscle memory, tactile feedback, and creative output via movement, digital design often negates the body of the designer as it sequesters us into a screen-mouse-hand relationship. Moreover, current CAD software tools often reinforce this standardization, further limiting the potential of physical bodily gestures as a vehicle for architectural form-making. …

Research On Aquifer Water Abundance Evaluation By Borehole Transient Electromagnetic Method Based On Fcnn, Cheng Jiulong, Wang Huijie, Xu Zhongzhong, Huang Qisong, Jiang Guoqing

Coal Geology & Exploration

Predicting the location and water abundance of aquifers by drilling or geophysical methods before tunneling is very important to prevent water disasters in advance for the safety of coal mine production. The use of borehole transient electromagnetic method (BTEM) for advanced detection has obvious advantages. At present, the interpretation method is based on the calculated resistivity to qualitatively analyze rock water abundance, and it is impossible to predict the aquifer water abundance grade. So, the fully convolutional neural network (FCNN) method is proposed to predict the aquifer water abundance grade for BTEM. Firstly, according to the Archie formula, Kozeny-Carman formula, …

Challenges And Solutions To High-Resolution Data Processing For Seismic Exploration, Cao Siyuan, Sun Yaoguang, Chen Siyuan

Coal Geology & Exploration

The seismic resolution has long been limited to the quarter wavelength. To compress the seismic wavelet, the key problems are signal-to-noise ratio (SNR) and resolution in early stages, and high resolution and high fidelity in late stages. Meanwhile, by using well data, many inversion methods of spanning quarter wavelength have been developed. The success of these methods depends on the preservation of seismic wave amplitude, the accuracy of seismic interpretation, and the compatibility between well data and seismic data. Afterward, researchers achieved seismic inversion without well data constraint, and the corresponding resolution reached the level of reflectivity. Meanwhile, the key …

From 1d To 4d: Advances And Thoughts On Coal Seismic Technology, Cheng Jianyuan, Zhang Xianxu, Jiang Bici, Wang Pan, Shan Rui

Coal Geology & Exploration

As one of the key technologies for safe and efficient support of coalmine geology, the seismic technology, has gone through one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D), and progressed from resource exploration to mining area exploration, and from structural exploration to lithological exploration. The latest 4D seismic will further leapfrog from static detection to dynamic detection. Based on the concepts of time-space dimensions and the four seismic development stages, we propose three transitional stages from 1.5D (e.g., non-zero offset VSP), 2.5D (e.g., wide line 2D seismic exploration) to 3.5D (e.g., 3D seismic dynamic interpretation), and also present the time-space characteristics …

Coal Geology & Exploration

The shallow coal resources in North China have been nearly depleted so far, whereas deep coal development is challenged by karst water inrush in floor limestone. The conventional underground vertical hole grouting methods are troubled with inappropriate site location, thin drilling-met aquifer, large grouting blind area, and inaccurate target location. For this reason, we propose an advance regional control technology: bedding directional drilling-based grouting. We systematically study the slurry flow from near-horizontal grouting holes, advance grouting modes, grouting parameter control, advance identification of potential water diversion channels, as well as validation and assessment of a grouting treatment. On this basis, …
