    Proceedings of the 10th International congress on architectural technology (ICAT 2024): architectural technology transformation.

    Get PDF
    The profession of architectural technology is influential in the transformation of the built environment regionally, nationally, and internationally. The congress provides a platform for industry, educators, researchers, and the next generation of built environment students and professionals to showcase where their influence is transforming the built environment through novel ideas, businesses, leadership, innovation, digital transformation, research and development, and sustainable forward-thinking technological and construction assembly design

    Machine learning in solar physics

    The application of machine learning in solar physics has the potential to greatly enhance our understanding of the complex processes that take place in the atmosphere of the Sun. By using techniques such as deep learning, we are now in the position to analyze large amounts of data from solar observations and identify patterns and trends that may not have been apparent using traditional methods. This can help us improve our understanding of explosive events like solar flares, which can have a strong effect on the Earth environment. Predicting hazardous events on Earth becomes crucial for our technological society. Machine learning can also improve our understanding of the inner workings of the sun itself by allowing us to go deeper into the data and to propose more complex models to explain them. Additionally, the use of machine learning can help to automate the analysis of solar data, reducing the need for manual labor and increasing the efficiency of research in this field.Comment: 100 pages, 13 figures, 286 references, accepted for publication as a Living Review in Solar Physics (LRSP

    Binary Radiance Fields

    Full text link
    In this paper, we propose binary radiance fields (BiRF), a storage-efficient radiance field representation employing binary feature encoding that encodes local features using binary encoding parameters in a format of either +1+1 or −1-1. This binarization strategy lets us represent the feature grid with highly compact feature encoding and a dramatic reduction in storage size. Furthermore, our 2D-3D hybrid feature grid design enhances the compactness of feature encoding as the 3D grid includes main components while 2D grids capture details. In our experiments, binary radiance field representation successfully outperforms the reconstruction performance of state-of-the-art (SOTA) efficient radiance field models with lower storage allocation. In particular, our model achieves impressive results in static scene reconstruction, with a PSNR of 31.53 dB for Synthetic-NeRF scenes, 34.26 dB for Synthetic-NSVF scenes, 28.02 dB for Tanks and Temples scenes while only utilizing 0.7 MB, 0.8 MB, and 0.8 MB of storage space, respectively. We hope the proposed binary radiance field representation will make radiance fields more accessible without a storage bottleneck.Comment: 21 pages, 12 Figures, and 11 Table

    Recent Advances in Research on Island Phenomena

    Get PDF
    In natural languages, filler-gap dependencies can straddle across an unbounded distance. Since the 1960s, the term “island” has been used to describe syntactic structures from which extraction is impossible or impeded. While examples from English are ubiquitous, attested counterexamples in the Mainland Scandinavian languages have continuously been dismissed as illusory and alternative accounts for the underlying structure of such cases have been proposed. However, since such extractions are pervasive in spoken Mainland Scandinavian, these languages may not have been given the attention that they deserve in the syntax literature. In addition, recent research suggests that extraction from certain types of island structures in English might not be as unacceptable as previously assumed either. These findings break new empirical ground, question perceived knowledge, and may indeed have substantial ramifications for syntactic theory. This volume provides an overview of state-of-the-art research on island phenomena primarily in English and the Scandinavian languages, focusing on how languages compare to English, with the aim to shed new light on the nature of island constraints from different theoretical perspectives

    TRANSEUNTIS MUNDI, A NOMADIC ARTISTIC PRACTICE

    Get PDF
    In this practice-led Ph.D. research, I investigate how an artistic practice can respond to the migration phenomena performed by human beings across the planet over millennia ¬– what I refer to as the millennial global human journey. Based on the idea of mobility, I chose to frame this research in the articulation of concepts deriving from the prefix trans: transculture, transhumance and transmediality. This research contributes to studies in art composition by developing the processes and concept of transmedial composition, mainly contributing to the field of New Media Art. This investigation resulted in the work Transeuntis Mundi (TM) Project – a nomadic artistic practice that encompasses: the TM Derive and manual, the TM Archive, the TM VR work Derive 01 and two forms for its notation. Transeuntis mundi (TM), from the Latin language, means the ‘passersby of the world’ and metaphorically personify in this work the millennial migrants and their global journeys. Based on proposals from the Realism art movement and the walking-based methodologies of Walkscapes and DĂ©rive, the TM Derive was created as a nomadic methodology of composition in response to the ideas of migration and ancestry. It is framed by the minimal stories ¬– the form of narrative of this work, captured from field recordings with 3D technology of everyday life worldwide. This material formed the TM Archive, presented in the TM VR work. The TM VR work Transeuntis Mundi Derive 01 is an immersive and interactive performative experience for virtual reality, that artistically brings together stories, sounds, images, people, and places worldwide, ÂŹas a metaphor of the millennial global human migration. This work happens as a VR application using 3D technology with 360Âș image and ambisonic sound, in order to promote an engaged experience through the immersion and interactivity of the participant. This thesis presents and contextualizes these creations: the scope, references, concepts, origin, collaborations, methodology, technologies, and results of this work. It is informed and accompanied by reflexive and critical writing, including an articulation with references of works across different artistic media and fields.UNIRIO Federal University of the State of Rio de Janeir

    Semantic Communications with Variable-Length Coding for Extended Reality

    Full text link
    Wireless extended reality (XR) has attracted wide attentions as a promising technology to improve users' mobility and quality of experience. However, the ultra-high data rate requirement of wireless XR has hindered its development for many years. To overcome this challenge, we develop a semantic communication framework, where semantically-unimportant information is highly-compressed or discarded in semantic coders, significantly improving the transmission efficiency. Besides, considering the fact that some source content may have less amount of semantic information or have higher tolerance to channel noise, we propose a universal variable-length semantic-channel coding method. In particular, we first use a rate allocation network to estimate the best code length for semantic information and then adjust the coding process accordingly. By adopting some proxy functions, the whole framework is trained in an end-to-end manner. Numerical results show that our semantic system significantly outperforms traditional transmission methods and the proposed variable-length coding scheme is superior to the fixed-length coding methods.Comment: 1. Update the performance of VL-SCC in Fig8. under new rate allocation architecture 2. Give a fair comparison between VL-SCC and SCC in Fig9. 3. fix the typo of LDPC rate (1/3 changed to 2/3) 4.
