ARCHITECTURAL HYPER-MODEL: CHANGING ARCHITECTURAL CONSTRUCTION DOCUMENTATION

More architects and spatial designers are producing complex 3D computer models as part of their everyday design process and documentation than ever before. Parallel to this shift, there has been a rapid rise in consumer computer processing power that has made hyper realistic digital environments a part of our home entertainment. Together, the 3D CAD models and the Computer Gaming Engine could become an architectural hyper-model that renders a digital environment in real time. Such a model would enable users to navigate freely, effectively establishing a new mode of reading space that hovers between 2D drawings and a real space.(Nitsche & Roudavski). This paper will examine how these worlds can merge to form an architectural hyper-model as a valuable supplement to the more conventional scaled 2D construction drawing documentation found on construction sites. While easily misconstrued as speculative, the ideas presented in this paper outline an on-going body of innovative research currently at the prototype stage. These prototypical hyper-models explore the possibilities of providing construction workers and project mangers access to an architect’s 3D computer models on site. These models originate from within conventional building construction drawings such as detailed sections and exploded axonometrics. A process of reinterpretation occurs to locate these drawings and their information within an interactive 3D space. Such operations take advantage of the best of both paradigms. This gives users access to, and control of, the 3D information required for communicating necessary information about the building process. It also provides nodes or hyper-links in the 3D representation that connect to additional information, such as specifications, that are perhaps less formal/spatial. The paper will show how architectural hyper-models can be used on the construction site - both in the site office and on site using laptop computers and more compact hand-held devices - to decrease on site confusion and enable a faster and more complete understanding of the architect’s vision. The paper concludes with speculation on the types of additional information construction workers, architects and designers might want to access in the future and proposes additional technologies that could be provided

Improving the Efficiency of Quantum Circuits for Information Set Decoding

The NIST Post-Quantum standardization initiative, that entered its fourth round, aims to select asymmetric cryptosystems secure against attacker equipped with a quantum computer. Code-based cryptosystems are a promising option for Post-Quantum Cryptography (PQC), as neither classical nor quantum algorithms provide polynomial time solvers for its underlying hard problems. Indeed, to provide sound alternatives to lattice-based cryptosystems, NIST advanced all round 3 code-based cryptosystems to round 4. We present a complete implementation of a quantum circuit based on the Information Set Decoding (ISD) strategy, the best known one against code-based cryptosystems, providing quantitative measures for the security margin achieved with respect to the quantum-accelerated key recovery on AES, targeting both the current state-of-the-art approach and the NIST estimates. Our work improves the state-of-the-art, reducing the circuit depth from 2¹⁹ to 2³⁰ for all the parameters of the NIST selected cryptosystems. We further analyse recently proposed optimizations, showing that the overhead introduced by their implementation overcomes their asymptotic advantages. Finally, we address the concern brought forward in the latest NIST report on the parameters choice for the McEliece cryptosystem, showing that the parameter choice yields a computational effort which is slightly below the required target level

Status of Salerno Laboratory (Measurements in Nuclear Emulsion)

A report on the analysis work in the Salerno Emulsion Laboratory is presented. It is related to the search for nu_mu->nu_tau oscillations in CHORUS experiment, the calibrations in the WANF (West Area Neutrino Facility) at Cern and tests and preparation for new experiments.Comment: Proc.
