  • Robust Classification Method for Underwater Targets Using the Chaotic Features of the Flow Field
    Journal of Marine Science and Engineering Article Robust Classification Method for Underwater Targets Using the Chaotic Features of the Flow Field Xinghua Lin 1, Jianguo Wu 1,* and Qing Qin 2 1 School of Mechanical Engineering, Hebei University of Technology, Tianjin 300401, China; [email protected] 2 China Automotive Technology and Research Center Co., Ltd, Tianjin 300300, China; [email protected] * Correspondence: [email protected] Received: 17 January 2020; Accepted: 10 February 2020; Published: 12 February 2020 Abstract: Fish can sense their surrounding environment by their lateral line system (LLS). In order to understand the extent to which information can be derived via LLS and to improve the adaptive ability of autonomous underwater vehicles (AUVs), a novel strategy is presented, which directly uses the information of the flow field to distinguish the object obstacle. The flow fields around different targets are obtained by the numerical method, and the pressure signal on the virtual lateral line is studied based on the chaos theory and fast Fourier transform (FFT). The compounded parametric features, including the chaotic features (CF) and the power spectrum density (PSD), which is named CF-PSD, are used to recognize the kinds of obstacles. During the research of CF, the largest Lyapunov exponent (LLE), saturated correlation dimension (SCD), and Kolmogorov entropy (KE) are taken into account, and PSD features include the number, amplitude, and position of wave crests. A two-step support vector machine (SVM) is built and used to classify the shapes and incidence angles based on the CF-PSD. It is demonstrated that the flow fields around triangular and square targets are chaotic systems, and the new findings indicate that the object obstacle can be recognized directly based on the information of the flow field, and the consideration of a parametric feature extraction method (CF-PSD) results in considerably higher classification success.

  • Engineering the Quantum Foam
    Engineering the Quantum Foam Reginald T. Cahill School of Chemistry, Physics and Earth Sciences, Flinders University, GPO Box 2100, Adelaide 5001, Australia [email protected] _____________________________________________________ ABSTRACT In 1990 Alcubierre, within the General Relativity model for space-time, proposed a scenario for ‘warp drive’ faster than light travel, in which objects would achieve such speeds by actually being stationary within a bubble of space which itself was moving through space, the idea being that the speed of the bubble was not itself limited by the speed of light. However that scenario required exotic matter to stabilise the boundary of the bubble. Here that proposal is re-examined within the context of the new modelling of space in which space is a quantum system, viz a quantum foam, with on-going classicalisation. This model has lead to the resolution of a number of longstanding problems, including a dynamical explanation for the so-called `dark matter’ effect. It has also given the first evidence of quantum gravity effects, as experimental data has shown that a new dimensionless constant characterising the self-interaction of space is the fine structure constant. The studies here begin the task of examining to what extent the new spatial self-interaction dynamics can play a role in stabilising the boundary without exotic matter, and whether the boundary stabilisation dynamics can be engineered; this would amount to quantum gravity engineering. 1 Introduction The modelling of space within physics has been an enormously challenging task dating back in the modern era to Galileo, mainly because it has proven very difficult, both conceptually and experimentally, to get a ‘handle’ on the phenomenon of space.

  • Hyperbolic Prism, Poincaré Disc, and Foams
    Hyperbolic Prism, Poincaré Disc, and Foams 1 1 Alberto Tufaile , Adriana Pedrosa Biscaia Tufaile 1 Soft Matter Laboratory, Escola de Artes, Ciências e Humanidades, Universidade de São Paulo, São Paulo, Brazil (E-mail: [email protected]) Abstract. The hyperbolic prism is a transparent optical element with spherical polished surfaces that refracts and reflects the light, acting as an optical element of foam. Using the hyperbolic prism we can face the question: is there any self-similarity in foams due to light scattering? In order to answer this question, we have constructed two optical elements: the hyperbolic kaleidoscope and the hyperbolic prism. The key feature of the light scattering in such elements is that this phenomenon is chaotic. The propagation of light in foams creates patterns which are generated due to the reflection and refraction of light. One of these patterns is observed by the formation of multiple mirror images inside liquid bridges in a layer of bubbles in a Hele-Shaw cell. We have observed the existence of these patterns in foams and their relation with hyperbolic geometry using the Poincaré disc model. The images obtained from the experiment in foams are compared to the case of hyperbolic optical elements, and there is a fractal dimension associated with the light scattering which creates self-similar patterns Keywords: Hyperbolic Prism, Poincaré Disc, Foams, Kaleidoscope. 1 Introduction Physically based visualization of foams improves our knowledge of optical systems. As long as the light transport mechanisms for light scattering in foams are understood, some interesting patterns observed can be connected with some concepts involving hyperbolic geometry, and this study involves mainly the classical scattering of light in foams and geometrical optics.

  • Modelling and Simulation of Acoustic Absorption of Open Cell Metal Foams
    Modelling and Simulation of Acoustic Absorption of Open Cell Metal Foams Claudia Lautensack, Matthias Kabel Fraunhofer ITWM, Kaiserslautern Abstract We analyse the microstructure of an open nickel-chrome foam using computed tomography. The foam sample is modelled by a random Laguerre tessellation, i.e. a weighted Voronoi tessellation, which is fitted to the original structure by means of geometric characteristics estimated from the CT image. Using the Allard-Johnson model we simulate the acoustic absorption of the real foam and the model. Finally, simulations in models with a larger variation of the cell sizes yield first results for the dependence of acoustic properties on the geometric structure of open cell foams. 1. Introduction Open cell metal foams are versatile materials which are used in many application areas, e.g. as heat exchangers, catalysts or sound absorbers. The physical properties of a foam are highly affected by its microstructure, for instance the porosity or the specific surface area of the material or the size and shape of the foam cells. An understanding of the change of the foam’s properties with altering microstructure is crucial for the optimisation of foams for certain applications. Foam models from stochastic geometry are powerful tools for the investigation of these relations. Edge systems of random tessellations are often used as models for open foams. Geometric characteristics which are estimated from tomographic images of the foams are used for fitting the models to real data. Realisations of foams with slightly modified microstructure can then be generated by changing the model parameters. Numerical simulations in these virtual foam samples allow for an investigation of relations between the geometric structure of a material and its physical properties.

  • Low Rattling: a Predictive Principle for Self-Organization in Active Collectives

General principles describing self-organization away from equilibrium have been challenging to iden- tify. We offer a unifying framework that models the behavior of com- plex systems as largely random, while capturing their configuration- dependent response to external forcing. This allows derivation of a Boltzmann-like principle for understanding and manipulating driven self-organization. We validate our predictions experimentally in shape- changing robotic active matter, and outline a methodology for con- trolling collective behavior. Our findings highlight how emergent or- arXiv:2101.00683v1 [cond-mat.stat-mech] 3 Jan 2021 der depends sensitively on the matching between external patterns of forcing and internal dynamical response properties, pointing towards future approaches for design and control of active particle mixtures and metamaterials. 1 ACCEPTED VERSION: This is the author's version of the work.

  • Fibonacci Numbers and the Golden Ratio in Biology, Physics, Astrophysics, Chemistry and Technology: a Non-Exhaustive Review
    Fibonacci Numbers and the Golden Ratio in Biology, Physics, Astrophysics, Chemistry and Technology: A Non-Exhaustive Review Vladimir Pletser Technology and Engineering Center for Space Utilization, Chinese Academy of Sciences, Beijing, China; [email protected] Abstract Fibonacci numbers and the golden ratio can be found in nearly all domains of Science, appearing when self-organization processes are at play and/or expressing minimum energy configurations. Several non-exhaustive examples are given in biology (natural and artificial phyllotaxis, genetic code and DNA), physics (hydrogen bonds, chaos, superconductivity), astrophysics (pulsating stars, black holes), chemistry (quasicrystals, protein AB models), and technology (tribology, resistors, quantum computing, quantum phase transitions, photonics). Keywords Fibonacci numbers; Golden ratio; Phyllotaxis; DNA; Hydrogen bonds; Chaos; Superconductivity; Pulsating stars; Black holes; Quasicrystals; Protein AB models; Tribology; Resistors; Quantum computing; Quantum phase transitions; Photonics 1. Introduction Fibonacci numbers with 1 and 1 and the golden ratio φlim → √ 1.618 … can be found in nearly all domains of Science appearing when self-organization processes are at play and/or expressing minimum energy configurations. Several, but by far non- exhaustive, examples are given in biology, physics, astrophysics, chemistry and technology. 2. Biology 2.1 Natural and artificial phyllotaxis Several authors (see e.g. Onderdonk, 1970; Mitchison, 1977, and references therein) described the phyllotaxis arrangement of leaves on plant stems in such a way that the overall vertical configuration of leaves is optimized to receive rain water, sunshine and air, according to a golden angle function of Fibonacci numbers. However, this view is not uniformly accepted (see Coxeter, 1961). N. Rivier and his collaborators (2016) modelized natural phyllotaxis by the tiling by Voronoi cells of spiral lattices formed by points placed regularly on a generative spiral.
