Scale-Space Splatting: Reforming Spacetime for the Cross-Scale Exploration of Integral Measures in Molecular Dynamics [PDF]
, 2019 Understanding large amounts of spatiotemporal data from particle-based simulations, such as molecular dynamics, often relies on the computation and analysis of aggregate measures. These, however, by virtue of aggregation, hide structural information about the space/time localization of the studied phenomena.

Visualising higher-dimensional space-time and space-scale objects as projections to ℝ3 [PDF]
PeerJ Computer Science, 2017 Objects of more than three dimensions can be used to model geographic phenomena that occur in space, time and scale. For instance, a single 4D object can be used to represent the changes in a 3D object’s shape across time or all its optimal ...

Scale Space for Camera Invariant Features
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2014 In this paper we propose a new approach to compute the scale space of any central projection system, such as catadioptric, fisheye or conventional cameras. Since these systems can be explained using a unified model, the single parameter that defines each

Simulacra of emptiness. The model as habitable space
Agathón, 2020 This contribution is part of a study dedicated to the architectural model as a tool able to reveal the formal generative process of the project. This text develops the topic of the relationship between space and form, further analysing the relationship ...

Scale-Space Processing Using Polynomial Representations
2014 IEEE Conference on Computer Vision and Pattern Recognition, 2014 In this study, we propose the application of principal components analysis (PCA) to scale-spaces. PCA is a standard method used in computer vision. The translation of an input image into scale-space is a continuous operation, which requires the extension

Anisotropic diffusion processes in early vision [PDF]
, 1989 Summary form only given. Images often contain information at a number of different scales of resolution, so that the definition and generation of a good scale space is a key step in early vision. A scale space in which object boundaries are respected and

Non-Gaussian Scale Space Filtering with 2 by 2 Matrix of Linear Filters [PDF]
arXiv, 2011 Construction of a scale space with a convolution filter has been studied extensively in the past. It has been proven that the only convolution kernel that satisfies the scale space requirements is a Gaussian type. In this paper, we consider a matrix of convolution filters introduced in [1] as a building kernel for a scale space, and shows that we can ...

A Scale-Separated Approach for Studying Coupled Ion and Electron Scale Turbulence [PDF]
, 2019 Multiple space and time scales arise in plasma turbulence in magnetic confinement fusion devices because of the smallness of the square root of the electron-to-ion mass ratio $(m_e/m_i)^{1/2}$ and the consequent disparity of the ion and electron thermal gyroradii and thermal speeds.

Manufacturing process of water-soluble salt-based ceramic cores based on vat photopolymerization
Journal of Advanced CeramicsWater-soluble salt-based ceramic cores can be recycled and have excellent high-temperature chemical stability. In this work, vat photopolymerization was successfully applied to water-soluble salt-based ceramic cores for the first time.

Evolution of Bulk Scale Factor in Warped Space-time [PDF]
, 2012 In this work the role of extra dimensions in the accelerated universe through the scenario of higher-dimensional Friedmann-Robertson-Walker (FRW) cosmology has been studied. For this purpose, we first consider warped space-time in the standard flat brane
