Design Transformations for Rule-based Procedural Modeling

Mark Pauly, Stefan Lienhard, Cheryl Shaulya Lau

We introduce design transformations for rule-based procedural models, e.g., for buildings and plants. Given two or more procedural designs, each specified by a grammar, a design transformation combines elements of the existing designs to generate new desig ...

Analysis and Synthesis of Structured Variations in 3D Geometries

Ngoc Minh Dang

In recent years, the use of 3D digital content becomes widespread in various industrial and scientific domains. However, content creation still remains a costly task as extensive manual work is often required. As such, one of the core research topics in co ...

Designing modeling notations readers understand

George Popescu

[Context] IT modelers create models to communicate their conceptualization of an organization and to facilitate the collaboration between business and IT people. The story they convey in their models is how the corporate IT systems fulfill the business peo ...

Alkali-silica reaction: Current understanding of the reaction mechanisms and the knowledge gaps

Cyrille Dunant

Alkali-silica reaction (ASR) is a major concrete durability problem, resulting in significant maintenance and reconstruction costs to concrete infrastructures all over the world. Despite decades of study, the underlying chemical and physical reaction mecha ...

Interactive Design of Probability Density Functions for Shape Grammars

Mark Pauly, Duygu Ceylan, Boris Neubert, Stefan Lienhard

A shape grammar defines a procedural shape space containing a variety of models of the same class, e.g. buildings, trees, furniture, airplanes, bikes, etc. We present a framework that enables a user to interactively design a probability density function (p ...

Activities of daily living with reverse prostheses: importance of scapular compensation for functional mobility of the shoulder

Dominique Pioletti, Alexandre Terrier, Alain Farron, Patricia Scheuber

Hypothesis: The nonanatomical design of reverse shoulder prostheses induce medial displacement of the center of rotation, impingements and may reduce the mobility of the shoulder. The aim of this study is to test the hypothesis that during activities of da ...

Statistical Analysis of Ion Mobility Spectrometry. I. Unbiased and Guided Replica-Exchange Molecular Dynamics

Yury Tsybin

Achieving (bio) macromolecular structural assignment from the interpretation of ion mobility spectrometry (IMS) experiments requires successful comparison with computer modeling. Replica-exchange molecular dynamics simulations with suitable force fields no ...

Estimating the time scale and anatomical location of atrial fibrillation spontaneous termination in a biophysical model

Jean-Marc Vesin, Vincent Jacquemet, Laurent Renaud Uldry, Lukas Kappenberger

Due to their transient nature, spontaneous terminations of atrial fibrillation (AF) are difficult to investigate. Apparently, confounding experimental findings about the time scale of this phenomenon have been reported, with values ranging from 1 s to 1 mi ...

Extension of Unified Formulation for the FDTD Simulation of Nonlinear Dispersive Media

Ali Naqavi, Sina Khorasani

A simple approach is extended for the simulation of Kerr-nonlinear and/or dispersive media through the finite-difference time-domain method. The scheme is able to include different types of linear and nonlinear dispersion in a single and unified formulatio ...

Populating Ancient Pompeii with Crowds of Virtual Romans

Daniel Thalmann, Jonathan Maim, Barbara Yersin

Pompeii was a Roman city, destroyed and completely buried during an eruption of the volcano Mount Vesuvius. We have revived its past by creating a 3D model of its previous appearance and populated it with crowds of Virtual Romans. In this paper, we detail ...

Computer Modeling of YBCO Fault Current Limiter Strips Lines in Over-Critical Regime With Temperature Dependent Parameters

Francesco Grilli, Joseph Duron, Bertrand Dutoit, Bertrand Dutoit

We present the results of an advanced numerical model for fault current limiter (FCL) based on HTS thin films in which both thermal and electromagnetic aspects are taken into account. This model allows simulating the behavior of FCL in the over-critical cu ...
