We address continuous free-form sculpting of 3D models that carry self-similar geometric details. In addition to being maintained when the model is bent or twisted, repetitive details should be duplicated rather than deformed in stretched regions, so that their distribution and appearance are preserved. Doing so in a temporally coherent way is essential in applications where the user sculpts th...

In order to design industrial products fitting well to the human body, it is necessary to make full use of information of human anatomical landmarks. These landmarks however cannot be extracted automatically from point cloud data of human body surface obtained by a 3D scanner. In our previous report, we proposed the method of extracting the landmarks automatically by deforming the template of p...

Frontier-based exploration is the most common approach to exploration, a fundamental problem in robotics. In frontier-based exploration, robots explore by repeatedly computing (and moving towards) frontiers, the segments which separate the known regions from those unknown. However, most frontier detection algorithms process the entire map data. This can be a time consuming process which slows d...

Kurzfassung. In der vorliegenden Arbeit wird ein neuartiger Ansatz zur Approximation des Masseeffekts von primären Hirntumoren beschrieben. Die Progression des Tumors wird mittels einer deterministischen Reaktionsdiffusionsgleichung modelliert. Die Beschreibung der raumfordernden Wirkung des Tumors erfolgt über die Kopplung der resultierenden Verteilung der Tumorzellkonzentration mit einem para...

this paper presents theoretical and numerical state-of-the-art information in the field of hygro-thermo-mechanical deformation simulation in structural concrete. the aspects discussed include coupled hygro-thermo-mechanical performance of porous materials including concrete, multi-scale simulation of concrete properties especially the volumetric and structural deformation performance, and the m...

The potassium form of d(CGCGAATTCGCG) solved by X-ray diffraction to 1.75 A resolution indicates that monovalent cations penetrate the primary and secondary layers of the "spine of hydration". Both the sodium [Shui, X., McFail-Isom, L., Hu, G. G., and Williams, L. D. (1998) Biochemistry 37, 8341-8355] and the potassium forms of the dodecamer at high resolution indicate that the original descrip...

Complex light-matter interactions in azobenzene polymers have limited our understanding of how photoisomerization induces deformation as a function of the underlying polymer network and form of the light excitation. A unified modeling framework is formulated to advance the understanding of surface deformation and bulk deformation of polymer films that are controlled by linear or circularly pola...

Haiqing Xianyu Kuan-Ming Chen Shin-Tson Wu Abstract — An electrically controllable blueshift of the reflection band is observed in a cholesteric liquid crystal with either positive or negative dielectric anisotropy. The change in optical properties is a result of a two-dimensional periodic undulation of the cholesteric texture, known as Helfrich deformation. This blueshift mechanism was used to...

Caricatures are a form of humorous visual art, usually created by skilled artists for the intention of amusement and entertainment. In this paper, we present a novel approach for automatic generation of a computer caricature from a facial photograph, which captures artistic deformation styles from hand-drawn caricatures. In order to achieve this, we propose a pseudo stress-strain model to encod...

Associate to a rewrite system R having rules l → r, its labelled version R having rules l ◦ m+1 → r • m , for any natural number m ∈ ω. These rules roughly express that a left-hand side l carrying labels all larger than m can be replaced by its right-hand side r carrying labels all smaller than or equal to m. A rewrite system R enjoys finite family developments (FFD) if R is terminating. We sho...
