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...

In the landmark large deformation diffeomorphic metric mapping (landmark-LDDMM) formulation for image registration, we consider the motion of particles which locally translate image data. We then lift the motion of the particles to obtain a motion on the entire image. However, it is certainly possible to consider particles which also apply local rotations, scalings, and sheerings. These locally...

The paper adapts the large deformation diffeomorphic metric mapping framework for image registration to the indirect setting where a template is registered against a target that is given through indirect noisy observations. The registration uses diffeomorphisms that transform the template through a (group) action. These diffeomorphisms are generated by solving a flow equation that is defined by...

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...

The influence of deformation on aerodynamic characteristics is studied in this paper. To study the influences of deformation magnitude and range separately, a kind of twopart flapping wing model is designed, which separates the deformation magnitude and range, and makes the measurement of deformation easier. A series of wind-tunnel experiments are carried out to explore the influence. The exper...

The Shah-Kuh granitoid has intruded in the Triassic–Jurassic, pelitic and psammitic low-grade metamorphic rocks of the NE LutBlock, in Central Iran. Cordierite porphyroblasts are common in the southern pelitic sediments, but are rare in the northern psammiticrocks, in the contact aureole. Deformation fabrics in the contact aureole are well-preserved within the cordierite porphyroblasts. Therela...

Presents article is deal with optimization of the fixture for end milling process, the most important objective being the minimization of work piece deformation by changing the layout of fixture elements and the clamping forces. The main objective of this work has been the optimization of the fixtures Work piece deformation subjected to clamping forces for End milling operation. The present ana...
