A systematic approach to the static analysis of deformation of linear objects such as cords and ropes is presented. There exists many manipulative operations that deal with deformable objects in environments that robots are expected to take active parts, while rigid object manipulation has been a main interest in most of the task planning researches. Manipulative operations that deal with defor...

In cardiovascular tissue engineering, mechanical stimulation of tissue-engineered constructs is known to improve tissue properties. During tissue culture, the mechanical properties of the tissue construct change. To impose a predefined deformation protocol and to avoid negative effects of excessive strain, it is desired to monitor and control deformations during load application. In a previous ...

We present a set of problem frames specialized to the area of geographic applications. Problem frames describe the elements of common problems, and help a specifier understand and decompose a complex problem into simpler subproblems for which a solution is often known. We provide an overview of the main issues in geographic applications, and present twelve frames that address many of the proble...

The present article argues for what is essentially a return to the functionalist approach to investigation of memory. Two experiments demonstrate that the effects of level of processing depend on scaled meaningfulness of the material and study time. Data from those experiments along with data currently in the literature are then reanalyzed to examine the effect of repetitions. Of particular int...

In this paper, we present an original approach for an unsupervised learning of the structure and deformation modes of 2D moving objects in long image sequences. The object representation relies on a statistical description of the deformations applied to a prototype shape. The optimal bayesian estimate of the deformation process is obtained by maximizing a non-linear joint probability distributi...

The ability to plan their own motions and to reliably execute them is an important precondition for autonomous robots. In this paper, we consider the problem of planning the motion of a mobile manipulation robot in the presence of deformable objects in the environment. Our approach combines probabilistic roadmap planning with a deformation simulation system. Since the physical deformation simul...

In this paper, we describe feature-based nonrigid registration of histological serial section images. Our method represents non-rigid deformation by blending the rigid transformations estimated in the local region around a control point. This approach can efficiently represent nonrigid deformation with a smaller number of control points than conventional methods that interpolate displacement, s...

Human musculature is an important structure for appearance and deformation of body surface. In this paper, we propose a new method of muscle modeling based on both anatomical and real-time consideration. Furthermore, we introduce our muscle modeling system. In the system muscle can be constructed and edited easily through appointing some radial and transverse cross-section control parameters. D...
