We present an automatic sub-pixel registration algorithm that minimizes the mean square difference of intensities between a reference and a test data set, which can be either tri-dimensional (3-D) volumes or bi-dimensional (2-D) images. It uses spline proc ...
We propose a new type of “hybrid” ultrasonic driving principle for our monolithic piezoelectric actuators, which consist of simple electrode patterning on a PZT ceramic substrate The operating principle of the proposed USM is based on the conversion of ell ...
The ab-plane optical properties of the high-temperature superconductor Bi2Sr2CaCu2O8 are anisotropic in both the normal and the superconducting state. Consistent with the orthorhombic structure, the principal axes lie along the a and b crystallographic axe ...
Relative state-to-state cross sections for inelastic collisions between NO X (2) Pi(1/2) (upsilon = 20, J = 0.5, e or f) and He have been determined in a crossed molecular beam setup at a collision energy of 195 cm(-1). Efficient initial state preparation ...
In this paper we show how the mass properties of an articulated body, such as its center of mass and its moments of inertia, may be manipulated like any conventional end effector, with well-known iterative, numerical techniques. Within our interactive simu ...

We propose a method to simulate human bodies based on anatomy concepts. We believe that the closer our model is to reality, the better our results will be. Using this approach, we are developing our human representation. Our model is divided into three lay ...
In this work, statistical based motion estimation is applied to the problem of motion estimation for video coding. We show that the motion equations of a rigid body can be formulated as a nonlinear dynamic system whose state is represented by the motion pa ...
Three-dimensional (3-D) motion estimation is applied to the problem of motion compensation for video coding. We suppose that the video sequence consists of the perspective projections of a collection of rigid bodies which undergo a rototranslational motion ...
We investigated the integration of neck muscle afferents during walking and running. Subjects walked or ran straight ahead, with or without an additional mass (20% of body weight). They performed all trials without vibration and with continuous vibration ( ...
The invention concerns a vehicle whereof the rigid body (1, 2, 4) comprises the front element (20) forming the rear element of a deformable articulated quadrilateral (17, 18, 19, 20). The element (17) is mounted in the extension of the arm (15) linked to t ...
