We introduce a constraint-based motion editing technique enforcing the intrinsic motion flow of a given motion pattern (e.g., golf swing). Its major characteristic is to operate in the motion Principal Coefficients (PCs) space instead of the pose PCs space ...
The rapid evolution in microsystems and optoelectronics creates the demand for robotic production means with increased performance. The required precision for specific tasks in machining, positioning and assembly is a factor 10 to 100 better than 1 microme ...
The Hita-STT is a five-axis parallel kinematics machine-tool designed for machining and polishing complex parts for applications in medical, automotive components, watch industries. The kinematics of Hita-STT prototype presents an over-constrained design i ...
A multifunctional hybrid glass fiber-reinforced polymer (GFRP)/steel joint has been developed for the transfer of compression and shear forces in thermal insulation sections of concrete slab structures used in building construction. The new pultruded cellu ...
In addition to glue-laminated timber, screw-laminated timber has increasingly been applied to rib shells. The ribs are made from laminated timber boards, which are joined together with the aid of pin-like fasteners such as screws or nails. The current rese ...
In this paper, we present a new method for solving the Motion Retargeting Problem, by using an intermediate skeleton. This allows us to convert movements between hierarchically and geometrically different characters. An Inverse Kinematics engine is then us ...
We present a new method for solving the motion retargeting problem, by using an intermediate skeleton. This allows us to convert movements between hierarchically and geometrically different characters. An inverse kinematics engine is then used to enforce C ...
We investigate the behavior of isotropic invariant subspaces of skew-Hamiltonian matrices under structured perturbations. It is shown that finding a nearby subspace is equivalent to solving a certain quadratic matrix equation. This connection is used to de ...

This thesis deals with the study of G-forms and particulary the trace form of a G-Galois algebra. Let k be a field of characteristic not two. Let G be a finite group and L a G-Galois algebra over k. We define the trace form qL by qL(x, y) = TrL/k(xy) for a ...
We present a new method for estimating heart motion from two-dimensional echocardiographic sequences by exploiting two ultrasound modalities: B-mode and tissue Doppler. The algorithmestimates a two-dimensional velocity field locally by using a spatial affi ...
