Theoretical investigations and numerical and laboratory experiments were conducted to evaluate the feasibility and limitations of describing solute transport and water flow in regularly structured porous media with an equivalent homogeneous continuum appro ...
Voids are often present in composite materials and have, as may be expected, negative effects on the mechanical properties. As a consequence, it is regarded to be important to optimise manufacturing techniques of composite materials towards minimum void co ...
This paper presents an investigation of the hydro elastic behavior of vibrating blades in hydraulic machines, which is of strong interest for turbo machinery applications. As a representative case study for vibrating blade in hydraulic machines, a NACA 000 ...
Using Monte Carlo simulations for a semi-infinite medium representing a skeletal muscle tissue, it is demonstrated that the zero- and first-order moments of the power spectrum for a representative pixel of a full-field laser-Doppler imager behave different ...
Selective Ga + ion implantation and miring by focused ion beam exposure and subsequent wet chemical etching is used to fabricate micro/nanomechanical elements in Si. Freestanding elements with a ~ 30 nm membrane thickness are made by controlled selective u ...
This paper describes a new model for the structural behavior of composite beam-columns with partial interaction. This second-order model doesn't make use of the centroid of the transformed cross-section area of the fully composite member, but the centroids ...
This paper presents the results of a method to produce autonomous animation of virtual humans. In particular, the proposed methodology is focused on the autonomous synthesis of nonvoluntary gestures such as reflexes and subtle movements which provide a not ...
The paper presents results from an experimental and analytical study of interior columns subjected to punching in the presence of an unbalanced moment. The moment, characterized in the study by an eccentricity of the load in the column, is shown to have a ...
We present a formalism based on the method of moment to solve the volume integral equation using tetrahedral (3-D) and triangular (2-D) elements. We introduce a regularization scheme to handle the strong singularity of the Green's tensor. This regularizati ...

The feasibility of a new, 2-laser, isotope sepn. scheme was tested. The 1st laser induces isotopically selective condensation in the collisional region of a free jet of SF6 dild. in Ar. Thus, a mol. beam contg. non-clustered 32SF6 and clustered 34SF6{m}Ar{ ...
