The effect of drainage front morphology on gaseous diffusion through partially saturated porous media is analyzed using the lattice Boltzmann method (LBM). Flow regimes for immiscible displacement in porous media have been characterized as stable displacem ...
We will explore dynamic perception following the visually guided grasping of several objects by a human-like autonomous robot. This competency serves for object categorization. Physical interaction with the hand-held object gives the neural network of the ...
This paper addresses the question of the coherence in the infrastructures. More precisely, it examines the articulation between technical and institutional coherence. It assumes that a certain degree of such coherence is necessary for infrastructures (netw ...
This thesis studies the implications of using public key cryptographic primitives that are based in, or map to, the multiplicative group of finite fields with small extension degree. A central observation is that the multiplicative group of extension field ...

Several physical quantities of interest are of quantum nature, often measurable as distinct particles. Light is one such example, photons being its particles. In conventional detectors, light is converted onto electrical charges and hence onto a current or ...
Nowadays, virtual humans such as non-player characters in computer games need to have a strong autonomy in order to live their own life in persistent virtual worlds. When designing autonomous virtual humans, the action selection problem needs to be conside ...
We report here infrared spectra of protonated and lithiated valine with varying degrees of hydration in the gas phase and interpret them with the help of DFT calculations at the B3LYP/6-31++G** level. In both the protonated and lithiated species, our resul ...
Understanding how the information is coded in large neuronal networks is one of the major challenges for neuroscience. A possible approach to investigate the information processing capabilities of the neuronal ensembles is given by the use of dissociated n ...
This paper presents a novel locomotion concept for mobile micro robots: the “friction drive principle”. It allows for easy miniaturization and high velocities for low power consumption and simple onboard electronics. A prototype (Ø20 mm × 7.5 mm) with two ...
We introduce "derandomized" versions of the tensor product and the zig-zag product, extending the ideas in the derandomized squaring operation of Rozenman and Vadhan. These enable us to obtain graphs with smaller degrees than those obtained using their non ...
