We present a method for face class modeling in the eigenfaces space using a large-margin classifier like SVM. Another issue addressed is how to select the number of eigenfaces to achieve a good classification rate. As the experimental evidence show, genera ...
Ferritic/martensitic steels considered as first-wall candidate materials for fusion reactors experience significant radiation hardening at temperatures below similar to400 degreesC. Experimental evidence suggests that the observed defects are large interst ...
During the last 20 years, backscattered electron imaging of polished surfaces has become well established as a method for the study of cement and concrete microstructures. The technique has many advantages, including the visualisation of representative cro ...
The isotropic magnetic moment of a free atom is shown to develop giant magnetic anisotropy energy due to symmetry reduction at an atomically ordered surface. Single cobalt atoms deposited onto platinum ( 111) are found to have a magnetic anisotropy energy ...
In this work, we consider the multiple antenna systems in which a large number of antennas occupy a given physical volume, and investigate the behavior of the capacity when increasing the number of antennas. In this regime the assumptions of the standard m ...
A transmission electron microscopy of pyramidal inversion domains induced by Mg doping in MOVPE and bulk GaN is presented. Based on high resolution observations and EDX analysis, two atomic models are proposed for the Mg-rich (0001) inversion domain bounda ...
We consider the problem of routing in a wide area mobile ad-hoc network called Terminode Network. Routing in this network is designed with the following objectives. First, it should scale well in terms of the number of nodes and geographical coverage ...
Recently, we introduced two illusions: Feature inheritance and shine-through (Herzog & Koch, 2001). In both cases, a vernier precedes a grating for a short time. In feature inheritance the grating comprises a small number of elements to which properties of ...
Rotationally resolved spectra in the 5 nu (1) region of (CH3OH)-C-13 reveal strong vibrational splittings, which by analogy to (CH3OH)-C-12, we assign to a resonance between 5 nu (1) and 4 nu (1)+nu (2). Accordingly, the vibrational dynamics on a subpicose ...
Choosing the best out of an increasing number of options requires reliable and accurate information. As our time and resources are limited, we commonly use the experience of others in order to take decisions. Reputation mechanisms aggregate in a formal way ...
