A Steerable , Un te the
We present a steerable, electrostatic, untethered, MEMS micro-robot, with dimensions of 60 /j.m by 250 /j.m by 10 /j.m. This micro-robot is 1 to 2 orders of magnitude smaller in size than previous micro-robotic systems. The device consists of a curved, cantilevered steering arm, mounted on an untethered scratch drive actuator. These two components are fabricated monolithically from the same she...

By combination of structural and elemental characterizations, the corrosion products are evidenced. We observe the formation of platelets and needles, with a better morphological definition in the case of Mg-containing samples. The needles are associated to La(OH)3 and possess nanometric inner hollow channels. The platelets are made of Ni(OH)2 for pure La2Ni7. When Mg is present, we demonstrate...

Finding relevant information on the Web is often difficult for most of the users. Although Web search applications are improving, they still need to be more intelligent to adapt to the search domain targeted by users, the evolution of this domain and users’ characteristics. In this paper, we present an experimental assessment of the TARGET framework for improving the relevance of the documents ...

The communication infrastructure around us is a rich but fragmented environment made of separated services corresponding to different levels of engagement. The multiscale approach to communication proposes instead to create systems that support a variable degree of engagement and smooth transitions between degrees. This paper reports on the design and evaluation of such a system called Pêle-Mêl...

ion Techniques: model-checking raised interest in techniques to abstract infinite to finite models. Provided that the abstraction has been proven sound, testing may be sufficient for establishing correctness [10, 18]. Systematic Testing: the discussion over test adequacy criteria [27], i. e. criteria solving the question “when did we test enough to meet a given test hypothesis,” led to more sys...
