In guided urban automated transportation systems, the maintenance of a high-quality broadband train-to-wayside communication at all locations along the track poses a major problem. Several techniques are currently used. However, to achieve sufficient rates ...

We show that self-ordered anodic aluminum oxide containing hexagonal arrays of cylindrical nanopores with submicron periodicity is a versatile model system for the exploration of rich phononic phenomena at gigahertz frequencies, which are intimately linked ...
The invention relates to an apex-locating method and device for determining the depth position of the apex in a dental root canal. It uses a device that makes it possible to form a circuit comprising a first electrode-probe inserted in the root canal of a ...
In many European cities public transport, particularly busses, are unattractive and underused, due to the lack of direct connections, the need of transfers and the loss of time and comfort. Hence, this study aims at developing the business concept of an al ...
This article is concerned with the existence and orbital stability of standing waves for a nonlinear Schrodinger equation (NLS) with a nonautonomous nonlinearity. It continues and concludes the series of papers [6, 7, 8]. In [6], the authors make use of a ...
The Nine Hole Peg Test (NHPT) is routinely used in clinical environments to evaluate a patient’s fine hand control. A physician measures the total time required to insert nine pegs into nine holes and obtains information on the dexterity of the patient. Ev ...
We report on lattice-matched InAlN/GaN MOSHEMTs with an oxide-filled recess, self-aligned to the gate prepared by thermal oxidation at 800 degrees C in oxygen atmosphere. The device delivered a maximum current density of 2.4 A/mm. Pulse measurements showed ...
This paper analyses the fragmentation of kidney stones by direct impact with Swiss Lithoclast Master(R). Based on a previous work, the impact of the probe of the Lithoclast is modeled with a displacement control of the nodes inside the impacted area. Diffe ...
This thesis aimed at developing new 3D structuration techniques for a relatively recent new ceramic technology called LTCC, which stands for Low Temperature, Co-fired Ceramic. It is a material originally developed for the microelectronic packaging industry ...
Technology scaling and three-dimensional integration are two design paradigms that offer high device density. Process variations affect these design paradigms in different ways. The effect of process variations on clock skew for a 2-D circuit implemented a ...
