The aim of this work was to analyze the global behavior of a loudspeaker exciting a room in the frequency band of its first modes, for the purpose of active control applications. First, the loudspeaker in free field was studied. The characterization of a l ...
An 8 times 16 array of sensing micro-sites employs a fully-electrical label-free technique for DNA recognition using capacitance measurement and is fabricated in 0.5mum CMOS with added noble metal. Repeatability and parallel detection capability have been ...
The arterial system can be modelled by means of distributed analogs and by lumped parameter representations, such as the Windkessel. The distributed models, together with biological data, lead to the explanation of arterial function in terms of pressure an ...
Suitably shaped metal nanostructures act as resonant optical antennas that efficiently collect light and confine it to a subwavelength volume. Vice versa, light emission from nano volumes can be enhanced by coupling to antenna structures. We give a short i ...
Within the framework of an outdoor active noise control project, a need arose, namely to establish whether electrodynamic loudspeakers are likely to be affected by the primary noise or by the interactions between them. The aim of this thesis is therefore t ...
A review with 80 refs. Permanent modification is an important recent development in chem. modification techniques which is promising in view of increasing sample throughput with 'fast' programs, reducing reagent blanks, preliminary elimination of unwanted ...
We present an integrated composite right/left handed transmission line (CRLH-TL) phase shifter analogically controlled by means of a MEMS series capacitor. The device is based on coplanar waveguide (CPW) technology and operates at a central frequency of 18 ...
A new, compact way to match slot antennas to a coplanar waveguide (CPW) feed is presented. In addition to its advantages of flexibility, reduced size, and increased bandwidth, a good analytical approximation of the matched antenna behavior is possible. An ...
We generalize density-functional perturbation theory for lattice dynamics to Vanderbilt's ultrasoft pseudopotential scheme. This formulation accounts for the nonorthogonality of the orbitals, the augmentation of the electron density, and the dependence of ...
A method to extract a lumped-parameter equivalent circuit for a free-free flexural MEMS resonator, based on the Euler-Bernoulli beam equation and exploiting a modal analysis approach, is presented. The dynamic behaviour predicted by the equivalent circuit ...
