Floating Car Data (FCD) is becoming a more and more popular technique for travel time measurements in road networks. Nevertheless, FCD is a sampling technique which requires controlling the statistical properties of link travel times to obtain accurate est ...
This device for measuring Brillouin scattering includes a single laser source (11), a modulator (12) placed on the path of the light emitted by the source (11) and designed to generate a pumping signal and a test signal which are injected to one end (13) o ...
Energy consumption is a major issue for inertial drives with piezoelectric actuators that are integrated in autonomous devices. This paper discusses some theoretical aspects and some experimental results about the energy consumption of inertial drives with ...
The temporal evolution of the sawtooth crash in ASDEX Upgrade Ohmic and ECRH heated discharges is analysed using a heuristic reconnection model to simulate measured ECE signals. The method turns out to be well suited to detect islands of width above 0.1-0. ...
In this Thesis we study several aspects of potential scattering in non-relativistic quantum mechanics. In the first part, we study the concept of time delay. More precisely, after an elementary introduction to the theory (chapter I), we clarify in chapter ...
In the free-radical polymn. of styrene, a pulsed- or batch-type of polymn. process gave a higher space-time yield and efficiency than a stationary process at the same product mol. wt. and polydispersity. In the batch process, the range of av. mol. wt., con ...
We present a measurement of CP-violation parameters in the b→sq̄q penguin transitions (q = s,u,d) based on a 78 fb-1 data sample collected at the Y(4S) resonance with the Belle detector at the KEKB energyasymmetric e+e- collider. One neutral B meson is rec ...
We present a new method for estimating heart motion from two-dimensional (2D) echocardiographic sequences. It is inspired by the Lucas-Kanade algorithm for optical flow which estimates motion parameters over a sliding window. However, instead of assuming t ...
High-purity HSO3Cl is prepd. at a high space-time yield by mixing and reacting gaseous HCl with SO3 dissolved in ClSO3H, contg. 0.3-1.4% SO3 at 70-100 Deg in a venturi tube at 1-1.1 mol HCl/mol SO3. Thus, into the throat of a vertical venturi tube was fed ...
The title polymers of dialkenyldialkylammonium compds., useful in the coating and prepn. of paper, are prepd. in high space-time yield by the continuous or batch addn. of H2O-insol. azo compd. initiators in MeOH or DMF to aq. monomers. Thus, adding ten 2-m ...
