Wind-tunnel experiments were performed to study turbulence in the wake of a model wind turbine placed in a boundary layer developed over rough and smooth surfaces. Hot-wire anemometry was used to characterize the cross-sectional distribution of mean veloci ...
We investigate the interplay of Dzyaloshinskii-Moriya interactions and an external field in spin-1∕2 dimers. For isolated dimers and at low field, we derive simple expressions for the staggered and uniform magnetizations which show that the orientation of ...
Purpose – Intelligent control for unidentified systems with unstable equilibriums is not always a proper control strategy, which results in inferior performance in many cases. Because of the existing trial and error manner of the procedure in former durati ...
This work presents a numerical model able to simulate the effect of biomass growth on the hydraulic properties of saturated porous media, i.e., bioclogging. A new module for an existing coupled flow and reactive-transport code -- PHWAT -- was implemented. ...
A new traffic-responsive ramp-metering strategy is presented that coordinates local ramp-metering actions, thus enabling the linked control of the inflow from two (or more) consecutive on-ramps to the freeway mainstream. The proposed linked ramp-metering s ...

Optic-flow is believed to be the main source of information allowing insects to control their flight. Some researchers have tried to apply this paradigm to small unmanned aerial vehicles (UAVs). So far, none of them has been able to demonstrate a fully aut ...
We present the three-dimensional (3D) growth of polypyrrole (PPy) microstructures with high aspect ratios (HAR) by a localized electropolymerization. The radicals formed by an oxidation of Py monomer is localized on the targeting area due to a confinement ...
Hydrophilic/hydrophobic patterning is a well-established design strategy to guide secondary structure formation of both natural as well as non-natural oligomers and polymers. This contribution explores the feasibility of a new approach for the synthesis of ...
The paper presents the analysis of black-startup and islanding capabilities of an 80 MW combined cycle power plant. The analysis is carried out by means of a computer dynamic simulator suitably developed in the EMTP-RV simulation environment in order to re ...
The fluorescent imidazolium salt (1,3-bis(9-anthracenylmethyl)imidazolium chloride, [bamim]Cl) has been grafted onto the surfaces of single-walled carbon nanotubes (SWNTs) using an ion exchange strategy based on metathesis of the K+ ion in CO2K derivatized ...
