Nonlinear model predictive control for the ALSTOM gasifier. [PDF]
In this work a nonlinear model predictive control based on Wiener model has been developed and used to control the ALSTOM gasifier. The 0% load condition was identified as the most difficult case to control among three operating conditions.

A Comprehensive Mixed-Mode Time-Domain Load- and Source-Pull Measurement System [PDF]
We present a novel test set devised for nonlinear balanced device characterization using load-pull techniques. The system is capable of measuring the voltage and current waveforms at the calibration reference planes while independently tuning the device ...

A nonlinear controller for flutter suppression: from simulation to wind tunnel testing [PDF]
Active control for flutter suppression and limit cycle oscillation of a wind tunnel wing section is presented. Unsteady aerodynamics is modelled with strip theory and the incompressible two-dimensional classical theory of Theodorsen.

The response of a floating ice sheet to an accelerating line load [PDF]
The two-dimensional response of a thin, floating sheet of ice to a line load that accelerates from rest at $t = 0$ to a uniform velocity V for $t \geq T$ is determined through an integral-transform solution of the linearized equations of motion.

Greening Geographical Load Balancing [PDF]
Energy expenditure has become a significant fraction of data center operating costs. Recently, "geographical load balancing" has been suggested to reduce energy cost by exploiting the electricity price differences across regions.

Reliability-based load carrying capacity assessment of bridges using structural health monitoring and nonlinear analysis [PDF]
For assessment of existing bridges, load rating is usually performed to assess the capacity against vehicular loading. Codified load rating can be conservative if the rating is not coupled with the field data or if simplifications are incorporated into ...

An approach to harmonic load- and source-pull measurements for high-efficiency PA design [PDF]
High-efficiency power-amplifier design requires numerous efforts to investigate both input and output harmonic terminations effects. A simplified theoretical approach to clarify the relevance of such terminations is presented here, and design criteria to

Extreme nonlinear dynamics of cantilever beams: effect of gravity and slenderness on the nonlinear modes [PDF]
In this paper, the effect of gravity on the nonlinear extreme amplitude vibrations of a slender, vertically-oriented cantilever beam is investigated. The extreme nonlinear vibrations are modeled using a finite element discretization of the geometrically ...
