Wave Interaction Theory and LFC
1992The complex high Reynolds number flows over modern swept wings can support at least three types of hydrodynamic instability; namely Gortler, Crossflow, and Tollmien-Schlichting instability mechanisms which can all cause transition to turbulence in many flows of practical importance.

Comparison of three different metallization concepts for LFC cells
2010Laser fired contacts (LFC) are a well known technique to apply the rear side electrode on dielectrically passivated solar cells. Thereby, the aluminum on top of the passivation is locally heated by means of single laser pulses and subsequently alloyed into the silicon.

Single and two area LFC using RBF
2015 International Conference on Recent Developments in Control, Automation and Power Engineering (RDCAPE), 2015The control of operating frequency is of utmost importance in the power system operation and control from stability point of view. Conventionally load frequency control is done by employing PI controllers. Immediate control of system frequency oscillation is very vital to avoid hazardous conditions.

Quantum evolution of a qubit state with decoherence and LFC
Modern Physics Letters B, 2016We study the Rabi oscillation of two-level system in double quantum dots, and found that the Rabi oscillation considering decoherence rate is a cycle attenuated oscillation when the qubit energy asymmetry [Formula: see text] ([Formula: see text] is the qubit energy asymmetry). The peak of Rabi oscillation alternatively changes in the case of the qubit

A literature survey on LFC in a deregulated electricity environment
World Review of Science, Technology and Sustainable Development, 2018This paper deals with an exhaustive literature survey on load frequency control (LFC) of a deregulated electricity environment for different market scenarios for various power generating units such as thermal, hydro, wind, diesel, and hybrid power systems. Load frequency controls employ conventional controllers such as I, PI, PID controllers as well as
