A Procedure for Combining Menstrual Cycle Data*

The Journal of Clinical Endocrinology & Metabolism, 1979
A procedure is presented which overcomes most of the conceptual and statistical problems associated with the combining of data from heterogeneous menstrual cycles for graphical or statistical analyses. This procedure is based upon an initial normalization of the raw data to eliminate extraneous between-cycle variability, followed by the assignment of ...

Combination Open-Cycle Closed-Cycle Systems

Proceedings of the IRE, 1951
The ancient idea of a combination coarse and fine adjustment is shown to be applicable to the design of precision automatic control systems. In the particular class of systems discussed, the coarse adjustment is taken to be a separate element operated by the input, but outside the feedback loop.

Advanced combined-cycle modeling

2013 IEEE Grenoble Conference, 2013
Accurate modeling of combined-cycle power plants is an increasingly important part of more efficient operations of restructured power systems. This paper aims to enhance the existing standard modeling of combined-cycle power plants in real-time generation control, planning and scheduling applications of Energy Management Systems (EMS) and Energy Market

Control System for a Combined Cycle

Volume 4: Heat Transfer; Electric Power; Industrial and Cogeneration, 1989
The paper describes the organization and the architecture of the digital control system for the combined cycle of FIAT Mirafiori power plant. The choice of functions subject to automatic control is connected to the features required such as: - automatic start-up with steam turbine as prime mover; - operation

Dispatchable Solar Combined Cycle

ASME 2017 11th International Conference on Energy Sustainability, 2017
Successful deployment of large amounts of renewable solar and wind energy has created a pressing need for significant additions of grid connected energy storage. Excess renewable generation is increasingly necessitating curtailment or derating of renewable or conventional generators.

Combined Cycle for Hybrid Vehicles

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">Electric hybrid vehicles change the global design of the electrical power on board, but also of the thermal engine. The concept presented is based on recovery and conversion of thermal energy from the engine cooling circuit and the exhaust pipe by a Rankine cycle.

An evaluation of advanced combined cycles

Applied Energy, 2013
Abstract The main objective of this investigation is to identify and assess advanced improvements to the combined cycle such as gas turbine firing temperature, pressure ratio, combustion techniques, intercooling, enhanced blade cooling schemes and supercritical steam cycles that will lead to significant performance improvements in coal based power ...
