Sommario/riassunto |

Based on information theory, a number of entropy measures have been proposed since the 1990s to assess systems' irregularity, such as approximate entropy, sample entropy, permutation entropy, intrinsic mode entropy, and dispersion entropy, to cite only a few. Among them, sample entropy has been used in a very large variety of disciplines for both univariate and multivariate data. However, improvements to the sample entropy algorithm are still being proposed because sample entropy is unstable for short time series, may be sensitive to parameter values, and can be too time-consuming for long data. At the same time, it is worth noting that sample entropy does not take into account the multiple temporal scales inherent in complex systems. It is maximized for completely random processes and is used only to quantify the irregularity of signals on a single scale. This is why analyses of irregularity-with sample entropy or its derivatives-at multiple time scales have been proposed to assess systems' complexity. This Book presents contributions related to new and original research based on the use of sample entropy or its derivatives. |

Sommario/riassunto |
|
High and rising energy and fossil fuel prices and the requirement to reduce CO2 emissions are strong drivers for innovative technical solutions. Highly energy intensive industries, like cement, are looking rigorously for solutions to reduce their dependence on energy costs. One untapped energy resource is the vast amount of low and medium temperature heat lost in cement plants and processes today. We will show our technical solution to convert low temperature waste heat into electricity and provide answers to the following key questions: What are possible heat sources in the cement process that can be used? How does our new type of small ORC power plant convert the waste heat into electrical power, without using additional primary energy or generating CO2 or other emissions? What are the benefits of the waste heat recovery system? What is the impact on energy efficiency and operational costs?. |
