Feudalism is one of the most studied topics in the field of history but without a consensus on its central characteristics, it remains a slippery concept.

The History of Chinese Feudal Society provides a comprehensive analysis on the rise and fall of feudalism in China. Drawing on a vast resource of archival materials, it is the first study to investigate feudalism in China from the perspective of sociology and to compare feudalism ...

The fundamental lemma due to Willems et al. “A note on persistency of excitation”, Syst. Control Lett., vol. 54, no. 4, pp. 325–329, 2005 plays an important role in system identification and data-driven control. One of the assumptions for the fundamental lemma is that the underlying linear time-invariant system is controllable. In this paper, the fundamental lemma is extended to address system identification for uncontrollable systems. Then, a ...

The interaction of visible and near-infrared light with citrus tissues is of great importance for the design of new optical sensors for fruit quality inspection. In this study, the light propagation through citrus fruit was simulated using the Monte Carlo multi-layered (MCML) technique based on the bulk optical properties (BOP) of citrus tissues. Comparison of the diffuse reflectance profiles from MCML and from the laser scatter images confirmed ...

This work presents the design, optimization and combination of fully pa-rameterized Archimedean spiral cavities (ASCs) as acoustic resonators, in order to achieve perfect absorption at frequencies below 1000 Hz while using a completely modular design. The assembly of two ASCs in the same system is also presented. An optimization is performed and results are verified through Finite Element Analysis (FEA) and validated experimentally for almost ...
