Adaptive control is now finding its way into the marketplace after many years of effort. This paper reviews some ideas used to design adaptive control systems. It covers early ideas which primarily attempt to compensate for gain variations and more general methods like gain scheduling, model reference adaptive control, and self-tuning regulators. It is shown that adaptive control laws can be obtai
The results of an experimental investigation of the effects of the degree of cementation on the mechanical behaviour of a porous artificial rock with crushable grains are presented. The studied material is an analogue of real cemented granular materials, such as pyroclastic weak rocks, carbonate sands, calcarenites and compacted decomposed granite. The present study aims to clarify the role of the
This paper describes a knowledge integration framework for robotics, whose goal is to represent, store, adapt, and distribute knowledge across engineering platforms. The architecture abstracts the components as data sources, where data are available in the AutomationML data exchange format. AutomationML is an on-going standard initiative that aims at unifying data representation and APIs used by e
Vitamin K-dependent protein S is involved in the regulation of blood coagulation. It is a 75-kDa single chain protein with an NH2-terminal gamma-carboxyglutamic acid-containing domain followed by a thrombin-sensitive region and four domains arranged in tandem, each of which is homologous to the epidermal growth factor (EGF) precursor. The NH2-terminal EGF-like domain contains beta-hydroxyaspartic
Labour management in the past has been the studied by researchers from various disciplines and perspectives. Among labour economists and economic historians, there is an emerging current that aims to test hypotheses derived from theories about internal labour markets. So far, most studies have focused on companies whose workforces have been stable or expanding over time. This paper analyzes the in
