This paper presents a practical direct adaptive fuzzy H tracking control (AFHC) approach for a class of uncertain nonlinear systems with unknown control gain functions and external disturbances. A modified output tracking error is defined to eliminate high gain at the control input and to improve transient performance. An ideal control law is developed to eliminate the restriction that the cont...

Whilst this stands to reason, the TeliaSonera case-law adds that there can also be an “exclusionary” abuse when rivals’ margins are “positive”, 2 by virtue, for instance of “reduced profitability”. 3 In other words, there is an infringement of Article 102 TFEU even if rivals maintain the ability to competitively sell their products at prices above costs. We call this the positive margin squeeze...

Four classical laws of black hole thermodynamics are extended from exterior (event) horizon to interior (Cauchy) horizon. Especially, the first law of classical thermodynamics for Kerr-Newman black hole (KNBH) is generalized to those in quantum form. Then five quantum conservation laws on the KNBH evaporation effect are derived in virtue of thermodynamical equilibrium conditions. As a by-produc...

Diagnoses in medicine are often taken to serve as explanations of patients' symptoms and signs. This article examines how they do so. I begin by arguing that although some instances of diagnostic explanation can be formulated as covering law arguments, they are explanatory neither in virtue of their argumentative structures nor in virtue of general regularities between diagnoses and clinical pr...

One of the most attractive aspects of virtual enterprises is their agility: the inherent ability to adapt and evolve in response to changing market conditions. Evolving VirtuE is a formal framework within which such agility can be realized. Through the concepts of enterprise time, activity logging, and log mining, the recent behavior and performance of an enterprise may be studied, and correspo...

IntroductIon David Skyrme (1999) has observed that knowledge workers exploit knowledge generated from business activities and turn it into business opportunities. Technical infrastructures enable knowledge workers and improve knowledge processes (Von Krogh, Ichijo, & Nonaka, 2000). Improving knowledge awareness requires creating a dynamic and generative environment for organizational workers (S...

After centuries of obscurity, the study of the virtues is now one of the most prominent methodologies in ethics. Proponents of this so-called ‘aretaic turn’ differ substantially in the details of their respective proposals, but they tend to see a renewed focus on ethical virtues as a fresh source of insight into problems which have deadlocked more familiar approaches, such as Kantianism or util...
