This note examines the robustness properties of the nonlinear PI control method to ignored actuator dynamics. It is proven that global boundedness and regulation can be achieved for sector bounded nonlinear systems with unknown control directions if the actuator dynamics are sufficiently fast and the nonlinear PI control gain is chosen from a subclass of the Nussbaum function class. Simulation ...

this essay examines greetings as one of the elements of politeness in a nigerian community and how it influences the cultural characteristics of the people. to analyze, this essay makes use of speech act theory and politeness principle and also considers the pragmatic context in analyzing different types of greetings such as condolences, departure and arrival, rejoicing, daily greetings, casual...

in the present paper, the aeroelastic stability of helicopter rotor blade is determined using aeroelastic frequency response function. the aeroelastic model of blade is obtained by combining dowell - hodges beam model with loewy unsteady aerodynamic theory which considers an unsteady wake beneath the rotor. equations are formed and aeroelastic frequency response functions are obtained by invert...

In this paper, the flexural response of functionally graded plates with porosities is investigated using a novel higher order shear deformation theory, which considers the influence of thickness stretching. This theory fulfills the nullity conditions at the top and bottom of the plate for the transverse shear stresses, thus avoids the need of a shear correction factor. The effective material pr...

Thoughtful discussions of the value judgements employed in the course of designing development, such as those exemplified in Nussbaum and Glover’s volume Women Culture and Development, are rapidly proliferating, such that even the World Bank’s president asserted ‘that the World Bank’s central mission is to meld economic assistance with spiritual, ethical, and moral development’ (World Bank 1996...

Abstract As the world economy has for better or worse become more and dependent on financial markets, a rethinking of role finance in both theory practice is necessary. I argue that such requires new look at theories philosophical kind. In effect, as Martha Nussbaum claims, if absence philosophy economics arguably one main reasons flaws certain economic theories, our systems. this paper discuss...

according to several reports, in spite of huge investment on customer relationship management (crm), risk of implementing such projects is high. one of failure factors is having no method to assess crm success comprehensively. nowadays, classic financial methods are common ways for assessing marketing and crm initiatives. but, the mentioned models are unsuitable to assess investments like crm t...

In this paper, the adaptive neural network event-triggered tracking problem is investigated for a class of uncertain switched nonlinear systems with unknown control direction and average dwell time switching. To reduce communication traffic, an event-triggering mechanism based on error explored in controller-to-actuator channel. Additionally, minimal approximation technology, which designs virt...

The U.S. Food and Drug Administration is considering restricting or banning morcellation in minimally invasive hysterectomies and myomectomies (removal of fibroids) because of new reports of higher incidence of undiagnosed sarcoma in women undergoing these procedures. Research now links morcellation to the spread, or upstaging, of undetectable gynecological cancers. In July, FDA convened a 2-da...
