Medical ethics and more: Ideal theories, non-ideal theories and conscientious objection
(B M J Publishing Group, 2015-01)
Doing 'good medical ethics' requires acknowledgment that it is often practised in non-ideal circumstances! In this article I present the distinction between ideal theory (IT) and non-ideal theory (NIT). I show how IT may ...
A teoria da justiça como equidade e as ações afirmativas
(Universidade Federal de Santa MariaBrasilFilosofiaUFSMPrograma de Pós-Graduação em FilosofiaCentro de Ciências Sociais e Humanas, 2017-03-06)
John Rawls conceives society as a cooperation system. To govern this system, he developed the theory of justice as fairness (JAF). His theory, from its emergence in the early 1970s to the present, has been commonly ...
On non-linear dynamics and control designs applied to the ideal and non-ideal variants of the Fitzhugh-Nagumo (FN) mathematical model
(Elsevier B.V., 2009-03-01)
The Fitzhugh-Nagumo (FH) mathematical model is considered a simplification of the Hodgkin-Huxley (HH) model. This paper analyzes the non-linear dynamics of the Fitzhugh-Nagumo (FN) mathematical model, and still presents ...
On the existence and stability of periodic orbits in non ideal problems: General results
In this work, motivated by non-ideal mechanical systems, we investigate the following O.D.E. ẋ = f (x) + εg (x, t) + ε2g (x, t, ε), where x ∈ Ω ⊂ ℝn, g, g are T periodic functions of t and there is a 0 ∈ Ω such that f (a ...
A non-ideally excited pendulum controlled by SDRE technique
In this work, the perturbation theory is applied to the analysis of an electromechanical pendulum system. The frequency response behavior of the system is studied, and the existence of unstable poles is detected using the ...
Stick-slip chaos in a non-ideal self-excited system
In engineering practical systems the excitation source is generally dependent on the system dynamic structure. In this paper we analyze a self-excited oscillating system due to dry friction which interacts with an energy ...
