Because of the evolution of the World Wide Web, the fields of intelligent agents and multi-agent systems have become a focus of interest. This intensive research has originated several frameworks, or toolkits, that are used by the researchers to develop Internet agent-based systems. Their aim is to help the designers and engineers to build complex systems(More)
This article analyzes the factors associated with vulnerability of the Ashaninka, the most populous indigenous Peruvian Amazonian people, to tuberculosis (TB). By applying a human rights-based analytical framework that assesses public policy against human rights standards and principles, and by offering a step-by-step framework for a full assessment of(More)
DISCUSSION With the advent of ALPPS, it became possible to achieve hypertrophy of FLR at 75% on average, in a quick way and over a mean period of nine days 4. However, the authors reported high morbidity and mortality rates, particularly with regard to the initial surgery, with high rates of biliary fistula and intraoperative bleeding. In our case, with the(More)
This paper deals with issues of actuator fault tolerant PID controllers. It is studied, how residual generation based on a linear model is affected by the robust properties of a PID used in feedback. To get the sensitivity of the residual with respect to faults and to keep the robustness of the controller, a scheme is proposed with a non linear residual(More)
