Tuberculosis Control: A New Approach

Abstract

Texas 75083-3836 U.S.A., fax +1-972-952-9435. AbstractAlthough the incidence of TB is receding in western countries, several factors such as resistance to antibiotics and HIV epidemic have worsened the situation in many low-income countries. Meanwhile, the globalization process has increased the frequency of travel and contacts between individuals from low and high incidence areas, therefore increasing the exposure of non-infected individuals. This is especially true for some of the oil and gas operations e.g. offshore, where the layout of the living quarters is propitious for TB transmission. Although rare, any active case of TB occurring offshore has the potential for a high impact on operations. Recently in spite of a comprehensive screening program in place for high incidence country national employees, an active case occurred on a platform in the Gulf of Mexico. That case triggered a search for a better screening tool to ensure that no detectable active TB cases enter the work place. This paper will describe our findings.

Design and test of feedback control loops with a generic multipurpose tokamak plasma discharges flight simulator

“…-To begin with a simplified linear model providing the plasma boundary gaps (8 gaps) to the wall as a function of the PF coils current (12 currents in the more general case) was derived by linearization around a given reference equilibrium using the CEDRES++ free boundary equilibrium code [1,7,8]. -Then the feedback control design was performed under Scicoslab (Fig.…”

“…Tools structuring the Generic Multi Purpose plasma Flight Simulator (blue items sketch the plant control systems including the plasma itself; green items account for the ITM-TF tools; the pink items account for the interfaces that have to be developed) they mainly consist in switches between the simulation and the tokamak world allowing the operate the GMFS in different modes such as fully simulated or hardware in the loop[1,2].
