This is the first part of a work on intelligent type control of Heating, Ventilating and AirConditioning (HVAC) systems. The study is performed from the perspective of giving a unitary control method to ensure high energy efficiency and air quality improving. To illustrate the proposed HVAC control technique, in this first part it is considered as benchmark(More)
Menadione (MD) is an effective cytotoxic drug able to produce intracellularly large amounts of superoxide anion. Quercetin (QC), a widely distributed bioflavonoid, can exert both antioxidant and pro-oxidant effects and is known to specifically inhibit cell proliferation and induce apoptosis in different cancer cell types. We have investigated the relation(More)
Over the past ten years, fuzzy logic, as main component of artificial intelligence, has significantly influenced the design of controlled systems. Focusing on applied mathematics field, the paper proposes an antilock-braking system (ABS) for a Romanian military jet. It is well known that in the ABS brake, the control is considered from a " panic stop "(More)
Following previous work, we investigated in more detail the relationship between apoptosis and delayed luminescence (DL) in human leukemia Jurkat T cells under a wide variety of treatments. We used menadione and hydrogen peroxide to induce oxidative stress and two flavonoids, quercetin, and epigallocatechin gallate, applied alone or in combination with(More)
The obtaining of control law for an advanced four-dimensional, nonlinear electrohydraulic servo mathematical model is the main contribution of the paper. This control law ensures the asymptotic stability of references tracking by constructing a Control Lyapunov Function (CLF) on the errors concerning the state variables and theirs desired values. An(More)
The present paper addresses the problem of flutter prevention for weakly damped aeroelastic wing structures by means of the primary flight controls servos. In fact, an active control for a typical section in unsteady incompressible flow is thought. As mathematical model, a linear system with structured uncertainty is obtained. Firstly, the optimal linear(More)
