Closed-Loop Fault-Tolerant Control for Uncertain Nonlinear Systems
We are designing, perhaps for the first time, closed-loop fault-tolerant control for uncertain nonlinear systems. Our solution is based on a new...

Remarks on Moving Horizon State Estimation with Guaranteed Convergence
In this paper, a moving horizon state estimation scheme is proposed. The scheme is inspired by combining the system-theoretic concept of...
-
On Invariant Observers
A definition of invariant observer and compatible output function is proposed and motivated. For systems admitting a Lie symmetry-group G of...

Model-based Nonlinear Tracking Control of Pressure Swing Adsorption Plants
Pressure swing adsorption (PSA) processes are used for the separation and purification of gas mixtures. PSA plants are composed of several fixed-bed...

8 Entropy Production of Atmospheric Heat Transport
We examine the rate of entropy produced by the atmospheric general circulation and the hypothesis that it adjusts itself towards a macroscopic state...
-
A Imperfection Data Bank
For the stochastic modeling of geometric imperfections as described in Sec. 12.1, a database [5] has been available. This database provides...

10 Thermodynamics of the Ocean Circulation: A Global Perspective on the Ocean System and Living Systems
In this chapter, we investigate thermodynamics in a global-scale open ocean circulation and discuss the physical properties of “living systems”, that...

16 Temperature, Biogenesis, and Biospheric Self-Organization
We argue that the biosphere has evolved deterministically as a selforganized system, given the initial conditions of the Sun-Earth system. With...

7 Rational Treatment of Uncertainties
Structural analysis up to this date, generally is still based on a deterministic conception. Observed variations in loading conditions, material...

4 Finite Element Method
In this chapter, the fundamentals of the displacement-based finite element method are reiterated in a concise form, details can be found in a number...

9 Direct Monte Carlo Simulation
The evaluation of the stochastic response by the Monte Carlo simulation technique is a powerful method for highly nonlinear systems as well as for...

Parametric Spectral Estimation and Data Whitening
The knowledge of the noise Power Spectral Density is fundamental in signal processing for the detection algorithms and for the analysis of the data....

18 Insights from Thermodynamics for the Analysis of Economic Processes
The laws of thermodynamics constrain transformation of materials and energy, and thus have implications for economic processes. This paper provides...

1 Entropy Production by Earth System Processes
Degradation of energy to lower temperatures and the associated production of entropy is a general direction for Earth system processes, ranging from...

11 Random Vibrations of Large Finite Element Systems
The basic idea for the computation of the stochastic response is based on the Karhunen-Loève expansion of the stochastic loading. For each Karhunen-...

15 Coupled Evolution of Earth’s Atmosphere and Biosphere
Earth’s climate has remained conducive to life for more than 3.5 billion years, probably because of higher concentrations of CO2 and CH4 greenhouse...

5 Non-Linear Static Analysis
The state of the art in the capability to predict the stability behavior of shell structures refers to areas such as asymptotic analysis [69] and...

3 Spectral Analysis of Finite Dimensional Operators
A great number of engineering problems can be viewed as an input to output map**, as shown in Fig. 3.1, where the system represents the law for the...

12 Entropy Production in the Planetary Context
In this paper I review some applications of nonequilibrium thermodynamics to planetary science. Of particular importance are the horizontal and...

Padé Approximants
The frequent situation one encounters in applied science is the following: the information we need is contained in values, or some features of the...
