Quantitative stability for the first Dirichlet eigenvalue in Reifenberg flat domains in RN
(2010)In this paper we prove that if Ω and Ω′ are close enough for the complementary Hausdorff distance and their boundaries satisfy some geometrical and topological conditions then| λ1 - λ1′ | ≤ C | Ω △ Ω′ |frac(α, N) where λ1 ...

Robust adaptive control of minimum phase non-linear systems
(1996)We show that an adaptive input/output feedback linearization control scheme for minimum phase nonlinear systems is robust with respect to unstructured plant uncertainties such as unmodelled dynamics and disturbances provided ...

Robust platoon-stable controller design for autonomous intelligent vehicles
(IEEE, 1994)A new variable structure longitudinal controller is designed and analyzed for an autonomous intelligent vehicle. The proposed controller not only guarantees individual vehicle stability but also platoon stability. Moreover, ...

A scalable iterative convex design for nonlinear systems
(2012)A recently developed control scheme for approximately optimal control of nonlinear systems is the so-called Convex Control Design (ConvCD) methodology, that transforms the control problem of generic nonlinear systems into ...

Solutions for a nonlocal conservation law with fading memory
(2007)Global entropy solutions in BV for a scalar nonlocal conservation law with fading memory are constructed as the limits of vanishing viscosity approximate solutions. The uniqueness and stability of entropy solutions in BV ...

Stability margins in adaptive mixing control via a Lyapunov-based switching criterion
(2012)In all classes of linear adaptive control that involve switching or not there is no guarantee that after the switching stops or the adaptation is switched off the resulting closed loop linear time invariant system is stable ...

Stability of the annular Poiseuille flow of a Newtonian liquid with slip along the walls
(2008)The annular Poiseuille flow of a compressible Newtonian fluid is studied assuming that slip occurs along the wall. Different slip models relating the wall shear stress to the slip velocity are employed. In the case of ...

(2009)The annular Poiseuille flow a Newtonian fluid is studied assuming that slip occurs along the walls. Different slip models relating the wall shear stress to the slip velocity are employed. In the case of non-monotonic slip ...

Stability Subtypes of Callous–Unemotional Traits and Conduct Disorder Symptoms and Their Correlates
(Springer New York LLC, 2016)Callous–unemotional traits and conduct disorder symptoms tend to co-occur across development, with existing evidence pointing to individual differences in the co-development of these problems. The current study identified ...

Stable theories for logic programs
(Publ by MIT Press, 1991)We define a class of theories associated to any normal logic program, called stable theories, based on a notion of stable negative hypotheses. This stability of hypotheses is motivated directly from the intuitive understanding ...

Stochastic linear programs with restricted recourse
(1997)Stochastic programs with recourse provide an effective modeling paradigm for sequential decision problems with uncertain or noisy data, when uncertainty can be modeled by a discrete set of scenarios. In two-stage problems ...

Studies on the interaction of olive cake and its hydrophylic extracts with polyvalent metal ions (Cu(II), Eu(III)) in aqueous solutions
(2009)The paper presents and discusses the chemical affinity of two different forms of natural organic matter (e.g. in solid (SOM) and soluble form (DOM)) for Cu2+ and Eu3+ ions. In the this study SOM is represented by olive ...

Three-dimensional direct numerical simulations of hydrodynamic and magnetohydrodynamic flows over an obstacle in a confined geometry
(Πανεπιστήμιο Κύπρου, Πολυτεχνική Σχολή / University of Cyprus, Faculty of Engineering, 2012-12)Στην παρούσα διατριβή παρουσιάζεται η υδροδυναμική και μαγνητοϋδροδυναμική ροή που αναπτύσσεται γύρω από ένα κύλινδρο κυκλικής διατομής, σε γεωμετρίες περιορισμένες από σταθερά τοιχώματα. Η επίδραση του περιορισμού της ...

Time-dependent compressible extrudate-swell problem with slip at the wall
(1994)We solve the time-dependent compressible Newtonian extrudate-swell problem with slip at the wall, in an attempt to simulate the stick-slip extrusion instability. An arbitrary nonlinear slip model relating the shear stress ...

The time-independent, compressible Poiseuille and extrudate-swell flows of a Carreau fluid with slip at the wall
(2003)We solve the time-dependent, compressible Poiseuille and extrudate-swell flows of a shear-thinning fluid that obeys the Carreau constitutive model, using finite elements in space and a fully-implicit scheme in time. Slip ...

Using the Milliken Moment Method and dynamic simulation to evaluate vehicle stability and controllability
(2008)The Milliken Moment Method (MMM) effectively organises kinematically constrained vehicle test results. The authors present a method for evaluating vehicle handling
