Abrupt and incipient fault isolation of nonlinear uncertain systems
(2000)This paper presents a robust fault diagnosis scheme for abrupt and incipient faults in nonlinear uncertain dynamical systems. A detection and approximation estimator is used for online health monitoring. Once a fault is ...

Article
Autonomous intelligent cruise control using front and back information for tight vehicle following maneuvers
(1999)During manual driving, most human drivers often use information about the speed and position of the preceding and following vehicles in order to adjust the position and speed of their vehicles. The purpose of this paper ...

Article
Backward difference formulae for Kuramoto–Sivashinsky type equations
(2017)We analyze the discretization of the periodic initial value problem for Kuramoto–Sivashinsky type equations with Burgers nonlinearity by implicit–explicit backward difference formula (BDF) methods, establish stability and ...

Article
Comparing intracellular stability and targeting of sulfobetaine quantum dots with other surface chemistries in live cells
(2012)The in vivo labeling of intracellular components with quantum dots (QDs) is very limited because of QD aggregation in the cell cytoplasm and/or QD confinement into lysosomal compartments. In order to improve intracellular ...

Decentralized fault accommodation of a class of interconnected nonlinear systems using an adaptive approximation approach
(2009)This paper presents a decentralized adaptive approximation design for the fault tolerant control of interconnected subsystems. We consider faults that occur in the subsystems local dynamics as well as in the interconnection ...

Decentralized Reconfigurable Control for LargeScale Systems with Application to a Segmented Telescope TestBed
(2003)Designing a decentralized reconfigurable control (DRC) system is considered for largescale systems. The objective of the DRC system is to achieve performance requirements under normal and sensor failure situations. The ...

Article
Existence and stability of traveling discrete shocks
(1997)We are concerned with existence and stability questions for finite difference schemes approximating solutions of scalar conservation laws with shocks. A suitable model for the study of the artifacts created by these schemes ...

Flow instabilities of HerschelBulkley fluids
(2003)We investigate numerically the interactions of twodimensional jets of Bingham plastic and HerschelBulkley fluids with a vertical surface at a distance from the die exit. This problem simulates the early stages of filling ...

Article
Global asymptotic stability of maxmin congestion control schemes
(2017)A number of congestion control schemes which adopt the maxmin fairness criterion and do not require maintenance of per flow states within the network have been proposed in the literature. The establishment of global ...

Article
The impact of network structure on the stability of greedy protocols
(2003)A packetswitching network is stable if the number of packets in the network remains bounded at all times. A very natural question that arises in the context of stability and instability properties of such networks is how ...

Longtime Stability of Mg2(SiSnGe)  Based Thermoelectrics Under Large Temperature Gradient Conditions
(Elsevier Ltd, 2015)We study the thermoelectric properties and stability of Mg2(SiSnGe) composite, prepared by a combination of ball milling process and heating treatment followed by Spark Plasma Sintering and densification. The goal of ...

Article
LQG optimality and separation principle for general discrete time partially observed stochastic systems over finite capacity communication channels
(2008)This paper is concerned with control of stochastic systems subject to finite communication channel capacity. Necessary conditions for reconstruction and stability of system outputs are derived using the Information ...

On optimal performance for linear timevarying systems
(2004)In this paper we consider the optimal disturbance attenuation problem and robustness for linear timevarying (LTV) systems. This problem corresponds to the standard optimal H ∞ problem for LTI systems. The problem is ...

Article
On the combined effects of slip, compressibility, and inertia on the Newtonian extrudateswell flow problem
(2013)We solve both the planar and axisymmetric extrudateswell flows of a compressible Newtonian liquid with Navier slip at the wall, using the finiteelement method in space and a fullyimplicit finitedifference scheme in ...

Article
On the stability of compositions of universally stable, greedy contentionresolution protocols
(2002)A distinguishing feature of today’s largescale platforms for distributed computation and communication, such as the Internet, is their heterogeneity, predominantly manifested by the fact that a wide variety of communication ...

Article
On the stability of the simple shear flow of a JohnsonSegalman fluid
(1998)We solve the timedependent simple shear flow of a JohnsonSegalman fluid with added Newtonian viscosity. We focus on the case where the steadystate shear stress/shear rate curve is not monotonic. We show that, in addition ...
