Data Transmission Over Networks for Estimation and Control (2009)
Gupta, Vijay, Dana, Amir F., Hespanha, Joao P., Murray, Richard M., Hassibi, Babak
We consider the problem of controlling a linear time invariant process when the controller is located at a location remote from where the sensor measurements are being generated. The communication...
Error Scaling Laws for Linear Optimal Estimation from Relative Measurements (2009)
Barooah, Prabir, Hespanha, Joao P.
We study the problem of estimating vector-valued variables from noisy "relative" measurements. This problem arises in several sensor network applications. The measurement model can be expressed in...
Computation of L 2-Induced Norms of Switched Linear Systems # (2007)
In this paper we compute the L2-induced norm of a switched linear system when the interval between consecutive switchings is large. The motivation for this problem is the application of robust...
Nonlinear Observability Notions and Stability of Switched Systems (2003)
Joao P. Hespanha, David Angeli, Daniel Liberzon, Eduardo D. Sontag
This paper proposes several definitions of observability for nonlinear systems and explores relationships among them. These observability properties involve the existence of a bound on the norm of...
Computational Complexities of Honey-pot Searching with Local Sensory Information (2003)
Bhaskar Dasgupta, Joao P. Hespanha, Eduardo Sontag
In this paper we investigate the problem of searching for a hidden target in a bounded region of the plane, by an autonomous robot which is only able to use limited local sensory information. We...
Extending LaSalle’s invariance principle to switched linear systems (2001)
In this paper we extend LaSalle's Invariance Principle to certain classes of switched linear systems. In particular we illustrated how to prove asymptotic stability using multiple Lyapunov...
Analysis of a TCP hybrid model (2001)
Stephan Bohacek, Joao P. Hespanha, Junsoo Lee, Katia Obraczka
In this paper we use hybrid systems to model and analyze the transient and steady-state behavior of multiple TCP flows that share a single common bottleneck link. The main contributions of this paper...
Probabilistic pursuit-evasion games: A one-step Nash approach (2000)
Joao P. Hespanha, Maria Prandini, Shankar Sastry
This paper addresses the control of a team of autonomous agents pursuing a smart evader in a non-accurately mapped terrain. By describing the problem as a partial information Markov game, we are able...
Eigenfaces vs. Fisherfaces: Recognition Using Class Specific Linear Projection (1997)
Peter N. Belhumeur, Joao P. Hespanha, P. Hespanha, David J. Kriegman
We develop a face recognition algorithm which is insensitive to large variation in lighting direction and facial expression.
