In this paper we present a sufficient condition for continuity, called in the paper stability, of Lyapunov exponents of discrete time-varying linear system. Basing on the result we show that Lyapunovâ€¦ (More)

In this technical note, we introduce the concepts of sigma exponent of discrete linear time varying system. It is shown that these exponents describe the possible changes in the Lyapunov exponentsâ€¦ (More)

This note studies the problem of bounds for the Lyapunov exponent of a parameter perturbed system when the perturbation has finite average value. Such a bound is presented in terms of Bohl exponentâ€¦ (More)

In this paper we consider discrete time varying linear systems with matrix coefficients in fixed set and we describe the set of all possible Lyapunov exponents for the system. We describe this set inâ€¦ (More)

Measuring the orientation of the mobile objects is essential for autonomous navigation. In order to construct low cost, miniature aerial vehicles a miniature inertial measurement unit was designedâ€¦ (More)

In case of sequence of matrices we define the characteristic exponent ( ) ( ) N n n âˆˆ Î” = Î” ( ) Î” Î» as a exponent of ( ) ( ) N n n âˆˆ Î” . It is well known [2] that the set of all Lyapunov exponents ofâ€¦ (More)

This paper presents an overview of an object detection and tracking method used in SETh system (Simple Enemy Tracking). Most of visual systems use only motion features to detect and track objects ofâ€¦ (More)
