Global Systems for Mobile Position Tracking Using Kalman and Lainiotis Filters
Assimakis, N.; Adam, M. (2014)We present two time invariant models for Global Systems for Mobile (GSM) position tracking, which describe the movement in x-axis and y-axis simultaneously or separately. We present the time invariant filters as well as ... -
Golden section, Fibonacci sequence and the time invariant Kalman and Lainiotis filters
Adam, M.; Assimakis, N.; Farina, A. (2015)We consider the discrete time Kalman and Lainiotis filters for multidimensional stochastic dynamic systems and investigate the relation between the golden section, the Fibonacci sequence and the parameters of the filters. ... -
Inversion free algorithms for computing the principal square root of a matrix
Assimakis, N.; Adam, M. (2014)New algorithms are presented about the principal square root of an n×n matrix A. In particular, all the classical iterative algorithms require matrix inversion at every iteration. The proposed inversion free iterative ... -
Lainiotis filter, golden section and Fibonacci sequence
Assimakis, N.; Adam, M.; Triantafillou, C. (2013)The relation between the discrete time Lainiotis filter on the one side and the golden section and the Fibonacci sequence on the other is established. As far as the random walk system is concerned, the relation between the ... -
A new author's productivity index: p-index
Assimakis, N.; Adam, M. (2010)In this paper a new author's productivity index is introduced, namely the golden productivity index. The proposed index measures the productivity of an individual researcher evaluating the number of papers as well as the ... -
Nonrecursive solution for the discrete algebraic Riccati equation and X plus A*X-1 A = L
Adam, M.; Assimakis, N. (2015)In this paper, we present two new algebraic algorithms for the solution of the discrete algebraic Riccati equation. The first algorithm requires the nonsingularity of the transition matrix and is based on the solution of ... -
Optimal decentralized Kalman filter and Lainiotis filter
Assimakis, N.; Adam, M.; Koziri, M.; Voliotis, S.; Asimakis, K. (2013)A method to implement the optimal decentralized Kalman filter and the optimal decentralized Lainiotis filter is proposed; the method is based on the a priori determination of the optimal distribution of measurements into ... -
Optimal distributed kalman and lainiotis filters: Optimal uniform distribution of measurements into local processors
Assimakis, N.; Adam, M.; Koziri, M.; Voliotis, S. (2009)A method to implement the optimal distributed Kalman and Lainiotis filters is proposed. The method is based on the a-priori determination of the optimal uniform distribution of the measurements into parallel processors, ... -
Riccati equation solution method for the computation of the extreme solutions of X + A* X-1 A = Q and X - A* X-1 A = Q
Adam, M.; Sanida, F.; Assimakis, N.; Voliotis, S. (2009)Algebraic and recursive methods for computing the extreme solutions of the matrix equations X + A* X-1 A = Q and X - A* X -1 A = Q are presented in this paper. The proposed algorithms are based on the solution of the ... -
Towards the mathematic formalization of parametric generalized cylinders and initial results in modeling 3D image data
Kechriniotis, A. I.; Delibasis, K. K.; Tsonos, C.; Assimakis, N.; Asvestas, P. (2009)Generalized cylinders (GCs) have been proposed in computer vision for object modeling in two dimensional images. However approaches so far have not investigated closed form solutions, based on a formal generic definition ...
