Indoor Air Quality

Abstract This post presents the results of using the Least-Squares Support Vector Machines (LS-SVMs) framework for estimating CO\(_{2}\) levels at the Holst Center building in the Netherlands. Within the IoT framework, a Wireless Sensor Network (WSN) consisting of seven sensors is currently deployed at different locations on the third floor of the building. A network consisting of seven sensors nodes is currently deployed at different locations in the third floor of the building....

Order Estimation of multidimensional state space models

abstract This post presents a method to identify the order of linear multidimensional (nD) systems based on rank conditions of a recursive hankel matrix. A recursive hankel matrix is a generalization of a classical hankel matrix for multidimensional systems. The estimation method is based on the intersection algorithm for one-dimensional systems. At the basis of this algorithm lies the intersection between past and future data. This subspace contains the information of the sate sequence....
