The Influence of Human Walking Activities on the Doppler Characteristics of Non-stationary Indoor Channel Models
(Chapter; Peer reviewed, 2019)This paper analyzes the time-variant (TV) Doppler power spectral density of a 3D non-stationary fixed-to-fixed indoor channel simulator after feeding it with realistic trajectories of a walking person. The trajectories of ... -

Multi-layer intrusion detection system with ExtraTrees feature selection, extreme learning machine ensemble, and softmax aggregation
(Journal article; Peer reviewed, 2019)Recent advances in intrusion detection systems based on machine learning have indeed outperformed other techniques, but struggle with detecting multiple classes of attacks with high accuracy. We propose a method that works ... -

RF-Based Human Activity Recognition : A Non-stationary Channel Model Incorporating the Impact of Phase Distortions
(Chapter; Peer reviewed, 2019)This paper proposes a non-stationary channel model that captures the impact of the time-variant (TV) phase distortion caused by hardware imperfections. The model allows for studying the spectrogram of in-home radio channels ... -

Prospective mathematics teachers? self-referential metaphors as indicators of the emerging professional identity
(Peer reviewed; Journal article, 2019)Ideals play a key role in a student teachers’ identity work. They form targets to strive for and a mirror for reflection. In this paper, we examine Finnish mathematics student teachers’ metaphors for the teacher’s role ... -
FMU-proxy : A Framework for Distributed Access to Functional Mock-up Units
(Journal article; Peer reviewed, 2019)The main goal of the Functional Mock-up Interface (FMI) standard is to allow simulation models to be shared across tools. To accomplish this, FMI relies on a combination of XML-files and compiled C-code packaged in a zip ... -
