    Predicting current and future states of rail infrastructure based on existing data and measurements is essential for optimal maintenance and operation of railway systems. Mathematical models are helpful tools for detecting failures and extrapolating current states into...

    We investigate the implementation of model predictive control to the power split problem of a hybrid diesel-electric marine power plant during transient loading. The modeling procedure, the controller design and the experimental validation of the proposed control scheme...

    We introduce a novel analytical framework for the end-to-end (e2e) maximum throughput under delay constraints, namely effective capacity (EC), for multisource and multidestination amplify-and-forward cooperative networks. The network operates in the presence of Rayleigh...

    This paper presents the derivation of a linear model for wheel–rail interaction kinematics at railway crossings. The purpose of this model is to demonstrate the fundamental constraints imposed on a crossing geometry if it should be compatible with a given range of whee...

    In this paper, we analyze the performance of a cognitive amplify-and-forward multi-relay network (CAFMRN) with direct link under the joint impact of transceiver hardware impairments (HIs) and channel estimation errors (CEEs). Herein, we consider hardware distortions ind...

    In this paper, important statistical properties of the double- generalized Gamma (dGG) distribution, a generic modelthat has been used for modeling the double-scattering radio propagation fading conditions, are obtained and investigated. In this context, useful statisti...

    In this paper, we analyze the performance of a cognitive decode-and-forward multi-relay network (CDFMRN) with a direct link under the joint impact of transceiver hardware impairments (HIs) and channel estimation errors. We consider a practical scenario in which the seco...

    In this paper, we study a cooperative vehicle-to-vehicle (V2V) interference-limited communication system with decode-and-forward relaying operating over double-Nakagami (DN) fading channels. This distribution has been proposed as a fading model for scenarios where both ...

    Abstract Mechatronically-guided railway vehicles are of paramount importance in addressing the increasing interest in reducing wheel-rail wear and improving guidance and steering. Conventional passively-guided rail vehicles are limited by the mechanical constraints of t...

    In this paper, we investigate the performance of a spectrum sharing decode-and-forward multiple-relay network (SSDMN) with direct link under the joint impact of two practical and detrimental imperfections, called transceiver hardware impairments (HIs) and channel estima...
