(author)Accurate estimation of Brake Specific Fuel Consumption (BSFC) is required to enable on-line optimization of real-world fuel efficiency of diesel engines. This work aims to develop a BSFC estimation method which is accurate enough for an adaptive controller for on-line engine optimization, e.g., using Extremum Seeking. In this paper two different...article 2018

Jorguseski, L. (author), Zhang, H. (author), Chrysalos, M. (author), Golinski, M. (author), Toh, Y. (author)This study investigates the feasibility of using Long Term Evolution (LTE), for the real-time state estimation of the smart grids. This enables monitoring and control of future smart grids. The smart grid state estimation requires measurement reports from different nodes in the smart grid and therefore the uplink LTE radio delay performance is...conference paper 2017

(author)Driver distraction is a leading cause of crashes. The introduction of in-vehicle technology in the last decades has added support to the driving task. However, in-vehicle technologies and handheld electronic devices may also be a threat to driver safety due to information overload and distraction. Adaptive in-vehicle information systems may be a...conference paper 2017

Noack, B. (author), Sijs, J. (author), Reinhardt, M. (author), Hanebeck, U.D. (author)In distributed and decentralized state estimation systems, fusion methods are employed to systematically combine multiple estimates of the state into a single, more accurate estimate. An often encountered problem in the fusion process relates to unknown common information that is shared by the estimates to be fused and is responsible for...article 2017

(author), Dusek, U. (author)Radiocarbon analysis is a widely-used tool for source apportionment of aerosol particles. One of the big challenges of this method, addressed in this work, is to isolate elemental carbon (EC) for 14C analysis. In the first part of the study, we validate a two-step method (2stepCIO) to separate total carbon (TC) into organic carbon (OC) and EC...article 2017

(author)In this work a Tire State Estimator (TSE) is developed and validated using data from a tri-axial accelerometer, installed at the inner liner of the tire. The Flexible Ring Tire (FRT) model is proposed to calculate the tire deformation. For a rolling tire, this deformation is transformed into tangential and radial accelerations of a point on the...conference paper 2016

Naus, H.W.L. (author)Geolocation based on time differences of arrival measured by three sensors is studied. Closed-form analytical solutions are derived, even for the cases where one or more sensors are not located on the earth. Exploiting four sensors, full three-dimensional localisation is achieved as well. These numbers of sensors are minimal. The analytical...article 2016

Dragt, R.C. (author), Maljaars, J. (author), Tuitman, J.T. (author), Salman, Y. (author), Otheguy, M.E. (author)Retardation is a load sequence effect, which causes a reduced fatigue crack growth rate after an overload is encountered. Retardation can be cancelled when the overload is followed by an underload. The net effect is beneficial to the fatigue lifetime of Offshore Wind Turbines (OWTs). To be able to take this into account, computationally...conference paper 2016

Calvert, S.C. (author), Snelder, M. (author)Traffic is affected by a wide range of variables. An influential and commonly occurring variable on traffic flow is the weather. Weather conditions affect both traffic demand as well as road capacity and in doing so also affect the traffic fluency, or rather the ability of traffic to maintain a certain level-of-service. In this contribution it...article 2016

Schmeitz, A.J.C. (author), Alirezaei, M. (author)With higher level of vehicle automation, it becomes increasingly important to know the maximum possible tyre forces during normal driving. An interesting method in this respect is estimating the tyre-road friction from the resonance in the wheel speed signal, excited by road roughness. A simulation environment using the MFSwift tyre model is...article 2016
