Mentink, P. (author), Seykens, X. (author)Complying to both the increasingly stringent pollutant emissions as well as (future) GHG emission legislation - with increased focus on in-use real-world emissions - puts a great challenge to the engine/aftertreatment control development process. Control system complexity, calibration and validation effort has increased dramatically over the...conference paper 2019

Jorguseski, L. (author), Zhang, H. (author), Dijkstra-Soudarissanane, S. (author), Golinski, M. (author)This study investigates the feasibility of using Long Term Evolution (LTE) cellular networks for the real-time smart grid state estimation. The smart grid state estimation requires measurement reports from different nodes installed in the smart grid. Therefore, the uplink LTE radio delay performance is selected as key performance indicator for...article 2019

(author)Injury rates are a thing of the past: building better performance measures for better conversations to provoke change. The Oil & Gas industry has measured safety performance using Injury frequency rates for the last 40 years. Industry thinking is based on the premise that: if we do not have injuries then we are safe, and if we have injuries we...conference paper 2018

Dieteren, G. (author), Bigaj-van Vliet, A.J. (author), Yang, Y. (author), Sangers, A. (author)In-situ load testing of reinforced concrete (RC) structures is often performed to confirm the presence of the required resistance for the intended use (Conformity Load Testing) or to support the assessments of the residual capacity by models (Supplementary Load Testing for Condition Assessment). When performing an in-situ load test, one of the...conference paper 2017

(author)Sweet spot identification in underexplored shale gas basins needs to be based on a limited amount of data on shale properties in combination with upfront geological characterization and modelling, because actual production data is usually absent. Multidisciplinary reservoir characterization and integration of modelling approaches can aid initial...article 2015

Gallis, R. (author), Zwetsloot, G.I.J.M. (author)High Reliability Organizations (HRO’s) are organizations that constantly face serious and complex (safety) risks yet succeed in realising an excellent safety performance. In such situations acceptable levels of safety cannot be achieved by traditional safety management only. HRO’s manage safety risks in a specific way, supported by an associated...other 2014

Brasjen, B.J. (author), Veltin, J. (author), Hansen, J.H. (author)The present work focuses on experimental evidence of slug mitigation via various devices. The slug mitigation potential of a number of mixers was tested using a laboratory scale air/water setup to compare their effect on the incoming slugs just upstream of the separator inlet. Dedicated methods and key performance indicators were developed to...conference paper 2014

Nooij, P.N.C. (author), Theil, A. (author)Blake chart computations are widely employed to rank detection coverage capabilities of competitive search radar systems. Developed for comparable 2D radar systems with a mechanically rotating reflector antenna, it was not necessary to regard update rate and plot quality in Blake's chart. To characterize the system's critical awareness, the...conference paper 2014

It is shown that using the process gain matrix, the dryer energy efficiency can be reliably calculated with conditions for simultaneous controllability improvement established. By incorporating a drying...article 2013

Steering behavior was used as a measure of control performance. The experimental task was a slalom maneuver in which the velocity of the car was limited to 70 km/h. Subjective and objective variables were measured. The paper...article 2010
