Chekkala, Aashlesha (author), Atasoy, M. (author), Williams, Cecilia (author), Cetecioglu, Zeynep (author)An approach based on wastewater epidemiology can be used to monitor the COVID-19 pandemic by assessing the gene copy number of SARS-CoV-2 in wastewater. In the present study, we statistically analyzed such data from six inlets of three wastewater treatment plants, covering six regions of Stockholm, Sweden, collected over an approximate year...journal article 2023

Estimation of drone intention using trajectory frequency defined in radar's measurement phase planesYun, Joongsup (author), Anderson, David (author), Fioranelli, F. (author)This paper presents a radar-based algorithm for autonomous estimation of drone intention. The algorithm is based on radar's kinematic measurements, providing fast and robust intention estimation for multiple targets. The core idea of the proposed algorithm is to build intention-specific features for each intention in advance and use them in...journal article 2023

Gabriela Duque, Ana (author), Gonçalves Melo Pequito, S.D. (author), Rosado Coelho, Joana (author)Contribution: We re-think the ‘Statistical Analysis’ curriculum building upon system engineering tools where assumptions (e.g., ABET criteria and student profiles) are carefully assessed, a learn-by-mistake approach ensures that several of the main statistical mistakes are learned, and advanced topics are proposed to make a strong connection...report 2020

Varkey, D. (author), Hicks, M.A. (author), van den Eijnden, A.P. (author), Vardon, P.J. (author)Various simplified approaches are used to calculate the characteristic values of shear strength properties, which have then been used in deterministic stability analyses of a dyke cross-section. The calculated factors of safety are compared with the 5-percentile ‘system response’ of the dyke cross-section, calculated using the more exhaustive...journal article 2020

Kifetew, Fitsum (author), Devroey, Xavier (author), Rueda, Urko (author)We report on the results of the seventh edition of the JUnit tool competition. This year, four tools were executed on a benchmark with (i) new classes, selected from real-world software projects, and (ii) challenging classes from the previous edition. We use Randoop and manual test suites from the projects as baselines. Given the interesting...conference paper 2019

Magalhaes de Medeiros, E. (author), Posada Duque, J.A. (author), Noorman, H.J. (author), Filho, Rubens Maciel (author)Syngas fermentation is one of the bets for the future sustainable biobased economies due to its potential as an intermediate step in the conversion of waste carbon to ethanol fuel and other chemicals. Integrated with gasification and suitable downstream processing, it may constitute an efficient and competitive route for the valorization of...journal article 2019

Liu, K. (author), Vardon, P.J. (author), Hicks, M.A. (author)Internal erosion, or piping, has been attributed as a major cause of dam and embankment failures. Most prediction models for predicting piping use the hydraulic gradient between the upstream and downstream water levels as an indicator. No explicit consideration is made regarding preferential pathways, although piping usually initiates from a...journal article 2019

Khalilnezhad, H. (author), Popov, M. (author), van der Sluis, L. (author), Bos, Jorrit A. (author), Ametani, Akihiro (author)Energization overvoltages are among the severest overvoltages stressing insulations of EHV power system components. Since these overvoltages have a statistical nature, the insulation level should be determined with the use of a statistical approach by which the distribution of overvoltages is calculated. Literature has properly studied the...journal article 2018

(author), Ametani, Akihiro (author)Zero-missing is a phenomenon in shunt compensated cable systems in which the current through the line breaker does not cross the zero point for several cycles. This paper deals with a thorough investigation on countermeasures of the zero-missing phenomenon in transmission systems and determines the requirements, benefits, and risks of...journal article 2018

(author), Dijkstra, J (author)Intravascular optical coherence tomography (IVOCT) is an intravascular imaging modality which enables the visualization arterial structures at the micro-structural level. The interpretations of these structures is mainly on the basis of relative image intensities. However, even for homogeneous tissue light intensities can differ. In this study...conference paper 2016

Wang, B. (author), Hicks, M.A. (author), Vardon, P.J. (author)The random material point method (RMPM), which combines random field theory and the material point method (MPM), is proposed. It differs from the random finite-element method (RFEM), by assigning random field (cell) values to material points that are free to move relative to the computational grid rather than to Gauss points in a conventional...journal article 2016

(author)A design scheme is proposed to evaluate the safety of continuous linear structure i.e. river levee. The scheme is developed to establish a procedure to continuously evaluate the stability failure of embankment during flood runoff by seepage, and to identify locations for reinforcement of river levee. A 20km stretch of a fairly large river...conference paper 2015

Lloret Cabot, M. (author), Hicks, M.A. (author), Van den Eijnden, A.P. (author)Spatial variability of soil properties is inherent in soil deposits, whether as a result of natural geological processes or engineering construction. It is therefore important to account for soil variability in geotechnical design in order to represent more realistically a soil’s in situ state. This variability may be modelled as a random field,...journal article 2012
