Silva Ortiz, P. (author), de Oliveira Junior, Silvio (author), Mariano, Adriano Pinto (author), Jocher, Agnes (author), Posada Duque, J.A. (author)The aeronautical sector faces challenges in meeting its net-zero ambition by 2050. To achieve this target, much effort has been devoted to exploring sustainable aviation fuels (SAF). Accordingly, we evaluated the technical performance of potential SAF production in an integrated first- and second-generation sugarcane biorefinery focusing on...journal article 2024

Cheng, Y. (author), Krishnakumari, P.K. (author)To analyze inherent and diverse patterns within line-based public transport daily delay occurrences, we introduce a data-driven exploratory analysis focused on the spatial-temporal distribution of these delays. Our approach relies on the utilization of the image pattern recognition technique and k-means clustering algorithm. We extract daily...journal article 2024

Ciszewski, M.G. (author), Söhl, J. (author), Jongbloed, G. (author)The past decade has seen an increased interest in human activity recognition based on sensor data. Most often, the sensor data come unannotated, creating the need for fast labelling methods. For assessing the quality of the labelling, an appropriate performance measure has to be chosen. Our main contribution is a novel post-processing method...journal article 2023

Raju, Narayana (author), Arkatkar, Shriniwas (author), Easa, Said (author), Joshi, Gaurang (author)The paper presents the performance analysis of a well-designed truck parking terminal, which is planned for regulating truck traffic over a commercial port. The designed truck parking terminal is modeled using microscopic traffic simulation, which is validated based on the movement of vehicles to the parking bays. After validation, various...journal article 2022

van Oorschot, Kim E. (author), Akkermans, Henk A. (author), Van Wassenhove, Luk N. (author), Wang, Y. (author)Purpose: Due to the complexity of digital services, companies are increasingly forced to offer their services “in permanent beta”, requiring continuous fine-tuning and updating. Complexity makes it extremely difficult to predict when and where the next service disruption will occur. The authors examine what this means for performance measurement...journal article 2022

Lin, X. (author), Nishiki, Yoshinari (author), Tavasszy, Lorant (author)Crowdshipping systems are receiving increasing attention in both industry and academia. Different aspects of crowdshipping (summarized as platform, supply, and demand) are investigated in research. To date, the mutual influence of crowdshipping platform design and its supply side (with participating crowdshippers) has not yet been thoroughly...journal article 2020

Sanchez, Francisco (author), Cayenne, Joshua (author), González-Longatt, Francisco (author), Rueda, José L. (author)The increased adoption of renewable energy generation is reducing the inertial response of the Great Britain (GB) power system, which translates into larger frequency variations in both transient and pseudo-steady-state operation. To help mitigate this, National Grid, the transmission system operator in GB, has designed a control scheme...journal article 2019

Rezaei, J. (author), van Wulfften Palthe, Linde (author), Tavasszy, Lorant (author), Wiegmans, B. (author), van der Laan, Frank (author)Purpose: Port performance and port choice have been treated as separate streams of research. This hampers the efforts of ports to anticipate on and respond to possible future changes in port choice by shippers, freight forwarders and carriers. The purpose of this paper is to develop and demonstrate a port performance measurement methodology,...journal article 2018

Sunil, E. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author), Maas, J.B. (author)In the context of decentralized separation, airspace stability pertains to the propagation of con?ict chain reactions as a result of tactical con?ict resolution maneuvers. This notion of airspace stability has been used in previous literature to develop a semi-empirical method for determining the capacity of a decentralized direct-routing...conference paper 2017

Tra, M.A.P. (author), Sunil, E. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author), Maas, J.B. (author)Previous research relating airspace structure and ca-pacity has shown that a decentralized layered airspace concept, in which each altitude band limited horizontal travel to within a prede?ned heading range, improved safety when compared to unstructured airspace. However, the extent of the safety bene?ts of such layered airspace designs were not...conference paper 2017

Hoekstra, J.M. (author), Maas, J.B. (author), Tra, M.A.P. (author), Sunil, E. (author)In many ATM studies experiments are performed to determine the capacity. This paper looks at the effect of airspace design on the capacity. Using an algebraic approach a relation is derived between the design parameters of a layered airspace design and the capacity of the airspace. The validity of the assumptions which are used in this...conference paper 2016
