Evaluating Aviation Emission Inefficiencies and Reduction Challenges with Electric Flights

Sun, Junzi (author), Olive, Xavier (author), Delahaye, Daniel (author)

Inefficiencies in flight operations, like deviations and non-optimal flight speed or altitude, are directly linked to flight emission inefficiencies. Quantifying these emission inefficiencies and studying potential mitigation strategies is certainly beneficial for the sustainability of the aviation industry. In this paper, we analyze emission...

Operational data-driven energy performance assessment of ships: the case study of a naval vessel with hybrid propulsion

Vasilikis, N. (author), Geertsma, R.D. (author), Visser, K. (author)

Ship designers hardly ever receive feedback from the actual operation of their designs apart from sea acceptance trials. Similarly, crews operating the vessels do not receive a clear picture of the energy performance and environmental footprint of different options. This paper proposes a methodology based on operational data from continuous...

What do they know? Investigating students’ ability to analyse experimental data in secondary physics education

Pols, C.F.J. (author), Dekkers, P.J.J.M. (author), de Vries, M.J. (author)

This paper explores students’ ability to analyse and interpret empirical data as inadequate data analysis skills and understandings may contribute to the renowned disappointing outcomes of practical work in secondary school physics. Selected competences, derived from a collection of leading curricula, are explored through interviews and...

AutoStepfinder: A fast and automated step detection method for single-molecule analysis

Loeff, L. (author), Kerssemakers, J.W.J. (author), Joo, C. (author), Dekker, C. (author)

Single-molecule techniques allow the visualization of the molecular dynamics of nucleic acids and proteins with high spatiotemporal resolution. Valuable kinetic information of biomolecules can be obtained when the discrete states within single-molecule time trajectories are determined. Here, we present a fast, automated, and bias-free step...

Detecting and Measuring Turbulence from Mode S Surveillance Downlink Data

Olive, Xavier (author), Sun, Junzi (author)

Instability in the movement of air masses in the atmosphere can result in turbulence. Most often, turbulence causes discomfort to passengers but it can occasionally affect their safety as well. Turbulence experienced by aircraft can be difficult to predict, especially for clear air turbulence (CAT) which occurs in the absence of any visual clues...

Evaluating the impact of new aircraft separation minima on available airspace capacity and arrival time delay

Itoh, E (author), Mitici, M.A. (author)

Although the application of new, reduced aircraft separation minima can directly increase runway throughput, the impact thereof on the traffic flow of aircraft arriving at the destination airport has not been discussed yet. This paper proposes a data-driven and queue-based modeling approach and presents an analysis of the impact on the delay...

Queue-Based Modeling of the Aircraft Arrival Process at a Single Airport

Itoh, Eri (author), Mitici, M.A. (author)

This paper proposes data-driven queuing models and solutions to reduce arrival time delays originating from aircraft arrival processing bottlenecks at Tokyo International Airport. A data-driven analysis was conducted using two years of radar tracks and flight plans from 2016 and 2017. This analysis helps not only to understand the bottlenecks...

Unsupervised machine learning for exploratory data analysis in imaging mass spectrometry

Verbeeck, N. (author), Caprioli, Richard M. (author), Van de Plas, Raf (author)

Imaging mass spectrometry (IMS) is a rapidly advancing molecular imaging modality that can map the spatial distribution of molecules with high chemical specificity. IMS does not require prior tagging of molecular targets and is able to measure a large number of ions concurrently in a single experiment. While this makes it particularly suited...

Reconstructing Aircraft Turn Manoeuvres for Trajectory Analyses Using ADS-B Data

Sun, Junzi (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)

The Automatic Dependent Surveillance-Broadcast (ADS-B) data has become one of the most popular sources of data for trajectory-based ATM studies. It is can be received in most of the world without restrictions. Extended coverage can be achieved with a network of low-cost receivers and satellites. However, the fact that ADS-B is designed to...

The Role of Hosting Providers in Web Security: Understanding and Improving Security Incentives and Performance via Analysis of Large-scale Incident Data

Tajalizadehkhoob, S. (author)

In theory, hosting providers can play an important role in fighting cybercrime and misuse. This is because many online threats, be they high-profile or mundane, use online storage infrastructure maintained by hosting providers at the core of their criminal operations. <br/>However, in practice, we see large differences in the security measures...

Vessel classification method based on vessel behavior in the port of Rotterdam

Zhou, Y. (author), Daamen, W. (author), Vellinga, T. (author), Hoogendoorn, S.P. (author)

AIS (Automatic Identification System) data have proven to be a valuable source to investigate vessel behavior. The analysis of AIS data provides a possibility to recognize vessel behavior patterns in a waterway area. Furthermore, AIS data can be used to classify vessel behavior into several categories. The analysis results would help the port...
