Mohammadkarimi, M. (author), Leus, G.J.T. (author), Rajan, R.T. (author)A new method for joint ranging and Phase Offset (PO) estimation of multiple drones/aircrafts is proposed in this paper. The proposed method employs the superimposed uncoordinated Automatic Dependent Surveillance-Broadcast (ADS-B) packets broadcasted by drones/aircrafts for joint range and PO estimation. It jointly estimates range and PO prior...journal article 2024

Noorian Najafabadi, S.A. (author), Ding, Er (author), Hobeika, N. (author), Bluyssen, P.M. (author)Indoor air quality (IAQ) is an important aspect of maintaining human health and well-being, particularly since people spend most of their time indoors. Carpets, with their large surface area and dense fibre piles, have the potential to significantly impact IAQ by emitting and absorbing volatile organic compounds (VOC) from building materials and...journal article 2024

(author)This study reports the effects of microaeration on a laboratory-scale AnMBR (MA-AnMBR) fed with synthetic concentrated domestic sewage. The imposed oxygen load mimics the oxygen load coming from a dissolved air flotation (DAF) unit, establishing an anaerobic digester-DAF (AD-DAF) combination with sludge recycling. Results showed a reduced COD...journal article 2023

Stougie, L. (author), de Raad, B.W. (author), van der Kooi, H.J. (author), Korevaar, G. (author)In view of the energy transition, it is important that engineering students are familiar with the concept of exergy and the added value of exergy analysis compared to energy analysis. Exergy analysis tells the truth about energy efficiency and exergy is directly related to sustainable development. This paper focuses on teaching exergy to...conference paper 2023

Rudra, Koustav (author), Fernando, Zeon Trevor (author), Anand, A. (author)Pre-trained contextual language models such as BERT, GPT, and XLnet work quite well for document retrieval tasks. Such models are fine-tuned based on the query-document/query-passage level relevance labels to capture the ranking signals. However, the documents are longer than the passages and such document ranking models suffer from the token...journal article 2023

Sun, Junzi (author), Tassanbi, A. (author), Obojski, Piotrek (author), Plantholt, Philip (author)The increasing demand for global air travel has intensified the urgency to mitigate aviation’s carbon emissions. Continuous monitoring of aircraft fuel efficiency and emissions has become an important task in aviation. One of the main challenges has been the lack of surveillance data for flights across oceans, specifically in the North Atlantic...conference paper 2023

Marinescu, M. (author), Olivares, Alberto (author), Staffetti, Ernesto (author), Sun, Junzi (author)This paper addresses the problem of spatiotemporal wind velocity field estimation for air traffic management applications. Using data obtained from aircraft, the eastward and northward components of the wind velocity field inside a specific air space are calculated as functions of time. Both short-term wind velocity field forecasting and wind...journal article 2023

Banerjee, I. (author)In a dynamic or disruptive situation, such as disasters, a fully mobile and decentralized infrastructure-less network seems to be a viable option for communication. Citizens are confronted with challenges such as complicated deployment of these networks, resource-constrained mobile phones and mobility. This requires communication networks to...doctoral thesis 2022

YANG, X. (author), Sun, Junzi (author), Rajan, R.T. (author)Automatic Dependent Surveillance - Broadcast (ADS-B) is a surveillance technology that is used extensively in Air Traffic Control (ATC) applications. Aircraft equipped with ADS-B transponders actively broadcast navigation information such as position, altitude, and velocity, and thus ATC is able to track aircraft continuously, even in regions...conference paper 2022

Rijkens, A.A.K. (author), Mikelic, A. (author)The seakeeping behaviour of naval ships is an important factor for its operational effectiveness, as vessels with good seakeeping abilities are able to go to sea and successfully execute their missions despite possible adverse weather conditions. Hence, it is not surprising that the hydrodynamic assessment of a new frigate type hull forms is...journal article 2022

Sun, Junzi (author), Olive, Xavier (author), Strohmeier, Martin (author)Civil aviation contributes to rising global greenhouse gas emissions. Flights carried out by private and business jets are only a very small fraction of commercial passenger flights. However, these private flights are extremely environmentally inefficient and account for the most emissions per passenger in the aviation sector. While the...journal article 2022
