Hallie, Aileen (author)Light can be a wonderful thing. It allows one to see in the dark. Since the development of lamps, the intention has been to eliminate darkness from the night, as darkness is associated with danger, demons, the unknown, and all sorts of ‘scary’ things that lurk in the dark. Although light is helpful, dark nights are also needed. Not only did...master thesis 2023

(author), Cazaux, S.M. (author)Context. Gas phase Elemental abundances in molecular CloudS (GEMS) is an IRAM 30-m Large Program aimed at determining the elemental abundances of carbon (C), oxygen (O), nitrogen (N), and sulfur (S) in a selected set of prototypical star-forming filaments. In particular, the elemental abundance of S remains uncertain by several orders of...journal article 2023

(author), van Eijck, L. (author)The ANET project aims at developing 2D compact neutron collimators for neutron imaging applications. The results of the ANET collimator performances, presented in this communication, are based on data collected at the FISH beamline at TU-Delft. Two independent methods to evaluate the neutron radiography resolution are described and discussed,...journal article 2023

van Oorschot, Marijn (author)Spacecraft navigation and control is difficult in deep space operations. Especially around asteroids, the irregular gravity field increases the difficulty of estimating the spacecraft trajectory. Autonomous navigation can increase the safety and accuracy for orbit proximity operations. Furthermore, it eliminates the need for continuous...master thesis 2022

Sfikas, Konstantinos (author)On May 22, 2018, the Gravity Recovery and Climate Experiment Follow On (GRACE-FO) mission was launched with the goal to map the spatiotemporal variations in the Earth's gravity field and to extend the 15-year monthly mass change observations of its predecessor, the GRACE mission. Similarly to GRACE, the measurement principle of GRACE-FO is based...master thesis 2022

Junge, Kai (author), Obayashi, Nana (author), Stella, F. (author), Della Santina, C. (author), Hughes, Josie (author)Biology provides many examples of how body adaption can be used to achieve a change in functionality. The feather star, an underwater crinoid that uses feather arms to locomote and feed, is one such system; it releases its arms to distract prey and vary its maneuverability to help escape predators. Using this crinoid as inspiration, we develop a...journal article 2022

He, Zhibo (author), Liu, Chenguang (author), Chu, Xiumin (author), Negenborn, R.R. (author), Wu, Qing (author)For the complex multi-ship encounter scenarios, this article proposes a dynamic collision avoidance path planning algorithm based on the A-star algorithm and ship navigation rules, namely Dynamic Anti-collision A-star (DAA-star) algorithm. A dynamic search mechanism of the DAA-star algorithm considering time factors is designed to enable the...journal article 2022

(author)Dusty star-forming galaxies (DSFGs) at redshift z ≥ 1 are among the most vigorously star-forming galaxies in the Universe. However, their dense (≥10 <sup>5</sup>cm <sup>-3</sup>) gas phase - typically traced by HCN(1-0) - remains almost entirely unexplored: only two DSFGs have been detected in HCN(1-0) to date. We present the results of a...journal article 2022

(author), Paragi, Zsolt (author), Yang, Aiyuan (author), Yang, Xiaolong (author), Shen, Zhiqiang (author)In the time domain, the radio sky in particular along the Galactic plane direction may vary significantly because of various energetic activities associated with stars, stellar, and supermassive black holes. Multi-epoch Very Large Array surveys of the Galactic plane at 5.0 GHz enabled the finding of a catalogue of 39 variable radio sources in...journal article 2022

Yu, G. (author)Creating a gas-liquid foam means dispersing gas as individual bubbles in an aqueous solution, in which each gas bubble is separated by liquid films or lamella. The most common form of liquid foam (as opposed to solid foams, like polymer sponges) seen in day-to-day life is bulk foam. This refers to a foam that rests in a large container (or flows...doctoral thesis 2021

Hussain, Mohammed Muaaz (author)The advent of global warming has brought an increased interest in non-conventional sources of energy, one of which is nuclear energy. Threatening the almost year-round functioning of nuclear power plants are Flow-Induced Vibrations (FIV). One such mechanism, Vortex-Induced Vibration (VIV), holds importance in areas of cross flow in nuclear power...master thesis 2021

de Bruin, Ivar (author)This paper extends the Multi-Agent Pathfinding (MAPF) algorithm, A*+ID+OD, to be able to solve problems with matching. This extension still keeps the optimal and completeness properties of the original algorithm. Matching is added to the algorithm in both an exhaustive and heuristic manner. Exhaustive matching is further improved by adding a new...bachelor thesis 2021

de Jong, Jaap (author)For the Multi-Agent Pathfinding (MAPF) problem, a set of non-colliding paths must be found for multiple agents. In Multi-Agent Pathfinding with Matching (MAPFM), this problem is extended: agents and goals are added to a team and each agent has to navigate to a goal that belongs to the same team. In this paper, two extensions of the EPEA* MAPF...bachelor thesis 2021

Alaily-Mattar, N.M. (author), Akhavan, M. (author), Hein, C.M. (author)A recurrent claim associated with the development of star architecture buildings along new urban waterfronts is that star architecture’s capacity to garner media exposure can support a port city’s efforts to communicate narratives that support the process of urban transformation. However, despite the centrality of the role of the media, little...journal article 2021

During the past 20 years the detection of exoplanets, orbiting stars beyond our own, has moved from science fiction to science fact. From the first handful of gas giants, found...journal article 2021

The addition of waypoints to this problem (MAPFW) gives rise to the possibility of more complex applications, such as in vehicle routing, aviation, computer games or robotics. Yet no algorithms have...bachelor thesis 2020
