SUN, Hanchu (author)Surveillance cameras have become increasingly prevalent in public areas worldwide, including in Amsterdam. In Amsterdam, the number and intensity of surveillance cameras in public spaces, such as streets, parks, and plazas, have reportedly increased, even in locations where they were already well-established. In addition to the growing number of...master thesis 2023

(author), Barnett, Heather (author), Scerri, Paul (author)A single sheepdog can bring together and manoeuvre hundreds of sheep from one location to another. Engineers and ecologists are fascinated by this sheepdog herding because of the potential it provides for ‘bio-herding’: a biologically inspired herding of animal groups by robots. Although many herding algorithms have been proposed, most are...journal article 2023

Izquierdo-Lara, Ray W. (author), Heijnen, Leo (author), Oude Munnink, Bas B. (author), Schapendonk, Claudia M.E. (author), Elsinga, Goffe (author), Langeveld, J.G. (author), Post, Johan (author), Prasad, Divyae K. (author), Medema, G.J. (author)Monitoring of SARS-CoV-2 in wastewater (WW) is a promising tool for epidemiological surveillance, correlating not only viral RNA levels with the infection dynamics within the population, but also to viral diversity. However, the complex mixture of viral lineages in WW samples makes tracking of specific variants or lineages circulating in the...journal article 2023

Haifawi, Hani (author)Drone detection and tracking systems are nowadays a requirement in most public, private and political events, because of the increasing risk of unintentional or malicious misuse of these platforms. Moreover, in order to ensure adequate protection, full spatial coverage is a must for every such system. However, the research literature focuses on...master thesis 2022

Maas, J.B. (author)Safety is crucial in aviation. This includes the category of General Aviation, which consists of flights that are not performed by commercial airliners. Many of these vehicles are small in comparison to the aircraft used for commercial transport, providing seats for two or four persons. Despite their limited size, accidents involving General...doctoral thesis 2022

Knuyt, Jerry (author)The loss of wildlife due to illegal poaching activity poses threats on both the survival of iconic animal species and the livelihood of local communities. This research proposes a distributed surveillance model in which a UAV swarm autonomously coordinates continuous surveillance in a dynamic environment. The adaptive behaviour of poachers has...master thesis 2022

van Brakel, Rosamunde (author), Kudina, O. (author), Fonio, Chiara (author), Boersma, Kees (author)This paper focuses on two examples of the introduction and use of COVID-19 contact tracing apps in The Netherlands (CoronaMelder) and Belgium (Coronalert). It aims to offer a critical, sociotechnical perspective on tracing apps to understand how social, technical, and institutional dimensions form the ingredients for increasing surveillance....journal article 2022

Roosenbrand, E.J. (author), Sun, Junzi (author), Dedoussi, I.C. (author), Stam, D.M. (author), Hoekstra, J.M. (author)Sustainability is the biggest challenge facing the aerospace industry today. With the global number of flights expected to rise, the climate impact of aviation will continue to increase. Current research states that the rerouting of aircraft through wind-optimisation for the purpose of fuel usage minimisation and emission reduction is an...conference paper 2022

Danaei, Deniz (author)<br/>The fight against the illegal hunting of African wildlife is a never-ending process. In order to preserve animal habitats and save them from extinction, many national parks utilize surveilling solutions to prevent, detect and locate intruders. One strategy to detect and locate the illegal hunters or so-called \textit{poachers} is to detect...master thesis 2021

van Asten, Timo (author)To create safe urban areas, it is important to gain insight into what influences the (perceived) safety of our cities and human settlements. One of the factors that can contribute to safety is the way urban spaces are designed. Previous work has highlighted the importance of natural surveillance: a type of surveillance that is a byproduct of how...master thesis 2021

Korthals Altes, Maurits (author)The introduction of Robotic & Autonomous Systems (RAS) in modern combat seems inevitable, with clear advantages like reduced risk and extensification of personnel. To scope this research, persistent reconnaissance with heterogeneous Unmanned Aerial Vehicles (UAVs) is selected, being one of the more prominent applications. Despite continuous...master thesis 2021

Hop, Lucas (author)Persistent surveillance is the act of covering an environment persistently, as fast as possible. By exploiting the intelligence of the swarm, it is possible to create a swarm robotic persistent surveillance method that can deal with unknown dynamic environments without the need for complex computations or excessive storage. Using stigmergy,...master thesis 2021

van Nes, A. (author), Yamu, Claudia (author)In this chapter, we discuss and demonstrate how to analyse the urban micro-spatial relationships between private and public spaces. These methods allow one to analyse intervisibility between buildings andstreets, entrance density from buildings towards streets, street constitutedness, and the topological depth between private and public spaces....book chapter 2021

Sun, Junzi (author)<br/><br/>In the last twenty years, aircraft surveillance has moved from controller-based interrogation to automatic broadcast. The Automatic Dependent Surveillance-Broadcast (ADS-B) is one of the most common methods for aircraft to report their state information like identity, position, and speed. Like other Mode S communications, ADS-B makes...book 2021
