Ranjha, Sayra (author)The temporal correctness of safety-critical systems is typically guaranteed via a response-time analysis, whose goal is to determine the worst-case response time (WCRT) of a set of input jobs when they are scheduled by a given scheduling policy on a computing resource. <br/>However, response-time analysis is a hard problem to solve, with most...master thesis 2021

Zhang, Remy (author), Becoy, Alexander James (author)This thesis focuses on improving the readout of the ADome by implementing MCUs at each antenna probe, enabling local sampling and memory storage. The serial communication protocols CAN, SPI and I2C are considered and compared with one another. Ultimately, CAN is decided due to its robustness and simplicity which make the system cheap and ensures...bachelor thesis 2021

Kamat, Ameya (author), Abbas, Yawar (author), Blagojević, Andrija (author), van Casteren, Toine (author), Walraven, Joost (author)Service life of concrete infrastructure is severely compromised because of chloride-induced corrosion and measuring the chloride content is crucial to determine the remaining service life. DuraCrete provides a chloride ingress model based on Fick’s 2nd law. Although the diffusion coefficient is modelled as a time-dependent variable, the...conference paper 2021

van Giessen, Femke (author)Intersections are the bottleneck of traffic flow. Vehicle-actuated control improved the delay at an intersection by making the green phase variable based on the presence of vehicles as measured by detector loops. The duration of the yellow and red phase remains fixed times because intentions of specific human-driven vehicles (HDVs) are unknown,...master thesis 2021

Creating 3d indoor first responder situation awareness in real-time through a head-mounted ar deviceSmit, Bart Peter (author), Voûte, R.L. (author), Verbree, E. (author)Emergency operations are a key example for the need of digital twins in the way it is complex, urgent and uncertain. First, the process is complex, as many organizations are involved. Second, it is urgent, as most damage is done in the first moments of an emergency. Third, it is uncertain, as situational conditions tend to change quickly. For...journal article 2021

Drabicki, Arkadiusz (author), Cats, O. (author), Kucharski, R.M. (author)Bus bunching is a well-known problem in public transport networks. It is characterized by a self-amplifying relationship between uneven distribution of rising passenger loads and deteriorating service regularity. The focus of this study is to analyse whether this negative feedback loop can be addressed by providing real-time crowding...conference paper 2021

Zhang, Qingzhou (author), Zheng, Feifei (author), Jia, Yueyi (author), Savic, Dragan (author), Kapelan, Z. (author)Real-time hydraulic modelling can be used to address a wide range of issues in a foul sewer system and hence can help improve its daily operation and maintenance. However, the current bottleneck within real-time FSS modelling is the lack of spatio-temporal inflow data. To address the problem, this paper proposes a new method to develop real...journal article 2021

Vermeer, Jop (author), Scandolo, L. (author), Eisemann, E. (author)Ambient occlusion (AO) is a popular rendering technique that enhances depth perception and realism by darkening locations that are less exposed to ambient light (e.g., corners and creases). In real-time applications, screen-space variants, relying on the depth buffer, are used due to their high performance and good visual quality. However, these...journal article 2021
