Du, Z. (author), van den Berg, J.L. (author), Dimitrovski, T. (author), Litjes, R. (author)Social VR aims at enabling people located at different places to communicate and interact with each other in a natural way. It poses extremely strong throughput and latency requirements on the underlying communication networks. This paper investigates the potential of using cross-layer design approaches for radio access scheduling in order to...conference paper 2023

Nycander, E. (author), Morales-Espana, G. (author), Soder, L. (author)This paper presents power-based unit commitment (UC) formulations with N-1 security constraints. Two different formulations are proposed, one with constant reserves within the hour and one with time-varying reserves. The formulations are compared to a conventional energy-based UC formulation using different examples. We show that the energy...conference paper 2022

(author), Yorke-Smith, N. (author)Logistics planning is a complex optimization problem involving multiple decision makers. Automated scheduling systems offer support to human planners; however state-of-the-art approaches often employ a centralized control paradigm. While these approaches have shown great value, their application is hindered in dynamic settings with no central...conference paper 2022

Phillipson, F. (author), Bontekoe, T.H. (author), Chiscop, I. (author)Energy storage systems and home energy management and control systems will play an important role in reaching the Paris Agreement on climate change. Underlying scheduling mechanisms will lead to a computational burden when the size of the systems and the size of the control space increase. One, upcoming alternative to overcome this computational...conference paper 2021

Gómez, J.F. (author), Shoeibi Omrani, P.S. (author), Belfroid, S.P.C. (author)In gas wells, decreased/unstable production can occur due to difficult-to-predict dynamic effects resulted from late-life phenomena, such as liquid loading and flooding. To minimize the negative impact of these effects, maximize production and extend the wells’ lifetime, wells are often operated in an intermittent production regime. The goal of...conference paper 2021

van de Ven, H. (author), Hulsegge, G. (author), de Korte, E.M. (author), Burdorf, A. (author), Oude Hengel, K.M. (author)Objectives This study aimed to estimate acute effects of roster characteristics on fatigue and sleep quality and investigated whether these effects differed by individual characteristics. Methods Using an ecological measurement assessment survey, fatigue and sleep quality were daily measured among 223 shift workers for up to eight weeks. A...article 2021

Raftopoulou, M. (author), Litjens, R. (author)Network slicing has been introduced in 5G networks as an enabling feature for the effective Quality of Service (QoS) provisioning to multiple service classes with distinct performance requirements. When applied in the Radio Access Network (RAN), a class-specific slice is assigned a set of radio resources and can furthermore be optimally...conference paper 2021

Braam, S. (author), Litjens, R. (author), Smulders, P. (author), Ijntema, W. (author)We present a simulation-based assessment of the performance potential of distributed MIMO (D-MIMO), multi-user MIMO (MU-MIMO) and particularly the combined D/MU-MIMO operation, for which we extend previously published scheduling and beamforming principles. The assessment study reveals that, when optimizing average user throughput performance, D...conference paper 2020

Hussain, I. (author), Awan, M.A. (author), Souto, P.F. (author), Bletsas, K. (author), Akesson, B. (author), Tovar, E. (author)The well-known model of Vestal aims to avoid excessive pessimism in the quantification of the processing requirements of mixed-criticality systems, while still guaranteeing the timeliness of higher-criticality functions. This can bring important savings in system costs, and indirectly help meet size, weight and power constraints. This efficiency...article 2020

Engels, W.P. (author), van der Hoek, D. (author), Yu, W. (author), Reyes Baez, R. (author)Many wind turbines are still controlled using gain scheduled, PI(D) controllers. Another option is to use a state feedback controller, such as LQG control. However, for wind turbines that is not straight forward solution, because the system is non-linear and the impact of pitching on the states varies in time. This paper presents a variation on...conference paper 2020

Oosterman, J.E. (author), Wopereis, S. (author), Kalsbeek, A. (author)Obesity and type 2 diabetes (T2D) have become a global health concern. The prevalence of obesity and T2D is significantly higher in shift workers compared to people working regular hours. An accepted hypothesis is that the increased risk for metabolic health problems arises from aberrantly timed eating behavior, that is, eating out of synchrony...article 2020

Appropriate service function chaining resource allocation is required to comply with the service level required by the application. In this paper, we introduce a dynamic priority assignment for flows that...conference paper 2019

Awan, M.A. (author), Bletsas, K. (author), Souto, P.F. (author), Akesson, B. (author), Tovar, E. (author)In mixed-criticality systems, tasks of different criticality share system resources, mainly to reduce cost. Cost is further reduced by using adaptive mode-based scheduling arrangements, such as Vestal's model, to improve resource efficiency, while guaranteeing schedulability of critical functionality. To simplify safety certification, servers...conference paper 2019
