Vasan Ashok, Vijay (author), Chandra Mouli, G.R. (author), van der Burgt, Jos (author), Peýate Vera, Santiago (author), Huibers, Martijn (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)EV Charging is expected to be a significant load on the grid in the future. But they can also be a part of the solution to grid violations. As the amount of renewable energy generation increases, there is a large amount of power flowing in the reverse direction in the distribution network, which is undesirable. To reduce this, EVs can charge at...conference paper 2016

Jacobs, B. (author), van Driel, W.D. (author), Schuld, M. (author)Commercial claims for LED-based products in terms of lumen maintenance are fully based on TM-21 extrapolations using LM-80 data. We presented an approach based on statistical data analytics, following the work from Yu & Tseng, at EuroSimE2015. Since then, more LM80 test data came available both for High Power (HP) and Mid Power (MP) LEDs....conference paper 2018

(author)We have seen an increasing number of reported colour maintenance issues in the market when it concerns LED-based products. Besides this, there are also requests to provide products that have < 2 SDCM colour point changes over lifetime. To understand the mechanisms behind colour maintenance in our LED-portfolio we have developed a...conference paper 2018

(author)The mechanical part of inertial sensors can be designed to have a large mechanical sensitivity, but also requires the transduction mechanism which translates this displacement. The overall system resolution in mechanical inertial sensors is dictated by the noise contribution of each stage and the magnitude of each sensitivity, see also Figure...conference paper 2018

Fiedler, Davide (author), Čertický, Michal (author), Alonso-Mora, J. (author), Cáp, M. (author)In densely populated-cities, the use of private cars for personal transportation is unsustainable, due to high parking and road capacity requirements. The mobility-on-demand systems have been proposed as an alternative to a private car. Such systems consist of a fleet of vehicles that the user of the system can hail for one-way point-to-point...conference paper 2018

Baldi, S. (author), Kosmatopoulos, Elias B. (author), Pitsillides, Andreas (author), Lestas, Marios (author), Ioannou, Petros A. (author), Wan, Y. (author)An adaptive decentralized strategy for active queue management of TCP flows over communication networks is presented. The proposed strategy solves locally, at each link, an optimal control problem, minimizing a cost composed of residual capacity and buffer queue size. The solution of the optimal control problem exploits an adaptive...conference paper 2016

Satyavada, H. (author), Babuska, R. (author), Baldi, S. (author)The field of energy efficiency in buildings offers challenging opportunities from a control point of view. Heating, Ventilation and Air-Conditioning (HVAC) units in buildings must be accurately controlled so as to ensure the occupants' comfort and reduced energy consumption. While the existing HVAC models consist of only one or a few HVAC...conference paper 2016

Le, Q.T. (author), van den Boom, A.J.J. (author), Baldi, S. (author)This paper investigates the identification of continuous piecewise affine systems in state space form with jointly unknown partition and subsystem matrices. The partition of the system is generated by the so-called centers. By representing continuous piecewise affine systems in the max-form and using a recursive Gauss-Newton algorithm for a...conference paper 2016

Rout, S. (author), Serdijn, W.A. (author)Achieving an accurate sub-Hz high-pass (HP) cutoff frequency and simultaneously a high accuracy of the transfer function is a challenge in the implementation of analog-to-digital converters for biomedical ExG signals. A structured electronic design approach based on state-space forms is proposed to develop HPΣΔ modulators targeting high accuracy...conference paper 2017

Wang, T. (author)The therapeutic properties of light have been known for thousands of years, but photodynamic therapy (PDT) was only developed in the last century. Currently, PDT is in clinical trials for the oncology-the treatment of head and neck, brain, lung, pancreas, abdominal cavity, breast, prostate, and skin cancer. Advantages of the light-based...doctoral thesis 2022
