MEMS-based Tunable Metasurface for Reflective Display Applications
In an era where portable electronic devices are indispensable for a wide range of activities, the need for displays that provide both long-lasting battery life and excellent visibility in different lighting conditions is increasingly important. Emissive di ...
EPFL2024Lessons Learned from Data-Driven Building Control Experiments: Contrasting Gaussian Process-based MPC, Bilevel DeePC, and Deep Reinforcement Learning
Colin Neil Jones, Yingzhao Lian, Loris Di Natale, Jicheng Shi, Emilio Maddalena
This manuscript offers the perspective of experimentalists on a number of modern data-driven techniques: model predictive control relying on Gaussian processes, adaptive data-driven control based on behavioral theory, and deep reinforcement learning. These ...
2023Variation in Phototopic and Melanopic Lighting in Swiss Offices: A Field Study
Marilyne Andersen, Jan Wienold, Caroline Karmann, Megan Nicole Danell, Clotilde Marie A Pierson
Health requirements for lighting in buildings are becoming increasingly important in building standards. Yet, there is a lack of concrete data on the lighting conditions that prevail in our workplaces, in terms of their spectral characteristics, their seas ...
2023Dynamic pulse scheduling in ASDEX Upgrade: Disruption avoidance and investigation of the H-Mode density limit
Alessandro Pau, Federico Alberto Alfredo Felici, Bernhard Sieglin
Operation of a tokamak device requires the coordinated operation of a multitude of systems. The sequence of operations during a discharge is both too complex and fast for human interaction. A common way of operation is a predefined sequence of operations w ...
ELSEVIER SCIENCE SA2023Comparison of questionnaire items for discomfort glare studies in daylit spaces
Marilyne Andersen, Jan Wienold, Caroline Karmann, Sneha Jain, Geraldine Cai Ting Quek, Clotilde Marie A Pierson
When studying discomfort glare, researchers tend to rely on a single questionnaire item to obtain user evaluations. It is unclear whether the choice of questionnaire item affects the distribution of user responses and leads to inconsistencies between studi ...
2023Validation of spectral simulation tools in the context of ipRGC-influenced light responses of building occupants
Marilyne Andersen, Clotilde Marie A Pierson
With the growing awareness about ipRGC-influenced light (IIL) responses, design applications related to these responses are flourishing. To compare design options and optimize lighting conditions for building occupants, lighting simulations are typically u ...
TAYLOR & FRANCIS LTD2022Visual comfort without borders: Extending daylight glare prediction to dim daylit environments
Avoiding discomfort glare is one of the critical aspects of maintaining visual comfort, which significantly influences occupants' overall satisfaction with their indoor environment. Discomfort glare prediction models have been developed for various lightin ...
EPFL2022Optimized office lighting advances melatonin phase and peripheral heat loss prior bedtime
Jean-Louis Scartezzini, Mirjam Münch, Marta Benedetti, Lenka Maierova
Improving indoor lighting conditions at the workplace has the potential to support proper circadian entrainment of hormonal rhythms, sleep, and well-being. We tested the effects of optimized dynamic daylight and electric lighting on circadian phase of mela ...
2022A simulation tool for building and lighting design considering ipRGC-influenced light responses
Marilyne Andersen, Clotilde Marie A Pierson, Myrta Gkaintatzi-Masouti
The ipRGCs in the human eye mediate several effects on people, such as alertness and circadian rhythms. The spectral, temporal and spatial characteristics of light influence the magnitude of these effects. To facilitate the anticipation of the ipRGC-influe ...
2022High-Efficiency Deep-Red Light-Emitting Electrochemical Cell Based on a Trinuclear Ruthenium(II)-Silver(I) Complex
Turn-on time is a key factor for lighting devices to be of practical application. To decrease the turn-on time value of a deep-red light-emitting electrochemical cells (DR-LECs), two novel approaches based on molecularly engineered ruthenium phenanthroimid ...
