Kingma, B.R.M. (author), Sullivan-Kwantes, W. (author), Castellani, J.W. (author), Friedl, K.E. (author), Haman, F. (author)This paper defines functional cold exposure zones that illustrate whether a person is at risk of developing physical performance loss or cold weather injuries. Individual variation in body characteristics, activity level, clothing and protective equipment all contribute to variation in the effective exposure. Nevertheless, with the right...article 2023

(author)Inventory estimates of N2O and CH4 emissions disregard temporal and spatial variabilities, which hinders the search for effective local strategies to lower greenhouse gas emissions. We have quantified the emissions of N2O and CH4 in a mixed agriculture-urban region using two independent approaches, i.e., the vertical gradient method (VGM) and...article 2023

Santos, R.D. (author), Aguilar, J. (author), Rodriguez-Moreno, M.D. (author)In a smart environment like the smart grids, it is necessary to have knowledge models that allow solving emerging problems. However, large datasets are required to automatically create these models, which in the vast majority of cases are not available. Therefore, in these environments is essential to have a data generator for each context. In...conference paper 2022

Oosterman, D.T. (author), Langenkamp, W.H. (author), van Bergen, E.L. (author)In this paper we describe our initial findings on a method for improving anomaly detection on a dataset with scarcely labeled data, based on an ongoing use-case with the Belgian Customs Administration (BCA). Data on shipping containers is used to predict the level of risk associated with a shipment, as well as the probability that the shipment...conference paper 2022

Li, L. (author), Hoefsloot, H. (author), de Graaf, A.A. (author), Acar, E. (author), Smilde, A.K. (author)Background: Analysis of dynamic metabolomics data holds the promise to improve our understanding of underlying mechanisms in metabolism. For example, it may detect changes in metabolism due to the onset of a disease. Dynamic or time-resolved metabolomics data can be arranged as a three-way array with entries organized according to a subjects...article 2022

Phillipson, F. (author), Wezeman, R.S. (author), Chiscop, I. (author)Communication networks are managed more and more by using artificial intelligence. Anomaly detection, network monitoring and user behaviour are areas where machine learning offers advantages over more traditional methods. However, computer power is increasingly becoming a limiting factor in machine learning tasks. The rise of quantum computers...article 2021

Both compensation methods are implemented using a small pixel circuit, namely, a 3T2C and a 2T1C pixel circuit, allowing high-resolution displays. Due to the simple driving schemes, these...article 2021

(author), Dehaene, W. (author), Myny, K. (author)This paper presents a new compensation principle using a 2T1C pixel circuit. The implementation shows significant improvement in uniformity for all grey-levels, due to compensation for both VT and β-factor variations. The resulting current variation after compensation in the characterized display area reaches values down to 0.079%.conference paper 2020

Klusener, S. (author), Mooij, A.J. (author), Ketema, J. (author), van Wezep, H. (author)When software components are developed iteratively, code frequently evolves in an inductive manner: A unit is created and is then copied and modified many times. Such development often happens when variation points and, hence, proper domain abstractions are initially unclear. As a result, there may be substantial amounts of code duplication, and...conference paper 2018

Mohammadi, M. (author), Tan, Y.H. (author), Hofman, W. (author), Mousavi, S.H. (author)The l1-regularized least square problem has been considered in diverse fields. However, finding its solution is exacting as its objective function is not differentiable. In this paper, we propose a new one-layer neural network to find the optimal solution of the l1-regularized least squares problem. To solve the problem, we first convert it into...article 2018
