State maps for linear systems
No full textModeling of physical systems consists of writing the equations describing a phenomenon and yields as a result a set of differential-algebraic equations. As such, state-space models are not a natural starting point for modeling, while they have utmost importance in the simulation and control phase. The paper addresses the problem of computing state variables for systems of linear differential-algebraic equations of various forms. The point of view from which the problem is considered is the behavioral one, as put forward in [J. C. Willems, Automatica J. IFAC, 22 (1986), pp. 561–580; DynamicsReported,2(1989),pp.171–269;IEEETrans.Automat.Control,36(1991),pp. 259–294]

Validating dental age estimation in Kenyan black children and adolescents using the Willems method
No full textPURPOSE: This study aimed to validate the Willems Belgian Caucasian (Willems BC) age estimation model in a Kenyan sample, to develop and validate a Kenyan-specific (Willems KB) age estimation model and to compare the age prediction performances of both models. METHODS: Panoramic radiographs of 1038 (523 female, 515 male) Kenyan children without missing permanent teeth and without all permanent teeth fully developed (except third molars) were retrospectively selected. Tooth development of the seven lower-left permanent teeth was staged according to Demirjian et al. The Willems BC model, performed on a Belgian Caucasian sample and a constructed Kenyan-specific model (Willems KB) were validated on the Kenyan sample. Their age prediction performances were quantified and compared using the mean error (ME), mean absolute error (MAE) and root-mean-square error (RMSE). RESULTS: The ME with Willems BC method equalled zero. Hence, there was no systematic under- or overestimation of the age. For males and females separately, the ME with Willems BC was significantly different from zero, but negligible in magnitude (-0.04 and 0.04, respectively). Willems KB was found not to outperform Willems BC, since the MAE and RMSE were comparable (0.98 vs 0.97 and 1.31 vs 1.29, respectively). Although Willems BC resulted in a higher percentage of subjects with predicted age within a one-year difference of the true age (63.3% vs 60.4%, p=0.018), this cannot be considered as clinically relevant. CONCLUSION: There is no reason to use a country-specific (Willems KB) model in children from Kenya instead of the original Willems (BC) model.status: Publishe

In this interview, Pieter Willems, senior pastor of Mustard Seed Church in Lawrence, Kansas, describes the history and development of Mustard Seed Church, from its Jesus Movement origins in downtown Lawrence to growing into the church that it is today, now based in West Lawrence. He also discusses how the church functions logistically and programmatically, and describes his vision and heart for the church.

The academic career of the caterpillar track. Means of progression - Meaning of progress.
No full textDiscussing the forms of research that are relevant in higher art education, we can metaphorically use various means of progression. In that respect, the caterpillar track in particular stands out for Bert Willems. How can the caterpillar track provide insights into the way we look at and think about progress? We end up with the suggestion that the art school is a good environment for artistic researchers as happy, critical, but nonetheless intrusive explorers of reality
