(author), Theelen, M.A.H. (author), Yilmaz, P. (author), Kettle, J. (author)The degradation of photovoltaic (PV) systems is one of the key factors to address in order to reduce the cost of the electricity produced by increasing the operational lifetime of PV systems. To reduce the degradation, it is imperative to know the degradation and failure phenomena. This review article has been prepared to present an overview of...article 2022

Chai, X. (author), Rozsas, A. (author), Slobbe, A. (author), Teixeira, A. (author)This paper investigates the impact of structural health monitoring (SHM) on the failure probability of a simulated sheet pile wall system. We use Bayesian statistics to estimate non-directly observable soil parameters from measured structural responses. These estimates are used to calculate the failure probability of the structure against...article 2022

Mokkink, L.B. (author), de Vet, H. (author), Diemeer, S. (author), Eekhout, I. (author)Simulation studies were performed to investigate for which conditions of sample size of patients (n) and number of repeated measurements (k) (e.g., raters) the optimal (i.e., balance between precise and efficient) estimations of intraclass correlation coefficients (ICCs) and standard error of measurements (SEMs) can be achieved. Subsequently, we...article 2022

(author)Background: Study participants and patients often perceive (long) questionnaires as burdensome. In addition, paper-based questionnaires are prone to errors such as (unintentionally) skipping questions or filling in a wrong type of answer. Such errors can be prevented with the emergence of mobile questionnaire apps. Objective: This study aimed to...article 2022

Leva, S. (author), Ogliari, E. (author), Ott, M.G.C. (author), Aninat, R. (author), Yilmaz, P. (author)CIGS (CuInGaSe2) solar cells are electronic devices that directly transform sunlight into electricity and fall into the category of thin film photovoltaic devices. Currently, this type of solar cell has reached the record in photovoltaic conversion efficiency of around 23.35%. However, the maturity of a PV technology also requires reliability...conference paper 2022

Terluin, B. (author), Eekhout, I. (author), Terwee, C.B. (author)Objectives: The anchor-based minimal important change (MIC), based on the receiver operating characteristic (ROC) analysis or predictive modeling, is biased by the proportion of improved patients. The adjusted MIC, published in 2017, adjusts the predictive MIC for this bias but does not take the reliability of the transition ratings (i.e., the...article 2022

Sabbadini, A. (author), Massaad, J. (author), van Neer, P.L.M.J. (author), de Jong, N. (author), Verweij, M.D. (author)In recent years, several fitting techniques have been presented to reconstruct the parameters of a plate from its Lamb wave dispersion curves. Published studies show that these techniques can yield high accuracy results and have the potential of reconstructing several parameters at once. The precision with which parameters can be reconstructed...article 2022

Yilmaz, P. (author), Aninat, R. (author), Cruz, G.O. (author), Weber, T. (author), Schmitz, J. (author), Theelen, M. (author)An extensive post-mortem analysis was conducted on a commercial copper-(indiumgallium)-diselenide (CIGS) photovoltaic module that degraded after exposure to the high voltage stress of a standardized potential induced degradation (PID) test. We employed a custom-developed coring technique to extract samples from the full-size field module, which...article 2022

Bakker, K. (author), Sala, J. (author), Najafi, M. (author), Daenen, M. (author), Geerligs, B. (author)During partial shading of a monolithically interconnected cell string, the shaded cells can operate at a reversed voltage. This negative voltage can lead to degradation of the shaded cell. For a successful practical application of large area Perovskite modules (e.g. in four terminal tandems) a shade tolerant top module is required. In this study...conference paper 2022

(author)System voltages can cause significant degradation in photovoltaic modules. Polarization-type potential-induced degradation (PID) is accompanied by decreases in the short-circuit current density and the open-circuit voltage. The system voltage causes a polarization and surface charge accumulation, increasing the interface recombination. The...article 2021

Maljaars, J. (author), Misiek, T. (author)Many steel rope systems are subjected to fluctuating tensile loads and therefore can fail due to fatigue. Available fatigue test data indicate that rope diameter, mean stress, socket type, lay angle and rope length influence the fatigue resistance. Most of the tests were terminated before full failure of the ropes. This paper shows that the test...article 2021

Steenbergen, R.D.J.M. (author)Until recently earthquakes were not taken into account in the Dutch Building Decree and other Dutch building regulations. Although in 1992, an earthquake happened in Roermond with a magnitude of 5.8 on the Richter scale which damaged buildings, this was not seen by the law makers as an argument for the introduction of regulations for earthquake...article 2021
