This review paper presents an overview of studies of Potential Induced Degradation (PID) in copper indium gallium diselenide (CIGS) photovoltaics. It reviews the observations reported in literature, the proposed origins of this high voltage-difference-driven degradation effect and the applied testing methods. Studies on cell, minimodule and...

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...

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...

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...

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...

The ever-increasing instalment capacity of Cu (In, Ga)(Se, S)2-based photovoltaicscalls for a better understanding and control of their reliability. In this paper, we showhow using a coring-based method, small samples can be extracted from full size com-mercial modules, and prepared for lab-scale analysis. The method is applied to a Cu(In, Ga)...

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...

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...

This work puts Computational Intelligence in Reliability Engineering in perspective within the larger framework of digitalization and business. The approach is to consider RECI solutions as business solutions in a wider enterprise architecture environment. Using that as a starting point four key components are discussed for successful...

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...

Probabilistic fatigue life prediction models of welded steel joints are often used to estimate the level of safety, which is given in terms of the probability of failure or the reliability index as a function of the applied load cycles. Prediction models based on fracture mechanics allow taking into account the effect of inspections on the...

Bolted connections are applied in many aluminium structures. Stainless steel bolts are often preferred over carbon steel bolts in aluminium connections to prevent galvanic corrosion. However, current design standards and guidelines do not allow for using preloaded stainless steel bolts in slip resistant connections, mainly because of a lack of...

Quantitative Risk Analysis (QRA) is a standard tool in some high-risk industries (such as the on- and offshore exploration and production and chemical industry). Presently, existing knowledge concerning human error likelihood and human reliability assessment is insufficiently represented in QRAs. In this paper we attempt to implement the...

General frameworks for reliability differentiation have evolved over time and are mainly developed for buildings. However, recommendations for the safety of existing quay walls are lacking. In this study, target reliability indices for assessing existing quay walls were derived by economic optimisation and by evaluating the requirements...

This present paper concerns the application of probabilistic fatigue life prediction models based on S–N curves aiming at the estimation of the safety level for a nonload carrying cruciform joint. The safety level is expressed in terms of the reliability index as a function of the number of applied cycles. Estimating the reliability of a...

The assessment of service-proven quay walls subject to corrosion-induced degradation is inherently a time-dependent reliability problem. Two major challenges are the modelling of corrosion and taking into account the decrease of epistemic uncertainty throughout the quay wall’s service life. The main objective of this study is to examine the...
