Large wind farm aggregation and model validation
… GE doubly fed induction generator wind turbine modeled in the PowerWorld Simulator. Through this research, we have shown that: • A large wind farm using the GE DFIG wind turbines can be consistently aggregated to one equivalent machine for load flow and transient stability studies. • The low …

Cox-type model validation with recurrent event data
… name a few. It is therefore important to develop models that describe the dynamic evolution of the event occurrences. One major problem of interest to researchers with these types of data is models for the distribution function of the time between events occurrences, especially in the presence of …

Model Validation and Inversion of Active Implantable Medical Devices
The model validation and inversion for active implantable medical devices (AIMD) used for safety evaluations under magnetic resonance imaging (MRI) radio frequency (RF) coil emission were discussed. A mathematical derivation is presented to provide guidance on selecting meaningful pathways for the …

Bayesian-based simulation model validation for spacecraft thermal systems
… of space flight, spacecraft thermal system modeling software has advanced significantly, but the model validation process, in general, has changed very little. Although most thermal systems are successful, there is evidence of some model inaccuracy and thermal system overdesign due to the …

Automated reaction mechanism generation : data collaboration, Heteroatom implementation, and model validation
… to global warming. This is not a sustainable model. The United States government has recently passed legislation that requires greenhouse gas emissions to be reduced to 80% of the 2005 level by the year 2050. Furthermore, new legislation under the Energy Independence and Security Act (EISA) …

Control Design and Model Validation for Applications in Nonlinear Vessel Dynamics
In recent decades, computational models have become critical to how engineers and mathematicians understand nature; as a result they have become an integral part of the design process in most engineering disciplines. Moore's law anticipates computing power doubling every two years; a prediction …

Key challenges to model-based design : distinguishing model confidence from model validation
Model-based design is becoming more prevalent in industry due to increasing complexities in technology while schedules shorten and budgets tighten. Model-based design is a means to substantiate good design under these circumstances. Despite this, organizations often have a lack of confidence in the …

A multi-sensor approach to the retrieval and model validation of global cloudiness
… a daunting challenge to the atmospheric modeling community from the very beginning. Namely, their far-reaching importance to the energy balance and hydrological cycle of our planet is eclipsed only by the level of complexity at which they are nested within the non-linear climate feedback …

Assessment of Model Validation, Calibration, and Prediction Approaches in the Presence of Uncertainty
Model validation is the process of determining the degree to which a model is an accurate representation of the true value in the real world. The results of a model validation study can be used to either quantify the model form uncertainty or to improve/calibrate the model. However, the model …

Finite Element Model Validation and Testing of an Off-Road Vehicle under Dynamic Loading Conditions
<p>In the vehicle design life cycle, validation tests consume a significant portion of the available development time. With a short, one-year design cycle, the Embry-Riddle Baja Team leverages computer-aided engineering (CAE) tools to simulate critical test cases whose loading conditions can be …
