Predicting the probability of the occurrence of a binary outcome or condition is important in biomedical research. While assessing discrimination is an essential issue in developing and validating binary prediction models, less attention has been paid to methods for assessing model calibration. Calibration refers to the degree of agreement between observed and predicted probabilities and is oft...
Building model calibration is critical in bringing simulated energy use closer to the actual consumption. This paper presents a novel, automated model calibration approach that uses logic linking parameter tuning with bias pattern recognition to overcome some of the disadvantages associated with traditional calibration processes. The pattern-based process contains four key steps: (1) running th...
Modern engines have an increasing number of control parameters that are having a dramatic impact on calibration time. Up-front prototyping of calibration processes can be used to reduce the burden of increasing powertrain complexity, however, such techniques are still in their infancy in the automotive field. In this paper we illustrate how flexible model-based calibration tools can be used to ...
nowadays, due to increasing the complexity of ic engines, calibration task becomes more severe and the need to use surrogate models for investigating of the engine behavior arises. accordingly, many black box modeling approaches have been used in this context among which network based models are of the most powerful approaches thanks to their flexible structures. in this paper four network base...
In a watershed, land use As one of the most effective factors in basin hydrologic response, Can have significant role in the hydrological cycle and water resources. The knowledge of the effects of land use change on basin hydrology responses can help to determine the appropriate strategy to achieve sustainable development of water resources and a management model. The purpose of this study is t...
Extrinsic sensor calibration is an important task in robotics. There are various ways to perform the calibration task, but it often remains unclear which methods are better than the others. In this paper, we provide a systematic study about the calibration accuracy of three types of calibration methods, each represented by an abstract geometric model based on the sensor configuration and the ca...
In this study, the process-based watershed model, Soil and Water Assessment Tool (SWAT), was used for simulating hydrology and sediment transport in the Gharesou watershed and for identifying critical areas of soil erosion and water pollution. After model calibration and uncertainty analysis using SUFI-2 (Sequential Uncertainty Fitting, ver. 2) method, the outputs of the calibrated model were u...
Surface runoff is one of the main causes of erosion and loss of soil fertility, sedimentation in reservoirs and reduction of river water quality. Therefore, the accurate prediction of basin response to precipitation events is very important. Hydrological models are simplified views of the actual watershed systems that can help study watershed functions in response to various inputs, and underst...
Computer simulation models are increasingly popular for predicting soil loss to quantify the processes of detachment, transport and deposition of eroded soils. To assess the effects of different management on soil erosion, selecting the best models and their validation a positive step is considered. In this research the Rangeland Hydrology and Erosion Model (RHEM) was evaluated by using soil er...
