Prediction of Annual Daylighting Performance Using Inverse Models

چکیده

This paper presents the results of a study that developed improved inverse models to accurately predict annual daylighting performance (sDA and lighting energy use) various window configurations. model is an improvement over previous because it can be applied variable room geometries at different weather locations in US. The varied from 3 m × 2.5 15 10 (length width height). other variables used include orientation (N, E, S, W), window-to-floor ratio, location exterior wall, glazing visible transmittance, ceiling reflectance, wall shade type (overhangs, fins), power density (LPD) (W/m2), dimming setpoint (lux). Such quickly advise architects during preliminary design phase about which options provide useful daylighting, while minimizing auxiliary use. tested were multi-linear regression (MLR) models, trained against Radiance-based simulation results. In analysis, 482 cases with conditions simulated, develop validate models. 75% data train 25% model. showed new had high accuracy predictions, R2 0.99 CV(RMSE) 15.19% (RMSE 58.91) for (LE) prediction, 0.95 14.38% 8.02) sDA prediction. addition, validation LE MLR 0.96 0.85, RASE 121.89 8.54, respectively, indicate could

Performance Prediction in Cycling Using Antagonistic Models

Two antagonistic models are used to model the training-performance relationship during an eight week cycling training, with a prediction of the performances in the last week of training. Results indicated different qualities of the model fits for the test data for both models. Mean differences between predicted and real performances were 2.39% for the Fitness-Fatigue-Model and 4.43% for the Per...

Prediction Models for Annual U.S. Hurricane Counts

The authors build on their efforts to understand and predict coastal hurricane activity by developing statistical seasonal forecast models that can be used operationally. The modeling strategy uses May–June averaged values representing the North Atlantic Oscillation (NAO), the Southern Oscillation index (SOI), and the Atlantic multidecadal oscillation to predict the probabilities of observing U...

Prediction of Vapor-Liquid Equilibria Using CEOS /GE Models

The present study investigates the use of different GE mixing rules in cubic equations of state for prediction of phase behavior of multicomponent hydrocarbon systems. To predict VLE data in multicomponent symmetric and asymmetric mixtures such as systems that contain light gases (nitrogen, carbon dioxide, etc.) and heavy hydrocarbons, the SRK equation of state has been combined with excess Gib...

Classification Performance Prediction Using Parametric Scattering Feature Models

We consider a method for estimating classification performance of a model-based synthetic aperture radar (SAR) automatic target recognition system. Target classification is performed by comparing an unordered feature set extracted from a measured SAR image chip with an unordered feature set predicted from a hypothesized target class and pose. A Bayes likelihood metric that incorporates uncertai...
