Measure of Correlation between River Flows Using the Copula-Entropy Method
Publisher: American Society of Civil Engineers
Abstract: Analysis of the dependence between the main stream and its upper tributaries is important for hydraulic design, flood prevention, and risk control. The concept of total correlation, computed by the copula-entropy method, ...
A Change-Point Principal Component Analysis (CP/PCA) Method for Predicting Energy Usage in Commercial Buildings: The PCA Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method for predicting daily whole-building electricity usage in a commercial building has been developed. This method utilizes a Principal Component Analysis (PCA) of intercorrelated influencing ...
Load-Dependent Mechanical Behavior of Membrane Materials and Its Effect on the Static Behaviors of Membrane Structures
Publisher: American Society of Civil Engineers
Design Flood Hydrograph Based on Multicharacteristic Synthesis Index Method
Publisher: American Society of Civil Engineers
Abstract: Flood events consist of flood peaks and flood volumes for various durations that are mutually correlated and need to be described by multiple variables. Conventional flood frequency analysis methods are generally based on ...
Bivariate Flood Frequency Analysis with Historical Information Based on Copula
Publisher: American Society of Civil Engineers
Abstract: Flood events consist of flood peaks and flood volumes that are mutually correlated and need to be described by multivariate analysis methods, of which the copula functions are most desirable. Until now, the multivariate ...
Determination of Input for Artificial Neural Networks for Flood Forecasting Using the Copula Entropy Method
Publisher: American Society of Civil Engineers
Abstract: Artificial neural networks (ANNs) have proved to be an efficient alternative to traditional methods for hydrological modeling. One of the most important steps in the ANN development is the determination of significant input ...
Air Data Estimation Algorithm under Unknown Wind Based on Information Fusion
Publisher: American Society of Civil Engineers
Abstract: Physical pressure sensors installed on a vehicle’s surface are the general way to find air data, such as true airspeed, attack angle, and sideslip angle. Under extreme flight conditions, failure of pressure measurements ...
Analyzing Factors that Influence Expressway Traffic Crashes Based on Association Rules: Using the Shaoyang–Xinhuang Section of the Shanghai–Kunming Expressway as an Example
Publisher: ASCE
Abstract: Analyzing the influencing factors in expressway traffic crashes is an important aspect of traffic safety analysis. This study examines detailed data from 217 crashes that took place from 2015 to 2016 on the Shaoyang–Xinhuang ...
Northward Shifts of the Sahara Desert in Response to Twenty-First-Century Climate Change
Publisher: American Meteorological Society
Drought Analysis Using Copulas
Publisher: American Society of Civil Engineers
Abstract: Droughts produce a complex set of negative economic, environmental, and social impacts from regional to national scales. The drought impact can be quantified using drought index time series. This study uses the monthly ...
