RISA New Feedforward Neural Network Structural Learning Algorithm—Augmentation by Training With Residuals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A fully automatic feedforward neural network structural and weight learning algorithm is described. The Augmentation by Training with Residuals, ATR, requires neither guess of initial weight values ...
Recurrent Neural Networks for Fault Diagnosis and Severity Assessment of a Screw Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a method to diagnose the most frequent faults of a screw compressor and assess magnitude of these faults by tracking changes in compressor’s dynamics. To determine the ...
Modeling Mixed Flow in Storm Sewers
Publisher: American Society of Civil Engineers
Abstract: The blowing off of storm manhole covers may be attributed to the severe pressure transients that can occur during and after the transition from free-surface to pressurized flow in a sewer system. Observations from a physical ...
Bearing Localized Defect Detection by Bicoherence Analysis of Vibrations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For automatic detection and diagnosis of localized defects in rolling element bearings, bicoherence spectra are used to derive features that signify the condition of a bearing. These features ...
A New Sensor for Real-Time Milling Tool Condition Monitoring
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new sensor has been developed to automatically detect face-milling insert fracture, chipping, and wear. With a befitting PVDF (polyvinylidene fluoride) sensor, and an optical transmitter based ...
Nonlinear Continuous Dynamic System Identification by Automatic Localized Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes an automated localized modeling method to identify continuous nonlinear dynamic systems from their operating data. Using a method similar to finite element method’s automatic ...
On-Line Detection of Localized Defects in Bearings by Pattern Recognition Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For automatic detection/diagnosis of localized defects in bearings, a pattern recognition analysis scheme was developed for investigating vibration signals of bearings. Two normalized and dimensionless ...
Evaluation of Storm-Water Impacts on Larviciding Chemicals at Catch Basins for West Nile Virus Control
Publisher: American Society of Civil Engineers
Abstract: Methoprene larvicide is a biochemical insect growth regulator used in North America to control the mosquito population. It can be incorporated in clay pellets or chalks and dropped into a catch basin sump. The slow release ...
Function Space BFGS Quasi-Newton Learning Algorithm for Time-Varying Recurrent Neural Networks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a new learning algorithm for time-varying recurrent neural networks whose weights are functions of time instead of scalars. First, an objective functional that is a function ...
Hydrologic Performance of Permeable Pavers and a Dome Concrete Forming System: A Comparative Study
Publisher: American Society of Civil Engineers
Abstract: The hydrologic performance of permeable interlocking concrete pavers (PICP) and a dome concrete forming system (DCFS) was quantified and evaluated at a retrofitted residential laneway in Toronto, Ontario. The quantification ...
