Based on multipotential surface theory, an elastoplastic constitutive model is established in this paper. The required parameters of the proposed are same as those Duncan-Chang model, and no longer restricted by generalized form Hooke’s law. In addition, uses a numerical method to fit test curves determine parameters. calculation program also developed FLAC3D, according comparison with triaxial...

The paper briefly reviews Duncan Dowson's ground-breaking contribution to the theory of elastohydrodynamic lubrication in relation understanding gear tooth contacts. His early work with Higginson on numerical modelling finally explained how gears can operate successfully, and avoid wear, due generation a stiff, protective oil film. resulting minimum film thickness equation stands as reliable re...

Land acquisition along the stream for angler access, streambank protection and habitat improvement began in the early 1960s. In 1985, a master plan for the stream was approved and these lands were consolidated into the Duncan Creek Fishery Area. The fishery area covers Duncan Creek from its headwaters downstream to 190 Avenue, immediately above Lake Como. Approximately 7.8 miles of the stream t...

Model trees are a particular case of decision trees employed to solve regression problems. They have the advantage of presenting an interpretable output, helping the end-user to get more confidence in the prediction and providing the basis for the end-user to have new insight about the data, confirming or rejecting hypotheses previously formed. Moreover, model trees present an acceptable level ...

Wemeasured the effects of divided attention on the aggressive behavior of a 20-year-old man within a testcontrol functional analysis (FA; Iwata, B. A., Duncan, B. A., Zarcone, J. R., Lerman, D. C., & Shore, B. A. (1994). A sequential, test-control methodology for conducting functional analyses of self-injurious behavior. Behavior Modification, 18, 289–306). The FA confirmed that divided attenti...
