Abstract The current paper deals with the performance evaluation of application three soft computing algorithms such as adaptive neuro-fuzzy inference system (ANFIS), backpropagation neural network (BPNN), and deep (DNN) in predicting oxygen aeration efficiency (OAE20) gabion spillways. Besides, classical equations, namely multivariate linear nonlinear regressions (MVLR MVNLR), including previo...

River ecosystems are often fragmented by artificial structures, such as weirs. For anadromous species, these structures can impede access to upstream spawning sites and ultimately lead severe population declines. This study focused on the freshwater migration of sea lamprey, Petromyzon marinus, an species threatened habitat fragmentation across its native range. To quantify cumulative impacts m...

The sluicing flume that was designed is less capable of silting up and losing its calibration than its counterparts of standard sharp-crested compound weir design. The laboratory work described here led to a refinement in the design in the form of a short flume set into the lowest section of a compound Crump weir gauging installation. Critical flow occurs near the exit of this flume, and it is ...

We investigate the x log x condition for a general (Crump–Mode– Jagers) multi-type branching process with arbitrary type space by constructing a size-biased population measure that relates to the ordinary population measure via the intrinsic martingale Wt. Sufficiency of the x log x condition for a non-degenerate limit of Wt is proved and conditions for necessity are investigated. GENERAL BRANC...

<p>The Sukabumi (Baros) – Sagaranten Km Bdg 115+200 road section which is located in Regency a for the province of West Java. Because always damaged due to being eroded by water infiltration rice fields that seeps into body area at location and soil tends be unstable based on results lab tests having shear angle value 4.99ᵒ specific gravity 17.45, then it carried out analysis existing ret...

The aim of this work was to re-examine and update the airborne sampling data for some of the pivotal epidemiological studies that contribute to the dose response relationships in the quantitative meta-analyses of risk from airborne asbestos exposures. The analysis by Berman and Crump (2004) and Hodgson and Darnton (2000), in particular, looked at the sampling data available and combined this to...
