Dear R useRs, I have a problem with nls.lm function of minpackl.lm package. I need to fit the Van Genuchten Model to a set of data of Theta and hydraulic conductivity with nls.lm function of minpack.lm package. For the first fit, the parameter estimates keep changing even after 1000 iterations (Th) and I have a following error message for fit of hydraulic conductivity (k); Reason for termination: The cosine of the angle between `fvec' and an...

I am trying to fit a nonlinear regression to infiltration data in order to determine saturated hydraulic conductivity and matric pressure. The original equation can be found in Bagarello et al. 2004 SSSAJ (green-ampt equation for falling head including gravity). I am also VERY new to R and to nonlinear regressions. I have searched the posts, but am still unable to determine why my data come up with...

...that is something we will be getting to in other articles, for right now you'll just have to trust that there is a fit. For now, however, let's get back to excavators, the digging machines used for, but not limited to: Digging, demolition, minning, river dredging, heavy lifting, and with hydraulic attachments, brush cutting. It is these same hydraulic attachments that have expanded the use of excavators, far beyond their original use of excavation such as the Low-energy Planetary Excavator (LPE) proposed by NASA. The latest paper to be found on this Nasa proposal is for 2006, so the curre...

Dear all, I am new to R and to it's programming philosophy. The following function is supposed to work on a vector, but I can't figure out how to do that without looping through every element of it. Is there a more elegant way? Note: I have shortened it, so it is NOT correct from the pipe hydraulics point of view # Calculate wall friction factor # reynolds: Reynolds number # dk: relative roughness of pipe lambda_wall <- function (reynolds, dk) { z <- 1 result <- 0 for (Re in reynolds) { if (Re <= 2320) { # Laminar flow lambda <- 64/Re } else if (Re &...

As far as I can see, there are two options, use kea, but that is, in my opinion, like using the worlds largest hydraulic press to crack a nut, or use dnsmasq just as a dhcp server. Rowland

Hello LLVM team, our software FluidSIM (www.fluidsim.de) simulates pneumatic, hydraulic and electric circuits. For the mathematical models we use the language Modelica (www.modelica.org). We developed our own Modelica simulator which solves the dynamical created algebraic differential equation systems. One tool is our small JIT compiler, which compiles mathematical expressions li...
