I'm trying to optimize a system of 10-20 differential equations in Matlab using a genetic algorithm. The problem is, when I call the ode function, whether it be ode45, ode23, ode15, etc., it sometimes gets stuck in an infinite loop. The genetic algorithm no longer progresses and I have to Ctrl+C...

If it's just splash protection, something set up like opposing paint brushes might work out pretty well. You see guards like that on the lever-style emergency brakes of some cars. You're a bit below the melting point of Aluminum, so it might be an option. Problem is, you're going to be...

First off, congrats on your scores and your decision to look at graduate education in ChE! I'd reframe the question that you're asking. What do you ultimately want to do when you graduate? Tier one schools, largely teach you to become a professor. They tend to have more ivory tower...

I think you're a bit confused about the tools you need to solve this problem. If I'm following you correctly, you are looking at a boiler that runs off of diesel and it is heating water, that in turn, heats your house via steam. The specific heat capacity (~1750 J/kg K) of the diesel is...

Is this seal meant to hold the pressure of a fluid? Or does it just need to provide a physical barrier, e.g., splash protection?

To quote a famous politician: "It depends on what the meaning of the word 'is' is." Mineral and rock wools contain some proportion of crystalline and amorphous metal oxides and, technically, contain ceramics. They are like the cotton candy version of ceramics -- full of air -- which gives them...

I've been trying to work through the heat equation given in this Sous Vide cooking primer: http://amath.colorado.edu/~baldwind/sous-vide.html It gives a modified version of the heat equation with a shape parameter for simplification. The equations are shown below...

Thanks so much! The Map function does it perfectly. -J

Thanks for the reply. But I think I was a little bit unclear on my first post. The third value in the list is a number, scaled between 0 and 1. So it's not a color name. And I want to show the intensity of that number with color. When I have the list of numbers, scaled 0 to 1, I can't find a...

I have data in x,y pairs that I am passing to the RectangleChart function in Mathematica. But I want to be able to color each of those rectangles using a third variable z. There seems to be no easy way to do this. I can't get the ChartStyle or Style options to add this color. Anybody know of a...
