    Hot-Shot Civil Engineering Firms

    I know in many professions, such as Accounting, Finance, or Marketing, there are the "Big Firms" that pretty much hire the best of the best (Deloitte & Touche, Accenture, Proctor & Gamble, etc...). Many of those jobs are considered prestigious by their peers, and slouches typically need not...

    3-D dot product?

    I'd like to multiply a 1-D vector by a 2-D array without using a loop. Here's what I currently have: A = ones(10,10); z = 1:10; for i = 1:length(z) result(:,:,i) = z(i)*A; end Is there any way to do some sort of dot product between z and A that achieves the same result? Thanks

    Uniform Temperature Field

    Hello, I'm trying to perform a pixel linearity test on my camera, and I'd like to do it by imaging uniform temperature fields between 0 deg. C and 40 deg. C. Right now I am filling a glass fish tank with water and imaging the side. I'm trying to avoid reflection by covering it with duct tape...

    Writing to/Reading from a subdirectory?

    Hello, I have a program that outputs a ton of files. I'd like to output each file type to a separate subdirectory under the directory in which the program was executed. Additionally, since it reads in a ton of input files, I'd like to do the reverse and read them in from a subdirectory as...

    Reduce reflection on water surface

    Hello, I am a novice at infrared imaging, and I'm imaging water surfaces with an IR camera. I'd like to reduce the amount of reflection from things such as overhead lights, sun, etc.... I have successfully reduced it by covering the whole system with a dark fabric, but I'd like to know if...
