    Chemical engineering research topics

    Hey guys, I am from a Canadian university and have just recently took the GRE (1480 for verbal+quant). I am thinking of applying for graduate studies in the United States, preferably tier 1 schools such as Princeton, MIT etc.. However, after doing some online research it seems that schools...

    Getting an old PLC onto Allen Bradley DH+

    Hey all, I am trying to get an old AB PLC-5/40 onto an existing DH+ for data communication (both ways). The PLC does not support DH+ natively like SLCs but it is capable of serial communication. I know that the 1770-KF2 DH+ & Serial interface module are used to bringing a computer into...

    Install MikTex first before you install texmaker or texniccenter

    install MikTex first before you install texmaker or texniccenter, then the program should automatically detect your latex distro and set the proper paths to build the document. If not, you have to set them mannually, however, you can still compile the latex documents in a command line...

    How Can I Share Files Between Two Computers on a Home Network?

    First, you need to make sure two of your computers are in the same workgroup, you can check this by Right Clicking the My Computers and go to Properties. Second, go to your LAN connection configuration, and make sure NetBIOS file transfer protocol is installed as one of the protocols for the...

    Opensource / Free / Trial circuit schematics drawing programs?

    Hello everyone, I'm looking for an program to do some rudimentary drawings of electrical circuits for an introductory electrical engineering course. I have come across some proprietary ones that are either very bloated, and hard to use, or just plainly too expensive for me to consider...

    Index Website: Learn How to Find Forgotten Files

    pretty sure that's an option most web servers disables by default, unless your web server supports virtual hosting and you can write your own configuration for your custom domain. But like the other posters have stated, this is a major security risk and I rather have it disabled than to have...

    Which discipline to specialize in engineering?

    Hey guys, at my university (university of Alberta, Canada), we have a 1st year general engineering program, then you get to pick your discipline, right now I'm still unsure of what I wanted to go into exactly, I've been having conflict with "picking the right choice" and pick "what i love", so...

    Single Slit Diffraction and Huygen's Principle

    Hey guys, We are going through single-slit diffraction recently in Physics, I understand that using Huygen's Principle, we can treat the slit as a series of segmented wave sources, and they will interfere with each other based on their phase difference because of the path difference they...

    Is Your Dell Desktop PC Mismatched for Gaming?

    Wow, you really are a mad scientist. I don't mean to crush your hopes or anything, but consider the following: -Parallel processing only gives you more threads so you can run many processes simultaneously, it doesn't actually make the computing go faster. -Even if it does make your game run...

    Is Releasing Hydrogen Ions the Defining Characteristic of Arrhenius Acids?

    According to the Arrhenius definition, an acid is any substance, which when dissolved in water, tends to increase the amount of H+ so my guess would be that C is always true, the others aren't necessarily true.

    Proving the Integral of a Product using the Fundamental Theorem of Calculus

    Homework Statement Prove that f(x)g(x)-f(0)g(0)=\int^{x}_{0}f(t)g'(t)dt+f'(t)g(t)dt Homework Equations Basically, the question also tells you that you should somehow use the fundamental theorem of calculus. The Attempt at a Solution This is pretty much asking me to prove that the...

    Nth derivative of a trignometric function

    The question is uploaded as an attachment. By looking at the question, I can see that the number of terms of the derivative of this function is increasing exponentially, but since there's a product involved, I'm having problem finding a pattern..But i can see it has something to do with the...

    Proving a fixed point on a function

    Hello guys, this question is kinda bothering me since I'm having trouble with one of the steps in proving it. The question reads. Assume funciton f is continuous on an interval [0,1], such that the range of f is contained within or equal to [0,1]. Show that for a value of c contained within...
