    Is it possible to use multiple network adapters at the same time?

    Sorry, right. The machine that I'm sending files to is not the same as the one I am receiving files from, nor is it on the same network. Using separate drives shouldn't be an issue; I really just wanted to make sure that I would be able to handle switching between the two adapters in such a way.

    Is it possible to use multiple network adapters at the same time?

    My current problem: I have a machine sending a file every few seconds over its wired connection. While this is occurring, I want to be able to access a wireless network and download a file from a mapped network drive without interrupting the aforementioned file transfers. Any suggestions as...

    Finite difference approximation for third order partials?

    Yes but I don't have the function itself; I only have its value at various points i-2, i-1, i, i+1, i+2, etc.

    Finite difference approximation for third order partials?

    I'm attempting to perform interpolation in 3 dimensions and have a question that hopefully someone can answer. The derivative approximation is simple in a single direction: df/dx(i,j,k)= [f(i+1,j,k) - f(i-1,j,k)] / 2 And I know that in the second order: d2f/dxdy(i,j,k)= [f(i+1,j+1,k)...

    Convolution of discrete and continuous time signals

    Not a specific question per se but... Is it possible to convolve a discrete-time signal with a continuous-time one? if you have x(n) and y(t) can you calculate the convolution of x and y (say, by taking y(t) for t in the set of integers or by treating each x(n) as its value multiplied by...

    Is Every Convergent Sequence of Real Numbers Bounded?

    In my case {cn} need not be finite, though. Does that still hold in this case?

    Is Every Convergent Sequence of Real Numbers Bounded?

    Homework Statement If {cn} is a convergent sequence of real numbers, does there necessarily exist R> 0 such that |cn|≤ R for every n ∈ N? Equivalently, is {cn : n ∈ N} a bounded set of real numbers? Explain why or why not. Homework Equations n/a The Attempt at a Solution I would...

    Proving Inverse Matrices: Simplifying the Last Step

    It's not cut off. It's as far as I have gotten with the proof, haha. There is nothing obvious that jumps out at me when I consider the case where the exponential argument isn't 0.

    Proving Inverse Matrices: Simplifying the Last Step

    Homework Statement I'm trying to show that a given matrix is the inverse of the other, by showing that multiplying them together generates the identity matrix. I can't see a way to simplify the last step and I feel like I'm missing something..? Any input on this would be helpful. Thanks...

    Excel/MINITAB graphing - scaling the x axis

    You could change it to a histogram and adjust your values accordingly. It should have a scaled axis in that case.

    Understanding Integer Permutations: X Natural Positions Explained

    If, for example, your permutation is (2,3,1,4,5) then X = 2 because 4 and 5 are in their original, or natural positions.

    Probability Question (Random Variables and CDF)

    Homework Statement A transmission channel is noisy and a binary bit (assume it is a 0 or a 1) has probability of .11 of being incorrectly transmitted. Suppose the bit is sent n (odd) times and a majority decoder announces which bit is received the majority of the time. Assume retransmissions...

    Small, Lightweight Voltage Measurement Device for PC via USB

    Well, the thing is I'm looking to try and have wireless voltage monitoring. We've already got the wireless infrastructure working in the form of a USB device server which broadcasts to a router; hence I need an option that is as portable as possible. Spending $70 on a DMM for its PC interface...

    Small, Lightweight Voltage Measurement Device for PC via USB

    I'm looking for a device I can use to measure analog voltage (up to 25V) and send the data to a PC via USB. Only really need one input, though it wouldn't hurt to have more. My main concern is that it needs to be pretty small and light - any ideas? The few I've seen online are either too...
