Split Definition and 195 Threads

Hi all. I am currently in college and aiming to get a bachelors in biomedical engineering, however the thought of going into debt and not having a good paying job for a few years (not to mention working part-time) scares me. I have other debts I want to pay off and need a decent paying job to...

Sorry if i may sound little unclear, english is not my first langue. I I am looking for a way to create a circle that is in a square cut in 8x8 in matlab. I would be glad if someone could give me a hand. Thanks!

I am trying to convert a 240/120V 60Hz genset for international use, specifically for China at the moment. I need 50 Hz, which I can achieve by slowing the engine down and making the necessary changes to the voltage regulator in the generator. I can also adjust my Line-to-Line voltage to the...

during my reading of ender's game, there was a device that could split molecules and cause a chain reaction of destruction. this seems possible yet impossible to me. can such a weapon be created and if so what causes the reaction to be so destructive.

Is correct to afirm that a solution of a quadratic equation or is a complex number or is a split complex number?

Homework Statement If you have a 52card deck and split it evenly to 4 people (a,b,c,d) then what is the probability that persons a and b have 7 spades and person c has 3 spades. Homework Equations P(A) = |A|/|S| The Attempt at a Solution I divided up the decks 4 ways. So Persons a and b...

Does anyone know if they have considered using ultra high efficiency magnets to create an oscillating pulse into the energy of the electron orbital shells? This may in turn break the Coulomb barrier.

Hey guys I'm trying to figure out the ideal knee speed or velocity split for a particular car that I'm designing. What I'm trying to do is relate the knee speed (or crossover speed) of my damper to the crossover point in the displacement transmissiblity graph so that I can achieve optimum...

Hello everyone! This is my first post, I've done a bunch of searching on this forum which has yielded me quite positive results, so thank you for all of your posts which are a bloody gold mine of information. Although I've gotten quite a lot of information that has been useful, I'm still...

Hi, I want to varify something that I intuitively know (I think), that might not seem intuitive. If an electrical current is circulating and then it's path splits in two, where there is a circulating current. The larger current (black) will have to pass through this loop; what I want to varify...

Just a question How does solving the nonlinear schrodinger equation using split step Fourier method makes us understand the four wave mixing process in optical fiber ? Any examples on how that happens Thank you

I need urgent help! we have a beam made of some neutrons and some photons. I thought about the beryllium polycrystaline but I'm not really sure it could work. The beam has an energy of 2 MeV moreless. Sorry for my spoken english.

So if I somehow constructed a Freeze Ray that could lower someone's or something's temperature to absolute zero, would they split into subatomic particles ?

I am reading Paul E. Bland's book, "Rings and Their Modules". I am trying to understand Section 3.2 on exact sequences in Mod_R and need help with the proof of Proposition 3.2.7. Proposition 3.2.7 and its proof read as follows:I am having trouble in understanding the proof that condition (2)...

Homework Statement The Attempt at a Solution I'm doing a question on inclined planes and centripetal acceleration. I understand the question and what it's asking for, I'm just having trouble splitting F into it's x and y components and how 60 degrees related to it. Any help would be...

Could someone comment on, or perhaps help me fix/simplify/optimize/elegantify, a function I'm trying to make to split a string by whitespace into a vector of strings, discounting any whitespace in quotes? Intended behavior: name="someName" class="class1 class2 class3" id="someId"...

Hello. I was told that "in QM the information doesn't disappear". Does it mean that, in QM, the trajectory in the phase-space can't split? [The typical example is a vertical simple pendulum, with the mass above the spin-point; in classical mechanics you can't know if the pendulum will fall one...

when i use this MATLAB code but with rectangular pulse shape instead of chirped pulse i didn't get the predicted output , so is there a limitation with this method in case of rectangular pulse or the MATLAB code is wrong...

I think its fairly obvious to most people why a number being rational (or not) is extremely important. But I honestly do not see why being transcendental is as interesting of a property (though its clearly somewhat interesting). What interesting applications are there of knowing a number is...

Something that's been unclear to me from the presentations I've seen of interacting string theory: In a setting like bosonic string theory, where the interactions consist of strings splitting and joining, is it always possible for a string to split? In other words, are there "minimum-sized"...

Suppose I have a 10kW input. I want to divide the 10kW into two separate sources, like 1kW and 9kW. What can I do to separate the input into these different ratings?

http://forums.mikeholt.com/showthread.php?t=162981 I thought this would be a link worth sharing here on pf. We seem to have heated arguments going on this forum from time to time about which country has the best electrical system. There are some interesting things to read in the above link...

I have a boss subwoofer amplifier which I recently discovered was causeing the distortion I have been hearing in my car. this amplifier consists of a PWM powersupply turning the 13.5v from my on car to a +45 -45 power supply. Then there are 8 mosfet transistors, 4 in parralel powering one...

[b]1. Good day to all. Would appreciate all your help for my understanding please. I am quite new to this topic of fluid dynamics. a) Say i have a 1200mm pipe which eventually serves a main distribution network. However, I will close the valve to the distribution and allows the water to...

I just finished a preamp/active crossover using the lm833n but the amp I need to run it with is a class D single supply board. and so the ground on the board is just negative. Can I run my [high pass/ground/low pass] signal into this amp? they are sharing a 24v power supply though and if I...

Some years ago, I graduated with a degree in Political Science. My grades were...nothing special, C+ to B- average. How badly would that affect my chances at graduate school if I came back and just tore through the Physics curriculum with a 3.7-4.0 GPA the second time around? Assume that I...

I am reading Dummit and Foote, CH 10 Section 10.5, Exact Sequences - Projective, Injective and Flat Modules. As they introduce split sequences, D&F write the following: I am concerned at the following statement: "In this case the module B contains a sub-module C' isomorphic to C (namely C'...

Hello everyone, here is my problem I'm not sure where to start with this problem, I suppose if the phase difference due to the circulating current is negligible then the total phase difference can be written \Delta\phi_{tot}=\Delta\phi_{a}+\Delta\phi_{b}+ \Delta \phi_{B} In our notes we also...

I am talking about those 5pin AB amplifiers like the tda2030 for example. You can power them with posotive and negative 12v, which is equal to a total 24v, Or you can modify the circuit for a single supply, but if you do that so you can use a single supply12v, is it equivalent in output...

I was just wondering if ionizing radiation can split water into hydrogen and oxygen? Thanks in advance :)

Can someone please explain to me what is actually happening? OK so particles act differently when we observe them. So if I set up the double slit experiment in my room and left the room, came back and I'd see a interference pattern? If I stayed in the room, I'd see two lines of light? Do we...

I was reading an accident report where a process pump leaked from its delivery line through a "split flange assembly". The report further mentions: "Split flanges are not a good feature because they expose twice as much surface to the effects of corrosion" What exactly is a split flange...

Hi, I don't quite understand some central points of the many-world interpretation: When does the splitting happen, and is there superposition in a single universe? I see two alternatives: 1. There is superposition in a single, and this universe splits when we measure. This means we can...
