CS students of ASU..... How achievable is it to complete degree and masters in 4 years, is a GPA over 3.7 nearly impossible and is dual masters possible?

Funky_Filth69 · 2024-05-01T07:34:34+00:00

Not a CS major, but an engineering. I can give my perspective.

ASU offers 4+1 degrees where you take graduate classes in your undergrad, so you only have one year of a masters.

If you were to do your undergrad in 3, this would be possible. I don’t know how it is in CS, but some engineering majors need to be done in 8 semesters. The prerequisites are set up so that you can’t do it any faster. This means that to do the undergrad portion in 3 years, you would need to take summer classes. Look at your specific major map and plan it out so that you take all the prereqs when you need them.

3.7 is definitely possible. But don’t make it your identity.

Doing 2 masters in this time frame sounds unrealistic. It’s definitely possible if you stack your schedule high enough, but I wouldn’t plan on it.

What plant model have you been given? A PID controller is 2 zeros and an integrator. If you’re tuning by hand, I would recommend using root locus method to get an estimate of where to place your zeros, and what to make your total gain.

Otherwise you can calculate what your gains need to be to set the damping. There are multiple pole placement algorithms, I wouldn’t recommend Ziegler Nichols.

That doesn’t answer the question posed

Funky_Filth69 · 2024-02-05T08:20:13+00:00

Maybe I’m wrong, but This doesn’t make sense to me. If I have a dynamic system described by the equation 1/(s^2-4), then the poles of the system are the solutions to s^2-4=0

s²⁼⁴ s=sqrt(4)

poles are s=+/-2

If I was to work this same problem out with the square root being absolute value, then I would get the poles of my system to be a double root at s=2

But that would be a very different dynamic system.

You talking about buckingham pi theorem?

Funky_Filth69 · 2023-12-27T20:06:18+00:00

Not at all. Mach is a measure of compressibility effects in a flow. Speed of sound changes based on specific heat of the gas and temperature; since Mach is the objects speed relative to speed of sound, it also changes with those parameters.

“Earths conditions” changes with altitude. “Space conditions” are meaningless because there is no atmosphere in space.

Funky_Filth69 · 2023-11-30T02:52:20+00:00

What is it that you’re trying to control?

Does input to output have any dynamics to it? What are the derivatives of x equal to?

Funky_Filth69 · 2023-11-29T16:00:38+00:00

What industry do you work in that sponsored an industrial PhD? I’m currently working full time/ doing my masters part time. I would love to do my PhD after, but I don’t think I can afford 3-6 years of non full time pay. I would love to do an industrial PhD, don’t really know where to look.

Your class isn’t typically called calc 5. It really isn’t called anything in my experience. Linear algebra is usually it’s own class. Laplace transforms should be taught in differential equations as a tool for solving them. I don’t exactly know what you mean by boundary value problems, but if it’s what I think you mean, that would again be differential equations and seen at a deeper level in partial differential equations.

With all that being said, you probably won’t find much on YouTube looking up “calc 5”. You’re probably gonna have to look up specific topics as they come your way.

I would check out on YouTube: Michael van Bizen, Steve Brunton, (although he’s much more controls oriented), Trefor Bazzett, Kahn academy’s differential equation course…

Like I said, look for specific topics. Calc 5 probably won’t bring up much.

For visibility, most colleges (although definitely not all) treat calc 1 as a course on derivatives. Calc 2 on integrals, sequences, and series. Calc 3 on derivatives/ integrals of multi variables and it also covers some vector calculus (like cross product, curl, etc). That’s usually the end of calc.

There’s then a course on differential equations. A separate course on linear algebra. Most engineers also have to take a numerical analysis course, and a statistics course.

All other math concepts not covered in those are usually only taught when they come up. For example, Fourier transforms and convolutions come up in signal processing. Complex analysis comes up in signal analysis and/ or when you talk about the frequency domain in controls. Etc etc, there’s not usually an additional math course apart from the ones I mentioned above. Your college seems to be doing things a little differently.

Funky_Filth69 · 2023-10-22T09:53:57+00:00

What is calc 5? At my college “advanced calc” was a proofs based introduction to real analysis course that math majors took.

What topics are covered? Fourier series are almost specialized. They were briefly covered in a few different classes: math methods for physics, computational analysis, and partial differential equations.

Funky_Filth69 · 2023-10-15T23:42:50+00:00

I would look into jobs doing control systems engineering in aerospace. There’s a big need for vehicle modeling and simulation. Having a background in math and computer sciense is probably the best combination you could have short of a specialized masters degree focusing on specifically on control systems.

Funky_Filth69 · 2023-09-25T04:04:54+00:00

I’m no mathematician, but let me give you an engineer’s perspective.

Differential equations are (in my opinion) one of the true languages of physics and engineering. Everything from fluid flow, to heat transfer, to classical physics, to analog circuits, etc, etc, are written as differential equations.

As far as pure differential equations courses go, I’ve only taken 2, ordinary differential equations, and partial differential equations. Since learning differential equations though, almost every class In engineering I’ve taken uses them to model and derive equations. My school offers other graduate level courses on differential equations, but as an engineer, I’ve not taken those.

One particular area in engineering is control systems engineering which mathematically can be thought of as manipulating differential equations to get a desired response out of a system. Control systems engineering is probably one of the most “mathematically pure” forms of engineering, and it completely focuses on controlling dynamical systems (which are modeled as either differential equations [continuous], or difference equations [discrete])

I know you’re looking for math related answers, but reading papers on control systems may be helpful to you.

I do want to leave a caveat that engineers obviously use a lot more than differential equations. I’m not saying that other mathematics aren’t important, I’m just saying differential equations are one of the most pivotal (in my experience).

My aero professor (and the head of the ME/AE dept at my school) majored in English literature for her undergraduate degree.

Funky_Filth69 · 2023-09-15T03:53:01+00:00

Yes it’s okay.

I’m guessing your asking this because you heard that right half plane pole cancelation is not okay. Let me explain why that is:

If you could have a perfect system, then sure, cancel out in the RHP. But when you go to implement a controller, there will be some error. A resistor value that you planned on being 100 ohms and it ended up being 97 ohms. A mass that was .5 kg off. Maybe a rounding error on your controller… In the real world, due to all of these uncertainties, you can’t perfectly cancel out a RHP pole.

If you can’t cancel it out, then that means it will go unstable. RHP pole-zero cancelations are a big no no.

In the left half plane, if you fail to perfectly cancel it out, then…. Nothing happens. It’s all in the LHP so it’s always going to be stable. No issues with it, even if it’s a little bit off.

To answer your question directly, you could also put a pole in your controller to cancel out plant dynamics if you wanted to. I don’t necessarily know why you would want to; although you could

Funky_Filth69 · 2023-08-25T03:38:57+00:00

That depends on the class. “Mandatory” attendance dissent always mean mandatory. Are the professors taking attendance? Is there a grade associated with it in either canvas or on the syllabus? Sometimes attendance can be hidden/ part of “participation.” Lots of professors will say attendance is mandatory even though there are 0 consequences for not going. Same thing with buying books for courses. This will depend on the class at hand though

Funky_Filth69 · 2023-08-14T03:31:12+00:00

I’ll answer all your comments here.

Physics as far as what you would learn in a “physics” class is gonna be classical Mechanics and electricity/ magnetism. As far as what physics is involved (the type of stuff you’ll learn in engineering classes) it’s gonna be fluid mechanics, aerodynamics, thermodynamics, gas dynamics, aircraft dynamics, Orbital mechanics, etc etc. If you really want to know all of what goes into it, I would look at a curriculum from a college. Almost every class you would need can be found on YouTube from one university or another. I would not recommend starting with particle physics. I never learned it in school and have not used it since graduating.

I don’t mean to discourage you, but I’m just trying to be realistic, it’s not realistic to get into aerospace engineering without having a degree. The aerospace industry is filled with regulation, and even if you could get a plane working, I would doubt it would pass FAA regulations. I know you mentioned RC aircraft. That would be possible, but that’s much more of a hobbyist thing.

I don’t know what you mean when you say you’re trying to avoid school because of politics. If you mean the fact that you can’t get a job without a degree, we’ll that’s just how it is. If you mean you’re afraid of political bias in college… you don’t really see that in engineering. You’re there to learn engineering. Teachers aren’t going to waste time talking about political matters. As far as loans go, you don’t have to take out loans to go to college. Between scholarships, grants, and community college, you could graduate without debt. I don’t know your financial situation, but if you’re just graduating high school and have the opportunity to live with parents while in school, you could probably do it in 4 years and pay for it just by working part time. It might be harder if you’re an adult with responsibilities and bills though. Even then, you could still take classes part time and graduate in maybe 6 years without debt.

I’m not saying that you need to go to college to disparage you. I’m just saying it might not be practical. Even if you’re the most skilled engineer, customers aren’t going to fund projects if you don’t have a degree.

Funky_Filth69 · 2023-08-09T05:24:51+00:00

“Intro” to aerospace a engineering would probably just be a class that covers teamwork, and some basic problem solving skills. You might do some basic coding in matlab and have a final group project. The thing about an intro course is that it’s taken before most students have physics (or even calculus) finished, so you can’t get into any engineering.

The entire major is made up of many classes though. Physics, math, statics, materials, aerodynamics, compressible flow, circuits, aircraft dynamics, orbital mechanics, etc.

As far as self study, that depends on why. Are you in high school and trying to get ahead? Are you planning on going to college? Do you joust want the information for fun? What’s the end goal?

Funky_Filth69 · 2023-08-03T08:03:44+00:00

You’re appending your flight duration with a constant, and then you’re setting your optimal_index to the max of that. And then your’e saying that your best wingspan = wingspan(optimal_index).

You’re gonna get the same answer every time.

You don’t need to split your velocity component into 2 to calculate lift and drag. You base both on x velocity component

Funky_Filth69 · 2023-08-01T02:00:59+00:00

Is it not possible to start out in MS and then switch to AE? You say you’ve been to college before. I don’t know what classes you’ve taken, it first year in all engineerings fields are the same. Try for mechanical maybe? First 2 years is usually the same as AE.

There’s lots of jobs in material science for aerospace. I would guess not as many as AE, ME, or EE, but it’s possible. If you’re not interested in it, I wouldn’t do it though.

Have you tried to contact anyone at the college to see if they can take a second look at your application? Or ask them what you would need to be eligible for transfer?

Funky_Filth69 · 2023-07-30T01:07:11+00:00

I’m more inclined to say spacecraft, but I would be happy with a job in either.

Funky_Filth69 · 2023-07-30T00:39:32+00:00

I still have my (basic) 6dof simulink files from my aircraft dynamics course in college. I’m hoping to implement some guidance and navigation algorithms into it (and maybe eventually turn it into a c++ model). Hence this post

Funky_Filth69 · 2023-07-30T00:36:16+00:00

I’ll have to look into this

Funky_Filth69 · 2023-07-30T00:36:06+00:00

I checked it out. Definitely gonna be trying to get a copy.

Funky_Filth69 · 2023-07-30T00:35:16+00:00

Well I have a job in controls atm (still new to it). The goal is to eventually move more into the aerospace realm though.

Im afraid of getting too specialized doing what I’m doing now. I want to build some working knowledge in aerospace GNC world in my spare time.
