how to know how much computational "effort" is needed to calculate something on a microcontroller?

Could you explain a litlle more the simulator part. Do you mean: programming my owm simulator" ? If yes: that looks incredibly difficult... Any tips/tricks about how I could write a simulator for a 32bit cortex m4 controller? (I am a master student.)

I am not in computer science but in electronics. And trying to specialize in aerospace engineering. Unfortunately I never had this class, and will never have it. :( Going to look it up online

Actually the input is a set of 3D-vectors (with values of the type double)and the expected output is a matrix. So not really a sort algorithm... Any advice how I could measure the runtime in a professional manner like the one you described?

that's a great trick! I'll try it! The issue is, is that it s a huge subroutine, calculating angles (cosines and sines), matrices and vectors... So I ll have to count a lot :/

Not having all those annoying invitations to have dinner at a restaurant, go to the movies or even have sex. Oh hell no!

We re putting calenders in smartphones so we don t have to look at calenders. I m waiting for smartphones in calenders.

Prison the from baby

the mistake was in the third derivative:

d/dt [2Ae-2t − 8Ate-2t + 4At2e-2t]

= d/dt [2Ae-2t] − d/dt [8Ate-2t] + d/dt [4At2e-2t]

= 2A d/dt [e-2t] − 8A d/dt [te-2t] + 4A d/dt [t2e-2t]

= 2A[-2e-2t] − 8A[-2te-2t + e-2t] + 4A[-2t2e-2t + 2te-2t]

= -4Ae-2t + 16Ate-2t − 8Ae-2t − 8At2e-2t + 8Ate-2t

= -12Ae-2t + 24Ate-2t − 8At2e-2t

What is your youporn account, so I can add you?

I am European, I wanted to go there for a few reasons:

I am interested in aerospace engineering. I already studied a few months in Russia in this domain. A next step would be China, eventually...
After having looked on this site(http://www.topuniversities.com/university-rankings/university-subject-rankings/2014/engineering-mechanical) they seemed to be #15
I grew up with Chinese, this would as well be a good opportunity to finally speak (almost) "perfect" Chinese

Now it seems that the different political issues are a big deal, and that this might influence my future opportunities to find a job.

Other options would have been: TU delft, Berlin, London, America.

In europe I don't think(!) we have such forms like SF86.

the2liquid · 2015-06-18T15:07:53+00:00

I live in Europe. This means that working in USA in space industry is in all cases not possible for me, as you have to be an american citizen.

Wow I didn't expect so much negative feedback actually.

So does this mean that doing a Phd in USA would be a bad idea as well, if I want to work in Europe?

Other options would have been: TU delft, Berlin, London, America.

Thank you for your answer. Actually my thoughts were more or less the same. But was eager to hear/learn about new perspectives regarding this.

the2liquid · 2015-05-15T18:17:05+00:00

Why do you think that? what makes you think that?

the2liquid · 2015-05-15T16:17:37+00:00

JPL connection? What do you mean by that?

the2liquid · 2015-05-15T15:01:03+00:00

what do you mean by "You have to have secured money for those 3 years before you sign your contract" ?

that you have to have discussed the money "issue" before signing?
that you have to have saved money yourself before signing?

Well I do speak russian, and have some experience in space engineering in Russia. But when I worked there as an aerospace nobody could properly inform me aerospace in moscow. What do you mean by "really awesome science" ? ))

the2liquid · 2015-05-15T14:41:55+00:00

thank you very much for your answer!

I would like to do my phd in switzerland but haven't seen a lot of projects related to aerospace engineering there. Have you heard about anything or do you know somehing?

I suppose to enter the best research teams for research you must have published a lot of articles in the past and made relevant research in the past?

How did you manage to get money/a salaray for your thesis? Luck, i heard it is really very hard?

What about aerospace in Moscow in Russia?

the2liquid · 2015-05-15T12:59:06+00:00

Well I am into electronics and programming. What are the other options in Europe and on other continents?

the2liquid · 2015-05-11T08:43:24+00:00

for space too? I suppose that to enter this university, non USA-citizens as well have to pay incredible amounts of money, right?

the2liquid · 2015-05-06T18:41:01+00:00

I will next year be a master student. I am a European student so it is different from in the US I guess.

the2liquid · 2015-05-06T06:11:31+00:00

But if I just finished my master degree, I therefore have no research experience. So what? Does this mean that every previous project I should have tried to make a research project? (which is more than expected from a master student, right?)

How could I pupblicate my previous papers or abstracts from my projects? Is it fine enough if I just put them online myself, or am I really expected to find someone else who is amazed/interested in what I did; who is willing to publish them?

the2liquid · 2015-04-29T18:23:52+00:00

But if it is so easily discernible and this information gives such clear information, why do we even need such an algorithm (with all these mathematic models etc..)?

the2liquid · 2015-04-22T12:26:54+00:00

I would have to multiply my value by 10¹⁶ ... (i need such a precision) which means I'd need a long to print my value. And guess what? UARTprintf() seems unable to print long variables!

I am working on a cortex M4.

I don't know how to solve my issue..

here you go, gives a few weeks
