    About Collision Cascades

    I have to do it from scratch since my programming abilities are very limited. I actually came up with a volume analytically using a maximum cascade temperature of ~10000 K, but the volume seems small ( V = 50 nm^3 ). Since I am trying to calculate the volume mid ion range, (about halfway...

    About Collision Cascades

    So I was wondering if anyone could help me out. I am trying to find a way to calculate the cascade volume in a steel alloy undergoing ~ 1 MeV ion irradiation ( Z ~ 25). For this analysis I will be looking at the electronic stopping regime with PKA energy of ~ 10 keV. Not sure what to do after...

    Hey Pounder, take a look at this program: http://bredesencenter.utk.edu/ese.shtml It's interdisciplinary and you will do research at a major national lab while going for your phd. You may also be able to work in the physics department while in this program.

    Modeling a crack in a material.

    I'm also wondering whether a crack exposed to damage becomes more jagged over time or more smooth? Is there a process that reverses the other one, i.e. from being more jagged to smooth, vice/versa?

    Modeling a crack in a material.

    I was wondering if anyone has ever tried to model/fit a crack on a material surface with a Weierstrass function.

    Do nuke plants hire PhD's in nuclear? I didn't think they did. But yeah, you're right, it is definitely not a hot time for nukes unfortunately.

    Engineering Find opportunities for future engineering PhD graduate

    Well, as of right now I think my focus will be nuclear materials and I am also at a college in the US. I hadn't thought of IEEE chapters, but I will give it a shot. What companies and industries are hiring nuke PhDs fresh out of school because all I see are national labs, the NRC or academia.

    Engineering Find opportunities for future engineering PhD graduate

    I was wondering how I could make connections in industry while still a PhD student. I know about job fairs and conferences, but are there other ways to make friends/contacts while still in the early stages of PhDdom so that I have viable options when I graduate?

    Question about emailing future advisor.

    Yeah, too true about showing respect, Marnemath. So when did you end up getting your advisor? That stuff looks great Jedishrfu, I'll have to check it out. Yeah, what you said about reading their papers is really good advice (something I should have thought of), so I will definitely get on it...

    Question about emailing future advisor.

    So I will be starting my Phd program in three weeks as a graduate intern. I was thinking of emailing my advisor with basic questions such as what I should be reading up on, relevant papers, what he would like me to get started on once I get there. However, I am worried that it will be...

    A single atom in a cold, closed, vacuum system.

    Thanks for the great info mfb and f95. I guess there is some type of "transition" between microscopic and macroscopic worlds in terms of thermodynamics. This is very interesting I suppose, since based on this discussion an atom could just remain in a very cold (~2 K), magnetically confined...

    A single atom in a cold, closed, vacuum system.

    Ah, thank you so much DrClaude, makes sense. However, how do you explain something ( a larger body) cooling off in the vacuum of outer space then?

    A single atom in a cold, closed, vacuum system.

    Heat cannot transfer from a hotter body(the atom) to the colder environment (the cooled chamber) by irradiation?

    A single atom in a cold, closed, vacuum system.

    Ah, you're right mfb about diffusion, so thank you. I guess my next question would be, could we apply an external magnetic field such that the atom is kept from hitting the container walls? In terms of how it cools down, I am just assuming that the system is already at that low temperature...

    A single atom in a cold, closed, vacuum system.

    Let us assume there is a single atom in a vacuum chamber which is kept at near absolute zero. Now assume the system is closed and that the chamber is large enough such that the atom cannot diffuse far enough to reach the walls. Neglecting other stochastic effects, what do you think the atom's...

    Schools University of South Carolina's Nuclear Program

    To add to what Thermalne said, if you want to do hardcore R & D at a vendor or national lab then I would highly recommend physically going (instead of an online program) to a reputed university such as Wisconsin, MIT, Michigan or Texas for a PhD.

    What is considered respectable coding abilities in industry.

    Yeah, sorry I wasn't very specific in my first post. Actually I will be doing a PhD in Energy Science with focus on nuclear materials. I guess I was looking for advice with regards to numerical languages for algorithms, design patterns and optimization. Thanks meanrev for the pages and I will...

    What is considered respectable coding abilities in industry.

    I will be an incoming PhD student this fall. I was wondering what programming skills I should pick up while a grad student. I was also wondering if someone could post an example code of what is considered good in industry.

    Good beginner math book on fractional dynamics

    I was wondering if anyone knows any textbooks that are a good beginners guide for the dynamics (mechanics) using the fractional calculus. I have The Fractional Calculus by Oldham and Spanier but was hoping to find something more rudimentary. Thanks.

    Yeah, 20000 sounds about right. Carlgrace, did they also pay for his/her tuition or did that person have to pay their own? Quarkcharmer, thanks for the website, I'll have to check it out.

    On fractal distributions.

    no, a mean value may exist for a power law distribution, however, for a fractal distribution, the data never converges on a mean value. Also, fractals obey a power law distribution, but not all power law distributions are fractal in nature. For the context of my question the pdf's I am...

    On fractal distributions.

    The data, as stated above, is the amount of long lines vs. short lines on a coastline (to use your example from before). You could also use data such as the times between episodes of the onset of rapid heart rate measured in patients (with a random sampling of people). Here there is no single...
