I started my PhD in CS at Brown in Fall 2006. I work on data processing, measurement, and model reconstruction from diffusion MRI of the brain.

You can find me elsewhere online:

There are a number of directories related to me on the CS filesystem, all of which are linked from file:///map/gfx0/users/jadrian

Generate a random filename from the command line:

set tmpfile=/tmp/`head -q -c 8 /proc/sys/kernel/random/uuid`

Rename files into consecutive zero-padded integers in bash:

let i=0; for f in *.JPG; do mv $f `printf "%04d" $i`.jpg; let i++; done

Test for host availability in tcsh (for loop demo; see here for bash example):

foreach h ( `cat hostlist` )
  ssh $h uname -n
end

Update a directory with stuff that exists in a CVS repository but not in the directory:
```
cvs update -d
```

Concatenate PDFs (more at the original source; even more elsewhere)

gs -q -sPAPERSIZE=letter -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=out.pdf in1.pdf in2.pdf in3.pdf ...

C = makecform('lab2srgb');
plot3(X,Y,Z,'Color', applycform([50+rand*50, -100+rand*200, -100+rand*200], C));

Recursively download a website using wget (see the man page for more)
```
wget -r -np -nH http://www.site.com/subdir
```

High b sensitizes to short length scale (Assaf & Cohen 1998, 2000).
The cingulum bundle looks like a long, skinny tube (that wraps around the top and back of the CC) in a gross segmentation, and fibers run along the long axis of this tube for most of this length. Their projections into the GM, though, are actually along the side of the tube, on mid-sagittal gyri. This is a really weird shape when it comes to inferring fiber paths from the bundle shape, so it should be a smoke test for any proposed system.
Sculpture might be a good choice for the second outside minor course. 3D reasoning, malleable shapes...
