Preparing individuals for productive work and a   high quality of life in
today's society is a complex  challenge for schools and corporations. To meet
this challenge, Northwestern University has established a unique Ph.D. program
in the Learning Sciences. Its purpose is to advance the research and
development of innovative educational structures and technologies.

Research in the Learning Sciences is aimed at creating environments that offer
all students a rich variety of opportunities for learning to think effectively,
both within and outside of formal learning settings. Graduate student and
faculty research efforts are supported by a multimedia, networked computing 
infrastructure and an unusual commitment to developing technologies that
function effectively within their intended settings. 

The Learning Sciences is a synthesis of computational and social science
disciplines including artificial intelligence, cognitive and developmental
psychology, educational research, linguistics, computer science, anthropology
and fields that develop strategies for teaching complex subject matter. 

Through research, field work and apprenticeships, the Ph.D. program will
prepare its graduates to assume leadership roles in advancing the scientific
understanding and systematic practices of learning and teaching.

Students are eligible for competitively-awarded multi-year funding. To qualify
for financial aid, candidates should apply by January 15, 1993. Applications
received after that date may be  considered. Individuals with relevant teaching
experience or a strong academic  background in a field related to the Learning
Sciences are encouraged to apply. For  application materials or for further

interactive user interface editor, interactive image display 
programs, surface visualization, an extensive library of image 
processing, numerical analysis and signal processing routines, 
and 2D/3D plotting packages.  X applications built using the Khoros

Simulink for Windows seems to run slightly faster than the dos version. Maybe
due to faster graph plotting. One disadvantage is that while it is plotting
graphs, the processor is kept so busy that you can't switch to other windows.
The other complaint is that the command window always flashes twice whenever
you press the return key. And yes, text editing is still excruciatingly slow
on a 486.

While it appears that this will work, the cost is a little

I think that ACSL also has an interface to MATLAB and therefore the

 I am recording the 6D position (x,y,z,roll,pitch,yaw) of an object
 using two independant devices. Since these devices have different
 reference frames a transformation matrix, call it X, must be
 calculated. To calculate X, the equation AX=XB must be solved, with A
 and B being known 4x4 matrices. I have found two methods which claim to
 solve for X. They were proposed by Roger Tsai and Reimar Lenz (June
 1989 IEEE Transactions on Robotics and Automation) and by C. C. Wang
 (April 1992). Both of these methods work if I pre-define X and create
 some 'cooked' data around it, however when I use actual data that was
 recorded using teh devices I get an incorrect answer. The devices being
 used are any two of : Northern Digital's Optotrak, Logitech's 3D mouse,
 and Polhemus Fastrak. I feel that the inherent error in these devices
 may be too great for the methods being used.
 I would appreciate it if anyone has information regarding these methods

I recommend you to use simulink (simulab).

ACSL is a simulation language. It runs on workstations.

Simulink is an easy to use software built on X windows. You may learn 
and be expert of using it in a short time. It can be run on workstations,
PC, and Mac. In addition, it conducts live simulations that display 
your result during the simulation. You may change your model parameters 
and see the result immediately. The function of the simulink can be
extended by using C, FORTRAN and matlab M-files.

I have used Simulink/Simulab for the past 2 years, both for simulating
non-linear systems and for developing models for use in H-infinity
and mu-synthesis design work.

On Unix workstations Simulink is a fine product.  It is extremely easy to
build complex models.  It lets you fairly easily incorporate user defined
blocks and functions - either using the Matlab programming language or
using C.  I have not used the C option but have extensively used the 
Matlab programming language.

One valuable advantage to Simulink is that the graphical block diagram
is stored as an ASCII .m file.  Depending how you pass parameters into the
block diagram you can set it up so that ALL the info on the system you are 
simulating is contained in the file.  The .m file provides complete 
traceability for the simulation results.  The fact that the file is ASCII
just makes it easier to extract this info later if desired.

I heartily recommend Simulink, but am going to list what I know of
problems or areas I think need improvement:

--Occasionally (1 or 2 times/week) I get a segmentation violation and have to
exit Matlab & reenter.

--Within a function there are limits in what you can do to modify parameters
for a simulation run.  This is not a big deal running time domain simulations,
it is a big deal in developing functions to design controllers based on
linearizing a Simulink block.

--On the PC/Windows version the Simulink window editing is aggravatingly slow 
on a 25 MHz 386 machine.  It may be acceptable on a 486 machine.


I have only a little experience with ACSL, mostly with their first release on
the workstations.  I was not happy with it at all, it was very cumbersome to
use & used single precision variables.  I understand the product has changed
 substantially since then.

One big benefit I see with Matlab/Simulink is the availability of supplemental
toolboxes which can be used for associated design & analysis.

I don't know of anyone who sells these, even as kits, but here are
some ideas:

1. Instead of the ball-screw drive, why not use an aircraft steel
   cable string between two pulleys/bobbins.  This is the kind of
   approach I've seen in most pen plotters for moving the pen, and in
   a few printers for moving the printhead.  It seems to work well,
   without much stretch.

2. Another possibility - a Gilmor (spelling?) belt between pulleys.
   I've seen these in a lot of lower-priced printers.  These are the
   toothed flexible belts, where the pulleys may or may not have
   teeth that mesh with the belt.

3. Instead of the pot for the pivot, you consider one of HP's cheap
   optical encoder pot replacements.  They are probably rather more
   expensive than a pot (I think about $20), and need a decoder chip,
   but are quite precise and have really good repeatability.  We used
   these in one of our projects with good success.
