I've set up a mail drop for us ugresearch@mogli.rutgers.ed Anything sent to this address will reach everyon who signed up last night. I will not moderate the list, but I have some guidelines for what should appear there. The info posted should be related only to special problems projects and/or group technical projects. It should not be repository for general news. Why? My disk space is limited and such posting will clutter the disk. Speaking of which, I'll be soon setting up an archive on my home page which will contain all our past correspondence. So far we've talked about the following as project possibilities; 1) REMOTE CONTROL PROFESSOR CONTROLLER: each student has a transmitter with two buttons. Button 1 says "speed up" and button 2 says "slow down". A box at the front of the room registers the votes and indicates whether to speed up or slow down. This could be a multiple person project (maximum of 3 I think) 2) WEB DISTRIBUTION OF COURSE MATERIAL: the student would prepare a lesson (module/lab, topic) for distribution over the WWW. The parameters of exactly what would be involved are open. What I'm looking for is a self-contained tutorial unit that students could use to learn material in various courses or extend their understanding. If enough courses could be covered, I believe this could blossom into a hallmark NSBE project with (I'm not exagerating) WORLD CLASS IMPACT. 3) CAMERA ON A BOOM: A remote access camera with a controller would be used to move a camera around and look "from afar". I gave the example of a camera in my office with which I could look at papers, but the context could be anything really. This would be agood project for about 2 or three students. 4) SKI-DOMETER: A device which could be mounted on a ski which measured snow speed. Current versions are mechanical. I envision something a bit more sophisticated which uses optics (leds) to measure speed Now, here are the caveats. It looked like more than 40 people in the room last night from various disciplines. Unfortunately, I'm only one person, so I don't see having more tan about 5 or so students as special problems students under my sole direction. HOWEVER, if we can figure out a way to do group projects along the lines of the web distribution stuff above, we might be able to achieve departmental "buy-in" from various departments. That is, your home departments would LOVE to have such web distribution of coursework and maybe we could work out a deal where I'm the secondary advisor and you hook up directly with a prof in your department. So that's the scoop. If you're interested in doing special problems, submit a proposal to this group so we as a group can tear it apart and rebuild it into something wonderful. Post questions/clarifiactions etc as well. If you wnat more detail on my background (technical) chck out my web page (http://winwww.rutgers.edu/pub/about/people/staff/crose/crose.html).

The mailing group is ugresearch@mogli.rutgers.edu and I'll post your last suggestion to it. However, I'm not sure I see the relation between traction and area. Larger area means less force per unit area. Friction is proportional to force per unit area. I do understand that two wheels tend to induce more frictional drag more than one, but even there, I'm not sure of the physics. In any case, were you to explore this, we (or you and a mech E prof and me) would need to understand/figure out the physics of the situation. Please send further explanation if you'd like (to the group). I may end up making sub groups by discipline, by the way if that's a collectively good idea.

As for communications, it's really very simple. The trick is knowing what is really important. For example, the sifting property of impulses is really important and so is the bit about duality and multiplication in time domain mapping to convolution in frequency and vice versa. It you know those basic properties COLD then you're way ahead of the game in AM (and NBFM) modulation. You should know in your sleep at 3am that the transform of cosine looks like goal posts at the frequency of the sinusoid. Likewise, you should know that sine looks almost the same, but with one of the posts pointing down. By the way, the sifting property is the one with an impulse when convolved with anything else gives a shifted version of the "else" it was convolved with.... for example delta(t-t_0)*g(t) (where * is convolution) gives g(t-t_0) as a result owing to the sifting property. Thus when we multiply g(t)cos(w_0 t) you get something that looks like G(w-w_0) + G(w+w_0) in frequency domain because you convolve G(w) with two goalpost delta functions. In any case, almost all FM and AM modulation can be boiled down to a few linear systems facts (there are a few others like the properties of transforms of real signals... conjugate symmetry... which are useful for singl=sideband AM... but it's not a large number of facts). You could start by asking me some specific questions. It's MUCH easier to use email since I'm not in and free that often. Now as for special problems, I'll leave that ball in your court. Suggest a project when you want to (post to ugresearch@mogli.rutgers.edu) or express interest in one of the projects that pops up on the group. Gotta go... will be away this weekend so I won't be able to respond to mail... sorry bout that.

By analogy, there is a whole lore about throwing a baseball (curves, sliders etc) and then somebody actually analyzed it (Terry Bahill at U Arizona) and figured out some of the basic principles. So, what I'm suggesting is that with anything we do we need to understand the underlying physics in order to be a valid special problems. As for the car battery, that could be done. However, I think a more interesting project would be to design a car-theft protection device which was more secure than what we've got now. What I'm talking about is that anybody can listen to your code and if they duplicate it (radio frequency tones) they can turn off your alarm (or open your garage door, etc). A more secure way to do this would be to have a query-response system where you press your button to send the unlock message and the lock sends a question back to you which you must answer. If you answer it correctly, then the lock unlocks. If not, then the alarm wails. When I say "you" I really mean the hand-held transmitter is formulating answers to the questions. This would be a lovely EE sort of project but not much ME content (the connection of an alarm circuit to a switch which shut off battery power or something else is pretty trivial). So, I encourage you to start putting pencil to paper and trying to analyze (using basic ME/Physics principles) all your ideas. For example, you mention handling is better with a lighter wheel. WHY IS THAT? I can think of a few physical reasons (which I'm sure you can come up with too), but I'm not really clear on the "handling" issue. How does one define handling? (think about this). What` is "good" handling. All of these must be quantified. Cheers, Chris PS: Please post responses to the group at ugresearch@mogli.rutgers.edu so everyone can get a crack at the special problems thought process and so that collectively we can distill good ideas into better ones. ******************** >From hussan@eden.rutgers.edu Thu Mar 6 23:23:56 1997 Return-Path: Received: from er7.rutgers.edu by MOGLI.rutgers.edu (4.1/25-eef) id AA19814; Thu, 6 Mar 97 23:23:56 EST Received: (from hussan@localhost) by er7.rutgers.edu (8.6.12+bestmx+oldruq+newsunq/8.6.12) id XAA03588 for Christopher Rose ; Thu, 6 Mar 1997 23:04:19 -0500 Date: Thu, 6 Mar 97 23:04:18 EST From: Hussan Peavey To: Christopher Rose Subject: Re: project Idea In-Reply-To: Your message of Thu, 6 Mar 97 21:31:54 EST Message-Id: you might be right, But if you create a wheel that was as light as to sigle wheels, I thought it would in crease handling also... I'm not sure...I guess we could go over that more! Another Idea! I always tried to figure out a way to stop the theft of car.... The best Idea I came up with were, a battery that dis- ingaged when the car was turn off... image the two connectors to the battery... that are computerized, and can only be reingaged with a code... like on the lock of a car! i belive this might be more feasible... but also vage in great detail! making you help and anyones elses to confront this the better! Subgroups sounds find for this idea i need a EE's help! more Ideas to come! need help to make them work though1 thank you Hussan!

I'm hoping you students will lead the profs of the world into the next century with a bang when it comes to how to present material. When you think about it, we've been learning in basically the same way for probably more than 10,000 years. COuld be that lecture and lab is optimal for humans, but probably not. We now have a chance to bring serious education to a lot of people at very low cost, so we should figure out how to do it right.... which is where you come in.
