Thre rest of the circuit sure looks linear to me - a differential pair between output and a zenered reference that drives the output through an emitter follower etc. etc. The spec sheets shows the output imnpedance rising above 2000 Hz - could this be the source of the noise you see? Of course some clever manufacturer could have come up with an equivalent part that is a switching regulator as long as it meets the 78XX specs. -- Thomas Clarke Institute for Simulation and Training, University of Central FL 12424 Research Parkway, Suite 300, Orlando, FL 32826 (407)658-5030, FAX: (407)658-5059, clarke@acme.ucf.edu ------------------------------ Date: 16 Mar 93 22:09:50 From: Wales.Larrison@ofa123.fidonet.org Subject: A little less flame and more light, please?

Steinn Sigurdsson retorts: >Bent much metal recently? ;-) Ahem. Gentlemen, this argument is disintegrating into a set of personal flames. Could we get this back to a discussion of some semi-technical topics, or into a set of space policy options (with supporting technical/economic rationales), please? And by the way -- I also have a MBA (concentrations in Finance and Operations, with a strength in Strategy). And I also have 'bent metal' for spacecraft recently, as well as pushing paperwork as 'chief systems engineer' on a NASA contract -- which is currently on schedule and under cost. Which one I won't discuss -- but it's in excess of $10e6 and is scheduled for flight in the next year. I've also led "product development teams" which have designed and produced other pieces of space hardware - on cost and schedule for the DoD, NASA and commercial entities. Look -- a MBA doesn't make you a papershuffler. Nor does it make you a good 'manager'. What it does is give you more tools to develop a better understanding of the business and how what you are doing fits better into the overall program and business perspective. Some of the tools taught in MBA programs can be used effectively in aerospace development and production programs. Others can't easily be applied (My class in "Multi-National Working Capital Management", for example, even though the topic is fascinating....). Some of the tools can be directly applied (For example, the class I took in "Operations Analysis and Management Techniques"). Similarly, a Masters in aerospace engineering doesn't make you an expert on spacecraft design, nor does a Masters in political science make you an expert politician. In my opinion no academic education, by itself, makes you an 'expert' in any field. (I will admit there may be exceptions to this rule, particularly if the field is purely academic -- such as "History of the Romance Languages"). The academic educations provide tools and frameworks of organization of problems which can be applied to resolve real-world problems. IMHO to be proven an expert, one has to demonstrate that skill by accomplishments in the field. And I should add, you don't need an academic education to become "an expert", if you are willing to learn from your mistakes and from others. And you don't need to be an expert to have an opinion, or to be able to converse and argue intelligibly about a topic. However, there is a lot of "flame" in this forum at the moment. That flame is not contributing to the rational discussion of the topics being brought forward, an exploration of the differences of opinion or the sources of those differences of opinion, nor contributing to providing data for others on the net to learn from or establish their own opinions. What we've got is a bunch of opinions being promulgated as "sez me" "sez you" and semi-personal attacks (which are uncalled for at any time). Please, can we do better than this? ---------------------------------------------------------------- Wales Larrison Space Technology Investor --- Maximus 2.01wb ------------------------------ Date: Wed, 17 Mar 93 15:55:45 MET From: PHARABOD@FRCPN11.IN2P3.FR Subject: Aurora spotted ? I found in the popularization review "Science et Vie Junior", special issue "La vie extra-terrestre", January 1993, the description of an "encounter" which makes me think of Aurora: "Over the open sea: on September 2, 1990, a Boeing-727 of Air France, flight Strasbourg-Algiers, crosses the Mediterranean. On the radar on board, a mysterious echo, resembling nothing known, follows the same road as the plane. Speed: about 7,800 km/h ? The radar has been checked, it was functioning normally. What could happen is still unknown." (end of quotation) I have my own idea about that. 7,800 km/h = 4,850 m.p.h = about Mach 7 (like Aurora). Direction: Strasbourg => Algiers (between N => S and NNE => SSW), not very different from Scotland => Libya (NNW => SSE). Aurora is said to have a base in Scotland (maybe Machrihanish, Kintyre peninsula), and the US like very much to spy on Libya. Who disagrees ? J. Pharabod ------------------------------ Date: Wed, 17 Mar 93 18:01:15 MET From: PHARABOD@FRCPN11.IN2P3.FR Subject: Brontides Thanks to Mr. McElwaine (yes !) I found back a reference I was looking for. That's about the so-called (if my memory is good) "brontides". Here is the interesting (for me) excerpt from McElwaine's posting: > deployed beginning in the Fall of 1977. In late 1977 and > early 1978, there was a strange rash of giant AIR BOOMS along > the East Coast of the U.S and elsewhere. The AIR BOOMS were > never satifactorily explained, by either the government or > news media. They could NOT be positively identified with any > particular SST or other aircraft, and indeed were much louder > than aircraft sonic booms. I thought these booms happened in the mid 80s, therefore I could not find back any reference. Now I have found: "East Coast Mystery Booms: A Scientific Suspense Tale", by Deborah Shapley, Science, Vol. 199, 31 March 1978. Of course the explanation in Science is not at all McElwaine's theory (which unfortunately I have already forgotten, but which, IMO, will soon be posted again). Deborah Shapley reports three hypotheses: 1. Thomas Gold, professor of astronomy at Cornell, and Gordon MacDonald, a geophysicist, suggested explosions of leaked, airborne methane, coming from tectonic activity of the earth. Other scientists were skeptical. 2. The NRL (Naval Research Laboratory) suspected military aircraft flying at around 35,000 feet for brief periods of supersonic flight. But skeptics said these aircraft were doing that for about 15 years. 3. Jeremy Stone, FAS (Federation of American Scientists) director, and Richard Garwin, an IBM scientist, thought the Concorde was the cause of most of these booms. Turns south of Nova Scotia would have caused the booms reported there. Acceleration of Concorde off the coast of England would have sent shock waves which would have been bended down to earth by the thermosphere (altitude 100 miles) and could have hit the New Jersey or the Charleston area. But the Concorde flights have continued after 1978, and it seems that there were no more booms. Has anybody on this list heard of a more convincing explanation ? Regarding my own theory, which was that it was a precursor or a first prototype of Aurora, it seems not very good. The mid-80s would have been OK, but 1977-1978 is probably too early ... but who knows ? It seems that the 1991-1992 "airquakes" over California were not like those giant booms - these airquakes were described as short rumbles making the ground lurch. But maybe the boom over the Netherlands on August 19, 1992, has something to do with these "brontides" ? J.

The main advantage of the mule train approach is that there is minimal route preparation. You simply survey the route (with as many detours as necessary) and use 'dozers & dynamite where it's unavoidable. Of course, it could easily be the case that the terrain is much too rough for any overland route to be feasable. Having said that, I do like the pipeline. While the start-up costs are greater, the high potential throughput and low operating costs are attractive. To overcome the problem of freezing at night, the pipeline could be buried in the regolith (an excellent insulator). Does anyone know what the mean temperature of regolith is at, say, 2 meters ? The cost of ditch digging would have to be balanced against the increased capacity. Another potential problem solved by burying the pipeline is micro meteorite punctures. What is the flux of micro meteoites at the lunar surface ? Would it be a long term problem for an unburied pipeline ? Also, a pipeline would require some measure of refinement at the poles, as you do *not* want to be pumping muddy, gritty water. To take it a step further, you could perform the electrolosis at the pole and pump the H2 and O2 to the equator seperately, though that would be outside the scope of the design project. A separate consideration is the useful lifetime of the project (be it mule train, pipeline, or ice-flinger.) If the ice deposits will be exhausted in 30 years, a scheme with high start-up costs would be undesirable. Were the students given an expected life span or are they just assuming an indefinite period ? ------------------------------------------------------------------------------- | I shot a man just to watch him die; | Ross Borden | | I'm going to Disneyland! | rborden@ra.uvic.ca | ------------------------------------------------------------------------------- ------------------------------ Date: 16 Mar 1993 13:59:12 +0100 (CET) From: "Hans M.

Okay, so there's lots of paperwork, and reasons for it. But lately it seems like when something on a spacecraft is stuck, a mechanical problem, it was caused by a mallet whack, or the use of the wrong fastener, or something similarly trivial. Trivial until a multi-zillion-dollar vehicle has a mechanical failure. Let's say it was a whack with a mallet to get something to fit. After the deployment problem, this mallet whack is traced. Was this mallet whack noted in the paperwork ? If so .. Who signed off on it ? Wasn't there a procedure to require an assessment of the possible effect of a mallet whack ? Or did some assembly tech just do it and not have to tell anyone ? If the mallet whack wasn't in the paperwork .. Why not ?

It is important to distinguish between the paperwork being in order (we *have* document XYZ123), and the *contents* of the paperwork being in order (document XYZ123 maps to reality). I do not deny that it is necessary for any project more ambitious than an afternoon spent in one's shed to store (often boring) information in a more reliable and accessable form than the human brain. The trouble is that it is easy for management to become focused on paperwork rather than the real goals of the project. For an example of a pathological case of this see Richard Feynman's description of how NASA managers started with what they felt was a politically acceptable rate of launch errors (100000 to 1) and then fitted in numbers, running the engineering logic backwards, until they had inputs that produced the desired outputs. ("Fantastic Figures", page 177 of "What Do *You* Care What Other People Think.") In many ways the whole Process debate in software engineering is based on the (in my opinion wholly false) premise that one can find a series of rules and regulations for manipulating paperwork that will be completely self-encompassing, such that one *only* need take care of the paperwork, by following the process, and well engineered products will drop out as if by magic, with no intellectual effort, consideration of design compromise, or effort by experienced programmers striving for elegance. Indeed, one can run the whole thing with kids and pay them peanuts for their trouble. Paperwork exists only to serve the original engineering goals, not the other way around. In order for the paperwork to remain honest, it must be subject to continuous engineering scrutiny. We do not know how to systematise this scrutiny, and have to fall back on the diligence of experienced engineers when we apply it at all. When management (especially non-technical management) is motivated to track and operate through paperwork because the paperwork *is* easy to systemise, and the paperwork universe can be freed of much of the mess of the real world, it is difficult to find anyone to give the engineers a mandate to provide scrutiny with a brief that amounts to little more than "keep your eyes open and your sense of trouble keen," and back them up. I'll offer two further aspects of this view of the engineering vs. paperwork dichotomy. Firstly, the paperwork model stresses the depersonalisation of the engineering process. You are supposed to be able to mow down engineers as in the final scenes of "Zulu", and more will pop up and take over their paperwork. The paperwork also means that the structure and activities of the team can grow to the point where no one individual can comprehend even all the parts that they directly interface to. The engineering model identifies individuals motivated and able to have creative insights and organises their work such that they can see what is going on, so that their judgement and knowledge is applicable. Secondly, while it does nothing whatsoever to assist with the positive side of a project, the creative judgement I referred to above, the paperwork model does wonders when it comes to identifying individuals who can be deemed to be "at fault" after a mishap. The engineering model is to do with getting it right, the paperwork model is to do with getting it wrong. I have heard it argued that if everyone is busy covering their backsides then no mistakes will be made, but this is quite fallacious. Nothing would ever get done at all if people didn't take risks every day. My own opinions, not those of clients past of present.
