Do you see what I mean by the baggage of our perceptions? Here we have the perception being put forward that "the Old Guard guys, who are traditionally sexist in every other way". I don't believe there is any malice involved, just that that is the perception you have. As you can see, this colours the way you see things. In the same way, those who see the three letters M, A and N used in sequence feel offended by it because they have the perception that its use somehow demeans females. Even of the letters were C, A and T, or D, O and G, a similar situation would result. Similarly there are people equally offended when the letters MAN are replaced by PERSON or something else, or the work changed entirely. We need to understand that the word is not the problem, it is simply a convenient hook to hang your coat on. When we understand this, maybe we will start to resolve things. Regards, Ian A.

I have used one of them and I'm happy with it. It uses a spiral wound cable as a push pull gear driver. The cable is in a fairly stiff flexiable housing that has to be ridigely supported every 4 feet or so. It makes a continious circuit around a gear at the handwheel operating station over to a simular gear on the remote valve and returning back to the handwheel station. The operator has lots of torque and is used by the U. S. Navy on board ships so it has to work pretty well. It is limited by short distances in that if the valve and the operator are too close to each other you don't get enough cable to achieve all of the turns necessary to full open a multi turn valve. The cable has a splice in it that cant pass through the gear.Return to Top

I was assistant city engineer of a small midwestern town awhile back...I'll never forget a conversation I had with the (male) personnel director one time. I told him there was a better expression than "workMAN's comp"--plenty of people who worked in the city weren't men. He was absolutely bewildered--"worker's comp" had never occurred to him. Moral of story--people will sometimes go for the sexist title even when it's a more awkward locution (like "draftsman" instead of "drafter").

But, but .... but, the word "draftsman" is just a title, meaning *one* who drafts. There is not gender associated with it at all. If one were to train a dog or cat to draft, it's still an appropriate title. Do not underestimate your abilities. That is your boss's job.

In reference to what the person who emphasized a DE over a PhD said, I'd like that person to give more background on who he is and why he said what he said and give some references for that emphasis. PhD degrees come out of "graduate schools" which are umbrellas over all departments except "odd" areas. A few schools may, out of convention (or maybe in certain parts of the world), a Doctor of Engineering or a Doctor of Science degree, instead of a Doctor of Philosophy. I have not been everywhere in the world, but I have rarely heard of substantial & meaningfulness to a DE vs a PhD. There are a few Doctor of Arts (a PhD without a dissertation) programs, and a PhD out of a college of education can be a EdD rather than a PhD. And out of professional schools the initials can be different (eg DDS, LLD, etc). And lastly, one can sometimes get a BA (batchelor of arts) instead of a BS degree simply by putting a checkmark on the graduation card (this was a fact where I got my BS degree) but otherwise little curriculum content definition was important. A BSx, where x= engineering (eg. EE, ME, etc) did have curriculum content requirements. I do not know the (mission-orriented) engineering field job markets like the (discipline-orriented) pure science job markets, but I would tend to expect that there are many more job openings for BS level than Doctoral level people. What kind of doctoral level may be much less important than a match between a specific person and a specific employer's needs.

Poetry for Problem Solving-4 SYNERGY Synergy is like combining 2 and 3 and getting 99. Far more comes out from the combination than you had any right to expect from what went into it. Synergistic systems have two or more somethings; elements, parts, processes, components or combination of these that, together, either produce far more or far different results than would be expected from the properties of either one alone. SOME PROBLEMS WHERE YOU SHOULD LOOK FOR SYNERGY Any process not performing as well as desired, such as: A process where a bottleneck limits performance. An unbalanced process where some parts aren't doing as well as the rest. A problem or task where multiple ways exist for doing the job. WAYS TO FIND SYNERGY Describe your system and ID those elements which limit performance. Then look for a complementary element that could eliminate the limitation, counteract it, or cut it down to size. Another way to achieve synergy is to have one process put the elements into a preferred condition so the other process can function much more efficiently. Employing a simple decision process that requires little intelligence or effort, can often eliminate lots of later work, or reduce the level of resources needed to do the work. WHY DOES SYNERGY WORK? Synergy results from two or more complementary processes. One process, independently, does something that aids the other in performing its task. For example, Ms. Spratt could only eat fat so she would leave 75 % on her plate for garbage. Mr. Spratt, aka Jack, could only eat the lean; so he would leave 25% in the garbage. However, their synergistic combination would result in a plate licked clean. No garbage at all. Highly efficient food utilization. Any time you have two or more processes which, together, meet all requirements, but individually can not; try and use them together. For example, in filing your nails, or milling a part, or solving an equation numerically; typically one should use two tools, one for the coarse work, and then one for the fine detail. Neither one is satisfactory by itself for the entire task, but the combination is great. OTHER PROBLEM SOLVING METHODS ARE CLOSE RELATIVES OF SYNERGY A. Catalysts B. Thresholding C. Orthogonal Operations OF COURSE THERE CAN BE PROBLEMS WITH OBTAINING SYNERGY You may not find complementary components for the current component. SYNERGY EXAMPLES Comedy teams with a "smart" and a "dumb" partner. Burns and Allen; Laurel and Ollie (the fat one) Song writers, one does words the other does the music. Rodgers and Hart, Gershwin and Gershwin, words by Ira, music by George! Then there is Cole and Porter who said "Why does it take two people to write one song?" To examine the actions of atoms near absolute zero COLD, like 0.002 Degrees above ABSOLUTE ZERO conventional cooling techniques used to get superconductivity just can't hack it.. The cooling alone can't get atoms to zero velocity; nor can Light Beams slow down a lot of fast moving atoms. However by cooling the atoms and then containing a few atoms in a cold chamber, one can use light beams to slow individual cooled atoms to near zero velocity and thus have them very cold Increasing speed of access by sorting data so that it can be accessed in a structured linear or simple algorithmic fashion rather than every time having to go through from the start. Stereochemistry is a way of maximizing the interaction of chemical elements. One aligns elements for maximal interaction by orienting pairs of elements for easiest mating. Like fitting together hand in glove. Holding or propping a door open so people stream through instead of each one having to stop to open and shut the door. Processing systems where early decisions reduce later work. High speed H/W can use simpler S/W for more complex applications. Intelligent S/W can result in simpler H/W. Compressing a data file, before transmitting it. Saves space and your time. Spices bring out the flavor inherent in some foods which have minimal flavor on their own. Something where there are two or more alternative/complementary ways of doing something. Generate a set of complementary or orthogonal functions, techniques, capabilities; for example: Electrical, magnetic, mechanical, chemical, and optical systems Computing vs. table look-up Feedback-Feedforward Random -Sequential Chaotic vs. structured Plastics vs. metals Aluminum vs. steel Active vs. Passive Early vs. Late Decisions Design Time vs. Run Time Functions A Process, for those who aren't process oriented, is the way you do your work, or the way a set of actions is performed to produce a result or a product.

As one of the above cited "mustangs," I submit that there is a qualita- tive difference between one who has the job title of Whatever Engineer, and has the title on his **COMPANY-PROVIDED** business cards (and, when appropriate, distributes those cards), and one who holds himself out as a Professional Engineer in private practice. Also, in my personal bali- wick (I'm a software jock.), there is a great deal of blather going on about "Software Engineering." Where are the EIT/PE exams/standards for Professional Software Engineers? If there are none, can I, upon my re- tirement from the corporate wars, legitamately, or even lawfully, set up a practice as a Software Engineer? (Sigh!)

This is a most interesting thread. However, no one gave an answer to the question, "When will the U.S. finally go metric?" My answer is, "never." A more meaningful question would be, "Why should the U.S. go metric at all?" There are no doubt many answers to this question, but my response would be that there is _no_ compelling reason for the U.S. to do so. The global economy and interdependence arguments are mere bogies. Up until about 1965, the U.S. was capable of manufacturing all of the goods needed/wanted by industry and the citizenry, respectively. In other words, an American could purchase a toaster, radio, automobile, or anything else he/she needed that was designed and manufactured in the U.S. using domestic labor and materials. I don't know what the U.S. population was in 1965, but it certainly provided a large enough market to sustain our industry. Our population is considerably larger today, so it would surely provide a more than adequate market for U.S. goods and services. The fact that this is not the case today is due to corporate greed and greed and shortsighted thinking on the part of politicians. If we wished, we could once again be a self-contained economy and society. The backlash against NAFTA and GATT are the first signs of our possible return to our former economic state of affairs. In such a situation, we can and will use whatever system of weights and measures we choose with impunity. If other nations don't like it, so be it. However, there is a more immediate reason the U.S. shouldn't go metric. Why should we use an inherently inferior measurement system?

INTERNET Some people prefear to go on thinking that the Einstein’s relativity theory is right , thinking that matter cannot reach and substain light velocity, because in this case matter would have an infinitive mass , and it would be necessary to transfer to it an infinitive quantity of energy to reach light velocity. At the same time the physics substain that at elemental material level the time does not exist and that in normal conditions it is not possible to travel in the time. As opposite to what mentioned before, the writer, after 20 years of research out of the pubblic ufficial circuit of the physical research, can prove that things are different. Some examples of his theories follows: -The conception of time and space given by Einstein Relativity is completly inconsistent applied to the case of light velocity of the matter and the time is translated by some physical, heavy consistent material particles but normally invisible. In many cases the theories substained by the physics are uncomplete or inadeguated to describe the reality, but because of their lack to give an explanation to the real phenomenons; they continue to substain that their concepts is the only truth, thing that is false in the reality. - The Writer gives some information about: 1) travels of matter at light velocity in present time, 2) the explanation of the natural composition of the elemental particles that translate the time in the matter, 3) the explanation of the forces unification, where it is explained the natural formation in the sub-elemental particles of the electricity, of the magnetism and the gravity, 4) explanation of matter at null temperature, where the quarks can be visible and free, because they are stopped in the space, expanded and enlarged 10(18 ) times or 1 billion of billions of times and they are freely visible at naked eyes for about 10 minutes and they reveal their true physical nature as physical particles. The Writer brings explanations and ascertained cases which confutate the Einstein’s relativity theory substaining that the matter can not travel at light velocity. The contrary is possible. It is given the right explanation of the whole physical world (included that the real physical structure of the space is " not "empty" , but it has a completly different structure " normally " not ascertainable "). End of December 1996 it will be ready a book , entitled "THE QUADRIDIMENTIONAL UNIVERSE", where in about 420 pages with colour photos and pictures , the writer explains these theories and many other concepts not already reached by the officials science.

My first attempt to post this message seems to have been offered as a sacrifice to the USENET gods. If it shows up, please ignore it. I have been using a high-end process simulator and have been very satisfied with it. Unfortunately, budget cutting might force me to a cheap low-end DOS-based simulator which I find unacceptable for my needs (not to mention the productivity reduction). My only hope is to find some cheap or public domain software or code to take up the slack. What I need is software that will do one or more of the following (in no particular order) : * Calculate and plot ternary VLE diagrams * Close material balances by the maximum-likelhood method (not least squares) * An optimizer to maximize or minimize an objective function (such as flow rate or return on investment) * A multi-variable controller, ie., use two or more independent variables to simultaneously reach a specification on the same number of dependent variables * VLE/LLE regression by the maximum-likelihood method * Tweak VLE to match plant column results * Do equipment sizing and costing (allowing user's cost corrrelations) and capital costing * A distillation program (Newton) with very flexible specifications * A sensitivity anaylsis with more than one independent variable The key is that the software must be CHEAP and preferably free. Productivity does not seem to be a concern anymore. Any references will be appreciated! Mark J. Potter, P.E.Return to Top
