Review of Feedback Systems
CHAPTER 1 Review of Feedback Systems Marc Thompson Dr. Marc Thompson leads us to an appreciation of how the world has learned about FEEDBACK (negative) over the years, so we can understand how to do better feedback in our systems. /rap Introduction and Some Early History of Feedback Control A feedback system is one that compares its output to a desired input and takes corrective action to force the output to follow the input. Arguably, the beginnings of automatic feedback control 1 can be traced back to the work of James Watt in the 1700s. Watt did lots of work on steam engines, and he adapted 2 a centrifugal governor to automatically control the speed of a steam engine. The governor comprised two rotating metal balls that would fl y out due to centrifugal force. The amount of “ fl y-out ” was then used to regulate the speed of the steam engine by adjusting a throttle. This was an example of proportional control. The steam engines of Watt ’ s day worked well with the governor, but as steam engines became larger and better engineered, it was found that there could be stability problems in the engine speed. One of the problems was hunting , or an engine speed that would surge and decrease, apparently hunting for a stable operating point. This phenomenon was not well understood until the latter part of the 19th century, when James Maxwell 3 (yes, the same Maxwell famous for all those equations) developed the mathematics of the stability of the Watt governor using differential equations. 1 Others may argue that the origins of feedback control trace back to the water clocks and fl oat regulators of the ancients. -
Leonard M. Rieser '44 Provost and Dean of the Faculty Emeritus
Leonard M. Rieser ’44 Provost and Dean of the Faculty Emeritus An Interview Conducted by Jane Carroll Hanover, NH August 15 and 28, and October 22, 1996 Phonotape Nos. 1176 R547/1–5 Special Collections Dartmouth College Hanover, New Hampshire Leonard Rieser Interview INTERVIEW: Leonard Rieser INTERVIEWED BY: Jane Carroll PLACE: Leonard Rieser’s office Hanover, NH DATE: August 16, 1996 CARROLL: Today is the 16th of August 1996, and I’m speaking with former Provost and Dean of the Faculty Leonard Rieser here in his office in Hanover, New Hampshire. I was curious when you first came to Dartmouth. That was 1940? RIESER: As an undergraduate. CARROLL: As an undergraduate. How did you choose Dartmouth? RIESER: Your question’s very perceptive, as you’ll see from your answer. It was certainly my intention to go to Harvard, and my family’s intention; and as late as July of 1940 I was sitting at the camp where I was a counselor, talking to a friend with whom I planned to room in freshman dorms. We were picking a room. And I had a phone call from my home that a telegram had come saying something about “Harvard is sorry, but your score on your recent English exam meant that you would have to wait a year to come to Harvard.” That set in motion a search for an alternative. In retrospect, I’m surprised that I wasn’t more discouraged by that, or depressed, but it’s because I really hadn’t thought much about alternatives. I may have, earlier, applied to Reed College, I don’t remember, or whether I did it then. -
Ernest Fox Nichols
NATIONAL ACADEMY OF SCIENCES E R N E S T F O X N ICHOLS 1869—1924 A Biographical Memoir by E . L . NICHOLS Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1929 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. ERNEST FOX NICHOLS BY R. L. NICHOLS One winter evening in the year 1885 the present writer lec- tured at the Kansas Agricultural College. It was an illustrated talk on experimental physics to students who thronged the col- lege chapel. Some three years later, when that event had passed into the realm of things half forgotten, two young men appeared at the physical laboratory of Cornell University. They ex- plained that they had been in the audience at Manhattan on the occasion just mentioned and had been so strongly interested that they had decided then and there to devote themselves to the study of physics. Now, having finished their undergrad- uate course they had come east to enter our graduate school. One of these two Kansas boys, both of whom were then quite unknown to the writer, was Ernest Fox Nichols. Nichols was born in Leavenworth, Kansas, on June 1. 1869. He was soon left parentless, a lonely boy but with means to help him obtain an education, and went to live with an uncle and aunt, Mr. and Mrs. Fox, of Manhattan, in that State. He was tall, fair, clear-eyed, of open countenance and winning smile, and there was that about him which once seen was never forgotten. -

Prodigal Genius BIOGRAPHY of NIKOLA TESLA 1994 Brotherhood of Life, Inc., 110 Dartmouth, SE, Albuquerque, New Mexico 87106 USA
Prodigal Genius BIOGRAPHY OF NIKOLA TESLA 1994 Brotherhood of Life, Inc., 110 Dartmouth, SE, Albuquerque, New Mexico 87106 USA "SPECTACULAR" is a mild word for describing the strange experiment with life that comprises the story of Nikola Tesla, and "amazing" fails to do adequate justice to the results that burst from his experiences like an exploding rocket. It is the story of the dazzling scintillations of a superman who created a new world; it is a story that condemns woman as an anchor of the flesh which retards the development of man and limits his accomplishment--and, paradoxically, proves that even the most successful life, if it does not include a woman, is a dismal failure. Even the gods of old, in the wildest imaginings of their worshipers, never undertook such gigantic tasks of world- wide dimension as those which Tesla attempted and accomplished. On the basis of his hopes, his dreams, and his achievements he rated the status of the Olympian gods, and the Greeks would have so enshrined him. Little is the wonder that so-called practical men, with their noses stuck in profit-and-loss statements, did not understand him and thought him strange. The light of human progress is not a dim glow that gradually becomes more luminous with time. The panorama of human evolution is illumined by sudden bursts of dazzling brilliance in intellectual accomplishments that throw their beams far ahead to give us a glimpse of the distant future, that we may more correctly guide our wavering steps today. Tesla, by virtue of the amazing discoveries and inventions which he showered on the world, becomes one of the most resplendent flashes that has ever brightened the scroll of human advancement. -

July 2019 Newsletter GEARS Founded August 13, 1939 News
July 2019 Newsletter GEARS Founded August 13, 1939 News Field day was a success. This year GARS joined us out at the Masonic Lodge. The weather was very comfortable for a change. While band conditions were difficult at first, they improved by the morning. We haven’t totaled the points yet, however it seems that we did better than last year. We also got coverage from Action News and the Chico Enterprise Record. See photos below. My house was struck by lighting on May 30th, hitting my antenna and traveling down the feed line, through the radios and discharged into the house wiring. Fortunately the fire department put out the fire quickly and minimized damage. I’m off the air until repairs are completed to the house. See photo below. The GEARS/GARS new repeater project is proceeding along. The equipment has been ordered. We are waiting for approval from the US Forest Service before we can begin installation. At our next GEARS meeting Kevin Fullerton WB7SKS will be talking about emergency operations for the Camp Fire. He has some very interesting experiences to tell us about, and suggestions for preparing for emergencies. The Steak Bake is Sep.7th at Wildwood picnic area in Chico at 3:30pm - 7pm. This month our feature article is about Sir John Ambrose Fleming’s invention of the vacuum tube. ‘73 Join GEARS on Facebook Jim Matthews K6EST www.facebook.com For timely [email protected] news and additional information. 530-893-3314 July 2019 Calendar Sun Mon Tue Wed Thu Fri Sat 1 2 3 4 5 6 7pm GARS Net 7:30pm GEARS Net 7pm Simplex Net 8pm
