Electrical Impulses Intrigue Nahman
How can one measure the speed of electrical impulses in such machines as digital computers, speeds which react in thousandths of a second or even less?
The study of electrical impulses and high speed digital systems has intrigued Norris Nahman, professor of electrical engineering, for some time.
Prof. Nahman, along with his coworkers Harvey Doemland and Robert Kulterman, assistant professors of electrical engineering, has been supervising study of the measurement of electrical impulses at the KU Electronics Research Laboratory.
PROF. NAHMAN said the laboratory has received support from many sources, including the Department of Defense, since January, 1956.
That was the year the Electronics Laboratory was built southwest of 15th and Iowa streets. The laboratory is permanently staffed by electrical engineering department professors who are assisted parttime by graduate and undergraduate students.
The total amount of external research support which the laboratory has received since its beginning is $734,205.
Prof. Nahman said he has been interested in high speed digital systems for many years. This led him
Awards Announced For Asia Institute
Seven students from four schools have been awarded National Defense Foreign Language Undergraduate Fellowships to attend the KU Summer Chinese and Japanese Institute June 10-Aug. 16.
Announcement of the United States Office of Education grants was made today by Thomas R. Smith, professor of geography, and director of the KU Center for East Asian Studies.
The three KU students recommended by the KU selection committee to the Office of Education in the national competition received fellowships. They are Sharon L. Briggs, Fort Leavenworth junior; Richard A. Lawson, Wichita junior; and Patricia E. Leonard, Tulaa, Okla., freshman.
FELLOWSHIPS were also awarded to Susan B. Rifkin and John Schoonbeek of Colorado University; Emma E. Tao of Washington University, St. Louis, and Adrian Akmaniain of the University of Arizona.
Eesides the undergraduate awards. Jack Salmon, Elkhart graduate student, received a National Defense Education Act Title VI fellowship. It will enable him to study Japanese at the institute.
An NDEA contract of $14,000, plus matching funds from KU, will finance the summer program, a cooperative venture with the University of Colorado.
Besides the newly announced awards, additional scholarship money from private sources has been made available. Prof. Smith said. It will be awarded on the basis of merit and need by the KU selection committee.
"This is an excellent opportunity for a student to begin serious study of Japanese or Chinese," Prof. Smith said. "We will consider applications from persons at all levels from high school seniors on up."

to the study of the measurement of electrical impulses.
HE EXPLAINED that systems such as digital computers are being designed to run faster and faster. For these machines it is necessary to have components that react rapidly.
The electrical pulses which Prof. Nahman and his associates principally study have a time duration of less than a billionth of a second (nanosecond).
Through a pulse comparison system, Prof. Nahman has been able to measure time down to one thousandth of a nanosecond (pico second). In the pulse comparison system, the electrical pulse is divided into two channels and the two parts are compared to each other through coincidence studies.
THE RESULT of the method is that certain time characteristics of the original pulse are resolved down to picosecond increments.
Another area in which the measurement of electrical impulses is valuable is in long range radar. Prof. Nahman explained that long-distance radar is very useful in military and scientific systems. For example, in space exploration a lot of power is needed to generate the required radar pulses.
The pulses of energy are sent out into space. When they strike an object, a portion of the energy returns in the form of the reflected signal. The further out the radar is sent, said Prof. Nahman, the more energy is needed.
THE PROBLEM is how to pack a lot of energy into a short period of time. Prof. Nahman explained that nanosecond pulse techniques are useful in solving this problem.
Radar makes use of electro-magnetic waves which travel at the speed of light, Prof. Nahman said. Light in free space travels 30 centimeters in a nanosecond. He explained that accurate timing techniques are necessary for high accuracy in long-distance radar.
TV Party Planned For Tomorrow Night
A TV Party will be held during the telecast of "The Invincible Mr. Disraeli" tomorrow night.
The party, sponsored by Student Union Activities, will be at 7:30 p.m. in the south lounge of the Kansas Union.
The television program features Trevor Howard and Greer Garson.
Aldon Bell, assistant professor of history, will discuss the program afterwards.
An Exchange Visitors Committee composed of four KU faculty members, under the direction of the U.S. State Department, has been organized at KU.
Committee To Aid Foreign Students
The committee members are James K. Hitt, registrar; John H. Nelson, dean of the Graduate School; J. A. Burzle, professor of German and chairman of Foreign Students Scholarships Committee, and Clark Coan, foreign student adviser.

Those under the supervision of the committee are foreign students on KU scholarships, on U.S. government grants, on assistantship and foreign faculty and staff members.
The primary purpose of the committee is to supervise all its members. The committee keeps records of its members' progress, reviews the financial positions of its members, and considers the applications of its members for employment.
The problems or questions of any member are forwarded to the committee by Coan.
Foreign students and faculty and staff members under this program are on J-1 stay visa.
The committee is completely free from the supervision of the U.S. Immigration and Naturalization Service.

Law Student Receives Award
Robert L. Driscoll, Lawrence second year law student, has been named to receive the Rocky Mountain Mineral Law Foundation $200 scholarship.
The award was based on scholarship and academic work done in studies of oil and gas, including the writing of an article on mineral law. Driscoll's article, "Condemnation for Underground Storage of Natural Gas," appeared in the most recent issue of the Kansas Law Review.
