Some Results On The Distance Properties Of Convolutional Codes, Luther D. Rudolph, Alexander Miczo

Electrical Engineering and Computer Science - Technical Reports

Rate 1/2 binary convolutional codes are analyzed and a lower bound on free distance in terms of the minimum distances of two associated cyclic codes ìs derived. Next, the complexity of computing the free distance is discussed and a counterexample to a conjecture on the relationship of row distance to free distance for systematic codes Ìs presented. Finally, an improved Gilbert bound for definite decoding is derived.

Nonbiolog1cal Alteration Of 3-Chloro P-Toluidine Hydrochloride (Drc-1339) In An Aqueous Solution, T. R. Darden, Robert G. Schwab

Bird Control Seminars Proceedings

The effectiveness of 3-chloro p-toluidine (DRC-1339) as an avicide, particular¬ly on the European starling, has been adequately demonstrated (DeCino, Cunningham, and Schafer, 1966; Schwab, 1965, 1966, and 1967). Methods of applying the com¬pound which have proved useful range from the standard baiting technique (Besser, Royall, and DeGrazio, 1967; Royall, DeCino, and Besser, 1967; West, 1968) to pos¬sible aerial application of the compound to roosting sites (Schwab, 1967). These methods, particularly the latter, inherently lead to widespread environmental exposure. As the chemical name implies, DRC-1339 is a chlorinated hydrocarbon. It thereby carries the stigma, whether justifiable or not, of environmental persistence …

Sonic Systems For Controlling Bird Depredations, William D. Fitzwater

Bird Control Seminars Proceedings

The sounds used in controlling bird depredations can be classified into three types:

(1) AUDIBLE DISTURBING NOISES: From clapping of hands by primitive peoples to the modern exploding shotgun shells, loud noises have long been used to frighten birds from man's crops. They are still a valuable supplement to other methods or when needed for short, discontinuous periods.

(2) ULTRASONICS: Sounds over 20,000 cps are apparently beyond the limit of birds as well as humans. There is no effective use of ultrasonics in bird control as yet.

(3) BIOSONICS: While song is a more noticeable facet of bird communication, the …

The Dickcissel: A Problem In Ripening Grains In Latin America, Jerome F. Besser, John W. De Grazio, Kenneth H. Larsen

Bird Control Seminars Proceedings

Bird damage to crops in Latin America--from Mexico to Venezuela and Colom¬bia-is chiefly caused by fringillids, icterids, and psittids (De Grazio and Besser, 1970). Damage to grains such as rice and grain sorghum by various fringillids-sometimes re¬ferred to as "chisguas" by local landowners-is especially troublesome. The fringillid most often implicated in major problems is the dickcissel (Spiza americana).

Dickcissels are not known to cause serious damage problems within their breed¬ing range, which is chiefly the prairies and hay meadows of the central United States. In August, small postbreeding flocks congregate, and by September and October these coalesce into much larger …

The Chemical Senses Of Birds, Morley R. Kare

Bird Control Seminars Proceedings

Birds are not concerned with the odors of their immediate environment. To a chicken, a starling or a cowbird, the odors of its environment are of little or no con-sequence. I am not saying that birds do not have the apparatus for olfaction, nor am I saying that no bird can smell. The kiwi of New Zealand is almost totally blind and does sniff. They do have "nostrils" on the tip of the bill. However, they are an unusual exception. If we place highly odoriferous material under one of two food choices and present them to domestic chickens or starlings, …

Bird Hazards To Aircraft, Victor E. F. Solmon

Bird Control Seminars Proceedings

When I spoke to the third Bird Control Seminar in 1966 on "Ecological Control of Bird Hazards to Aircraft", I reviewed what we had accomplished up to that time. I spoke about the extent of the problem, the bird species involved and the methods we used to make the airports less attractive to birds that created hazards to aircraft.

I wish to discuss today our accomplishments since 1966. I have presented a number of papers on the topic including one with Dr. W. W. H. Gunn, in 1967 at a meeting in the United Kingdom, and others in the United …

Investigation Of The Alpha-Sub-Gamma Phase In Alnico 6, Cortez Samuel

Dissertations and Theses

The purpose of this research project was to study the αᵧ phase in Alnico 6. Other phases were studies for comparison. Also the effect of an applied magnetic field on the formation of the αᵧ phase was investigated.

Three single crystals of Alnico 6 were heat treated for one hour--one at 1250°C, one at 1000°C, and one at 800°C--and water-quenched. The microstructure of each sample was observed with the optical microscope, and X-ray diffraction patterns were taken to determine the crystal structure of the phases present.

Several single crystal samples of Alnico 6 were heat treated at 1000°C and furnace-cooled. …

Grain Size Reconnaissance Of The Virginia-North Carolina Inner Shelf Analysis By Settling Technique, Robert Bailey Sanford Jr.

OES Theses and Dissertations

The 2-fold purpose of this study is to calibrate a Rapid Sediment Analyzer and to use it to aid in the determination of the genesis of sediment on the inner continental shelf between Cape Henry and Cape Hatteras. Rapid Sediment Analyzer calibration was conducted by comparison of sieving and settling results of similar sands.

The study area was divided into sediment provinces by both a qualitative procedure (grain size and topography) and a quantitatively procedure (factor-vector analysis). Qualitative provinces are beach and surf, upper shore face, lower shore face, sea floor, and terminal shoals. The berm fines from each terminal …

The Effects Of A Twelve Mile Limit For The Territorial Sea, Richard J. Brennan

Marine Affairs Theses and Major Papers

A treaty setting the limit of territorial waters at twelve miles will probably be negotiated and accepted by most nations in the near future. In areas not involving straits, this limit will have both beneficial and harmful effects, but it appears to be the best solution that can be achieved. However, in order to ensure that confidence in the free use of the oceans is maintained, the United States should attempt to have included in the treaty a provision for a channel of high seas through international straits. Agreement to such a provision will be difficult to obtain and if …

The Historic End Of Closed Seas, James Edward Grise

Marine Affairs Theses and Major Papers

The purpose of this paper is to consider the rather vague claims to closed seas by the Soviet Union and to determine what direction these claims are taking. The first part of the paper deals with the history and development of the closed seas concept and expands it into the present day claims in this area. It attempts to show how some of the past claims have remained over the years and how some of the others have progressed to claims of historic waters. In the final section an attempt is made to show some method for resolving some of …

An Analysis Of Orthodontic Treatment Results Employing Class Ii Armstrong Adjustable Intermaxillary Springs, Michael E. Shumate

Loma Linda University Electronic Theses, Dissertations & Projects

A study of orthodontic treatment results employing Class II Armstrong Adjustable Intermaxillary Springs was made on twenty-eight randomly selected patients which were treated by Dr. Maclay Armstrong.

The skeletal and dental changes observed during treatment with the Class II springs was compared with those results observed when comparable type malocclusions were treated with Class II elastics. A list of changes which were observed during treatment with Class II elastics was compiled from the literature using individual studies published by Ricketts, Creekmore and Hanes.

The study was based on the findings observed in the initial and final cephalometric radiographs. A statistical …

This quadrangle is located in the central part of northern Utah about 8.6 miles south of the Utah-Idaho State Line. The Bear River Range, along the eastern margin of the quadrangle, consists of stratigraphic units ranging in age from Precambrian to Devonian. The Salt Lake Formation of Tertiary age rests unconformably on Precambrian quartzite and Paleozoic units along the western side of the range. The Lake Bonneville Group overlaps Cambrian rocks in the southern part of the area and overlaps the Salt Lake Formation in the northern part. …

The Ontogeny Of Social Behavior Of Uinta Ground Squirrels, D. Andrew Saunders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The social behavior of juvenile Uinta ground squirrels (Spermophilus armatus) was studied for 2 1/2 years in northeastern Utah. The purpose of the study was to describe the developing social behavior of unconfined, marked squirrels. Their behavior was recorded with motion pictures and written descriptions from the time they emerged from the natal burrow until they entered hibernation.

Three phases of behavioral development were apparent. The first phase began when the juveniles appeared above ground and ended 5 weeks later. This was a period of socialization and consisted of behavioral patterns best described as play. The second phase …

A Fortran List Processor (Flip), Karl A. Fugal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A series of Basic Assembler Language subroutines were developed and made available to the FORTRAN IV language processor which makes list processing possible in a flexible and easily understood way.

The subroutine will create and maintain list structures in the computer's core storage. The subroutines are sufficiently general to permit FORTRAN programmers to tailor list processing routines to their own individual requirements. List structure sizes are limited only by the amount of core storage available.

Recommendations For A United States Position Regarding Delimitation Of The Outer Boundary Of The "Legal" Continental Shelves, Brian K. Hannula

Marine Affairs Theses and Major Papers

The Convention on the Continental Shelf has come under attack because it does not establish a precise outer boundary for the "legal" continental shelf. It is the author's opinion that the United States should propose or support a revision of the Convention which would rectify this situation. A suitable delimitation proposal must have considerable domestic support and should represent the best compromise between opposing domestic views. A proposed revision of the Convention must, also, have strong international support if it is to be adopted. Each nation will determine a preferred delimitation which depends on the configuration of its own continental …
