A Traffic Survey Of The City Of Sioux Falls, South Dakota, George Everett Thompson

Electronic Theses and Dissertations

How to control the traffic on the streets of our cities is becoming one of the most important problems of the present day. an urban community depends for its existence upon the transportation facilities both internal and external. The external transportation is necessary for a city's growth because food supplies and raw materials must be brought into the city and the commodities which are produced in the cities must be distributed to other places.


The North Side Sewage Treatment Works Of The Chicago Sanitary District, Floyd Allen Gerard Jan 1930

The North Side Sewage Treatment Works Of The Chicago Sanitary District, Floyd Allen Gerard

Professional Degree Theses

"My aim in writing this thesis has been to give a clear and concise picture of the Plant, its construction, operating experiences, results and the need for sewage treatment. For this reason, I have incorporated much information, which, while not dealing directly with the subject in hand, is closely allied to it and forms a very necessary background. As the Sanitary District considers its actual operating results confidential, I have refrained from including them. Much useful information can be derived from a careful study of the photographs and drawings included"--page ii.

Data For Standard Curve Chord Steel Roof Trusses., William Hewitt Bush

Professional Degree Theses

"In the past the Engineering Department of the structural steel company, by which the writer is employed, has been troubled with having to make a large number of preliminary steel truss designs for the purpose of estimating weights for competitive bids on structural steel building contracts. In order to eliminate this expenditure of time, a study was made of the possibility of making a standard design for curved chord steel roof trusses that would give the desired information by observation"--Truss Design, page 5.


The West Side Sewage Treatment Works Of The Sanitary District Of Chicago, John Edwin Mccauley Jan 1930

The West Side Sewage Treatment Works Of The Sanitary District Of Chicago, John Edwin Mccauley

Professional Degree Theses

"Herein following is a thesis on the West Side Sewage Treatment Works of the Sanitary District of Chicago. I have endeavored to cover a large field in one thesis, but think is giving the material I have, the fundamental points have been covered. The local need of sewage treatment is so involved with county, state, Federal, and even International issues that to write solely of local conditions would be to leave out the main part of the story. So, in writing, I have tried to dover enough of the subject to give the historical facts along with the construction side …


A Study On Concrete Roads, Joaquin H. Hernandez Barreneches Apr 1929

A Study On Concrete Roads, Joaquin H. Hernandez Barreneches

Bachelors’ Theses

There is hardly an institution in existence that is as old and as useful as the road. In fact, it is so old and we are so used to its usefulness that we seldom think of its origin or its history. We take them more or leas for granted.

Drainage And Irrigation Of A Thirty-Six Square Mile Tract Of Land In Louisiana, Ralph Charles Dodge Jan 1928

Drainage And Irrigation Of A Thirty-Six Square Mile Tract Of Land In Louisiana, Ralph Charles Dodge

Bachelors Theses

"Because of the fact that I was unable to secure all of the necessary data concerning the topography of the section in question I made several assumptions. However, these assumptions were not made at random, as the land lies on the coast and is subject to the same conditions as does the southern portion of Jefferson County, Texas, of which I have accurate knowledge and which lies directly across Sabine Pass"--Introduction, page iv.


A Few Notes From The Sanitary Engineering Field, Ronald Davies Ward Jan 1928

A Few Notes From The Sanitary Engineering Field, Ronald Davies Ward

Professional Degree Theses

"This paper, it is felt, may appear to be a somewhat disconnected discussion of a few points that have come to the writer's attention from his limited experience and practice in the field of Sanitary Engineering. It has not been the intention, however, to provide a discussion of continuity which would take the reader from the ground up through the process involved in the design and construction of any particular structure, system, or plant; but rather is it to be considered the writer's attempt - although probably a somewhat feeble one - to set forth in a note-book, as it …


Diversion Of Mississippi Flood Water As Aid To Flood Control, R. W. Campbell Jan 1928

Diversion Of Mississippi Flood Water As Aid To Flood Control, R. W. Campbell

Professional Degree Theses

"For many years the lower Mississippi River valley has been in constant danger from high water causing disastrous floods. The important city of New Orleans, our typical French city, is below the surface of the Mississippi River at all stages, and its only means of protection at present is by a levee. Should this bulkwark give way, the whole of that city would be submerged. With this danger in mind, the writer has undertaken a study for, and design of a spillway above the city to reduce the danger caused by high water. Each year flood heights increase and the …

The Analysis Of Stresses And Design Of Multiple-Arch Dam, Guy Robert Scott Jan 1924

The Analysis Of Stresses And Design Of Multiple-Arch Dam, Guy Robert Scott

Bachelors Theses

"The so-termed: "Multiple", or "Scallop-Arched" dam, as its name implies, is one composed of a series of arches, either semi-circular or segmental in plan. These arches were first vertical but were later inclined downstream, when the engineers recognized the value of the weight of water in increasing the resisting moment. The thrust of these arches, due to the water pressure and the weight of the arch itself, is transmitted directly to the buttresses. There are numerous advantages to this type of dam over that of the gravity type"--Introduction, page 1.

Project For The Construction Of A Standard Gauge Railroad From Guanajay To The Port Of Mariel, P Del R, Royal Sylvester Webster

Professional Degree Theses

"The great industrial development of the Island of Cuba during the period of the World War and the succeeding years, causing the congestion of the existing transportation lines and shipping facilities, has necessitated the opening up of new routes and the providing of additional and better facilities. In the latter part of this period, the decline in the price of sugar, the principal product of the country, has made imperative its more economical production and marketing, which has tended to the opening up of new and cheaper routes to ports of export. In accord with the general activities along this …

Professional Degree Theses

"In taking up the adjustment of survey data on the M.S.M. Campus the first thing to determine [is] the use for said data. The data is used by the Department to determine whether or not the student in his Field Work has pursued correct methods. No attempt is made to require great precision as the student is just learning to use the instruments and time is not allowed in the courses for him to learn other than the rudiments of Surveying"--Part 2, Adjustment Data, Narration of Adjustment Methods, page 24.

Preliminary Study Of Possible Power Development On The Gasconade River, Charles Russell Barnard, Ronald Blair Wills, Harry Wesley Zieseniss Jan 1920

Preliminary Study Of Possible Power Development On The Gasconade River, Charles Russell Barnard, Ronald Blair Wills, Harry Wesley Zieseniss

Bachelors Theses

"The location of a possible dam site on the Gasconade River as a thesis proved to be a very interesting subject. Our first trip pointed out to us that we had undertaken a large task. We also realized that our subject was too big to complete thouroughly sic in the time alloted. Due to this circumstance we tried to cover the essential facts and to eliminate as much of the detail work as possible. For instance, we made no attempt to make a complete survey of the basin, instead, we ran surveys for some distance up the river to give …

Simple Methods And Tables For Determining True Meridian, Howard Jones Teas Jan 1917

Simple Methods And Tables For Determining True Meridian, Howard Jones Teas

Bachelors Theses

"The ordinary methods of determining the true meridian by observation on either Polaris or the sun are so tedious to calculate that most surveyors and students dread making them. Observation on Polaris at either elongation or clumination sic require less calculation and are much simpler, but this simplicity is offset by the fact that they must be taken at an exact instant. If a cloud crosses the sky at the time, the surveyor has to wait until the next night. then again the observer must know the date, exact longitude and latitude and correct time for making the observation, and …


Some Typical Bridges For Logging Railroad Construction, Frederick Hauenstein Jan 1917

Some Typical Bridges For Logging Railroad Construction, Frederick Hauenstein

Professional Degree Theses

"In some of the pine regions of the Ozark Mountains, a considerable portion of the country is rolling and rough, comprising a succession of hills and hollows. The most efficient method of logging such a tract is obtained by locating the logging road so as to secure a down grade haul for the logs, with consequent up grade return for the empty cars. This necessitates locating the main line of the railroad along the principal creek, and then laying spurs up the different tributary creeks as they are met. Such a procedure requires much crossing and re-crossing of creeks and …


A Thesis Submitted To The Faculty Of Marquette University, Lester James Myers Jun 1916

A Thesis Submitted To The Faculty Of Marquette University, Lester James Myers

Bachelors’ Theses

Since the commerce of a country or city determines its position in the world of finance to such a great extent, it is natural to investigate the conditions which govern the country's or city's demand for its share of this commerce, and see if the natural location, and still does not receive its share of the commerce of the country, there is a decided chance for the investigation and removal of the obstacles which are the cause of this condition.


The Design Of A Twelve Story Reinforced Concrete Warehouse, A. M. Fromherz Jun 1916

The Design Of A Twelve Story Reinforced Concrete Warehouse, A. M. Fromherz

Bachelors’ Theses

In submitting this design I do so with the one point in view, namely, to endeavor to determine when reinforced concrete becomes impractical for design purposes.

To produce a maximum condition of loading on the lower floors I have taken up the design of a warehouse which is to carry a live and impact load of 400# per sq. ft., plus the dead load on each of the twelve floors. This condition of loading is not practical for design, but it will produce our desired conditions.

From the design it can be readily seen that the columns become excessive in …

An Investigation Of Blended Cements, Byron Lee Ashdown Jan 1916

An Investigation Of Blended Cements, Byron Lee Ashdown

Bachelors Theses

"It is generally accepted to be a fact that the coarser particles of a cement are practically inert, and that it is only the finest particles that possess the cementing qualities. Exactly what percentage of the whole is active, or possesses the cementing properties, is not known. Since but few experiments pertaining to such have been performed there is consequently little data to be found"--Introduction, page 3.


An Investigation In Concrete, Don H. Morgan Jan 1916

An Investigation In Concrete, Don H. Morgan

Bachelors Theses

"It is the purpose of this investigation to determine the effect of blending a portland cement with a fine silica sand. A blended cement such as this has been used successfully and economically in several important works. The United States Reclamation Service and the Los Angeles Aqueduct commission have made use of such a blended cement in several important structures. This dilution, so to say, of the cement results is a decrease in cost without a loss of strength. In this investigation it has been assured that the cement retained on a #200 sieve is inert and may be replaced …
