Producer Gas, Edward P. Dwyer Jan 1895

Producer Gas, Edward P. Dwyer

Bachelors Theses

"Producer gas, so named owing to being produced in special forms of apparatus known as Producers. The fuel is decomposed into combustible gases, whereby most of the C is burnt to CO, whilst the H either remains free, or is converted into carburretted Hydrogen. Directly above the grate carbonic anhydride is formed but thus is rapidly converted into carbonic oxide; reaction as follows: CO₂ + C = 2CO.

Amongst these heavy carburetted hydrogen (C₂H₄) is that which principally increases the value of the gas as fuel and the drier the fuel used the more of the gas is produced. A …


Imaginary Functions, Floyd Davis Dec 1881

Imaginary Functions, Floyd Davis

Bachelors Theses

"The imaginary expression which occurs in common Algebra, and in all the higher departments of mathematical science, has been one of the most perplexing problems which the human mind has encountered in any age. It was studied by the early mathematicians and became a field of speculation, but developed no marked results, for it was generally considered algebraically and in the interpretation is a symbol of an impossible operation. But many of the problems arising from algebraic-geometrical analysis involving imaginaries was of such importance to mathematical and physical science that great attempts were made to establish their solution. It was …


Iron Bridges, Lindsay Coppedge Dec 1877

Iron Bridges, Lindsay Coppedge

Bachelors Theses

"The superiority of iron over wood as the material for bridges is now generally understood that we see no need of any discussion"--page 3.


Maramec Bridge, Thomas H. Millsaps Dec 1876

Maramec Bridge, Thomas H. Millsaps

Professional Degree Theses

"Bridge-building, as a science, is comparatively of recent date, for relating to now, of what may be called ancient bridges, do we read of them having been mathematical calculations, determining the strains upon the constituent parts of the bridge structure. This very necessary operation seems to have been entirely omitted. This was, probably, because to that time, there had been no thoroughly scientific investigation, of the new and beautiful subject of scientific bridge-building. At the present time, we determine with a minuteness the strain thrown upon any part of a bridge. We are thus enabled to give the proper dimensions …
