The Super-Regenerative Receiver invented by Edwin Armstrong in 1922 provides simple but effective reception and amplification of modulated radio signals. Despite its age and the increased complexity of communication systems over the years, Super-Regenerative Receivers still find use in various specialized applications due to the simplicity and low-power consumption of the design.

The purposes of this work were to: 1. Find an analytical correlation between the transverse distributions of longitudinal transverse distributions of longitudinal bending moments nad the cross-sectional deflections in box-beam bridges. 2. Develop a practical method for the estimation of bending moments in box-beam bridges by the use of cross-sectional deflections.

This thesis analyses the sequential production process. It reviews and comments on the work that has been done in this area

The processing of the tungsten heavy alloys powders, 93%W – 5.6%Ni – 1.4%Fe (wt%), provided by Global Tungsten and Powder Corp. (GTP) was investigated by using selective laser melting (SLM) additive manufacturing method. Due to the refractory character of

Louisine Waldron Elder Havemeyer's personal evolution from an elite, reserved, art-collecting wife of an American Gilded Age industrialist to an engaged, unapologetically outspoken activist on behalf of all women's right to vote is emblematic of the myriad ways women moved out into the world from their domestic spheres in the early twentieth century, harnessing the increasing power of collective visual protest as a peaceful, non-violent tactic to demand justice and a voice.Her 1915 suffrage exhibit held at the Knoedler Gallery in New York City may be a modest moment of microhistory in the l

Internally precracked thick-walled cylinders were fractured under uniaxial stress conditions both without and with internal pressure to determine the difference in fracture characteristics. The complex loading and interaction with the pressuring media are possible factors to explain the subcritical crack growth.

An analog system is described for automatically plotting of the trajectories of free electrons in a bidimensional electrostatic field using the conductive sheet model.

This paper is a report of some work of Professor Rudolf Fueter on functions of a hypercomplex variable, presented at the University of Zurich in 1948-1949, and reproduced by the Argonne National Laboratory.
