The David W. Fentress Family Letters, 1856-1969
Transcript of a letter by an unidentified author to David Fentress regarding sharing federal newspapers and the banning of federal newspapers in some areas. The author passes on the news of the war including the destruction of the Federal merchantmen by the Confederate fleet. He passes along world news: Russia preparing to go to War with Europe and how that could negatively affect the Confederacy. There is also speculation on the future of the war

David Zimmer Christmas letter
This Christmas letter written November 30, 1999, by David Zimmer is titled "Season's Greetings from the last of the Red-Hot-Santas!" It features an illustration of Santa Claus with a guitar, and a summary of Zimmer's year.
David Zimmer (1929-2005) was born in Harrisburg, Ohio. He enlisted in the U.S. Army and served for two years during the Korean War at the Brooke Army Medical Center in San Antonio, where he performed in drag for wounded soldiers. After the war, he returned to Ohio. Zimmer performed as Dolly Divine, a name inspired by the song "Hello Dolly." In 1964, he established the Berwick Ball with Orn Huntington, another important early gay activist in Central Ohio. The Ball began as a formal Halloween costume ball that provided a safe space to gather and enjoy drag shows for the gay community each year; over the years, it grew into an annual Halloween tradition and an important fundraiser for the AIDS movement and other charities. During the 1970s, Zimmer was also known for hosting lavish parties at his Harrisburg home. In 1989, he moved to the German Village area of Columbus where he remained active in the community. During the 1990s, Zimmer continued to perform in and out of drag and commissioned costume designer Dick Frank to make elaborate outfits. Zimmer worked for Huntington National Bank for 39 years and was a member of the Harrisburg United Methodist Church, Veterans of Foreign Wars and the German Village Society

Towards a Coordinated Spectral Support Estimation of Sinusoidal Disturbances in Smart Grids through Synchronized Measurements
Implementation of phasor measurement units on low-cost embedded platforms: A feasibility study
The Phasor Measurement Units (PMUs) are currently considered among the most useful instruments for smart grid monitoring. While the traditional PMUs deployed at the transmission level are usually high-performance and expensive instruments, the interest in smaller and cheaper units able to perform synchronized measurements of voltage and current waveforms at the distribution level is currently growing. In this paper, a feasibility study about the implementation of state-of-the-art estimation algorithms for PMUs in low-cost embedded platforms is presented. The proposed approach relies on an Interpolated Discrete Fourier Transform (IpDFT) for static frequency offset estimation followed by a modified Taylor-Fourier Transform (TFT) for waveform amplitude, phase, frequency and rate of change of frequency (ROCOF) estimation under dynamic conditions. Both algorithms, implemented in C++, run on a Beagle-Bone Black board. After evaluating the total computation time as a function of both the sampling rate and the number of observed cycles, a criterion to choose the data acquisition stage is described. Finally, the accuracy of synchrophasor, frequency and ROCOF estimators is determined by emulating most of the testing conditions reported in the IEEE Standards C37.118.1-2011 and C37.118.1a-2014
