The United States military continues to have difficulty maintaining the number of troops they need to accomplish their global military missions. The United States military medical service has been struggling with methods of identifying mental disorders, including schizophrenia, during recruitment and, if possible, no later than basic training. From World War I, the United States military medica...

Novel frequency doubler circuits and dividers for clock signal generation are presented. In combination with two edge detectors and two duty cycle control buffers a low cost frequency doubler circuit is achieved as compared to Phase-Locked Loop (PLL) design. An input clock signal with an unpredictable duty cycle is inputted to a rising (or falling) edge detector. The edge detector converts the ...

19 ABSTRACT {Continue on reverse if necessary and identify by block number) This report is the seventh in a series that examines officer career development. Two unrestricted line (URL) officer communities were examined: aviation (AWOs) and surface (SWOs). The purpose of this research was to use the contrasting impressions that URL officers have among joint-duty shore, Navy shore, and Navy sea d...

A simple odd number frequency divider with 50% duty cycle is presented. The odd number frequency divider consists of a general odd number counter and the proposed duty cycle trimming circuit. The duty cycle trimming circuit can output 50% duty cycle with only additional six transistors. A prototype divide-by-5 circuit with 50% duty cycle was implemented for a 500-Mb/s ∼ 5.6-Gb/s 1:10 CDR/DEMUX ...

Remembering the coronavirus pandemic represents an obligation to present and future. Illuminating intersections between remembrance, documentary heritage, memory institutions COVID-19, this article argues that libraries, archives museums have a unique urgent duty document as it unfolds help ensure its associated recorded heritage is collected, preserved archived for future purposes of consultat...

Nitriding is a surface treatment technique used to introduce nitrogen into metallic materials to improve their surface hardness, mechanical properties, wear resistance and corrosion resistance. In this research, the effects of plasma nitriding parameters including frequency and duty cycle were investigated on samples with different grooves dimensions. Steel blocks prepared from DIN1.2344 hot wo...
