This manual provides guidance on Noncommissioned Officer professional development programs for each of the Army’s military occupational specialties. It applies to the active ARMY, the Army National Guard/Army National Guard of the UnitedStates, and the U.S. Army.

Algorithmic Information Theory.pdf

Taken from Foreword: Turing’s deep 1937 paper made it clear that G¨odel’s astonishing earlier
results on arithmetic undecidability related in a very natural way to a class of computing automata, nonexistent at the time of Turing’s paper, but destined to appear only a few years later, subsequently to proliferate as the ubiquitous stored-program computer of today. The appearance of computers, and the involvement of a large scienti c community in elucidation of their properties and limitations, greatly enriched the line of thought opened by Turing. Turing’s distinction between computational problems was rawly binary: some were solvable by algorithms, others not. Later work, of which an attractive part is elegantly developed in the present volume, re ned this into a multiplicity of scales of computational difficulty, which is still developing as a fundamental theory of information and computation that plays much the same role in computer science that classical thermodynamics plays in physics: by de ning the outer limits of the possible, it prevents designers of algorithms from trying to create computational structures which provably do not exist. It is not surprising that such a thermodynamics of information should be as rich in philosophical consequence as thermodynamics itself.

Bridge Detailing Manual.pdf

Taken from definitions:
bridge - A bridge is a single span structure of over 20 feet, measured from face to face of
abutments, or multiple span structures of over 20 feet (including multiple box culverts,
measured between inside of end walls along the centerline of structure). Batteries of pipe
culverts, regardless of their length, are not bridges.
culverts - Culverts are those drainage structures not defined as bridges
highway underpass - A highway underpass is a grade separation where the subject (funding) highway passes under an intersecting highway (also called a Highway Undercrossing)
highway overpass - A highway overpass is a grade separation where the subject (funding) highway passes over an intersecting highway (also called a Highway Overcrossing)
railroad underpass - A railroad underpass is a grade separation where a highway passes
under an intersecting railroad (also called a Railroad Undercrossing)
railroad overpass - A railroad overpass is a grade separation where a highway passes over an intersecting railroad (also called a Railroad Overcrossing)
pedestrian underpass - A pedestrian underpass is a grade separation where a highway passes under an intersecting pedestrian walkway
stream crossing - A stream crossing is a location where the subject highway passes over an
intersecting waterway

Bridge Design Manual - LRFD.pdf

Taken from Implementation: Load and Resistance Factor Design (LRFD) is a design methodology that makes use of load and resistance factors based on the known variability of applied loads and material properties. In 1994, the American Association of State Highway and Transportation Officials (AASHTO) published the first AASHTO Load and Resistance Factor Bridge Design Specifications. The Federal Highway Administration (FHWA) has mandated the use of LRFD for all bridges for which the Texas Department of Transportation (TxDOT) initiates preliminary engineering after October 2007.
