Book Description
During the last two centuries BCE, the Western Han capital of Chang'an, near today's Xi'an in northwest China, outshone Augustan Rome in several ways while administering comparable numbers of imperial subjects and equally vast territories. At its grandest, during the last fifty years or so before the collapse of the dynasty in 9 CE, Chang�an boasted imperial libraries with thousands of documents on bamboo and silk in a city nearly three times the size of Rome and nearly four times larger than Alexandria. Many reforms instituted in this capital in ate Western Han substantially shaped not only the institutions of the Eastern Han (25�220 CE) but also the rest of imperial China until 1911. Although thousands of studies document imperial Rome�s glory, until now no book-length work in a Western language has been devoted to Han Chang�an, the reign of Emperor Chengdi (whose accomplishments rival those of Augustus and Hadrian), or the city's impressive library project (26-6 BCE), which ultimately produced the first state-sponsored versions of many of the classics and masterworks that we hold in our hands today. Chang�an 26 BCE addresses this deficiency, using as a focal point the reign of Emperor Chengdi (r. 33�7 bce), specifically the year in which the imperial library project began. This in-depth survey by some of the world�s best scholars, Chinese and Western, explores the built environment, sociopolitical transformations, and leading figures of Chang�an, making a strong case for the revision of historical assumptions about the two Han dynasties. A multidisciplinary volume representing a wealth of scholarly perspectives, the book draws on the established historical record and recent archaeological discoveries of thousands of tombs, building foundations, and remnants of walls and gates from Chang�an and its surrounding area.

Afghanistan 1979–88

Afghanistan 1979–88 PDF Author: Mark Galeotti
Publisher: Bloomsbury Publishing
ISBN: 1472850742
Category : History
Languages : en
Pages : 97

Book Description
The first English-language book to examine the crucial part air power played in the Soviet-Afghan War. The Soviet Union's invasion of Afghanistan was fought as much in the air as on the ground. From the high-level bombing raids that blasted rebel-held mountain valleys, to the Mi-24 helicopter gunships and Su-25 jets that accompanied every substantial army operation, Soviet control of the air was a crucial battlefield asset. Vital to every aspect of its operations, Mi-8 helicopters ferried supplies to remote mountain-top observation points and took the bodies of fallen soldiers on their last journey home in An12 'Black Tulips'. But this was not a wholly one-sided conflict. Even before the Afghan rebels began to acquire man-portable surface-to-air missiles such as the controversial US 'Stinger,' they aggressively and imaginatively adapted. They learnt new techniques of camouflage and deception, set up ambushes against low-level attacks, and even launched daring raids on airbases to destroy aircraft on the ground. Featuring information previously unknown in the West, such as the Soviets' combat-testing of Yak-38 'Forger' naval jump jets, Soviet-expert Mark Galeotti examines the rebel, Kabul government and the Soviet operation in Afghanistan, drawing deeply on Western and Russian sources, and including after-action analyses from the Soviet military. Using maps, battlescenes and detailed 'Bird's Eye Views', he paints a comprehensive picture of the air war and describes how, arguably, it was Soviet air power that made the difference between defeat for Moscow and the subsequent stalemate that they decided to disengage from.

Scattering Characteristics of Aerial and Ground Radar Objects

Scattering Characteristics of Aerial and Ground Radar Objects PDF Author: Oleg I. Sukharevsky
Publisher: CRC Press
ISBN: 1040022723
Category : Technology & Engineering
Languages : en
Pages : 531

Book Description
This book presents computations for various types of aerial and ground objects. It contains a brief explanation of the theoretical calculation methods used for obtaining scattering characteristics of these objects. It provides working examples for the analysis of electromagnetic wave scattering processes by different objects. Scattering Characteristics of Aerial and Ground Radar Objects is divided in two sections. The first section includes scattering characteristics for different aerial objects: aircrafts, helicopters, transport and passenger airplanes, unmanned aerial vehicles, and missiles. The second section contains data about scattering for many ground objects such as tanks, surface-to-air missile systems, ground radars, and other military objects. In total, the book contains actual data for 63 aerial objects (fighters, attack aircraft, bombers, long-range radar detection aircraft, transport aircraft, helicopters, unmanned aerial vehicles, and cruise missiles) and 18 ground objects, among which are anti-aircraft missile systems and tanks. This book contains data obtained by computations such as circular diagrams of radar backscattering; mean and median radar cross section values of various objects; probability distributions of echo signal amplitude given various parameters of illumination and various kinds of underlying surfaces (for ground objects). Also, as an example, the scattering characteristics for one surface ship are given. This book will be a valuable reference for scientists, engineers, and researchers of electromagnetic wave scattering, computational electrodynamics, and those working on radar detection and recognition algorithms for aerial and and ground radar targets.
