This book reports on the 13th International Workshop on Railway Noise (IWRN13), held on September 16-20, 2019, in Ghent, Belgium. It gathers original peer-reviewed papers describing the latest developments in railway noise and vibration, as well as state-of-the-art reviews written by authoritative experts in the field. The different papers cover a broad range of railway noise and vibration topics, such as rolling noise, wheel squeal, noise perception, prediction methods, measurements and monitoring, and vehicle interior noise. Further topics include rail roughness, rail corrugation and grinding, high-speed rail and aerodynamic noise, structure-borne noise, ground-borne noise and vibration, and resilient track forms. Policy, criteria and regulation are also discussed. Offering extensive and timely information to both scientists and engineers, this book will help them in their daily efforts to identify, understand and solve problems related to railway noise and vibration, and to achieve the ultimate goal of reducing the environmental impact of railway systems.

The Energetic Gamma-Ray Experiment Telescope (EGRET) instru ment on the Compton Gamma-Ray Observatory left as a legacy its Third Catalog of High Energy Gamma-Ray Sources, whose detections include a large number of blazars, some pulsars, the Large Magellanic Cloud and a solar flare. Most of the newly discovered objects - a majority of the catalog -are unidentified sources, with a clearly predominant Galactic population. Are all these radio-quiet pulsars, like Geminga, or is there a novel type of celestial object, awaiting identification? In spite of the limited angular resolution provided by EGRET and COMPTEL, there is still much to learn about unidentified ,-ray sources: correlation studies, multiwavelength observations and theoretical work can provide valuable clues, specially if these efforts are carried out in a coordinated manner. The aim of this workshop, held from October 9 to 11, 2000, at the Instituto N acional de Astrofisica, Optica y Electronica, at Tonantzintla, Mexico, was to gather experts on the subject, including observational as tronomers specialized in other regions of the electromagnetic spectrum, in an effort to address the question of the Nature of Galactic high-energy gamma-ray sources, both from the theoretical and observational perspec tive, and elaborate schemes for future identification studies which can make use of existing and forthcoming facilities.

This the sequel to "Baker's Dozen: a Fantasy Novel," my first book of dark fantasy. In it, the remainder of our heroes and heroines, with the help of powerful allies, face a new enemy and a world that is getting more dangerous by the day. There are elements of both epic and contemporary fantasy plus occult and horror. Also included is a collection of mixed-genre fiction and articles called "My Shorts."

In October 1956, Mao Tse-tung ordered the start of China's space program. Four years later, on 5 November 1960, China launched its first rocket, becoming the fourth country, behind Germany, the United States, and the Soviet Union, to enter space. Today China routinely launches space satellites for Western companies, including US corporations, and is increasing its share of the global space launch market. But the Chinese also use the technology and assistance gained in foreign ventures for PRC military applications. And a principal organization in China's space effort, the China Great Wall Industry Corporation, has been identified by the US State Department as engaging in missile technology proliferation activities. How does China's space effort fit into its overall development strategy? What is China doing in military space applications? These are the two principal questions addressed, in order, by Lt Col William R. Morris and Col David J. Thompson, both of whom traveled to the PRC in the spring of 2001. Lt Col Morris examines the relationship between China's evolving space effort and its national development goals. He shows how the Chinese have used their space launches both for fund raising and employment activities, and as a foreign policy tool: Beijing now has space-related technical and economic cooperation with over 70 countries. But the Chinese also use spin-offs and pirated technologies from space operations to enhance their imagery, signals, and communications intelligence. The author also speculates that the Chinese may be developing electronic pulse weapons and lazer dazzlers that could degrade an adversary's satellites. Col Thompson, in his concentrated focus on China's military space applications, examines PRC ground, space, counterspace, and space policy aspects. His principal findings: China has plans to construct a new launch site in the deep south; PRC telemetry, tracking and command capacities are improving; China has the ability to conduct limited intelligence, surveillance and reconnaissance missions from space; the PRC is pursuing a counterspace capability most likely using satellite jammers and anti-satellites (possibly parasitic or nano-satellites). Col Thompson concludes that while China's space program does not now constitute a global threat, the PRC is pursuing space capabilities that will increase its regional influence, and deny an adversary certain uses of space.

On 8 October 1956, the Central Committee of the Communist Party of China, presided over by Mao Tse-tung, established the Fifth Research Academy of the Ministry of National Defense to develop a space effort. This was the official beginning of the People's Republic of China (PRC) space program. Just four years later, on 5 November 1960, China launched its first rocket becoming the fourth country behind Germany, the United States, and the Soviet Union, to enter space. The Chinese space program has survived periods of traumatic upheaval during its 44-year history. Today, space is the cornerstone of China's national science and technology development effort. Beijing is advancing China's space program on a number of fronts hoping to become a recognized international space power. The Chinese leadership under Jiang Zemin wants China to become a strong, modern, and ultimately wealthy nation, in short a great power. Given its natural resources, manpower, nuclear forces, seat on the UN Security Council, and growing economy, China wants parity with other great powers. To do this Beijing has crafted a national development strategy led by certain sectors. The purpose of this paper is to discuss how China's space program aids the government in reaching for great power.

The Maxwell Papers, the Air War College's occasional papers series, focus on current and future issues of interest to the Air Force and US Department of Defense. The first Maxwell Papers was published in May of 1996 with the Air University Commander's signature on the foreword. Maxwell Papers are open to all interested authors, particularly Air War College faculty and students, but also to other officers and analysts. Maxwell Papers have been distributed to over 400 addresses including all senior Air Force and US Department of Defense decision makers, Professional Military Education (PME) schools, contractors, and other US agencies, and more than 40 foreign air forces and institutions. This document is a Air War College Maxwell Paper.

12 strangers from different realities are kidnapped and left stranded on an Earth were magic has supplanted technology and ancient empires have prospered for many centuries in this work of dark fantasy. Among some are a deadly assassin from the Canadian Armed Forces, a brilliant Irish trauma surgeon, a "nuclear winter" survivor, and a medical marvel whose augmented strength does little to compensate for his irreversible brain damage. Receiving the aid of an ancient wizard of the Ethermen, the group of 12 finds themselves battling fierce creatures and witnessing marvels beyond their imaginations. But their journey becomes more perilous when a necromancer plans to use them in his overthrow of Earth...by plunging their new home into eternal night. Their survival depends on trust...but will their past lives keep them from the one chance they have to find their way home?
