Book Summary:

When a great antiquities collector is forced to donate his entire collection to the Hebrew University in Jerusalem, Nili Broshi sees her last chance to finish an archaeological expedition begun decades earlier—a dig that could possibly yield the most important religious artifact in the Middle East. Motivated by the desire to reinstate her father’s legacy as a great archaeologist after he was marginalized by his rival, Nili enlists a ragtag crew—a religious nationalist and his band of hilltop youths, her traitorous brother, and her childhood Palestinian friend, now an archaeological smuggler. As Nili’s father slips deeper into dementia, warring factions close in on and fight over the Ark of the Covenant! Backed by extensive research into this real-world treasure hunt, Rutu Modan sets her affecting novel at the center of a political crisis. She posits that the history of biblical Israel lies in one of the most disputed regions in the world, occupied by Israel and contested by Palestine. Often in direct competition, Palestinians and Israelis dig alongside one another, hoping to find the sacred artifact believed to be a conduit to God. Two-time Eisner Award winner Rutu Modan’s third graphic novel, Tunnels, is her deepest and wildest yet. Potent and funny, Modan reveals the Middle East as no westerner could. Ishai Mishory is a longtime New York City—and newly Bay Area—based translator and sometimes illustrator. He is currently conducting research for a PhD dissertation on 16th century Italian printing.

Book Summary:

A thrilling Cold War narrative of superpower showdowns, media suppression, and two escape tunnels beneath the Berlin Wall. In the summer of 1962, the year after the rise of the Berlin Wall, a group of young West Germans risked prison, Stasi torture, and even death to liberate friends, lovers, and strangers in East Berlin by digging tunnels under the Wall. Then two U.S. television networks heard about the secret projects and raced to be first to document them from the inside. NBC and CBS funded two separate tunnels in return for the right to film the escapes, planning spectacular prime-time specials. President John F. Kennedy, however, was wary of anything that might spark a confrontation with the Soviets, having said, “A wall is better than a war,” and even confessing to Secretary of State Dean Rusk, “We don’t care about East Berlin.” JFK approved unprecedented maneuvers to quash both documentaries, testing the limits of a free press in an era of escalating nuclear tensions. As Greg Mitchell’s riveting narrative unfolds, we meet extraordinary characters: the legendary cyclist who became East Germany’s top target for arrest; the Stasi informer who betrays the “CBS tunnel”; the American student who aided the escapes; an engineer who would later help build the tunnel under the English channel; and the young East Berliner who fled with her baby, then married one of the tunnelers. The Tunnels captures the chilling reach of the Stasi secret police as U.S. networks prepared to “pay for play” but were willing to cave to official pressure, the White House was eager to suppress historic coverage, and ordinary people in dire circumstances became subversive. The Tunnels is breaking history, a propulsive read whose themes still reverberate.

Book Summary:

TUNNELS deconstructs the individual’s Romantic fascination with ‘love’ or the grammaticality of beauty. Ideally, the ‘tunnels’ in the collection are subterranean love poems from the suburban imaginary. These seemingly syntactic tunnels travel through one’s literary imagination or heterotopic dreamscapes, and while αγάπη (Greek for ‘love’) inspires these rhizomic tunnels to navigate the abysmal ‘meta-spectacle’ of gesture, language or moment of poemness, the mind like the many-colored jeepneys of Manila, where driving past roast goose restaurants in Shek Kip Mei or spotting stilt houses in Kampong Kleang, attempt to explore the transgeneric textualities of the everyday, alongside the unstructurality of time and space, the littoral and the liminal.

Book Summary:

Transportation Tunnels, 2nd Edition provides a comprehensive text on tunneling and tunnel engineering applicable in general to all types of tunnels, with more detailed information on highway and railway tunnels. While the First Edition of the book was confined to deal with railway and highway tunnels, the Second Edition is also extensively considering the latest trends in use of tunnels in different other fields. The book has been revised to provide coverage of water conveyance, navigation and material conveyance tunnels also and deals with these subjects in more detail. It covers all aspects of investigation, design, construction, monitoring and maintenance of tunnels. Special emphasis has been laid on the geotechnical investigations, interpretation of findings and relating the same to the design as well as the construction of tunnels. The book reflects the advancements in the knowledge of ground behaviour and rock mechanics and also in construction technology, including use of TBM in the last two decades. It covers in sufficient detail the basic requirements of tunnel profile, the geometric parameters, clearance requirements, aerodynamics, and cost economics in fixing alignments with different design parameters like curvature, gradient and operational requirements. It discusses in detail alternative forms of the cross section / profile and illustrates design methodology with examples. The different methodologies that have been used in the past using timber or steel supports by stage wise expansion of cross sections and modern methodologies used for boring full profile using new tunneling methods and Tunnel Boring Machines are also comprehensively discussed. Requirements of tunnels in respect of ventilation, lighting and drainage are adequately covered. Separate chapters have been included on ‘Instrumentation’ and ‘Tunnel Inspection and Maintenance’. The expanded text on the use and advantages of methodologies and equipment for dealing with various aspects of construction of tunnels is based on observations through site visits, discussions with, and experiences of people as recorded on large number of tunneling works which have been taken up recently for railways, highways and urban transport subway projects. The book can serve as a textbook for undergraduate and graduate students and as a reference book for practicing engineers.

Book Summary:

At the height of the Vietnam conflict, a complex system of secret underground tunnels sprawled from Cu Chi Province to the edge of Saigon. In these burrows, the Viet Cong cached their weapons, tended their wounded, and prepared to strike. They had only one enemy: U.S. soldiers small and wiry enough to maneuver through the guerrillas’ narrow domain. The brave souls who descended into these hellholes were known as “tunnel rats.” Armed with only pistols and K-bar knives, these men inched their way through the steamy darkness where any number of horrors could be awaiting them–bullets, booby traps, a tossed grenade. Using firsthand accounts from men and women on both sides who fought and killed in these underground battles, authors Tom Mangold and John Penycate provide a gripping inside look at this fearsome combat. The Tunnels of Cu Chi is a war classic of unbearable tension and unforgettable heroes.

Book Summary:

This work illustrates how the Analysis of Controlled Deformation in Rocks and Soils (ADECO-RS) is used in the design and the construction of tunnels. This is a very new and effective way of tunnel construction. The ADECO-RS approach makes a clear distinction between the design and the construction stages and allows reliable forecasts of construction times and costs to be made. It uses the advance core (the core of ground ahead of the face) as a structural tool for the long and short term stabilisation of tunnels, after its rigidity has first been regulated using conservation techniques.

Book Summary:

This book illustrates a new quantitative risk analysis model for road tunnels that is capable of evaluating the role of infrastructure measures, equipment and management procedures as prescribed by EU Directive 2004/54/EC. The risk assessment draws on the typical F-N curves of societal risk, evaluated with the help of event tree analysis, vehicle queue formation dynamics, and users’ egress and tenability models. In addition, the model considers the reliability of the safety measures. The work provides essential guidance on the following aspects: how a quantitative model can be implemented to evaluate risk in road tunnels; how to build an event tree for the accident scenarios considered; how to simulate the vehicle queue formation; how to simulate the evolution of accident scenarios; and how to simulate the users’ egress. Given its scope and depth of coverage, the book will be of interest to all engineers whose work involves fire protection and safety in tunnels, all persons engaged in safety and transport engineering or risk analysis for road tunnels, as well as public and private bodies involved in the application of Directive 2004/54/EC.

Book Summary:

During the Vietnam War, the Viet Cong (VC) main forces and North Vietnamese Army (NVA) were forced to hide weapons and supplies underground and to dig protective shelters to counter massive US firepower. Their field works defended villages, hidden base camps, and fortified complexes, and took the form of trench systems, individual fighting positions, crew-served weapon positions, bunkers, caches, and extensive tunnel complexes. Camouflage and deceptive measures, and the employment of obstacles and booby traps, went hand-in-hand with such works. This title takes a detailed look at the VC/NVA tunnel systems, field fortifications, base camps. and camouflage and concealment measures employed during the Vietnam conflict.

Explore Philadelphia's relationship with the underground, as old as the city itself, dating back to when Quaker settlers resided in caves alongside the Delaware River more than three hundred years ago. Explore the city under the The City of Brotherly Love, which became a national and world leader in the delivery of water, gas, steam, and electricity during the industrial age. The construction of multiple subway lines within Center City took place during the early twentieth century. An intricate subsurface pedestrian concourse was also developed throughout the downtown area for the city's inhabitants. From Thirtieth Street Station and Reading Terminal to the Commuter Rail Tunnel and transit lines that were never built, Philadelphia's infrastructure history is buried under the earth as much as above. Join authors Harry Kyriakodis and Joel Spivak as they reveal the curious aspects of the Quaker City's underground experience.

Book Summary:

Sprayed concrete lined (SCL) tunnels are growing rapidly in popularity due to their versatility. The design and construction of both hard rock and soft ground tunnels has been revolutionised by the advent of the SCL method and now the use of permanent sprayed concrete linings has unlocked the true potential of the method to minimise construction costs and times. Yet the complex early age behaviour of the sprayed concrete makes the design difficult and requires a robust management system during construction. Consequently the great advantages of the method must be balanced against the risks, as a few high-profile tunnel collapses have illustrated. Practising engineers on site, in the design office or in client organizations will find this book an excellent introduction. It covers all aspects of SCL tunnelling – from the constituents of sprayed concrete to detailed design and management during construction. Although there is a close interdependence between all the facets of sprayed concrete, few engineers have the right breadth of experience and expertise to cover all of them. This urgently needs to be transferred to the wider engineering community as SCL tunnels play an increasingly important role in the delivery of the underground infrastructure which modern urban life demands. In this second edition, beyond a general updating to reflect new developments, the sections on permanent sprayed concrete, the innovative technology of spray applied waterproofing membranes, fibre reinforcement (both steel and macrosynthetic) and composite lining design have been expanded. Sustainability and environmental impact are addressed in a new section.

Book Summary:

This book addresses development laws for axial strain and excess pore water pressure in silty clay around subway shield tunnels before and after freezing-thawing when subjected to subway loading, as well as the effect of freezing-thawing on the dynamic parameters of silty clay, including the dynamic modulus and damping ratio, introducing readers to the design and construction of bypasses in subway tunnels with the artificial freezing method. On this basis, it then studies the microstructures of silty clay before and after freezing-thawing cyclic loading by means of scanning electron microscope tests and mercury intrusion porosimetry tests. Lastly, the book presents a numerical simulation of the dynamics of silty clay around subway tunnels before and after thawing. Given its scope, it offers a valuable reference guide for construction researchers and designers alike, as well as senior undergraduate and graduate students at colleges and universities.

Book Summary:

Tunnel engineering is one of the oldest, most interesting but also challenging engineering disciplines and demands not only theoretical knowledge but also practical experience in geology, geomechanics, structural design, concrete construction, machine technology, construction process technology and construction management. The two-volume "Handbuch des Tunnel- und Stollenbaus" has been the standard reference for German-speaking tunnellers in theory and practice for 30 years. The new English edition is based on a revised and adapted version of the third German edition and reflects the latest state of knowledge. The book is published in two volumes, with the first being devoted to more practical themes of construction and construction process in drill and blast and mechanised tunnelling. Microtunnelling and ventilation are also dealt with. All chapters include practical examples.

Book Summary:

Infrastructure is something that we use every day, like roads, bridges, and tunnels, but probably never think too much about. However, in the United States, many parts of the country’s infrastructure are old, falling apart, and desperately need repair and upgrading. Tunnels especially are vital to transportation, and extremely dangerous when they collapse. This book explores eight tunnels of different types that are lifelines for transportation in the US, but are now at risk. Whether its Boston’s Big Dig, the twin railroad tunnels under the Hudson River, California’s Hetch Hetchey water system, or a rail tunnel in Baltimore that’s more than 100 years old, these tunnels are very important to the entire country. Without emergency repairs and expansion, these tunnels could fail, with catastrophic results.

Book Summary:

Virtual private networks (VPNs) based on the Internet instead of the traditional leased lines offer organizations of all sizes the promise of a low-cost, secure electronic network. However, using the Internet to carry sensitive information can present serious privacy and security problems. By explaining how VPNs actually work, networking expert Jon Snader shows software engineers and network administrators how to use tunneling, authentication, and encryption to create safe, effective VPNs for any environment. Using an example-driven approach, VPNs Illustrated explores how tunnels and VPNs function by observing their behavior "on the wire." By learning to read and interpret various network traces, such as those produced by tcpdump, readers will be able to better understand and troubleshoot VPN and network behavior. Specific topics covered include: Block and stream symmetric ciphers, such as AES and RC4; and asymmetric ciphers, such as RSA and EIGamal Message authentication codes, including HMACs Tunneling technologies based on gtunnel SSL protocol for building network-to-network VPNs SSH protocols as drop-in replacements for telnet, ftp, and the BSD r-commands Lightweight VPNs, including VTun, CIPE, tinc, and OpenVPN IPsec, including its Authentication Header (AH) protocol, Encapsulating Security Payload (ESP), and IKE (the key management protocol) Packed with details, the text can be used as a handbook describing the functions of the protocols and the message formats that they use. Source code is available for download, and an appendix covers publicly available software that can be used to build tunnels and analyze traffic flow. VPNs Illustrated gives you the knowledge of tunneling and VPN technology you need to understand existing VPN implementations and successfully create your own.

Book Summary:

Examine the inner workings of the mind and learn what consciousness and a sense of self really means - and if it even exists. We're used to thinking about the self as an independent entity, something that we either have or are. In The Ego Tunnel, philosopher Thomas Metzinger claims otherwise: No such thing as a self exists. The conscious self is the content of a model created by our brain-an internal image, but one we cannot experience as an image. Everything we experience is "a virtual self in a virtual reality."But if the self is not "real," why and how did it evolve? How does the brain construct it? Do we still have souls, free will, personal autonomy, or moral accountability? In a time when the science of cognition is becoming as controversial as evolution, The Ego Tunnel provides a stunningly original take on the mystery of the mind.

Book Summary:

FM 7-41 Written near the end of the Vietnam War in 1973 field manual highlights the training and use of war dogs specifically as mine/booby trap detection dogs. Detailed methods, equipment, and training instruction specifics are covered in detail, from the Food-Reward method thru Basic Detection training and on to Intermediate/Advanced training in simulated field conditions. The ability to also detect tunnels and or weapons caches is also covered. As the Vietnam war heated up and more U.S. troops were pouring into the conflict in the late 1960's it became apparent that the Vietcong's use of mines and booby traps to maim and kill American soldiers remotely was becoming especially effective. The dog training techniques presented are both straightforward and simple to understand, using methods pioneered in the late 60's to counter the enemies use of mines and other guerilla warfare explosive device attacks. This manual is a wealth of information for any dog handler or trainer interested in dog training methodology and for insights into the special capabilities of detection dogs in general. It is a rare look into the use of Army dogs in the counter-insurgency fight in South-East Asia. Keywords: war dog,k9,detection,explosives,trip wire,booby trap,cache,scout,handler,german shepherd

Book Summary:

Starting in the 1950s, US physicists dominated the search for elementary particles; aided by the association of this research with national security, they held this position for decades. In an effort to maintain their hegemony and track down the elusive Higgs boson, they convinced President Reagan and Congress to support construction of the multibillion-dollar Superconducting Super Collider project in Texas—the largest basic-science project ever attempted. But after the Cold War ended and the estimated SSC cost surpassed ten billion dollars, Congress terminated the project in October 1993. Drawing on extensive archival research, contemporaneous press accounts, and over one hundred interviews with scientists, engineers, government officials, and others involved, Tunnel Visions tells the riveting story of the aborted SSC project. The authors examine the complex, interrelated causes for its demise, including problems of large-project management, continuing cost overruns, and lack of foreign contributions. In doing so, they ask whether Big Science has become too large and expensive, including whether academic scientists and their government overseers can effectively manage such an enormous undertaking.
