Hardrock Tunnel Boring Machines

By: Bernhard Maidl,Leonhard Schmid,Willy Ritz,Martin Herrenknecht

This book covers the fundamentals of tunneling machine technology: drilling, tunneling, waste removal and securing. It treats methods of rock classification for the machinery concerned as well as legal issues, using numerous example projects to reflect the state of technology, as well as problematic cases and solutions. The work is structured such that readers are led from the basics via the main functional elements of tunneling machinery to the different types of machine, together with their areas of application and equipment. The result is an overview of current developments. Close cooperation among the authors involved has created a book of equal interest to experienced tunnelers and newcomers.

Bikini Bravo

Maskirovka

By: Willy Mitchell

It has been several years since the author, Willy Mitchell, was in East Africa and visited a bar in Malindi, Kenya. He overheard the rumblings of a coup-in-the-making without any idea that one day in the future, a similar plan would be hatched. Now, years later, Mitch’s daughter, Bella, has followed in her father’s footsteps where he served in the British Special Air Service, and joined the CIA, where she has transformed into a rising star. Russian villain Dimitri Dankov has already sought revenge after a failed assassination attempt. Bella and the team of Mitch, Mac, Bob, and Sam, with Colonel Collins and Lord Beecham, discover that the leading Mexican drug cartels have partnered with Russian dark forces to take over Equatorial Guinea in an attempt to win influence in Africa and transform the cartel’s dirty money into good. Bella and Mitch lead the charge against the dark forces hidden under the veil of Maskirovka. But what can they do to change this course of events? In this tale of intrigue, money laundering at the highest level, and corruption, a rising CIA star, her father, and their team find themselves drawn into a complex plot involving greedy oil executives, drug cartels, and the Russian underworld from taking over an oil-rich African nation.

Cold Courage

Extraordinary Times

By: Willy Mitchell

Cold Courage relates back to Willy Mitchell's grandfathers meeting with Harry McNish in Wellington, New Zealand and in exchange for a hot meal and a pint or two, he told his story of The Endurance. Flipping through the London Times, McNish had come across a classified advertisement for the crew to join a ship's journey to the Antarctic and on to the South Pole. It warned of low wages and high danger and at forty, he decided that he wanted a taste of adventure and set off to London to meet the rest of the newly recruited crew. On 6th August 1914, The Endurance set sail from Plymouth, England on its way to Buenos Aires, Argentina and meet with the entire 28-man crew. This is a tale of the great age of exploration and the extraordinary journey that these men endured, not only in Antarctica but upon their return to England amidst the Great War and their legendary lives thereafter. This is the story of Harry McNish and although set in a different era, continues the ARGUS series and a homage to those brave men and women who go to extraordinary lengths to achieve their goals.

Photonic Crystals: Mathematical Analysis and Numerical Approximation

By: Willy Dörfler,Armin Lechleiter,Michael Plum,Guido Schneider,Christian Wieners

This book concentrates on the mathematics of photonic crystals, which form an important class of physical structures investigated in nanotechnology. Photonic crystals are materials which are composed of two or more different dielectrics or metals, and which exhibit a spatially periodic structure, typically at the length scale of hundred nanometers. In the mathematical analysis and the numerical simulation of the partial differential equations describing nanostructures, several mathematical difficulties arise, e. g., the appropriate treatment of nonlinearities, simultaneous occurrence of continuous and discrete spectrum, multiple scales in space and time, and the ill-posedness of these problems. This volume collects a series of lectures which introduce into the mathematical background needed for the modeling and simulation of light, in particular in periodic media, and for its applications in optical devices.

It is not long before Mitch and his colleagues determine foul play in the death of their friend. Unfortunately, he is not the first SAS operative to die under bizarre circumstances. As Mitch leads the charge to investigate the mysterious death, their quest for the truth takes them from San Francisco to London, from Lithuania to Moscow and to Tangiers in Morocco where they must survive many challenges. But do they have what it takes to thwart the dark forces that lurk in the shadows and under a veil of Maskirovka? In this international political thriller, a group of British Special Forces soldiers become intertwined in a complex mystery involving a drug cartel, the CIA, the IRA, and the Russian mob while investigating a former colleague’s mysterious death.

Ss Indigo

Twelve's Company

By: Willy Mitchell

It is 2003 and Igor Bromovich has just been hired to captain the luxury steamship, SS Indigo, for an upcoming private cruise around the Caribbean. He is thrilled to be returning to work, and to a place he belongs. Assisted by a small crew of three, including Californian Zach Carter, he shelves the doubts that have been creeping into his thoughts and readies the ship for the five-hundred-mile sail to Grand Cayman. Sir James Parsons is a leading investor and businessman who is prepared to carry out his swan song, a homage to the father who never voiced his approval for any of Parsons’ accomplishments. He is joined by an eclectic group of strangers to board the ship and the mystery cruise, all having received mysterious invitations to board the Indigo at St. Georges Caye, Belize, to hear about a once-in-a-lifetime investment opportunity. The passengers arrive to embark on a journey of intrigue and discovery without realizing that they all have one thing in common. Now just one question remains: When the ship docks in Grand Cayman, how many of the passengers will be left? In this gripping mystery on the sea, a reclusive and secretive billionaire invites a small group of strangers to cruise the Caribbean on a luxury steamship where they soon discover that nothing is as it seems, and that the road to hell is paved with good intentions.

Numerical Methods for Bifurcations of Dynamical Equilibria

By: Willy J. F. Govaerts

Dynamical systems arise in all fields of applied mathematics. The author focuses on the description of numerical methods for the detection, computation, and continuation of equilibria and bifurcation points of equilibria of dynamical systems. This subfield has the particular attraction of having links with the geometric theory of differential equations, numerical analysis, and linear algebra.
