The use of lasers for various applications in materials processing has grown rapidly in recent years. Lasers are by nature particularly well suited to automation, but to ensure repeatability and reliability, the engineers employing them must not simply rely on numerical analysis software. They must have a firm grasp on the physical principles involved.

Mathematics of Thermal Modelling: An Introduction to the Theory of Laser Material Processing introduces the mathematics needed to formulate and exploit the physical principles important to modelling various aspects of laser material processing. The author shows how to gain insight by constructing and analyzing simple models. He demonstrates how to extract qualitative information from the models, how the underlying principles can be extended to more complex modelling, and how these principles can be applied to processes such as laser welding, surface treatment, drilling, and cutting.

Written at a level accessible to graduate students, this book shows that simple mathematical investigation-- based primarily on analytical methods backed by relatively simple numerical methods--can greatly illuminate the processes being studied. Regardless of the stage of your career development, if you are confronting the modelling of thermal process in this field for the first time, Mathematics of Thermal Modelling will build the foundation you need.

Dane Cook and Stacy Keach return as the voices of lovable aeroplanes Dusty and Skipper in this sequel to the 2013 Disney animation 'Planes'. When world-famous air racer Dusty gets told his engine is damaged and that he may never race again he refuses to let go and launches head first into the world of aerial firefighting. Joining the ranks of veteran fire and rescue helicopter Blade Ranger (Ed Harris), Dusty begins his training to become a real hero. The voice cast also includes Jerry Stiller, Steve Schirripa and Erik Estrada.

Crop circles are the finest, most beautiful and original art forms of modem times, and they are totally mysterious. Behind the crop circle phenomenon is an evident purpose. Some intelligence, human, alien or spiritual, is in the process of communication. It is exposing us to a course of re-education, beginning with the symbols of sacred knowledge and wisdom. The most striking evidence for this view is the amazing formation that appeared at Crooked Soley in Wiltshire on the 27th August 2002. Clearly expressed in its design are certain numerical symbols that are known esoterically as the 'Keys to Creation'. They are also keys to that universal science associated with the Holy Grail. From time to time it is revealed again, and when that happens, culture and the human spirit are renewed and life on earth is restored to its natural state as a reflection of paradise.

John Austin, known as Auty, is not an impulsive man. But even so, he decides to abandon a successful and lucrative law practice that's won him notoriety and a reputation for integrity.

When a big case is on the line, Auty is the suit you want in your corner. And he owes it all to his friend, mentor, and senior partner of his law firm, Ed Fielding. So Auty doesn't think twice about taking a plane from Wisconsin to Florida to break the news to the old man in person. He hopes to find some time to relax in the sun, but there will be no downtime on this trip.

What terrible secret has Ed Fielding been keeping from Auty all these years? Why is Auty giving up a six million dollar inheritance? Why is he risking his life for a gorgeous flight attendant and a teenage college student he barely knows? And why are there suddenly people trying to kill him?

Join Auty as he pursues his dreams, tries to save his friends, and uncovers mysteries in Gold Fish.

As a sinner enters the confessional, he glances about the empty church. Father Dan Rutledge waits patiently for Ray Cronin to begin his declarations of guilt. No one hears the squeak of church door as a tall shadow quietly enters and trains his weapon on the confessional doors. Moments later, Ray Cronin is dead, Father Dan Rutledge is barely hanging on, and the only thing everyone knows is that someone has already killed four priests in Dade County in the last six months.

Framed by America's enemies for a crime she didn't commit. Fifteen-year-old Colleen Lee "Collie" Knight is on trial for her life in a foreign land. If she's found guilty, then the Monarchy of The Kingdom's Realm will off the American teen a blindfold as she stands in front of their military firing squad. Will Collie be spared from sitting in her prison cell waiting in fearful anticipation for her execution day to arrive? Can the efforts of her friends and family and American President Virgina Watker save Collie if she's found guilty by the Grand Council of the Realm and sentenced to Death?
