It is the forty-first century. Falling prey to unimagined solar processes, the sun has exploded and destroyed the Earth. Thousands of survivors move outward into space aboard the Space Star Silver Streak. Thirteen years have passed as they search for habitable planets to colonize. Now, with the ship almost emptied, the mission nearly at an end, the most recently established colony signals distress. Something huge, ominous, mysterious, and inexplicable is wandering through the galaxy. Ten years ago Captain Richard Cameron resigned from command. Faced with a new and completely unexplained crisis, he returns to the bridge, reunites his old crew, and sets off on a voyage that may mean the end of his career or the salvation of civilization--or both! A voyage to the limits of knowledge, a voyage to the height of human potential... A voyage into the unknown!
The book is a reflection on childhood, dealing especially with children's wellbeing and the implementation of their rights. Starting from the recognition – first expressed in the 1924 Declaration of the Rights of the Child and reaffirmed in the 2000 Treaty of Nice as well as in more recent initiatives of the European Union – that children must be granted the right to be considered as persons and afforded the best possible living conditions, the book's aim is to create a dialog among scholars with different backgrounds. For this reason, it draws on a range of different vocabularies, conceptual apparatuses and methodologies, as we are convinced that it is reductive to confine research and ...
For fourteen years the Space Star Silver Streak has ranged through deep space searching for planets to colonize. Now the long voyage is nearing its end. The ship is almost empty. If one more planet checks out for colonization, the last of the great space ark's complement will disembark and the long rebuilding of the human race will begin. But the Hyron commander Mordrax, who has ruthlessly pursued the Silver Streak across the galaxy in his mad desire to kill Captain Richard Cameron, has now ascended to the throne of Hyron. As the Silver Streak prepares for what may be its last planetary survey, Mordrax's Hyron fleet arrives on an apparent mission of peace. Could Mordrax be sincere in his desire for an alliance with his old enemy? Or is this a deadly trap that could spell the end of the human race?
In the never-ending quest for miniaturization, optically controlled particle trapping has opened up new possibilities for handling microscopic matter non-invasively. This thesis presents the application of photorefractive crystals as active substrate materials for optoelectronic tweezers. In these tweezers, flexible optical patterns are transformed into electrical forces by a photoconductive material, making it possible to handle matter with very high forces and high throughput. Potential substrate materials’ properties are investigated and ways to tune their figures-of-merit are demonstrated. A large part of the thesis is devoted to potential applications in the field of optofluidics, where photorefractive optoelectronic tweezers are used to trap, sort and guide droplets or particles in microfluidic channels, or to shape liquid polymers into optical elements prior to their solidification. Furthermore, a new surface discharge model is employed to discuss the experimental conditions needed for photorefractive optoelectronic tweezers.
Admiral Mordrax, the Hyron commander whose bloodlust has pursued Richard Cameron and the Space Star Silver Streak across the galaxy for thirteen years, returns with an awesome new warship to finally destroy his old enemy! In this, the biggest, most awe-inspiring Voyage Into the Unknown adventure ever, the Silver Streak is brought to the brink of destruction! When the bridge is shattered, Richard Cameron, Frank Johnson, Jack Hasta, and Philippe Stargazer awaken...a thousand years later! Trapped aboard a battered remnant of the Silver Streak which is disintegrating around them, the old friends must work with their own descendants to try to find a way home--even if it means killing their daughters in the process!

Who invented the cork? And when? The answers to these and many other questions are revealed on a journey back through eight thousand years and the civilisations who have populated the western world. The ancestors of the cork (and caps, and stoppers, and lids!) were found hiding in the first Neolithic settlements in Iran and among the ruins of Cretan civilisations, in the markets in ancient Egypt and on Phoenician ships. In more recent times, when stoppers began to take on the shape we are familiar with, they were protected by the laws of the Venetian Republic, or preserved as relics in the ancient abbey in Hautvillers, where dom Pérignon was the first to stopper a champagne bottle with a co...
The optical filter is resonator based. The required passband shape of ring resonator-filters can be custom designed by the use of configurations of various ring coupled resonators. This book describes the current state-of-the-art on these devices. It provides an in-depth knowledge of the simulation, fabrication and characterization of ring resonators for use as example filters, lasers, sensors.
This book, written by leading international researchers of evolutionary approaches to machine learning, explores various ways evolution can address machine learning problems and improve current methods of machine learning. Topics in this book are organized into five parts. The first part introduces some fundamental concepts and overviews of evolutionary approaches to the three different classes of learning employed in machine learning. The second addresses the use of evolutionary computation as a machine learning technique describing methodologic improvements for evolutionary clustering, classification, regression, and ensemble learning. The third part explores the connection between evoluti...
Anche se non vogliamo crederci, corriamo tutta una vita per cercare di darle un significato, un sapore. Talvolta ci spingiamo sino a stravolgerla, pur sapendo molto bene che il nostro destino è già stato scritto e non possiamo cambiarlo: è stato deciso nel preciso momento in cui siamo venuti al mondo. Travolgente il romanzo di Mirco Zaltron, che ci fa fare i conti con la quotidianità che spesso affrontiamo di petto, sconvolgendoci e rimanendo a dimenarci in un mondo di detto e non detto. Un frastuono di emozioni, vicende, rimpianti, prospettive e molto altro, che possono sconvolgersi e sconvolgere noi in una frazione di secondo, mettendoci di fronte alla nostra piccolezza e fragilità. U...
