This is a book about infrastructure networks that are intrinsically nonlinear. The networks considered range from vehicular networks to electric power networks to data networks. The main point of view taken is that of mathematical programming in concert with finite-dimensional variational inequality theory. The principle modeling perspectives are network optimization, the theory of Nash games, and mathematical programming with equilibrium constraints. Computational methods and novel mathematical formulations are emphasized. Among the numerical methods explored are network simplex, gradient projection, fixed-point, gap function, Lagrangian relaxation, Dantzig-Wolfe decomposition, simplicial decomposition, and computational intelligence algorithms.Many solved example problems are included that range from simple to quite challenging. Theoretical analyses of several models and algorithms, to uncover existence, uniqueness and convergence properties, are undertaken. The bookis meant for use in advanced undergraduate as well as doctoral courses taught in civil engineering, industrial engineering, systems engineering, and operations research degree programs. At the same time, the book should be a useful resource for industrial and university researchers engaged in the mathematical modeling and numerical analyses of infrastructure networks.

Then with the help of his magic rope he discovers he can visit his mom anytime he wants. "Jack stood there among the wildflowers and never ending fields of dreams. His Magic was missing one small red flower. He knew that his mom had kept it. Then a huge smile appeared on his face, and the Alaskin sun smiled back at him.
One little girl's journey from sadness to obsession and finally freedom Wendy loves her father very much and enjoys doing many things with him. But one day he leaves-her parents are getting a divorce-and he's not coming back. Wendy is left with a deep sadness and no way to cope with it, so she turns to peanut butter and cheese sandwiches, which remind her of her dad. And her obsession begins. It will take a loving mother and a sweet little homeless dog named Peanut to help Wendy overcome her grief and finally begin to heal.

What if the sky was deadly?Fin has never stepped foot on the surface of the Earth. Working the mines, deep below, has been the only life she's ever known. The underground is nothing more than an existence of sweat and monotony in service to the Enhanced Human Coalition-the genetically-modified who control the underground from the world above. Every Dweller underground understands that you serve the EHC up top, or you don't eat.Two hundred years after the planet's magnetic poles began to flip, Earth's surface has become irradiated and unsustainable. As the land, water, and even the air grew toxic, the underprivileged were doomed to a life of hard labor underground, while the Enhanced Human Coalition on the surface enjoy their spoils.But now, Fin and her friends discover a stolen piece of EHC tech that modifies genetics, giving them the abilities of those up top-varied levels of increased strength, intelligence, and adaptation to the surface's harsh conditions. The theft of this technology triggers a manhunt, forcing them to flee to the most dangerous place they could possibly go... aboveground.Can she save a world broken in two?Fans of The Maze Runner, Configured, and Influence will devour this fast-paced, innovative sci-fi adventure.

We're losing hundreds of billions of dollars a year on broken software, and great new ideas such as agile development and Scrum don't always pay off. But there's hope. The nine software development practices in Beyond Legacy Code are designed to solve the problems facing our industry. Discover why these practices work, not just how they work, and dramatically increase the quality and maintainability of any software project. These nine practices could save the software industry. Beyond Legacy Code is filled with practical, hands-on advice and a common-sense exploration of why technical practices such as refactoring and test-first development are critical to building maintainable software. Discover how to avoid the pitfalls teams encounter when adopting these practices, and how to dramatically reduce the risk associated with building software--realizing significant savings in both the short and long term. With a deeper understanding of the principles behind the practices, you'll build software that's easier and less costly to maintain and extend.By adopting these nine key technical practices, you'll learn to say what, why, and for whom before how; build in small batches; integrate continuously; collaborate; create CLEAN code; write the test first; specify behaviors with tests; implement the design last; and refactor legacy code. Software developers will find hands-on, pragmatic advice for writing higher quality, more maintainable, and bug-free code. Managers, customers, and product owners will gain deeper insight into vital processes. By moving beyond the old-fashioned procedural thinking of the Industrial Revolution, and working together to embrace standards and practices that will advance software development, we can turn the legacy code crisis into a true Information Revolution.
I can't get enough. I love these characters, I love the world building and I love the storyline ★★★★★First the floods consumed the Earth.Then the Syndicate took everything from me.My childhood, my first love-my humanity.Before I was born, the rising oceans consumed the last land on Earth. All I've ever known is a fight for survival. But the Syndicate wants to change this, genetically adapting children to fit this harsh new world-no matter how many lives are sacrificed in the process.When little, I was ripped from my home to take part in the Syndicate's cruel experiments. But I broke free. Now, at the age of seventeen, I'm hunted for my unique ability to thrive beneath the ocean's depths, but also because I rescue others held captive by the Syndicate.Every day is a predictable struggle, the same watery grave of fears. Everything changes on a routine patrol of a Syndicate vessel, however, when I stumble across two people-a highly sought-after prisoner who was designed to be more powerful than myself and a young man from my past, one my heart never forgot.These two ghosts from my past will most likely jeopardize all the work I've achieved against the Syndicate. But I can't leave them behind. Even if I lose everything in saving them, including my very life.Note: Reckless is a re-brand of the novel, NeverSea with improved editing and adjusted character naming.

After falling into a time portal during a Little League baseball game in Trinity, New York, eleven-year-old Andy finds himself transported to a ghostly version of his hometown-101 years in the future. Twisted metal, rotten wood, and garbage litter the seemingly empty streets, but Andy will soon discover that the city is controlled by CORT robots . . . and that this reality is Earth's possible future. When thirteen-year-old Zack receives a strange letter that guides him through the portal, he and his brother are reunited, and together they must journey through a nightmare world that only they can change. But how can two young boys alter the present by saving the future?
