Brace yourself for a fun challenge: build a photorealistic 3D renderer from scratch! In just a couple of weeks, build a ray tracer that renders beautiful scenes with shadows, reflections, refraction effects, and subjects composed of various graphics primitives: spheres, cubes, cylinders, triangles, and more. With each chapter, implement another piece of the puzzle and move the renderer forward. Use whichever language and environment you prefer, and do it entirely test-first, so you know it's correct.

Imagine The Bourne Identity meets Gravity and you'll get TRACER, the most exciting thriller set in space you'll ever read. A huge space station orbits the Earth, holding the last of humanity. It's broken, rusted, falling apart. We've wrecked our planet, and now we have to live with the consequences: a new home that's dirty, overcrowded and inescapable. What's more, there's a madman hiding on the station. He's about to unleash chaos. And when he does, there'll be nowhere left to run. In space, every second counts. Who said nobody could hear you scream? 'Fast, exhilarating and unforgettable, and once you start it you can't stop' Sarah Lotz, author of The Three 'A stunning debut that never lets up, from the nerve-jangling beginning to the explosive end' James Douglas, author of The Doomsday Machine 'TRACER sets a new standard for all-action SF' Ken MacLeod

In the vein of great box-office blockbusters, the high-stakes romance here sizzles within this page-turning thriller that will leave readers feeling like they are flying through the streets of New York. Cam has come to accept the rhythm of his life as a bike messenger: racing up and down the streets of New York City from one run to the next. With no family to rely on and a mountain of debts, at least it’s an honest way to help pay off his dangerous debtors. Cam’s whole world comes crashing down on him one day when he runs into a beautiful stranger. After falling out of the sky and wiping out Cam and his bike, she disappears before he can find out anything about her. When he starts to see her around town, he quickly realizes that she is part of an underground group of teens who have turned NYC into their own parkour playground—running, jumping, seemingly flying through the city like it’s an obstacle course. Cam becomes fascinated with the sport—and the beautiful stranger, Nikki. He falls in with the group, and they offer him the chance to make some extra money. But when the stakes become life or death, Cam is torn between following his heart and sacrificing everything to pay off his debts.

The tracer method was first introduced to measure the actual flow of fluid in a vessel, and then to develop a suitable model to represent this flow. Such models are used to follow the flow of fluid in chemical reactors and other process units, in rivers and streams, and through soils and porous structures. Also, in medicine they are used to study the flow of chemicals, harmful or not, in the blood streams of animals and man. Tracer Technology, written by Octave Levenspiel, shows how we use tracers to follow the flow of fluids and then we develop a variety of models to represent these flows. This activity is called tracer technology.

From the award-winning author of Sandworm comes the propulsive story of a new breed of investigators who have cracked the Bitcoin blockchain, exposing once-anonymous realms of money, drugs, and violence. “I love the book… It reads like a thriller… These stories are amazing.” (Michael Lewis) Over the last decade, a single innovation has massively fueled digital black markets: cryptocurrency. Crime lords inhabiting lawless corners of the internet have operated more freely—whether in drug dealing, money laundering, or human trafficking—than their analog counterparts could have ever dreamed of. By transacting not in dollars or pounds but in currencies with anonymous ledgers, overseen by no government, beholden to no bankers, these black marketeers have sought to rob law enforcement of their chief method of cracking down on illicit finance: following the money. But what if the centerpiece of this dark economy held a secret, fatal flaw? What if their currency wasn’t so cryptic after all? An investigator using the right mixture of technical wizardry, financial forensics, and old-fashioned persistence could uncover an entire world of wrongdoing. Tracers in the Dark is a story of crime and pursuit unlike any other. With unprecedented access to the major players in federal law enforcement and private industry, veteran cybersecurity reporter Andy Greenberg tells an astonishing saga of criminal empires built and destroyed. He introduces an IRS agent with a defiant streak, a Bitcoin-tracing Danish entrepreneur, and a colorful ensemble of hardboiled agents and prosecutors as they delve deep into the crypto-underworld. The result is a thrilling, globe-spanning story of dirty cops, drug bazaars, trafficking rings, and the biggest takedown of an online narcotics market in the history of the Internet. Utterly of our time, Tracers in the Dark is a cat-and-mouse story and a tale of a technological one-upmanship. Filled with canny maneuvering and shocking twists, it answers a provocative question: How would some of the world’s most brazen criminals behave if they were sure they could never get caught?

A workbook that can help health care organizations use mock (practice) tracers to identify unrecognised environment of care (EC), emergency management (EM), and life safety (LS) compliance and safety issues and implement changes as part of an ongoing improvement process-before a survey takes place.

This book is concerned with the application of tracers to a wide variety of oil field operations. It provides the necessary nuclear concepts and techniques which are basic to oil field tracer applications. Laboratory and field techniques are explained and illustrated as are the associated regulatory and safety aspects. Within the book, each area of oil field use is considered separately and specific applications of tracers discussed and relevant literature reviewed. The use of non-radioactive tracers is pointed out wherever it is applicable.Due to the nature of this competitive industry, much research is poorly documented, thus Tracers in the Oil Field aims to make the technology more available to current users in the oil field.
