Initial training in pure and applied sciences tends to present problem-solving as the process of elaborating explicit closed-form solutions from basic principles, and then using these solutions in numerical applications. This approach is only applicable to very limited classes of problems that are simple enough for such closed-form solutions to exist. Unfortunately, most real-life problems are too complex to be amenable to this type of treatment. Numerical Methods – a Consumer Guide presents methods for dealing with them.Shifting the paradigm from formal calculus to numerical computation, the text makes it possible for the reader to · discover how to escape the dictatorship of those particular cases that are simple enough to receive a closed-form solution, and thus gain the ability to solve complex, real-life problems;· understand the principles behind recognized algorithms used in state-of-the-art numerical software;· learnthe advantages and limitations of these algorithms, to facilitate the choice of which pre-existing bricks to assemble for solving a given problem; and· acquire methods that allow a critical assessment of numerical results. Numerical Methods – a Consumer Guide will be of interest to engineers and researchers who solve problems numerically with computers or supervise people doing so, and to students of both engineering and applied mathematics.

Modern vehicles have electronic control units (ECUs) to control various subsystems such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (or simply ‘controllers’) are networked together to share information, and output directly measured and calculated data to each other. This in-vehicle network is a data goldmine for improved maintenance, measuring vehicle performance and its subsystems, fleet management, warranty and legal issues, reliability, durability, and accident reconstruction.The focus of Data Acquisition from HD Vehicles Using J1939 CAN Bus is to guide the reader on how to acquire and correctly interpret data from the in-vehicle network of heavy-duty (HD) vehicles. The reader will learn how to convert messages to scaled engineering parameters, and how to determine the available parameters on HD vehicles, along with their accuracy and update rate.Written by two specialists in this field, Richard (Rick) P. Walter and Eric P. Walter, principals at HEM Data, located in the United States, the book provides a unique road map for the data acquisition user. The authors give a clear and concise description of the CAN protocol plus a review of all 19 parts of the SAE International J1939 standard family. Pertinent standards are illuminated with tables, graphs and examples.Practical applications covered are calculating fuel economy, duty cycle analysis, and capturing intermittent faults. A comparison is made of various diagnostic approaches including OBD-II, HD-OBD and World Wide Harmonized (WWH) OBD.Data Acquisition from HD Vehicles Using J1939 CAN Bus is a must-have reference for those interested to acquire data effectively from the SAE J1939 equipped vehicles.
Robbie's father is a Spitfire pilot who was shot down during World War II and is now a POW. At only seventeen, Robbie lies about his identity to enlist in the Royal Canadian Air Force under the guise of going to a boarding school so that his mother doesn't find out. He starts training in Brandon, Manitoba, but after acing all his classes, he's dealt a disappointing blow when he's assigned to be a navigator on a Lancaster. He wanted to be a pilot, just like his father, but the commanders of the air force have other ideas. Robbie is soon on his way to England, where he completes his training on missions bombing German targets in enemy territory. It is during one of these missions that his Lancaster is fired upon and the pilot and many of the crew are shot. It's up to Robbie and his limited piloting experience to save the crew...and himself.
Ethan can barely believe it. Until now, his biggest problems have been trying to stay in one school without getting expelled ... and finding his next drink. But after Ethan's drunken imitation of the school's headmaster goes up on YouTube, his father steps in with a shockingly drastic measure. Now Ethan is sprawled in the sand ... in the Sahara Desert. Alone. According to his father's letter, Ethan must trek 200 kilometres across the desert to the city of Tunis, with the help of a guide and three other young people. Confused, hungover, and--if he is truthful--more than a little scared, Ethan has no choice. He will face sandstorms, vipers, and agonizingly painful blisters ... but, most painful of all, he will confront his inner demons and come to a true realization of who he really is.

A violin and a middle-school musical unleash a dark family secret in this moving story by an award-winning author duo. For fans of The Devil's Arithmetic and Hana's Suitcase. It's 2002. In the aftermath of the twin towers -- and the death of her beloved grandmother -- Shirli Berman is intent on moving forward. The best singer in her junior high, she auditions for the lead role in Fiddler on the Roof, but is crushed to learn that she's been given the part of the old Jewish mother in the musical rather than the coveted part of the sister. But there is an upside: her "husband" is none other than Ben Morgan, the cutest and most popular boy in the school. Deciding to throw herself into the role, she rummages in her grandfather's attic for some props. There, she discovers an old violin in the corner -- strange, since her Zayde has never seemed to like music, never even going to any of her recitals. Showing it to her grandfather unleashes an anger in him she has never seen before, and while she is frightened of what it might mean, Shirli keeps trying to connect with her Zayde and discover the awful reason behind his anger. A long-kept family secret spills out, and Shirli learns the true power of music, both terrible and wonderful.
One shocking afternoon, computers around the globe shut down in a viral catastrophe. At sixteen-year-old Adam Daley's high school, the problem first seems to be a typical electrical outage, until students discover that cell phones are down, municipal utilities are failing, and a few computer-free cars like Adam's are the only vehicles that function. Driving home, Adam encounters a storm tide of anger and fear as the region becomes paralyzed. Soon-as resources dwindle, crises mount, and chaos descends-he will see his suburban neighbourhood band together for protection. And Adam will understand that having a police captain for a mother and a retired government spy living next door are not just the facts of his life but the keys to his survival.
Adam has killed again. It had to be done, part of him knows that, but murder changes a person. It can certainly change a teenager who's already grown up too quickly, too harshly, in the wake of the catastrophic global blackout five months ago. In the name of safety and survival, Adam and his neighbours have turned their middle American suburban neighborhood into a fortress, defending against countless enemies. But what's lurking in the dark is a greater danger than ever before: somebody who wants to destroy the neighbourhood and Adam at any cost. Soon, the hunted will have to become the hunter...and Adam hates himself for what he will have to do. Because sometimes even the dark is not cover enough for things that would never happen in the light.
