Engineers like Excel for the simplicity in doing quick calculations and developing spreadsheets. But forget about it when it comes to managing those calculations or gaining any insight behind the numbers—two tasks that the software application Mathcad does very well, though its learning curve is somewhat steeper. But that ability to capture the thinking process of engineers is becoming increasingly important to some companies who are looking for ways to capture the engineering calculations in large projects and document the inputs, assumptions, and methods behind them, says Allen Razdow, senior vice president of products and services and cofounder of Mathsoft. "Companies are beginning to realize that a calculation is not an island, and that it's important to know where a number came from and what thinking went into it." To wit, his company just landed a major contract with Lockheed Martin, who is adopting Mathcad as a standard design tool for all structural calculations for the F-35 Joint Strike Fighter Project, the largest military contract in history. With a budget of $4B, there's bound to be plenty of number crunching. New features of Mathcad, such as the ability to deploy content over a web browser, is bound to make that process a bit more manageable.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
