Random testing can only pick up systemic faults within an entire product line not random ones.
Statistics is your friend in this case. Random testing should show a large standard deviation (assuming they test to failure). You should then be able to calculate the probability of failure.
This may not be so random.
You can test random struts, but you can't test ALL struts or you're left with no struts. Sounds like they didn't test the right ones is all.
Who says you have to test them to failure? Just test them for the designed load.
But... Ford's system IS Toyota based... they licensed the HSD system from Toyota.
The details are what's important. Did they license the technology, or buy it from Toyota Who was responsible for the software, calibration, and integration?
Wikipedia says Ford licensed the technology but developed it themselves.
They’re great. I’ve never seen a cell go bad or a module. I’ve had to crack a few open (only twice) and put new cooling fans but other than that they are perfect. The camry and prius burn battery packs like crazy.
5. In order to have a chance to regulate the temperature well - and not keep cycling through blasts of heat and cooling - they'll need multiple temp probes, and an awareness of the outside temp and humidity as well, since ceramic insulation or no, the external environment will play a huge factor.
If your PID controller is cycling like that something is seriously wrong. Even a poorly tuned controller should eventually stabilize, unless the gains are way out from where they should be. The controller should be easily capable of overcoming fluctuations in ambient temperature, even in New England.
NASA had a dependable spacecraft. Couldn't they have improved the Space Shuttle?
The Space Shuttle was far from dependable. Worst of all, when it failed, it failed catastrophically. The issues were due to its very basic design. One example being solid rocket boosters operating along side the crewed spacecraft. Once the boosters are lit, there is no turning back. They can't be turned off, and they can't be jettisoned.
The issues were much worse prior to Challenger. Structural changes were made to the stack to allow the spacecraft to continue to fly with main engine failures. From my understanding, the shuttles' main engines were capable of propelling the craft to orbit, but not the fuel. The solid rocket boosters were needed to lift that big orange fuel tank. If the shuttle's engines went out, the connections between the shuttle, tank, and solid rockets were not strong enough, and the whole thing would break apart.
Right up until the point you said "baseball." In the title.
It's actually more interesting than you might think. The Houston Astro's have been a poor performing team up until very recently. They hired a new manager that uses data driven techniques similar to those used in the book/movie Moneyball. Since they hired him, the team's performance has improved. There is talk of him having some "proprietary information" that has boosted the team's performance.
The game of baseball has evolved more rapidly in the past ten years than it has in the previous 100. It is more data driven than ever. I wouldn't be surprised if teams are building computer models of performance that they then try to optimize.
... you'd think the A400M engine software would have a *baked in* "go home without crashing" dataset.
From how I read the article, it does have a default dataset that it switches to when it detects a problem. From TFA:
The automatic response is to hunker down and prevent what would usually be a single engine problem causing more damage.
Limiting the speed of a ground vehicle is safe. However, limiting the speed of an aircraft causes a crash. It sounds like they need to reevaluate their "limp home" calibration, as we call it in the industry.
But in order to hire H1Bs, I thought a company needs to demonstrate that they have advertised locally for the positions and can't find any sufficiently qualified people to take them.
Companies often get around this requirement by writing the position's requirements to specifically match the H1B candidate's resume. The odds of getting another candidate with the exact same skill set are astronomical. I have witnessed this practice in person.
There's a poster downthread who talks about how legal laws will bow to economic forces and that this cannot be stopped. That poster is right--this process CANNOT be stopped.
I can't disagree with this statement more. Business is about competition. Companies play these games because if they don't, their competitors will. If you make it illegal, and enforce it, the competitive landscape remains level. Everyone's costs go up. Sure, the costs will get passed on to the consumer. However, the company won't lose business, or market share won't be impacted.
The only downside is the risk of imported "goods" (I use this term loosely as it could be a service as well) from a competitor based overseas. We saw this in the manufacturing sector in the past. However, I'm not sure that would apply to other fields.
