How do we use ubiquitous computing?
The same way as we use products without it. However products with it can also: be controlled remotely, report problems and failures directly back to the manufacturer making under warranty repairs automatic, etc. Unfortunately there is also a significant chance of hackers attacking them that clearly did not exist with products lacking this feature!
What is the likelihood of an oil-filled transformer exploding as a percentage?
? This cannot be easily quantified. transformers normally fail due to excessive through fault current. This does not mean that all transformers that fail explode - most do not, for good reason. An exploding transformer is a danger to anyone in the area. Some oil filled transformers are huge (several hundred tons). Protective devices usually operate fast enough to keep catastrophic failures like you're looking for from happening. If the protection fails to clear faults fast enough, can happen. So the percentage of failures really does not have to do with the transformer (oil filled, gas, whatever kind of transformer) as much as with the protection implemented for that transformer. I've seen two large transformer failures; neither resulted in an explosion. I've also seen an oil filled breaker fail (as a result of incorrect protection), and it did explode. It totalled a vehicle several hundred feet away. So... I'll say "1 in a million" or .0001% would probably be a good, totally unqaulifiable answer.
What are the classes of failures in a tranformer?
Biggest problems are the windings either having an open circuit or a short circuit.
What is the cause of fluctuation in amps and pf in a 6000hp syncrhonous motor?
When the line voltages of a polyphase motor induction motor are not equal, unbalanced currents in the stator windings will result. A small percentage voltage unbalance will result in a much larger percentage current unbalance. Consequently, the temperature rise of the motor operating at a particular load and percentage voltage unbalance will be greater than the motor operating under the same conditions with balanced voltages. NEMA Standards MG 1-1998, 12.46 recommends against operating a motor with a voltage unbalance greater than 1%. This will increase operating temperature, vibration, nuisance trips and failures.
Are nuclear reactors dangerous?
Yes, but there are risks associated with every type of power plant. Its simply a matter of understanding those risks and dealing with them. In the case of nuclear reactors, we design whats known as "defense in depth", so that any hypothetical failure, or sequence of failures, including some improbable failures, can be handled.
What has the author R D Leach written?

What is the percentage of transmission failures in the 2002 dodge neon?
not a common problem
What happens when you put one gallon of diesel in the hydraulic tank on cat forklift?
You'll thin out the oil more than it already is which can lead to internal damage or even catastrophic failures of moving hydraulic parts, pumps, cylinders etc.
When was the quote Ninety-nine percent of failures come from people who have the habit of making excuses stated?
Ninety-nine percent of failures come from people who have the habit of making excuses. This quote is attributed to George Washington Carver in the late 19th century.
Who wrote if your greatest glory is not in never falling but in rising when you fall?
Nelson Mandela is often attributed to this quote. It emphasizes the value of resilience and the ability to learn and grow from failures.
What are the worst failures?

When was Various Failures created?
Various Failures was created in 1999.
How many failures did the wright brothers make?
They had a lot of failures!
Successes and failures?
Successes and failures are considered to be part of development. In most cases, there will a number of failures before success is achieved.

Who said fail early and fail often?
The concept of "fail early and fail often" is often attributed to researcher and author Samuel Beckett. This phrase emphasizes the importance of learning from failures and using them as stepping stones towards success.
When was The Failures created?
The Failure was created in 1917.
