  • Other – Ideas and concepts that do not fit within the other categories.

 

2. Make $200 registration fee out to the INCAnaut Challenge.

 

What will I get when I register?

INCA modeling kit worth $400 to use and experiment for up to 4 months.

 

What do I have to do to complete the challenge?

 

  1. Keep a lab book – must have at least 10 pages of records.
  2. Make a poster displaying your ideas
  3. Make a video presentation or present at one of our events (10 to 15 minutes long).
  4. Write an essay explaining why your concept could be created in the future (400 to 500 words and must have at least 5 references).

 

How long do I have to complete the challenge?

A total of 4 months from the day you receive the INCA modeling kits.

 

What happens if I don’t meet the deadline?

Then your entry fee will not be reimbursed.

 

What happens if I complete the challenge?

The INCA modeling kit is returned and all work is submitted to the INCAnaut Challenge (must be postmarked by the 4 month deadline).

You receive a check for 250 dollars; which includes a reimbursement of your registration fee and 50 dollars for completing the challenge!

 

What happens if some of the pieces I send back are damaged or painted?

The cost of the damaged pieces is subtracted from the check we send you when you complete the challenge.

 

Can I participate more than once?

Yes, but you have to submit a proposal of your new design for approval before you can enter a second time because of the limited supply of models.

 

Important Info

  • Team meeting reports, brain storming session ideas, and other notes need to be kept in a black and white composition notebook which must be submitted.
  • All teams that cannot make it to the presentation event need to submit video presentations.
  • Each of the team members must actively participate in the design assembly, testing, promotion, and/or support in the team’s final presentation.

 

Tips for Entrants

  • What problem does your design idea solve?
  • What are the potential benefits?
  • How would this idea be applied?
  • How is your idea novel or an improvement on what is currently available in the marketplace?
  • Why would we need/want the design?
  • What is the market potential?
  • How does your design work?
  • How would your product be manufactured?

 

The best design ideas will:

  • Improve quality of life
  • Automate tedious tasks
  • Prevent or reduce injuries
  • Improve public safety and security

WHAT is YOUR COMPUTERS MTBF?

Explained. You actually  DO need this.

 

Failure rate: What is yours?

 

Failure rate:
The frequency with which an engineered system or component fails, expressed for example in failures per hour.
 It is often denoted by the Greek letter λ (lambda) and is important in reliability engineering.

The failure rate of a system usually depends on time, with the rate varying over the life cycle of the system.

For example, an automobile’s failure rate in its fifth year of service may be many times greater than its failure rate during its first year of service.

( EXPECT is the operative word- LOL)

One does not EXPECTto replace an exhaust pipe, overhaul the brakes, or have major transmission problems in a new vehicle. Yes- BUT…

In practice, the mean time between failures (MTBF, 1/λ) is often used instead of the failure rate. This is valid if the failure rate is constant (general agreement in some reliability standards (Military and Aerospace) – part of the flat region of the Reliability bathtub curve , also called the “useful life period”.

The MTBF is an important system parameter in systems where failure rate needs to be managed, in particular for safety systems.

 The MTBF appears frequently in the engineering design requirements, and governs frequency of required system maintenance and inspections.

In special processes called renewal processes, where the time to recover from failure can be neglected and the likelihood of failure remains constant with respect to time, the failure rate is simply the multiplicative inverse of the MTBF (1/λ).

A similar ratio used in the transport industries, especially in railways and trucking is ‘mean distance between failures’, a variation which attempts to correlate actual loaded distances to similar reliability needs and practices.

Failure rates are REALLY important factors in the computer industry.>

Just ask Gateway.

Example of : How often your Sweet little Computer MIGHT Crash and Burn…

Suppose it is desired to estimate the failure rate of a certain component. A test can be performed to estimate its failure rate. Ten identical components are each tested until they either fail or reach 1000 hours, at which time the test is terminated for that component. (The level of statistical confidence is not considered in this example.) The results are as follows:

Estimated failure rate is

\frac{6\text{ failures}}{7502\text{ hours}} = 0.0007998 \frac\text{failures}\text{hour} = 799.8 \times 10^{-6} \frac\text{failures}\text{hour},

or 799.8 failures for every million hours of operation

 Ask your dentist or dental hygenist ( I know- I know you hate going to the dentist- eye roll) and REMEMBER- your Dentist  MISSES YOU…

Ask your Dentist or hygenist  if they ever have a sore or tired back at the end of the day.
I am SURE they do have tired and sore backs,

 AND and they will be shocked and delighted that you even asked about them.

It’s not ALL just about you,bunky..

 ANTERIOREST.

This is dental engineering at its best.
I just found out about this product.

And I really  am very willing to state I had never thought about the physical consequences of the  provider of your care- standing/eleaning  over a chair 8 hours a day. .
Much more to come.

View and have pity on your poor dentist.He/she may be in pain too. http://www.youtube.com/watch?v=9GkbSC7OZNg
