use Dubai oil price is for reality of our oil importing environment. However, with this data, we might loss some additional information which can be obtained from WTI oil price data because what we want to measure is exchange rate change related to USD.
Although the empirical result cannot support our theoretical expectation, we did not give up the expectation because we do know the insufficien
production depends on the amounts of other factors that the firm plans to use. The demand for a factor is thus interdependent with the demand for other factors of production.

Relegated to low heat flux applications.
More total heat to remove than without a TEC.

HCCI is Homogeneous Charge Compression Ignition
HCCI engine concept combines aspects of SI and Diesel engines by compression igniting a pre-mixture of fuel and air.
No flame propagation or mixing controlled combustion – global auto-ignition of the charge .
Can use uniformly ultra-lean mixtures, giving low peak combustion temperatures, near zero NOx emissions.
Auto-ignition i
use an Avante for 12 years driving 15km, we can save 12 ton of CO2. This is same with the amount of CO2 that 30 year’s old fine tree can absorb.

4) The new performance management system
There are three objectives or attributes for their new system in the hope that they shift 2-million-hour investment from talking about the ratings to talking about people, from ascertaining the facts of performance to considering what they should do in resp
Furthermore, product development team would want to know how to enhance the products productivity. For example, in case the product is gas turbine engine, 1% increase in its efficiency of using fuel (such as coal), the cost savings could be millions of dollars since the longevity for such a product is usually over 50 years. With analytics teams help and IoT technology, the goal is achievable.
