In energy monitoring and targeting, a driving factor is something recurrent and measurable whose variation explains variation in energy consumption. The term independent variable is sometimes used as a synonym. One of the most common driving factors is the weather, expressed usually as heating or cooling degree days. In energy-intensive ...
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
One of the driving factors in modern gas turbine design is reducing emissions, and the combustor is the primary contributor to a gas turbine's emissions. Generally speaking, there are five major types of emissions from gas turbine engines: smoke, carbon dioxide (CO 2 ), carbon monoxide (CO), unburned hydrocarbons (UHC), and nitrogen oxides (NO x ).

The weighting factors are 0.43 for the cold start and transient phases together and 0.57 for the hot start phase. [ citation needed ] Though it was originally created as a reference point for fossil fuelled vehicles, the UDDS and thus the FTP-75, are also used to estimate the range in distance travelled by an electric vehicle in a single charge.
[A] cost driver is any factor which causes a change in the cost of an activity. [ citation needed ] However, a different meaning is assigned to the term by the business writer Michael Porter : "cost drivers are the structural determinants of the cost of an activity, reflecting any linkages or interrelationships that affect it".

This has been one of the key driving factors in international trade and globalization since the 1950s. [14] Bulk transport is common with cargo that can be handled roughly without deterioration; typical examples are ore, coal, cereals and petroleum. Because of the uniformity of the product, mechanical handling can allow enormous quantities to ...
