Linear system has a proportional slope, which gives the system a straight line. And, a non-linear system has a non-proportional slope, which is represented by a non-straight line (usually a curved one). Feel free to edit if you think this is not to the point.
It is an expression, not an equation and so cannot be proportional nor non-proportional.
Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.
Disproportional.If instead you're looking for the antonym of directly proportional, that would be inversely proportional.
Your question is incomplete... proportional to WHAT?
The disadvantages of majoritarian system and proportional election system included the use of proportional representation (PR) in voting.
A multiparty system is normally associated with proportional representation.
A multiparty system is normally associated with proportional representation.
The proportional tax system refers to the same percentage of tax regardless of the taxpayer's earnings. Proportional tax is also called as a flat tax.
A proportional system is an electoral system that ensures a close relationship between the popular vote a party receives and the number of candidate it receives.
This is related to control system and process control topic. Proportional integral is the mode that result from a combination of the proportional mode and the integral mode.
A hydraulic variable that describes the power provided by a hydraulic system. HHP is directly proportional to flow rate and pressure and inversely proportional to the efficiency of a system
Italy has a limited parliamentary government that is based on a proportional voting system.
The proportional integral and derivative control system or PID control system consists of proportionsl, derivative and integral elements which gives a very efficient process control.
Additional Member System which is a hybrid system (both majoritarian or 'normal' and proportional).It is a mixture of first past the post (same as the UK) and top-up seats which make the system more proportional.
It uses the principle of proportional control.A proportional control system is a type of linear feedback control system. Two classic mechanical examples are the toilet bowl float proportioning valve and the fly-ball governor. The proportional control system is more complex than an on-off control system like a thermostat, but simpler than a proportional-integral-derivative (PID) control system used in something like an automobile cruise control.
Proportional representation differ from the winner takes all system because in proportional representation, each faction gets some slots depending on some parameters whereas in the winner takes all system, the loser has nothing as the winner enjoys all.
