Contingency - When estimating the cost for a project, product or other item or investment, there is always uncertainty as to the precise content of all items in the estimate, how work will be performed, what work conditions will be like when the project is executed and so on.
An arbitrator is one who delivers a fair judgment to resolve a dispute. The arbitrator's decision may or may not be favorable to one or more parties involved; however, the arbitrator is a neutral third party chosen by the disputing parties in lieu of litigating in court.
An integrator may also be a systems integrator. An integrator is a component whose output signal is the time integral of its input signal. It is the continuous analog of a counter, cumulating the input into an output.Integration is an important part of many engineering and scientific calculations.Mechanical integrators are used in such applications as metering of water flow or electric power.n integrator will have a low pass filtering effect but when given an offset it will accumulate a value building it until it reaches a limit of the system or overflows. A voltage integrator is an electronic device performing a time integration of an electric voltage, thus measuring the total volt-second product.
