Optical System Contamination: Effects, Measurements and Control VII

Assessment of thruster induced contamination of critical surfaces is the important and necessary stage of International Space Station (ISS) component design. Plume contamination models aimed at the prediction of the spatial distribution of contaminant mass fluxes have been developed in the recent years for various ISS thrusters based on vacuum chamber and space flight experiments and empirical ...

Control Automation to Reduce Costs of Control

Much compliance effort concerns adherence to contracts. Controls are added to the business process to make sure the other party will fulfill his part of the contract. Controls have costs. In this paper we argue that fully automated controls help to lower control costs, because (i) they help to prevent misstatements (compliance by design) or (ii) they increase the quality of audit evidence and t...

Can managed care control costs?

The Hidden Costs of Control

We analyze the consequences of control on motivation in an experimental principalagent game, where the principal can control the agent by implementing a minimum performance requirement before the agent chooses a productive activity. Our results show that control entails hidden costs since most agents reduce their performance as a response to the principals controlling decision. Overall, the eff...

Optimal control of execution costs

We derive dynamic optimal trading strategies that minimize the expected cost of trading a large block of equity over a fixed time horizon. Specifically, given a fixed block SM of shares to be executed within a fixed finite number of periods 1, and given a price-impact function that yields the execution price of an individual trade as a function of the shares traded and market conditions, we obt...
