The Proportional Integral Derivate (PID) unit is the software core of most flight controllers. Its purpose is to minimize the error of a system by adjusting the process through the use of manipulated variables. The first PID controller was introduced as early as in 1939. As of yet‚ it is still the prevalent controller in process control [33][34][35]. Figure 9 shows the underlying control loop. Figure 9: Block diagram of a basic PID control loop.

See for example‚ Stilk v Myrick (1809) 2 Camp 317. However‚ the decision in Williams v Roffrey Bros & Nicholls (Contractors) [1991] 1QB1 impacts upon this traditional approach. Explain and justify the traditional approach of the courts and extent to which that approach is varied by the decision in Williams v Roffrey

Determining the Cost of Capital Can One Size Fit All? 1. Why do you think Larry Stone wants to estimate the firm’s hurdle rate? Is it justifiable to use the firm’s weighted average cost of capital as the divisional cost of capital? Please explain. Larry wants to estimate the firm’s hurdle rate because it would provide him with a standard with which to measure feasibility of future investment proposal. The firm had thus far been using a ‘gut feel’ approach and although most of
