A cutting insert for a ball nose end mill includes a body including two opposed substantially flat retention surfaces. The clutch is pressure-medium actuated and includes an actuating piston acting on the release unit to engage and disengage the clutch, and a pressure chamber which is delimited at one side by at least one part of the actuating piston and at the other side by at least one part of a clamping piston. The computer system converts the coordinated security policies to firewall rule configuration for each of the managed network devices affected. It is then determined whether yield of the target module is acceptable, and if the yield is not acceptable, a design which includes the target module is adjusted in accordance with the sensitivities to adjust the yield. A control module is coupled to the light source to control the light source to emit light at least four spaced-apart light wavelengths, and a monitoring module is coupled to the light detector to receive the output signal and compute a measure of tissue oxygenation using the light detector output signal.
