Abstract: Embodiments are directed to automatically controlling network and service quality across datacenters. In one scenario, a computer system identifies portions of work that are to be performed within the datacenter. The computer system creates a request for change (request) in a change management system, where the change management system is configured to store and manage the implementation of requests within the datacenter. Then, upon implementation of the created request, the computer system polls the status of the request to determine whether the portions of work identified in the request can now be performed and, upon determining that the portions of work identified in the request can be performed, the computer system performs the portions of work according to the request. Performance of the specified work according to a request allows for workflows to be controlled based on the request.

Abstract: A steam turbine blade having an airfoil portion and root portion by which the blade is affixed to a rotor. The geometry of the blade airfoil is configured to minimize energy loss through the row of blades and reduce the weight of the airfoil. The airfoil has a leading edge and a trailing edge defining a chord therebetween. The chord is reduced linearly from the base of the airfoil to 50% of the airfoil height. However, the chord remains essentially constant from 50% of the airfoil height to the airfoil tip. The root is fir tree shaped and has four sets of tangs and grooves that are configured to minimize the stresses in the root.

Abstract: A steam turbine blade is provided in which the geometry of the blade airfoil is configured to reduce the weight of the blade while maintaining adequate thermodynamic performance. The blade has a high camber angle to increase its stiffness and an airfoil portion having pressure and suction surfaces. The curvature of the portion of the pressure surface between the base and 75% blade height has a point of inflection in an area adjacent the leading edge so that the curvature switches sign. The curvature upstream of the point of inflection is concave, while the curvature downstream of the point of inflection is convex.

The blade has a high camber angle to increase its stiffness and an airfoil portion having pressure and suction surfaces. The curvature of the portion of the pressure surface between 25% and 75% blade height has a point of inflection in an area adjacent the leading edge so that the curvature switches sign. The curvature upstream of the point of inflection is concave, while the curvature downstream of the point of inflection is convex.
