Abstract: Methods and apparatus, including systems and computer program products, for a services architecture design that provides enterprise services having accounting functionality at the level of an enterprise application. The design includes a set of service operations, process components, and optionally deployment units. Suitable business objects are also described.

Abstract: Systems and techniques to manage and represent development processes. In general, in one implementation, the technique includes a method for managing a software development process. The method includes providing a cookbook describing tasks in a framework of the development process and managing performance of the development process with the cookbook. A first task description identifies an activity in the development process, an input for performance of the activity, an output consequential of performance of the activity, and instructions for performance of the activity.

Abstract: A circuit arrangement for scanning optical recording carriers comprises a scanning device, a first control loop for focusing a light beam of the scanning device directed onto the information plane of the recording carrier and a second control loop for guiding the light beam on an information track. The first control loop exhibits a first control amplifier which is supplied with focus error signals and the second control loop exhibits a second control amplifier which is supplied with track error signals. The control amplifiers drive actuators which mechanically guide the scanning device. To compensate for the temperature response of the control gain, controlling elements connected to temperature sensors via gain controllers are arranged in the first and second control loop, which controlling elements temperature-dependently change the gains.
