Abstract:
Method, apparatus and system are described for converting received timestamps to a time-recording standard recognized by the receiving computing system. Embodiments of the invention generally include receiving data from an external device that includes a timestamp. If the received data is the first communication from the external device, creating a time base used for converting subsequently received timestamps to a recognized standard. Moreover, the system updates the time base if a counter failure at the external device is detected. When the external device transmits subsequent data, the time base is added to the subsequently received timestamps to convert the subsequent timestamps to a time-recording standard recognized by the computing system.
Abstract:
Techniques are described for managing states of an object using a finite-state machine. The states may be used to indicate whether an object has been added, removed, requested or updated. Embodiments of the invention generally include dividing a process into at least two threads where a first thread changes the state of the object while the second thread performs the processing of the data found in the object. While the second thread is processing the data, the first thread may receive additional updates and change the states of the objects to inform the second thread that it should process the additional updates when the second thread becomes idle.

Abstract:
A management system for managing computer resources assigned by a hypervisor to one or more logical partitions and/or one or more appliance partitions in a multi-user computer system receives login information from a new user logging into the computer system through a service interface (e.g. a hardware management console) or a non-service interface, builds a conflict list, and sends the conflict list for presentation to the new user. The new user is notified of any users that are logged into any part of the computer system that could conflict with the new user's actions. Such users may be logged into the computer system through service and/or non-service interfaces. In one embodiment, the new user can choose to continue logging in irrespective of any conflicts shown. After choosing to continue, the new user is preferably requested to input an end-time. This end-time may be displayed, in turn, to all subsequent users that log into any part of the computer system that could cause conflict. The management system is preferably a component of the hypervisor.

Abstract:
A method and system for online power management of a turbine engine is provided. The method includes operating an engine control system on a first bandwidth, filtering at least one data input from the engine control system to a second bandwidth, and receiving, by a power management system operating on the second bandwidth, the at least one filtered data input. The method also includes predicting an engine operating condition using the at least one filtered data input using a closed-loop engine model, determining an optimal engine power management based on the prediction, solving a constrained optimization for a desired optimization objective, and outputting the optimal engine power management to the engine control system.
Abstract:
Performance impact of a computing system component on a transient end-to-end system operation is estimated by profiling an overall characteristic for a transient end-to-end system operation, and simultaneously profiling a program code component for a second characteristic, thereby collecting a first pair of data points, repeating the operational period while introducing a known artificial delay into the program code component, and while profiling the overall performance characteristic for the system and for the program code component, thereby collecting pairs of data points for each repetition of the operational period for each of the artificial delays; curve fitting and analyzing intercepts of the collected data points to estimate the effect of the artificial delays in the program code component on the transient end-to-end system operation; and reporting the estimate correlated to potential optimal transient end-to-end system operation.

Abstract:
A presentation state is received from the presenting application. The presentation state may represent a current state of the local presentation. A request for the presentation state is received from the viewing application. In response to receiving the request for the presentation state, the presentation state is provided to the viewing application. A request for presentation data synchronized to the presentation state is received from the viewing application. In response to receiving the request for presentation data synchronized to the presentation state, the presentation file is transformed into the presentation data synchronized to the presentation state. The presentation data synchronized to the presentation state is provided to the viewing application. The viewing application may be operative to read the presentation data and to display a remote presentation in response to reading the presentation data.
Abstract:
A plasma-assisted waste gasification system and process for converting waste stream reaction residues into a clean synthesis gas (syngas) is disclosed. The feedstock is fed into a reactor roughly one-third from the bottom through the use of a feed mechanism. The reactor has three zones; a bottom zone where melting occurs, a middle zone where gasification takes place, and a top zone with integrated plasma torches to control the temperature and polish the syngas. The residence times in the three zones are selected to optimize the syngas composition and melted products. The syngas leaves the reactor and is partially quenched with relatively cooler synthesis gas. The partially quenched syngas is further cooled to recover heat for steam generation and/or preheating the waste stream to the reactor. The cold syngas is then processed to remove pollutants. The clean synthesis gas is combusted in power generation equipment to generate electricity, or converted to other fuels by chemical processes.
