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: 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: 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.

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: Control system and method for controlling an integrated gasification combined cycle (IGCC) plant are provided. The system may include a controller coupled to a dynamic model of the plant to process a prediction of plant performance and determine a control strategy for the IGCC plant over a time horizon subject to plant constraints. The control strategy may include control functionality to meet a tracking objective and control functionality to meet an optimization objective. The control strategy may be configured to prioritize the tracking objective over the optimization objective based on a coordinate transformation, such as an orthogonal or quasi-orthogonal projection. A plurality of plant control knobs may be set in accordance with the control strategy to generate a sequence of coordinated multivariable control inputs to meet the tracking objective and the optimization objective subject to the prioritization resulting from the coordinate transformation.

Abstract: A fiber gas sensor includes a fiber core with first and second refractive index periodic modulated grating structures having different amplitude modulation profiles positioned about the fiber core. A fiber cladding is positioned about the first and second refractive index periodic modulated grating structures. A sensing layer is positioned about the fiber cladding of one of the refractive index periodic modulated grating structures. The sensing layer includes a sensing material made of a Pd-based alloy, such as nano-PdOx, nano-Pd(x)Au(y)Ni(1-x-y) or nano-Pd/Au/WOx. The fiber gas sensor provides a measurement of localized, temperature-corrected gas concentration and composition from a combustion environment. A reflection-based or a transmission-based sensing system with an array of one or more fiber gas sensors is also described.
