Abstract: An improved system and method for characterizing application performance are disclosed. The system may comprise a profiling module and a web service module. The profiling module may be configured to prompt the user to select a public mode or a private mode and specify software and hardware targets for profiling. Test results from profiling may be combined with historical data obtained from a web service module providing access to a database of historical profiling test results to create recommendations for improving performance. The profiling module may upload the test-generated data in public mode to the web service module for use in future execution cycles or keep them private if in private mode.

Abstract: A method is provided for synchronizing clocks on a plurality of audio playback devices. The method includes receiving a broadcast/multicast acknowledgement packet from a synchronization agent at a first audio playback device of the plurality of audio playback devices. A first timestamp representing a time when the acknowledgement packet was received by the first audio playback device is recorded. A broadcast/multicast timestamp packet is received from a time server at the first audio playback device. The timestamp packet includes a second timestamp representing a time when the time server received the acknowledgement packet from the synchronization agent. A local clock time on the first audio playback device is updated based on the first timestamp and the second timestamp. The method enables clock synchronization among the plurality of audio playback devices for synchronized playback of streamed audio via the plurality of audio playback devices.

Abstract: BIODIESEL PRODUCTION PROCESS USING VEGETAL OILS OR ANIMAL FAT AND INDUCTION THROUGH MICROWAVES affording fatty acid monoalkylesters from the microwave induced (2.450 or 915 MHz) acid or base catalyzed transesterification/esterification reaction of vegetable oils or animal fats or fatty acid, through a microwaves generator coupled to the reaction cavity. The process occurs by dissipating the microwaves' energy using polarization mechanisms and electric conductivity generated in the reaction medium due to the high dielectric permittivity, propitiated by the catalyst.
