Part I:

As we have noted, there are many different places you can turn to develop your own applications. We don t have the space to cover each and every development platform, so we ll walk you through the development steps with three different, popular platforms: the Google App Engine, Salesforce.com, and Microsoft Azure.

gain degeneration in this circuit. The higher the voltage across RE, the more temperature stable the amplifier, but the more power will be wasted in RE because of VE2/RE, as well as the decreased AC signal gain if RE is not bypassed by a low-reactance capacitor. Standard values of VE for most HF (amateur band) designs are between 2 to 4 V to stabilize VBE. However, UHF amplifiers and above will try to completely avoid emitter resistors. One voltage source is also supplying all of the biasing required for the basebiased emitter feedback circuit for the proper operation of the NPN transistor, since RB and RC are accurately allocating the suitable voltages to both the collector and the base with the appropriate polarity through a single power supply. This is due to the following: The collector resistor, the collector-emitter junction, and the emitter resistor are all in series with each other, and share VCC s voltage. Thus, the collector-to-emitter voltage is equal to VCC, minus the voltage drop across the collector and emitter resistors of RC and RE, forcing the collector to be correctly reverse biased. The base circuit is also properly forward biased by the following action: The base resistor, the emitter-base junction, and the emitter resistor are in all series and share the VCC power supply s voltage. So, the voltage drop across RB will be equal to VCC minus the normal emitter-base voltage drop of 0.7 V and the voltage drop across the emitter resistor. And since the voltage drop across the emitter-base and the emitter resistor are kept relatively low, most of the power supply s voltage is dropped across RB, properly forward biasing the transistor s base. In fact, the base current, and thus the collector current, can be increased by decreasing the value of the base resistor. However, because of the inclusion of the emitter resistor

channels are tied together to provide aggregate bandwidth of N 64 kbps. The wideband signal is spread across several timeslots, so it is important that these are received in the right sequence at the far end; otherwise the payload will not be reconstructed properly.

Uploads to the DCS are initiated by the individual servers in the farm based on the Upload time. The following sequence of events occurs for each Presentation Server with Resource Manager enabled when the Upload time is met each day. 1. Presentation Server closes the current summary file and begins a new file. 2. Presentation Server sends a notification to the DCS stating it has a summary file to be uploaded. One notification per summary file is ready to be uploaded. 3. DCS maintains a list of all notifications. 4. DCS requests files to be copied to it. The number of concurrent uploads is limited to reduce congestion. 5. When files are available on the DCS, the import starts. Imports are limited to a maximum concurrent amount. 6. For each file being imported, a new file is uploaded, so ten files are either copying or ready to be imported. 7. When the import succeeds, a message is sent to the originating host, informing it that the summary file can be safely deleted. The file is also deleted from the DCS. 8. This continues until there are no further summary files to be uploaded or imported.
