Data Control Receiver Sender Receiver

Massively parallel multicomputers require a high-performance interconnection network. The physical channels which connect nodes in the network are the components that most commonly impose restrictions on the amount of data which can be communicated between nodes of the network. Several di erent schemes for maximizing the bandwidth of physical interconnection channels are examined. Conventional ...

Evaluating a Brazilian Metadata to Learning Objects to Web, Mobile and Digital Telivision Platforms

The paper presents an evaluation of a specification for metadata for learning objects and platforms developed for web, digital TV and mobile devices. For this, we present the two most widely used specifications, IEEE LOM and Dublin Core, and specification OBAA. The evaluation was divided into two stages, the first with expert and the second with professors. The results of the first are presente...

Topics 1. Main analog components for receivers-amplifiers-filters-mixers-oscillators 2. Receiver architectures and their properties-superheterodyne principle-direct conversion-DC offsets as a challenging problem-low IF, Weaver-effects of I/Q imbalance 3. Non-idealities and performance meatrics of the analog front-end modules-sensitivity, dynamic range-noise figure-intermodulation distortion, IP...

We describe the speciication of communication services, with special emphasis being placed on the use of the Temporal Logic of Actions (TLA) to describe the behaviours involved. We show how, starting from Message Sequence Charts, this temporal logic may be used to describe The Joint Viewing and Tele Operating Service (JVTOS) and its associated functions; and so lead on to the speciication of Qo...
