We consider linear precoding and decoding in the downlink of a multiuser multiple-input, multipleoutput (MIMO) system, wherein each user may receive more than one data stream. We ...

We present an adaptive load shedding approach for windowed stream joins. In contrast to the conventional approach of dropping tuples from the input streams, we explore the concept ...
The task of designing and implementing a compiler can be a difficult and error-prone process. In this paper, we present proach based on the use of higher-order abstract syntax and...
