As Orthogonal Frequency Division Multiplexing (OFDM) becomes more prevalent in new leading-edge data rate systems processing spectral bandwidths beyond 1 GHz, the required operating speed of the baseband signal processing, specifically the Analogto-Digital Converter (ADC) and Fast Fourier Transform (FFT) processor, presents significant circuit design challenges and consumes considerable power. ...

The communication blocking protocols of stopping or repeating a service in non-exponential queueing networks with blocking are shown to be equivalent under a partial balance condition. Examples both with a reversible and nonreversible routing are given.

A blocking semioval S in a projective plane of order q is a set of points such that every line meets S in at least one point (the blocking property), and every point of S lies on a unique tangent line (the semioval property). The set of points on the sides of a triangle, excluding the vertices, is a blocking semioval in any projective plane of order q > 2, and has size 3q − 3. The size of a blo...

In today’s ubiquitous multiprocessor environment parallel programming becomes an important tool to reap the maximum gain. But the traditional lock-based parallel programming model is not attracting average programmers as the level of expertise needed is very high. A program can be trapped in deadlock and livelock by unconscious locking of shared resources. Furthermore, a lock-based parallel pro...
