Uniformly redundant arrays (URA) have autocorrelation functions with perfectly flat sidelobes. The URA combines the high-transmission characteristics of the random array with the flat sidelobe advantage of the nonredundant pinhole arrays. A general expression for the signal-to-noise ratio (SNR) has been developed for the URA as a function of the type of object being imaged and the design parame...

In this paper we investigate threshold based networks performing 2 1 addition using redundant binary operand representations. In particular we concern with establishing the networks with the smallest network depth assuming small weight and fan-in values. First we propose a depth-4 implementation and we show that the 2 1 addition can be computed by a threshold network with the size in the order ...

Coded aperture imaging uses many pinholes to increase the SNR for intrinsically weak sources when the radiation can be neither reflected nor refracted. Effectively, the signal is multiplexed onto an image and then decoded, often by computer, to form a reconstructed image. We derive the modulation transfer function (MTF) of such a system employing uniformly redundant arrays (URA). We show that t...

We present a constructive proof in Bishop’s style of Lebesgue’s dominated convergence theorem in the abstract setting of ordered uniform spaces. The proof generalises to this setting a classical proof in the framework of uniform lattices presented by Hans Weber in “Uniform Lattices II: Order Continuity and Exhaustivity”, in Annali di Matematica Pura ed Applicata (IV), Vol. CLXV (1993). 1. Both ...

In August 1998, an interviewer for an Indonesian news weekly asked Amien Rais, a major figure in national Islamic politics and founder of the National Mandate Party (Partai Amanat Nasional), why he had altered the name of the party from the originally proposed Partai Amanat Bangsa. He replied, “We chose Partai Amanat Nasional because it would be better translated into English as National Mandat...
