An optical communication link is proposed for high speed point-to-point data transmission. The incorporates both fiber and wireless technologies. Kramer-Kronig coherent detection used due to its component implementation simplicity. Spatial multiplexing, via a multi-core followed by link, wavelength division multiplexing allow the efficient exploitation of all available degrees freedom. signal-t...

We present a flow analysis technique for detecting unreachable states and actions in concurrent systems. It is an enhancement of the approach by Cheung and Kramer. Each process of a concurrent system is modeled as a finite state machine, whose states represent process execution states and whose transitions are labeled by actions. We construct dependency sets incrementally and eliminate spurious...

Recently many studies on evolutionary algorithms using real encoding have been done. They include ant colony optimization (Socha & Dorigo, 2008), artificial bee colony algorithm (Akay & Karaboga, 2010; Kang et al., 2011), evolution strategies (ES) (Beyer, 2001), differential evolution (Das & Suganthan, 2011; Dasgupta et al., 2009; Kukkonen & Lampinen, 2004; 2005; Mezura-Montes et al., 2010; Nom...

Consider the following question: Does there exist a three-manifold M for which, given any riemannian metric on M there is an area bound for embedded minimal spheres? We answer this question negatively, and, in fact, find an open set of metrics for which this question is false. This generalizes similar results for surfaces of positive genus shown by W. Minicozzi, T. Colding and B. Dean. In addit...

In this paper, conservative simultaneous confidence intervals for multiple comparisons among mean vectors in multivariate normal distributions are considered. Some properties of the multivariate Tukey-Kramer type procedures for pairwise comparisons and for comparisons with a control are presented. The upper bounds for the conservativeness of the procedures are discussed. Finally, numerical resu...

Given a signal space of functions on the real line, a time-warped signal space consists of all signals that can be formed by composition of signals in the original space with an invertible real-valued function. Clark's theorem shows that signals formed by warping ban-dlimited signals admit formulae for reconstruction from samples. This paper considers time warping of more general signal spaces ...
