Using the parity-space approach, a residual is formed by applying a projection to a batch of observed data and this is a well established approach to fault detection. Based on a stochastic state space model, the parity-space residual can be put into a stochastic framework where conventional hypothesis tests apply. In an on-line application, the batch of data corresponds to a sliding window and ...

A manifestly gauge invariant formulation of the coupling of the Maxwell theory with an Einstein Cartan geometry is given, where the space time torsion originates from a massless Kalb-Ramond field augmented by suitable U(1) Chern Simons terms. We focus on the situation where the torsion violates parity, and relate it to earlier proposals for gravitational parity violation. Electronic address: pa...

In this paper we examine the behaviour of the uniform crossover and point mutation GP operators 12] on the even-n-parity problem for n = 3; 4; 6 and present a novel representation of function nodes, designed to allow the search operators to make smaller movements around the solution space. Using this representation, performance on the even-6-parity problem is improved by three orders of magnitu...

Parity is ubiquitous, but not always identified as a simplifying tool for computations. Using parity, having in mind the example of the bosonic/fermionic Fock space, and the framework of Z2-graded (super) algebra, we clarify relationships between the different definitions of supermanifolds proposed by various people. In addition, we work with four complexes allowing an invariant definition of d...

We report the first experimental violation of Bell's inequality in the spatial domain using the Einstein-Podolsky-Rosen state. Two-photon states generated via optical spontaneous parametric down-conversion are shown to be entangled in the parity of their one-dimensional transverse spatial profile. Superpositions of Bell states are prepared by manipulation of the optical pump's transverse spatia...

The proton-proton parity-violating longitudinal asymmetry is calculated in the lab-energy range 0–350 MeV, using a number of different, latest-generation strong-interaction potentials–Argonne v18, Bonn-2000, and Nijmegen-I–in combination with a weak-interaction potential consisting of ρand ω-meson exchanges–the model known as DDH. The complete scattering problem in the presence of parity-conser...

In this paper we develop a new algorithm for deciding the winner in parity games, and hence also for the modal μ-calculus model checking. The design and analysis of the algorithm is based on a notion of game progress measures: they are witnesses for winning strategies in parity games. We characterize game progress measures as pre-fixed points of certain monotone operators on a complete lattice....

Due to recent advances in CPU and memory system performance, I/O systems are increasingly limiting the performance of modern computer systems. Redundant Arrays of Inexpensive Disks (RAID) have been proposed by Patterson et al. [1] to meet the impending I/O crisis. RAIDs substitute many small inexpensive disks for a few large expensive disks to provide higher performance (both transfer rate and ...
