This paper deals with fault detection methods taking model uncertainties into account. It focuses on dynamic and structured uncertain models, where parameter uncertainties are described by bounded variables. In order to de-couple residuals from unknown physical variables, a parity space approach is proposed, where the parity matrix depends on uncertain parameters. In this way, residuals are not...

In order to achieve high reliability in disk array systems, two new schemes using dual parity placement, called DH1 (diagonal±horizontal) and DH2 schemes, are presented. Both DH schemes can tolerate up to two disk failures by using two types of parity information placed in the diagonal and the horizontal directions, respectively, in a matrix of disk partitions. DH1 scheme can reduce the occurre...

With the first measurements of the branching ratios and the direct CP asymmetries of B s → K − K + , K − π + decays by the CDF collaboration, we constrain the relevant parameter space of the Minimal Supersymmetric Standard Model with R-parity violation. Using the constrained R-parity violating couplings, we further examine their possible effects in B s → K − * π + , K (*)− ρ + and K (*)± K (*)∓...

An n-bit string is encoded as a sequence of non-orthogonal quantum states. The parity bit of that n-bit string is described by one of two density matrices, ρ (n) 0 and ρ (n) 1 , both in a Hilbert space of dimension 2 n. In order to derive the parity bit the receiver must distinguish between the two density matrices, e.g., in terms of optimal mutual information. In this paper we find the measure...

We consider parity games, a special form of two-player infiniteduration games on numerically labelled graphs, whose winning condition requires that the maximal value of a label occurring infinitely often during a play be of some specific parity. The problem has a rather intriguing status from a complexity theoretic viewpoint, since it belongs to the class UPTime ∩ CoUPTime, and still open is th...

We present the novel embodiment of a photonic qubit that makes use of one continuous spatial degree of freedom of a single photon and relies on the parity of the photon's transverse spatial distribution. Using optical spontaneous parametric down-conversion to produce photon pairs, we demonstrate the controlled generation of entangled-photon states in this new space. Specifically, two Bell state...

We study unconventional decays of the top-quark and the top-squark in the framework of SUSY models with broken R-parity. The model under study is the MSSM with an additional bilinear term that breaks R-parity. In this model the top-squark behaves similar to a third generation leptoquark. We demonstrate that existing Tevatron data on the top give rise to restrictions on the SUSY parameter space....

We show that a vapor of multilevel atoms driven by far-off-resonant laser beams, with the possibility of interference of two Raman resonances, is highly efficient for creating parity-time symmetric profiles of the probe-field refractive index, whose real part is symmetric and imaginary part is antisymmetric in space. The spatial modulation of the probe-field susceptibility is achieved by a prop...

One of the important features of the littlest Higgs model with T-parity, called the LHT model, is that it introduces the mirror fermions, which are the T-parity partners of the standard model fermions. In this paper, we discuss production of the mirror quark associated with mirror neutrino via eγ and ep collisions. We find that, in wide range of the parameter space, the mirror quark can be copi...

We first present a machine that decides parity. The machine scans the input from left to right. After looking at each bit, the machine remembers whether the number of 1’s seen so far is odd or even. Initially, the number is 0 and therefore even. The machine then toggles between even and odd for each 1 seen in the input, and does nothing for each 0. This even/odd toggle can be incorporated into ...
