Radio-frequency (RF) ranging can be an important aid to an integrated navigation system, providing a key element to updating location information when GNSS systems are unavailable, blocked, or otherwise denied. The majority of the recent literature on RF ranging aids has focused on ultra wideband (UWB) ranging methods, due to the increase in ranging precision that comes with increasing RF bandw...

Kernel Based Regression (KBR) minimizes a convex risk over a possibly infinite dimensional reproducing kernel Hilbert space. Recently it was shown that KBR with a least squares loss function may have some undesirable properties from a robustness point of view: even very small amounts of outliers can dramatically affect the estimates. KBR with other loss functions is more robust, but often gives...

The use of KBr pellets as an interference-free matrix for performing time-resolved infrared (TR-IR) measurements on samples in their crystalline state is described and demonstrated. Step-scan Fourier transform infrared time-resolved spectroscopy (S2FT-IR TRS) is used to measure the infrared (IR) absorption difference ( D A, excited state minus ground state) spectra of the long-lived chargetrans...

This paper presents some theoretical convergence characteristics of Keep-Best Reproduction (KBR), a selection strategy for genetic algorithms (GAs). We have previously introduced KBR and reported encouraging results in the traveling salesman domain (Wie98a) where KBR was compared with the standard replacement strategy of replacing the two parents by their two children (STDS). Here we demonstrat...

In this paper, we present a robust and secure algorithm for watermarking, the watermark is first transformed into the frequency domain using the discrete wavelet transform (DWT). Then the entire DWT coefficient except the LL (Band) discarded, these coefficients are permuted and encrypted by specific mixing. The encrypted coefficients are inserted into the most significant spectral components of...

a number of complexes in the series (cu ll'),, where l = [(ch,),c-co-ch-coc( ch,),]-i and l'= 3-(me) c6h,0-, 2,6-(di-me)c6h30-, 4-(oh)c6h?o-, 3- (f) c6h,0-, 4-(br)c6h40-a, nd 3,s-(dl-me)c6h30h- ave been prepared and theu magnetic and optical properties determined. in chloroform, the complexes exhibit two bands in the visible and near uv regions. all complexes show room temperature mag...

By combining exotic band dispersion with nontrivial band topology, an interesting type of band structure, namely, the flat Chern band, has recently been proposed to spawn high-temperature fractional quantum Hall states. Despite the proposal of several theoretical lattice models, however, it remains doubtful whether such a "romance of flatland" could exist in a real material. Here, we present a ...

Three-body AAB model for the NNK(snn = 0) kaonic cluster is considered based on configuration space Faddeev equations. Within a singlechannel approach, difference between masses of nucleons and kaons charge independence breaking nucleon-nucleon interaction are taken into consideration. We definite particle configurations in system according to pair potentials. There two sets configurations, ppK...
