Planar Localization of Radio-Frequency or Acoustic Sources with Two Receivers

Proceedings, 2017
Spatial localization of emitting sources is especially interesting in different fields of application. The focus of an earthquake, the determination of cracks in solid structures or the position of bones inside a body are some examples of the use of ...

Localization Regions of Local Observables [PDF]

Communications in Mathematical Physics, 2000
Exploiting the properties of the Jost-Lehmann-Dyson representation, it is shown that in 1+2 or more spacetime dimensions, a nonempty smallest localization region can be associated with each local observable (except for the c-numbers) in a theory of local observables in the sense of Araki, Haag, and Kastler. Necessary and sufficient conditions are given

Metric-Based Few-Shot Learning With Triplet Selection for Adaptive GNSS Interference Classification

IEEE Journal of Indoor and Seamless Positioning and Navigation
Jamming devices pose a significant threat as they disrupt signals from the global navigation satellite system (GNSS) and thus compromise the accuracy and robustness of positioning systems. The detection of anomalies in frequency snapshots is essential to

Focusing Operators and Tracking Moving Wideband Sources

Journal of Telecommunications and Information Technology, 2016
In this paper, the localization of wideband source with an algorithm to track a moving source is investigated. To locate the wideband source, the estimation of two directions of arrival (DOA) of this source from two different arrays of sensors is used ...

Comparative study on the localization of adult Schistosoma mansoni worms in albino mice anesthetized with pentobarbital sodium, ether or chlorophorm Estudo comparativo sobre a localização de vermes adultos de Schistosoma mansoni em camundongos albinos anestesiados com pentobarbital sódico, éter ou clorofórmio

Revista do Instituto de Medicina Tropical de São Paulo, 1993
The effect of anesthetic drugs on the localization of adult worms in albino mice was compared. The animals with 56 days of infection were anesthetized with pentobarbital sodium, ether or chlorophorm.

Local DCPOs, Local CPOs and Local Completions

Electronic Notes in Theoretical Computer Science, 1999
AbstractWe use a subfamily of the Scott-closed sets of a poset to form a local completion of the poset. This is simultaneously a topological analogue of the ideal completion of a poset and a generalization of the sobrification of a topological space. After we show that our construction is the object level of a left adjoint to the forgetful functor from

Local perturbations perturb—exponentially–locally [PDF]

Journal of Mathematical Physics, 2015
We elaborate on the principle that for gapped quantum spin systems with local interaction, “local perturbations [in the Hamiltonian] perturb locally [the groundstate].” This principle was established by Bachmann et al. [Commun. Math. Phys. 309, 835–871 (2012)], relying on the “spectral flow technique” or “quasi-adiabatic continuation” [M. B.

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Development of an Evaluation Checklist for Localized Chinese Language Textbooks in Sri Lanka

Lingua Cultura, 2023
The research analyzed the limitations of existing Chinese language textbooks in Sri Lanka and proposed a tentative checklist for evaluating localized Chinese language textbooks. The discourse on the effectiveness of global textbooks in local contexts and

Local derivations and local automorphisms

Journal of Mathematical Analysis and Applications, 2004
It is shown that if \({\mathcal L}\) is a completely distributive commutative subspace lattice or a \({\mathcal J}\)-subspace lattice on a complex separable Hilbert space \(H\), then the space of all bounded derivations of \(\text{alg}({\mathcal L})\) is reflexive.
