Applications of SLIM (Spectral Localization by Imaging) localization technique
… regions. These techniques are called localization techniques. Many techniques have been proposed for the localization of signals and some of them have been widely accepted for clinical applications. The ideal localization technique can be characterized as one which can provide spectrum …

Wireless relative localization
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-09-01 without embargo terms

Disorder-Free Localization
The venerable phenomena of Anderson localization, along with the more recent many-body localization (MBL), both depend crucially on the presence of disorder. Here we introduce a family of simple translationally invariant models of fermions locally coupled to spins, which have a disorder-free …

Scalable network localization
… first known real-time cooperative 3D wireless localization network. The Peregrine system comprises two major components: a hardware testbed; and a suite of distributed real-time algorithms to solve the highly interrelated problems of Node Prioritization, Node Activation, and Node Localization. …

Compressive super-localization
Localization accuracy is a fundamental quantity of an imaging system, since it often determines the performance (e.g. effective resolution, sensitivity) of the system. This thesis studies the influence on localization accuracy of finite sampling rate, number of samples, and noise in the data …

Acoustic source localization
Many technologies rely on underwater acoustics. Most of these applications are able to denoise Gaussian noise from the surrounding, but have trouble removing impulse like noises. One source of impulse-like noise is the snapping shrimps. The acoustic signals they emit from snapping their claws …

Autonomous Source Localization
This work discusses the algorithms and implementation of a multi-robot system for locating radioactive sources. The estimation algorithm presented in this work is able to fuse measurements collected by γ-ray spectrometers carried by an unmanned aerial and unmanned ground vehicle into a single …

Microbubble localization using multivariate gaussian fitting for super-resolution ultrasound localization microscopy
Super-resolution ultrasound localization microscopy is an advanced microvessel imaging modality. Multiple studies have proved its significant preclinical and clinical application potential. As an important step of the super-resolution ultrasound localization microscopy, current microbubble …

Factors influencing acoustical localization
… and that can also be used for psychacoustic localization measurements. The physical properties of HRTFs and the effect of spectral smoothing on the physical localization cues are investigated in another section. In order to investigate the perceptual robustness of the auditory system to …

LOCALIZATION TECHNIQUES FOR RENORMING
Renorming theory involves finding isomorphisms in order to improve the norm of a normed space X. This means to make the geometrical and topological properties of the unit ball of the given normed space as close as possible to those of the unit ball of a Hilbert space. In this work we study …

Nucleocytoplasmic Localization of MAPKs
… et al,1998). However the mechanisms of nuclear localization of MAPKs are still not fully understood clearly. Although most nucleocytoplasmic localization events require carrier proteins known as karyopherins (importins and exportins), ERK2 enters the nucleus of permeabilized cells even if these …

FMCW RFID backscatter localization
… has been an increasing interest in accurate localization and motion tracking using radio-frequency identification (RFID) tags. In this thesis, we explore a one-shot radio-frequency identification based localization and motion tracking approach with high accuracy, low latency, and whose cost …

Image-based Vehicle Localization
Localization is a crucial topic in navigation, especially in autonomous vehicles navigation. It is usually done by using a global positioning system (GPS) sensor. Even though there have been many studies of vehicle localization in recent years, most of them combine GPS sensor with other sensors to …

Localization and tracking of high-speed trains using compressed sensing based 5G localization algorithms
Complex systems are in place for the localization and tracking of High Speed Trains. These methods tend to perform poorly under certain conditions. Localization using 5G infrastructure has been considered as an alternative solution for the positioning of trains in previous studies. However, these …

Cross-domain network fault localization
Prior research has focused on intra-domain fault localization leaving the cross-domain problem largely unaddressed. Faults often have widespread effects, which if correlated, could significantly improve fault localization. For both competitive and security reasons, domain managers hesitate to share …

Light localization in biological media
… satisfying critical values of the Anderson localization transition. We find that the size of modes is smaller than specimen sizes and that the statistics of modes, decomposed from excitation at the gain-loss equilibrium, clearly differentiates silk and nacre from diffusive structures sharing …

Localization and Heegaard Floer Homology
In this thesis we use Seidel-Smith localization for Lagrangian Floer cohomology to study invariants of cyclic branched covers of three-manifolds and symmetry groups of knots by constructing localization spectral sequences in Heegaard Floer homology.

Source localization from voice signals
Indoor localization remains an open field of research, due to its utility and unresolved challenges. This thesis focuses on sound source localization using a small microphone array. Practically speaking, the aim is to allow smart voice assistants, such as Amazon Echo or Google Home, which possess a …
