Map-Aware Models for Indoor Wireless Localization Systems: An Experimental Study

open access: yes, 2014
The accuracy of indoor wireless localization systems can be substantially enhanced by map-awareness, i.e., by the knowledge of the map of the environment in which localization signals are acquired.

Partial Discharge Localisation in Power Transformer by UHF Technique

open access: yesHigh Voltage, Volume 10, Issue 5, Page 1314-1323, October 2025.
ABSTRACT This article deals with the methods of finding partial discharge (PD) location in power transformers using ultra high frequency (UHF) measurements. The UHF technique utilises two methods to find the PD location, that is, the shortest path method and hyperbolic method.

Combined Evidence Reveals the Origin of a Rapid Range Expansion Despite Retained Genetic Diversity and a Weak Founder Effect

open access: yesMolecular Ecology, Volume 34, Issue 19, October 2025.
ABSTRACT Many species are currently experiencing range shifts in response to changing environmental conditions with potentially serious genetic consequences. Repeated founder events and strong genetic drift are expected to erode genetic variation at the range front, reducing adaptive potential and slowing or even halting the expansion.

Source localization and denoising: a perspective from the TDOA space

open access: yes, 2016
In this manuscript, we formulate the problem of denoising Time Differences of Arrival (TDOAs) in the TDOA space, i.e. the Euclidean space spanned by TDOA measurements.

Determining the Direction of Radio Wave Reception for Maximum Radiation Using Genetic Algorithm and RF to DC Conversion Efficiency Analysis

open access: yesEngineering Reports, Volume 7, Issue 9, September 2025.
In this study, a new plan for routing radio transmitters is presented using an algorithm compatible with RFEH. The proposed algorithm is based on the genetic algorithm (GA), and in an innovation, using the HPBW in the GA creates a population for initial sampling dependent on the receiver antenna.

Early detection and location of unexpected events in buried pipelines under unseen conditions using the two‐stream global fusion classifier model

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 21, Page 3295-3315, 29 August 2025.
Abstract Failure of buried pipelines can result in serious impacts, such as explosions, environmental contamination, and economic losses. Early detection and location of unexpected events is crucial to prevent such events. However, conventional monitoring methods exhibit limited generalization performance under varying environmental and operational ...

Time Difference of Arrival (TDoA) Localization Combining Weighted Least Squares and Firefly Algorithm

open access: yesItalian National Conference on Sensors, 2019
Time difference of arrival (TDoA) based on a group of sensor nodes with known locations has been widely used to locate targets. Two-step weighted least squares (TSWLS), constrained weighted least squares (CWLS), and Newton–Raphson (NR) iteration are ...

Leveraging Whole Genomes, Mitochondrial DNA and Haploblocks to Decipher Complex Demographic Histories: An Example From a Broadly Admixed Arctic Fish

open access: yesMolecular Ecology, Volume 34, Issue 10, May 2025.
ABSTRACT The study of phylogeography has transitioned from mitochondrial haplotypes to genome‐wide analyses, borrowing from population genomics methods along the way. Whole‐genome sequencing allows the study of both mitochondrial and nuclear DNA and provides the density of markers to investigate recombination along the genome.
