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 …

Innovative Wireless Localization Techniques and Applications
Innovative methodologies for the wireless localization of users and related applications are addressed in this thesis. In last years, the widespread diffusion of pervasive wireless communication (e.g., Wi-Fi) and global localization services (e.g., GPS) has boosted the interest and the research on …

Percussion Based Detection Method for Localization of Pipe Inspection Gauge using Advanced Machine Learning Classification and Clustering Techniques.
… extremely costly and time consuming. Various PIG localization techniques have been invented, using a whole suite of advanced instruments, from global positioning to magnetic based tracking to percussion based. Percussion based detection in particular stands out due to its ability to be done in all …

Peer-to-peer wireless ultrawide-band localization of fast-moving entities
This thesis presents peer-to-peer localization techniques such that a group of mobile nodes can continuously track its topology, without relying on external infrastructure. Ultrawide-band (UWB) radios worn by each node (humans in our case) perform time-of-flight (TOF) measurements between different …
