Bayesian In-Situ Calibration of Multiport Antennas for DoA Estimation: Theory and Measurements

IEEE Access, 2022
The DoA of radio waves is used for many applications, e.g. the localization of autonomous robots and smart vehicles. Estimating the DoA is possible with a multiport antenna, e.g. an antenna array or a multi-mode antenna (MMA). In practice, DoA estimation

A comparative analysis of auto-calibration strategies for the urban hydrologic model

Hydrology Research
Calibrating hydrologic models in the urban environment is a challenging task due to data uncertainty in drainage networks, flow observation, and topography, which, however, can be aided by auto-calibration methods to facilitate the optimization process ...

Error Estimation for the Linearized Auto-Localization Algorithm

Sensors, 2012
The Linearized Auto-Localization (LAL) algorithm estimates the position of beacon nodes in Local Positioning Systems (LPSs), using only the distance measurements to a mobile node whose position is also unknown.

Calibration bands for mean estimates within the exponential dispersion family

Statistical Theory and Related Fields
A statistical model is said to be calibrated if the resulting mean estimates perfectly match the true means of the underlying responses. Aiming for calibration is often not achievable in practice as one has to deal with finite samples of noisy ...

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

Molecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

Resolving ambiguities in auto–calibration

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1998
Summary: Three-dimensional (3D) projective structure, that is structure modulo a projectivity of 3D space, can be recovered from its projection in multiple perspective images. The images might be acquired, for example, by a moving monocular camera or a stereo rig.
