How to Measure Magnetic Flux with a Single Position Measurement? [PDF]
, 2015 Current methods for measuring magnetic flux are based on performing many measurements over a large ensemble of electrons. We propose a novel method based on wavefunction "revival" for measuring the flux modulo hc/2e using only a single electron.

Positive Martingales and Their Induced Measures [PDF]
Proceedings of the American Mathematical Society, 1983 Consider a probability space (\(\Omega\),\({\mathcal F},P)\), an increasing sequence \(\{ {\mathcal F}_ n| n\in {\mathbb{N}}\}\) of sub-\(\sigma\) -algebras of \({\mathcal F}\) such that \({\mathcal F}\) is generated by \(\cup {\mathcal F}_ n\), and a probability measure Q on \({\mathcal F}\).

Floor Sensing System Using Laser Reflectivity for Localizing Everyday Objects and Robot
Sensors, 2014 This paper describes a new method of measuring the position of everyday objects and a robot on the floor using distance and reflectance acquired by laser range finder (LRF). The information obtained by this method is important for a service robot working

Collaborative Geolocation Based on Imprecise Initial Coordinates for Internet of Things
IEEE Access, 2018 Non-linear minimum optimization methods, like maximum likelihood estimation method, have been heavily employed in range-based localization problems in plenty of research. However, conventional optimization methods require precise initial values. When the

Quantum Measurement, Gravitation, and Locality [PDF]
, 1994 This essay argues that when measurement processes involve energies of the order of the Planck scale, the fundamental assumption of locality may no longer be a good approximation.

Linear motor for multi-car elevators, design and position measurement [PDF]
, 2010 Multi-car elevator is an emerging technology consisting of two or more elevator cars moving independently in an elevator hoistway, which has become more appealing as building heights increase.

Labelled GM-CBMEMBER filter with adaptive track initiation
The Journal of Engineering, 2019 The initial Gaussian mixture cardinality balanced multi-target multi-Bernoulli (GM-CBMeMBer) filter does not provide track information and assumes that the target birth intensity is known as a priori, but in reality the target may appear anywhere in the ...
