Nonparametric frontier estimation from noisy data [PDF]

A new nonparametric estimator of production frontiers is defined and studied when the data set of production units is contaminated by measurement error. The measurement error is assumed to be an additive normal random variable on the input variable, but ...

An Increase in Estimation Accuracy Position Determination of Inertial Measurement Units

MATEC Web of Conferences, 2016
This paper deals with an increase in measurement accuracy of the Inertial Measurement Units (IMU). In the Inertial Navigation Systems (INS) a fusion of gyroscopes, accelerometers and in some cases magnetometers are typically used.

Direct high-precision measurement of the magnetic moment of the proton

, 2014
The spin-magnetic moment of the proton $\mu_p$ is a fundamental property of this particle. So far $\mu_p$ has only been measured indirectly, analysing the spectrum of an atomic hydrogen maser in a magnetic field. Here, we report the direct high-precision

Fault Location in Distribution Network Based on Phasor Measurement Units (PMU)

The Scientific Bulletin of Electrical Engineering Faculty, 2019
Nowadays, phasor measurement units have many applications in the power network. Fault location using the network’s impedance matrix and phasor measurement units (PMU) is a subject that has been recently brought to the location light. In this research, we
