Observation of *

open access: yesChinese Physics C, 2023
Abstract Using data taken at 29 center-of-mass energies between 4.16 and 4.70 GeV with the BESIII detector at the Beijing Electron Positron Collider corresponding to a total integrated luminosity of approximately 18.8 , the process

Practical challenges in data‐driven interpolation: Dealing with noise, enforcing stability, and computing realizations

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView., 2023
Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

Structural, dynamical and symbolic observability: From dynamical systems to networks. [PDF]

open access: yesPLoS ONE, 2018
Classical definitions of observability classify a system as either being observable or not. Observability has been recognized as an important feature to study complex networks, and as for dynamical systems the focus has been on determining conditions for

State Observability through Prior Knowledge: Analysis of the Height Map Prior for Track Cycling

open access: yesSensors, 2020
Inertial navigation systems suffer from unbounded errors in the position and orientation estimates. This drift can be corrected by applying prior knowledge, instead of using exteroceptive sensors. We want to show that the use of prior knowledge can yield

Adaptive transfer alignment method based on the observability analysis for airborne pod strapdown inertial navigation system

open access: yesScientific Reports, 2022
For the airborne pod strapdown inertial navigation system, it is necessary to use the host aircraft's inertial navigation system for the transfer alignment as quickly and accurately as possible in the flight process of the aircraft.

Observability Analysis of Sensor Bias Based on the Track-independent Model

open access: yesLeida xuebao, 2013
In this paper, an observability analysis of sensor bias based on the track-independent estimation model is presented. Observability analysis is a prerequisite for developing a systematic error estimation model.

Angle-Only Cooperative Orbit Determination Considering Attitude Uncertainty

open access: yesSensors, 2023
In this paper, a novel concept for cooperative orbit determination (OD) using inter-spacecraft angle-only measurements is proposed. Different from the conventional cooperative OD that only estimates orbit states, the attitude of the observer spacecraft ...

THE OBSERVER OBSERVED

open access: yesEpistemé: Jurnal Pengembangan Ilmu Keislaman, 2021
In his seminal Islam Observed: Religious Developments in Morocco and Indonesia from 1968, the American anthropologist Clifford Geertz (1926-2006) placed the comparative study of Muslim societies on the research agenda. In view of my knowledge on the history of Islam in Indonesia, it stroke me that the political dimension of religion did not take an ...

Observations on BPS observables in 6D [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2021
Abstract We study possible geometries and R-symmetry breaking patterns that lead to globally BPS surface operators in the six dimensional N = (
