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

A different view on controllability and observability of continuous time linear systems with interval coefficients [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2020
We discuss the controllability and observability of time-invariant (continuous time) linear systems with interval coefficients using the notion of being full rank of interval matrices.

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.

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

On statistical power grid observability under communication constraints (invited paper)

open access: yesIET Smart Grid, 2018
Phasor Measurement Units (PMUs) have enabled real-time power grid monitoring and control applications realizing an integrated power grid and communication system. The communication network formed by PMUs has strict latency requirements.

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.

Close Loop Design in Glucose Insulin Model with Effect of ‎Physical Exercise [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2021
The minimal mathematical models for exercise and its extension is included the major exercise effects on plasma glucose and insulin levels. Model expectations for glucose and insulin dynamics are steady with current literature statistics.

Observations on the observer pattern [PDF]

open access: yesProceedings of the 17th Conference on Pattern Languages of Programs, 2010
A group of students who should have been familiar with basic design principles and MVC all failed to implement the Observer design pattern correctly while at the same time violating several design principles. This paper discusses what went wrong and why it probably went wrong.
