Interval Analysis and Robotics [PDF]

open access: yes, 2006
Robotics is a field in which numerous linear and non linear problems are occuring. The unknowns of these problems have a physical meaning and roboticians are usually interested only in solutions within restricted bounds. Furthermore dealing with uncertainties is unavoidable as any robot is a controlled mechanical system with manufacturing and control ...

Multi-level Interval Rolling Warning Method for Distributed Photovoltaic Fluctuation Events

open access: yesZhongguo dianli
Under the influence of large-area extreme weather conditions, the impact of distributed photovoltaic fluctuations on power system balance is significant and may lead to risks such as curtailment of solar power and load shedding.

A Novel Joint TDOA/FDOA Passive Localization Scheme Using Interval Intersection Algorithm

open access: yesInformation, 2021
Due to the large measurement error in the practical non-cooperative scene, the passive localization algorithms based on traditional numerical calculation using time difference of arrival (TDOA) and frequency difference of arrival (FDOA) often have no ...

Power Pattern Sensitivity to Calibration Errors and Mutual Coupling in Linear Arrays through Circular Interval Arithmetics

open access: yesSensors, 2016
The sensitivity to both calibration errors and mutual coupling effects of the power pattern radiated by a linear array is addressed. Starting from the knowledge of the nominal excitations of the array elements and the maximum uncertainty on their ...

Methodology for the Assessment of Imprecise Multi-State System Availability

open access: yesMathematics, 2022
Most existing studies of a system’s availability in the presence of epistemic uncertainties assume that the system is binary. In this paper, a new methodology for the estimation of the availability of multi-state systems is developed, taking into ...

Health‐Related Social Needs in Children With Sickle Cell Disease Are Associated With Worse Health‐Related Quality of Life

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...

The Combined Effect of Obesity and Contraceptive Use on Pulmonary Embolism in Adolescent Females Residing in the United States

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Combined oral contraceptive (COC) use in obese adult women dramatically increases the relative risk of developing a pulmonary embolism (PE). The risk of a PE in obese adolescent females taking contraceptives is currently unknown. The purpose of this investigation was to determine the effect of body mass index (BMI) and contraceptive

Interregional Production Balance Modeling Using Interval and Entropy Approaches [PDF]

open access: yesПространственная экономика, 2009
The paper considers an interval model of interregional trade interaction potential, based on the combination of the input-output balance approach, the entropy equilibrium principle and the conception of universal solutions of interval optimization ...

Meta-analysis: Confidence intervals and Prediction intervals

open access: yesAnales de Psicología
Several types of intervals are usually employed in meta-analysis, a fact that has generated some confusion when interpreting them. Confidence intervals reflect the uncertainty related to a single number, the parametric mean effect size. Prediction intervals reflect the probable parametric effect size in any study of the same class as those included in ...
