An improved approach by introducing copula functions for structural reliability analysis under hybrid uncertainties

open access: yesAdvances in Mechanical Engineering, 2018
The structural composition of the oil platform is very complicated, and its working environment is harsh, thus conducting a large number of reliability tests is not feasible, and the field tests are also hard to accomplish.

Imprecise Synthesis

open access: yes, 2004
Around a third of significant faults in embedded systems are caused by defective requirements specifications. Industrial case studies using existing techniques to construct analytical requirements models have been frustrated because of imprecise ...

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

open access: yesThe Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Data Imprecision in Computational Geometry.

open access: yes, 2009
The field of computational geometry is concerned with the design and analysis of geometric algorithms. For such algorithms, correctness and efficiency proofs are constructed, or problems are proven to be hard when no correct and efficient algorithms exist. In order to be able to do this, several assumptions about the input data for geometric algorithms

Model parameter estimation with imprecise information

open access: yesWater Science and Technology
Model parameter estimation is a well-known inverse problem, as long as single-value point data are available as observations of system performance measurement.

A fuzzy multiple objective programming to dea with imprecise data 

open access: yes, 2020
[[abstract]]A fuzzy multiple objective programming approach to data envelopment analysis (DEA) of imprecise data is proposed in this paper. The problems involving a mixture of imprecise and exact data for all decision making units (DMUs) could be ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Neutrostat: An R package for neutrosophic statistical models

open access: yesSoftwareX
In many practical applications, we consider indeterminate and ambiguous information in data. Traditional statistical methods address data formed by precise knowledge, whereas neutrosophic statistical (NS) approaches analyze data that result from ...

Imprecise Regression and Regression on Fuzzy Data - A Preliminary Discussion

open access: yes, 2006
SerrP005International audienceThe paper provides a discussion of the possibilistic regression method originally proposed by H. Tanaka. This method has the advantage of allowing the learning of an imprecise model, in the form of an interval-valued ...

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

open access: yesThe Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...
