A field surveying on the geodetic control of engineering linear structures using a terrestrial laser scanner

open access: yesGeodesy and Cartography, 2019
The method of geodetic control of the road pavement using TLS is presented. The use of the terrestrial laser scanner can avoid some of the disadvantages of classical methods for determining the deformation of objects.

Three-Bar structure optimality criterion using the linear resizing rule

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2021
The static analysis of the indeterminate three-bar structure is developed using the Castigliano's first theorem, taking the lengths and inclination angles as variables. Some reductions are applied in the resulting set of equations to approximate them to

Cone type majorization and its strong linear preservers [PDF]

open access: yes, 2020
This study introduces a novel notion, cone type majorization and characterizes the same. Further, the structure of linear preservers and strong linear preservers of this cone type majorization have been ...

Validating linear restrictions in linear regression models with general error structure [PDF]

open access: yes, 2006
A new method for testing linear restrictions in linear regression models is suggested. It allows to validate the linear restriction, up to a specified approximation error and with a specified error probability.

Interval state estimator for linear systems with known structure

open access: yesМіжнародний науково-технічний журнал "Проблеми керування та інформатики", 2023
It is often required to control a system whose state is not observable directly. Instead, there are indirect incomplete and noised measurements of its state.

Linear preservers and quantum information science [PDF]

open access: yes, 2013
In this article, a brief survey of recent results on linear preserver problems and quantum information science is given. In addition, characterization is obtained for linear operators φ on mn × mn Hermitian matrices such that φ(A ⊗ B) and A ⊗ B have the ...

Clockwork/linear dilaton: structure and phenomenology

open access: yesJournal of High Energy Physics, 2018
The linear dilaton geometry in five dimensions, rediscovered recently in the continuum limit of the clockwork model, may offer a solution to the hierarchy problem which is qualitatively different from other extra-dimensional scenarios and leads to ...

Applying Bayes linear methods to support reliability procurement decisions [PDF]

open access: yes, 2008
Bayesian methods are common in reliability and risk assessment, however, such methods often demand a large amount of specification and can be computationally intensive.

Asymptotic Normality in Linear Regression with Approximately Sparse Structure

open access: yesMathematics, 2022
In this paper, we study the asymptotic normality in high-dimensional linear regression. We focus on the case where the covariance matrix of the regression variables has a KMS structure, in asymptotic settings where the number of predictors, p, is ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
