Structural Concrete, EarlyView.Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Simplified analysis of concentrically loaded reinforced concrete columns
Structural Concrete, EarlyView.Abstract Reinforced concrete columns subjected to concentric and eccentric compression loads are typically treated in an identical manner, taking into account both the imperfect shape, creep, and the second order effects, as described for example in fib Model Code 2020 and Eurocode 2.

Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites
Wildlife Biology, EarlyView.Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.

New Quasi-Newton (Dfp) With Logistic Mapping
Science Journal of University of Zakho, 2016 In this paper, we propose a modification of the self-scaling quasi-Newton (DFP) method for unconstrained optimization using logistic mapping. We shoe that it produces a positive definite matrix.

Quasi-Newton Methods for Solving Nonlinear Programming Problems [PDF]
Computer Science Journal of Moldova, 1996 In the present paper the problem of constrained equality optimization is reduced to sequential solving a series of problems of quadratic programming. The Hessian of the Lagrangian is approximated by a sequence of symmetric positive definite matrices. The

Distributed k‐WTA Network for Multi‐Manipulator Competition With Experimental Verifications
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT In this article, a new distributed k $k$‐winner‐take‐all (Dk $k$‐WTA) network is designed and used to construct a dynamic allocation scheme for competitive coordination tasks of multiple manipulators as embodied agents. The scheme is constructed based on the following two aspects. On one hand, with reference to a perspective that the Laplacian

Extending Broyden's method to interaction problems
Journal of Numerical Analysis and Approximation Theory, 2008 The solution of problems involving the interaction of different systems is a domain of ongoing research, although often a good solver already exists for each system separately.

Energy Internet, EarlyView.ABSTRACT The combination of electric‐heating interconnected microgrids (EHIMs) with grid‐forming converters (GFMCs) offers a highly promising approach to improving energy management within decentralised energy systems. Despite its potential, precisely modelling and analysing energy flow in such systems remains a considerable challenge due to the ...

On the convergence of some quasi-Newton iterates studied by I. Păvăloiu
Journal of Numerical Analysis and Approximation Theory, 2015 In a paper from 1986, Păvăloiu \cite{Pavaloiu 1986} has considered the fixed point problem (in Banach space setting) \[ x=\lambda D\left( x\right) +y, \qquad \lambda\in {\mathbb R}, \] written in the form \(x -\lambda D\left( x\right) -y\) and solved ...
