Fixed points of \(p\)-hybrid \(L\)-fuzzy contractions
Sahand Communications in Mathematical Analysis, 2021 Summary: In this paper, the notion of \(p\)-hybrid \(L\)-fuzzy contractions in the framework of \(b\)-metric space is introduced. Sufficient conditions for existence of common \(L\)-fuzzy fixed points under such contractions are also investigated. The established ideas are generalizations of many concepts in fuzzy mathematics.

Validating predictions from climate envelope models. [PDF]
PLoS ONE, 2013 Climate envelope models are a potentially important conservation tool, but their ability to accurately forecast species' distributional shifts using independent survey data has not been fully evaluated.

Hybrid Multivalued Type Contraction Mappings in αK-Complete Partial b-Metric Spaces and Applications
Symmetry, 2019 In this paper, we initiate the notion of generalized multivalued ( α K * , Υ , Λ ) -contractions and provide some new common fixed point results in the class of α K -complete partial b-metric spaces.

A Family of Iterative Gauss-Newton Shooting Methods for Nonlinear Optimal Control
, 2017 This paper introduces a family of iterative algorithms for unconstrained nonlinear optimal control. We generalize the well-known iLQR algorithm to different multiple-shooting variants, combining advantages like straight-forward initialization and a ...

Advanced Biomedical Engineering, 2019 To evaluate muscle function accurately, it is necessary to simultaneously measure electromyogram (EMG) and mechanomyogram (MMG). We have developed an MMG/EMG hybrid transducer system that can simultaneously measure displacement-MMG (dMMG) and EMG, and ...

Transverse contraction criteria for stability of nonlinear hybrid limit cycles [PDF]
IEEE Conference on Decision and Control, 2014 In this paper, we derive differential conditions guaranteeing the orbital stability of nonlinear hybrid limit cycles. These conditions are represented as a series of pointwise linear matrix inequalities (LMI), enabling the search for stability ...

Fixed points of nonlinear contractions with applications
AIMS Mathematics, 2021 The aim of this paper is to initiate a new concept of nonlinear contraction under the name r-hybrid ψ-contraction and establish some fixed point results for such mappings in the setting of complete metric spaces.
