Variable Stiffness Model Construction and Simulation Verification of Coupled Notch Continuum Manipulator

open access: yesIEEE Access, 2019
The continuum manipulators, which have gradually become a research hotspot of minimally invasive surgery have the characteristics of small size, lightweight, and better environmental adaptability.

Robust Localization Based on Mixed-Norm Minimization Criterion

open access: yesIEEE Access, 2022
This paper presents robust positioning methods that use range measurements to estimate location parameters. The existing maximum correntropy criterion-based localization algorithm uses only the $l_{2}$ norm minimization.

Two-Stage Code Acquisition Employing Search Space Reduction and Iterative Detection in the DS-UWB Downlink [PDF]

open access: yes, 2008
—In this paper we propose and investigate an iterative code acquisition scheme assisted by both search space reduction and iterative Massage Passing (MP), which was designed for the Direct Sequence-Ultra WideBand (DS-UWB) DownLink (DL).

A comparison of multi-carrier OFDM and single carrier iterative equalisation for future high performance wireless local area networks [PDF]

open access: yes, 2002
There has been a strong trend towards the specification of multi-carrier coded orthogonal frequency division multiplexing (COFDM) in the physical layer of emerging high performance wireless local area networks (WLAN).

Contributions to Elimination of Excitation Field Harmonics in Turbogenerators

open access: yesAdvances in Electrical and Computer Engineering, 2022
Turbogenerators driven by high-speed turbines are frequently used in electrical power generation. Power quality of a synchronous generator is directly associated with its excitation field harmonics.

State determination: An iterative algorithm [PDF]

open access: yesPhysical Review A, 2008
An iterative algorithm for state determination is presented that uses as physical input the probability distributions for the eigenvalues of two or more observables in an unknown state $Φ$. Starting form an arbitrary state $Ψ_{0}$, a succession of states $Ψ_{n}$ is obtained that converges to $Φ$ or to a Pauli partner.

Normalised iterative hard thresholding: guaranteed stability and performance [PDF]

open access: yes, 2010
Sparse signal models are used in many signal processing applications. The task of estimating the sparsest coefficient vector in these models is a combinatorial problem and efficient, often suboptimal strategies have to be used. Fortunately, under certain

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
