An assessment of the performance of a 1.5 μm Doppler lidar for operational vertical wind profiling based on a 1-year trial [PDF]

open access: yesAtmospheric Measurement Techniques, 2015
We present the results of a 1-year quasi-operational testing of the 1.5 μm StreamLine Doppler lidar developed by Halo Photonics from 2 October 2012 to 2 October 2013.

Error propagation in polarimetric demodulation [PDF]

open access: yes, 2008
The polarization analysis of the light is typically carried out using modulation schemes. The light of unknown polarization state is passed through a set of known modulation optics and a detector is used to measure the total intensity passing the system.

Inference in the indeterminate parameters problem

open access: yesStatistica, 2013
We face an indeterminate parameters problem when there are two sets of parameters, x and g, say, such that the null hypothesis H0:x=x0 makes the likelihood independent of g. A consequence of indeterminacy is the singularity of the information matrix. For

Protocols for entanglement transformations of bipartite pure states [PDF]

open access: yes, 2002
We present a general theoretical framework for both deterministic and probabilistic entanglement transformations of bipartite pure states achieved via local operations and classical communication.

On the Relative Gain Array (RGA) with Singular and Rectangular Matrices

open access: yes, 2019
In this paper we identify a significant deficiency in the literature on the application of the Relative Gain Array (RGA) formalism in the case of singular matrices.

A new hybrid method for size and topology optimization of truss structures using modified ALGA and QPGA

open access: yesJournal of Civil Engineering and Management, 2017
Modified Augmented Lagrangian Genetic Algorithm (ALGA) and Quadratic Penalty Function Genetic Algo­rithm (QPGA) optimization methods are proposed to obtain truss structures with minimum structural weight using both continuous and discrete design ...

From Origami to Bistable and Laminate Structures: A Review for Multifunctional Applications from Structural Perspective of Shape‐Changing Structures

open access: yesAdvanced Intelligent Systems, EarlyView.
This review explores how shape‐changing structures—origami, bistable, and laminate structures—enable multifunctionality in soft robotics and metamaterials. Starting from structural design, it examines core principles, real‐world applications, and ongoing challenges.

Solvability of Caputo fractional integral boundary value problem at resonance in R n ${\mathbb{R}^{n}}$

open access: yesJournal of Inequalities and Applications
In this paper, we utilize the continuation theorem due to Mawhin to investigate the solvability for a class of Caputo fractional system integral boundary value problems at resonance.

Boundary-Value Problems for Weakly Nonlinear Delay Differential Systems

open access: yesAbstract and Applied Analysis, 2011
Conditions are derived of the existence of solutions of nonlinear boundary-value problems for systems of n ordinary differential equations with constant coefficients and single delay (in the linear part) and with a finite number of measurable delays of ...
