Interleavers [PDF]

open access: yes, 2006
The chapter describes principles, analysis, design, properties, and implementations of optical frequency (or wavelength) interleavers. The emphasis is on finite impulse response devices based on cascaded Mach-Zehnder-type filter elements with carefully ...

Methodology for Verifying the Indication Correctness of a Vessel Compass Based on the Spectral Analysis of Heading Errors and Reliability Theory

open access: yesSensors, 2022
This article presents a novel method for validating compass devices. To this end, the post-processing method was used, i.e., the previously recorded vessel’s heading from three compass devices was applied.

Critical earthquake response of elastic-plastic structures under near-fault ground motions (Part 1: Fling-step input)

open access: yesFrontiers in Built Environment, 2015
The double impulse input is introduced as a substitute of the fling-step near-fault ground motion and a closed-form solution of the elastic-plastic response of a structure by the ‘critical double impulse input’ is derived.

Exploring river–aquifer interactions and hydrological system response using baseflow separation, impulse response modeling, and time series analysis in three temperate lowland catchments [PDF]

open access: yesHydrology and Earth System Sciences, 2022
Lowland rivers and shallow aquifers are closely coupled, and their interactions are crucial for maintaining healthy stream ecological functions. To explore river–aquifer interactions and the lowland hydrological system in three Belgian catchments, we ...

Evaluation of Lightning Impulse Test by Frequency Response Analysis [PDF]

open access: yes, 2006
In this work are presented the basis for improving the interpretation of transformer lightning impulse test and the development of a graphical user interface system, which allows comparisons of time domain data and frequency response.

Critical Response of Single-Degree-of-Freedom Damped Bilinear Hysteretic System under Double Impulse As Substitute for Near-Fault Ground Motion

open access: yesFrontiers in Built Environment, 2018
A double impulse input is used as a substitute for near-fault earthquake ground motions. An explicit expression is derived on the maximum elastic–plastic response of a single-degree-of-freedom damped structure with bilinear hysteresis under the “critical

Crecimiento económico en América Latina y el rol de China. Un análisis desde el Neo-estructuralismo latinoamericano. [PDF]

open access: yesJanus.net, 2022
This research aims is to analyze the role that the Chinese economy has had in the economic growth of Latin America. The methodology used consists of a multivariate approach for time series, and causal relationships are obtained through the impulse ...

Modelling the Fiscal Effects of Aid: An Impulse Response Analysis for Ghana [PDF]

open access: yesSSRN Electronic Journal, 2003
An important feature of aid to developing countries is that it is given to the government. As a result, aid should be expected to affect fiscal behaviour. Traditional approaches to modelling fiscal effects are beset by theoretical and empirical problems.

High-resolution modal analysis [PDF]

open access: yes, 2008
Usual modal analysis techniques are based on the Fourier transform. Due to the Delta T . Delta f limitation, they perform poorly when the modal overlap mu exceeds 30%.

Critical earthquake response of elastic-plastic structures under near-fault ground motions (Part 2: Forward-directivity input)

open access: yesFrontiers in Built Environment, 2015
The triple impulse input is used as a simplified version of the forward-directivity near-fault ground motion and a closed-form solution of the elastic-plastic response of a structure by this triple input is obtained.
