Oil Price Shocks and Stock Markets in Oil Importing Countries: Evidence from Egypt, Morocco, and Jordan

open access: yesScientific Annals of Economics and Business, 2021
This study aims to investigate the dynamic relationship between Oil price Shocks and stock markets returns in Egypt, Morocco, and Jordan as oil-importing countries in the MENA region, over the period (2005-2018). Vector auto regressive regressions (VAR),

An impulse response function for the “long tail” of excess atmospheric CO2 in an Earth system model

open access: yes, 2016
The ultimate fate of (fossil fuel) CO2 emitted to the atmosphere is governed by a range of sedimentological and geological processes operating on timescales of up to the ca. hundred thousand year response of the silicate weathering feedback. However, how

Reduced Complexity Approximation and Design of Gaussian Impulse Response Filters and Wavelets

open access: yesIEEE Access
A systematic method for realizing filters with a Gaussian impulse response is introduced in this work. For this purpose, the Laplace transform is used to obtain the transfer function which corresponds to the Gaussian impulse response. Since this transfer

Identification of Excitation Parameters Based on TLS - ESPRIT

open access: yesMATEC Web of Conferences, 2018
In order to accurately detect excitation system parameters, this paper presents a algorithm based on the TLS-ESPRIT. The matrix pencil algorithm is used to extract the frequency and damping of each component of system response. So it’s necessary to apply

Statistical Estimation and Hypothesis Testing on Impulse Response Function

open access: yesAustrian Journal of Statistics
In this paper a time-invariant continuous linear system is considered with a real-valued impulse response function (IRF) which is defined on a bounded domain. A sample input- output cross-correlogram is taken as an estimator of the response function.

Analysis of sensor impulse response effects on Cramèr–Rao lower bounds for signal parameter estimators

open access: yesThe Journal of Engineering, 2014
In this study, a generic analysis of sensor impulse response effects on linearly filtered channel noise is presented to illustrate the resulting variations to the Cramèr–Rao lower bounds (CRLBs) of signal parameter estimators in signal processing and ...

A Note on BIBO Stability

open access: yes, 2020
The statements on the BIBO stability of continuous-time convolution systems found in engineering textbooks are often either too vague (because of lack of hypotheses) or mathematically incorrect.

Rapid Response to Trametinib Combined With Chemotherapy for Infant BRAF‐Fused Chiasmatic Glioma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Infants, less than 1 year, with chiasmatic gliomas (ICG) present a major therapeutic challenge due to large tumor size, decreased vision, rapid progression, and poor response to vincristine/carboplatin chemotherapy. The majority have a BRAF fusion, which may respond to downstream MEK inhibitors but response time is slow. There are no safety or

Study on modeling of human postural control on frontal-plane during standing (Identication of a transfer function model by frequency response test)

open access: yesNihon Kikai Gakkai ronbunshu, 2015
We have been developing a standing ride type vehicle, such as electric skateboards. A human dynamics model is required to assist balance control of human standing in the vehicle.

A Criterion for Testing Hypothesis about Impulse Response Function

open access: yes, 2016
In this paper a time-invariant  continuous linear system  with a real-valued impulse response function is considered.  A new method for the estimator construction  of the impulse response function is proposed.
