Stability issues in German money multiplier forecasts [PDF]

This paper investigates the stability of the German money supply focusing on the period 1991 - 1998. It is shown that the standard ARIMA-Transfer model approach in the literature needs to be augmented by a cointegration term to adequately model the ...

A Kantorovich Version of Bernstein‐Type Logarithmic Operators

Mathematische Nachrichten, EarlyView.
ABSTRACT In this paper, we introduce a Kantorovich version of the Bernstein‐type logarithmic operators. The idea comes from the wide literature concerning exponential polynomials that preserve exponential functions: here, the exponential weights are replaced by logarithmic ones and the corresponding operators preserve the logarithmic functions.

FOREIGN TRADE MULTIPLIER IN ROMANIA BEFORE AND AFTER ACCESSION TO THE EUROPEAN UNION [PDF]

In this paper we compute the foreign trade multiplier on Romanian exports and imports data during 1990-2008. Our motivation comes from the need to determine the trade performance and trade efficiency using proper indicators The multiplier of foreign ...

A Multiplier Theorem on Anisotropic Hardy Spaces

, 2018
We present a multiplier theorem on anisotropic Hardy spaces. When m satisfies the anisotropic, pointwise Mihlin condition, we obtain boundedness of the multiplier operator Tm: → , for the range of p that depends on the eccentricities of the dilation A ...

An Implicit Nodal–Staggered Finite Difference Scheme for Damped Shear Beam Models Without Rotational Inertia

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop and analyze a fully discrete finite difference approximation for a damped shear beam model with mixed boundary conditions and no rotational inertia. The absence of a second‐order time derivative in the rotational equation gives rise to an asymmetric temporal structure.

AI‐Based PV Fault Detection: Benchmarking Indicators and Feature Selection Methods

Progress in Photovoltaics: Research and Applications, EarlyView.
This article benchmarks indicators for automated defect detection in photovoltaic modules. The methodology has three phases: generating a simulated ideal defect‐free I‐V curve, comparing it with experimental measurements under standard test conditions, calculating indicators, and applying a feature‐selection strategy to identify the most relevant ...

Pointwise Multipliers of Orlicz-Morrey Spaces

Journal of the Indonesian Mathematical Society
We investigate the space of pointwise multipliers of Orlicz-Morrey spaces. Using the H\"older inequality in Orlicz-Morrey spaces, we prove that the space of pointwise multipliers of Orlicz-Morrey spaces contains an Orlicz-Morrey space. We also prove a partial reverse inclusion of this result.

Adaptive Sliding‐Mode Control of a Perturbed Diffusion Process With Pointwise In‐Domain Actuation

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT A sliding mode–based adaptive control law is proposed for a class of diffusion processes featuring a spatially‐varying uncertain diffusivity and equipped with several point‐wise actuators located at the two boundaries of the spatial domain as well as in its interior.

Experimental Investigation of Electrical Parameter Effects in Wire Arc Atomization of 316L Stainless Steel Powders for Additive Manufacturing

steel research international, EarlyView.
This article presents wire arc atomization of 316L for the production of metallic powders used in additive manufacturing, with a systematic analysis of the influence of arc parameters on particle size. Through the application of dry sieving, scanning electron microscopy, and shape analysis, it is demonstrated that this technique is well‐suited for ...

Ricardian equivalence and the intertemporal Keynesian multiplier [PDF]

We show that Keynesian multiplier effects can be obtained in dynamic optimizing models if one combines both price rigidities and a "non Ricardian" framework where, due for example to the birth of new agents, Ricardian equivalence does not hold.multiplier
