Energy and waste data for the Algiers's EH-OS local system
No full textThis data is the primary data used for the system analysis. It was obtained from an investigation on the used fossil energy and the produced urban solid waste at the studied system. The survey aimed to estimate, on the one hand, the CO2 quantity resulting from fossil energy use and, on the other hand, the available deposits of waste that can be recovered as secondary resources. The survey on energy was carried out using the data obtained from the Algiers Electricity and Gas Distribution Company for the year 2016, and the Sonelgaz report on the national energy balance. Its elements relate to the final consumption of fossil fuel (gas and electricity) from the various urban sub-systems. The survey on urban solid waste was performed according to the data obtained from the National Waste Agency for 2016. Its elements relate to urban waste' categories, quantities, and components that can be valued as renewable energy or secondary material
Regularity estimates for fractional orthotropic p-Laplacians of mixed order
No full textChaker J, Ki M. Regularity estimates for fractional orthotropic p-Laplacians of mixed order. Advances in Nonlinear Analysis . 2022;11(1):1307-1331.We study robust regularity estimates for a class of nonlinear integro-differential operators with anisotropic and singular kernels. In this paper, we prove a Sobolev-type inequality, a weak Harnack inequality, and a local Holder estimate
Harnack inequality for nonlocal problems with non-standard growth
No full textChaker J, Ki M, Weidner M. Harnack inequality for nonlocal problems with non-standard growth. Mathematische Annalen . 2022;386:533–550 .We prove a full Harnack inequality for local minimizers, as well as weak solutions to nonlocal problems with non-standard growth. The main auxiliary results are local boundedness and a weak Harnack inequality for functions in a corresponding De Giorgi class. This paper builds upon a recent work on regularity estimates for such nonlocal problems by the same authors

-Laplacian of mixed order
No full textChaker J, Ki M, Weidner M. The concentration-compactness principle for the nonlocal anisotropic p-Laplacian of mixed order. Nonlinear Analysis : Theory, Methods & Applications . 2023;232: 113254.In this paper, we study the existence of minimizers of the Sobolev quotient for a class of nonlocal operators with an orthotropic structure having different exponents of integrability and different orders of differentiability. Our method is based on the concentration-compactness principle which we extend to this class of operators. One consequence of our main result is the existence of a nontrivial nonnegative solution to the corresponding critical problem.& COPY; 2023 Elsevier Ltd. All rights reserved

Invited Article: ultra-broadband terahertz coherent detection via a silicon nitride-based deep sub-wavelength metallic slit
No full textWe present a novel class of CMOS-compatible devices aimed to perform the solid-state-biased coherent detection of ultrashort terahertz pulses, i.e., featuring a gap-free bandwidth at least two decades-wide. Such a structure relies on a 1-mu m-wide slit aperture located between two parallel aluminum pads, embedded in a 1-mu m-thick layer of silicon nitride, and deposited on a quartz substrate. We show that this device can detect ultra-broadband terahertz pulses by employing unprecedented low optical probe energies of only a few tens of nanojoules. This is due to the more than one order of magnitude higher nonlinear coefficient of silicon nitride with respect to silica, the nonlinear material employed in the previous generations. In addition, due to the reduced distance between the aluminum pads, very high static electric fields can be generated within the slit by applying extremely low external bias voltages (in the order of few tens of volts), which strongly enhance the dynamic range of the detected THz waveforms. These results pave the way to the integration of solid-state ultra-broadband detection in compact and miniaturized terahertz systems fed by high repetition-rate laser oscillators and low-noise, low-voltage generators
