DE L’IMPACT DE LA LIBÉRALISATION DU SECTEUR D’ASSURANCES EN RÉPUBLIQUE DÉMOCRATIQUE DU CONGO : « CAS DE L’INDEMNISATION DES ASSURÉS EN ARCA » [PDF]

Cahiers Africains des Droits de l’Homme et de la Démocratie ainsi que du Développement Durable
L'assurance résulte d'un mécanisme financier induit par les exigences de protection des patrimoines contre les risques. Elle est donc liée au développement du commerce et aux transformations sociales. Au contraire du Banquier, l'assureur de dommages ne s'

Simple Design Procedure of a Broadband Circularly Polarized Slot Monopole Antenna Assisted by Characteristic Mode Analysis

IEEE Access, 2018
In this paper, a systematic design procedure of a compact and broadband circularly polarized (CP) antenna is proposed. The antenna is first designed with a C-shaped monopole, and then a C-shaped slotted patch is utilized to produce CP radiation in the ...

f(R) global monopole revisited [PDF]

, 2017
In this paper the f(R) global monopole is reexamined. We provide an exact solution for the modified field equations in the presence of a global monopole for regions outside its core, generalizing previous results. Additionally, we discuss some particular

Second Chern number of a quantum-simulated non-Abelian Yang monopole [PDF]

Science, 2016
Going beyond the first Chern number Topological properties of physical systems are reflected in so-called Chern numbers: A nonzero Chern number typically means that a system is topologically nontrivial. Sugawa et al.

Thermal monopoles

Journal of High Energy Physics, 2000
Evidence is given that some particles with large charges in gauge theories, including 4d N=4 SU(3) and 5d theories with N=1 supersymmetry, have macroscopic entropy. The ground state entropy is found to be extensive in the charges. The mass gap for excitation is estimated and is of the same order as the binding energy.

Isoscalar monopole excitations in $^{16}$O: $\alpha$-cluster states at low energy and mean-field-type states at higher energy

, 2011
Isoscalar monopole strength function in $^{16}$O up to $E_{x}\simeq40$ MeV is discussed. We found that the fine structures at the low energy region up to $E_{x} \simeq 16$ MeV in the experimental monopole strength function obtained by the $^{16}$O ...

Acoustic Pressure Monopole, Velocity Monopole, and Hybrid Monopole

, 2018
We show that there are two types of acoustic monopoles, namely the pressure monopoles (PMs) and the velocity monopoles (VMs). Under one wave incidence, only the pressure field near a PM at resonance possesses monopolar symmetry, while for a VM at resonance only the velocity field possesses monopolar symmetry.

Nonlocal active sound control for composite regions

Mathematical Methods in the Applied Sciences, EarlyView.
In the active sound control problem, additional sound sources, known as control sources, are implemented at the perimeter of a protected domain. The control sources can generate secondary sound inside the shielded domain, which attenuates incoming noise. This leads to an inverse source problem.
