Pairs of fixed points for a class of operators on Hilbert spaces
A. Mokhtari, K. Saoudi, D. D. Repovš
In this paper, existence of pairs of solutions is obtained for compact potential operators on Hilbert spaces. An application to a second-order boundary value problem is also given…
EUSO-SPB1 Mission and Science
EUSO Collaboration, G. Abdellaoui, S. Abe +292
The Extreme Universe Space Observatory on a Super Pressure Balloon 1 (EUSO-SPB1) was launched in 2017 April from Wanaka, New Zealand. The plan of this mission of opportunity on a N…
Boundary stabilization of a vibrating string with variable length
Seyf Eddine Ghenimi, Abdelmouhcene Sengouga
We study small vibrations of a string with time-dependent length and boundary damping. The vibrations are described by a 1-d wave equation in an interval with one moving…
Energy decay estimates for an axially travelling string damped at one end
Seyf Eddine Ghenimi, Abdelmouhcene Sengouga
We study the small vibrations of an axially travelling string with a dashpoint damping at one end. The string is modelled by a wave equation in a time-dependent interval with two e…
Free vibrations of axially moving strings: Energy estimates and boundary observability
Seyf Eddine Ghenimi, Abdelmouhcene Sengouga
We study the small vibrations of axially moving strings described by a wave equation in an interval with two endpoints moving in the same direction with a constant speed. The solut…
Simulations studies for the Mini-EUSO detector
H. Miyamoto, F. Fenu, D. Barghini +31
Mini-EUSO is a mission of the JEM-EUSO program flying onboard the International Space Station since August 2019. Since the first data acquisition in October 2019, more than 35 sess…
Study of the calibration method using the stars measured by the EUSO-TA telescope
Z. Plebaniak, M. Przybylak, D. Barghini +8
EUSO-TA is a ground-based experiment, placed at Black Rock Mesa of the Telescope Array site as a part of the JEM-EUSO (Joint Experiment Missions for the Extreme Universe Space Obse…
Testing The Lamp-Post and Wind Reverberation Models with XMM-Newton Observations of NGC 5506
Abderahmen Zoghbi, Sihem Kalli, Jon M Miller +1
The lamp-post geometry is often used to model X-ray data of accreting black holes. Despite its simple assumptions, it has proven to be powerful in inferring fundamental black hole…
Continuous characterization of Besov spaces of variable smoothness and integrability
Douadi Drihem, Salah Ben Mahmoud
In this paper the authors obtain a new equivalent norms of the Besov spaces of variable smoothness and integrability. Our main tools are the continuous version of Calderon reproduc…
First observations of speed of light tracks by a fluorescence detector looking down on the atmosphere
G. Abdellaoui, S. Abe, J. H. Adams +311
EUSO-Balloon is a pathfinder mission for the Extreme Universe Space Observatory onboard the Japanese Experiment Module (JEM-EUSO). It was launched on the moonless night of the 25$^…
Caffarelli-Kohn-Nirenberg inequalities on Besov and Triebel-Lizorkin-type spaces
Douadi Drihem
We present some Caffarelli-Kohn-Nirenberg-type inequalities on Herz-type Besov-Triebel-Lizorkin spaces, Besov-Morrey spaces and Triebel-Lizorkin-Morrey spaces. More Precisely, we i…
Real interpolation with variable exponent
Douadi Drihem
We present the real interpolation with variable exponent and we prove the basic properties in analogy to the classical real interpolation. More precisely, we prove that under some…
Observability and controllability of the 1--d wave equation in domains with moving boundary
Abdelmouhcene Sengouga
By mean of generalized Fourier series and Parseval's equality in weighted --spaces, we derive a sharp energy estimate for the wave equation in a bounded interval with a movi…
Debugging of Markov Decision Processes (MDPs) Models
Hichem Debbi
In model checking, a counterexample is considered as a valuable tool for debugging. In Probabilistic Model Checking (PMC), counterexample generation has a quantitative aspect. The…
Transverse momentum correlations of quarks in recursive jet models
X. Artru, Z. Belghobsi, E. Redouane-Salah
In the symmetric string fragmentation recipe adopted by PYTHIA for jet simulations, the transverse momenta of successive quarks are uncorrelated. This is a simplification but has n…
Diophantine approximation with improvement of the simultaneous control of the error and of the denominator
Abdelmadjid Boudaoud
In this work we proof the following theorem which is, in addition to someother lemmas, our main result:\noindent \textbf{theorem}. Let$\ X=\{ ( x\_{1}\text{, }%t\_{1}) \text{, }( x…
On the composition ideals of Lipschitz mappings
Khalil Saadi
We study in this paper some property of Lipschitz mappings which admit factorization through an operator ideal. We try to construct Lipschitz cross-norms from known tensor norms in…
Sobolev embeddings for Herz-type Triebel-Lizorkin spaces
Douadi Drihem
In this paper we prove the Sobolev embeddings for Herz-type Triebel-Lizorkin spaces, \begin{equation*} \dot{K}_{q}^{α_{2},r}F_{θ}^{s_{2}}\hookrightarrow \dot{K}%_{s}^{α_{1},p}F_{β}…
Transverse momentum asymmetry of the extracted electron in field ionization of a Hydrogen Atom with angular momentum
Xavier Artru, Essma Redouane-Salah
The tunneling ionization of a hydrogen atom excited in the presence of a static electric field is investigated for the case where, before being extracted, the electron has an orbit…
Distortion of the ultrahigh energy cosmic ray flux from rare transient sources in inhomogeneous extragalactic magnetic fields
Sihem Kalli, Martin Lemoine, Kumiko Kotera
Detecting and characterizing the anisotropy pattern of the arrival directions of the highest energy cosmic rays are crucial steps towards the identification of their sources. We di…
