Constraining Cosmological Parameters From Statistical Superluminal Effects Without a Distance Ladder
Hichem Guergouri, Omar Nemoul, Jamal Mimouni
We employ a statistical approach to study apparent superluminal motion of luminous sources in an expanding flat Friedmann--Lemaître--Robertson--Walker universe, explicitly incorpor…
Studying the Behavior of Radial Free Geodesics in ΛCDM Model
Omar Nemoul, Hichem Guergouri, Jamal Mimouni
This paper presents an analytical study of the behavior of radial free-geodesics in the Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime within the Lambda Cold Dark Matter (ΛCD…
Handling Trust in A Cloud Based Multi Agent System
Imen Bouabdallah, Hakima Mellah
Cloud computing is an opened and distributed network that guarantees access to a large amount of data and IT infrastructure at several levels (software, hardware...). With the incr…
A 331 Model for Lepton Flavor Universality Violation in Decays
Soumia Lebbal, Jamal Mimouni, Noureddine Mebarki
Lepton Flavor Universality Violation (LFUV) in decays in both neutral and charged processes observed in the ratios $R_{K^{(*…
A glint in the eye: photographic plate archive searches for non-terrestrial artefacts
Beatriz Villarroel, Lars Mattsson, Hichem Guergouri +4
In this paper, we present a simple strategy to identify Non-Terrestrial artefacts \citep[NTAs;][]{Kopparapu} in or near geosynchronous Earth orbits (GEOs). We show that even the sm…
Launching the VASCO citizen science project
Beatriz Villarroel, Kristiaan Pelckmans, Enrique Solano +25
The Vanishing & Appearing Sources during a Century of Observations (VASCO) project investigates astronomical surveys spanning a time interval of 70 years, searching for unusual and…
Self-Calibration Methods for Uncontrolled Environments in Sensor Networks: A Reference Survey
Jose M. Barcelo-Ordinas, Messaud Doudou, Jorge Garcia-Vidal +1
Growing progress in sensor technology has constantly expanded the number and range of low-cost, small, and portable sensors on the market, increasing the number and type of physica…
Multiple Benefits through Smart Home Energy Management Solutions -- A Simulation-Based Case Study of a Single-Family House in Algeria and Germany
Marc Ringel, Roufaida Laidi, Djamel Djenouri
From both global and local perspectives, there are strong reasons to promote energy efficiency. These reasons have prompted leaders in the European Union (EU) and countries of the…
Indexing and querying color sets of images
Djamal Belazzougui, Roman Kolpakov, Mathieu Raffinot
We aim to study the set of color sets of continuous regions of an image given as a matrix of rows over columns where each element in the matrix is an integer from $[1…
Memory-efficient and Ultra-fast Network Lookup and Forwarding using Othello Hashing
Ye Yu, Djamal Belazzougui, Chen Qian +1
Network algorithms always prefer low memory cost and fast packet processing speed. Forwarding information base (FIB), as a typical network processing component, requires a scalable…
Fully Dynamic de Bruijn Graphs
Djamal Belazzougui, Travis Gagie, Veli Mäkinen +1
We present a space- and time-efficient fully dynamic implementation de Bruijn graphs, which can also support fixed-length jumbled pattern matching.
Lempel-Ziv Decoding in External Memory
Djamal Belazzougui, Juha Kärkkäinen, Dominik Kempa +1
Simple and fast decoding is one of the main advantages of LZ77-type text encoding used in many popular file compressors such as gzip and 7zip. With the recent introduction of exter…
Optimal Las Vegas reduction from one-way set reconciliation to error correction
Djamal Belazzougui
Suppose we have two players and , where player has a string and player has a string and none of the two players knows the other's string. Ass…
A framework for space-efficient string kernels
Djamal Belazzougui, Fabio Cunial
String kernels are typically used to compare genome-scale sequences whose length makes alignment impractical, yet their computation is based on data structures that are either spac…
