A remarkable dynamical symmetry of the Landau problem
Tekin Dereli, Philippe Nounahon, Todor Popov
We show that the dynamical group of an electron in a constant magnetic field is the group of symplectomorphisms . It is generated by the spinorial realization of…
Detrimental 2-3 Hybridisation in Ni Nanosheets Supported on Strontium Dioxide for Catalytic H Production, Necessitating Thickness Optimisation
Kabir S. Suraj, M. Hussein N. Assadi
We employ accurate density functional theory calculations to examine the electronic structure of three Ni/SrO nanostructures containing single-layer, bilayer and four-layer Ni…
Applying of the Extreme Value Theory for determining extreme claims in the automobile insurance sector: Case of a China car insurance
Daouda Diawara, Ladji Kane, Soumaila Dembele +1
According to the Chinese Health Statistics Yearbook, in 2005, the number of traffic accidents was 187781 with total direct property losses of 103691.7 (10000 Yuan). This research a…
Artificial Intelligence-Based Smart Grid Vulnerabilities and Potential Solutions for Fake-Normal Attacks: A Short Review
J. D. Ndibwile
Smart grid systems are critical to the power industry, however their sophisticated architectural design and operations expose them to a number of cybersecurity threats, such as dat…
A Fast Algorithm for Heart Disease Prediction using Bayesian Network Model
Mistura Muibideen, Rajesh Prasad
Cardiovascular disease is the number one cause of death all over the world. Data mining can help to retrieve valuable knowledge from available data from the health sector. It helps…
Overview description of the Gambian GABECE Educational Data and associated algorithms and unsupervized learning process
Ousmane Saine, Soumaila Dembélé, Gane Samb Lo +1
As the first paper of a series of exploratory analysis and statistical investigation works on the Gambian \textit{GABECE} data based on a variety of statistical tools, we wish to b…
A Supervised Hybrid Statistical Catch-up System Built on Gabece Gambian Data
Tagbo Innocent Aroh, Ousman Saine, Soumaila Dembélé +1
In this paper we want to find a statistical rule that assigns a passing or failing grade to students who undertook at least three exams out of four in a national exam, instead of c…
Tele-operative Robotic Lung Ultrasound Scanning Platform for Triage of COVID-19 Patients
Ryosuke Tsumura, John W. Hardin, Keshav Bimbraw +6
Novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a pandemic of epic proportions and a global response to prepare health systems worldwide is of utmost…
Pair emission from a relativistic domain wall in antiferromagnets
Gen Tatara, Collins Ashu Akosa, Rubén M. Otxoa de Zuazola
Magnon emission and excitation by a relativistic domain wall at a constant velocity in antiferromagnet is theoretically studied. A pair emission due to a quadratic magnon coupling…
Mobile-Based Deep Learning Models for Banana Diseases Detection
Sophia Sanga, Victor Mero, Dina Machuve +1
Smallholder farmers in Tanzania are challenged on the lack of tools for early detection of banana diseases. This study aimed at developing a mobile application for early detection…
Topological Hall signatures of magnetic hopfions
Börge Göbel, Collins Ashu Akosa, Gen Tatara +1
Magnetic hopfions are topologically protected three-dimensional solitons that are constituted by a tube which exhibits a topologically nontrivial spin texture in the cross-section…
Statistical tests for the Pseudo-Lindley distribution and applications
Gane Samb Lo, Tchilabalo Abozou Kpanzou, Cheikh Mohamed Haidara
The pseudo-Lindley distribution was introduced as a useful generalization of the Lindley distribution in Zeghdoudi and Nedjar (2016) who showed interesting properties of their new…
Tuning skyrmion Hall effect via engineering of spin-orbit interaction
C. A. Akosa, H. Li, G. Tatara +1
We demonstrate that the Magnus force acting on magnetic skyrmions can be efficiently tuned via modulation of the spin-orbit interaction strength. We show that the skyrmion Hall eff…
Current-driven nucleation and propagation of antiferromagnetic skyrmionium
S. A. Obadero, Y. Yamane, C. A. Akosa +1
We present a theoretical study on nucleation and propagation of antiferromagnetic skyrmionium induced by spin current injection. A skyrmionium, also known as 2π skyrmion, is a vort…
Theory of chiral effects in magnetic textures with spin-orbit coupling
C. A. Akosa, A. Takeuchi, Z. Yuan +1
We present a theoretical study of two-dimensional spatially and temporally varying magnetic textures in the presence of spin-orbit coupling (SOC) of both the Rashba and Dresselhaus…
Modeling the SBC Tanzania Production-Distribution Logistics Network
Nelson Christopher Dzupire, Yaw Nkansah-Gyekye, Silas Steven Mirau
The increase in customer expectation in terms of cost and services rendered, coupled with competitive business environment and uncertainty in cost of raw materials have posed chall…
A Multi-Stage Supply Chain Network Optimization Using Genetic Algorithms
Nelson Christopher Dzupire, Yaw Nkansah-Gyekye
In today's global business market place, individual firms no longer compete as independent entities with unique brand names but as integral part of supply chain links. Key to succe…
Phase controlling current reversals in a chaotic ratchet transport
Bruno S. Dandogbessi, Omololu Akin-Ojo, Anatole Kenfack
We consider a deterministic chaotic ratchet model for which the driving force is designed to allow the rectification of current as well as the control of chaos of the system. Besid…
