Asymptotic Stability of Solutions to a Class of Second-Order Delay Differential Equations

Mathematics, 2021
We consider a class of second-order nonlinear delay differential equations with periodic coefficients in linear terms. We obtain conditions under which the zero solution is asymptotically stable. Estimates for attraction sets and decay rates of solutions

On the Cauchy Problem for Pseudohyperbolic Equations with Lower Order Terms

Mathematics, 2023
We consider a class of strictly pseudohyperbolic equations with lower order terms. The solvability of the Cauchy problem in Sobolev spaces with special weights is established. The uniqueness of the solution is proven and estimates are obtained.

Blocking Linear Cryptanalysis Attacks Found on Cryptographic Algorithms Used on Internet of Thing Based on the Novel Approaches of Using Galois Field (GF (2³²)) and High Irreducible Polynomials

Applied Sciences, 2023
Attacks on the Internet of Things (IoT) are not highly considered during the design and implementation. The prioritization is making profits and supplying services to clients. Most cryptographic algorithms that are commonly used on the IoT are vulnerable

An Application of the Khumbelo Function on the Camellia Algorithm to Prevent Attacks in IoT Devices

IEEE Access, 2023
Camellia is an encryption algorithm implemented in many Internet of Things (IoT) devices. However, intruders attack the Camellia cipher using Substitution Box (S-Box) distinguishers.

Asymptotic Properties of Solutions to Delay Differential Equations Describing Plankton—Fish Interaction

Mathematics, 2021
We consider a system of differential equations with two delays describing plankton–fish interaction. We analyze the case when the equilibrium point of this system corresponding to the presence of only phytoplankton and the absence of zooplankton and fish

Preventing Differential Cryptanalysis Attacks Using a KDM Function and the 32-Bit Output S-Boxes on AES Algorithm Found on the Internet of Things Devices

Cryptography, 2022
Many Internet of Things (IoT) devices use an Advanced Encryption Standard (AES) algorithm to secure data stored and transmitted during the communication process. The AES algorithm often suffers DC (DC) attacks. Little has been done to prevent DC attacks,

Performing neutrality in ‘post’-conflict Burundi

Nordic Journal of African Studies, 2020
The reintegration of ex-combatants has a number of dimensions: economic, social, and political. This article explores what reintegration, defined as the shedding of the ex-combatant identity, means for the political participation of former combatants in

Ev/ اَوْ Bağlacının İfadeye Kattığı Farklı Anlamların Türkçe Meâllere Aktarımı Sorunu

Cumhuriyet İlahiyat Dergisi, 2021
Dilde kullanılan kelimelerin genel olarak bir asıl/temel manası bulunmasının yanı sıra, bu kelimeler zamanla temel anlamının dışında yeni ve özel anlamlar kazanır. Ortaya çıkan bu anlamlar temel anlamdan bütünüyle bağımsız olmaz.

Documenting Attachment: 'Affective border control in applications for family reunification'

Nordic Journal of Migration Research, 2019
From 2002 to 2018, Denmark was the only country in the world to enforce a migration law demanding that couples seeking family reunification in Denmark documented their combined “attachment” to the Danish nation.
