Abstract Software Defined Networking (SDN) being an emerging network control model
is widely recognized as a control and management platform. This model provides efficient
techniques to control and manage the enterprise network. Another emerging paradigm is
edge computing in which data processing is performed at the edges of the network instead
of a central controller. This data processing at the edge nodes reduces the latency and
bandwidth requirements. In SDN, the controller is a single point of failure. Several security
issues related to the traditional network can be solved by using SDN central management
and control. Address Spoofing and Network Intrusion… More >

Abstract This study was conducted to enable prompt classification of malware, which
was becoming increasingly sophisticated. To do this, we analyzed the important features
of malware and the relative importance of selected features according to a learning model
to assess how those important features were identified. Initially, the analysis features
were extracted using Cuckoo Sandbox, an open-source malware analysis tool, then the
features were divided into five categories using the extracted information. The 804
extracted features were reduced by 70% after selecting only the most suitable ones for
malware classification using a learning model-based feature selection method called the
recursive feature… More >

Abstract Illicit drug use is a significant problem that causes great material and moral
losses and threatens the future of the society. For this reason, illicit drug use and related
crimes are the most significant criminal cases examined by scientists. This paper aims at
modeling the illegal drug use using the Atangana-Baleanu fractional derivative with
Mittag-Leffler kernel. Also, in this work, the existence and uniqueness of solutions of the
fractional-order Illicit drug use model are discussed via Picard-Lindelöf theorem which
provides successive approximations using a convergent sequence. Then the stability
analysis for both disease-free and endemic equilibrium states is conducted. A… More >

Abstract In today’s world, smart phones offer various applications namely face detection,
augmented-reality, image and video processing, video gaming and speech recognition.
With the increasing demand for computing resources, these applications become more
complicated. Cloud Computing (CC) environment provides access to unlimited resource
pool with several features, including on demand self-service, elasticity, wide network
access, resource pooling, low cost, and ease of use. Mobile Cloud Computing (MCC)
aimed at overcoming drawbacks of smart phone devices. The task remains in combining
CC technology to the mobile devices with improved battery life and therefore resulting in
significant performance. For remote execution, recent studies… More >

Abstract A mathematical model consisting of a system of four nonlinear ordinary
differential equations is constructed. Our aim is to study the dynamics of the spread of
COVID-19 in Nigeria and to show the effectiveness of awareness and the need for relevant
authorities to engage themselves more in enlightening people on the significance of the
available control measures in mitigating the spread of the disease. Two equilibrium
solutions; Disease free equilibrium and Endemic equilibrium solutions were calculated and
their global stability analysis was carried out. Basic reproduction ratio ( More >

Abstract The idea of fractional derivatives is applied to several problems of viscoelastic
fluid. However, most of these problems (fluid problems), were studied analytically using
different integral transform techniques, as most of these problems are linear. The idea of
the above fractional derivatives is rarely applied to fluid problems governed by nonlinear
partial differential equations. Most importantly, in the nonlinear problems, either the
fractional models are developed by artificial replacement of the classical derivatives with
fractional derivatives or simple classical problems (without developing the fractional
model even using artificial replacement) are solved. These problems were mostly solved
for steady-state fluid problems.… More >

Abstract The Internet of Medical Things (IoMT) will come to be of great importance in
the mediation of medical disputes, as it is emerging as the core of intelligent medical
treatment. First, IoMT can track the entire medical treatment process in order to provide
detailed trace data in medical dispute resolution. Second, IoMT can infiltrate the ongoing
treatment and provide timely intelligent decision support to medical staff. This
information includes recommendation of similar historical cases, guidance for medical
treatment, alerting of hired dispute profiteers etc. The multi-label classification of
medical dispute documents (MDDs) plays an important role as a front-end process… More >

Abstract The communication in the Millimeter-wave (mmWave) band, i.e., 30~300
GHz, is characterized by short-range transmissions and the use of antenna beamforming
(BF). Thus, multiple mmWave access points (APs) should be installed to fully cover a
target environment with gigabits per second (Gbps) connectivity. However, inter-beam
interference prevents maximizing the sum rates of the established concurrent links. In this
paper, a reinforcement learning (RL) approach is proposed for enabling mmWave
concurrent transmissions by finding out beam directions that maximize the long-term
average sum rates of the concurrent links. Specifically, the problem is formulated as a
multiplayer multiarmed bandit (MAB), where mmWave… More >

Abstract In modern physics and fabrication technology, simulation of projectile and
target collision is vital to improve design in some critical applications, like;
bulletproofing and medical applications. Graphene, the most prominent member of two
dimensional materials presents ultrahigh tensile strength and stiffness. Moreover,
polydimethylsiloxane (PDMS) is one of the most important elastomeric materials with a
high extensive application area, ranging from medical, fabric, and interface material. In
this work we considered graphene/PDMS structures to explore the bullet resistance of
resulting nanocomposites. To this aim, extensive molecular dynamic simulations were
carried out to identify the penetration of bullet through the graphene and… More >

Abstract It is a very difficult task for the researchers to find the exact solutions to
mathematical problems that contain non-linear terms in the equation. Therefore, this article
aims to investigate the viscous dissipation (VD) effect on the fractional model of Jeffrey
fluid over a heated vertical flat plate that suddenly moves in its own plane. Based on the
Atangana-Baleanu operator, the fractional model is developed from the fractional
constitutive equations. VD is responsible for the non-linear behavior in the problem. Upon
taking the Laplace and Fourier sine transforms, exact expressions have been obtained for
momentum and energy equations. The influence… More >
