A Machine Learning-based Secured and Energy-efficient Data Transmission in Mobile Ad-Hoc Networks (MANET)

Mobile hoc networks (MANET) are wireless networks of mobile devices that set up Data Transmission (DT) links independently without a fixed framework. Because topology changes constantly, MANET lines are often interrupted and out of balance. So, making sure that DT works well and reliably while also making good use of network resources is a problematic issue that MANET needs to solve. The suggested solution is to create a DT method to deal with these issues. This method aims to improve DT by sending data as quickly as possible while using as little time. As learning examples, the suggested method uses a range of mobile gadgets. Support Vector Machine (SVM) classes are trained to be weak groups. Supervised SVM can sort the surrounding nodes into groups with better link quality and lower energy use. The results of weak learners are combined to create a robust classifier, which guarantees that the data transfer works well. An experimental test checks the amount of power used, the packet transfer rate, the time it takes, and the output. The number of mobile nodes and data packages will be changed during the analysis.

Li-Sn Alloyed Layer Containing Artificial SEI on Li-Metal Anode for Superior Lithium Metal Batteries: Development and Understanding of Anode/Electrolyte Interfacial Phenomena

Modern civilization and cutting-edge technologies and tools are highly dependent on energy storage devices and demand efficient and long-lasting high-energy-density storage devices. Lithium metal batteries have surpassed their competitors concerning energy density due to their inherent high specific capacity (3860 mAh/g) and the lowest electrochemical potential (-3.04 V vs. standard hydrogen electrode), proving to be one of the most favorable energy storage devices for smart and mobile gadgets, electric automobiles, grid storage, etc. However, safety-threatening and performance-decay challenges associated with lithium metal anodes, such as lithium dendrite formation, uncontrolled parasitic reactions between Li-metal and electrolyte, low coulombic efficiency, dead Li-formation, etc., restrict its employment in practical batteries. The root cause of the dendrite formation is poor Li-ion conductivity of bulk lithium metal, which results in an uneven electric field distribution, leading to non-uniform Li deposition/stripping upon repeated charge/discharge. Herein, a facile chemical reduction process is being opted to fabricate a highly Li-ion diffusive Li-Sn-based artificial SEI layer on the lithium metal surface to prevail over the above-mentioned issues. Therefore, upon careful concentration investigation of reactants, 25 mM precursor concentration (SnCl4 in EC: DMC in 1:1 volume ration) demonstrated the best electrochemical performance, revealing a cumulative capacity of over 700 mAh/cm2 at a current density of 1 mA/cm2 for 1 h in a symmetric cell. Physical characterizations (XRD and SEM-EDS) showed a thin layer containing Li-Sn alloys along with LiCl formed at the lithium metal surface. Possessing high Li-ion diffusivity, Li-Sn alloyed hybrid anode illustrated a gradual decrease in the charge transfer resistance on increasing the concentration, thus, lower overpotential in symmetric cells, in contrast to pristine Li-metal. However, an increase in the electrical resistance has been observed on increasing the precursor concentration due to the presence of the insulating LiCl phase in the protective layer. Moreover, in-situ optical microscopy demonstrated more uniform and on-surface Li-deposition for the hybrid electrode, whereas mossy and dendritic growth on bare Li-metal. Full cells prepared with Li-Sn alloyed anode against NMC532 cathode illustrated stable cycling up to 150 cycles; contrastingly, the cell with pristine Li-metal showed a drastic capacity fade just after 100 cycles, demonstrating the inclination towards safer lithium metal batteries.

Enhancing Autonomous Vehicle Technology with YOLOv8

The system's products and features form the basis of the product search process. By splitting up and recording huge photos of low-quality images in high resolution, its performance may be easily balanced As machine learning advances quickly, powerful tools are capable of to take on more intricate, sophisticated, or profound features to address issues with legacy tools.. This project offers a new way to detect vehicles, pedestrians and traffic signs using only publicly available data. Because research requires long-term photographs (such as images shot in direct sunlight), it is challenging to incorporate research into the data, and confidence training is uncommon due in part to the nature of the data. We presents modification of the YOLOv8 model for training to improve accuracy. In that model, a number of constants and lossy components were employed. The reason behind this is that YOLOv8 works well utilizing mobile gadgets and requires less RAM management. Unity also provides additional support to simplify the conversion process.

An Optimal Modified Bidirectional Generative Adversarial Network for Security Authentication in Cloud Environment

In the contemporary world, mobile appliances are connected to a cloud environment for balancing the wide range of data that is created. Because of the shortage of security and authentication, Cloud Computing (CC) is vulnerable to many attacks and security risks in the communication environment. Therefore, security is more significant for secure data transmission. In this paper, we proposed the modified Bidirectional Generative Adversarial Networks based on the Artificial Hummingbird (AH) algorithm (modified BiGAN-AH approach) within the cloud environment for security authentication. The ML-based BiGAN classifier is utilized to identify attacks during the session set-up stage. To reduce the loss, the cross-entropy function is computed in the training stage of BiGAN for estimating divergence. The discriminator’s parameters are predetermined while training both the encoder and generator. For enhancing encryption difficulty, the integration of the Substitution Permutation (SP) network and Feistel combination are used in the Symmetric Key Block Cipher (SKBC) algorithm. Data security is provided by the SKBC. To enhance the efficiency of GAN in detecting attacks, the Artificial Hummingbird (AH) algorithm is utilized for optimizing hyperparameters. The experimental outcomes reveal that the proposed approach reached 93.75% accuracy, 92.41% precision, 93.85% recall value, and a 93.52% F1 score.

Design of improved write and read performance 12T sram cell with leakage power control technique

Currently, memory occupies nearly eighty-five percent of the allocated chip area. Integrated electronics, such as workstations and mobile gadgets, need quick memory systems that use low power. Scaling issues make it impossible to obtain low-power and resilient SRAM cells, which are critical for Internet of Things (IoT) devices, using CMOS semiconductor technology. New nanoscale technologies, like FinFET, are being proposed as a substitute for CMOS in SRAM architecture. The study introduces a novel 12T SRAM cell design using FinFET technology, including differential writing and single-ended reading operation facilitated by write-read circuitry. The cell employs a write-assist-based approach to enhance the stability of reading and writing operations accordingly. In addition to differential writing architectures, single-ended reading decreases power use, while stacking transistors and minimizing read bit-line leakage minimizes leakage power utilization. The cell's performance has been evaluated utilizing a Cadence Spectre simulator featuring 18-nm FinFET technology and compared to current SRAM architectures at a supply voltage of 0.8 V. PVT variations are conducted to evaluate the efficiency of the suggested SRAM design. The reading and writing stability of the new SRAM cells has been enhanced by a minimum of 10 % when compared with the current counterparts. A 15 % decrease in power consumption has been seen in the suggested design compared to conventional SRAM cells of the same technology.

Utilization of Mobile Network Infrastructure to Prevent Financial Mobile Application Account Takeover

The Covid-19 pandemic has kept almost everyone at home and forced them to perform online activities using their mobile gadgets. Penetration of the Internet and mobile use is increased as lockdowns or restrictions on meeting face to face are getting used to. This has become a new market for cyber criminals to carry out their actions, such as spreading Social Engineering, sending Phishing, doing Account Takeover, and ending in theft of money in Financial Mobile Applications. Application protection with OTP SMS and Magic Link SMS still has vulnerabilities, with several examples of cases that have occurred. For this reason, this problem was raised to find a solution using the Mobile Network Infrastructure. The method used is to compare the congruence between the phone numbers registered in the application and the phone numbers used. Every time a user signs in or signs up, the Financial Mobile Application will perform Mobile Network Verification to cellular operators via API. Verification is carried out by utilizing the header enrichment in the background of the application process that was installed on the user's smartphone or tablet to the Mobile Network Verification Server. The Financial Mobile Applications can then determine whether the user is using a valid or invalid telephone number. Therefore, the target account cannot be taken over because the cyber criminal's mobile device does not have the phone number attached to the victim’s mobile device. This proof is carried out with four test case scenarios with the sign-up and sign-in processes on the same phone number and different phone numbers between devices and applications. It is hoped that this kind of protection model can reduce losses experienced by users of Financial Mobile Applications due to Account Takeover.

Second language vocabulary learning in the digital era: Ten reasons it should be on the go!

Word learning is a key component in second language learning and one that L2 learners often find laborious. With the advent of mobile technology in recent years, research on mobile-assisted vocabulary learning has uncovered the immense potential mobile devices (namely smartphones and tablets) have for providing L2 learners with opportunities for effortless learning of L2 lexis. To this end, we pinpoint ten reasons why L2 learners should abandon traditional pen-and-paper-based methods of word learning and shift instead to a digital mobile word learning environment that fully utilizes the virtues of mobile learning. The role of mobile applications (apps) dedicated to word learning is hence stressed as such apps represent the core basis of mobile-assisted vocabulary learning. For EFL learners to entertain a more manageable and less time-consuming word learning experience, we emphasize the role of EFL teachers in calling their learners’ attention to the ten reasons we underscore in this article to help encourage those who are still into conventional word learning and have not yet explored learning words via mobile gadgets to make the digital shift at once.

Development of an improved SSL/TLS protocol using post-quantum algorithms

The development of Internet technologies together with mobile and computer technologies have formed smart technologies that allow the formation of both cyber-physical and socio-cyber-physical systems. The basis of smart technologies is the integration of wireless channel standards with mobile and computer protocols. 4G/5G technologies are integrated with various web platforms, taking into account the digitalization of services in cyberspace. But the SSL/TLS protocol, based on the hybridization of symmetric encryption algorithms with hashing algorithms (AEAD mode), which is supposed to provide security services, is vulnerable to “Meet in the middle”, POODLE, BEAST, CRIME, BREACH attacks. In addition, with the advent of a full-scale quantum computer, symmetric and asymmetric cryptography algorithms that provide security services can also be hacked. To increase the level of security, an improved protocol based on post-quantum algorithms – crypto-code constructions is proposed, which will ensure not only resistance to current attacks, but also stability in the post-quantum period. To ensure the “hybridity” of services, it is proposed to use the McEliece and Niederreiter crypto-code constructions (confidentiality and integrity are ensured) and the improved UMAC algorithm on the McEliece crypto-code construction. Taking into account the level of “secrecy” of information, it is suggested to use various combinations of crypto-code constructions on different algebraic geometric and/or flawed codes. The use of crypto-code constructions not only provides resistance to attacks, but also simplifies the formation of a connection – the parameters of elliptic curves are used to transmit a common key. This approach significantly reduces the connection time of mobile gadgets and simplifies the procedure of agreement before data transfer

Non-syndromic multiple teeth impaction - case report

Tooth eruption is а continuous process by which developing teeth move through the soft tissue, oral epithelium, jaw bones and overlying mucosa, to emerge in the oral cavity, contact the teeth of the opposing dental arch, and enable teeth functional position in mastication. Abnormal tissue interactions during tooth development may be potentially revealed as ectopic tooth development, ectopic eruption or tooth impaction. In human dentition, permanent tooth impaction is relatively common. Impaction of the first permanent molar is an uncommon condition and few cases are reported in the literature. It is essential to diagnose and treat the impacted permanent molars as early as possible because treatment at a later stage is usually more complicated due to the tendency of malocclusion to increase with time. We report a case with impaction of the maxillary first permanent molar and impaction of all, maxillary and mandibular permanent second molars. This condition compromise masticatory function. Unilateral mastication also compromises the function of temporomandibular joint. The aim of this case-report was to present orthodontic treatment with Schwartz removable appliance in a patient with maxillary left-side impaction of the second premolar, first molar and second molar. The goal of the first phase was positioning the maxillary first molar into the dental arch with good bone and periodontal support. The surgical intervention, operculectomy, was done and the orthodontic treatment started by traction of the first molar with elastic ligature attached from the bonded bracket to the mobile appliance. One month later the tooth movement was obvious.
