Abstract:

The proliferation of non-expensive commercially available renewable energy systems along with the regular interruption of electrical energy from local power producers has resulted in more DIY (do-it-yourself) enthusiasts. Many of these enthusiasts are from the lower to middle-income classes and thus seek to empower themselves to purchase and install a basic off-grid renewable energy system. It's crucial to emphasize the significance of acquiring a wiring certificate for the electrical setup. National standards, quality management, and human lives are all at risk, so this step cannot be overlooked. However, several components need to be connected in the most efficient and effective way, thereby promoting safety and efficiency. The purpose of this study is to evaluate different electrical connections between two of the main components, the battery (storage device) and the solar charger (or an inverter) to enable an informed decision regarding the optimal type of connection. An experimental setup is used to gather empirical data for seven different electrical connections. The worst type of connection is a solid 1,5 mm cable with battery clamps (or clips) that results in a higher voltage drop of 0,42 V when compared to the ideal type of connection that is a solid 2,5 mm cable with unsoldered crimped lugs. It is recommended that every DIY enthusiast working with electrical connections purchase a non-expensive crimping tool to effectively connect lugs to the correct wire diameter required for their application.

Abstract:

The growth trend and increasing global population are leading to new healthcare challenges that require prompt and effective solutions to meet the clinical demands. Currently, three-dimensional (3D) printing is emerging as a rapidly advancing technology to produce metal implants and other biomedical applications. This method creates intricate designs with biomimetic characteristics in a shorter timeframe, enabling healthcare providers to meet the needs of their patients better. This study thoroughly analyzes the demand and manufacturing methods for biomedical implants, particularly metal bio-implants. It also delves into biomaterials used in additive manufacturing, accompanied by a comprehensive bibliometric study covering scientific production by country, highly cited nations, productive authors, collaboration networks, and source rankings. The paper further investigates top author contributions, affiliations, and trends, featuring various analytical tools, such as co-citation networks, keyword co-occurrence analysis, and reference publication year spectroscopy, culminating in presenting key findings through insightful field plots. The current study uses network analysis and scientometric methodologies to analyze data taken from the Scopus journal database, which includes articles from the period between 2014 and 2023, to accomplish this goal. Through this analysis, the article aims to offer valuable insights into the relevance and real-world implications of previous research on the additive manufacturing of metal bio-implants.

Abstract:

This research primarily presents a model involving R-serial service channels connected to S non-serial service channels. Feedback mechanisms are applied to the serial queues, while balking and reneging behaviors, triggered by urgent calls/messages or customer impatience, are analyzed in both serial and non-serial queues. After developing the queuing model, the system’s differential-difference equations are formulated in a compact form, and their solutions are derived by reducing them to the steady-state form for unlimited waiting capacity. Marginal probabilities and mean queue lengths are calculated to evaluate the system's performance in this scenario.

Abstract:

Partial differential equations are essential to every branch of science and engineering. They are regarded as the fundamental components of the majority of mathematical and physical simulations with practical uses. Numerous partial differential equations may be useful in the description of a physical phenomenon that could help in a deeper comprehension of its behaviour. The importance of PDEs has drawn more attention in recent years, which motivates researchers to solve these equations analytically and numerically. In this study, we propose a new hybrid technique for solving partial differential equations arising during liquid drop formations. The proposed hybrid technique is the combustion of double Elzaki transform and the classical Adomian decomposition method. To illustrate the simplicity and accuracy of the proposed scheme, some experimental work has been carried out.

Abstract:

The article is devoted to the actual problem of studying the dynamic response of bent plate structures with reinforcement represented by rigid metal profiles. Such structures can be used in pedestrian bridges or other span structures. A finite element model is built by using the example of a pedestrian bridge slab with reinforcement in the form of steel T-shape profiles. Deformations of concrete, reinforcement, and rigid reinforcement bars are described by a system of solid and shell finite elements, that take into consideration modern models of physical, geometric, and structural nonlinearity. The dynamic impact is modeled at low speed in two variants. The first is a blast load is applied in the middle of the span according to a symmetrical scheme, and the second pursuant to an asymmetric scheme. The structural and inertial damping of vibrations of the damaged system is taken into account. In this case, an implicit integration method is used. The time variation of the dynamic load implies a residual mass of the impacting body that vibrates with the slab structure after the onset of impact. The bond between concrete and stiff rebar is evaluated by the level of cohesion stresses in the vicinity of the profile with maximum strains. The finite element model is verified with a full-scale experiment in which a slab with rigid reinforcement is built and tested. Numerical studies have shown that asymmetrical loading can have a more negative effect on the structure than symmetrical loading, with structure deflections varying by up to 42%. As a result, the effectiveness of experimental theoretical modeling of the dynamics of such structures is shown, which can be used for both typical and individual designs.

Abstract:

Wireless communication in marine environments is hindered by the unique properties of seawater and the rugged ocean floor. In contrast to land-based communication, underwater conditions are distinct due to the specific characteristics of seawater. This research explores the potential of Network Function Virtualization (NFV) to enhance the monitoring of seaweed farms and underwater properties. As seaweed production is vital for the development of nutritional products, biochemical compounds, and pharmacological research, optimizing its monitoring is crucial. The goal of this study is to leverage NFV to support various aquatic activities. To achieve this, a chain of Virtual Network Functions (VNFs) is proposed to manage service flows, capitalizing on the advancements in NFV. The research employs both simulation and analytical Stochastic Network Calculus (SNC) models to evaluate key performance indicators, including delay bounds, throughput, packet delivery ratio, and energy utilization. Notably, the SNC-based NFV model outperforms simulation results, demonstrating superior performance and potential for improved packet delivery and throughput.

Abstract:

It is well known that methods of pattern synthesis reported in the open literature are mostly conventional. The methods include either standard distribution, empirical techniques, or analytical techniques. Every method has its own advantages and disadvantages regarding the overall pattern structure. The pattern structure is characterized by the main lobe and the side lobe behavior in the case of the sum pattern. On the other hand, difference patterns are the patterns characterized by the two different lobes and side lobe structures. Sequentially generating sum and difference patterns is advantageous in IFF radar applications. To simplify the design procedure and improve the pattern characteristics, an attempt is made to use random weights as amplitude excitation. Interestingly, useful results are obtained. The sum and difference are designed using the random approach and are presented in the sinθ domain for the arrays of dipoles and microstrip elements. The results are helpful for the array design depending on the applications and user requirements.

Abstract:

COVID-19 infection is particularly dangerous for individuals with comorbidities such as kidney disease and diabetes due to weakened immunity. While the pandemic has impacted people of all ages and socioeconomic backgrounds, those with underlying medical conditions are more susceptible to severe outcomes. However, the role of vaccination in the co-infection dynamics of COVID-19 among diabetic patients is not well-represented in the literature. This study examines the unique challenges presented by the co-infection of COVID-19 in individuals with diabetes, focusing on disease transmission dynamics. We employ a mathematical modeling approach using a seven-compartment model that incorporates vaccination and comorbidities like diabetes to analyze the dynamics of COVID-19 outbreaks. Analytical investigations were conducted to demonstrate the solutions' existence, boundedness, positivity, and sensitivity. After calculating the basic reproduction number, we performed a stability analysis of the model's equilibrium points. Our findings indicate that when the reproduction number is less than unity, the disease-free equilibrium is both locally and globally stable. Furthermore, as the vaccination rate increases, the incidence of COVID-19 and its co-infections with diabetes decreases. These results suggest that effective disease treatment strategies should consider the potential impact of vaccination on the co-infection of COVID-19 in diabetic patients.

Abstract:

Power transformers play an important role in the efficient delivery of power to consumers. Their failure leads to significantly higher losses and maintenance costs. Therefore, it is essential to have an optimal maintenance strategy in place for the transformers. However, to design an effective maintenance strategy, real failure data of the transformers need to be collected and studied to identify the failure patterns. To facilitate the analysis presented in this paper, five years of real failure data of a transformer system is collected from a power distribution company. The best-fit distribution for the failure times data of the system is found using AIC, BIC, and LKV values. Useful reliability parameters of the system are evaluated using the Maximum Likelihood Estimation and Rank Regression Method. Life data analysis is performed to estimate the reliable life, mean time to failure, and remaining lifetime of the entire system and its subsystems.

Abstract:

This paper presents a novel approach for solving 2D mathematical models arising in applied sciences, specifically focusing on 2-dimensional time-fractional order Klein-Gordon (TFKGE) and sine-Gordon equations (TFSGE) using the Sumudu transform-homotopy perturbation method (STHPM). The amalgamation of the Sumudu transform with the homotopy perturbation method provides an effective analytical technique for tackling these time-fractional order partial differential equations. The solutions obtained illustrate the precision and efficiency of the method, offering valuable insights for modelling complex physical systems. In this study, we also solve the same numerical problems using the variational iteration method and perform a comparative analysis of the results. This study advances the application of fractional calculus methods to challenging problems in theoretical and applied physics.

Abstract:

Life tables are used in many fields in demographic and health research They represent an important indicator of death in society. There are two types of life tables; complete life tables are based on the age at death based on single-age categories and are obtained using a comprehensive survey method. The second type is the abbreviated life tables which are based on the age at death of five-year age groups and are obtained by the sample survey method. In this research, the survival function was estimated for the data obtained from the Central Statistical Organization, social and Economic Survey of the Family in Iraq (IHSES II) using parametric methods (the principle of Maximizing Entropy method (POME), and maximum likelihood method (MLE)), as well as the use of A non-parametric approach, the kernel smoothing method (KS), the compared between the estimation methods using (RMSE) and (MAPE). One of the most important conclusions was the emergence of a preference for the (POME) method for the five-age groups, but in the case of the single-age groups, the (KS) method is the best.

Abstract:

A_G = (N, A, σ, μ) be a anti fuzzy graph. A partition of N(A_G) Π = {D₁, D_{2, ….,} D_k} is a regular anti fuzzy partial domatic partition of A_G if (i) for each D_i, < D_i > is an anti fuzzy regular and (ii) D_i is an anti fuzzy dominating set of G_A. The maximum fuzzy cardinality of a regular anti fuzzy partial domatic partition of A_G is called the regular anti fuzzy partial domatic number [RAPDN]of A_G and it is denoted by  Also these numbers are determined for various anti fuzzy graph. In this work, random r- regular anti fuzzy graph, regular partial domatic number in anti fuzzy graphs, regular partial anti domatic number in anti fuzzy graphs are introduced. Some bounds for anti fuzzy domatic numbers are discussed.
