Published: January 2024

Sign language is a vital mode of communication for deaf people, yet it presents a significant barrier when interacting with those who do not understand it. The advent of technology has paved the way for innovative solutions to bridge this communication gap. This abstract explores the development and implications of a smart glove designed for sign language translation (SLT). The primary aim of this study is to create a wearable device, the Smart Glove, capable of recognizing and translating sign language gestures into text or speech. Key objectives include designing a lightweight and ergonomic glove prototype, developing machine learning algorithms for sign language recognition, implementing real-time translation capabilities, evaluating the glove's accuracy and usability, and assessing the potential impact on facilitating communication for deaf people. The Smart Glove utilizes only one sensor, flex sensors, to capture hand movements and gestures. These data inputs are processed through a custom-built machine learning model trained on a comprehensive sign language dataset. Preliminary results indicate a high accuracy rate in recognizing sign language gestures, with an average recognition rate of over 90% across a diverse set of signs. While challenges such as expanding gesture recognition and refining translation algorithms remain, this technology offers a promising solution to break down communication barriers and enhance the quality of life for those who rely on sign language.

This study investigates the nanoparticle shape effects of aligned magnetohydrodynamics (MHD) mixed convection flow of Cu-Al2O3/water-EG Jeffrey hybrid nanofluid over a stretching vertical plate. Five different shapes of nanoparticles which are spherical, cylindrical, blades, bricks, and platelets are considered in this study. The governing equations in the form of Partial Differential Equations (PDEs) had been reduced to nonlinear Ordinary Differential Equations (ODEs) by using similarity transformation. The solver bvp4c in MATLAB software was applied to numerically solve the dimensionless governing equations towards the physical parameters which are aligned angle of magnetic field, interaction of magnetic field, mixed convection, Deborah number, volume fraction of nanoparticles, and nanoparticle shape factor. The effects of nanoparticle shapes and other relevant thermophysical parameters on fluid velocity, temperature, skin friction coefficient and Nusselt number are discussed in tables and figures. In comparison of all shapes, this study found that blade shaped nanoparticles have the highest values of skin friction coefficient and Nusselt number. The parameters blobid0.pngblobid1.pngblobid2.png and blobid3.png decrease the velocity profiles but increase the temperature profiles.

A closed cavity facade (CCF) is “a sealed, non-ventilated cavity with an automated shading device that, at its simplest, consists of double or triple glazing on the inside and single glazing on the outside”. The dynamic properties of this technology enable the fluid control of solar energy and daylight entering the structure. Several CCF designs were investigated in EnergyPlus and DesignBuilder, and the outcomes were compared to the present state (a single-glazing unit (SGU) with grey coating). The investigation was founded on a case study of a Penang Island, Malaysia, condominium. Comparing CCFs with traditional SGU systems reveals significant thermal performance and occupant comfort enhancements. CCF configurations performed well throughout the year, with maximum operational temperature reductions 40–91% better than traditional SGUs in Malaysia's humid tropical climate. Further investigation revealed that the glass coating and sun shading capabilities substantially contribute to reducing the interior temperature and enhancing the comfort of the building's occupants. The greatest performance was achieved by combining a nanocoating (83/58) and an E-low coating (83/23) (Tvis/Tsol) with a Venetian blind. In light of this, it is essential to carefully consider which coatings to use when installing CCF in such conditions. In all of these regards, the study concentrates on the fact that developing and implementing suitable combinations of a new closed-cavity facade for Malaysia's climate can result in substantial gains. The results demonstrate that building operational temperatures and comfort can be enhanced, highlighting the need for innovative glazing technology.

Published: January 2024

Latent fingerprints are used to identify specific individuals during a forensic investigation. Fingerprints provide a clear and concise means of identifying an individual and their history. Traditional techniques for fingerprint analysis include metal powder and magnetic powder dusting; fluorescent dye staining; iodine fuming; vacuum metal deposition and many more. There are several issues with the conventional technologies now in use, including their sensitivity, contrast, background interference, toxicity and complexity. In this study, the cyanoacrylate fuming technique was combined with enhancing agents such as metallic and rare earth minerals to increase the visibility of latent fingerprints in a quick and easy approach. The vapours of ethyl 2-cyanoacrylate react with the fingerprint's natural compounds, increasing the contrast of the impression. Therefore, fingerprints are visible to the human eye after being treated with cyanoacrylate. Rare earth europium oxide was also used to improve the fingerprints. The fingerprints were sprayed with a mixture of europium oxide. Images of the fingerprint samples were taken and they were evaluated. Cyanoacrylate treatment and europium oxide deposition both enhanced the visibility of fingerprints. In contrast to the cyanoacrylate-treated sample, the europium oxide-deposited specimen stood out more clearly. Hence, rare earth elements improved the visibility of hidden fingerprints.

A study that was carried out to analyses the movement and behavior of a vertically infinite plate with a parabolic beginning velocity profile in an unsteady flow scenario, taking into account numerous elements such as rotation, chemical reaction, and the Dufour effect. The investigation included evaluating heat readings from the plate as well as accumulation levels in its surroundings. The inverse Laplace technique was used to solve the governing equations. The research looked at two fundamental governing flow constraints: rotation and diffusion, velocity, temperature (Dufour), and how they affect the speed, temperature, and accumulation of a vertically oriented plate. These flow parameters' effects on mass and heat transfer proportions were also graphically represented using Matlab R 2020a. The study's findings were supported by referencing and aligning with earlier research.

Published: January 2024

Stenosis refers to the narrowing of blood vessels caused by atherosclerosis, which can lead to serious circulatory problems by obstructing blood flow and mass transfer to other organs and tissues in the body. The objective of this investigation is to numerically examine the mass transfer of blood flow in a stenosed bifurcated artery using COMSOL Multiphysics, based on the finite element method. The study takes into account the geometry of a bifurcated artery with stenosis present at the mother and daughter arteries. The blood vessel is modeled as a two-dimensional (2D) rigid wall, and the blood flow is assumed to follow a non-Newtonian Carreau fluid model, being incompressible, laminar, and steady. The continuity equation, momentum equation, and mass transfer equation, along with boundary conditions, will be solved using COMSOL Multiphysics based on the finite element method. The simulation results show that the formation of recirculation zones, as indicated by streamline patterns and mass concentration, can significantly impact the severity of stenosis and Reynolds numbers. Thus, individuals exposed to such recirculation zones may be at risk of developing cardiovascular diseases.

The effects of the variation of radiation and fluid characteristics on the flow, heat transfer, and mass transfer of a non-Newtonian Casson fluid at a vertical permeable stretched sheet are explored. We focus on the assumption that the behavior of the particles in the fluid is sensitive to both temperature and species diffusion, and we investigate their combined impacts. By using an appropriate similarity transformation, the governing nonlinear partial differential equations are converted into a system of highly nonlinear coupled ordinary differential equations. We apply a semi-analytical method for different physical parameters to solve the resultant system with proper boundary conditions. By employing the optimal homotopy analysis method (OHAM), which allows for the regulation and modification of the convergence zone, we are able to derive analytical solutions for the dimensionless velocity, temperature, and concentration fields. Our findings demonstrate that, compared to the homotopy analysis approach (HAM) proposed by Liao [1], OHAM solutions are more accurate approximations of the precise solutions for large values of the independent variable. By plotting the residual errors and comparing them to results in the literature, we can ensure that our analytical solution is correct for certain edge situations. Our method was validated by the comparison, which showed a high degree of agreement. Due to the presence of permeability parameter the velocity profile decreases, whereas the temperature and concentration profile increases. Since radiation parameter is directly connected to the free stream temperature, increasing values of radiation parameter, the thermal boundary layer thickness gets enhanced.

Authors: Su Hian Ho  , Yit Yan Koh  , Chong Lye Lim  , Lip Kean Moey
Published: January 2024

The analysis of heat transfer problems can be highly complex due to factors such as temperature, position, and time. Most heat transfers are typically two-dimensional as conduction is often negligible in the third dimension. Two-dimensional heat conduction problems can be solved analytically or numerically. In steady-state conditions, the Laplace equation can be applied to solve two-dimensional heat conduction problems analytically, in which the separation of variables method is used to solve the Laplace equation under fixed boundary conditions to determine the temperature at a specific point. The Laplace equation plays a significant role in the solution of heat transfer problems, as it demonstrates the behavior of linear and non-linear equations in the computational fluid dynamics domain. Despite their inability to provide exact results at any point, numerical methods are superior to analytical methods when handling complex geometries with various boundary conditions. This project involves the development of a computational code using MATLAB to solve two-dimensional steady-state heat conduction problems using Gauss-Seidel iterations. Comparing analytical solutions from Excel with numerical solutions from MATLAB and ANSYS, specifically the developed MATLAB code, revealed an accuracy level of 99.902% for the Laplace equation. An analysis of the produced code from MATLAB found that it could solve two-dimensional steady-state heat conduction across different combinations of materials while allowing users to specify initial and boundary conditions to produce a contour plot similar to ANSYS.

Published: January 2024

Utilization of membrane reactors for biodiesel production has been an alternative to conventional batch reactors. The membrane in the reactor acts as a separation layer, preventing the formation of by-products and allowing the desired biodiesel product to pass through. This can improve yields and reduce waste, making the process more environmentally friendly and economically viable. This study aimed to analyze the fluid flow and velocity profile inside the membrane reactor and determine the volume fraction of biodiesel. The modeling and simulation of the fluid flow of biodiesel in a membrane reactor was carried out using SOLIDWORK and ANSYS software. Using a Eulerian-Eulerian two-fluid model, multiphase simulations were carried out. Three different temperatures, 333 K, 338 K, and 343 K, were used in the simulation. The results have found that at 333K, the biodiesel production in the membrane reactor shows the best flow characteristics compared to reaction temperatures of 338 K and 343 K. Additionally, the highest volume fraction can be predicted at the temperature of 333K. Further research and simulation study can be implemented to explore the effects of inlet velocity and reaction time on the fluid flow pattern of biodiesel inside the membrane reactor.
A Review on the Influence of Additive Blended Biodiesel to the Performance and Emission Characteristics of Heavy-Duty Diesel Engines
Authors: Ahmad Jais Alimin  , Olawale Kazeem Babalola
Published: January 2024

Modern industrial society is heavily dependent on energy. The amount of energy needed to sustain a society increases as the world's population grows and transportation systems improve. However, the stringent emissions regulations enacted to control the number of harmful exhaust pollutants from heavy-duty diesel engines are likely to gradually phase out internal combustion engines that run solely on petrochemical fuels. This challenge puts constant pressure on researchers to seek improved fuel technologies that meet emission standards while reducing costs and emissions. In this paper, the impact of biodiesel blends, with or without additives was found to have both positive and negative effects on heavy-duty diesel engines. Biodiesel blends with additives such as 50% biodiesel 400mg/l additive and 100 % biodiesel 500mg/l additive have the potential to reduce emissions of harmful pollutants such as particulate matter (PM), carbon monoxide (CO), and hydrocarbons (HC). However, the impact on nitrogen oxide emissions is less clear and may depend on engine type and operating conditions. Regarding engine performance, additive biodiesel blends exhibited lower power and torque output and slightly lower fuel consumption than conventional diesel. On the other hand, non-additive biodiesel blends such as 5%, 10%, and 20% biodiesel in conventional diesel showed higher nitrogen oxide emissions and fuel consumption, but a reduction in HC and CO emissions. Overall, the use of additives in biodiesel blends can improve certain properties, such as cold weather performance and oxidation stability but the effect largely depends on engine design, operating conditions, and the percentage of additives used. Hence, more research is needed to fully understand the effect of biodiesel blends and additives on heavy-duty diesel engines and optimize their use for maximum benefits.

Polymers can be utilized for a wide variety of applications since they are lightweight and inexpensive, and their mechanical qualities are usually more than enough. Polymers often undergo a petrochemical production process and have a relatively lengthy elimination time. Green chemistry and green production are crucial in today's technology, which relies increasingly on non-toxic polymers made from natural ingredients. Biopolymers are a type of organic polymer that can break down naturally and pose no threat to human health or the environment. Here, we will take a quick look at the polymer structures that go into making eco-friendly composites in the future. Important polymer types and engineering studies for material manufacturing have been uncovered as a means of avoiding green production's negative effects on the environment. Possible future use of biopolymers as binders in composite materials and their effects on the environment.

The flow and heat transfer past a moving wedge in a hybrid nanofluid is studied. A set of governing equations is transformed into ordinary differential equations using the similarity transformation. The resulting equations are then solved using bvp4c solver in MATLAB. The effects of the wedge angle parameter and nanoparticle volume fraction parameter of Al2O3-Cu/water on the skin friction coefficient and heat transfer characteristics are investigated. It is found that increasing the wedge angle parameter and Cu nanoparticles volume fraction gives rise to the skin friction coefficient and heat transfer on the surface. Further, dual solutions exist when the wedge moves in the opposite direction with the free stream.

Cells in battery pack for electric vehicle are typically connected in series to meet system voltage requirement. In series connection, each cell will experience identical amount of current drawn, therefore the amount of heat generation for each cell will be relatively similar. Nevertheless, this depends on the cell internal resistance which causes joule heating. To mitigate increase in temperature in the pack, cooling system is necessary. Forced air cooling is the most straightforward cooling system as it pulls cool air from inside the vehicle cabin, and the air will be channeled through cooling routes in the battery module. Typically, the cell located close to the inlet of the cooling system gets the maximum cooling rate, and the cooling capacity reduces as air passes towards the last cell in the module. Two cooling designs are explored in which air velocity is varied by changing the cross-sectional area of inlet air whilst keeping the same mass flow rate. This causes the inlet air velocity to change, to which the airspeed for a small air inlet will be higher than a larger inlet. It shows that higher air speed promotes better cooling only at the first and last cell in the module with a temperature gradient up to 15°C. A battery module with a higher cross-sectional area provides a more uniform heat transfer rate whereby the individual cell temperature is relatively similar with 50% more consistent than the smaller cross-sectional area. This demonstrates that having a higher air speed is not the key attribute in determining the cooling factor of a battery module/pack.

Published: January 2024

The world restriction of fossil power sources reserves and its side effect on the environmental pollution have impelled strongly using the photovoltaic technology as alternative renewable energy sources. The essential problem is the difficulty of importing and installing solar panels without having a fully knowledge about its effectiveness in the climatic conditions of the university site. Hence, the motivation of this study is to investigate the operational efficiency of the PV system in the Iraqi environmental conditions by modelling, controlling, and simulating the system using MATLAB/Simulink program. The proposed model has been driven based on the principle mathematical equations that depict the behaviour of the PV solar system. The proposed model is designed to affect with the sunlight irradiance, ambient temperature, AC loss, DC loss, the temperature of the panels’ surfaces, and the efficiency of the used inverter. Preliminary results showed a strong correlation between sunlight irradiance and ambient temperature with the power generated by solar panels. Thus, these two parameters are chosen as the major inputs to the model. While, the electrical output power and the accumulative energy are set as the output of the simulated model. The study investigates the performance of the proposed model at the hottest day and coldest day throughout the year 2022. The results proved that the system generates more energy during the summer than in the winter due to the strength and a long period of the radiation falling on the ground during this season. Moreover, the investigation study evidenced that the system efficiency decreases as ambient temperatures increase. As the results, the cumulative energy during one day decreased by around 41.366% from the summer to winter. Finally, the authors recommend installing the suggested solar cell system in Iraq because its effectiveness was theoretically proved.

Published: January 2024

This study investigates the melting heat transfer in MHD flow that occurs when the flow is past a stretched sheet. With the use of the boundary layer concept, a set of non-linear ODEs is derived from a system of PDEs of motion and energy. After transforming the non-linear ODEs and their boundary conditions into dimensionless form with the use of appropriate similarity conversions, the equations are then numerically solved by employing the MATLAB inbuilt solver bvp4c method in conjunction with the shooting methodology. Through the use of a variety of charts and tables, the authors analyze and describe in depth the effects that relevant factors have on a variety of flow fields. As melting factor (Me) increases, it is discovered that the effect of Me on fluid temperature and velocity distributions decreases. Williamson parameter and inclined magnetic profile are shown to have decreasing impact on velocity and momentum parameter. After that, the findings are compared with the earlier published findings in limited situations of the issue, and it is discovered that they are in exceptional specify with those findings.

Published: January 2024

Objective: Cancers are currently adjudged as a hindrance to achieving a desirable life expectancy in most countries. The high mortality rate from ovarian cancer is a result of the pathology not having specific symptoms, late presentation, and lack of proper screening that results in its diagnosis in the advanced stages. The study aimed to determine the prevalence, clinical presentation, and outcome after the management of patients with ovarian cancer seen in the tertiary institution.
Methodology: It was a retrospective study. Relevant information was extracted from the case files of the patients with histologically confirmed ovarian cancer. The data obtained were analysed using Statistical Package for Social Sciences (SPSS) statistical software, version 23.
Results: Thirty-two cases of ovarian cancer were admitted during the period under review. This constituted 21.0% of gynaecological malignancies managed in the hospital during the study. The mean age of the ovarian cancer patients was 50.94±12.01 years with 56.25% of the patients being postmenopausal. The majority of the patients (62.4%) have 3 or more parous experiences with 53.1% of the patients presenting with advanced disease. Epithelial ovarian cancer was the most common histological variant. The treatment modality was surgery and chemotherapy. However, 65.7% of patients defaulted from initiating or completing chemotherapy.
Conclusion: The study revealed that patients presented in the late stage of the disease and a bulk of them did not complete the treatment. There is a need to lobby Governments to subsidize cancer treatment, especially in the area of chemotherapy treatment.

Published: January 2024

Objective: Acne, particularly severe forms, may impair quality of life. This study aimed to determine the prevalence of acne, its severity, and its impact on the quality of life among young people in Nigeria.
Methods: We conducted a cross-sectional survey of 1017 systematically selected undergraduates in a Nigerian University using a 24-item self-administered questionnaire. We derived the proportions and means of participants’ characteristics and computed the crude and specific (age, sex, and location of residence) prevalence. We then conducted bivariate analysis and used binary logistic regression analysis to evaluate the relationship between the report of acne and the dermatologic quality of life. The level of significance was set at 5%.
Results: About half (539; 53.0%) of the respondents were females, while 478 (47.0%) were males with mean ages of 16.6 (±1.2) and 16.8 (±1.4) (p = 0.004) respectively. The prevalence of self-reported acne was 61.3% (58.2-64.3). Participants reporting acne were four times more likely to perceive an impairment in dermatologic quality of life (AOR: 4.18 [2.77-6.33]). The perceived severity of acne was statistically related to the dermatologic quality of life. Participants with moderate (AOR: 3.05 [2.19-4.25]) and severe (AOR: 7.96 [3.12-20.16]) acne were at increased odds of impairment of dermatologic quality of life compared to those with no or mild acne.
Conclusion: The self-report of acne and its severity are associated with diminished quality of life independent of age and sex. The management of acne among young people should include strategies to improve their perceived quality of life.
