Braking dynamics of a tadpole type three-wheeler
Authors: SAHANI Medha
Published: February 2025

Abstract. Tadpole vehicles are becoming more and more common in transportation applications, so it is crucial to have a thorough understanding of their braking dynamics to ensure the highest level of performance and safety. Their unusual three-wheel design, tadpole vehicles offer a unique set of opportunities and challenges when it comes to braking systems. By implementing a modified mathematical model designed especially to capture all aspects of braking dynamics in tadpole vehicles, this paper fills a gap in the frame of existing literature. As a practical testbed, a tadpole vehicle was utilized to collect empirical data for braking parameters. This specific tadpole vehicle has Alto brakes installed. The implemented mathematical model achieved a higher level of accuracy and precision by integrating the actual data. Traditional braking equations were modified and improved upon in order to take into account the unique characteristics of a tadpole vehicle. A complex 3-degree-of-freedom Simulink model was developed to provide a thorough understanding of straight-line braking dynamics in tadpole vehicles. This model made it possible to investigate in-depth how different factors interact to affect the braking performance. The simulation produced precise and thorough results providing insights into the unique advantages and difficulties presented by tadpole vehicle configurations during straight-line braking.

Authors: MALYADRI T.
Published: February 2025

Abstract. Asbestos roof sheets are deleterious for health and for the environment. Breathing in asbestos fibres can cause lung cancer and mesothelioma. When it comes to environmental impacts, asbestos contaminates the air, water and the soil. To avoid these circumstances, composite fibre reinforced plastic roof sheets can be used as a substitute to asbestos roof sheets. This composite roof sheet includes Kevlar, Basalt and Glass particles as fibres; epoxy as resin and SiO2 and TiO2 as Nanofillers. This paper includes the systematic procedure of design and fabrication of a composite roof sheet. The design of the roof sheet involves a corrugated structure reinforced with six layers of fibre sheets. The fabrication of the roof sheet includes a mould of 10-feet by 4-feet dimensions. The regional Hyderabad dealers provided the nanoparticle material used in this investigation. In this experiment, materials such as Araldite LY556 epoxy resin, Ardur HY951 hardener, basalt (B), glass (G), and kevlar were used (KV). The density of the Araldite LY556 epoxy resins is between 1.16 and 1.20 g/cm3 and between 10,000 and 12,000 at 25C. (cps). The K- 6 hardener's feature is that it can outperform forecasted market demand at increased permeability and room temperature. The density and flashpoint of K-6 hardener are 110 C and 0.98 and 0.99 g/cm3, respectively. With an average particle size of 30 nm, the TiO2 region has a 50 + 15 m2, 80 in antae crystal, and 200 crystals. The particles range in size from 62 to 70 nm and are 98% pure. The reverse osmosis and polymerization bonding between the molecules are improved by the addition of these nanofillers. The slurry is coloured with grey pigment to give the roof sheet colour. To make the mixture more resistant to heat and sunlight exposure, UV lite powder is sprinkled over the mixture.

Authors: KATGERI Anirudh R.
Published: February 2025

Abstract. Variable Stiffness Actuators (VSA) are modern mechanical systems, designed to exhibit varying stiffness/compliance characteristics in response to the external forces. It is an essential sub-system in the fields of robotics, biomechanics and prosthetics. Key elements of VSAs are springs, cables, pneumatic units, variable transmission mechanisms etc., playing a crucial role in providing a reliable and effective performance. A Miniature type straight and curved leaf-springs are more commonly used elements. The development and demonstration of varying stiffness characteristic of non-tapered curved beam in the form of S-springs, as a part of actuators has attained major recognition in the recent days. Present work is on demonstrating the varying stiffness characteristics of a tapered-curved beam, demonstrating modified varying stiffness range. A generalized and simplified mathematical model to estimate the deflection and corresponding stiffness of the tapered-curved beam for varying orientation is developed using Castigliano’s theorem. A limited parametric study for a tapered-curved beam is conducted and the results are presented along with the non-tapered curved beam. The initial results for non-tapered curved beam published in the literatures are compared with the present approach. Analytical results are validated with the results obtained by numerical approach. Numerical analysis is conducted on Ansys platform. It can be extended for a cost-effective design in robotics actuator’s design. The results are plotted in graphs to compare the deflection of tapered beams of different geometries for easy understanding of varying deflection and stiffness. Tapered curved beam can be incorporated in actuation mechanism such as gripping, pick and place or other robotic applications, requiring specific stiffness that can be altered through rotating the curved beam.

Investigating the impact of numerical models on buckling and dynamic response of underwater metal and CFRP capsule
Authors: THOTA Jayanth Datta
Published: February 2025

Abstract. The present study aims to differentiate various numerical models in terms of mesh quality and geometry in predicting the response of an underwater shell made of aluminum subjected to buckling and free vibrations. A pressure of 1MPa for buckling and a 6-mode modal analysis were considered. Two different numerical geometries are considered, one with solids and the other with a solid-shell combination. Two different mesh qualities with the same element size are developed for solid geometries without and with slicing the solids at geometric discontinuities to enhance the element quality. From the buckling and dynamic response of the structure from both the solid models, variations in buckling factor and frequencies from the modal analysis were observed due to changes in element quality for the same size. The observed increase of around 7% in the mesh quality between the converged sliced model and the corresponding non-sliced model highlights the impact of mesh quality and modeling approach on the accuracy of the simulation. Extending the analysis by replacing the aluminum shell casing with carbon-epoxy composite (CFRP) introduces an additional layer of complexity due to the material properties and behavior of CFRP compared to aluminum. The comparison between the results obtained from the sliced model with CFRP and aluminum shell casings will provide insights into how the change in a material affects the structural response under buckling and modal analysis. The entire process is executed using ANSYS software.

Authors: GOHAD Rushikesh
Published: February 2025

Abstract. Artificial Neural Network was used to develop the model for estimating Young’s modulus of cast aluminum alloys. MATLAB ANN Toolbox was used to develop the feed-forward backpropagation model. The cast aluminum alloys with their alloying elements percentage are given as input to develop the model while Young’s modulus of the respective alloy is given as output for the ANN model. The model was developed by using three training algorithms namely Lervenberg-Marquardt (LM), Bayesain-Regularization (BR) & Scaled conjugate gradient (SCG). Various trials were taken to develop the best suitable model. The evaluation was carried out by using Mean Squared Error (MSE) and Coefficient of correlation(R). After evaluation by MSE and R, Bayesain-Regularization showed the least error and gave the best predicted results.

Authors: TRIVEDI Ajay
Published: February 2025

Abstract. An experimental investigation on effect of friction stir lap welding (FSLW) process parameters on mechanical and microstructure of AA6082-O welds is presented. Three process parameters namely tool rotational speed (1000,1400 & 2000 rpm), tool shoulder diameter (18, 20 & 22 mm) and tool traverse speed (28, 56 & 80 mm/min) are considered. Experiments are planned as per L9 Taguchi array. Data are analyzed in terms of S/N ratio and Analysis of Variance (ANOVA). Tensile shear strength is observed in the range of 11.79 MPa to 29.23 MPa. It is observed that tool diameter and tool rotational speed are most significant factors affecting tensile shear strength. Optimum levels of process parameters (28 mm/min tool traverse speed, 18 mm tool diameter and 1400 rpm tool rotational speed) is decided based on analysis of experimental data. Using optimum process parameters for friction stir lap welding of Al alloys improved quality of welded joints can be made. Use of optimized parameters will improve the performance of the products in terms of durability and load carrying capacity.
Importance of different filler material on residual stress mitigation in dissimilar joining of nuclear grade T/P92 and AISI304 steel
Authors: MEENA Pavan
Published: February 2025

Abstract. Joining of dissimilar ASMW SA335 P92 and AISI304 steel produces residual stresses due to solidification and cooling incompatibilities. Thermal conductivity and specific heat variations with temperature, affect heat transfer rates. Differential cooling behaviors, thermal expansion, and Poisson’s ratios are the main reason behind inducement of residual stresses after joining. This study employs finite element method to thoroughly investigate the causes and mechanisms underlying the generation and distribution of residual stresses while using the different filler materials. The findings indicate that the primary sources of welding-induced longitudinal residual stress (σL) are the thermal shrinkage and phase transformation process. Additionally, apart from these two processes, the quenching process contributes to the production of transverse residual stress (σT). It was observed that the maximum (σL) typically reaches the yield strength (σy) of the base metal (BM) at ambient temperature.

Published: February 2025

Abstract. Stress analysis encompasses three primary methodologies: analytical, experimental, and computational. While analytical methods offer theoretical insights, they often fall short in addressing complex problems. Experimental approaches, though thorough, demand substantial time and resources. Computational analysis presents itself as a promising alternative as experiments can be simulated in a virtual environment using computer simulations with the added advantage of easy modification of material or shape properties. This paper presents a comprehensive study of the use of FEA in conducting computational stress analysis for static and fatigue stresses on dental crowns. This paper explains the methods used at each stage of conducting an FEA study.

Published: February 2025

Abstract. This study explores the use of biogas and nanoparticle-doped biodiesel as sustainable options for compression-ignition (CI) engines, driven by worries about the depletion of fossil fuels and their environmental effect. This study provides a complete overview of the interconnected impacts of engine load, nickel oxide nanoparticle doping rate, Neem biodiesel mix ratio, and biogas flow rate on the performance and emissions of a CI engine. Response Surface Methodology (RSM) provides a means to comprehend and conduct organized experiments, while Artificial Neural Network (ANN) is capable of capturing intricate non-linear interactions. Both models undergo thorough statistical analysis utilizing several assessment metrics to reveal the impact of each input parameter on important outcomes. This study also extensively explores the important field of optimization, focusing on the progress achieved in RSM and ANN models. RSM's desirability function optimized the output parameters at 67.45% engine load, 96.06 ppm NDR, 10.7 % BBR and 0.85 kg/h BFR, while ANN with Harris Hawks Optimization (HHO) optimized the output parameters at 67.01% engine load, 98.39 ppm NDR, 8.41% BBR and 0.846 kg/h BFR. This integrated approach offers a robust framework for enhancing the sustainability and efficiency of CI engines, presenting practical solutions for transitioning toward cleaner energy systems.

One structure utilized in commercial and industrial buildings is the gable frame. This frame is tapered with slopes on both sides, making it a sturdy and effective construction. Since the stability of the rigid frame must be ensured by using gable frames, internal forces impact the frame's stability. Additionally, gable frames are made to support various kinds of loads. By analyzing the cross-sectional area and inertia that give rigidity to the size of the beams and columns in each element, the structure may be made more flexible. The impact of internal forces on the column on changes in roof slope will be analyzed as part of this study. To analyze the effect of columns on roof slopes, gable frame modeling is done using the STAAD Pro aid program, and the profile utilized is IWF 588x300x12x12. The 5o, 7o, 10o, 15o, and 20o slope variations are used to observe the impact of internal forces that occur in shape within the column for the Load and Resistance Factor Design (LRFD) method of cross-section control calculation analysis. SNI 1727:2020 is used for cross-section checks, and 17226:2019 is used for load calculations. According to the modeling results, a considerable axial force will be produced at a slope of 20 degrees. In contrast, a lesser slope angle will result in larger compressive and tensile stress, namely at a slope of 5 degrees. The gable frame's use of slope will impact the axial force by 4%.

Fractal Learning: A Minimum Viable Instruction Approach to Democratizing and Accelerating Education
Authors: Reaves John
Published: February 2025

In an era of radical and accelerating change, traditional discipline-specific curricula and institutions are increasingly ill-suited to address the life goals of diverse learners. We suggest that equally radical approaches need to be taken in redesigning education. This paper describes a proof-of-concept workshop—termed “Fractal Learning”—that embodies a minimum viable instruction (MVI) approach. Fractal learning replaces rigid curricula with a flexible, repeatable, goal-oriented framework, leveraging technology, cloud-based resources, and metacognitive scaffolding to accelerate learning and problem-solving skills. The design elements, workshop framework, and iterative cycle are intended to be a provocative suggestion for a more democratized and personalized educational paradigm.

Authors: Stanković Nemanja , Milošević Nikola , Stanojević Bojan
Published: February 2025

This study explores the relationship between weight categories and personality traits among male judokas, focusing on psychological differences alongside well-documented physical and performance-related attributes. The aim was to compare emotional competence, personality traits and perceived self-efficacy across lightweight, middleweight, and heavyweight judo categories. The sample included 28 male judokas with over seven years of training and national competitive success, divided into lighter (n=15; -60kg, -66kg, -73kg and 81kg) and heavier (n=13; -90kg, -100kg and +100kg) categories. Psychological traits were assessed using the Emotional Competence Questionnaire, HEXACO-PI-R, PANAS, and the Perceived Social Self-Efficacy Scale. Statistical analyses included independent samples t-tests, Pearson correlations, and canonical discriminant analysis. The findings revealed significant differences in emotionality, with lightweight and middleweight judokas exhibiting higher levels compared to heavyweights. Heavier judokas displayed lower emotional expressiveness and a lower ability of managing emotions, along with reduced negative affect. In contrast, lighter judokas demonstrated higher openness to experience, conscientiousness, and cooperativeness. Additionally, conscientiousness correlated positively with age. These results highlight the need for tailored coaching approaches to address the distinct psychological profiles of judokas in different weight categories. While heavyweight judokas may require support to identify and manage latent psychological needs, lightweight athletes could benefit from enhanced emotional support.

Published: February 2025

Export promotion is used as an effective development strategy for many countries, while innovations and technologies have a major impact on the overall value and structure of exports. Exports, especially of agricultural products, have a special and greater importance for the economic development of developing countries, compared to developed countries. The subject of research in this paper is the export of the agri-food sector of the Republic of Serbia in relation to economically developed and innovative countries, and the aim of this research is to indicate the impact of the export of this sector on economic development. The OLS panel regression showed a positive impact of both the agri-food and the whole agribusiness sector on economic and sustainable development, thus confirming the research hypotheses. The Republic of Serbia and developing countries should follow the development strategies of innovative and economically developed countries. This means changing the structure and diversifying exports in order to increase the added value of products and their competitiveness on the international market. The way to achieve this is to introduce innovations in the production process and to increase productivity, which will increase the degree of processing of primary agricultural products, and create a precondition for structural transformation from primary to other sectors and economic development of countries.

Johannesburgo es la única megalópolis en el mundo que no surgió en torno a una gran fuente de agua: así empiezan muchos informes políticos sobre el suministro de agua de Gauteng. Este gesto retórico presenta los problemas hídricos actuales de la provincia como la consecuencia no deseada del crecimiento en una tierra ya de por sí árida. Pero la historia es más compleja. Witwatersrand constituye la mayor cuenca hidrográfica del sur de África. Los cursos de agua al este de la cordillera desembocan en el océano Índico, mientras que los del oeste lo hacen en el Atlántico. Comunidades y subregiones llevan trazas de agua en los topónimos afrikáans terminados en -fontein (fuente) o -spruit (manantial), cursos de agua pequeños en cierta medida, pero vitales para las comunidades y ecologías a las que sirven. Su vasta extensión da idea del extenso acuífero que se extiende por Gauteng y las provincias vecinas. Todavía en 1937, un comentarista podía describir la cresta como “bien irrigada”. Fue la aceleración de la transformación antropocénica la que creó la escasez.
Facefit: Face Shape Recognition and Styling Suggestion
Authors: Ade Sakshi
Published: February 2025

This web-based application utilizes machine learning (ML) technology to help users recognize their face shape and
make informed styling choices aimed at enhancing their overall appearance. The process begins by applying computer vision
techniques, which analyze various facial features to classify the user's face into one of seven predefined categories: round,
square, oval, heart, diamond, rectangle, or triangle. By examining specific characteristics, such as the broad forehead commonly
seen in heart-shaped faces or the balanced proportions of an oval face, the system provides a detailed, personalized face shape
assessment. Once the face shape is accurately identified, the application takes personalization to the next level by offering
tailored styling recommendations. These suggestions are designed to enhance the user’s natural beauty by aligning with their
unique face shape. For example, users with a round face may receive suggestions for hairstyles that create the illusion of
elongation, while those with a square face might be recommended glasses frames that soften their angular features. These
customized recommendations extend to accessories, allowing users to choose the best earrings, sunglasses, and other items to
complement their appearance.

This paper investigates how language is used in online media to frame the crisis surrounding undocumented immigrants in Malaysia amid a global pandemic. A 25-minute Al Jazeera documentary, “Locked Up in Malaysia’s Lockdown”, was examined following Bucholtz and Hall’s (2005) selected principles of positionality, relationality, and indexicality. The findings reveal an intricate link to identity, with the theme of ‘Us vs. Them’ being the common thread that connects to all other discourses surrounding race, class, gender, nationality, and nationalism. The findings contribute to theoretical knowledge and raise awareness of the implications of negative rhetoric against the marginalised in society.

Published: February 2025

The flood disaster that hit Malaysia for three weeks from mid-December 2021 until early January 2022 was one of the worst floods to hit the country. The role of the media is very important in providing accurate news for public understanding and then helping them make decisions related to this issue. However, the media has its agenda in constructing news for the audience based on ownership, readership and revenues. Understanding the representation of flood news is vital to explore how the media helps the community to make informed decisions when facing flood disasters through its reporting. This study aims to identify the pattern, news sources and theme of flood news reporting from 17 December 2021 to 16 January 2022 by mainstream newspaper, Berita Harian and alternative newspaper, Free Malaysia Today using qualitative content analysis. News samples (N = 210) were collected from both news portals and analyzed descriptively using SPSS software. The study’s findings show that Free Malaysia Today publishes flood news almost seven times more (87.1%) than Berita Harian (12.9%). Both newspapers emphasize the same theme which is assistance to the victims. All 210 news items are published with pictures and videos, most of which show the flood situation. Through the Agenda Setting Theory and Framing Theory, this study concludes that mainstream and alternative newspapers do not show significant differences in terms of ownership agenda and framing because the reporting pattern and theme are almost the same except for the frequency of reporting.

Screen media plays a vital role in shaping public perceptions of cancer. This article examines the Malay telefilm Hingga Jumpa Lagi (2018) and its representation of cancer’s complexities. While the telefilm effectively showcases the personal struggles of Eva, it oversimplifies the multifaceted aspects of the disease. This oversimplification risks perpetuating misconceptions and stigmatisation. Identifying crucial gaps in information, this article suggests that the telefilm lacks depth needed for comprehensive understanding. Recommendations emphasise the necessity of providing additional, accurate information within the film to dispel misconceptions.
By enhancing the portrayal’s accuracy, this approach aims to foster informed support for cancer patients and promote better societal awareness of the disease.

Social learning is a process whereby it happens in all human beings through observing, imitating, and modelling the behaviours, attitudes, and emotional reactions of others.

Tomar a palavra: mulheres, feminismos e fala pública
Authors: Braga Amanda
Published: February 2025

Nos últimos anos, em diversos países do mundo, assistimos à emergência de trabalhos que demonstraram a regularidade das práticas de silenciamento às quais estiveram – e ainda estão – submetidas as mulheres. São trabalhos que revelam o funcionamento histórico e sistemático de tais práticas, além de seus modos de atuação e da danosa naturalização de seus efeitos. Nesse cenário, o ensaio bibliográfico que apresentamos dedica-se a uma apresentação crítica do modo como os movimentos feministas problematizaram a fala das mulheres e, principalmente, agenciaram lugares de resistência às interdições que lhe foram impostas. Trata-se de um percurso que tem início no século XIX e que desagua em nossos dias, contemplando, conforme o pretendemos demonstrar, pelo menos três distintas reivindicações: primeiramente, a reivindicação do pleno exercício oratório das mulheres; na sequência, a reivindicação da oferta de um regime de escuta a tal exercício; e, por fim, a reivindicação da legitimidade daquilo que dizem as mulheres. Para tanto, o ensaio lança mão de uma vasta bibliografia feminista.
