Global Fusion of Nascent Technologies in Next -Generation Electric Vehicles models: Evolution, Developments and Regulatory Prospects
Full text linkDue to its potential to have the lowest carbon footprints on the planet, electrical vehicles, or EVs, have drawn a lot of attention globally in the period of moving towards greener and zero-emission energy generation and transportation. Climate change is currently seen as one of the main negative consequences of burning fossil fuels and traditional modes of transportation. Because Renewable Energy Sources (RESs) are variable and electric vehicles (EVs) are one of the primary means of increasing them, electrifying energy consumption is one of the most important aspects of the energy transition when considering the replacement of conventional plants with RE. This study had a comprehensive review about evolution of electric vehicles with emphasis on the information about \u27Model\u27, \u27Make\u27, \u27Electric range\u27, \u27Base MRSP\u27 and \u27Electric Vehicle Type\u27. By using EV sales data the study focussed on global trends at the continent and country level by identifying the best and worst performing countries in terms of sales. Using data-driven methods, this study investigates the EV characteristics that have a significant influence on range. Web mining was used to get a comprehensive dataset of the technical parameters of commercial EV models produced between 2013 and 2023. Regression analysis of 103 EV models showed that price is significantly impacted by top speed and efficiency. Moreover, ML algorithms were trained and tested on a data set comprising (Historical, Projection-APS, and Projection-STEPS) for a time period of 2011-2030 with a lowest mean squared error of 0.00015 and r2 of 67 percent, and MSE 4.7 and r2 of 90 percent, obtained from Adaboost and XGB indicative of the good predictive accuracy of the model. These performance parameters that were determined are useful to EV consumers to choose best EV model.
Fintech Revolution in Micro Textile Industry: A Study Focusing the Case of Punjab, India
Full text linkThe purpose; The purpose of this study is to examine the perceptions of micro-enterprises regarding the use of FinTech tools to meet their financial requirements. In the Indian context, micro-enterprises within the textile industry form a critical pillar of the economy, sustaining growth while generating significant employment opportunities. Despite facing considerable challenges—including inadequate infrastructure, limited access to institutional finance, and restricted market linkages—this sector has demonstrated remarkable growth in employment generation, investment inflows, production capacity, and overall contribution to the national GDP.
Methodology; The study adopts a quantitative research approach, collecting a total of 100 primary responses through a structured questionnaire.
Findings; The survey reveals that firms\u27 understanding of FinTech instruments, as a source of loan is fairly poor. In addition, the study\u27s data generates three unique aspects: the Banking, MSME, and FinTech aspects. Fintech is gaining recognition in the Textile business, but it is not yet pervasive. Entrepreneurs in the Textile business are in severe need of Fintech funding alternatives. Entrepreneurs are unsatisfied with the services provided by banks, but they have no alternative options for obtaining financing. Fintech is considered by the Micro Textile sector to be the finest alternative source of funding and financial support.
Originality; Numerous scholars have examined diverse dimensions of FinTech application and utilisation, as evidenced by prior research. However, there are very few studies focusing on rising nations, although their need is rather strong. This is a good effort concerning the Indian state of Punjab from a FinTech stand point on MSME’s
FinTechs and Crypto Valuation: A Comparison with Traditional Assets
Full text linkPurpose: To show how FinTechs (exchanges, payment apps, neobanks, brokers, custodians) shape crypto-asset valuation by mediating access, liquidity, settlement, and compliance, and to bridge appraisal logics from traditional assets to tokenized markets.
Methodology: I extend a multilayer valuation framework with a copula-based interdependence structure to include a FinTech intermediation layer. Traditional finance factors (L1), crypto-native fundamentals (L2), and sentiment/behavioral signals (L3) are augmented with FinTech variables, including stablecoin rails, exchange microstructure and outages, payment-app adoption, and custody/prime-broker collateral usability. Identification relies on interaction terms and event-style tests around platform launches, fee changes, outages, partnerships, and regulatory actions.
Data: Token-level prices and liquidity measures; exchange depth/spreads and outage logs; stablecoin supply/velocity; and FinTech adoption proxies (e.g., app downloads/DAU, supported fiat rails, custody features, fee tiers). Regulatory and platform news provide time stamped events. (Frequency aligned to the main specification.)
Findings: Higher FinTech intensity is associated with faster error-correction after information shocks and stronger transmission of valuation signals when stablecoin liquidity and exchange depth are high. Outages and funding frictions increase tail dependence. Adding FinTech terms improves explanatory power and stress-window accuracy without materially altering baseline coefficients.
Original contribution: The paper makes FinTech intermediation an explicit, testable layer in crypto valuation, linking platform conditions to price discovery within a transparent, regulation-ready (MiCA/SEC) and ESG-aware framework. This clarifies how appraisal paradigms from traditional assets extend to crypto when routed through modern FinTech infrastructure.
Development and Testing of Prototype-Scale Off-Grid Solar Power Generation for Electric Charging Station
Full text linkAbstract: The demand of electricity that keeps increasing necessitates additional electricity generation. The highly dependence of power generation on fossil fuels implies the intensive use of this resources that may cause them finish sooner than predicted. On the other hand, the use of fossil fuels for transportation is quite dominant. The development and use of electric transportation system is a solution for reducing fuel consumption. However, the electricity for supplying the electric transportation system is mainly from the generation system that uses fossil fuels. For further improvement, the energy supplied to the transportation system should come from the renewable energy generation. This may lead to minimum use of fossil fuels besides giving minimum effect on environment. This paper presents the development of renewable energy generation where the generated power is used to supply the storage that charges the electric bicycle. The power is generated by solar photovoltaic panels and it is saved in a battery. The charging for the bicycle is taken from the battery. The developed system is off-grid since the system may be placed in the non-electrified area. This prototype will be a role model regarding the combination of renewable energy generation and green transportation system
Numerical and Experimental Investigation of the Effects of Thin Hard Coatings on the Strength of Spur Gears
Full text linkAbstract: The use of thin films to coat mechanical components is a well-established practice. The main uses concern areas in which scratch resistance, corrosion resistance, surface hardness and particular aesthetic characteristics are required. In addition to these properties, it has been demonstrated that Physical Vapor Deposition (PVD) processes bring further benefits from a structural point of view, especially as regards fatigue and contact fatigue phenomena. In this research work, predictive models have been proposed which allow to evaluate the mechanical behavior of coated components to model the initiation and propagation of cracks. Spur gears used in the automotive and motorcycle industries were examined. Therefore, advanced numerical models were developed to accurately evaluate the stress-strain state of the components under examination, both as regards the fatigue at the tooth base and for the contact fatigue on the tooth flank. The results of the numerical models were finally compared with the results of the experimental tests to verify their accuracy
Thermoelectric Material Fabrication using Mask Image Projection Based Stereolithography Integrated with Hot Pressing
Full text linkAbstract: Waste energy harvest using thermoelectric (TE) materials will be a potential solution to the serious environmental pollution and energy shortage problems. Due to limitations of current manufacturing techniques in geometry complexity and high density, TE devices are not widely utilized in daily life to gather waste energy. 3D printing brings an opportunity to solve the fabrication limitations. In this paper, a hybrid process was developed to fabricate thermoelectric materials by integrating hot pressing with stereolithography. The mold and punch were designed and printed to fabricate thermoelectric devices used on hot water tubes via stereolithography. The Sb2Te3 powders filled the 3D printed mold in a layered manner, and each layer of powders was compacted under the pressing of punch at a certain temperature and compressive force. The polymer mold was removed after the sintering process to form the final TE components. A series of experiments were conducted to identify the optimal heating temperature and compressive force. The microstructures morphology and electrical conductivity of fabricated Sb2Te3 samples were evaluated. This research work conducted a scientific investigation into the fabrication of TE material with a hybrid process, including hot pressing and 3D printing, to solve the current manufacturing challenges, providing perspectives on developments of TE devices used in various energy harvest applications
Additive Design Mimics the Strength and Architect of Nature
Full text linkAbstract: It is believed that the best parts’ design and performance is that which mimics the creation of nature. Palm is a very good example of an extra ordinary tree which must attract the attention of engineers and designers. In contrast with other types of trees, palms have a vascular, jumble, and spongy tissue stem instead of a wooden one. This is the reason why palm trees can with stand strong hurricanes while trees cannot. The stem of a palm is composed of three main parts. Those are the main stem body, the central core, and the leaves growing from the central core in circular and axial patterns along the core. This natural combination tissues of different construction provides an extra-flexibility to the main stem, enhance the relative movement of these components, and as a result enables the palm to bend massively without any catastrophic fracture. This exceptional construction inspired the author to design and manufacture a part which mimics the most public tree at the home country. The model was additively manufactured from 316L, tested for bending with and without heat treatment, and compare with cast part of similar material and dimensions. The aim was always to achieve improved mechanical properties and performance of AM parts with complex geometry
Ballistic Energy Absorption of Thermally Aged DGEBA/TETA System and Fique-Fabric Reinforced Epoxy Composite
Full text linkAbstract: For many applications, such as vests or parts of vests, the fibers are used in fabric, mat, or mesh. Ballistic resistance properties are also improved by the development of special fabrics architectures. It is known that heat and oxygen are the main factors in the aging process of polymers. The mechanisms of aging by oxidation can be investigated by monitoring the mechanical properties of a material exposed to prolonged aging in an oven, which is called the accelerated aging process by thermal oxidation. In previous studies, the epoxy matrix composite reinforced with 40% by volume of fique fabric, already tested and with good ballistic performance, was developed and proposed for individual ballistic protection applications. However, the impact of different environmental conditions on the dynamic properties of the composite has not been studied. Therefore, the present study, for the first time, aimed to apply accelerated weathering through high temperature to the composite, as well as to the epoxy matrix, aiming to evaluate the influence of aging
Vehicle Longitudinal Control with the Sliding Mode Method Considering Uncertainty of the Model
Full text linkAbstract: In this paper, the control algorithm for longitudinal control of a passenger car that is moving on the highway and urban traffic is provided. Longitudinal dynamic equation including resisting forces acting on the vehicle presented and structural and non-structural uncertainties in the model are investigated. To control the speed of vehicles on the highway and vehicle distance control in city traffic, vehicle longitudinal control laws have been proposed. To control the speed of vehicles on the highway and in city traffic, vehicle longitudinal control laws have been proposed. In order to control the nonlinear systems, the sliding mode method which is a robust control method has been used for the design controller. The controller consists of two algorithms as speed control and distance control that their duty is done with the force generation to move the vehicle and overcome the disturbances and uncertainties using tracing of it by car. Finally, to ensure the ability of control and efficiency under different conditions, the control rules are applied to the vehicle dynamics equation
Virtual Sensor Design for Linear and Nonlinear Dynamic Systems
Full text linkAbstract: The problem of virtual sensors design in linear and nonlinear systems is studied. The problems is solved in three steps: at the first step, the linear model invariant with respect to the disturbance is designed; at the second step, a possibility to take into account the nonlinear term and to estimate the given variable is checked; finally, stability of the observer is achieved. The relations allowing to design virtual sensor of minimal dimension estimating prescribed component of the state vector of the system are obtained. The theoretical results are illustrated by practical example
