 Abstract

Dry Hand Washing Machine represents an innovative approach to hand hygiene, utilizing a fog-based disinfection system to significantly minimize water consumption while ensuring effective cleaning. This system integrates a water reservoir containing a safe herbal disinfectant, which is transformed into fine fog using a specialized fogging mechanism. The mist uniformly covers the entire surface of the hands within seconds, helping dissolve soap and remove contaminants thoroughly. Compared to traditional hand washing methods, this approach dramatically reduces water usage, making it a more sustainable and eco-conscious solution for hygiene in public and private settings. The machine operates on an Atmega-based controller that enables manual adjustments, including setting the duration of fog exposure for each user. Additionally, the incorporation of solar power enhances energy efficiency and supports autonomous operation. IoT integration allows real-time monitoring and tracking of sanitizer levels and system performance. This smart, water-efficient disinfection method promotes environmental sustainability while improving hygiene standards and public health outcomes.

 Abstract

The stability of a system is basically regionalized networks, also known as micro grids, must be able to operate independently by cutting off their connection to the main grid in order for a system to stay stable. Customers' reliability can be raised by providing a more robust power supply. Due to reversed energy flow from distributed generator units, regional fluctuations, temporary micro grid modes, significant frequency discrepancies in electrically isolated mode operation, as well as financial and supply demand uncertainties, consistency, dependability, and security are in fact with micro grids In order for a system to remain stable, regionalized networks known as micro grids must be able to function independently by cutting off their connection to the main grid. By offering a stronger power supply, the dependability of consumers can be increased.

 Abstract

Wireless Power Transfer (WPT) has proven to be a revolutionary technology for electric vehicle (EV) charging, allowing contactless and efficient energy transfer. This paper reports the design and development of a better WPT system using a high-frequency inverter and resonant inductive coupling to deliver higher power transfer efficiency. A MATLAB/Simulink model is created using source-side and vehicle-side compensation networks, rectifiers, and battery charging logic. Performance of the system is analyzed over a range of different coil separations by varying mutual inductance values while holding coil parameters steady. Contrary to traditional anticipation that power transmission drops off as distance increases, simulation yields only a slight gain in transmitted power at larger separations. This aberrant behavior can be ascribed to the intrinsic characteristic of the resonant inductive coupling circuit that dynamically varies its operation as per variations in coupling strength while providing high energy transfer via tuned resonance at high frequency. The simulated model of this design reveals trustworthy performance, stable SOC process, and high efficiency, hence qualifies as an excellent candidate for practical EV wireless charging applications.

 Abstract

Effect of earthquake can be very hazardous to the structure influenced by these forces. There are many traditional methods for protection of structure against earthquake effects. But there are some disadvantages in these methods. Increasing strength and stiffness are some of the traditional methods. But they lead to higher sections and result in uneconomic design. To overcome these disadvantages associated with the traditional method, many vibration-control measures, called structural control, have been studied and remarkable advances in this respect have been made over recent years. This paper describes the effect of use of steel bracing, dampers, base isolator (lead rubber bearing), combination of steel bracing with dampers and the combination of base isolator with steel bracing in a structure subjected to earthquake motion. The structure is designed in ETABS 2016 and then bracings, dampers, base isolator and some combinations are applied respectively in 6 different models and results are compared. Force of ground motion that is earthquake force is applied to structure by using seismic coefficient method. Base isolated structure gives improved performance against seismic vibrations than conventional structure. The essential characteristics of base isolation system are isolation, energy dissipation, and restoring mechanism. It is shown that under design conditions, all base isolators can significantly reduce the acceleration transmitted to superstructure. Bracing and dampers are also useful reduction of storey drift and base shear.

 Abstract

This literature survey explores the evolution of credit information sharing, credit information bureaus in contemporary financial systems that support well-informed lending choices and improve credit market efficiency, and their effects on borrowers. The research looks at credit information exchange and credit bureaus in India and other nations. The results demonstrate the growing significance of credit information bureaus as a result of the widespread use of credit reports. Employers use it to find information about a candidate's credit history, and insurance companies, car manufacturers, landlords, and employers use it to assess a client's credit worthiness. Therefore, it is evident that the current financial system depends on the exchange of credit information. The results show that for high-quality borrowers, exchanging credit information lowers loan duration and the interest rate spread. It was discovered that credit information bureaus had a favourable and substantial effect on banks' credit performance, globally.

 Abstract

Surrogacy represents a complex intersection of law, ethics, and human desire. As advancements in assisted reproductive technologies (ART) expand the possibilities of family creation, the practice of surrogacy continues to provoke profound questions about autonomy, consent, commodification, and trans-national justice. This paper explores the evolving legal landscapes and ethical controversies surrounding surrogacy, drawing on comparative perspectives from jurisdictions such as the United States, United Kingdom, India, and Ukraine. It examines the tension between commercial and altruistic models, the role of consent and economically asymmetrical arrangements, and the implications of cross-border surrogacy on citizenship, parentage, and regulation. Emphasising the need for coherent and rights based legal framework. The paper argues that ethical surrogacy must prioritise the dignity and agency of all parties involved - specially the surrogate and the child -while recognising the legitimacy of diverse family building aspirations. This paper delves into the various ethical and legal challenges surrounding surrogacy, with a focus on international and domestic perspective. It examines regulation of surrogacy, the ethical concerns it raises, the legal rights of all the parties involved, and the complexities in managing cross-border arrangements. Additionally, the research delves into the issue of exploitation, the commodification of reproduction and the need for international legal consistency that regulate surrogacy procedures. This paper has tried to examine surrogacy through a dual lens: a mechanism for reproductive empowerment and as a practice vulnerable to exploitation. It interrogates the normative framework that governments across different legal systems, evaluate the ethical implications of divergent regulatory models and considers the rights and interest of all stakeholders, including the surrogate intended parents and children. Thus, this paper seeks to illuminate the necessity for legal harmonisation and ethical clarity in the governance of surrogacy, specially in an era, defined by globalisation and technological advancements. The research ultimately advocates for internationally harmonised legal standards, grounded in reproductive justice, human rights, and informed consent. The study concludes with recommendations for reform in both ethical and legal frameworks that will make it safe and secure for the parties involved.
