<div class="section abstract"><div class="htmlview paragraph">Modern automotive systems are becoming increasingly complex, comprising tightly integrated hardware and software components with varying safety implications. As the demand for ISO 26262 compliance grows, performing efficient and consistent Hazard Analysis and Risk Assessment (HARA) across these layers presents both methodological and practical challenges. Traditional approaches often involve performing HARA for an item (where item maybe a system or a combination of systems), which can lead to update of HARA for every new feature addition in an item, which in turn may lead to analysis of same functions in multiple HARAs leading to inconsistent risk categorization, redundancy, or even conflicting safety goals. Therefore, this paper proposes a unique HARA methodology which consolidates the list of functions from various systems and performs the HARA for the grouped functions (hereby referred to as Cluster HARAs)<b>.</b> For example, Electrical power steering, Electric pump powered hydraulic steering, Electric motor assisted – hydraulic steering, have identical functions but are being analysed separately for many years which causes redundancy and results in increased effort. Once a cluster HARA is created, in case of development of a new feature/function or update of an existing feature/function, we check only for similar functions in the existing cluster HARAs and take up the corresponding safety goals. In this way, all the systems / components which has the same function, refer to the cluster HARA and no redundant HARAs are created, resulting in decreased effort from implementation point of view. In short, the proposed methodology will greatly reduce the number of HARAs that are handled across all systems. The benefits of using this methodology also involve identifying unique safety goals for each function, irrespective of how the function is implemented. When the new E/E features are developed which uses the existing vehicle functions, it simplifies the workflow by reusing the existing cluster HARAs.</div></div>

As per Sustainable Development Goals Report 2022, “Achieve gender equality and empower all women and girls,” is placed as the fifth goal of that report. It describes Gender equality as not only a fundamental human right but a necessary foundation for a peaceful, prosperous, and sustainable world. There has been progress over the last decades, but the world is not on track to achieve gender equality by 2030. As stated by Sara Blakely, “When women fulfil their potential, magic happens.” At present, empowering women is the most effective instrument for development in India. As per the National Family and Health Survey, between 2019 and 2021, it was found that India has a population of more than a billion, and that there are more women than men in the country at a ratio of 1,020 women for every 1,000 men. Despite the fact that women make up the majority of the population in India, they are not in a position to express their values. This study aims to explore, women's empowerment in the dimensions of Financial with a special focus on Women Professionals in Kumbakonam. This research examines whether professionals really attain empowerment or not. Data is collected from women professionals in Kumbakonam by applying the strata sampling method and a comparative study was made between their present and previous position. That is before they become professionals and after becoming professionals. It analyzed the economic empowerment of women professionals and their economic empowerment was evaluated with the parameters of their asset position, debt, investment, freedom to spend money on their own, etc. Throughout the work comparative study reveals their current and previous position. Percentage analysis and passed to ResNet50 to obtain the result.

<div class="section abstract"><div class="htmlview paragraph">This paper analyses technical issues encountered while charging electric vehicles using plug-in chargers. The electric vehicles are charged periodically based on charging system configuration and requirements set by the vehicle. In certain instances, the vehicle charging is interrupted, and the battery does not attain the expected state of charge. If such interruptions occur in commercial vehicles, they can delay the product or service delivery, leading to losses to the fleet owner. The charging process needs to be upgraded to deal with such situations. The charging interruptions are analyzed using logged vehicle measurement data, based on which the software and hardware in the vehicle are updated. The analysis showed that though the coupler was connected to the vehicle, the vehicle could not be charged due to an interruption. Communication error, power supply failure, component protection, component leakage, and charging facilities were identified as the causes of interruptions. This analysis was instrumental in the decision to upgrade the charging system in electric vehicles.</div></div>

An efficient and adroit surveillance system is im-perative in the fast-paced digital world, with a monumental rise in video-based surveillance systems for security and monitoring. The pandemic has created the need for effective surveillance and made it more relevant than ever before. The AI-based surveillance system proposed in this paper is capable of performing the traditional functions of a surveillance system and checking if a person is wearing a mask and if his temperature is below a certain threshold. The proposed surveillance system is a video-based surveillance system capable of logging people who are not wearing a mask or whose temperature is not below a specified value. This system is implemented with Raspberry Pi as the central hub for processing, extracting, and analyzing the video stream from a camera. The proposed system aims to identify the mask on people by using a cascade classifier generated by Machine learning techniques, thus mulling down the effects of external factors (lighting condition, position, etc.) that affect the performance of a traditional video surveillance system.

"The current paper describes a new low-cost sensing system that employs a load cell embedded in the tool carriage assembly of an open hardware fused deposition modelling (FDM) 3D printer. The sensor system automates the process of detecting and compensating for inconsistencies in the flatness of the bed's surface relative to the nozzle. A sensor system prototype was implemented in an FDM 3D printer to determine contact between the bed and the tool's nozzle. The system was then used by a software routine in the machine's microcontroller firmware to automate the bed levelling. Finally, an automated bed leveling system was observed and analyzed its behavior. The sensor system and the Automatic Bed Levelling (ABL) process are evaluated by observing the bed surface obtained via a load cell bed probe. From the machine controller, the ABL process takes 75 seconds. The bed levelling system uses the load cell probe to automate the manual bed levelling process, saving time. The current work reduces error and improves the efficiency of 3D printer operation. It also reduces the amount of time needed to operate and improves print quality. "

<div class="htmlview paragraph">The comfort of the passenger inside the vehicle is the primary concern of NVH analysis. The noise sensitivity inside the passenger cabin is studied by performing the acoustic sensitivity analysis. In general, acoustic sensitivity analysis using MSC-Nastran[<span class="xref">1</span>] involves coupling the grids on the boundary of the acoustic cavity with the structure grids of the body structure.</div> <div class="htmlview paragraph">In MSC-Nastran[<span class="xref">1</span>], the coupling between the structure and acoustic cavity can be checked prior to the analysis by using a match grid table and the interface check forces.</div> <div class="htmlview paragraph">It has been found that even though the match grid table indicates that all the boundary grids of the acoustic cavity are coupled with the structure grids, the interface check forces is usually quite high. Ideally, the interface checks forces at the boundary should be equal to zero (numerical zero). It has been found during the course of an internal structure acoustic analysis on a full vehicle that the quality (Jacobian and warpage) of the acoustic elements has a direct influence on the interface check forces.</div> <div class="htmlview paragraph">In order to further understand this relationship, a study has been conducted to identify the influence of element quality on the interface check forces. To start with simple regular geometry such as a cube and a sphere is considered. The study is then extended to the actual acoustic cavity of a full-vehicle model. The present paper is a discussion on the results of such a study to identify the appropriate quality criteria for elements used in such numerical analysis.</div>
