Authors: Tank Kartik , Pandey Pramod , Sharma Shashank , Mandal Sandeep , Hasan Mohammad
Published: December 2024

In hybrid and electric vehicles, the stable and precise operation of the motor significantly impacts vehicle performance. The operation of a motor depends on its electrical and mechanical parameters. This paper focuses on PMSM motor electrical parameters such as stator resistance, d-q axis inductance, and permanent magnet flux linkage. Identifying the electrical parameters of a PMSM motor is complex due to the non-linear relationship between input and output. A change in one parameter can alter the dynamic response of motor. This paper presents a comparative analysis of various PMSM electrical parameters identification techniques.

A BDT (Battery digital Twin) is a virtual representation of a vehicle's physical battery system, combining electrochemical and machine learning models to provide insights into key battery parameters like State of Charge (SOC), State of Health (SOH), Internal Resistance (IR), and Remaining Useful Life (RUL). This BDT model is calibrated using cell testing throughout its degradation process up to 80% SOH, alongside vehicle data for accurate predictions under diverse conditions. By continuously monitoring the battery under various operating scenarios, the BDT aids in effective battery management, identifying cells that degrade more quickly and the likely causes of this degradation. Current and temperature profiles offer insights into battery usage patterns. The BDT aggregates fleet-wide parameters and analyzes individual cell performance, providing critical information on SOC, SOH, IR, RUL, and voltage. Additionally, the BDT includes prognostic capabilities to alert users of potential issues like thermal runaway and other performance failures. It details faults related to current, voltage, and temperature over specified durations. Outputs are accessible through an interactive user interface, allowing users to explore battery performance over time. Validated against actual cell testing data, this cloud-based model updates in real time using field data from electric vehicles, thereby reducing battery-related issues and vehicle downtime.

Authors: Gupta Gaurav
Published: December 2024

The development and implementation of Lithium-ion (Li-ion) batteries, particularly in Automotive applications, requires substantial diagnostic and practical modelling efforts to fully understand the electrical and thermal characteristics in the batteries across various operating conditions. Electrical thermal modelling prompts the understanding of the battery electrical characteristics along with the thermal behavior beyond what is possible from experiments, and it provides a basis for exploring electrical and thermal management control strategies for batteries in electric vehicles (EVs). For replicating the electrical behavior of Li-ion batteries under varied operating situations, an equivalent circuit model (ECM) must be created. This model aids in forecasting the transient distribution of electrical and thermal properties at various operating states as well as estimating heat generation within the battery pack.

The paper focus in the following application areas:

An equivalent circuit model (ECM) will be developed to simulate the current-voltage characteristics of the battery during various discharging and drive profiles.

The electro-thermal model will be developed and calibrated by a set of characterization tests collected over a wide range of temperature, voltage, and current data.

Integration of cell to module and module to pack level through implementation along with other circuitry components like cell-cell/module-module busbars to study the voltage and temperature behavior at different scenarios.

Implementation of current limits maps and control strategies to the battery pack model to optimize the battery performance with respect to electrical and thermal behavior.

Published: December 2024

A lightning strike during raining season causes significant risks to automobiles, especially modern vehicles mostly dependent on electronic systems. Lightning can cause severe damage to electronic control unit that control the vehicle functions such as engine management, electrical circuits with sensors, braking systems, and safety features. Therefore, this research work focused for developing new electrical polymers with better conductive properties that would create a path for lightning to travel without damaging it. In-situ chemical oxidative polymerization was used to develop a new series of functional electroactive nanocomposites based on silver nanoparticles embedded poly (aniline-co-3-chloroaniline) matrix. Here we would suggest these electroactive polymers can be widely used as additive in paint manufacturing as special coatings in automobiles industry. Because of the internal chemical bonds and internal structure of these materials acts as a semiconducting nature, hence they attenuate the high energy from lightning and dissipation; therefore, it acts as a protective barrier. In order to investigate these copolymer nanocomposites, FTIR, UV-visible spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and a conventional four probe conductivity approach were all used. X-ray diffraction (

XRD) reveals the crystalline nature of copolymer. Surface morphological studies exhibit nanoneedle or nanotube or even nanorod like appearance with average particle size of 150-300 nm. During lightning, the prepared polymer composites have the capacity to absorb and transfer extremely high voltage. In order to safeguard vehicles during strong storms, these kinds novel materials ought to possess good applications in automobile industries.

Published: December 2024

Hemming is an incremental joining technique used in the automotive industry, it involves bending the flange of an outer panel over an inner panel to join two sheet metal panels. Different hemming methods are available such as Press die hemming, Table-top hemming and Robot roller hemming. Robot roller hemming is superior to press hemming and tabletop hemming because of its ability to hem complex-shaped parts and is typically used in low-volume automotive production lines. For higher production volumes, such as 120 Jobs per Hour (JPH), press hem or tabletop hem is generally preferred. However, to achieve high-volume production from roller hemming method multi station setup is used. This static multi station setup can be configured into a Turntable setup. This new method eliminates the robot load and unload time at each station in the existing setup, resulting in a 40% increase in hemming robot utilization. Therefore, this process reduces the number of robots and the required floor space while maintaining the same cycle time compared to traditional multi station hemming setups. Additionally, the need for gripper robots is eliminated, leading to a reduction of eight robots in total. This streamlined process significantly enhances efficiency and cost-effectiveness in high-volume automotive production lines. By eliminating six hem robots and two grippers and gripper robots the cost reduction is significant.

Authors: Cheni Dileep Kumar , Desai Priyanka Pradeep
Published: December 2024

With the trend of increasing technological complexity, software content and mechatronic implementation, there are increasing risks from systematic failures and random hardware failures, which is to be considered within the scope of functional safety. ISO 26262 series of standards provides guidance to mitigate these risks by providing appropriate requirements and processes. To develop a safe product with respect to above mentioned complexities, it is very critical to develop a safe system and hence a thorough and robust “Technical Safety Concept” is very important to ensure absence of unreasonable risk due to hazards caused by malfunctions of E/E systems. ISO26262-Part 4 provides guidelines for “Product development at the system level”, to design safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production road vehicles. Defining requirements at system level for each individual technology and systematically integrating them for product validation is necessary for safe system and can be achieved by Technical Safety Concept development. ISO 26262 does not prescribe a specific methodology for Technical Safety Concept development; it provides general principles for ensuring safety in automotive systems. A well-crafted Technical Safety Concept plays a pivotal role in ensuring safety and minimizing risks throughout the product development lifecycle. In an iterative process, the Technical Safety Concept is developed incorporating Technical Safety Requirements and the System architectural design. The Technical safety requirements form the basis for deriving the hardware and software safety requirements that are then used by engineering teams for developing a safe product. This paper focuses on writing an effective TSC to avoid iterative system design changes at later stages, thereby saving on re-engineering costs. It also describes the process of developing a TSC and the practical challenges encountered during projects. Our findings highlight that a well-developed TSC not only ensures safety but also significantly reduces the need for costly design changes later in the development process. By addressing practical challenges and providing a structured approach, this paper offers valuable insights for developing an improved version of TSC.

Published: December 2024

Wire Electrical Discharge Machining (WEDM) is a highly accurate machining approach that is well-known for its capability to create intricate forms in materials with high levels of hardness and intricate geometries. Invar 36, a nickel-iron alloy, is extensively utilized in industries that demand exceptional dimensional stability across a wide temperature range. The objective of this exploration is for optimizing the WEDM parameters of Invar 36 material. Additionally, a predictive model called Adaptive Neuro-Fuzzy Inference System (ANFIS) will be developed to forecast the machining performance. The study involved conducting experimental trials to analyze the influence of crucial factors in WEDM. These parameters included pulse-on time (Ton), pulse-off time (Toff), and current. The objective was to examine their influence on key performance indicators such as material removal rate (MRR), surface roughness (Ra). The methodology of Design of Experiments (DOE) enabled a systematic exploration of parameters. A predictive model using ANFIS was created to forecast machining performance by utilizing input parameters. The model was trained using empirical data to accurately capture the intricate correlations between process variables and output responses. The outcomes clearly demonstrated that the ANFIS predictive model was highly effective in accurately predicting machining performance for WEDM of Invar 36 material. The model offers valuable insights on the ideal parameter configurations to maximize machining efficiency and surface quality. This study enhances the comprehension of WEDM for Invar 36 material and provides a useful tool for optimizing the process. Manufacturers can improve machining productivity and quality in precision engineering applications by utilizing the ANFIS predictive model, thereby promoting the wider use of WEDM technology.
Calibrated Accelerated Life Testing (CALT) First Load Determination Using Systematic Step Stress Concept
Authors: Patidar Nitin , Soma Nagaraju
Published: December 2024

Calibrated Accelerated Life Testing (CALT) is a sequential and quantitative method for Accelerated Life Testing (ALT). Its design aims to optimize test efficiency by minimizing both test duration and sample size while estimating product life. In the CALT context, the focus is on testing samples under three or more distinct stresses or loads to estimate the life span/BX life, which is a crucial parameter in reliability estimation. Determining the first load in CALT typically involves exploratory testing on a limited number of specimens and relies heavily on engineering judgments such as analyzing Finite Element Analysis (FEA) outcomes, referencing test data from comparable designs and materials, and considering stiffness results etc. This often leads to challenges in accurately identifying the first load/stress. To address this issue, we propose a systematic step-stress test approach instead of exploratory testing. This approach aims to efficiently identify the first load in CALT. The step stress concept is a key part of this approach, where the product is exposed to increasing levels of stress or loads until failure is observed. This approach streamlines the determination of the first load, providing a more systematic and validated methodology. The validation process leverages existing fatigue test data from a specific program, thereby adding a robust layer of credibility to the findings. This research contributes to the field of reliability engineering by offering a practical and efficient method for first load determination in CALT, thereby enhancing the test execution process.
Development of a Method to Model Flexible Hose in FE Linear Dynamics Simulations
Authors: Ashodiya Jay Virendra , Jayachandran Janarthanan , Santhosh B
Published: December 2024

Linear dynamics simulations are performed on engine components to ensure structural integrity under dynamic loading. The finite element model of the engine assembly must be prepared accurately to avoid under or over design of the engine components. Flexible hoses are present at pipe routings and modeling them in simulations is a challenge because the stiffness of the composite is not known. The hose under study in this paper is a rubber composite with a knitted reinforcement layer. A multiscale modelling approach is presented to characterize the hose stiffness. A representative volume element geometry i.e., unit cell representation of the composite, consisting of the knitted yarn and surrounding rubber is used to establish orthotropic elastic properties at microscale, by performing finite element homogenization using the ANSYS material designer module. The homogenized properties are assigned to the macroscale hose geometry to perform modal analysis simulation in free-free and fixed-fixed condition. To validate the finite element model, experimental modal analysis is performed on the hose with the same boundary condition. Fundamental natural frequencies and mode shapes obtained from simulations and experiments are compared which shows good agreement. A predominantly automated approach to characterize the stiffness of the hose is presented and it is suggested that the hose shall be modelled using orthotropic elastic properties in linear dynamics simulations for a more accurate finite element model.
A Hybrid Model for Mitigation of Automotive Fuel Tank Slosh Noise
Authors: Titave Uttam Vasant , Zalaki Nitin , Vardhanan K Aravindha Vishnu , Naidu Sudhakara , Virmani Nishant
Published: December 2024

Slosh, a phenomenon occurring in a vehicle's tank during movement, significantly contributes to noise and vibration, often exceeding idle levels. Existing methods for evaluating NVH performance of fuel tanks primarily rely on subjective assessment, highlighting the need for a quantifiable approach to address this dynamic noise. This paper introduces a hybrid methodology to standardize the slosh phenomenon by establishing vehicle-level acceleration, braking, and driving profiles. Noise and vibration data capture, combined with defined boundary conditions, categorizes slosh noise into Impact and Roll noise, differentiated by distinct driving profiles and frequency content.

Vehicle level performance is then cascaded down to subsystem level. A dedicated test rig is designed that replicates these conditions at the subsystem level where vehicle speed and braking profiles are translated into rig-specific acceleration and deceleration profiles, enabling consistent data capture for correlation with vehicle-level results. Computational Fluid Dynamics (CFD) analysis utilizes these boundary conditions and profiles to predict forces on the fuel tank walls and identifying partial shortcomings, with forces directly correlating to noise levels.

The relationship between forces and noise supports design changes for existing fuel tanks, such as optimizing baffle designs. Several baffle designs were analyzed in CFD for their effectiveness during Impact and Roll events. The optimal design resulted in significant decrease in slosh noise and achieving acceptable cabin comfort levels. Additionally, this methodology facilitated the creation of design rules and target setting for NVH performance.

Insights gained from this study were applied to design new fuel tanks for subsequent programs, setting a new benchmark in the segment for reduced slosh noise. This not only improved occupant comfort but also reduced Direct Material Costs (DMC) by eliminating the need for additional baffles. The methodology presented in this paper offers a valuable tool for future vehicle development.

Le sésame est principalement une culture de rente, suscitant un vif intérêt chez les producteurs grâce à ses études agronomiques. Sa  valorisation joue un rôle crucial dans la lutte contre la pauvreté. En Guinée, la culture du sésame reste peu connue en raison de l’absence  d’études de caractérisation agromorphophysiologique. Cependant, sa valorisation pourrait significativement contribuer à la  réduction de la pauvreté. Cette étude visait à évaluer la performance agromorphophysiologique de trois variétés pour intensifier la  production de sésame. L’essai, mené à Faranah, portait sur les variétés S-42, Akilom et Wollega, en utilisant le dispositif de Fisher avec  trois répétitions. L’analyse de variance des données a été réalisée avec SPSS 22. La pluviométrie enregistrée durant l’essai était de  1282,16 mm. Les variétés testées ont montré de bonnes caractéristiques agromorphophysiologiques. Les cycles végétatifs étaient de 4  mois pour S-42 et Akilom, et de 5 mois pour Wollega. Les rendements en graines à l’hectare étaient de 2010 kg pour Akilom, 1762,44 kg  pour S-42, et 1855,1 kg pour Wollega. Ces résultats indiquent que la variété Akilom a été la plus performante en termes de  caractéristiques agromorphophysiologiques étudiées.

Published: December 2024

In Yaoundé (Cameroon), one deplores a lack of transparency of information between trader categories along the marketing channel of  cassava flour. This paper investigated that issue by evaluating the marketing margins among trader categories of cassava flour in the  Yaoundé urban markets. The results indicated that the yearly average net margins of different trader categories of cassava flour were  different in pairs with wholesalers earning the most (435,022 FCFA), followed in order by semi-wholesalers (333,709 FCFA) and retailers  (90,566 FCFA). The Lorenz curve coupled with Gini coefficient and Atkinson index indicated evidence of an asymmetry of information by  stratum of income for each trader category which was very high among retailers and low among wholesalers and semi-wholesalers. In  order to achieve fairness, the cassava flour traders should organise themselves into groups/cooperatives and should be accompanied by  government to promote partnership between trader groups and cooperatives and to improve their negotiation skills and marketing  information systems.
Narracje minimalne – narracje liminalne, czyli film w paradygmacie interfejsów
Authors: Gwóźdź Andrzej
Published: December 2024

TikTokization has become not only a media fact, but – like everything related to the web – also a socio-cultural one. Being on TikTok has become a symbol of cultural energy of the web, conditioned by its exposed position within both the media themselves and mobile applications.

Also within strictly film, offline (cinema and television) or streaming practices, one can now notice a trend towards telling stories in the manner inspired by the features TikTok is the epitome of: minimizing narratives in favor of small stories (micronarratives) or the aesthetics of palimpsest. Such narratives situated between different orders of visibility, in reference to Thomas Elsaesser and Malte Hagener (inspired by the concepts of Victor Turner and Arnold van Gennep), I define as liminal. It is a type of visibility in which – owing to the presence of screen messages of various electronic devices in the film diegesis (and thus also non-cinematic and non-TV dispositives: smartphones, tablets, laptops, etc.) – the filmic “window on the world” is replaced by the Surface of another screen, into which the viewer enters through subsequent visual interfaces of the film. As a result of this type of screen change, the traditional filmic “window on the world” is replaced by the figure of terminal which film represents with all its apparatus or refers its content to the world of image, thus neutralizing the image contact that is not specific to the film and making it invisible as an area of transition.

A number of visual orders, switches and apparatuses in the discussed films (Cam, Spree, Netflix series Emily in Paris) are constantly exchanged in the space of the viewer-observer drift – from overview to insight, creating an interface circuit of being in contact with screens. In this way, film creates an unstable position of the subject entangled in a network of quasi-social relations, being itself their fictitious representation.
Godless Religious Society: Uncovering the Impact of Modernism on Social Morality in the Context of Islam in Indonesia
Authors: Hardiyanto Sigit , Adela Fernanda Putra , Hutasuhut Julianto , Yarhamdhani Zhalgas , Angelia Nina
Published: December 2024

Modernism affects Islamic social morality in Indonesia, separating religious practice from realising divine values towards humans. Religious communities in Indonesia now practice rituals without deep theological value integration, creating a godless religious society that needs to be explored further. This phenomenon raises questions about religious practices without a profound concept of divinity. The method used in this research is a literature review, which involves identifying and synthesising existing literature on a particular topic. Data collection techniques are obtained using relevant academic sources, namely journals, books and articles, and the Qur'an. The data analysis technique used is qualitative descriptive analysis, which analyses and interprets the data obtained. A godless religious society reflects a shift in spiritual values towards materialism and secularism, where religion is often limited to rituals without deep appreciation. In Islam, worship is often performed as a formality, ignoring moral responsibility towards fellow human beings. As a result, religion loses its central role in shaping social ethics and becomes merely a routine empty of meaning. This dissonance between belief and practice reduces spiritual authenticity and weakens religion's potential to drive social change, as divine values are not integrated into human relations.

The Vertical and Patronage: Change of the Law Enforcement Elites in Russia’s Regions
Authors: Turovsk R. F. , Sukhova M. S. , Funk K. V.
Published: December 2024

The article analyzes the recruitment of the heads of law enforcement agencies in Russian regions. The authors collected extensive biographical dataset on all the heads of the prosecutor’s office and the Ministry of Interior in Russian regions in the post-Soviet period, which made it possible to identify the main patterns for the appointments, transfers among the regions and taking positions in the executive and legislative power bodies and the business after their retirement. The research shows that regional law enforcement agencies are characterized by strictly centralized recruitment that minimizes the ties between the heads of law enforcement services in the regions and local elites. At the same time, few regions with strong local elites and privileged relations with the federal center are able to promote their own representatives to top positions. The study also reveals the formation of clienteles associated with natives of certain areas, whose representatives occupy positions in a large number of federal subjects, as well as in the central office. The research shows that the strengthening of centralization in the law enforcement agencies in Russia is interconnected with the creation of such federal-local clienteles with regional roots and their change when federal heads of law enforcement agencies are replaced which the authors interpret as patronage.

Published: December 2024

We partially extend to hyperk\"ahler fourfolds of Kummer type the results that we have proved regarding stable rigid vector bundles on hyperk\"ahler (HK) varieties of type $K3^{[n]}$. Let $(M,h)$ be a general polarized HK fourfold of Kummer type such that $q_M(h)\equiv -6\pmod{16}$ and the divisibility of $h$ is $2$, or $q_M(h)\equiv -6\pmod{144}$ and the divisibility of $h$ is $6$. We show that there exists a unique (up to isomorphism) slope stable vector bundle $\cal F$ on $M$ such that $r({\cal F})=4$, $ c_1({\cal F})=h$, $\Delta({\cal F})=c_2(M)$. Moreover $\cal F$ is rigid. One of our motivations is the desire to describe explicitly a locally complete family of polarized HK fourfolds of Kummer type.

Cytomegalovirus reactivation (CMV-R) is a frequent complication post-allogeneic hematopoietic stem cell transplantation (allo-HSCT), associated with poor outcomes. Previous studies have demonstrated the protective effect of CMV-R against relapse after allo-HSCT for acute myeloblastic leukemia (AML). However, this impact remains unclear in acute lymphoblastic leukemia (ALL). We conducted a retrospective study on 81 patients with ALL who received allo-HSCT after myeloablative conditioning regimen from matched sibling donors between 2016 and 2022. All patients underwent weekly monitoring for CMV-R by quantitative polymerase chain reaction assay from engraftment until day +100 post allo-HSCT, and received antiviral prophylaxis with acyclovir from day +1 to 6 months after allo-HSCT. Preemptive treatment was initiated when a viremia was higher than 150 copies/mL. The median age was 20 years (range, 5–50 years). After allo-HSCT, 35% of patients developed CMV-R after a median of 39 days (range, 19–100 days). After a median follow-up of 30 months (range, 1-93 months), CMV-R was an independent factor associated with lower cumulative incidence of relapse (CIR) (OR: 0.17; 95% CI [0.03 - 0.98], p = 0.04) without survival benefit. Further studies are needed to validate the protective effect of CMV-R on ALL relapse.

The art of writing a judgment: an appraisal of the form and content of a judgment of a trial court under the Cameroon Criminal Procedure Code
Authors: Melle Akame Winslow
Published: December 2024

A judgment of a trial court in a criminal case in Cameroon is the decision of the Court that disposes of the charge or a committal order and renders the Court functus officio. This paves the way for any of the parties to file a notice of appeal to challenge the judgment or, failing that, to cause it to be executed. A judgment is, however, not only the explanation of the position of the Court: it is also a means of proving that due process was respected during a trial. In order to render it regular, a Court decision should contain adequate proof of compliance with the mandatory formalities required by law. This is because failure to mention that these formalities were accomplished leads to the presumption of their violation. The legal instruments regulating the form and contents of a judgment in a criminal case before a trial court in Cameroon are Law No 2005/007 of 27 July 2005 instituting the Criminal Procedure Code, Law No 2006/015 of 29 December 2006 on Judicial Organization, as amended and supplemented by Law No 2011/027 of 14 December 2011, and Law No 2016/7 of 12 July 2016 relating to the Cameroon Penal Code. Translation from French into English is at times faulty, inaccurate and misleading. The absence of the precise form and contents of a judgment under the Code D’Instruction Criminelle and the Criminal Procedure Ordinance has been a major setback in writing judgments and, therefore, in the absence of a unique format, recourse has to be made to the good practices of writing judgments. In this regard, the unification of laws and the inception of the Criminal Procedure Code has resolved many problems. This article reveals that a proper judgment has three parts: the introduction or heading, the evaluation of evidence or reason, and the verdict. It recommends that these should be read in open court and should have a suit number at the beginning and end with orders, a reminder to the parties of their right of appeal, an executory formula and signatures. Therefore, any judgment shy of all the parts and contents as analysed in this article will be an absolute nullity.

The Big Data analytics and Cloud Computing are the Facilitators for immense growth in healthcare systems both for patient outcomes and operational
efficiency. This would enable seamless sharing of huge volumes of healthcare data across organizations, enabling real-time decision-making and
collaborative care delivery. Healthcare providers using this infrastructure can securely store, manage, and access patient records and clinical data in
an efficient way. Big Data analytics-fueled artificial intelligence enables predictive modeling for forecasting health trends and identification of at-risk
patients for pathway optimization.AI-powered algorithms process complex data sets into actionable, pinpointed diagnostic insight with corresponding
personalized treatment recommendations. These improvements in quality come at reduced cost for care. Real-time analytics through systems connectivity
ensure timely interventions that enhance patient safety and resource utilization. It will also support the development of telemedicine, clinical research,
and health monitoring through such convergence of transformative technologies. Big Data and Cloud Computing are poised to redefine the way care is
delivered and make it more proactive, data-driven, and patient-centric as healthcare continues its journey toward digital transformation.
High Frequency RF Propagation Models in Dense 6G Networks: Challenges and Optimization
Authors:   Austin, TX, USA, Jangale Pratik
Published: December 2024

The shift to high frequency spectrum bands, such as millimeter wave (mmWave) and terahertz (THz), is critical to realizing the high data rates, ultralow
latency, and massive connectivity required for 6G networks. However, these frequencies come with unique propagation challenges, particularly in dense
urban environments. This paper explores the key propagation characteristics of high frequency RF signals and presents an overview of their modeling
approaches. Additionally, it highlights the challenges associated with shadowing, diffraction, penetration losses, and environmental factors. Various
optimization strategies are proposed, including reconfigurable intelligent surfaces (RIS), hybrid beamforming, and adaptive channel modeling, which aim
to improve signal reliability in dense network scenarios. The paper concludes by addressing future research directions, including AI-driven propagation
models and cross layer optimization for 6G networks.

Authors:   USA, Kukkuhalli Shreesha Hegde
Published: December 2024

In today’s highly competitive, data-driven environment, businesses must develop a unified understanding of customer interactions across both digital and
non-digital channels. A Customer 360 View, which incorporates touchpoints from these various sources, can significantly enhance customer relationship
management by providing a holistic view of customer behaviors, preferences, and journeys. This paper proposes a structured approach to integrating data
from these disparate touchpoints, discusses the challenges of linking data from different sources, and examines the application of advanced analytics to derive
actionable insights. Through effective data integration, real-time tracking, and machine learning techniques, this paper demonstrates how organizations can
create a seamless Customer 360 View for strategic decision-making. Towards the end of the paper, I present a case study where this approach was applied
for a midtier asset management firm to increase retail investor revenue by 20%.
