Accurately forecasting potential customers, reducing resource waste, and improving efficiency may all be necessary for telemarketing to be productive. To find clients, we use machine learning models such as Random Forest, XGBoost, AdaBoost, and Gradient Boosting. F1 score, recall, accuracy, and precision are used to assess these algorithms. To address class imbalance in telemarketing datasets, oversampling techniques like SMOTE, ADASYN, and Borderline SMOTE generate synthetic data for underrepresented classes. Model performance is improved by MinMax scaling data normalization and Mutual Information feature selection. Training and testing are conducted using telemarketing data from the Portuguese Bank Marketing Data Set. Modifying the XGBoost hyperparameters raises the model's accuracy to more than 98% for both the top 10 features and the complete set. To promote user involvement, the system has a real-time prediction interface built on Flask. Ensemble-based online machine learning, a successful telemarketing optimization technique, enables models to adjust to shifting customer preferences.

Work-life balance has become an important organizational strategy that enhances the psychological wellbeing, productivity and motivation of employes. Organizations that successfully encourage work-life balance are likely to have motivated employes which improves performance at an individual and organizational level. The present study is an attempt to investigate the work life balance and employe motivation of Nabil Bank Limited Kathmandu, Nepal. Primary data was obtained from 45 employes by means of structured, closed-ended questionnaires. The study employed descriptive statistics and correlation analysis to determine the relationship between variables. Data entry, tabulation and initial analysis were done using Microsoft Excel while SPSS software was used for data processing and analysis. The findings indicate that work-life balance is affected by many factors like flexible work environment, work load, supervisor help and family friendly regulations. Also, the results show that there is a positive relation between work-life balance and employe motivation. This means that those employes who have a good work-life balance are more motivated and dedicated to their careers. The study concludes that work-life balance initiatives are most effective when accompanied by a positive corporate culture and a supportive management style. Both factors enhance employe engagement and increase overall organizational effectiveness.

The structural framework of automotive vehicles has undergone significant evolution, transitioning from heavy, rigid steel constructions to optimized lightweight designs driven by advancements in computational engineering. In particular, three-wheeler vehicles, widely used for urban mobility, present unique challenges due to their asymmetric geometry and uneven load distribution. Historically, conventional chassis systems have relied on welded steel ladder frames, which, although robust, suffer from excessive weight, poor vibration characteristics, and inefficient stress distribution under dynamic loading conditions. These limitations often lead to increased fuel consumption, structural deformation, and reduced operational lifespan. The primary problem addressed in this study is the lack of an optimized chassis design that simultaneously ensures strength, stability, and reduced mass for three-wheeler configurations. Traditional design approaches are largely empirical and fail to adequately predict structural behaviour under real-world loading scenarios. Hence, there is a critical need for a simulation-driven methodology to enhance design reliability and performance. This work proposes an integrated computational framework combining Computer-Aided Design (CAD) and Finite Element Analysis (FEA) to develop and evaluate a ladder-type chassis structure. The model is created using SolidWorks and analysed in ANSYS under various loading and boundary conditions. Multiple materials, including Gray Cast Iron, Cast Iron, and Titanium Alloy, are investigated to determine optimal performance characteristics. The proposed system enables precise identification of stress concentration zones, deformation patterns, and vibration modes. The results demonstrate that material selection and structural optimization significantly improve the strength-to-weight ratio and dynamic stability. This study contributes to the development of safer, more efficient, and lightweight three-wheeler chassis designs, supporting advancements in sustainable and cost-effective urban transportation systems.

The performance and durability of a 4-stroke Internal Combustion (IC) engine are strongly influenced by the thermal behavior and material selection of its key components. Traditional design approaches relying on empirical calculations and experimental methods are often time-consuming and limited in capturing complex thermal interactions. In this study, a computational approach is adopted to evaluate thermal performance efficiently. A detailed 3D model of the engine assembly, including the piston, connecting rod, and crankshaft, was developed using SOLIDWORKS and analyzed in ANSYS Workbench under steady-state thermal conditions. Three materials Gray Cast Iron, Aluminium Alloy, and Stainless Steel were assessed based on temperature distribution and heat flux characteristics. The results show that Aluminium Alloy, despite its high thermal conductivity and low weight, exhibits higher thermal expansion, which may compromise structural stability. Stainless Steel demonstrates superior thermal stability, reduced deformation, and better resistance to high-temperature stresses, making it the most suitable material for thermally critical components. Gray Cast Iron provides moderate performance but is less effective under extreme conditions. Overall, this study highlights the effectiveness of Computer-Aided Design (CAD) and Finite Element Analysis (FEA) based analysis in optimizing material selection, reducing development time, and improving the reliability and performance of IC engines.

A V12 engine is a multi-cylinder internal combustion configuration comprising twelve cylinders arranged in two banks, typically inclined at 60° to form a V-shaped geometry. This configuration ensures uniform firing intervals, inherent dynamic balance, and superior smoothness compared to lower-cylinder engines, making it highly suitable for luxury, high-performance, and heavyduty applications. The present work focuses on the comprehensive digital development and evaluation of a V12 engine assembly using SOLIDWORKS. The complete engine model incorporates critical components including pistons, connecting rods, crankshaft, cylinder head, camshaft, valves, crankcase, lubrication system, and spark plugs, all designed with precise geometrical specifications. Following the modelling phase, advanced simulation tools are employed to investigate the thermal behaviour of key components under a high thermal load of 800 K. Thermal analysis is specifically conducted on the piston, crankshaft, camshaft, and valves to evaluate temperature distribution and heat dissipation characteristics under operating conditions. The simulation results provide detailed insights into thermal gradients and critical stress regions, enabling comparative assessment of component performance. Based on these findings, suitable materials are identified and selected to enhance thermal stability, durability, and overall engine efficiency. This integrated CAD-CAE approach demonstrates the effectiveness of simulation-driven design in optimizing engine components, reducing development time, and improving performance reliability in complex multi-cylinder engine system.
