Vehicle Dynamics
This project involved a comprehensive study of various aspects of vehicle dynamics, including forward dynamics, steering dynamics, planar and roll dynamics, and vehicle vibrations. It aimed to understand how vehicles respond under different driving conditions and maneuvers. I have used MATLAB/Octave for mathematical modeling and simulation to evaluate the vehicle's dynamic behavior. This included calculating reaction and brake forces and understanding the vehicle's response to different driving scenarios, such as acceleration on inclined roads and lane-change maneuvers.

Dynamics of Human Movement
Dynamics of Human Movement
Two fundamental experiments in biomechanics were conducted to record motion and ground reaction forces. In the Motion Analysis project, we used a video-based system with Cortex64 software and passive markers to study human gait while walking and running. By analyzing the 2D sagittal plane, we calculated different body segments' angles, velocities, and accelerations. Key findings included maximum speeds of the lateral malleolus occurring at 80% of the gait cycle during walking and 70% during running. This research provides valuable insights into gait mechanics, aiding in designing effective rehabilitation programs and performance enhancement strategies.

The GRF Analysis project studied the forces exerted during walking and running using Optima 464508-2000 Force Plates. We measured vertical, anterior-posterior, and medial-lateral forces for the studied subject. During walking, the maximum vertical braking force was 104.6% of body weight, while the maximum vertical thrust force was 112.05%. For running, these values were 144.36% and 195.36%, respectively. This analysis helps in understanding the kinetics of human gait, contributing to improved training programs and injury prevention.

Finite Element Methods (FEM)
These projects are part of my graduate-level CAD-Finite Element Method course, in which I analyzed finite element problems related to natural frequency, beam deflections, and heat transfer. I have used the Galerkin method to obtain the FEM solution of the partial differential equations and then compared it with the exact solution. MATLAB/OCtave was used to perform the numerical calculations, while ABAQUS was used for the simulation. The list of problems solved using finite element approximation are as follows:

Active Heating System Using TRNSYS
Active Heating System Using TRNSYS
This research investigates the thermal performance and energy consumption of buildings in Nepal, where current construction codes overlook thermal behavior, leading to uncomfortable indoor climates. Focusing on the Thakle Integrated Settle, we utilized field data and TRNSYS simulations to analyze heating and cooling demands based on building orientation. The study found that heating demand accounts for 37% of the year, while cooling and comfort conditions comprise 32% and 31%, respectively. We incorporated a radiant floor heating system and a domestic hot water system to improve thermal comfort. Our findings indicate that solar-powered heating solutions can significantly enhance energy efficiency and comfort in Nepalese buildings.

Compressed Air Energy Storage
As a practical approach to implementing power load shifting, foster the accommodation of renewable energy, such as wind and solar generation. Energy storage techniques play an important role in facing the great challenge of maintaining power network stability and reliability. Compressed Air Energy Storage (CAES) is a promising energy storage technology due to its cleanness, high capacity, low cost, long storage duration, and long service life. However, the cost and scale are similar to that of a pumped hydro storage system (PHS) and other storage systems. The project's primary objective was to develop the laboratory setup of CAES to analyze the efficiency of different types of CAES and other various parameters and propose suggestions for future technology development.
