An ambitious, personal project of mine that started as an idea to store all my achievements in one place. The two criteria it needed to meet were that it must be:

     1. Easily accessible from anywhere, at any time, on anything.

     2. Be responsive across all platforms, without the loss of quality and user experience.

Consequently, I decided to buy the domain name tijvishwa.com, host it, and design the webpage for it. Initially, I opted for a template to design the portfolio. But soon, after being frustrated from the lack of quality, I chose to learn HTML, CSS, and JavaScript from scratch to create this portfolio in my vision. The result is what you see, in front of you.

Everything you can and cannot do has been meticulously hard-coded!

Admittedly, this was one of the most challenging projects I have worked on because I had no prior experience with front-end development. Having no guidance except that from the online resources, the task was particularly challenging. However, the result of persistent hard work is that this website successfully incorporates and integrates PopState Events, PushState Events, hashing, links-integration, dialogs, transitions, dark-theme/light-theme switching, download links, animations, media queries, pseudo-classes and pseudo-elements, view-all scripts, animated timeline, object comparison, callback functions, Immediately Invoked Functions Expressions (IIFE), background behavior, hamburger-menu in smaller screens, text-wraps (shape outside), and a lot more to create a seamless, cross-platform, responsive user interface. Don’t take my word for it, though… Give it a try yourself!

Collaboration between Florida Tech and Mind Technologies Inc., to calculate the force and hydrodynamic stability of a Klein side-scan sonar, using Computational Fluid Dynamics (CFD) analysis. The goal was to identify the turbulent areas and modify the design to improve the hydrodynamic stability of the Towfish.

In order to establish scientific validation to our results, we used three platforms: ANSYS Fluent, Star CCM+, and Simerics MP. The simulations ran independently, under the same working environment to establish baseline results, and to validate our findings.

The goal of Phase 1 was to establish scientific validation to our approach by obtaining the same baseline results across all three software. This validation would allow us to choose a singular software to proceed further to Phase 2: Design Improvement. Phase 1 was concluded successfully, with the results obtained cross-platform establishing scientific validation. Not only were we able to compare the results between the three software to each other, we were also able to compare filed test results to the ones obtained by Simerics MP. The following graphs discuss the same:

Phase 1 was successfully completed after the submission of our results. The data obtained through our analysis gave MIND Technologies Inc. an insight to the turbulent zones in their model. The lift and drag force data helped them quantify this visual representation.

The Department of Ocean Engineering at Florida Tech hosts scientific cruises for their seniors and graduate students every summer. The cruise sets sail from the Tampa Bay area and travels down the west coast of Florida to the Florida Keys then back up to Miami from the east coast of Florida. During this time, we deploy measuring instruments like magnetometers, side-scan sonars, underwater Remotely Operated Vehicles (ROVs) and take measurements of the seabed topography, shipwrecks, and the marine life. We also dive underwater, near the Dry Tortugas National Park, to explore the marine life and to explore the area.

Throughout the cruise I got to experience deploying the Klein 600 sonar, JW Fisher’s Proton 5 Magnetometer, and the Blue ROV2. I also got to maneuver and explore the Windjammer shipwreck by the Loggerhead Reef, at the Loggerhead Key. I learned the maritime code of conduct while being onboard, and also learned the procedure of onboard deployment and retrieval. But most of all, I loved the scenic, tranquil views of the ocean.

Follow-up project to the Nautilus, but under the Department of Ocean Engineering at Florida Tech. While the core principles and research were kept the same, this iteration underwent a complete redesign. The weight was reduced, thanks to better 3D printed material, hydrofoils were integrated to assist during lift off, and a waterjet nozzle was deigned specifically for underwater maneuvering. Our efforts were recognized at the 6th World Maritime Technology Conference, where the Flying Fish came in Second place in the Student Innovation Design Competition.

Being a follow-up to Project Nautilus, the core, preliminary research done for Nautilus carried over. Consequently, the new design incorporated the same systems architecture as the Nautilus, but also improved upon the underwater and in-water maneuverability. With the help of Dr. Yang and Dr. Wood from the Department of Ocean Engineering, the redesign was better hydrodynamically.

Crediting to the new ballast tanks which doubled as hydrofoil chambers, we were able to achieve varying bouncing during each stage of the takeoff – A, B, C, and D. Furthermore, the wing design was also tested by the team inside a wind tunnel to verify the wind-test data and behavior.

During our design stage, the team ran CFD simulations to test the viability of a good field run, in Star CCM+.

This data was then verified by the Cl and Cd performance. The redesign served as a tool to strengthen our hydrodynamics and get one step closer to a successful prototype:

Senior Design CAPSTONE project in the Aerospace Engineering, that attempts to bridge the gap between air and sea travel by targeting the development of a Multiple-Domain Vehicle (MDV) capable of long duration aerial, surface, and underwater activities. This project focuses on the development and verification of an unmanned MDV capable of operating underwater, on the sea surface and in air with transitions between mediums. These transition capabilities combined with the high aerodynamic and hydrodynamic efficiency and reliability of a folded fixed wing unmanned aerial vehicle (UAV), result in a technology that can extend operations, provide rapid response, and adds new capabilities in the ocean battlespace environment.

Being a CAPSTONE project, Project Nautilus was divided into two stages:
    1. Preliminary Design Review (PDR)
    2. Critical Design Review (CDR)

During this stage, we established the System architecture and the baseline technical design assessments.

The technical design assessments included preliminary CAD model iterations, structural Finite Element Analysis (FEA) in ANSYS, power calculations, communications designs, Aerodynamics calculations in XFLR5, and CFD simulations in STAR CCM+.

At this stage, we evaluated and verified the data gathered during the PDR stage by constructing a working prototype. This prototype was made from a mix of the fiberglass composite, 3D printed PLA, and Aluminum 6061.

During my internship at one of the plants at the Godrej & Boyce Mfg. Ltd. Co., Mumbai, India, I learned about the basics of GD&T. One of the first tasks was to learn and understand the basics of “Drawing Reading”. This referred to the reading and interpretation of engineering drawings, for parts that went inside the rocket thrusters and nozzles.
I started off by learning about symbols of straightness, circularity, parallelism, concentricity, etc., to learning about the difference between First- and Third angle views, to the types of lines -Object, Dashed, Center, Phantom, and Break. Then I learned about the different categories of dimensioning: Continuous, Baseline, Staggered, and Ordinate. During my finals days, I learned about teh various furnaces the plant utilized for heat treatments: Vacuum furnaces, Galvanizing furnaces, and Tempering furnaces. My study included learning about each furnace's specifications, pyrometry details as per ASM 2750E, it's process scope, and it's material scope.
I ended my internship by submitting a detailed report of all my learnings and understandings. This was reviewed and approved by my supervisor. Consequently, I was awarded the certificate of completion by Godrej & Boyce Mfg. Ltd. Co.
