Development of a Secure CMOS Image Sensor
No full textThis Major Qualifying Project provided integrated circuit design experience through the development of a CMOS image sensor with on-chip encryption. The imager uses an active pixel sensor with 320x240 resolution in combination with an 8-bit flash ADC and linear feedback shift register for encryption. The encrypted data is sent over USB to custom software we created to display image content and verify the EMVA1288 standard. We plan to tapeout, test, and evaluate our chip in the following year
Development of Off-road Terrain Environments Suitable for the Vehicle Rollover Testing
No full textVehicle rollover testing is crucial for vehicle design and safety. Rollover, a form of transient lateral instability, is classified as untripped (maneuver-induced) or tripped (caused by external factors like slopes, side winds, or collisions). This project mainly focuses on tripped rollover and researching the design and development of some custom offroad terrain environments that are most suitable for rollover stability testing. Specifically, different terrain and environment attributes that can trigger rollover dynamical behavior are considered including terrain materials with stochastic terramechanics attributes, terrain deformability, terrain micro and macro height profile variations, slopes and banking angles. The design process involved creating height profile maps using GIMP and Blender, then importing them into Vortex Studio, which is the main and final software. In Vortex Studio, terrains like hard soil, mud, sand, snow, and ice were assigned properties and tested with vehicle models to evaluate rollover dynamics
Franchise Value and Interest Rate Risk
No full textThis project analyzes franchise value- the present value of a firm’s future profits- and how to protect that value against changes in interest rates. The project builds upon a paper authored by William H. Panning. This project recreates Panning’s simplified insurance business model and pricing strategies as a base case. This model is then adjusted to test how pricing strategies perform under reactive consumer behavior. The aim of this project is a comprehensive analysis of how Panning’s dynamic pricing strategy handles these changes in the business model compared with a fixed pricing strategy
Observing ASSISTments Data Integrity Over Time
No full textThis IQP investigates the data collected by the ASSISTments online learning platform across different years. By training distinct Knowledge Tracing (KT) models we are able to evaluate their performance outside of their trained contexts from 2019 to the year 2024. With this, we were able to examine whether KT models have the same predictive power over time compared to their initial train year. Additionally, we helped opti- mize ASSISTments Reinforcement Learning Service (RLS) queries, reducing latency, increasing readability, and simplifying operations by switching from raw SQL to a mixture of optimized Pandas operations and SQL queries
Design and Analysis of a Low-Cost Anti-Missile Missile in Combination with a High-Powered Rocket
No full textThis report presents the design, construction, and testing of a high-powered model rocket, as well as the conceptual development of a low-cost anti-missile missile in response to the Request for Proposal (RFP) from the American Institute of Aeronautics and Astronautics (AIAA) Open Division Missile Systems Design Competition. The project was structured around two primary objectives: to build a reusable model rocket capable of reaching an altitude of 10,000 feet or less and to design a conceptual missile system that meets competition specifications. A team of students collaborated under five specialized sub-teams focused on mechanical design and recovery systems, mission operations and payload, aerodynamics, propulsion and thermal analysis, and flight dynamics and control. The model rocket incorporated commercially available motor and structural components, as well as custom-fabricated structural components, and an integrated recovery system. Simulations and analyses were conducted using industry-standard tools including MATLAB, ANSYS (Static Structural, Fluent, Dynamic), and Cantera. The anti-missile missile design emphasized cost-effective manufacturing, modular subsystems, aerodynamic efficiency, and simulated targeting and guidance capabilities. Overall, this project provided students with valuable hands-on experience in aerospace system design, emphasizing the tradeoffs and performance interdependencies critical to complex vehicle development. The results demonstrate the viability of the model rocket flight system and present a thorough conceptual design for the anti-missile missile

Optimizing Sugar Conversion: Development of "WPIPIA"
No full textIn the experimental process required to design the WPIPA recipe, our team tested which conditions achieve the highest ABV in beer brewing. The final objective was to design and produce a red, smooth, and high ABV IPA when partnering with Forty Second Brew Co. The variables that were tested were the effects of mash temperature, types of grain, yeast, and hops, as well as dry hopping on the alcohol content in beer. The results from homebrewing experimentation showed dry hopping, diastatic power in grains, and mash temperature had the greatest effect on ABV. This impacted the final product, influencing the recipe and process to create the WPIPA. The final WPIPA product appeals to a wide audience of those connected to the school, possessing a red hue, caramel and citrusy flavor, and 8.0% ABV
What does the environmental crisis tell us about science and technology?
No full textThis paper will analyze the relationship that science and technology have with the generation and handling of e-waste, along with its effects on human health and the environment. In the context of the environmental crisis, sustainable development and waste management become more important in preserving the health and stability of global ecosystems. Solid e-waste is the fastest growing waste flow on earth, serving as a pressing example of the consequences of unrestrained technological development. Expanding upon traditional definitions of e-waste, we will consider all harmful and unintended consequences of the use and production of consumer devices, including physical waste, its effect on health and the environment, and societal and mental waste resulting from online connectivity
Arm Simulator for Mechanistic Study of Blood Pressure Measurement
No full textMassachusetts General Hospital’s (MGH) blood pressure cuff offers a novel solution to the lack of a continuous, non-invasive method to measure blood pressure (BP), but demands more testing and validation before it is accepted as a non-invasive alternative to the “Gold Standard” arterial line. This paper outlines the continued development and improvement of an arm simulator, initialized by the 2024 MQP, aiming to control and record the blood pressure within a phantom arm. The team was able to achieve significant blood pressure readings utilizing a non-destructive method to support the implementation of this simulator for validation of the MGH cuff. The achieved results were within the accepted standard deviation for oscillometric blood pressure monitors of 10 mmHg, and the average systolic and diastolic blood pressure values nearly all fell within the 95% confidence intervals of their ideal human physiological ranges. A Finite-Element Analysis transient model was created to analyze the mechanics of the arm simulator
Growing National Gallery Singapore’s stART Wellbeing Program
No full textIn the burgeoning city-state of Singapore, mental health is an issue of growing importance, particularly among school-aged and college-aged youths. Adaptive solutions must be developed to support the ever-changing needs of these critical groups. Developed by National Gallery Singapore (NGS), the Strength Through Art (stART) Program is one such solution; this art-based mental wellness program aims to impart youths with the needed skills and techniques to identify & manage their emotions, laying the foundation for a healthier and more mindful consideration of the internal self. The current stART model, however, is limited in its reach and accessibility, and so, the challenge of expanding this program arises. Through research of community needs and sentiments via surveys and interviews, we collected and analyzed data from college-aged students in the USA and Singapore, and synthesized our findings in order to create recommendations for a program expansion that suits this demographic. This culminated in our recommendation of implementing an interactive, gamified, peer-led community mental health program, in order to create a more broadly inclusive & effective method of adaptive mental-health support
