Graphite: Open Source 2d Graphics Editor, Christopher H. Mendoza, Oliver A. Dolan

Computer Science and Software Engineering

Graphite is an open source 2D graphics editor aiming to provide a useful alternative to the Adobe product suite while integrating modern ideas from research and industry, including a node-based procedural approach that makes the design process fully non-destructive. Tools from the VFX and gamedev industry like Nuke, Houdini, and Substance Designer have proven the power and flexibility of node-based systems, but they are each lacking in their user experience because of the deep level of complexity that is not abstracted into simpler concepts for users (Adobe Systems, SideFX, The Foundry Visionmongers Ltd., n.d.). Graphite puts the node-based core into …

Optimization Of Flagellar Locomotion In The Low Reynolds Number Regime, Aidan M. Trodden, Aidan M. Trodden

Physics

This report investigates the computational and theoretical techniques - modeled by E. Lauga and C. Eloy - used to optimize the shape of an activated flagellum for enhanced cell motility. Cell motility is ubiquitous and has a large affect on biological systems such as marine life ecosystems, reproduction, and infection. The physical principles governing flagellar propulsion are explored using computational fluid dynamics simulations, mathematical modeling, and the sequential quadratic programming (SQP) optimization algorithm. Through iterative refinement, we can identify optimized flagellar shapes that would minimize the energetic cost dependent on a single dimensionless sperm numbers (Sp). The computation of the …

Current Source Dc-Dc Converter For Undersea Fiber Optic Sensors, Richard Anthony Esplana Kwan, John Charles Rodinec, Andrew Armstrong

Electrical Engineering

Today, there are nearly 400 cable networks spanning roughly 750,000 miles to connect our world together. With thousands of miles of cable already lying on the ocean floor, with thousands more to come, many have recognized a unique opportunity in using this cable infrastructure as an attachment point for sensors to help study and monitor the ocean. Placing sensors onto a submarine cable is not a simple task; the sensors will require power that they receive from a transmission cable, from a battery, or from the submarine cable itself. Unfortunately, the existing power feed configuration for submarine cables typically only …

Photophoretic Optical Trapping, Essa Ababseh

Electrical Engineering

Photophoretic Optical Trapping (POT) is a relatively new concept in the field of optics which has potential application in 3D display. The POT is realized by confining a particle within a very small location of the optical system, mostly around the focus. The particle, if captured by the beam, has the potential to print visible 3D images in free space. Our POT system is encapsulated by an acrylic enclosure, which also incorporates a biconvex lens as well as an adjustable focus laser module. Particles are released around the top of the lens’ focal point until the captured particle can be …

"Recloser And Circuit Breaker Controller.", Falak Patel, Ramon Jaramillo

Electrical Engineering

Electrical systems such as those used by utility companies to deliver power to residents are generally not perfect and thus can lead to many serious issues. One of which is fault current which is a current that flows when two conductors either make a short with each other or with ground. Fault current is unpredictable and extremely dangerous, as not only can it severely damage expensive equipment used by utility companies, but also risk the life and health of anybody in the vicinity. Where our project comes in is the need to monitor these electrical systems to check for faults …

Pre-Regulator Switching Converter For Photovoltaic Inverters, Lily Seymour, Stephen Alvarado

Electrical Engineering

The photovoltaic industry is constantly looking for more efficient and affordable methods to boost power generation and equipment lifetime. This project considers the design, simulation, fabrication, and testing of a DC-DC switching converter for pre-regulator photovoltaic system applications. The proposed converter is unique in that the solar array is divided up and switched between series and parallel instead of switching to charge and discharge a component for a desired duty cycle. This redesign of the conventional photovoltaic topology allows for more flexibility and control over the output voltage and current of the system, which ideally will protect the inverter from …

Reaction Wheel Based Rocket Active Spin Stabilization, Tanuj Vemuri

Electrical Engineering

Cal Poly Space Systems is the high-powered and experimental rocketry club at Cal Poly SLO. They aim to design, test, and launch fully integrated launch vehicles. In order to create efficient and reliable vehicles, stabilization systems must be implemented. One parameter that can be actively stabilized is the vehicle’s roll. The roll of the vehicle can have noticeably effects on vehicle performance, as uncontrolled roll leads to decreased system stability in flight. Un-controlled roll can also have negative impacts on the quality of onboard video, which is used for post-flight analysis and marketing.

Reaction wheels are a popular method for …

Directional Speaker, Gabriel Tramontina Ceribelli, Vincent Trevor Pierce

Electrical Engineering

Parametric Acoustic Arrays (PAA) are highly directional soundwaves whose attenuation and spread are much less affected by distance from the source as compared to traditional speakers. A well-known application for PAA is the directional speaker. Studies show that noise directly affects health and decreasing noise pollution can help improve the quality of life for millions of people. Directional speakers can revolutionize society by coupling space with sound. This project encodes audio into two RF-Pulse Width Modulated (PWM) waves to drive a transducer array. Each RF-PWM wave interferes with the other in air to generate a Single Sideband (SSB) frequency spectrum …

The EQ filtering will allow the user to attenuate or gain certain frequencies divided into the 3 standard audio bands: bass (20-300 Hz), middle (300-4000 Hz), and treble (4-20 kHz). The soft-clipping distortion stage will allow the user to move around the …

Developments In Construction Workers’ Compensation Insurance With The Use Of Biometrics, Kobe Tooch

Construction Management

Construction insurance, especially that of workers’ compensation, is vital for the protection of general contractors, but it comes at a high cost and limits their control over contract terms. Biometric devices, such as heart rate monitors and motion capture, have the potential to revolutionize the industry by reducing construction insurance premiums. Heart rate monitors can provide real-time data on workers' physical activity and health, while motion capture analyzes movements to identify unsafe movement patterns performed by workers. By monitoring workers' biometrics, construction companies can ensure their safety, prevent hazards, and implement targeted training programs. This personalized data can lead to …

Thermal Inequity And Planning Practices: Uncovering The Linkages And Creating Equitable Mitigation Strategies, Elia Rosner

City and Regional Planning

This paper examines the ways in which historical planning practices have contributed to the unequal vulnerability of marginalized communities to extreme heat, resulting in thermal inequity. Historical planning practices including discriminatory policies and uneven resource allocation, have intensified the effect of the urban heat island (UHI), leading to increased exposure to extreme heat and its associated health risk. Understanding the correlation between planning practices and the UHI effect is crucial for developing effective strategies to mitigate extreme heat impacts and improve thermal equity. By analyzing the underlying factors and consequences of planning decisions, this research aims to inform policy makers, …
