The Robot-Transporter: Sex Trafficking, Autonomous Vehicles, And Criminal Liability For Manufacturers, Olivia Phillips

Dickinson Law Review (2017-Present)

Despite global condemnation, sex trafficking continues to plague our world. Even in developed countries, the problem persists. Technological advancements, like the Internet, have spurred the development of organized sex trafficking networks and have made “transactions” easier. Although law enforcement agencies have tried to adapt their investigative techniques to combat the problem, developments in technology move at a much quicker rate.

Autonomous vehicles (AVs) will present a new set of challenges for law enforcement agencies in the fight against sex trafficking. In the not-too-distant future, AVs, or “self-driving cars,” will dominate the roadways. An AV will be completely aware of the …

Maximizing Financial Benefit Of Lean Six Sigma Projects Through Optimized Selection Criteria, Colin Wasiloff

Operations Research and Engineering Management Theses and Dissertations

As evolving threats across the globe keep pace with increasing budget constraints, the US Army’s major subordinate commands and their sub-organizations are constantly challenged to do more with less. Resources such as human capital, information technology, facilities, and budgeted funding are stretched as thin as ever, while requirements to serve the Warfighter remain paramount. Each dollar of financial benefit gained through cost reduction efforts at the US Army can affect the Warfighter directly. Budgeted money saved or avoided is reprogrammed both locally and atop the hierarchy at the Department of Treasury to serve the Warfighter better.

Development Of Iowa Dot Combination Bridge Separation Barrier With Bicycle Railing, Chaz M. Ginger

Department of Engineering Mechanics: Dissertations, Theses, and Student Research

The Iowa Department of Transportation typically builds separation barriers between vehicle and pedestrian/bicycle facilities when sidewalks or trails are present on vehicular bridges. Currently, Iowa DOT employs a combination bridge rail that utilizes a concrete parapet that previously had been successfully evaluated to National Cooperative Highway Research Program (NCHRP) Report 350 Test Level 4 (TL-4) criteria for these situations. While the parapet had been successfully evaluated, the combination bridge rail system as a whole had not been evaluated to any crash test standards. Iowa DOT desired that researchers at Midwest Roadside Safety Facility (MwRSF) design and test a combination bridge …

Fan Performance Scaling With Inlet Distortions, J. J. Defoe, E. Etemadi, D. K. Hall

Mechanical, Automotive & Materials Engineering Publications

Applications such as boundary-layer-ingesting fans, and compressors in turboprop engines require continuous operation with distorted inflow. A low-speed axial fan with incompressible flow is studied in this paper. The objectives are to (1) identify the physical mechanisms which govern the fan response to inflow distortions and (2) determine how fan performance scales as the type and severity of inlet distortion varies at the design flow coefficient. A distributed source term approach to modeling the rotor and stator blade rows is used in numerical simulations in this paper. The model does not include viscous losses so that changes in diffusion factor …

Arm Mke1xf Mcu Replatform, Nathan Hong, Derek Lung, Japsimran Singh, Bevin Tang

Computer Engineering

After Cal Poly Racing’s electrical team began to hit the technical limits of the ADC and other I/O features of the current 8-bit Atmel AT90 microcontroller unit, it became clear that an upgrade was due. This replatforming project takes the functionalities of the old, 8-bit architecture, and aims to provide a 32-bit version using the ARM MKE1xF MCU. With the idea of having a working PCB as a stretch goal, the scope of the library development was limited to enable base functionality. Thus, the only libraries developed were for the Timer, ADC, SPI, UART, and CAN. Additionally, this document discusses …

Cure History Dependent Viscoelastic Modeling Of Adhesively Bonded Joints Using Mat_277 In Ls-Dyna®, Akshat Agha, Fadi Abu-Farha, Rakan Alturk, Tim Welters, Georges Romanos

Publications

The effects of Coefficient of Thermal Expansion (CTE) mismatch in multi-material adhesive joints, induced during the manufacturing process, are expected to hinder the peak performance of the adhesive in the service life of the vehicle. With a goal to estimate these effects, this paper attempts to model the curing phenomenon of an adhesive and predict its mechanical properties using MAT_277 material model available in LS-DYNA, which serves as a good starting point towards modeling the cure history dependent viscoelastic behavior of adhesives. The adhesive is used to join two substrates of dissimilar metals and tested to capture the relative displacement …

Vehicle Pseudonym Association Attack Model, Pierson Yieh

Master's Theses

With recent advances in technology, Vehicular Ad-hoc Networks (VANETs) have grown in application. One of these areas of application is Vehicle Safety Communication (VSC) technology. VSC technology allows for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications that enhance vehicle safety and driving experience. However, these newly developing technologies bring with them a concern for the vehicular privacy of drivers. Vehicles already employ the use of pseudonyms, unique identifiers used with signal messages for a limited period of time, to prevent long term tracking. But can attackers still attack vehicular privacy even when vehicles employ a pseudonym change strategy? The major contribution …

Diesel Particulate Generation, Matthew Ferdenzi

Honors Theses

The goal of this project is to design a diesel particulate generator to test aerogels as diesel particulate filters. Diesel particulate generators are machines that generate diesel particulate matter, or diesel soot. Diesel particulate filters have been recently put into the market to help many car companies meet the ever-changing diesel emission regulations set by the EPA and other international agencies. The main goal of the filter is to block soot from exiting to the environment. Once the filter is full, the soot is oxidized and released. The problem with these filters is that they are large, costly, detrimental to …
