Situation-Aware Left-Turning Connected And Automated Vehicle Operation At Signalized Intersections, Sakib Mahmud Khan, Mashrur Chowdhury

Publications

One challenging aspect of the Connected and Automated Vehicle (CAV) operation in mixed traffic is the development of a situation-awareness module for CAVs. While operating on public roads, CAVs need to assess their surroundings, especially the intentions of non-CAVs. Generally, CAVs demonstrate a defensive driving behavior, and CAVs expect other non-autonomous entities on the road will follow the traffic rules or common driving behavior. However, the presence of aggressive human drivers in the surrounding environment, who may not follow traffic rules and behave abruptly, can lead to serious safety consequences. In this paper, we have addressed the CAV and non-CAV …

ENGS 89/90 Reports

Due to its lack of affordable housing and large homeless population, the city of San Francisco struggles with increasing amounts of human waste on its streets. Our system is, therefore, designed to contain and remove human fecal matter from paved surfaces. The clear dome protects the user and surrounding environment from contamination, while also allowing the user to see the cleaning process and ensure the mess is fully removed. The swiveling high-pressure jets enable the user to dislodge even dried feces efficiently and effectively. The following paper outlines the research, design, analysis, and testing involved in creating the final product.

Humeral Guide For Intraosseous Vascular Access, Alexa Lewis, Colin Minor, Josephine Kalshoven, Ellie Ng, Gabriela Lowry, Alana Tucker

ENGS 89/90 Reports

Intraosseous (IO) infusion is a procedure performed in emergency situations, in order to rapidly infuse fluid or medications into a patient’s vascular system via bone marrow in the humerus or tibia. Unfortunately, the current method for identifying the humeral insertion site (palpation) can be impossible in heavily muscled or obese patients, which may result in needle misplacement, the leading cause of complications. To overcome these difficulties, this project, sponsored by IOMETRY, Inc., focused on the development of an insertion site guide, which is compatible with current IO access equipment and allows rapid and accurate identification of the humeral insertion site.

ENGS 89/90 Reports

Following a radical prostatectomy, the main surgical treatment for prostate cancer, a majority of men will experience some level of urinary incontinence. When severe, this incontinence creates social isolation, leads to risk of infection from dried urine, and prevents men from participating in activities they love. The most common treatment in the US is a surgically placed AMS 800, produced by Boston Scientific. The AMS 800 surgery is highly invasive with a lengthy recovery time. Also, the device requires manual activation using a pump in the scrotum and erodes the urethra over time by constant compression.

3d Scanning Of Pottery Sherds For Archaeology, Zoe Yu, Jessica E. Teipel, Joseph P. Leonor, Julia A. Holgado, Zhuofan Zhang

ENGS 89/90 Reports

Archaeological digs typically last up to a few months and can produce up to 2000 sherds of pottery a day. Archaeologists cannot legally return home with their findings, so they must document them at the dig site. Current methods of documenting sherds are costly, time-consuming, and have low throughput in terms of sherds documented. Thus this team has aimed to create a scanner capable of collecting data at a rate of about one minute per sherd, allowing the user to scan 500 sherds over a 10 hour work day. Ideally, the scanner should produce 3D models of the sherds consistently …

All Faculty Articles - School of Engineering and Computer Science

An analysis was performed to determine the risk posed by wind turbine fragments on roads and buildings at the National Wind Technology Center at the National Renewable Energy Laboratory. The authors used a previously developed model of fragment trajectory and took into account the wind speed/direction distribution at the site and the probability of rotor failure. The site‐specific risk was assessed by determining the likelihood of impact and related consequences. For both the roads and buildings, the risk varied from low to routine, which was considered acceptable.

Developing A Method To Identify Horizontal Curve Segments With High Crash Occurrences Using The Haf Algorithm, Joseph Stuart Browning

Theses and Dissertations

Crashes occur every day on Utah’s roadways. Curves can be particularly dangerous as they require driver focus due to potentially unseen hazards. Often, crashes occur on curves due to poor curve geometry, a lack of warning signs, or poor surface conditions. This can create conditions in which vehicles are more prone to leave the roadway, and possibly roll over. These types of crashes are responsible for many severe injuries and a few fatalities each year, which could be prevented if these areas are identified. This highlights a need for identification of curves with high crash occurrences, particularly on a network-wide …
