- Description:
- Traffic congestion on the freeways is one of the worst issues in California. During peak hours, traffic can slow down to a stop-and-go crawl. A significant cause of this behavior is driving habits: human beings have a tendency to drive closer as they slow down, which makes merging difficult and exacerbates the slowness. The Tail Gator app uses machine vision to, when placed on the dashboard of a normal car, collect and relay information to the driver in a hands-free manner regarding the vehicle in front of them. It would tell the driver the distance and relative speed of the car in front of them, which the driver can then use to build good, anti-congestion driving habits and stop tailgating in traffic. The technology behind this has further applications: it could be used to recommend to drivers optimal speed and acceleration based on the traffic situation, which would also be useful in guiding the behaviors of self driving cars to better the road for everyone.

- Description:
- The Force Concept Inventory (FCI) is an important diagnostic tool widely utilized within the PER (Physics Education Research) community. While students' performance on the FCI has been extensively studied, relatively less work was done in primarily undergraduate institutions (PUI) and minority-serving institutions. As part of an effort to provide evidence for the reproducibility of educational studies for a variety of student body as well exploring possible gender or racial gaps in student's performance, data was collected over a year-long period for a number of introductory physics courses at Cal Poly Pomona (both a PUI and Hispanic serving institution) to understand factors that affect students' performance on the FCI. In this work, we discuss background variables that predict students' FCI scores at the end of the term. This baseline measure can be used for any future studies conducted at our institution to evaluate the effectiveness of any pedagogical reforms. We will also explore possible gender or racial gaps for our student body.

- Description:
- In the present study, we plan to examine the neural correlates of the conscious recollection of long-term memories (LTM). This process is defined as the retrieval of qualitative or associative information during recognition, and a wealth of studies have shown it is dissociable from "familiarity", which is a strength-based type of recognition. However, fewer studies have focused on whether the cognitive and/or neural basis of recollection differs as a function of the type of association that is retrieved. We take up this question in the present study and hypothesize that the electroencephalographic (EEG) activity and event-related potentials (ERPs) associated with recollection following item-feature vs. item-item associative encoding differs. Following the performance of two mental imagery encoding tasks (separation imagery and interactive imagery), designed to promote dissociable levels of recollection of item-feature vs. item-item, respectively, yet comparable levels of item recollection, we will record EEG while participants perform a recognition memory task sensitive to the contribution of recollection or familiarity. This will permit us to investigate whether the specific ERP associated with recollection, the "P600 old/new effect", differs as a function of encoded association. We will examine whether overall oscillatory activity differs as well. of the brain that occurs during item recollection. Overall, we believe that our results will help inform neurocognitive models of recognition LTM.

- Description:
- The integration of unmanned aerial vehicles (UAVs) into the national airspace system presents itself with a myriad of technical problems. One of the key requirements for this integration is the human equivalent level of safety, which requires the ability to detect and avoid other aircraft/obstacles in their flight path so that the UAVs complete their mission without any loss or damage to other aircraft or property. This presentation talks about the use of ADS-B (Automatic Dependent Surveillance- Broadcast) transponders for detection of collision of other similarly equipped aircraft/UAVs. ADS-B transponders can receive and broadcast global position and velocities among other pertinent information in a 100-nautical mile radius. This research used Ping-2020 ADS-B transponders for the collision detection. The collision detection and avoidance is first tested in software-in-the-loop simulation, which also uses the flight controller, Ardupilot, and ADS-B transponders in the loop. MAVproxoy, a UAV ground station software package, is used to communicate between in the autopilot and simulation environment via MAVLink. FlightGear flight simulator is used to visualize the motion of the UAVs. The research uses two fixed-wing aircraft equipped with Pixhawk autopilots, which allow autonomous waypoint navigation. The collision avoidance algorithms use a three-step system of detect, predict, and avoid. The algorithm calculates and sends the waypoints for collision avoidance to the autopilot. Using the kinematic equations, the UAV velocities can be calculated from the information received from GPS sensors, and future positions can be predicted. The collision avoidance algorithm is tested using the incoming information from real-time aircraft.

- Description:
- One of the issues that the world is facing is that we are running out of the fossil energy resources, and the use of renewable ones is currently limited. Recently, researchers have put lots of efforts to find a way to use biomass as one of the possible renewable sources. They realized that it is possible to convert this biomass material into organic compounds that are close to the characteristics of petrochemicals. One of the reactions that help in this process is the catalytic deoxydehydration (DODH), which is a reaction that removes two adjacent hydroxyl groups (-OH) from vicinal diols to produce alkenes. The DODH reaction requires a catalyst and a reducing agent that help in completing the reaction. According to the article " Deoxydehydration (DODH) of Biomass-Derived Molecules", the first catalytic deoxydehydration was demonstrated by Andrews and Cook using PPh3 as the reducing agent and Cp*ReO3 as the catalyst (1). Subsequently, researchers started synthesizing catalysts with different metals (such as rhenium, ruthenium, vanadium, or molybdenum) adding various reductants such as phosphines, sulfite, alcohols while changing the other parameters such as temperature and reaction time. In this research paper, molybdenum-based catalysts for DODH are discussed.

- Description:
- We have developed molecular techniques to identify classes of cyanobacteria for early toxin threat detection and control before the growth becomes toxic. This screening is part of a larger sustainability project focused on converting dairy cow manure effluent into a fast-growing, algae-based, safe animal feed crop. The algae are produced in paddle-wheeled model ponds on the dairy farm which could become contaminated by toxic cyanobacteria. To ensure the integrity of our analysis, multiple species of pure cyanobacteria cultures were grown and their DNA purified. The 16S rRNA and rpoC1 gene sequences were targeted for their universal detection of cyanobacteria using PCR. To distinguish cyanobacteria species that have the potential to produce toxins, four gene clusters in the toxin synthesis pathways were targeted: mcy (microcystin), nda (nodularin), cyr (cylindrospermopsin), and ana (anatoxin-a). PCR-amplified fragments were separated using agarose gel electrophoresis and sequenced. 16S rRNA/rpoC1 PCR assays allowed for positive identification of quality control strains (QC) and exhibited the sensitivity and specificity to discriminate against multiple genera of non-cyanobacteria strains. Within our QC strains we have identified strains that indicate potential to produce microcystins, and anatoxin-a. Toxin production was quantitated using Abraxis/Beacon ELISA kits. Our future goal is quantitation of the toxin genes with qPCR. This protocol will routinely detect and identify the presence of cyanobacteria species that could produce toxins in algae production ponds and allow for their control in algae-based livestock feed operations.

- Description:
- There are an estimated 100,000 cases of torn Anterior Cruciate Ligaments (ACL) in the United States each year. Although autografts and allografts are approved treatments, they are expensive, labor intensive, cause donor site morbidity, and require a lengthy patient recovery process. Despite decellularization treatments, DNA left in allografts can increase the risk of disease transmission and immunogenic response. Synthetic implants eliminate the harvesting procedure and have great biocompatibility. Understanding the time dependent properties of a synthetic material that closely matches those of native ligaments is imperative for ACL reconstruction innovation. PLG 10-90 (L-lactide -co-glycolide) monofilament is an absorbable biopolymer and strong candidate for ACL reconstruction. The biopolymer sufficiently matches average native ACL tensile strength and percent elongation to fracture. Additionally, the dissolution time of PLG 10-90 is approximately the same as ACL growth time. This inversely proportional relationship offers the potential of scaffold reconstruction procedures. This research will determine a set of evolutionary equations which predicts failure under a variety of conditions. Specimens are stored under an assortment of loads at in-vivo conditions. A specimen is then subjected to one of several tensile tests, including a jump test, to determine the properties at different time points. These tests illustrate the time dependent properties in terms of rate of dissolution and strain rate. This data will show a relationship between the strength of PLG 10-90 and its dissolution which is required to build a constitutive model and determine the viability for ACL reconstruction.

- Description:
- Measuring naturally occurring radioactive material is of great interest in monitoring soil and rocks, which are important in assessing health risks to a population and serves as a reference in documenting changes to environmental radioactivity. These measurement practices are taught to upper division physics students in laboratory. Physics students study gamma spectroscopy and isotopes that produce decays using Ge detectors, whose operation require liquid nitrogen cooling and is therefore costly. The use of an affordable and more portable detector, the NaI detector, without sacrificing the precision needed in upper division physics courses is being studied. Known decay products from sources containing 40-K, 238-U, and 232-Th were used for calibration. The gamma energy peaks that were measured include: 1440 keV for K-40, 1764 keV for the Uranium-238, and 2614 keV for the Thorium-232 series. A secular equilibrium was used to assume that the activity of each isotope within their decay series were the same. The results from the calibration sources indicate using the NaI detector for monitoring soil samples is efficient, cost effective and promising.

- Description:
- The purpose of this research is to make Cal Poly Pomona a more water sustainable community by looking at the following areas: water reuse and reclamation, stormwater management, and low impact developments. The amount of stormwater for the campus is 2035.96 acre-foot per year which is a commodity and is being lost every year. Buildings and parking lots are not environmental friendlies because they collect water with waste which could be improved on. To begin, the safe clean water program, a program that provides fund for projects in L.A. County, was analyzed for Cal Poly Pomona to become a potential project funded by the Measure W tax. Moreover, low-impact developments and native plants are examined in preparation for the survey of the campus. To organize the survey, a map of the campus is divided into four sections and the GIS data was utilize to obtain a better idea of the geography. Each section was inspected and discussed. Discussions focus on improving the reuse of stormwater and, implementing native plants and low-impact developments. The results of the survey showed that Cal Poly Pomona has a number of nonnative plants that could be replaced or removed, current drainage systems that need to be properly maintained, construction of low-impact developments such as rain gardens, bioretention, and dispersion and establishment of a new stormwater collection system. Overall, the survey shows that Cal Poly Pomona could benefit from Measure W by receiving funds and will benefit from our proposed scheme.

- Description:
- Insemination must occur near ovulation, however in swine there is no practical way to determine when ovulation occurs. It is common practice to artificially inseminate (AI) each sow repeatedly over the course of an estrus period in an attempt to maintain fertility numbers. OvuGel® (JBS United, Sheridan, IN) is a product (intravaginal administered GnRH agonist triptorelin) that has been shown to synchronize ovulation in sows, allowing for a single fixed-time insemination to be used. Despite the promising results from initial studies using OvuGel, triptorelin uptake rates may be affected by a number of factors. Combining Ovugel with isotonic sodium chloride has the potential to increase uptake and the effectiveness of the compound. Identifying the optimal quantity of sodium chloride to maximize triptorelin uptake, increasing ovulation precision and maximizing farrowing rates all would provide a significant economic benefit to the swine industry.
