Improving Data Quality For A Dairy Pollutant Emissions Study, Ian K. Hahus, Albert J. Heber
Improving Data Quality For A Dairy Pollutant Emissions Study, Ian K. Hahus, Albert J. Heber
The Summer Undergraduate Research Fellowship (SURF) Symposium
The National Air Emissions Monitoring Study (NAEMS) was sanctioned by the EPA to determine the characteristics of airborne pollutant emissions from confined broiler, egg, pork, and dairy housing. Fifteen representative monitoring sites were selected around the U.S., at which influent and effluent pollutant concentrations were measured in conjunction with airflow and climatic data. Due to the monumental nature of this study and the potential ramifications of its findings, it is of vital importance that the data collected by the researchers and utilized by the EPA be as complete and accurate as possible. To improve the validity of the data collected …
Detection Of Foodborne Pathogens By Micro-Filtration Using A Continuous Cell Concentrator Device, Klaire E. Jeffries, Eduardo Ximenes, Michael R. Ladisch
Detection Of Foodborne Pathogens By Micro-Filtration Using A Continuous Cell Concentrator Device, Klaire E. Jeffries, Eduardo Ximenes, Michael R. Ladisch
The Summer Undergraduate Research Fellowship (SURF) Symposium
Protecting consumers from foodborne illness is an important health concern facing the food industry today. An important deficiency exposed by foodborne illness is the inability to track contaminated food back to the source in a timely manner. Although there are established methods that detect bacterial pathogen contamination, they are limited in distinguishing viable bacteria reliably and quickly. Currently, food pathogen testing requires lengthy culture steps, which many times are delayed even longer due to the lack of in-house testing labs. Typically, two to three days elapses between when the food is sampled and the test results are available. This study …
Computer Simulation Study Of Slipper Lubrication In Hydraulic Machines, Jordyn B. Miller, Monika Ivantysynova
Computer Simulation Study Of Slipper Lubrication In Hydraulic Machines, Jordyn B. Miller, Monika Ivantysynova
The Summer Undergraduate Research Fellowship (SURF) Symposium
Hydraulic pumps and motors are vital components used in many applications today. Specifically, the axial piston pump is important because it is reliable, relatively compact, and has a high horsepower-to-weight ratio. These features make this type of pump very advantageous in hydraulic systems. Maintaining proper lubrication between surfaces in an axial pump, such as the slipper and swashplate, is imperative in order to have smooth operation of the system and prevent metal-to-metal contact. The aim of this research is to find the optimal slipper design and fluid film thickness to simultaneously maintain a balanced pressure and decrease power loss in …
Driftwatch Pollinator Mapping Application, Shreyas G. Sundararaman, Larry Theller, Bernard Engel
Driftwatch Pollinator Mapping Application, Shreyas G. Sundararaman, Larry Theller, Bernard Engel
The Summer Undergraduate Research Fellowship (SURF) Symposium
Over 65% percent of food consumed in the United States is pollinated by bees. Unfortunately, due to poor farming practices, pesticides are sprayed in bee sensitive areas unknowingly and as a result, the bee population is dwindling at an alarming rate. With lesser bees to pollinate crops, produce is compromised on a very large scale and this could have disastrous impacts on the nation's needs for food. Apiarists and beehive owners face the major responsibility of ensuring that their hives aren't affected by dangerous insecticides and pesticides from the farming areas that they might visit during their crop pollination cycles …
Design Of A Novel Actuation System For Variable Displacement Gear Machine, Mark W. Mahuren, Andrea Vacca
Design Of A Novel Actuation System For Variable Displacement Gear Machine, Mark W. Mahuren, Andrea Vacca
The Summer Undergraduate Research Fellowship (SURF) Symposium
External spur gear pumps are exceedingly useful components in common hydraulic systems. The main issue with external gear pumps is that all current models are limited to only fixed-displacement. This means that for every revolution of the gears inside the pump, a set amount of fluid will always be displaced. Consequently, external gear pumps are limited in their use because they can only operate at full throttle causing inefficiencies when reduced displacement is needed. The successful procurement of a variable displacement gear pump will allow a more efficient use of hydraulic systems, such as in the displacement controlled systems used …

Crane Shaking Platform Design, Bixing Yan, Andrea Vacca
The Summer Undergraduate Research Fellowship (SURF) Symposium
Most of the control methodology of Mobile hydraulic crane is not as energy efficient as people think or want, and the desire to innovate novel, energy-efficient control strategy is the target of most hydraulic experts. To develop or test the control method under real road and off-road conditions, a platform that could simulate the movement and vibration of the crane truck is desired. To design and build the multi-operation platform, a design process includes brain storming, design selection, FEA (Fundamental Element Analysis), mechanical sizing, hydraulic sizing and Bill of Material is required and preferred. After going through all the steps …
Optimization Of Oil Extraction Of Soy Flour Using Mini Extrusion Technology, Alisha Chess, Martin Okos
Optimization Of Oil Extraction Of Soy Flour Using Mini Extrusion Technology, Alisha Chess, Martin Okos
The Summer Undergraduate Research Fellowship (SURF) Symposium
Mini extrusion technology is a relatively new technology that offers fast timing and processing of food products. This technology paired with the advantageous properties and growing demand for soybeans can lead to a larger span of uses for the extruder that have not yet been explored, including NASA space missions and incorporation of soybeans into developing countries. During past research on parameters of operation, it was discovered that a significant amount of oil was being separated from the soy meal at the die of the mini extruder. Maximum removal of this oil allows use of the soy meal and soy …

Estimation Of Two-Stage Ditch Excavation Volume Using Lidar Data Full Paper, Kirsten E. Paff, Jane Frankenberger, Naime Celik
The Summer Undergraduate Research Fellowship (SURF) Symposium
Drainage ditches are a major pathway for sediment, nutrients, and pesticides to enter stream systems, which threaten environmental and human health. Unlike trapezoidal ditches, two-stage ditches have a vegetated bench that acts as a floodplain, which helps to prevent erosion and to increase the processing of nutrients to improve water quality. Converting a trapezoidal ditch to a two-stage ditch is expensive, due to the large volumes of soil that need to be excavated. Since ditch geometries vary significantly and surveying each potential site by hand would be time consuming and expensive, a tool based upon online Light Detection and Ranging …
