Jeff HawksEarly Stage Development of a Medical Device for Non-invasive Measurement of Intracranial Pressure
Jeff A. Hawks, Mechanical & Materials Engineering, and  Greg R. Bashford, Biological Systems Engineering, University of Nebraska – Lincoln, NE

This research will work to develop a prototype medical device that can non-invasively measure intracranial pressure (ICP).  Astronauts currently onboard the ISS have been trained to perform ocular ultrasounds by NASA space medicine instructors in order to obtain images of the optic nerve sheath during spaceflight.  Studies have shown that the diameter of the optic nerve sheath can be used to detect increased intracranial pressure.  Ultrasound equipment is already available on the ISS.  Astronauts also use hand-held tonometry to measure intraocular pressure (IOP), but many recent studies have shown no distinct correlation between IOP and ICP. The proposed objective is to develop a prototype device integrated with pressure sensors and actuators that can be used to non-invasively measure intracranial pressure. One objective of the proposed work is using a one-dimensional, non-imaging Doppler ultrasound transducer to detect Greg Bashfordblood flow within the ophthalmic artery.  The feasibility of this can be experimentally demonstrated within the laboratory.  Eventually, the proposed prototype would be developed into a stand-alone handheld device.  Since the goal of the device is to measure intracranial pressure, an imaging ultrasound probe (linear array) would not be necessary.  This would eliminate the need for large computer equipment needed to view the images.  Producing an imaging array is possible, but is not an objective under the funding of this proposal. A mechanical device equipped with actuators and pressure transducers will be used to apply pressure to a eye during ultrasonography.  The user will simply hold the device in place while a telescoping housing will apply pressure to the eye.  Pressure transducers will measure the absolute pressure applied to the eye.  Once again, laboratory experiments will be used to demonstrate the feasibility of this task using appropriate biomaterials to simulate the tissue mechanics of the eye. Once both tasks have been demonstrated independently in the laboratory setting, they will be integrated into a single prototype device.  This device will operate similarly to the methods used to measure mean arterial pressure.  Pressure will be applied to eye until blood flow is stopped or decreases.  Once this is detected using the Doppler ultrasound transducer, the applied pressure will be measured using the pressure transducer.  This pressure reading can be used to estimate intracranial pressure near the ophthalmic artery.  Laboratory models of artificial tissue will be used to demonstrate the feasibility of the proposed device.  Ocular elasticity can vary among individuals.  Therefore, it is important to test the efficacy of the proposed device over a range of different tissue elasticity.  The proposed device would be automated so that a user would measure intracranial pressure at the push of a button.

Travel Grant to Attend the 5th Werhner von Braun Memorial Symposium
Jeff A. Hawks, Mechanical & Materials Engineering, University of Nebraska – Lincoln, NE

The purpose of this travel grant is to attend the 5th Werhner von Braun Memorial Symposium in Huntsville, AL.  This travel will help build upon the relationship and visibility among program directors at NASA.  Collaborative projects between engineers at UNL and medical researchers at UNMC have both a Nebraska Space Grant and NSBRI Step 1 Proposal under review.  Collaborators at NASA include Victor Hurst, who is a Senior Scientist and Space Medicine Instructor with Wyle’s Integrated Science and Engineering Group, Richard Cole (NASA and Wyle Flight Surgeon), and more recently Jimmy Wu (Deputy Project Manager for Advanced Projects with Wyle’s Science, Technology and Engineering Group).  The purpose of attending this conference is to discuss and listen to NASA program directors who will speak about the current needs and interests among their various directorates.  NASA is looking for research on techniques for non-invasive measurement of intracranial pressure during spaceflight so that long-duration space missions are safe for astronauts during human exploration missions.  Speakers of interest include Robert Lightfoot (acting NASA Associate Administrator) and Mason Peck (NASA Chief Technologist).  One panel topic is “NASA Human Space Exploration Plans and Update,” which is moderated by Dan Dumbacher (Deputy Associate Administrator for Exploration Systems Development at NASA HQ).  Another relevant panel is entitled “Robotic and Human Exploration” moderated by Jim Garvin (Chief Scientist, NASA GSFC).  Panelists for that panel include Victoria Friedenson (Manager, Joint Robotic Precursor Activities, Human Exploration and Operations Directorate, NASA HQ), Fuk Li (Director, Mars Exploration Directorate, Mars Exploration Program Manager, JPL), and Dan Schumacher (Manager, Science and Technology Office, NASA MSFC).  Attending this conference will benefit the aims of future funding proposals to NASA by listening to various program managers discuss NASA’s relevant needs.  Many of these managers serve as review panelists for proposals or are in direct contact with review panelists.

 

Benjamin TerryNoninvasive, Ambulatory, Long-term, Deep Gastrointestinal Biosensor and Implanter
Benjamin S. Terry, Mechanical and Materials Engineering, University of Nebraska – Lincoln, NE

Developing biosensor systems has long been a high priority for NASA because they are essential for monitoring health and safety of the astronaut; however, continuous, reliable, long-term, ambulatory, biostatistical monitoring that does not interfere with the mission’s sometimes physically rigorous duties is still elusive. We are therefore creating a new critical biosensing technology that will make NASA’s crewed space exploration missions more capable. The proposed work will lay the foundation for a larger, comprehensive study, the aim of which is to create a new biosensing system that is intuitive and transparent to the patient, yet robust and reliable. The new biostatistical sensing system is designed to facilitate monitoring the health of astronauts on long-term missions where terrestrial medical facilities and personnel are inaccessible. To accomplish this, the sensor is swallowable, but unlike current gastrointestinal (GI) capsule sensors, the swallowed deployment module auto-implants the sensing package into the GI tract where it remains long-term. In this manner, deep, long-term implantation and the resulting rich biometric set are acquired without the need for invasive surgery or specialized medical personnel.

Travel Grant for presentation and collaborating weith Kenneth Cohen and his NASA associates at InoMedic health Applications, Inc. and KSC
Benjamin S. Terry, Mechanical and Materials Engineering, University of Nebraska – Lincoln, NE

I traveled to the Kennedy Space Center (KSC) and InoMedic Health Applications, Inc. (IHA) on April 29, 2013 to meet with Kenneth Cohen and his IHA and NASA associates Daniel Woodard, Ben Terry at KSCRobert Friedman, and Berta Cohen. The purpose of the meeting was to establish a collaborative relationship between Dr. Cohen’s group (the Kennedy Space Center Biomedical and Engineering Research Laboratory) and the Intuitive Biometrics Laboratory at UNL. I presented our NASA relevant research currently underway that is funded by the Mini Grant: “Noninvasive, Ambulatory, Long-Term, Deep Gastrointestinal Biosensor and Implanter”. The expertise of the group at KSC would clearly augment our core competencies and there appears to be many potential areas for collaboration. The NASA group was pleased with the visit as evidenced by Dr. Cohen's enthusiastic response: "Ben, thanks for making the trip to Florida.  It was great to finally meet you and geek out all morning.  I'm looking forward to potential collaborations.  Your visit generated a lot of enthusiasm." The trip resulted in plans to jointly submit at least two proposals (one to NSF, and one to NASA).

Travel Grant to 2nd Annual ISS Research and Development Conference
Benjamin S. Terry, Mechanical and Materials Engineering, University of Nebraska – Lincoln, NE

The purpose of this grant is to fund travel to the 2nd Annual International Space Station Research and Development Conference. As an investigator interested in conducting research on the space station, I will have the opportunity to discuss two important questions with NASA
attendees: "What can I do on the ISS?" and "How can I do it?". NASA will conduct a workshop that will enable me to take this information and develop my own ideas for experiments using the unique ISS laboratory. Also of keen interest is the International Microgravity Strategic Planning Group (IMSPG), which will meet at the conference. My laboratory is currently developing a new in vivo sensor deployment system to facilitate gathering biometrical data from NASA astronauts and the IMSPG meeting will provide details for testing our work in a microgravity environment.

 

Lily WangHuman Reactions to Noise with Varying Degrees of Rattle or Vibration as Produced by Low-boom Supersonic Aircraft
Lily M. Wang, Architectural Engineering, University of Nebraska Peter Kiewit Institute, Omaha, NE

The goal of this research project is to characterize human reactions to noise with varying degrees of rattle or vibration, similar to those that may be produced indoors by low-boom supersonic aircraft flying overhead.  NASA is interested in developing low-boom supersonic aircraft for commercial use; however, one main concern with deploying such aircraft over land is the detrimental effect that such noise could have on human communities.  Researchers at NASA Langley Research Center have been studying the response to ‘low’ level sonic boom noise by humans within building interiors.  One finding they’ve concluded is that when the boom noise is accompanied with rattle or vibration, produced from the building structure, there seems to be a more negative perception of the noise and greater annoyance.  In this investigation, test subjects are asked to complete tasks and respond to questionnaires, while exposed to noise with varying degrees of rattle or vibration.  Statistical analyses of the results will provide insight on the degree to which noise with rattle or vibration impacts human performance and perception.  Assorted noise metrics used to predict annoyance will also be investigated to determine how reliably they predict human response to noise with rattle or vibration.

 

K. P. RajurkarHigh Speed Electro-Discharge Drilling and Wire Electrode-Discharge Machining of Titanium Alloys for Aerospace Applications
K. P. Rajurkar, Mechanical and Materials Engineering, University of Nebraska – Lincoln, NE

Titanium alloys play an important role in aircraft and aerospace applications because of their high strength-to-weight ratio. Conventional machining such as turning have some difficulties in machining titanium alloys  due to their low thermal conductivity and chemical  reactivity with most cutting tool materials. Wire Electrical discharge machining (WEDM) offers an alternative as it is an non-contact electro-thermal process. This project investigates the effect of machining parameters such as pulse on time, pulse interval, wire tension and wire types on the performance (such cutting speed, surface integrity and wire breakage) of wire  electrical discharge machining of Titanium alloys. Experiments will be conducted using statistical design of experiments approach and surface integrity will be studied with Scanning Electron Microscope and surface profilometer.

 

USLI Team 2013Education and Outreach: University Student Launch Initiative Team at UNL 2013
Kevin Cole, Mechanical and Materials Engineering, University of Nebraska - Lincoln, NE

The best description of the University Student Launch Initiative (USLI) is on the NASA education website. "NASA University Student Launch Initiative, or USLI, is a competition that challenges university-level students to design, build and launch a reusable rocket with a scientific or engineering payload to one mile above ground level, or AGL. The project engages students in scientific research and real-world engineering processes with NASA engineers.”
This competition will last a full eight months of design, testing and building. The competition goes farther than just building a rocket, you also have to: write multiple design reports, conduct video conferences with NASA engineers, and put together outreach events that promote STEM based activities in the community. Our biggest goal for this yea's competition is to provide the best outreach out of all the teams participating.

 

DBF TeamDesign Build Fly Team at UNL 2013
Kevin Cole, Mechanical and Materials Engineering, University of Nebraska - Lincoln, NE

For the 2012/13 AIAA Design/Build/Fly competition, teams must engineer and construct a remote control airplane that can carry various payloads of internal and external missiles with a maximum payload of 3 lbs. The airplane must also be able to take off within a 30 ft by 30ft square.  Light planes with a short wingspan and short length receive higher scores. The UNL Design/Build/Fly team is building a single motor bi-plane this year. The bi-plane configuration makes the plane heavier, but allows it to have a shorter wingspan and greater structural integrity. In addition to building the plane, the competition also requires teams to submit a report that explains the design of the plane and how the design decisions were made.

 

Jun WangADVANCING UNDERGRADUATES' AND GRADUATES' SKILLS FOR ANALYZING THE SATELLITE DATA COLLECTED FROM NASA'S EARTH OBSERVATION
Jun Wang, Earth and Atmospheric Sciences, University of Nebraska - Lincoln, NE

Funds requested for this proposal will be used to support graduate and undergraduate students who have taken or are taking PI’s class “Physical Meteorology”, “Statistical Analysis of Atmospheric Data’, and “Radiative Transfer” to conduct research projects on North American wildfires using the data from NASA’s Earth Observation System, in particular, the data collected from the afternoon-satellite constellations (i.e., the so-called A-train satellites including Aqua, Aura, and CALIPSO). These projects will stimulate the student’s research interests in NASA’s Earth Science, provide much-need hands-on research experiences for students who like to explore the opportunities to join the NASA’s workforce. Based upon the past successful examples of students who conducted the research projects under the PI’s guidance, it is expected that most (if not all) the outcomes of these projects will be used by students to apply summer internship and research fellowships funded by the NASA. In turn, PI will gain valuable experiences in communicating and mentoring undergraduates, a key step in the faculty’s self-development and an integral part for better development of the curriculum for the courses that PI teaches at UNL. Data and software collected by the students will be used as educational materials and in homework designs for this class. The project will strengthen the collaboration that PI has now with the scientists in NASA Goddard Space Flight Center. The expected research results will also have important implications for the air quality management in Nebraska (ie., air division under the Nebraska Department of Environmental Quality).

 

Microgravity 2013NASA MICROGRAVITY SEED 2013
Carl Nelson, Mechanical and Materials Engineering, University of Nebraska - Lincoln, NE

This project's purpose is to evaluate the ability of the Active Response Gravity Offload System (ARGOS) to provide a microgravity environment for a free flying vehicle. To evaluate the ARGOS performance it could be compared to the known microgravity environment generated by the parabolic flight of an airplane. The other option for comparison would be an experiment on the International Space Station. ARGOS is a robotic system that provides reduced gravity environments through a large motion based platform. It is a facility at the Johnson Space Center (JSC) that has been used for human and robotic testing over the past three years. However, ARGOS has not been used for testing free flyers and the evaluation of the ARGOS control system to maintain a microgravity environment for a free flyer is a unique area of research. The student design team will need to develop a free flyer (an octo-copter) that will fly a specific set of motion patterns in both ARGOS and plane induced microgravity environments. A method of collecting data for comparison is required. The data should be a combination of collection methods that may include motion capture camera system and inertial guidance units. Parabolic flight provides an ideal environment to collect a data set for comparison to the data collected on ARGOS. Ultimately, this data will allow the ARGOS system to be evaluated and the control system to be tuned for optimal free flyer performance.

The University of Nebraska – Lincoln’s RASC-AL Robo-Ops team is building a rover to compete in the 2013 RASC-AL Robo-Ops Competition. This competition is an engineering competition sponsored by NASA and organized by the National Institute of Aerospace.  UNL’s team consists of a multidisciplinary team of graduate and undergraduate students. The objective of this competition is for the students to design and build a teleoperated rover that is capable of traveling over different terrains and collecting various target objects with its robotic arm. For the competition, the rover will be exploring the rock yard at NASA’s Johnson Space Center while being remotely operated from the University of Nebraska – Lincoln campus. On the day of the competition, the rover will have one hour to collect as many targets as possible. The targets are worth various points based on their difficulty, and the rover that collects the most points wins this part of the competition. Other aspects of the competition that provide points include education and public outreach, written reports, and a presentation. The team with the most points awarded from all areas wins the competition.

Kevin Cole, Mechanical and Materials Engineering, University of Nebraska - Lincoln, NE

RockSat-C is a program for students to design and build a sounding rocket payload, and launch the payload on a rocket out of Wallops Flight Facility! Payloads shall be student based with faculty and/or industry involvement only. The RockSat-C program actively engages the students through full design-process mentoring, assisting them through the design phase in the Fall semester (CODR, PDR, CDR), and leading the teams through testing and integration reviews and Launch Readiness Review in the Spring. The RSC manager also helps the teams with integration and launch at Wallops Flight Facility!

Our team’s payload consists of two different experiments. The first test is an Electro Hydrodynamic Pump (EHD pump). The second being testing the rigidity of a new 3D printed material known as Polyetherketoneketone (PEKK). This material was printed into two plates that hold the batteries for the computers systems that regulated the EHD pump. The battery plates are being tested for deflection with string gauges.

Tomas HelikarDynamical Visualization of Large-Scale Models of Network-Like Processes
Tomas Helikar, Mathematics, University of Nebraska at Omaha, NE

The high complexity of biochemical networks necessitates the world-wide scientific community as a whole to study and contribute to evolving, globally shared models of biological processes. Our group launched a new collaborative platform, Cell Collective (www.thecellcollective.org), for creation and simulations of  computer models of complex biological systems. The technology has unique features that enable scientists to simulate biological systems in an intuitive fashion and in real-time. The purpose of this project is develop a new tool which will also enable researchers to visualize the structure of complex, network-like processes. Much like a house blueprint, this will provide scientists with the ability to visualize the various components of biological process from a holistic perspective, making it easier to further investigate the process as related to normal as well as malfunctioning states. Furthermore, the technologies around which this proposal centers are becoming the centerpiece of new classes developed at UNO to promote STEM education; hence further development and support obtained through this project will be an important step for continued efforts in the STEM education direction.

This project encourages women to consider academic majors and careers in information technology through activities that expose students to the opportunities available in the information technology field through the development of a speaker series and demonstrate the need for more diversity in the field of information technology.  The speaker series will include a member of NASA’s Johnson Space Center Speaker’s Bureau to highlight the opportunities in technology at NASA.  We will also invite local and national figures from industry or academia to highlight the diversity of careers and people in technology.  To raise awareness about the need for diversity in technology careers, we will initiate a local “Red Chair Campaign” (www.sitwithme.org) to highlight the need for more women and diversity in the technology field.  This campaign will allow us to reach out to students, faculty, staff, and local organizations about the value and desire for more diversity in technology-related majors and careers.

 

Daniel BlankeNovel Assistive Locomotor Tool for Gait Rehabilitation in the Elderly
Daniel Blanke, Health Physical Education and Recreation, University of Nebraska at Omaha, NE

The goal of this research is to investigate the effect of horizontal assistive forces on gait variability, a natural and important feature of human movement, in older adults. This novel approach has exciting potential for therapeutic applications in the prevention of falls. Falls are a major issue facing older adults, affecting one out of three adults over the age of sixty-five every year. Gait variability has been strongly associated with the incidence of falls amongst the elderly. Our preliminary research has revealed that gait variability can be altered by applying a horizontal assistive force to a person while they walk. This has been demonstrated in young, healthy subjects. Similarly, our computational models have shown that the application of assistive forces can alter gait variability. However, the effect of these forces on the gait variability of the elderly populations is, as of yet, unknown. An experimental apparatus will be constructed that applies horizontal assistive forces to subjects as they walk on a treadmill. Gait variability will be compared between non-assistive and assistive conditions in healthy young and elderly subjects. Both young and elderly subjects will then participate in a six-week training program. Each age group will be split into an experimental group, training with horizontal assistive forces, and a control group, training without horizontal assistive forces. Gait variability will also be measured twice at one week intervals after the training program to test for retention effects. The proposed research will further our understanding of gait variability as it relates to aging, and most importantly how amenable it is to training under these conditions. Results of this research will lay the groundwork for the development of innovative rehabilitation protocols to improve physical function and decrease risk of falling in older persons.

PosterInquiry-Based Early Undergraduate Research Using High-Altitude Ballooning
Kendra Sibbernsen, Metropolitan Community College, Omaha, NE and Michael Sibbernsen, Strategic Air and Space Museum, Ashland, NE

One common objective for undergraduate science classes is to have students learn how to do scientific inquiry. However, often in science laboratory classes, students learn to take data, analyze it, and come to conclusions, but they are told what to study and are thus denied the opportunity to ask their own research questions, a crucial part of scientific inquiry. A special topics class in high-altitude ballooning was offered at Metropolitan Community College, a large metropolitan two-year college in Omaha, NE, to focus on scientific inquiry for the participants through support of NASA Nebraska Space Grant. Weather balloons with payloads attached are launched to near space where the balloon bursts and falls with a parachute back to the ground. Students worked in small groups to ask their research questions, they designed their payloads, participated in the launch and retrieval of equipment, analyzed data, and presented the results of their research. This type of experience has potential uses in physics, physical science, engineering, electronics, computer programming, meteorology, astronomy, and chemistry classes. The experience also serves as a stepping-stone between developing rocket payloads and designing satellite payloads. Results from student work are shared, as well as student responses to the experience and suggestions for administering a high-altitude ballooning program for undergraduates or extending inquiry-based ballooning experiences into high-school or middle-school.

During long-duration space travel, using teleoperation through interactive telepresence may be the only viable option for providing for health care. With the support of NASA Nebraska EPSCoR Mini-grant, our multidisciplinary research team (Dr. Oleynikov from UNMC, Dr. Nelson from UNL and my research team) will develop a new Virtual Simulator with Modular joystick for Teleperation (ViSMoT). We will investigate the impact of ViSMoT on teleoperational skills performance among performers of different surgical experience levels and compare the effectiveness of the ViSMoT with a traditional surgical box trainer on teleoperational skills performance among performers of different surgical experience levels. The goal for this project is to establish a new generation of virtual training environment with flexible modular control interface for trainees to learn teleoperational skills more efficiently. More importantly, the new training environment can be useful for learning how to remote control robotic arms in the international space station.
