Halfway to Space

This blog is an update to Cooper’s first blog: Aiming for Space with a Fully Reusable Rocket

Hi again! I am Cooper Eastwood, an Aeronautical Engineering sophomore and co-investigator of the Embry-Riddle Suborbital Reusable Vehicle. The whole world put itself on pause and everyone felt the effects. I know that at my home in Los Angeles many businesses and everyday workers have been forced inside due to the pandemic. Online learning, commerce, and communication became the new norm. I and many others have witnessed the whole world adapt and change in only a few months. Now almost a year later much has changed but the goal is always the same: to get to space cheaper and more often.

The Embry-Riddle Suborbital Reusable Vehicle (ERAU-SRV) team transitioned completely online during the summer period. Gaurav Nene and I stayed on task even in different parts of the country through video calls and scheduled meetings. Our small integrated team dynamic allowed us an easy transition as we can continue working diligently on the next steps of development whenever necessary. During this time, we submitted the lengthy and necessary documentation for unguided commercial suborbital vehicle launch approval at Spaceport America. We coordinated documentation with the FAA’s Office of Commercial Space Transportation (AST) and the New Mexico Spaceport Authority. Then in June 2020 we received the launch approval for a future date in 2021. We are taking our two-stage launch vehicle past the Karman line, or 100 kilometers, and to do so we need to launch from an FAA licensed facility. As New Mexico begins the process of allowing more frequent travel to their federal sites, the team will be at Spaceport America to observe the launch facilities and finally meet the ground support members.

To get the final funding we needed to finish the vehicle. The College of Engineering, the Undergraduate Research Institute, and Embry-Riddle’s Daytona Beach campus opened an opportunity for student projects to win grant funding by presenting in front of the Board of Alumni. Dr. Ron Madler, Dean of the College of Engineering, extended an invitation for us to further our research and break new ground with this brand-new alumni collaboration. We submitted a proposal to the board, bidding for a chance to present. This contained our preliminary design review, our FAA package, and the AIAA published technical report regarding our avionics. We qualified as one of the top three finalists and in under a week we made our presentation. Once the dust settled, we were awarded a grant to accelerate our work! With this new thrust of momentum and enough funding to purchase the rest of the booster stage, the next step in our engineering method was to verify our vehicle.

We required a launch test of our sustainer to accomplish six objectives: verify performance and our trajectory models, qualify the structural components, validate the recovery system, validate performance of telemetry, gain experience with pre-launch operations, and gain post-launch operations experience. After five days of integration we put the vehicle on the pad at Friends of Amateur Rocketry launch site in Mojave, California.

On December 19^th, 2020 at around 12:30 PM, the rocket was launched and experienced a recovery system failure at apogee which was addressed in a 35-page post-flight report. The sustainer surpassed its goal of 31,666 feet – exactly 6 miles. The vehicle was only partially recovered due to ballistic reentry, however we received two sets of flight data from our identical on-board computers. Every piece of the rocket was sifted from the sand, meticulously inspected, and documented. By finishing the in-depth report we completed five of our six objectives and proved that we could take the step forward on construction of the booster stage to launch at Spaceport America.

Recover and inspection of the rocket underway. We found parts to the GoPro, Spot Tracker, both AIM XTRA computers, as well as all the body components. Due to this inspection we found the root cause of the failure.

Immediately after our test we welcomed a new faculty advisor as well as a member of our team. Our previous faculty advisor Dr. Michael Fabian moved on to government research and Prof. Robert Gerrick, Mechanical Engineering Chair, took the role of our mentor. William Knoblauch, a Mechanical Engineering freshman, also became a member of our team by assisting in post-flight analysis and continuing testing research on flight critical hardware. We are in the process of accepting new members aiming to grow hands on experience with suborbital launch vehicles. As our vehicle and team grow, so do our hopes of surpassing our goals.

When the previous post left off, we were anticipating a trip to Portland, Oregon to attend the American Institute of Aeronautics and Astronautics (AIAA) Student Conference Region VI and present a 30-minute presentation on our avionics system at the conference. This was cancelled only a week before taking place in March 2020 and was postponed until the same time this year. Now after resubmitting the paper to a judge’s panel for review, it was accepted to the 2021 student conference at California State Long Beach and will be taking place in April.

Being a cross-discipline undergraduate research project gives us the opportunity to collaborate with a diverse group of engineers who can all contribute to space flight. As we expect many more space launches, the amount of experimental data gained per flight will be exponential. After a successful launch we will be calling on all students and as well as those considering enrolling at Embry-Riddle Prescott to form ideas, build hardware, and program experiments for the vehicle. These will all be taken to space, an environment that can be exclusively reached repeatedly only at Embry-Riddle. If you have a great idea and a goal, you really can get to space with the College of Engineering and the Undergraduate Research Institute’s backing.

The Trace Evidence Analysis of Makeup

Posted on January 4, 2021 by Embry-Riddle Aeronautical University

by MaeLee DeVries

My name is MaeLee DeVries and I am a senior at Embry-Riddle Aeronautical University (ERAU) in Prescott, Arizona. I am majoring in Forensic Biology and I am interested in trace evidence, which is why I chose the research topic of trace evidence of makeup. We’ve all seen it on crime shows, there’s a piece of evidence that could not have been found, but somehow the investigators are always able to trace it back to the perpetrator in the end. While that is not wholly reality, it is not completely far from the truth either. Trace evidence can be very difficult to deal with because it is difficult to see, difficult to handle, and even more difficult to avoid cross contamination. However, if done properly, the analysis performed on trace evidence can corroborate stories and determine the truth. This is why I wanted to do this research because the more data there is, the stronger statistical values can be, which can create more conclusive evidence. Hopefully, this research helps contribute to a usable and searchable database for makeup to help investigators speed up investigation processes and be more objective in their investigations. After all, objectivity is one of the main goals of evidence-based research because it excludes bias and seeks the truth.

To be able to do this research, I had the privilege of receiving a Space Grant and being selected to be funded for an Ignite Undergraduate Research Project during the fall semester of 2020. The goal of this research was to support and develop a method for easily distinguishing the morphological and chemical features of various lipsticks and eyeshadow palette samples. There is a lot of data that still needs to be collected in trace evidence analysis of makeup research to fill the gap of information that exists; therefore, this research will demonstrate nondestructive analysis techniques that can help trace the evidence back to its source by providing more data that can be utilized in crime laboratories to assist in solving crimes. As the project leader and the only student on this project, my duties were to prepare the research samples, analyze the samples using a light microscope, Fourier-Transform Electron Microscopy (FTIR), and learn how to use the Scanning Electron Microscope in tandem with an Energy Dispersive Spectrometer (SEM/EDS) to analyze the potentially toxic chemicals within and individualistic characteristics of the different brands of makeup samples

*Highly esteemed engineer, Dr. Lanning, teaching me how to use the SEM/EDS*.

In this research my mentor, Dr. Teresa Eaton and I studied three different brands of eyeshadow and two different brands of lipstick. Originally, we were going to study six different brands of eyeshadow palettes; however, due to this being my last semester, time constraints did not allow me to study all of the samples I would have liked to; therefore, we studied palettes from Maybelline, Revlon, and Milani and a red lipstick sample and a pink lipstick sample each from Milani, and Wet n Wild. I did, however, run into some hiccups along the way, which is nothing new if you are familiar with research. First, preparing the samples took much longer than expected due to the meticulous cleaning and recleaning of materials to avoid cross contamination. When dealing with evidence, this is paramount. The second problem I ran into had to do with the SEM/EDS. While I was in the middle of viewing and analyzing my samples, the filament on the SEM/EDS burned out, putting my entire project to a halt. The filament allows for the visualization of the samples because that is where the electron beam originates, which without, the visualization is not possible. Obviously, I cannot research blindly; however, the kind Dr. Lanning (pictured above) came to my rescue, replacing the filament within hours. These roadblocks were impeding, but I got past them and was able to complete what I could of my research.

I analyzed a total of 37 samples viewed under the light microscope and analyzed using FTIR and 41 on the SEM/EDS, so a lot of samples were run, just not all of the samples I wanted to analyze. The techniques used were not invasive, other than the SEM/EDS and were able to discriminate between palettes, but not individual samples. FTIR was not invasive and quick, but only showed a fingerprint, while SEM/EDS was destructive, but showed the chemical composition and only used a very small amount of sample.

Optical Microscopy Images

Figure 2. Maybelline eyeshadow
Figure 3. Revlon eyeshadow

FTIR Spectra and Data

*Graph 1. Sub-sample 1b compared to TALC in an FTIR spectrum.*

*Graph 2. Sub-sample 2b compared to Silicon in an FTIR spectrum.*

As you can see, Figure 1, 2, and 3 demonstrate the light microscopic view of a Milani eyeshadow sample, a Maybelline eyeshadow sample, and a Revlon eyeshadow sample, respectively. In my observations, I noted signature red-pink circular particles in nearly all of the Milani eyeshadow colors, which can help distinguish the samples from other palettes. In the Maybelline reflective eyeshadow sample glass-like and other reflective and metallic-like particles were noted, which were consistent with most of the shiny and glimmering samples. The Revlon eyeshadow was fine and fibrous, which was common throughout the more neutral and less glittery and shiny eyeshadows.

Graphs 1 and 2 are both FTIR spectra and show that there is a broad band at around 1000 in both sub-samples 1b and 2b. This was the same amongst nearly all of them, but other peaks helped differentiate between palettes based on what the chemical fingerprint was most likely related to. Most of the sub-samples from Sample 1 (Maybelline) were related to TALC, most of the sub-samples from Sample 2 (Revlon) were related to silicon, and most of the sub-samples from Sample 4 (Milani) were related to paraffin. This simple information is significant due to the differentiation it provides between palettes.

SEM/EDS Images and Data

Figure 4. Revlon eyeshadow

Figure 4 shows the SEM image of eyeshadow sub-sample 2a by Revlon. The elemental composition is shown to the right demonstrating that there are two heavy metals that were not expected to be within this sample, Tc and Bi. Both are not toxic at low levels.

Figure 5. Maybelline eyeshadow

Figure 5 shows the SEM image of eyeshadow sub-sample 1i by Maybelline, which demonstrates expected heavy metals such as Fe, Cu, and Zn.

Figure 6. Milani eyeshadow

Figure 6 shows the SEM image of eyeshadow sub-sample 4e by Milani. Again, expected heavy metal content is observed as well as cylinders of carbon suspected to be some form of microplastics.

Figure 7. Wet n Wild lipstick

Figure 7 shows the SEM image of lipstick sample 16 by Wet n wild. Expected chemical composition is seen.

Finally, Figures 4, 5, 6, and 7 show the images from the SEM and the chemical composition from the EDS for eyeshadow and lipstick samples. Figure 6 shows that there are some heavier more toxic chemicals in the sample compared to the other samples, but these chemicals are not toxic to humans at very low quantities. There were no distinct chemical differences between the palettes other than Sample 2, which had Technetium and/or Bismuth in several of the samples. The SEM images were quite fascinating to look at, and while each sample did look different in its own way, it would be a subjective way to look at evidence and as I said earlier, that is not the goal of trace evidence.

*This image shows me preparing the eyeshadow makeup samples and preventing cross contamination where possible.*

My final results for this research project indicated that the chemical analysis techniques, FTIR and EDS, can potentially differentiate between palettes, but not individual sub-samples, while the optical microscopy techniques, light microscopy, and SEM, may be useful in differentiating between sub-samples in color and morphology. However, as I mentioned above, this process is much more subjective, and it is important to have objective methods of analysis in trace evidence. This analysis is not discriminatory enough by itself to differentiate between individual sub-samples, though it may be useful for differentiating between palettes. In the end, there was ample data gathered that demonstrated elemental, morphological, and spectroscopic properties of the samples for results and future analyses.

In conclusion, I hope this is not the end of this research because there is so much potential that this type of research has to assist crime laboratories in reaching the truth faster and more objectively. The opportunity I have had with this research project has yielded great experience and understanding for me in the future. Personally, I want to be a forensic DNA analyst, which must be an objective analysis technique, because the main goal is providing the truth. Not who we think did it. DNA analysis uses databases, which are crucial to conclusions; however, DNA cannot act alone in submission of evidence. Stories and other trace evidence must align in order for the truth to be found; therefore, other forms of trace evidence are vital and necessary. I love science and the potential it holds. After all, it is prepared to provide the truth, if we handle and analyze it properly.

My Experience at Northrop Grumman as a Freshman

Posted on September 10, 2020 by #ERAUPrescott

by Devon Kisfalvi

*A picture of me at Willow Lake near the Embry-Riddle Campus*.

My name is Devon Kisfalvi and I’m a part of the class of 2023. My major is Electrical Engineering with a minor in Systems Engineering. My amazing internship experience started January of 2020 before the start of the Spring 2020 semester. This internship wouldn’t have been possible without Embry-Riddle. I had just finished my first semester of freshman year, and became a member of the IEEE (Institute of Electrical and Electronics Engineers) Club on campus. Through them I was able to get a membership with IEEE, learn about the 2020 IEEE Rising Stars Conference, and was able to attend. There I saw Northrop Grumman had set up a table. I went over and introduced myself, and after talking with them they asked for a resume. One of the managers from the Gilbert, AZ office who was at the conference offered me a summer internship.

The internship started May 2020 and was amazing! Even though coronavirus affected most of the in-person events being held, Northrop Grumman was able to still offer multiple opportunities for the interns to meet people and learn more about the company. During my internship I was working with the avionics team on two different projects. The first was working with the internal research and development team on looking for new parts to improve one of the critical systems of a satellite project. This research involved replacing one of the components that would have to be specifically constructed to meet the requirements set by Northrop Grumman and NASA. I communicated with a handful of companies that manufacture those components to ensure that they would meet Northrop Grumman’s and NASA’s requirements.

The second task I worked on with my mentor was collecting documentation for the Landsat 9 (L9) team on the Integrated Electronics Module (IEM) focusing on End Item Data Package (EIDP), which is the final stage of after environmental testing. The documents that needed to be included were parts lists, assembly drawings, among other reports.

*Construction of the Landsat 9 at Northrop Grumman.*

Even though I was just a freshman, the relevant coursework I have taken so far helped me out a lot, like Intro to Engineering (EGR 101), Digital Circuit (CEC 220), and Digital Circuit Design (CEC 222). EGR 101 has helped develop my teamwork skills to effectively communicate and work with teams of any size. CEC 220 helped me understand the coding of Field Programmable Gate Arrays (FPGA), logic of electrical circuits, and how logic circuits connect to create complex devices. CEC 222 helped me understand the basic components of electrical circuits and how they worked. All these classes helped me with my internship.

*The Landsat 9 that I worked on at Northrop Grumman.*

Even though you might only be a freshman there is still a possibility for you to be able to do an internship with a company. One thing that employers look for is how you act and how you present yourself. One key aspect is communication, both verbal and written. Anyone can come up with amazing ideas, but you need to be able to communicate them. You also will most likely be working with teams of people and you need to be able to communicate with your team to be successful. You also have to remember how you present yourself to employers. You must be professional, but you also must be yourself. Go into any possible situation with a smile and make sure to introduce yourself. Start a conversation with them. For example, you could ask a question about the company or something specific that interests you. This shows that you are interested in their company, and leads them to asking you questions about yourself. Embry-Riddle has helped me out so much and as you stay open and professional, anything is possible.

A Great Start to Senior Year

by Bria Booth

Hello everyone! Summer has finally ended. This year, I felt so ready to get back into classes. It’s been about six months since I’ve been able to see friends and learn in a classroom. I moved back to Prescott two weeks ago to celebrate my friend Vee’s birthday.

Our freshman year, Vee and I lived in the same dorm! We met on the “Schools App” a few months before move-in and got to know each other. Though we don’t live together anymore, she’s become one of my closest friends. The people that I met my freshman year are all so important to me. We’ve grown and faced challenges together. Our friend Grace falls into that same category. She was a part of my orientation group, and we ended up getting along really well. Grace and Vee have been my family while away from home. We all made sure to socially distance before seeing each other in person. We’ve been keeping to pretty small social circles during the summer, so it was nice to be able to hang out with friends.

Myself, Vee, and Grace at Dutch Bros. coffee before the pandemic.
At Alphi Xi Delta’s 2019 formal. Grace is part of the sorority with me, and Vee was one of our guests.

To celebrate Vee’s birthday, we visited Grace’s parents in Tubac. We spent a few relaxing days there swimming, looking after newly acquired plants, and making pizza. When we got back to Prescott, Vee planned a socially distanced birthday outing with a larger group of friends. We all brought blankets and masks and shared stories from summer.

Classes are quite a bit different than last year. About half the time, I meet with my class online, and when classes are in-person, we sit at every other chair. I’d be lying if I said it wasn’t going to be an odd semester, but I’m really looking forward to my classes. So far, I’m the most excited about my Capstone. Yesterday we were assigned our groups and projects. I’ll be working on Attitude Reaction Wheels. Our group is picking up where a capstone team from last year left off.

At Embry-Riddle in Prescott, an Engineers Capstone project takes two semesters. The first is focused on Preliminary Design and the second is Detail Design. The goal is to have a prototype built by the end of our senior year. It’s still hard for me to believe that I’ve started work on the biggest project of my four years at Embry-Riddle.

Over the last week, I’ve had so many people reach out about my first blog post! I’m happy to see that so many people seem to be excited about it. I’m looking forward to sharing my experiences on campus, but I’d also love to hear from you about what you’d like to hear about. Feel free to comment on this blog post with subjects you’d like me to write about!

A Flight Lead Student Advisor’s View From Above

Posted on April 20, 2020 by Student Spotlights

Hi there! I’m Martin Kurkchubasche, a Senior studying Aeronautical Science with a minor in Aviation Business Administration. I’m from San Jose, California and I came to Embry-Riddle Prescott having already earned my Private Pilot Certificate with just about 100 hours of experience. This put me on track to graduate a semester early, December 2020 instead of May 2021. Throughout my time here, I have earned my Instrument rating and finished my Commercial Single-Engine training in our Cessna 172 fleet and am now in the process of earning my Commercial Multi-Engine training in our Diamond DA 42 fleet.

I am also a FAA-certified Advanced Instrument Ground Instructor and work as a Peer Counselor where I tutor students, endorse written exams, and for the past year I have taught labs for the College of Aviation. During the school year, there’s a very high chance you’ll find me in the Hazy Library until closing working with students. During admissions events such as Preview Day and Orientation, you’ll probably see me rocking out with our two awesome College of Aviation advisors Merrie and Stacey. I help create schedules for all you students and I make sure you end up with my favorite professors! For those of you reading this, we’re currently dealing with COVID-19. So, for any of my students reading this, I’m very proud of the work you all have completed as well as your adaptability and ability to deal with anything the world throws at us!

My involvement with our Flight Department and Flight Line is extensive. As the Lead Student Advisor for the Flight Department, I work one-on-one with management and help take suggestions students have and implement them at the Flight Department. As a student myself, I was always uncomfortable talking to my higher ups, which is why our department chair refers to me as his “feet on the ground”. I make sure students have someone they can comfortably talk to and share experiences, good or bad. I am incredibly lucky to be able to work with and call everyone in management a friend. If you’ve been at any of the admissions events, there’s a very high chance you’ve met and talked with me during the Flight Breakout Sessions. I have a great team of flight students that help me out and sit on the Flight Line Student Advisory Board and help plan student-led workshops on tough topics, and plan special events like socials and barbecues. I’m always looking for volunteers to be on the Advisory Board so swing by my office at the Flight Department and say hi!

*Photos from when I was observing a demo-flight when Cirrus was demonstrating the ability of their SR-20 aircraft as a possible trainer for ERAU.*

You’ll also find me working behind the desk as a Flight Dispatcher and occasionally on a shuttle-run as a Shuttle Driver. I also sit on our No-Show Review Board where I take part in the determination if we should excuse a no-show or reduce costs of unexcused no-shows. The Flight Department always jokes about getting me a name tag reading, “Ask me, I probably know” because of the variety of qualifications I hold. I work on special projects, most recently having participated in helping choose the new fleet for ERAU, migrating our Dispatch team from a paper schedule to fully online, redesigned the entire shuttle route to make it easier for our students to make it from class to our Flight Line, and am currently taking part in helping select the new software to replace our Dispatch / Scheduling / Academic Tracking software.

I am on my third summer working for our Summer Programs Department, second summer working as a Housing Supervisor. I visit our office frequently because, quite frankly, I love the people I work with. I worked as a Teacher’s Aide throughout high school teaching 4th through 8th graders photography, so getting to teach high schoolers about aviation is probably one of the most fun things I’ve gotten to do. Also, shout out to Wendy, Shelby, Tori, Seyi, Logan, and Hayden over in the office! Hopefully I’ll see you all soon for the summer kick-off! I’m looking forward to my final year working with Summer Programs!

*The 2019 team from our Summer Programs Department.*

In my free time, I fly, believe it or not. I have over 300 hours of experience in a wide variety of aircraft. I earned my High-Performance and Complex Aircraft endorsements flying the most unique plane in the Prescott fleet, our 1980 Cessna 182-RG, affectionately known as Riddle 82. Sometimes I even fly two different types of planes in one day. One of the most memorable experiences was flying Riddle 82 in the morning with one of our Training Managers and going straight into Riddle 94, one of our Diamonds, with our Chief Pilot. If you ever see me in person, please ask me about it! There’s more that happened that’s just too much for a blog!

*Team 3 Training Manager Dave Warnke and I taking off in Riddle 82 in 25-knot winds at Prescott, taken by Instructor Cameron Rojas through binoculars.*

I’ve flown almost every Cessna 172 model from 1970 onward. I’ve done cross country flights to Vegas, up and down the California coast, and all throughout Arizona. Through my time as a Peer Counselor and my flight experience, I’d like to believe I’ve become an expert with the Cessna 172, but there’s always more to learn and experience. As students we never stop learning about the planes we fly.

My roommate took this photo of me relaxing on a bench at Arizona Snowbowl Ski Resort after a long day on the slopes.

When I’m not in the air, I try to stay active and take advantage of the weather we have. In Prescott, we’re about 20 degrees cooler than Phoenix on any given day, which means I can be outside year-round and not hiding from the heat. When the weather is good, I can be on our tennis courts hitting with my friends or relaxing poolside watching planes fly over. Sometimes I’ll make the dive down to Phoenix and hang out at the air-conditioned malls in Scottsdale. When it’s winter and we have snow, find me on the slopes in Flagstaff with my buddies.

As if I weren’t busy enough, I also run a research program with the Undergraduate Research Institute. This involves me running a brand-new virtual reality lab which is located at our Flight Department’s Simulation Center. The project was started by one of my professors, Professor Michelle P. Hight. I’ve been working with her from the beginning of the project and have become the resident student expert on flight simulation under VR. I have two awesome research assistants who I couldn’t work without. They happened to be two of my friends, Jake and Daniel. Jake and I were almost-neighbors freshman year, he lived one suite away from me in the Mingus Mountain Complex and I happened to be friends with his suite-mates, so I was always invading their dorms. Daniel is a sophomore who I met through my work as the Student advisor to the Flight Department and we immediately clicked. Our goal is to reduce the cost of flight training and hopefully play a part in reducing the global pilot shortage. I’ve presented at the Industry Advisory Board in front of many major companies. It’s only been our first semester working, and we didn’t get to do very much due to the on-going pandemic, but we’ve adapted and changed everything we’re doing. Right now, we’re designing an experimental course that will hopefully be offered by the College of Aviation in the fall! So, for all you incoming students, keep an eye out for the course offering and I might get to be your teacher!

Research Opportunity for Undergraduates in Autonomous Vehicles

Posted on September 4, 2019 by Student Spotlights

by Andrea Gray

This past summer I was privileged to work as an undergraduate on a National Science Foundation funded research project at Wright State University. This research program was focused on autonomous vehicles and split up the 11 participants into 4 separate teams working on specific research and development projects under the general topic of autonomous vehicles.

I was on a team with another undergraduate student studying Electrical Engineering working on developing a forward collision detection and avoidance system in autonomous ground vehicles using LiDAR and IBM’s 90nm CMOS technology. As a Software Engineering student, the focus of circuit creation and design was not something I was familiar with, but luckily, I had a wonderful teammate and supervisor, along with the experiences I have had at Embry-Riddle, I was able to learn and be successful in my work.

LiDAR is growing in popularity with autonomous ground vehicles due to their ability to function in adverse weather conditions (comparative to a camera) and their recent decrease in cost. The 90nm CMOS, Complimentary Metal-Oxide Semiconductor, is being used along with the LiDAR because it is a low-power and low-space solution that can also produce the necessary performance needed to make rapid decisions for the system. This LiDAR system, being low-energy and high-performance, is a development that is highly valued in the autonomous ground vehicle field. While there are many teams performing research and development for systems such as this one, there is no system that has been adopted by commercial or professional companies as there is still a lot to be perfected in the systems and costs can still be too high. This is where our research shows its value, since LiDAR is rapidly dropping in price and our system is based on dependability, our final design and report should be very useful for others in the field after presented at a technical conference at the end of this year.

For the development of this system, we first designed the basic circuitry logic in MATLAB. This process was where I was able to take the lead from my previous MATLAB and Simulink experience and develop a basic functional forward collision detection and prevention system. From there, we exported the circuit into a software platform called Cadence. Cadence allows for circuit development that meets the specific specifications and functionalities of particular technologies per their manufacturer’s specifications. My teammate, being familiar with Cadence, took over the circuitry design while I did more research on issues that would need to be mitigated with LiDAR systems such as the detection of the return LiDAR pulse off of obstacles with poor reflectivity rates (i.e. matte black bar bumpers). My teammate navigated the complex Cadence design process, with my research inputs, and we were able to successfully create our final circuitry system for a forward collision detection and prevention system for an autonomous ground vehicle.

By the end of the 3 months, I had gained a large understanding of autonomous ground vehicles, their history, and their future. I produced a background report, multiple progress reports on the technology we designed with their setbacks and future plans, and I am currently working on the final report of the project, along with my teammate, which is planned to be published into a conference by the end of the year. Along with knowledge gained on the topic, I learned an immense amount about perfecting my time management skills, my teamwork abilities, and, a vital skill for engineers, the ability to create a professional technical report that is well-organized and well-written all while being completed under a strict time constraint. I am very grateful for not only this experience, but also for the knowledge gained during it and the knowledge I was able to utilize from my academic career at Embry-Riddle.

Luke Baird’s REU at Wichita State University

Posted on August 23, 2019 by Student Spotlights

This past summer, I attended an REU at Wichita State University in Kansas. I originally heard about the Research Experiences for Undergraduates (REU) program in an email from Dr. Ed Post, advertising the REU in Cyber-physical systems, along with several other REUs. REUs are summer research internship programs at different universities throughout the country funded by the National Science Foundation in science, technology, engineering, or mathematics. With the support of several professors in the Electrical Engineering department at Embry-Riddle, I was readily accepted into the program.

Before, I had zero experience whatsoever with research, however, the program provided a smooth introduction to it. My work schedule was super laid-back. Once a week, I would meet with the program coordinator for different workshops discussing topics such as how to apply to graduate school, what is expected in research, and how to present research findings effectively. Also, I met weekly with my faculty mentor regarding the specific research in which I was involved. As a result, I needed to employ a lot of self-discipline. Thankfully, I formed good study habits at Embry-Riddle that I applied at the REU.

When I was in high school, I had a job with a marketing company developing mobile apps. Based on this work experience, the program coordinator paired me with a project in the field of Android cybersecurity. It was my task to research and develop a set of tools to determine if a given app on the Android platform is hiding in different lists on a device.

At a poster session featuring my work with Android.

One of my favorite things about Kansas is that the people there are remarkably hospitable. Within days, I had the opportunity to make friends both with other REU interns and with several local residents through a college group and a local church. This was a huge blessing as I did not have a car in Kansas.

Towards the end of the REU, I had the opportunity to visit Hutchinson, KS where NASA’s Cosmosphere is located. Their lobby is built around a SR-71 Blackbird banked 30 degrees for its turn to final.

One of the coolest things that I got to see there was the original Apollo 13 space capsule, reassembled after different parts toured the world for many years. It was particularly interesting to see the history of rockets from World War II through the space race. As an American, I was quite unfamiliar with the German and Russian history which was covered extensively and honestly in the museum.

Currently, I am finishing up the paper that was mostly completed during the REU. It is wonderful to be able to show a completed paper at the end of a program, especially as an undergraduate. I went from not knowing a thing about research to having a finished paper. My mentor and I are submitting the paper to a conference which I will hear from by the end of the month.

To any students who are interested in research—I would highly recommend an REU, especially for Sophomores as REUs accept Sophomores far more readily than industry internships do. There was even an intern who had only completed his freshmen year who was accepted! I am thankful for Embry-Riddle making this wonderful opportunity possible for me this summer!

Making Graphene Composites Thanks to URI

Posted on September 13, 2016 by #ERAUPrescott

I’m Trupti Mahendrakar from Bangalore, India. Exploring and innovating is my passion. I joined Riddle in Fall 2015. Since then till now, I was encouraged and motivated to do what I like. Professor’s here are so helpful. The entire institution makes me feel at home. My first semester here, I came up with an idea of making Graphene based composites. Later, I got to know that the University encourages and funds student researches through Ignite or Undergraduate Research Institute (URI). All I had to do was to find a Professor who can help me with my project and find a group of people who are interested. Thus, I started Alternate Composite Team (ACT).

Here’s a little information about Graphene. It is a new material discovered in 2004. It is known for its extraordinary chemical and physical properties. Also, it is an allotrope of carbon. Embry-Riddle made is possible for me to work on this amazing material and pursue my goal in making graphene based composites for aircrafts and rockets. To know more about my project, feel free to email me at mahendrt@my.erau.edu

Here are some pictures of me and my team working. It may not look fun but remember “Appearance can be deceptive.” So come on over and try it yourself.

Engineering skills!

LIGO Proved Gravitational Waves Exist and I Helped!

Posted on February 17, 2016 by #ERAUPrescott

Well the cat’s out of the bag: the Laser Interferometer Gravitational-Wave Observatory Collaboration, or the LIGO Collaboration, has detected and confirmed the existence of gravitational waves. Finally, I don’t have to giggle to myself as my friends ask why I am doing research on a project that had such a small chance of success. Finally, I don’t have to keep secret about one of the biggest discoveries in the modern science, something I have known about since September when it was detected. It is an exciting time, not just to see the amazing results of a project that I am a small, insignificant part of, but also because that means that a completely new field of research has just opened up, gravitational wave astronomy.

Gravitational wave

First, let me explain a bit about gravitational waves, if you haven’t already seen the countless videos. Gravitational waves were first predicted by Einstein in 1916 when he formulated the idea of general relativity.

Blackhole

Collision

In essence, they are the perturbations, or ripples, in the fabric of space and time. They are emitted from massive systems, like coalescing two black holes converging and merging into one, which is actually what LIGO detected, or giant cataclysms like supernovae. They are a confirmation of a theory we have been using for a century, but they are also a new tool we can use to probe the universe. As the comparison goes, “As Galileo’s telescope opened our eyes to the universe, gravitational waves have opened our ears.”

The best part is that I can be a part of the research during this era of discovery, even though I am only an undergraduate student. Embry-Riddle is a host to many esteemed faculty that do research and encourage their students to do research, and there is an entire department dedicated to student research in the form of the Undergraduate Research Institute run by Dr. Anne Boettcher. In fact, three professors in the physics department – Dr. Michele Zanolin, Dr. Brennan Hughey, and Dr. Andri Gretarsson – are involved in the LIGO experiment, and actually are the only scientists in the whole Four Corners area (Arizona, Utah, New Mexico, and Colorado) that are pursuing this research.

Research for undergraduate students is incredibly important, but also highly demanding. I work ten hours a week, reading papers on high-level statistics, writing proofs, learning to code, and analyzing data. It requires a lot of concentration and persistence, especially since I have had to learn a completely new set of skills and knowledge. And it means that as a student, I have to take initiative and follow through on something I am not receiving a grade for. But in the end, I don’t regret it, since I was able to sit in the conference room at 8:30 am and watch the live press release of something amazing. Since I was able to be a part of something bigger than I was. Since I have learned so much about something so fascinating that otherwise I would have known nothing about. And in the end, we discovered gravitational waves!

Fall 2015. Senior Year. Capstone. Yes!

Posted on September 23, 2015 by Cherie

Hey there fellow students/potential students here’s an update on how my first month back has been! So, as you know, I am a senior in Aerospace Engineering and this semester I am working on the Preliminary Aircraft Design course of my Capstone Project. It has been pretty fun so far but is definitely hard. The courses you take prior to the capstone do help out a lot in your preparation for designing an entire aircraft from scratch. But really how cool is that — an entire aircraft from scratch!

I am also continuing to pursue the research I was working on over the summer. Hopefully, the data processing will allow us to write a paper on the research. If we are able to write it then I am hoping that the project will help me in my professional career in the Air Force.

Yes, I am in ROTC here and it rocks!! I am in my fourth year and I have the position of female cadet retention in the detachment. It is super fun because I get to meet cool female cadets, encourage, advise, and PT with them!

That’s pretty much all that I’ve been up to this semester so far, keep checking my blog for more updates, fun, facts, and useful info! If you have any questions for me please feel free to comment below 🙂
