Athens, OH 19 April 2013 – As the semester winds down, projects I have been working on are coming to a close. I have just finished my Capstone for ME 3012 and will be presenting my findings with my partner. It has been a great exploration into controls, controller design and vibration analysis. I find it very exciting to be done. The use of Matlab and Simulink have been very helpful, and I am glad I have learned how to use these tools.
The above graphic is an example of our ball on a beam system for our Capstone. It was taken from the University of Michigan/Carnegie Mellon/University of Detroit Mercy controls and Simulink tutorials. For our project we are analyzing the system and designing a controller to keep a ball level on on a beam and balancing it. The general Idea, is we want to have the controller move the beam from an unstable position and bring the beam to a level position. This is done by taking the mass of the ball, length of the beam, angle and other parameters to account. I have found this class to be very fun, and to be able to have this project to show off is rewarding. The use of Matlab has been helpful in validating our findings.
I would like to take this knowledge and do something with controls for Senior Design next year. It is a very exciting topic. It is great to have this broad knowledge in so many subjects. I have no idea where I will be come this time next year with my Senior Design project. I am sure glad that I have this background because if my senior design requires a controller, I have the knowledge I have taken away from Dr. Bob’s ME 3013 Controls class here at Ohio University.

Athens, OH 26 November 2012 – A project I am finishing up for this semester is a Highway Safety project. In this class, we have been studying how to predict crashes based on elements of different types of roads, such as lane width, turning lanes, and phases of the stop lights. The project assigned is to actually perform a study and implement appropriate countermeasures to lower the number of crashes occurring at a location by 25%.
Each group had to pick a stretch of roadway that was at least a mile long and had two intersections. This roadway had to be divided into segments according to when portions of the roadway change. As an example, a speed limit change can divide a road into two segments. Our group had to go out to the roadway we chose and measure distances and fixed objects. We had to create drawings on AutoCAD in order to make collision diagrams. The next step was using online databases to find the crashes that actually occurred in 2009 and 2010. Through the actual crashes and the predicted number of crashes for these two years, we were able to predict how many crashes should have occurred throughout this year. Based on why these crashes occurred, we chose countermeasures to lower the expected number of crashes. After putting all of this together with pictures and other graphics, we have to present this project to the class and answer questions concerning our methods and reasoning.
This project is very useful to our education in this class. Sitting in class and learning how to do something is so much more different then actually doing this work ourselves. It helps to give us the confidence to conduct a study if we someday have to do this in our careers.

Athens, OH 24 November 2012 – This year has been very exciting and I have learned very much. One of my classes, Kinematics, has a term project everyone must complete. In groups of two, we have to choose a mechanism in which we analyze the position, velocity, acceleration, and the internal forces of this mechanism. My partner and I chose a 4-bar door hinge to analyze. We have to go through and derive all the formulas for analysis, as well as write a Matlab program that shows the motion of the door and links. The program also calculates the position, velocity, acceleration, and the internal forces inside the links.
The project has gone very well so far. As we have learned new topics throughout the semester, we have continuously been adding to our project. I have never been one to put things off till the last minute, and it has worked very well for this project. I have really enjoyed being able to look at something we see and use so often and be able to analyze and break it down and understand more about it. Below, there is an image of the mechanism my partner have been analyzing all semester.
Dr. Bob has been a great help in completing our project and helps point us in the right direction if we need any, he wants to make sure we have a complete understanding of the topics we discuss in class. At the end of this project, we will present our findings to the rest of the class. I am looking forward to finishing our ME 3011 Capstone project and seeing what other topics have been chosen in the class.

Athens, OH 20 November 2012 – The leaves are down and fall has officially arrived in Athens. With only three weeks left in this semester
I’m happy to say we are in the home stretch. Today is the last day of class before Thanksgiving break and I’m ready for the short break.
The final project for my Civil Engineering Experimental Methods class is due in two weeks and I’m excited about the open ended format of the project. The class is designed to give civil engineering seniors the knowledge to design and implement data acquisition and analysis systems on real world projects. Real world projects include structural health of buildings and bridges, highway loading and safety analysis, dynamic structural loading due to earthquakes, environmental monitoring and sampling of contaminated sites, or simple concrete maturity analysis. I and a group of three of my peers have chosen to review publications on highway loading and safety analysis. The project includes a peer review paper and a 15 minute presentation on our particular case studies. I enjoy public speaking and love presenting information pertinent to my field of study, so this project is right up
This fall isn’t only projects and homework, it’s also football season. I live with four other guys; our areas of study are civil engineering (me), engineering technology and management, middle childhood education, sociology, and chemistry. Despite our varied educational interests we can all still sit down to a good football game on Saturday, or any day of the week for that matter, and just enjoy the show. Although our Bobcats aren’t doing as well as I would like there is still plenty to be excited about around our house. I won’t mention team names, but two house teams are still undefeated. Let’s hope at least one team stays that way, I’d hate to see my 22 year old roommate cry.

Athens, OH 20 October 2012 – The end of the semester always comes with final projects, used to wrap up a course. This semester I am taking a class called industrial computer simulation. The course is all about modeling real world systems to be able to identify ways to improve and better it. For our final project in industrial computer simulation, we have the opportunity to model–or simulate–a specific unit in a hospital. I am excited to complete the project because it has the potential to be utilized in a real life setting; it is not just a problem from a textbook. For this assignment we were given actual data from the hospital, and even had the chance to visit the hospital to take a tour and ask questions, so that we could better understand the task at hand.
The goal of this assignment is to help the hospital better utilize their resources. These resources include nurses, rooms and beds. Better utilization of these resources could help the hospital save money by eliminating possible unnecessary processes, and better utilization of resources will also help to effectively treat more patients.
So far my group is not extremely far into the project. We haven’t yet completed a working model of the hospital unit, but have been discussing ways in which we can go about creating it. A lot of the work entails trial and error as we must create portions of the model, and check to see if it works as it is suppose to, like the actual hospital unit. Again, I am excited to complete the assignment and get feedback because this project has the potential to be utilized in the real world, and is not just a grade on a paper.
