    Gretchen is a mobile Fetch robot with a seven degree of freedom manipulator. Her current software generally creates motion plans that add a great deal of unnecessary movement to the solution path. This is a significant ...
  • Friske, Spencer (2016)
    Given life's scarcity of resources, decision-making is an omnipresent component of both society and the human experience. Individually, we routinely face choices that range from mundane to life changing. As a society, we ...
  • Pekerti, Dakota (2016)
    For my E90 project, I synthesized a robust model that may be used to evaluate both the optimal performance of residential solar PV systems and the effect of different policies regarding solar energy within different cities ...
  • McGinn, Christine (2016)
    This project investigated the use of genetic algorithms to design several types of analog filters. This process involved "mathematically describing" the correct filter behavior in the fitness function so that the genetic ...
  • Lehman-Borer, Ryerson (2016)
    In an age where computing power is cheaper than ever and memory is abundantly available, many forms of media are being converted to digital formats so they can be preserved, edited, shared, and explored more easily than ...
  • Lee, Ethan (2016)
    This report contains the structural design and analysis of three different steel frame 'pencil-thin' skyscrapers that would be hypothetically located in New York, NY. This project aims to compare different structural systems ...
  • Jowdy, Jessica (2016)
    A brain-computer interface (BCI) is a system that provides direct communication between cognitive activity and external systems. This project involved creating a BCI that allowed participants to learn how to control virtual ...
  • Guarini, Ascanio; Swartz, Kurtis (2016)
    We designed and built a photoplethysmogram (PPG) sensor that obtains an optically measured signal that contains frequency information of the user's heart rate. This sensor can be used for non-invasive patient monitoring ...
  • Gilchrist-Scott, Andrew; Taylor, Andrew (2016)
    The problem of automatically identifying humans in a space, tracking their motions, and predicting future locations in real time has not been attempted in the current literature. We propose a system to do this, by establishing ...
  • Dulin, Isaac (2016)
    The ability to map a previously unseen environment is often considered a prerequisite for any truly autonomous robot. Since sensors and motors are often imprecise, it is necessary to find a way to identify and correct error ...
  • Clark, Conor; Heppe, Madison (2016)
    St. Josephs University (SJU) currently has outdoor tennis courts that can only be used in daylight hours and good weather. SJU's Head Tennis Coach Ian Crookenden and President's Executive Council Member Bill Ringle have ...
  • Bowen, Connie; Karol, Jess (2016)
    Controlled environment agriculture (CEA) is any system that alters the environment in which crops are grown. This environmental intervention can range from low-tech plastic crop covers to high-tech computer controlled ...
  • Borris, Mercer; Brakeman, Sara (2016)
    In high­-rise apartment buildings, there are many pipes as part of the supply and drainage system for potable water. Leaks in these pipes result in a waste of usable water and money, especially when they are internal. In ...
  • Emery, Christine (2016)
    In this E90, I propose a novel laparoscopic grasper design that is intended to reduce the risk of inadvertent tissue damage during surgery. The small, V-shaped jaws of traditional laparoscopic graspers apply high and uneven ...
  • Alto, Cosmo (2016)
    A melodic audio signal harmonization algorithm was designed in MATLAB, implemented in C code, then run on a C2000 Piccolo F28069 Control Card and Experimenter's Kit from Texas Instruments. Using four output buffers, the ...
  • Dahmm, Hayden Wallace (2015-05)
    Distributed Generation (DG) will be an important feature of carbon mitigation policies, and understanding the limitations on generator investment will help form more effective policy options. This study explored the tradeoff ...
  • Liu, Ruisen (Eric) (2015)
    This project explores the design and implementation of walking patterns for humanoid robots. This report presents a brief introduction to human walking and the exploration of two walking pattern generation techniques for ...
  • Cochrane, Caleb (2015)
    Global climate change is one of the most impressive and daunting challenges of the 21st century, that must ultimately be dealt with by changing the way people consume natural resources. Many people are committed to doing ...
  • Wu, Sizhao (Bill) (2015)
    A bench-scale shake table was designed and constructed for the Swarthmore College Engineering Department. The frame of the shake table was made of Unistrut. It's powered by a motor with a complete built-in servo control ...
  • Macfarland, Neil; Weinthal, Noah (2015)
    The concept of a 'racing line' is an integral part of competitive racecar driving. While many drivers develop a sense for this optimal path around a racecourse intuitively, the physics governing basic vehicle dynamics ...
