The design process in this system includes the process of data acquisition, training, feature extraction, testing and classification with artificial neural networks. Based on the results of the performance of this device to record ECG signals on …

Flight Test Data System For Strain Measurement, Zachary David Wilson

Master's Theses

This thesis describes the design and evaluation of two devices to be included in the next generation of the family of devices called the Boundary Layer Data System (BLDS). The first device, called the Quasi-Static Strain Data Acquisition System, is a continuation of the BLDS-M series of devices to be known as the Flight Test Data System (FTDS) that uses a modular approach to acquire non-flow, quasi-static mechanical strain measurements. Various breakout boards and development boards were used to synthesize the device, which were housed by a custom PCB board. The system is controlled by the Simblee^TM System on …

Improving 3d Printed Prosthetics With Sensors And Motors, Rachel Zarin

Honors Projects

A 3D printed hand and arm prosthetic was created from the idea of adding bionic elements while keeping the cost low. It was designed based on existing models, desired functions, and materials available. A tilt sensor keeps the hand level, two motors move the wrist in two different directions, a limit switch signals the fingers to open and close, and another motor helps open and close the fingers. All sensors and motors were built on a circuit board, programmed using an Arduino, and powered by a battery. Other supporting materials include metal brackets, screws, guitar strings, elastic bands, small clamps, …

Neurostimulator With Waveforms Inspired By Nature For Wearable Electro-Acupuncture, Jose Aquiles Parodi Amaya

LSU Doctoral Dissertations

The work presented here has 3 goals: establish the need for novel neurostimulation waveform solutions through a literature review, develop a neurostimulation pulse generator, and verify the operation of the device for neurostimulation applications.

The literature review discusses the importance of stimulation waveforms on the outcomes of neurostimulation, and proposes new directions for neurostimulation research that would help in improving the reproducibility and comparability between studies.

The pulse generator circuit is then described that generates signals inspired by the shape of excitatory or inhibitory post-synaptic potentials (EPSP, IPSP). The circuit analytical equations are presented, and the effects of the circuit …

Autonomous Watercraft Simulation And Programming, Nicholas J. Savino

Undergraduate Theses and Capstone Projects

Automation of various modes of transportation is thought to make travel more safe and efficient. Over the past several decades advances to semi-autonomous and autonomous vehicles have led to advanced autopilot systems on planes and boats and an increasing popularity of self-driving cars. We simulated the motion of an autonomous vehicle using computational models. The simulation models the motion of a small-scale watercraft, which can then be built and programmed using an Arduino Microcontroller. We examined different control methods for a simulated rescue craft to reach a target. We also examined the effects of different factors, such as various biases …

A Bioinstrumentation Active Learning Educational Module: The Design Of A Working Temperature Sensor Using A Ntc Thermistor, Baylor Bush

Biomedical Engineering Undergraduate Honors Theses

The Department of Biomedical Engineering at the University of Arkansas has continued to develop over the years, with more students enrolling in the program each year. Within the first biomedical engineering course, Introduction to Biomedical Engineering, various topics are introduced to students, and the topic of bioinstrumentation has been one of the most complex and difficult topics for students to comprehend through just a few lectures. In order to aid students in grasping these intricate concepts, an active learning module was developed in which students can work in groups to build a simple thermistor circuit as a temperature sensor. The …

Automated Greenhouse Watering System For Schenectady Arc, Lisa Gu

Honors Theses

All people need to feel useful and able to perform productive jobs. Since 1952, the ARC has strived to provide people with developmental disabilities the resources, services, and support that enable them to advocate and participate within their communities. One way in which the ARC accomplishes this mission is by encouraging people with disabilities to develop skills and hobbies that give them independence and purpose. An integral part of their center is the greenhouse. Individuals at the Maple Ridge Center are responsible for operating the water system to irrigate the plot daily and ensuring that the proper amount of water …

Low-Cost, Open-Source, And Low-Power: But What To Do With The Data?, Jeffery S. Horsburgh, Juan Caraballo, Maurier Ramírez, Anthony K. Aufdenkampe, David B. Arscott, Sara Geleskie Damiano

Civil and Environmental Engineering Faculty Publications

There are now many ongoing efforts to develop low-cost, open-source, low-power sensors and datalogging solutions for environmental monitoring applications. Many of these have advanced to the point that high quality scientific measurements can be made using relatively inexpensive and increasingly off-the-shelf components. With the development of these innovative systems, however, comes the ability to generate large volumes of high-frequency monitoring data and the challenge of how to log, transmit, store, and share the resulting data. This paper describes a new web application that was designed to enable citizen scientists to stream sensor data from a network of Arduino-based dataloggers to …

Soundboard: Planar Tracking For Instrument Control, Peter O'Sullivan

ENGS 86 Independent Projects (AB Students)

The Soundboard is the central component of Syrinx, a synthesizer instrument invented by Spencer Topel. A generated audio signal is transduced through the Soundboard, and by manually adjusting the positioning of its top metal plane, the user can manipulate the encased soundwaves before they are transduced back into a signal and output. My task for this project was to add controller functionality to the Soundboard component by implementing control voltages that carry information about its planar tilt, yaw, and altitude. These voltages can be used to modulate various digital parameters and further affect the sonic output of the instrument. Further, …

An Evaluation Of Two Controller Implementations For An Inverted Pendulum On Cart System, Shaima Abdul Wahab Ali Al Habsi

Electrical Engineering Theses

Various embedded systems are available for control system design and implementation in either lab experiments of postgraduate and undergraduate courses in the area of dynamics and control, or in experimental academic research. The focus of this Master thesis project is set to study, compare and evaluate the performance of two options of controller implementations ranging from a low-cost microcontroller based embedded system to a relatively high-end, high-cost controller prototyping system. In the work reported here, the Arduino® DUE board, which is an Atmel ARM Cortex CPU based, and the dSPACE_® DS1104 prototyping system are used. Another objective of the …

An Airlifted Tidal Mesocosm For Oil Degradation Studies, Daniel Christopher Alt

LSU Doctoral Dissertations

Mesocosms were constructed to allow scientists to isolate variables in a microtidal marsh environment, mimicking the natural conditions found in Terrebonne Bay. The control offered by these mesocosms is given by a process control system that takes user inputs and automates water movement. Twelve mesocosms were constructed, each holding 4.02 m³ (142 ft³) of marsh soil and 3.88 m³ (137 ft³) of water to give 3 experimental levels and a control, all in triplicate.

Each mesocosms that was constructed contained marsh plants in soil plugs 9 feet in diameter and 3 feet deep. These …

Dual-Axis Solar Tracker, Alazone Smith

All Undergraduate Projects

The global energy crisis and continued supporting evidence of global climate change have begun to shift the world economies towards solutions that solve both challenges. Solar power has become one of the most recognizable and popularized renewable energy methods to date. In comparison to other photovoltaic systems, this project demonstrates the performance advantages of a dual-axis solar tracker. It also addressing its viability on a non-commercial scale. The objective was to improve upon previous solar tracker projects at Central Washington University by adding another axis to the system. This system implements both an actuator and a stepper motor to examine …
