Autonomous Speed Control For Kia Optima, 2017 Kennesaw State University
Autonomous Speed Control For Kia Optima, Andrew J. Combs, Kyle Fugatt, Kevin Mcfall
The Kennesaw Journal of Undergraduate Research
The standard method for speed control is the cruise control system built into most modern vehicles. These systems employ a PID controller which actuates the accelerator thus, in turn, maintains the desired vehicle speed. The main drawback of such a system is that typically the cruise control will only engage above 25 mph. The goal of this paper is to describe a system which we used to control vehicle speed from a stop to any desired speed using an Arduino microcontroller and a CAN BUS shield, from where autonomous features can be built upon. With this system, we were able ...

Wireless Audio Bridge, 2017 California Polytechnic State University, San Luis Obispo
Wireless Audio Bridge, Daniel L. Hodges
Bluetooth, a wireless technology standard used to exchange data using radio transmissions, has made a significant impact on the audio technology industry, specifically the way people listen to music. This technology enables a wireless listening experience, eliminating the need for wires or cables between audio devices as previously required. Audio can transmit from a cellphone or laptop (an output device) to a pair of headphones or speakers (an input device) without any physical connection. Compared to alternative wireless listening solutions (i.e. FM transmitter, radio broadcast), Bluetooth offers greater reliability, audio fidelity, portability, and ease of use. To obtain this ...

Logic Tiles, 2017 California Polytechnic State University, San Luis Obispo
Logic Tiles, Andrew Wheeler, Tristan Lennertz
This project was originally conceived by Professor Andrew Danowitz as he considered the restructuring of the introductory digital design course at Cal Poly. As it stands now, students apply their knowledge of boolean algebra and combinatorial logic through the programming of a Field Programmable Gate Array (FPGA) using a Hardware Descriptive Language (HDL). While this is the industry standard for designing large, complex digital circuits, and is an fundamental skill to learn, there is a lack of actual circuit building in the process that can cause a disconnect from theory to application for students who have little-to-no experience with digital ...
Investigating Read/Write Aggregation To Exploit Power Reduction Opportunities Using Dual Supply Voltages, 2017 Washington University in St Louis
Investigating Read/Write Aggregation To Exploit Power Reduction Opportunities Using Dual Supply Voltages, Gu Yunfei
Engineering and Applied Science Theses & Dissertations
Power consumption plays an important role in computer system design today. On-chip memory structures such as multi-level cache make up a significant proportion of total power consumption of CPU or Application-Specific Integrated Circuit (AISC) chip, especially for memory-intensive application, such as floating-point computation and machine learning algorithm. Therefore, there is a clear motivation to reduce power consumption of these memory structures that are mostly consisting of Static Random-Access Memory (SRAM) blocks. In this defense, I will present the framework of a novel dual-supply-voltage scheme that uses separate voltage levels for memory read and write operations. By quantitatively analyzing the cache ...

Vehicle Occupancy Detection System, Hannah Miller, Justin Wert, Kelsey Lunberg
Honors Theses AY 16/17
Personal vehicles often become traps for unattended occupants throughout the year. Sadly, this can lead to severe health complications or even death if exposed for too long. Although these complications arise primarily in hot climates, it has been demonstrated that they can happen in any environment. Prolonged exposure to an unfamiliar and often dangerous setting without competent human intervention can be detrimental to health. This problem predominantly impacts pets and young children. In an effort to reduce these preventable health complications and possible deaths, we have developed a vehicle occupancy detection system.
The goal of developing this occupancy detection system ...
An Exact Analysis For Four-Order Acousto-Optic Bragg Diffraction Which Incorporates Both Incident Light Angle And Sound Frequency Dependencies, Adeyinka Sunday Ademola
Electrical Engineering Theses
This thesis extends the prior work which produced an exact solution to the four-order acousto-optic (AO) Bragg cell with assumed fixed center frequency and with exact Bragg angle incident light. The extension predicts the model that incorporates the dependencies of both the input angle of light and the sound frequency. Specifically, a generalized 4th order linear differential equation (DE), is developed from a simultaneous analysis of four coupled AO system of DEs. Through standard methods, the characteristic roots, which requires solving a quartic equation, is produced. Subsequently, a derived system of homogeneous solutions, which absorbs the roots obtained using ...
Implementation Of Range Autofocus For Sar Radar Imaging, 2017 Kennesaw State University
Implementation Of Range Autofocus For Sar Radar Imaging, Nicholas J. Testin, Philip Davis
Honors College Capstones and Theses
The range calculation for an FMCW radar depends on accurate linear modulation. In some circumstances, linear modulation may not be available and must be corrected for. This paper describes an autofocus technique used to correct for phase error due to non-linearities in the components of a FMCW radar. Also described here is the algorithm used in calculating the phase error and application of the phase correction with triangle modulation. Known errors were calculated at certain distances and applied to correcting the phase of data taken at similar distances. The results given were generated using a SAR working outside linear ranges.

Design And Test Of A Gate Driver With Variable Drive And Self-Test Capability Implemented In A Silicon Carbide Cmos Process, Matthew Barlow
Theses and Dissertations
Discrete silicon carbide (SiC) power devices have long demonstrated abilities that outpace those of standard silicon (Si) parts. The improved physical characteristics allow for faster switching, lower on-resistance, and temperature performance. The capabilities unleashed by these devices allow for higher efficiency switch-mode converters as well as the advance of power electronics into new high-temperature regimes previously unimaginable with silicon devices. While SiC power devices have reached a relative level of maturity, recent work has pushed the temperature boundaries of control electronics further with silicon carbide integrated circuits.
The primary requirement to ensure rapid switching of power MOSFETs was a gate ...
Short-Circuit Protection For Low-Voltage Dc Distribution Systems Based On Solid-State Circuit Breakers, 2017 University of Arkansas, Fayetteville
Short-Circuit Protection For Low-Voltage Dc Distribution Systems Based On Solid-State Circuit Breakers, Sharthak Munasib
Theses and Dissertations
Proper short-circuit protection in dc distribution systems has provided an austere challenge to researchers as the development of commercially-viable equipment providing fast operation, coordination and reliability still continues. The objective of this thesis is to analyze issues associated with short-circuit protection of low-voltage dc (LVDC) distribution systems and propose a short-circuit protection methodology based on solid-state circuit breakers (SSCBs) that provides fault-current limiting (FCL). Simulation results for a simplified notional 1-kVdc distribution system, performed in MATLAB/SIMULINKTM, would be presented to illustrate that SSCB solutions based on reverse-blocking integrated gate-commutated thyristors (RB-IGCT) are feasible for low-voltage dc distribution systems but ...

Theses and Dissertations
This thesis demonstrates the process of creating a radiation hardened and extreme temperature operating comparator from start to finish in the 90 nm SiGe 9HP process node. This includes the entire design flow from examining comparator topologies, to designing the initial comparator circuits, to simulating the comparator over a temperature range of -196°C to 125°C, and finally the testing of the fabricated circuit. To verify the circuit would work at low temperatures, several new device models were created that could be used for simulations at -196°C. In addition to its properties as a standalone comparator, the circuit ...
Hexarray: A Novel Self-Reconfigurable Hardware System, 2017 Boise State University
Hexarray: A Novel Self-Reconfigurable Hardware System, Fady Hussein
Boise State University Theses and Dissertations
Evolvable hardware (EHW) is a powerful autonomous system for adapting and finding solutions within a changing environment. EHW consists of two main components: a reconfigurable hardware core and an evolutionary algorithm. The majority of prior research focuses on improving either the reconfigurable hardware or the evolutionary algorithm in place, but not both. Thus, current implementations suffer from being application oriented and having slow reconfiguration times, low efficiencies, and less routing flexibility. In this work, a novel evolvable hardware platform is proposed that combines a novel reconfigurable hardware core and a novel evolutionary algorithm.
The proposed reconfigurable hardware core is a ...
A Sub-Threshold Low-Power Integrated Bandpass Filter For Highly-Integrated Spectrum Analyzers, 2017 University of Tennessee, Knoxville
A Sub-Threshold Low-Power Integrated Bandpass Filter For Highly-Integrated Spectrum Analyzers, Benjamin David Roehrs
Low-power analog filter banks provide frequency analysis with minimal space requirements, making them viable solutions for integrated remote audio- and vibration-sensing applications. In order to achieve a balance between the length of deployable service and system performance, a critical requirement of such remote sensor networks is low-power consumption, due to the constraints imposed by on-board battery cells.
In this work, the design and implementation of a sub-threshold complementary metal-oxide semiconductor (CMOS) integrated low-power tunable analog filter channel for Oak Ridge National Laboratory is presented. Project specifications required a tunable, high-order, monolithic bandpass filter channel with small chip area and low ...
Stringless Guitar, 2017 University of Akron
Stringless Guitar, Kue Z. Yang, Anthony Batey, Dominic Mercorelli, Nathaniel Hawk
Honors Research Projects
The aim of this project is to improve the design of a typical guitar by designing a digital stringless guitar. Due to the nonlinearities inherent in a guitar, it would be difficult to reproduce guitar tones by summing harmonic components; therefore, digital samples of guitar tones were taken in order to preserve these unique and wonderfully sounding tones. These digital samples were stored in the guitar and used to produce its tones when played. The digital guitar includes fingerboard position sensors as well as strum sensors for each string. The fingerboard position sensors detect the player’s fingers at discrete ...
