Religious Devices: A Survey Of Technologies Of Worship., Hugh Davies
Responding to the unannounced spiritual mysticism surrounding contemporary technologies, a religiosity present in the prayer-like devotion of social media piety to the cultish intensity surrounding each iPhone launch, this paper aims to dispel presumptions of the spiritual in opposition to the technological by surveying a range of media devices specifically developed for religious purposes. More than connecting scholarship in technology, media and religion, this survey recommends a new arc in the cultural examination of technology. As curious media artefacts, religious devices are independently worthy of study but they also offer a material past to the so-called “religion of Silicon Valley ...

A Voice Activated Prosthetic Mode Of Control, 2019 University of Nebraska at Omaha
A Voice Activated Prosthetic Mode Of Control, Will Picken
Student Research and Creative Activity Fair
There are many options for a prosthetic mode of control. The most commonly created modes of control involve surface EMG (sEMG) and require that the user have well defined muscle activation in order to trigger the movement of the prosthetic. Unfortunately, many prosthetic users do not have the required muscle tone or strength to trigger these sensors, so the need for a control mechanism that doesn’t rely on sEMG is clear. This study focuses on the development of a low-cost, voice activated prosthetic mode of control compatible with the prosthetics developed by Dr. Zuniga and his research team.

An Electrooculography Prosthetic Control System, Walker Arce
Student Research and Creative Activity Fair
For many surface EMG (sEMG) prosthetic control systems, the muscles on the affected limb are used to trigger the control system. This can lead to fatigue in the user as they have to maintain continuous muscle activation and coactivation in order to achieve prosthetic control . The crux of any prosthetic control system is the human machine interface that is developed, and at present many control systems have complicated interfaces that limit the degrees of freedom of the prosthetics. This study focuses on the development of a low-cost prosthetic control peripheral that is compatible with the prosthetics developed by Dr ...

Reactive Ion Etching Selectivity Of Si/Sio2: Comparing Of Two ﬂuorocarbon Gases Chf3 And Cf4, 2019 Singh Center for Nanotechnology
Reactive Ion Etching Selectivity Of Si/Sio2: Comparing Of Two ﬂuorocarbon Gases Chf3 And Cf4, Meiyue Zhang, Pat Watson
Protocols and Reports
Two reactive ion etching (RIE) processes were studied to show the relative etch selectivity between SiO2 and Si using two ﬂuorocarbon gases, CF4 and CHF3. Results show that CHF3 gives better selectivity (16:1) over CF4 (1.2 :1). On the other hand, the etch rate of SiO2 of CF4 is approximately 52.8 nm/min, faster than CHF3 (32.4 nm/min).
Experimental Study And Modeling Of The Gm-I Dependence Of Long-Channel Mosfets, 2019 California Polytechnic State University, San Luis Obispo
Experimental Study And Modeling Of The Gm-I Dependence Of Long-Channel Mosfets, Michael Fong Cheng
Master's Theses and Project Reports
This thesis describes an experimental study and modeling of the current-transconductance dependence of the ALD1106, ALD1107, and CD4007 arrays. The study tests the hypothesis that the I-gm dependence of these 7.8 µm to 10 µm MOSFETs conforms to the Advanced Compact Model (ACM). Results from performed measurements, however, do not support this expectation. Despite the relatively large length, both ALD1106 and ALD1107 show sufficiently pronounced ‘short-channel’ effects to render the ACM inadequate. As a byproduct of this effort, we confirmed the modified ACM equation. With an m factor of approximately 0.6, it captures the I-gm dependence with sub-28 ...

Graduate College Dissertations and Theses
Machine-to-machine (M2M) communication is becoming an important aspect of warehouse management, remote control, robotics, traffic control, supply chain management, fleet management and telemedicine. M2M is expected to become a significant portion of the Industrial Internet and, more broadly, the Internet of Things (IoT). The environments in which M2M systems are expected to operate may be challenging in terms of radio wave propagation due to their cluttered, multipath nature, which can cause deep signal fades and signal depolarization. Polarization diversity in two dimensions is a well-known technique to mitigate such fades. But in the presence of reflectors and retarders where multipath ...

Weed And Crop Discrimination Through An Offline Computer Vision Algorithm, 2018 Olivet Nazarene University
Weed And Crop Discrimination Through An Offline Computer Vision Algorithm, Phillip J. Putney
With the recent global interest in organic farming and cultivation, many people are turning away from chemical-based herbicides and moving towards alternate methods to extirpate weeds living amongst their crops. Of the methods proposed, robotic weed detection and removal is the most promising because of its possibility to be completely autonomous. Several robust, fully-autonomous robots have been developed, although none have been approved for commercial use. This paper proposes a weed and crop discrimination algorithm that utilizes an excessive green filter paired with principal component analysis to detect specific spatial frequencies within an image corresponding to different types of weeds ...
