Comparison And Renormalization Of Holocene Paleointensity Records From Central North America (17°N–51°N, 205°E–295°E), Steve P. Lund, Marci Richardson, Ken Verosub, John King, Duane Champion, Guillame St-Onge

Graduate School of Oceanography Faculty Publications

This paper develops a composite absolute paleointensity record for Holocene paleomagnetic secular variation (PSV) from central North America. Twelve full-vector (inclination, declination, paleointensity) PSV records were assessed in order to build the composite record. Nine of the paleointensity records come from sediment paleomagnetic studies and are considered relative in intensity. Three of the paleointensity records come from absolute paleointensity measurements of archeological materials and lava flows. This paper develops a new method to normalize the sediment relative paleointensity records to the absolute intensity records. The final composite paleointensity record describes intensity variability over a region of Central North America delineated …

On The Mobility Of Small Aperture Telescopes For Initial Orbit Determination And Apparent Magnitude Derivation Of Low Earth Satellites, Jonathan Ian Hernandez

Master's Theses

Maintaining Space Domain Awareness (SDA) of satellites in low Earth orbit (LEO) requires effective methods of tracking and characterization. Optical measurements of these objects are generally sparse due to limited access intervals and high angular rates. Light pollution and geographic obstructions may also preclude consistent observations. However, a mobile small aperture telescope grants the ability to minimize such environmental effects, thereby increasing capture likelihoods for objects within this regime. By enhancing LEO satellite visibility in this way, extensive orbital and visual data are obtainable.

An 8-inch Meade LX200GPS telescope equipped with a Lumenera SKYnyx2-0M CCD camera comprises the system that …

Indoor Positioning Using Synchronized Ultrasonic Ofdma Signals, Julian Bartolone

Master's Theses

This paper proposes a method of short-range indoor localization using differential phase measurements of synchronized two-tone ultrasonic signals in an Orthogonal Frequency Multiple Access (OFDMA) scheme. This indoor positioning system (IPS) operates at an ultrasonic frequency of approximately 40kHz and synchronizes using an infrared signal. The OFDMA scheme allows for a receiver to process the signals from multiple transmitters continuously without the signals interfering with each other. The phases of the signals are measured using Goertzel Filters, allowing for low-complexity frequency content analysis. A MATLAB simulation using the proposed localization method is performed using four transmitter nodes in the corners …

Willingness To Pay For Fact-Checking About Immigration: The Effect Of Partisan Cues, Jennifer Morales

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

I analyze the results of an online experiment designed to elicit individuals’ willingness to pay for fact-checking of statements related to immigration. Using a control and treatment group, I test whether individuals’ willingness to pay is affected by partisan cues. First, I outline this research’s position related to existing literature. I then describe the experimental design and analyze the results. Partisan cues are shown to have no statistically significant effect on participants’ willingness to pay for fact-checking.

Beyond Data Ownership, Ignacio Cofone

Cardozo Law Review

Proposals for data ownership are widely misunderstood, aim at the wrong goal, and would be self-defeating if implemented. This Article, first, shows that data ownership proposals do not argue for the bundle of ownership rights that exists over property at common law. Instead, these proposals focus on transferring rights over personal information solely through consent.

Second, this Article shows the flaws of a property approach to personal information. Such an approach magnifies well-known problems of consent in privacy law: asymmetric information, asymmetric bargaining power, and leaving out inferred data. It also creates a fatal problem: moral hazard where corporations lack …

Improvement Of The Fault Tolerance In Iot Based Positioning Systems By Applying For Redundancy In The Controller Layer, Nawzad K. Al-Salihi

Baghdad Science Journal

In recent years, the positioning applications of Internet-of-Things (IoT) based systems have grown increasingly popular, and are found to be useful in tracking the daily activities of children, the elderly and vehicle tracking. It can be argued that the data obtained from GPS based systems may contain error, hence taking these factors into account, the proposed method for this study is based on the application of IoT-based positioning and the replacement of using IoT instead of GPS. This cannot, however, be a reason for not using the GPS, and in order to enhance the reliability, a parallel combination of the …

Analyzing Racial And Economic Disparities In The United States’ Pretrial Detention Policies, Mariela Hollines

Undergraduate Honors Theses

Racial injustices and economic inequalities are evident throughout the criminal justice system. These are attributed to many factors such as the pretrial and detention process. The foundation of bail and pretrial policies in colonial times began the cycle of racial and economic disparities in the justice system. To reduce these disparities, currently practiced pretrial policies must be analyzed and adjusted to combat these insecurities that develop. The purpose of this study is to suggest pretrial policies that reduce racial and economic insecurities in the criminal justice system because these negatively impact the lives of people of color in the United …

Arbitrating Copyright Disputes In Egypt, Islam Mohamed

Maurer Theses and Dissertations

Egypt is witnessing increasing difficulty in implementing and practicing protectionist policies for intellectual property rights, which includes copyright as a fundamental element. Since the Egyptian judicial system is exclusively concerned with adjudicating all disputes, it has become increasingly burdened in recent decades due to this monopoly. As a result, the Egyptian judiciary is witnessing a significant slowdown in resolving conflicts and procedural obstacles which delay the restitution of Intellectual property rights to its owners. Thus, we believe that applying arbitration will contribute to resolving copyright disputes in advance on one hand and will encourage an attractive climate in such matters …

Spatiotemporal Pattern Detection With Neuromorphic Circuits, Robert C. Ivans

Boise State University Theses and Dissertations

In this dissertation, neuromorphic circuits are used to implement spiking neural networks in order to detect spatiotemporal patterns. Unsupervised training and detection-by-design techniques were used to attain the appropriate connectomes and perform pattern detection.

Unsupervised training was performed by feeding random digital spikes with a repeating embedded spatiotemporal pattern to a spiking neural network composed of leaky integrate-and-fire neurons and memristor-R(t) element circuits which implement spike-timing-dependent plasticity learning rules.

Detection-by-design was achieved using neuromporphic circuits and digital logic gates. When detection-by-design was achieved using both neuromorphic circuits and digital logic gates, a network was created of spatiotemporal pattern detector circuits, …
