Quantum Coherence And Entanglement In The Avian Compass, James A. Pauls, Yiteng Zhang, Gennady P. Berman, Sabre Kais

Birck and NCN Publications

The radical-pair mechanism is one of two distinct mechanisms used to explain the navigation of birds in geomagnetic fields, however little research has been done to explore the role of quantum entanglement in this mechanism. In this paper we study the lifetime of radical-pair entanglement corresponding to the magnitude and direction of magnetic fields to show that the entanglement lasts long enough in birds to be used for navigation. We also find that the birds appear to not be able to orient themselves directly based on radical-pair entanglement due to a lack of orientation sensitivity of the entanglement in the …

Accuracy Of A Simplified Analysis Model For Modern Skyscrapers, Jacob Scott Lee

Theses and Dissertations

A new simplified skyscraper analysis model (SSAM) was developed and implemented in a spreadsheet to be used for preliminary skyscraper design and teaching purposes. The SSAM predicts linear and nonlinear response to gravity, wind, and seismic loading of "modern" skyscrapers which involve a core, megacolumns, outrigger trusses, belt trusses, and diagonals. The SSAM may be classified as a discrete method that constructs a reduced system stiffness matrix involving selected degrees of freedom (DOF's). The steps in the SSAM consist of: 1) determination of megacolumn areas, 2) construction of stiffness matrix, 3) calculation of lateral forces and displacements, and 4) calculation …

The Effects Of Mismatches And Probe Tethering Configurations On The Stability Of Dna Duplexes On Surfaces, Kyle Evan Pratt

Theses and Dissertations

DNA microarrays are chip-based, analysis tools which can perform hundreds of thousands of parallel assays to determine the identity of genes or gene expression levels present in a sample. They have been identified as a key technology in genomic sciences and emergent medical techniques; however, despite their abundant use in research laboratories, microarrays have not been used in the clinical setting to the fullest potential due to the difficulty of obtaining reproducible results. Microarrays work on the principle of DNA hybridization, and can only be as accurate as this process is robust. Fundamental, molecular-level understanding of hybridization on surfaces is …

First Spectroscopic Identification Of Pyrocarbonate For High Co2 Flux Membranes Containing Highly Interconnected Three Dimensional Ionic Channels, Lingling Zhang, Xinyu Huang, Changyong Qin, Kyle Brinkman, Yunhui Gong, Siwei Wang, Kevin Huang

Faculty Publications

Identification of the existence of pyrocarbonate ion C₂O₅²⁻ in molten carbonates exposed to a CO₂ atmosphere provides key support for a newly established bi-ionic transport model that explains the mechanisms of high CO₂ permeation flux observed in mixed oxide-ion andcarbonate-ion conducting (MOCC) membranes containing highly interconnected three dimensional ionic channels. Here we report the first Raman spectroscopic evidence of C₂O₅²⁻ as an active species involved in the CO₂-transport process of MOCC membranes exposed to a CO₂atmosphere. The two new broad peaks centered at 1317 cm^{−1 …}

Frequency-Selective Surface Coupled Metal-Oxide-Metal Diodes, Edward C. Kinzel, Robert Laurent Brown, James Chris Ginn, Brian A. Lail, Brian A. Slovick, Glenn D. Boreman

Electrical Engineering and Computer Science Faculty Publications

Metal-Oxide-Metal diodes offer the possibility of directly rectifying infrared radiation. To be effective for sensing or energy harvesting they must be coupled to an antenna which produces intense fields at the diode. While antennas significantly increase the effective capture area of the MOM diode, it is still limited and maximizing the captured energy is still a challenging goal. In this work we investigate integrating MOM diodes with a slot antenna Frequency Selective Surface (FSS). This maximizes the electromagnetic capture area while minimizing the transmission line length which helps reduce losses because metal losses are much lower at DC than at …

Identifying Peer-To-Peer Traffic On Shared Wireless Networks, Simon Piel, Ej Jung

Annual ADFSL Conference on Digital Forensics, Security and Law

Tracing contraband downloads leads investigators to an IP address, and in turn Internet Service Providers (ISP) can provide a physical location using this IP address. However, most homes and offices share this IP address among many computers using wireless networks. In other words, there needs to be another investigation to find out which computer was responsible for contraband downloads. To make matters worse, these shared wireless networks often have vulnerabilities in access control such as using WEP or using weak passwords. In such cases, any computer in range, not necessarily at the given physical address, could be responsible. We use …

On Resolving The Cloud Forensics Conundrum, John Bagby

Annual ADFSL Conference on Digital Forensics, Security and Law

The “cloud” is idiom for an ill-defined set of online services. The cloud simultaneously offers IT savings and promises advances in functionality (e.g., ubiquity). However, the cloud also imposes poorly understood burdens on security and it may provoke injustice. Thus, the cloud presents a durable and seemingly irreconcilable conundrum for the digital forensics communit(ies). First, cloud proponents make efficiency promises for cloud services (SaaS, IaaS, PaaS). These translate well into the digital forensics domain. Indeed, the cloud may enable crowd sourcing of investigatory data vastly lowering costs of dispute resolution. For example, cloud-based litigation war rooms may reduce electronic discovery …

Cybercrime And Punishment: An Analysis Of The Deontological And Utilitarian Functions Of Punishment In The Information Age, Karim Jetha

Annual ADFSL Conference on Digital Forensics, Security and Law

This conceptual piece analyzes the role of criminal punishment and the nature of cyber crime to investigate whether the current punishment schemes are appropriate given the deontological and utilitarian goals of punishment: retribution, deterrence, incapacitation, and rehabilitation. The research has implications for policymaking in cybercriminal law.

Keywords: cybercrime, criminal law, punishment, retribution, deterrence, information economics

The Development Of Computer Forensic Legal System In China, Yonghao Mai, K. P. Chow, Rongsheng Xu, Gang Zhou, Fei Xu, Jun Zhang

Annual ADFSL Conference on Digital Forensics, Security and Law

The computer forensic discipline was established around 2000 in China, which was further developed along with Chinese judicial appraisal system in 2005. The new criminal and civil procedure laws of the People’s Republic of China was enacted on 1 Jan 2013. The new laws specified electronic data is legal evidence and has great impact on the current practice on handling electronic evidence. This paper introduces the electronic data and electronic evidence examination procedure in mainland China, the general concept of computer forensic legal system, the management of computer judicial experts, the management of computer judicial expertise institutions.

Developing Seismic Performance Factors For Prefabricated Bamboo Walls In Comparison To Conventional Timber Shear Walls, David Steenson, Davin Chan

Civil, Environmental and Sustainable Engineering Senior Theses

In order to address the issue of rising demand in resources from providing a growing population with housing, a team of professors and undergraduate students worked to study bamboo's possible utility as a structural element. This team proposed the use of bamboo as a substitute for timber in conventional light frame construction, specifically in the form of bamboo shear walls, which resist lateral loads such as those applied by earthquakes and winds. In order to demonstrate the adequacy of these proposed bamboo walls as a substitute to the control softwood walls, the team used the document FEMA P-795 to develop …
