Conceptual design of an on-board optical processor with components

The specification of components for a spacecraft on-board optical processor was investigated. A space oriented application of optical data processing and the investigation of certain aspects of optical correlators were examined. The investigation confirmed that real-time optical processing has made significant advances over the past few years, but that there are still critical components which will require further development for use in an on-board optical processor. The devices evaluated were the coherent light valve, the readout optical modulator, the liquid crystal modulator, and the image forming light modulator

Diversification and the Taxation of Capital Gains and Losses

Current U.S. law nets the total portfolio of realized capital gains and losses to compute capital gains taxes. Prior research, however, typically ignores the implication of this provision, i.e., the marginal tax rate for a specific gain or loss depends on the taxpayer's total portfolio of realized gains and losses. We find that these nettings introduce complexity into the relation between share values and capital gains taxes, creating an incentive to diversify. For firms with stock returns that are positively (negatively) correlated with those of the overall market, share values generally are decreasing (increasing) in the capital gains tax rate.

A study to analyze six band multispectral images and fabricate a Fourier transform detector

An automatic Fourier transform diffraction pattern sampling system, used to investigate techniques for forestry classification of six band multispectral aerial photography is presented. Photographs and diagrams of the design, development and fabrication of a hybrid optical-digital Fourier transform detector are shown. The detector was designed around a concentric ring fiber optic array. This array was formed from many optical fibers which were sorted into concentric rings about a single fiber. All the fibers in each ring were collected into a bundle and terminated into a single photodetector. An optical/digital interface unit consisting of a high level multiplexer, and an analog-to-digital amplifier was also constructed and is described

Smart Factories, Dumb Policy? Managing Cybersecurity and Data Privacy Risks in the Industrial Internet of Things

Interest is booming in the so-called Internet of Things (IoT). The Industrial Internet of Things (IIoT) is one application of this trend and involves the use of smart technologies in a manufac- turing context. Even though these applications hold the promise to revolutionize manufacturing, there are a number of outstand- ing cybersecurity and data privacy issues impacting the realiza- tion of the myriad benefits promised by IIoT proponents. This ar- ticle analyzes some of these pressing issues, focusing on: (1) critical infrastructure protection and cybersecurity due diligence, (2) trends in transatlantic data privacy protections, and (3) the regulation of new technologies like artificial intelligence (AI) and blockchain. The aticle concludes with a list of recommendations for state and federal policymakers to consider in an effort to harden the IIoT along with the supply chains critical to the con- tinued development of smart factories

Seeking a Safe Harbor in a Widening Sea: Unpacking the Schrems Saga and What It Means for Transatlantic Relations and Global Cybersecurity

The Article is structured as follows. Part I examines Schrems I (Schrems v. Data Protection Commissioner) and the fall of the Safe Harbor regime. Part II analyzes Schrems II (Data Protection Commissioner v. Facebook & Max Schrems) along with the rise and fall of Privacy Shield. Part III focuses on opportunities to bridge the data governance divide and present a united front to help ensure a free, open, interoperable, secure, and resilient vision for cyberspace. This abstract has been adapted from the author\u27s introduction

A Midwestern culture of civility: Student activism at the University of Northern Iowa during the Maucker years (1967-1970)

This project examines the changing social dynamic of those affiliated with the University of Northern Iowa during the latter half of the 1960s, with special emphasis on student activism and the changing attitudes of administrators and community members. This project intends to use the medium of alternative newspapers as a central component in the analysis of the time studied and as an unfiltered voice of student dissent. By narrowing the focus of this project to an individual university and community, an intimate narrative emerges that acts as a testament of the overwhelming atmosphere of change that engulfed American colleges throughout the late 1960s. Furthermore, I suggest that apathy at American colleges may not have derived from the characteristics of students, but, in fact, was the result of policies and an authoritarian culture that stressed civility and limited social activism. This culture of cultivated courtesy made Iowa aesthetically pleasing, a place where rural folk were courteous, smiling and civil. But when it came to student protest and dissent, the influence of cultivated courtesy was powerful: protesters were dismissed, vilified, and delegitimized when perceived to be failing to adhere to the social expectation of manners and civility. Finally, this project examines the relationships between administrators, faculty members, and students from within the context of education. This line of analysis suggests a schism in the ideological approaches to instruction; with one school of thought embracing structure and stability, while the other, promoted controversy and experience as modes of self‐enlightenment

On Climate Change and Cyber Attacks: Leveraging Polycentric Governance to Mitigate Global Collective Action Problems

Although cyberspace and the atmosphere are distinct arenas, they share similar problems of overuse, difficulties of enforcement, and challenges of collective inaction and free riders. With weather patterns changing, global sea levels rising, and temperatures set to exceed 1.5 degrees Celsius by 2100, climate change is a problem that affects the entire world. Yet its benefits are dispersed, and its harms are often concentrated. Similarly, much of the cost of cyber attacks is focused in a few nations even as others are becoming havens for cybercriminals. Yet it is also true that actions taken by a multiplicity of actors on a small scale can impact both the global climate change problem and the cause of promoting a global culture of cybersecurity. This Article tracks the evolution of the climate change regime, focusing both on the top-down UN Framework Convention on Climate Change and bottom-up bilateral and regional efforts, and then compares and contrasts this history with Internet governance. The potential of polycentric governance to mitigate the twin global collective action problems of climate change and cyber attacks is assessed as policymakers increasingly head toward a polycentric future
